According to the high-temperature hot air blower capable of gathering energy and generating heat of the invention, a pneumatic energy conversion heat-generating mechanism is adopted, cold air is directly processed into hot air, any heat source or heat medium (electric heating wires, electric heating tubes, electric heating plates, coal furnaces, oil furnaces, gas furnaces, etc.) is not required, the hot air blower operates solely by itself to convert mechanical energy into thermal energy, which is then discharged through an air outlet of the hot air blower for use. The high-temperature hot air blower capable of gathering energy and generating heat adopts a gas collision & friction & stagnation heat-generating mechanism to promote energy conversion from mechanical energy to thermal energy, generates heat, increases gas temperature and produces high-temperature hot air. The so-called gas collision & stagnation heat-generating mechanism refers to the fact that one or more high-speed gas flows collide each other by being ejected against or cross each other, or one or more high-speed gas flows collide against flow channel parts, or the mechanical energy of the gas flows promotes internal friction of the flow channel parts, decelerates and decompresses, and the pressure reduced by the gas flows converts the speed energy (kinetic energy) into thermal energy to generate heat and produce high-temperature hot air.
Various existing ventilators, blowers, gas compressors, compressors and the like can only produce cold air, and compared with these various machines, the high-temperature hot air blower capable of gathering energy and generating heat can produce hot air, that is, compared with the cold air machine, the hot air blower is suitable for production and life where hot air is required.
Like the existing cold air machines such as various ventilators, blowers and the like, the hot air blower of the invention also has various sizes including large, medium and small, from tens of watts to tens of kilowatts, hundreds of kilowatts and thousands of kilowatts, with the generated air volume from a few cubic meters per second, tens of cubic meters per second to hundreds of cubic meters per second; the generated air pressure can be tens of Pa, hundreds of Pa, thousands of Pa and tens of thousands of Pa; the temperature of the generated hot air may be several degrees Celsius, tens of degrees Celsius, and hundreds of degrees Celsius.

The hot air blower is more energy-saving than the cold air machine, which is beneficial to environmental protection.
According to the invention, the energy-gathering heat generator is provided on the side wall of the machine housing inner-side channel, the energy-gathering heat generator comprises the heat generator transmission protective cover, the heat generator friction heat-generation body, and the heat generator heat-insulation isolation wall; the heat generator transmission protective cover is disposed outside the energy-gathering heat generator and is connected with the heat generator friction heat-generation body with their side surfaces attached; the heat generator transmission protective cover is composed of tough and resilient materials (such as plastic plates, nylon plates, nylon cloth, synthetic fiber fabrics, plush, ceramics, cotton cloth, gold silk fabrics, leather, liquid glue, paint and the like) with good heat transfer performance. The heat generator transmission protective cover prevents high-speed air flow from directly colliding against the heat generator friction heat-generation body and protects the heat generator friction heat-generation body from being worn and broken; the heat generator transmission protective cover directly receives the impact of the high-speed air flow, directly transfers mechanical energy delivered by the high-speed air flow to the heat generator friction heat-generation body, and promotes the heat generator friction heat-generation body to generate heat through internal layer friction. Moreover, the heat generated by the heat generator friction heat-generation body can be rapidly transferred to the gas in the machine housing inner-side channel from inside to outside, the temperature of the gas is increased, and high-temperature hot air is produced.
The heat generator friction heat-generation body is disposed inside the energy-gathering heat generator, the outer side surface of the heat generator friction heat-generation body is in fit connection with the heat generator transmission protective cover, and the bottom surface of the heat generator friction heat-generation body is in fit connection with the heat generator heat-insulation isolation wall. The heat generator friction heat-generation body is composed of soft and elastic damping materials (soft rubber, sponge, soft plastic foam film, cotton, fluff, ceramic wool and the like). The structure of the heat generator friction heat-generation body is larger in thickness and volume than the heat generator transmission protective cover and the heat generator heat-insulation isolation wall, has a good damping function, and after external force is absorbed, the structure can cause intense internal layer friction, convert mechanical energy into thermal energy and generate heat. The heat generator friction heat-generation body is the main core component of the energy-gathering heat generator. The energy-gathering heat generator mainly depends on the heat generator friction heat-generation body to generate heat, so as to increase the gas temperature.
