20220163229
This application claims priority to Chinese Patent Application No. 202022732306.X, filed Nov. 23, 2020, and all the benefits accruing therefrom under 35 U.S.C. § 119, the contents of which in its entirety are herein incorporated by reference.
This disclosure relates to the technical field of air conditioning devices, especially to an electric cabinet of an air conditioner and an air conditioner with the electric cabinet of an air conditioner.
When an air-conditioning device is running for a long time, electronic components inside the electric cabinet will generate heat. When the heat cannot be dissipated or the heat dissipation is not good, it will seriously affect the normal operation of the machine and the service life of the electronic components. Moreover, air-conditioning equipment will also be installed outdoors, facing the problem of waterproof and rainproof. In conventional compact electric cabinets, some only consider heat dissipation, and some are able to perform heat dissipation and rain protection at the same time. However, the heat dissipation channel is small, resulting in poor heat dissipation; and the design of an air duct structure is defective. In order to prevent rainwater from entering the inside of the electric cabinet, air vents are designed to be misplaced, which causes the air duct of the box body to be blocked, affecting the heat dissipation efficiency of the electric cabinet body.
A main purpose of this disclosure is to provide an electric cabinet of an air conditioner and an air conditioner having the same, which solves the technical problem of low heat dissipation efficiency while preventing rain in