The heat generator heat-insulation isolation wall is arranged outside the bottom surface of the energy-gathering heat generator, one side surface of the heat generator heat-insulation isolation wall is in fit connection with the bottom surface of the heat generator friction heat-generation body, the other side surface of the heat generator heat-insulation isolation wall is in fit connection with the machine housing via the side wall of the inner-side channel (or the outer surface of other parts of the machine housing), and the whole energy-gathering heat generator is connected with the side wall of the inner-side channel of the machine housing (or the outer surface of other parts of the machine housing)via the heat generator heat-insulation isolation wall. The heat generator heat-insulation isolation wall is composed of a highly tough heat insulation material (such as heat insulation rubber, heat insulation adhesive tape, glass fabric and the like). The heat generator heat-insulation isolation wall is disposed between the side walls (or the outer surfaces of other parts of the machine body) of the machine housing inner-side channels, so that the heat generated by the heat generator friction heat-generation body can be prevented from being transferred to the side walls (or the outer surfaces of other parts of the machine body) of the machine housing inner-side channel and out of the machine body, so that the heat generated by the heat generator friction heat-generation body is guaranteed to be transferred to the gas in the machine housing inner-side channel by the heat generator transmission protective cover, and to increase the gas temperature in the machine housing inner-side channel.
During operation, the high-pressure high-speed air flow discharged by the impeller of the blower directly impacts the heat generator transmission protective cover of the energy-gathering heat generator on the side wall of the machine housing inner-side channel, so the heat generator transmission protective cover presses against the heat generator friction heat-generation body and transfers pressure power energy to the heat generator friction heat-generation body; after the heat generator friction heat-generation body absorbs the pressure power mechanical energy, intense internal layer friction is caused, with the mechanical energy converted into thermal energy, to generate heat. The heat generated by the heat generator friction heat-generation body is not transferred to the side wall of the machine housing inner-side channel to be dissipated outside the machine body by virtue of the heat insulation and isolation effect of the heat generator heat-insulation isolation wall, and the heat generated by the heat generator friction heat-generation body is mainly transferred to the high-pressure high-speed air flow in the machine housing inner-side channel by means of the heat generator transmission protective cover, so that the temperature of the air flow in the machine housing inner-side channel is increased and high-temperature hot air is produced.
Higher-pressure and higher-speed of the air flow discharged by the impeller to the machine housing inner-side channel would render more intense internal layer friction in the heat generator friction heat-generation body, and more heat is generated; so more heat is obtained by the air flow in the machine housing inner-side channel, and higher temperature is obtained. A more soft and elastic heat generator friction heat-generation body indicates a larger damping coefficient, and a larger damping coefficient of the energy-gathering heat generator would result in better damping friction heat generating effect, and more heat is generated, and greater temperature rise of the gas is obtained.
The pressure power mechanical energy carried by the high-pressure high-speed air flow is gathered at the heat generator friction heat-generation body in the energy-gathering heat generator, and is converted into thermal energy through friction to generate heat. Thus, the hot air blower is named as the energy-gathering heat-generating high-temperature hot air blower.
The energy-gathering heat generator is disposed on the side wall of the machine housing inner-side channel, which means that the energy-gathering heat generator can be disposed on the radial side wall (including a spiral tongue) of the machine housing inner-side channel independently, the energy-gathering heat generator can be disposed on the axial side wall of the machine housing inner-side channel independently, and the energy-gathering heat generators can be arranged on the axial side wall and the radial side wall of the machine housing inner-side channel simultaneously.
If the energy-gathering heat generator is disposed independently on the radial side wall or the axial side wall of the machine housing inner-side channel, the high-pressure high-speed air flow discharged by the impeller to the machine housing inner-side channel impacts the energy-gathering heat generator at one side surface or two side surfaces thereof, and partial mechanical energy of partial air flow of the high-pressure high-speed air flow discharged by the impeller to the machine housing inner-side channel is converted into thermal energy. If the energy-gathering heat generators are arranged on both the radial side wall and the axial side wall of the machine housing inner-side channel, most high-pressure high-speed air flow discharged by the impeller to the machine housing inner-side channel simultaneously impacts the energy-gathering heat generator, most of pressure power mechanical energy is converted into thermal energy through friction, so that more heat can be generated, and the temperature of the gas is further increased.
In order to further enhance the heat generation effect to generate more heat, the energy-gathering heat generator can also be disposed on the inner side surface of the blade disc, this energy-gathering heat generator has the same structural mechanism and performance characteristics as the energy-gathering heat generator disposed on the side wall of the machine housing inner-side channel; the energy-gathering heat generator is in fit connection with the inner side surface of the blade disc and prevents the high-pressure high-speed air flow from directly impacting the outer side surface of the impeller; the impact of the high-pressure high-speed air flow is directly absorbed, and the absorbed pressure power mechanical energy promotes friction to generate heat.
The energy-gathering heat generator can also be disposed on the outer side surface of the blade by wrapping the blade, and is in fit connection with the blade; the structure, performance and function of the energy-gathering heat generator are the same as those of the energy-gathering heat generator disposed on the side wall of the machine housing inner-side channel.
If both the inner side surface and the outer side surface of the blade disc of the impeller are simultaneously provided with the energy-gathering heat generator, the wall of the inner-side channel of the impeller is formed completely by the energy-gathering heat generator, and during operation, high-speed air flow produced by the blades impacts the energy-gathering heat generator from four directions or three directions (a disc impeller without the front blade) through the inner-side channel of the impeller, so that the peripheral side wall of the inner-side channel of the impeller can absorb mechanical energy to generate heat by friction.
According to the invention, the energy-gathering heat generators can be arranged at the machine housing air inlet and the machine housing air outlet respectively or simultaneously, the energy-gathering heat generator is respectively supported on the inner side surfaces of the machine housing air inlet and the machine housing air outlet in a lining manner; and the structure, performance and effect of the energy-gathering heat generator are the same as those of the energy-gathering heat generator on the side wall of the machine housing inner-side channel.
According to the invention, no matter to the energy-gathering heat generator on the side wall of the machine housing inner-side channel or the energy-gathering heat generator on the impeller and on the blade, as well as the energy-gathering heat generator inside the air inlet and the air outlet of the machine housing, the outer surface of the heat generator transmission protective cover can be configured as a smooth and flat structure, but can also be configured as an uneven structure. In the case of the outer surface of the heat generator transmission protective cover is smooth and flat, high-pressure high-speed air flow can smoothly pass through the surface of the heat generator transmission protective cover during operation, and intense internal layer friction can be caused in the heat generator friction heat-generation body to generate heat. In the case of the outer surface of the heat generator transmission protective cover is an uneven structure, great resistance can be generated against high-pressure high-speed air flow during operation. Heat can be generated by friction, and the temperature of the gas in the machine housing inner-side channel is increased.
The outer side surface of the heat generator friction heat-generation body of the energy-gathering heat generator can be configured as a flat structure or an uneven structure, and in the case of the outer side surface of the heat generator friction heat-generation body is configured as an uneven structure, the convex part (the convex part is called a convex point of the heat generator friction heat-generation body, the concave part is called a concave point of the heat generator friction heat-generation body) is too high and too large, and the surface of the convex point is also uneven, and the heat generator transmission protective cover is also in an uneven structure corresponding thereto, during operation, the whole energy-gathering heat generator can generate more heat by means of four kind of intense friction of the heat generator transmission protective cover, interior of the heat generator friction heat-generation body, interior and exterior of the convex point of the heat generator friction heat-generation body, so that the temperature of gas can be increased further.
In summary, the high-temperature hot air blower capable of gathering energy and generating heat can fully and effectively decompress and decelerate the high-pressure high-speed air flow produced by the impeller of the blower to generate heat to form high-temperature hot air by virtue of the energy-gathering heat generator and the damping function of the heat generator friction heat-generation body of the energy-gathering heat generator.
Noise of the blower can be sufficiently and effectively reduced by utilizing the damping function of the friction heat-generator, sound waves of the noise excited during the hot air blower works have certain mechanical energy, when the sound waves impact the energy-gathering heat generator, friction heat generated inside the energy-gathering heat generator (the heat generator friction heat-generation body of the energy-gathering heat generator) can be facilitated, with the mechanical energy converted into thermal energy, so that part of the sound waves can be reduced or eliminated, and as a result, the noise is reduced or eliminated.
In addition, the heat generator transmission protective cover of the energy-gathering heat generator is tough and resilient, when impacted by the high-pressure high-speed air flow, the heat generator transmission protective cover can effectively reduce the pressure of the heat generator friction heat-generation body and enable the air flow to continue in one direction under decompression and deceleration, reverse air flow due to collision can not be generated, and thus noise due to collision and friction between the reverse and forward air flow can be avoided, that is, the energy-gathering heat generator can reduce the probability of noise produced by high-pressure high-speed air flow, and controls the blower to produce only a limited and low level of noise.
The energy-gathering heat generator can not only control the blower to produce limited and low level of noise, but also further absorb and reduce the limited and low level of noise caused by air flow of the blower to even lower noise.
In summary, the energy-gathering heat generator can not only enable the blower to generate heat, but also enable the blower to reduce noise; an improved energy-saving and emission-reducing high-temperature hot air blower capable of gathering energy and generating heat product can be developed by betterment of the energy-gathering heat generator technology.
According to the invention, the energy-gathering heat generator can be respectively or simultaneously arranged on the side wall of the machine housing inner-side channel, on the blade disc, on the blade, in the machine housing air inlet, in the machine housing air outlet and other flow channel parts.
According to the invention, if a wind-shielding heat generator is disposed in the flow channel inside the machine housing, and the energy-gathering heat generator is disposed on the wind-shielding heat generator (the side wall of the energy-gathering heat generator is in fit connection with the side wall of the wind-shielding heat generator or wraps the wind-shielding heat generator), the high-pressure high-speed air flow can generate better friction effect upon collision on the energy-gathering heat generator, generate more heat, produce high-temperature hot air with higher temperature, and simultaneously effectively reduce noise.
In order to enable the heat generated by the heat generator friction heat-generation body of the energy-gathering heat generator to be transferred to the gas in the machine housing inner-side channel as soon as possible, a special heat conducting element (metal wire or metal sheet with good heat transfer performance and the like) can also be provided inside the heat generator friction heat-generation body. The heat conducting element is also directly connected with the heat generator transmission protective cover, and the heat generator transmission protective cover absorbs the heat generated by the heat generator friction heat-generation body through the special heat conducting element and then transmits the heat to the gas in the machine housing inner-side channel.
1 machine housing, 2 machine housing air inlet, 3 machine housing air outlet, 4 impeller, 5 impeller air inlet, 6 impeller air outlet, 7 blade, 8 blade disc, 9 impeller shaft sleeve, 10 impeller inner-side channel, 11 machine housing inner-side channel, 12 side wall of machine housing inner-side channel, 13 energy-gathering heat generator, 14 heat generator transmission protective cover, 15 heat generator friction heat-generation body, 16 heat generator heat-insulation isolation wall, 17 energy-gathering heat generator convex part, 18 energy-gathering heat generator concave part, 19 wind-shielding heat generator, 20 special heat conducting element, 21 motor.
Hereinafter, the technical solution of the present invention will be described in detail with reference to the accompanying drawings:
With reference to
The machine housing of this Embodiment is of a general low-heat and large-flow structure, the axial size of the machine housing is large, the calibers of the air inlet 2 and the air outlet 3 of the machine housing are large, and the shaft of the motor 21 is connected with the impeller shaft sleeve 9.
During operation, the motor 21 drives the impeller 4 to rotate at a high speed, the impeller which rotates at a high speed draws in cold air through the impeller air inlet 5 and the machine housing air inlet 2 to produce high-pressure high-speed air flow, and the high-pressure high-speed air flow is discharged from the impeller air outlet 6 to the machine housing inner-side channel 11. During flow process, the high-pressure high-speed air flow in the machine housing inner-side channel 11 continuously impacts the heat generator transmission protective cover 14 of the energy-gathering heat generators 13 on the radial side wall 12 of the machine housing inner-side channel and the axial side wall 12 of the machine housing inner-side channel, so that the heat generator transmission protective cover 14 presses against the heat generator friction heat-generation body 15 and transfers pressure power energy to the heat generator friction heat-generation body 15; and the heat generator friction heat-generation body 15 absorbs the pressure power mechanical energy, and converts it to thermal energy by intense internal layer friction to generate heat. By virtue of the heat insulation effect of the heat generator heat-insulation isolation wall 16, the heat generated by the heat generator friction heat-generation body will not be transferred to the side wall 12 of the machine housing inner-side channel to be dissipated outside the machine housing. The heat generated by the heat generator friction heat-generation body 15 is transferred to the high-pressure high-speed gas in the machine housing inner-side channel 11 through the heat generator transmission protective cover 14, so that the temperature of the high-temperature high-speed gas is increased to produce high-temperature hot air, and the high-temperature hot air is discharged out of the machine housing through the air outlet 3 of the machine housing to be used for other purposes.
In this Embodiment, the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 is loose, soft and elastic, the heat generator friction heat-generation body 15 is soft, elastic and thick, so when the heat generator transmission protective cover 14 is impacted and collided by high-pressure high-speed air flow, the heat generator transmission protective cover 14 continuously presses the heat generator friction heat-generation body 15 which contracts and rubs against the heat generator transmission protective cover 14, so that the high-speed air flow can be facilitated to continue in one direction under decompression and deceleration, reverse air flow due to collision and friction would not rise from the unidirectional air flow, and thus noise due to collision and friction between the reverse and forward air flow can be avoided. On the other hand, because the heat generator friction heat-generation body has a good damping function, the noise sound wave excited by the high-pressure high-speed air flow originally has certain mechanical energy, and when the noise sound wave impacts the soft and elastic heat generator transmission protective cover 14, the noise sound wave mechanical energy is transmitted through the heat generator transmission protective cover 14 to the heat generator friction heat-generation body 15, so that the heat generator friction heat-generation body 15 generates heat by internal layer friction, with the mechanical energy converted to thermal energy; part of the noise sound waves are thereby reduced and eliminated, resulting in reduced noise by using the machine.
In this Embodiment, by means of the energy-gathering and heat-generating function of the energy-gathering heat generator 13 through friction, required high-temperature hot air can be produced, with good processing effect, high efficiency, low noise, and being beneficial to environmental protection.
This Embodiment is suitable for manufacturing the low-pressure high-flow high-temperature hot air blower capable of gathering energy and generating heat for heating, greenhouse cultivation and other applications.
For simplicity and convenience in processing, in this Embodiment, the energy-gathering heat generator 13 can be directly made of a soft rubber plate, the bottom side of the soft rubber plate is coated with a layer of high-temperature-resistant heat-insulation liquid glue or paint, and is adhered with the side wall of the machine housing inner-side channel through the liquid glue or paint, the liquid glue or paint itself is the heat generator heat-insulation isolation wall 15. The upper surface of the thick rubber plate is coated with a layer of liquid rubber or paint with good high temperature resistance and heat conductivity, or the thick rubber plate is covered by a layer of stainless steel mesh, and the layer of liquid rubber paint or stainless steel mesh is the heat generator transmission protective cover 14.
With reference to
The blade 7 is wrapped by the energy-gathering heat generator 13, the energy-gathering heat generator 13 on the blade disc is adhered to the inner side surface of the blade disc, and the energy-gathering heat generator 13 on the blade and the energy-gathering heat generator 13 on the blade disc form a new impeller inner-side channel 10.
During operation, the high-pressure high-speed air flow produced by the blades 7 at any time impacts the energy-gathering heat generator 13 on the blades 7 and on the blade disc 8 at any time and any place; heat is generated in the whole inner-side channel 10 of the impeller at any time and any place to increase the gas temperature and form high-pressure high-speed high-temperature hot air; the high-pressure high-speed high-temperature hot air is discharged to the machine housing inner-side channel 11 through the impeller air outlet 6, and then impacts the energy-gathering heat generator 13 on the radial side wall and axial side wall of the inner-side channel, so that internal layer friction of the energy-gathering heat generator 13 is caused to generate heat, and the gas temperature is further increased.
In this Embodiment, the high-speed gas produced by the impeller flows through the impeller inner-side channel 10 and the machine housing inner wall flow channel 11 for twice friction, decompression and deceleration to generate heat, so more heat is generated, and the gas temperature is increased further.
As in Embodiment 1, by virtue of the damping effect of the heat generator transmission protective cover 14 and of the heat generator friction heat-generation body 15 of the energy-gathering heat generator 13, the noise generated in the operation process of this Embodiment is reduced with no noise pollution.

The high-temperature hot air is discharged to the impeller 4, processed by the impeller 4 to increase pressure and speed, and then discharged to the machine housing inner-side channel 11 to impact the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 on the side wall of the machine housing inner-side channel, so that the uneven heat generator transmission protective cover 14 generates heat, (intense friction occurs between artificial filaments and wool filaments, and between wool filaments and gas), the heat generator friction heat-generation body 15 generates heat by intense friction, and thus the temperature of the gas is increased. The high-temperature hot air enters the air outlet 3 of the machine housing, subjected to intense friction of the heat generator friction heat-generation body 15 of the energy-gathering heat generator 13 in the air outlet 3 of the machine housing to generate heat, thereby increasing the temperature of the air further, forms high-temperature hot air with higher temperature which is then discharged from the machine body to serve other purposes.
In the operation process of this Embodiment, the cold air entering the machine body passes through the heat generator transmission protective cover 14 of the energy-gathering heat generators 13 in the machine housing air inlet 2, in the machine housing inner-side channel 11 and in the machine housing air outlet 3, multiplied internal layer friction of the heat generator friction heat-generation body occurs, more heat is generated, and the temperature of the gas is increased higher (>100° C.).
As in Embodiment 1, the noise generated during operation is low and does not cause environmental pollution.
This Embodiment is suitable for manufacturing an ultra-high temperature hot air blower in application.
With reference to

During operation, the high-speed cold air drawn in the machine housing air inlet 2 is processed by the internal layer upper surface of the sponge heat generator friction heat-generation body 15 and the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 in the machine housing air inlet 2 to form high-temperature hot air, the high-temperature hot air is pressurized and accelerated by the impeller to form high-pressure high-speed high-temperature hot air, and the high-pressure high-speed high-temperature hot air enters the machine housing inner-side channel 11, passes through the heat generator friction heat-generation body 15 and the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 on the side wall 12 of the machine housing inner-side channel to process again to generate heat, the high-pressure high-speed hot air also impacts the energy-gathering heat generator 13 on the wind-shielding heat generator 19 in the machine housing inner-side channel 11, subjected to the heat generator friction heat-generation body 15 and the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 on the wind-shielding heat generator 19 to process again to generate heat to form the ultra-high-temperature hot air with higher temperature. The high-pressure high-speed ultra-high-temperature hot air is subjected to once again processing heat generation by passing through the friction heat generation body 15 and the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 in the machine housing air outlet 3 to generate heat, the temperature is further increased, the high-pressure high-speed ultra-high-temperature hot air becomes ultra-high-temperature hot air with even higher temperature which is then discharged out of the machine body for use.
In this Embodiment, the heat generator friction heat-generation body 15 of all the energy-gathering heat generators 13 are made of high-temperature-resistant sponge products, whose damping friction heat-generating effect and sound-reducing effect are better, therefore, more heat is generated, the air temperature increases further (>200° C.) to form ultra-high-temperature hot air with higher temperature; and the noise generated in the operation process of this Embodiment is low, without causing noise pollution.
This Embodiment is suitable for manufacturing an ultra-high temperature hot air blower (>200° C.) for food processing, industrial product processing and the like.
With reference to
During operation, the heat generated by the heat generator friction heat-generation body of the energy-gathering heat generator 13 on the side wall of the machine housing inner-side channel is transferred to the heat generator transmission protective cover, and is then transferred by the heat generator transmission protective cover to the gas in the machine housing inner-side channel 11 rapidly, so that the gas in the machine housing inner-side channel is rapidly heated and becomes high-temperature hot air.
As in Embodiment 1, this Embodiment is suitable for manufacturing a general high-temperature hot air blower for heating and warmth-keeping and growth-facilitating in an ecological greenhouse.
According to the high-temperature hot air blower capable of gathering energy and generating heat of the invention, by means of the energy-gathering heat generator, and by means of the damping function of the heat generator friction heat-generation body of the energy-gathering heat generator, high-pressure high-speed air flow processed by the machine impeller can be fully and effectively decompressed and decelerated to generate heat, and high-temperature hot air is formed. The high-temperature hot air blower capable of gathering energy and generating heat disclosed herein can generate high-temperature hot air, and has the advantages of generating a large amount of hot air having a high hot air pressure, saving energy, having low noise, having multiple functions and a wide usage range, which can satisfy multiple usage demands for high-temperature hot air in production and living by people.
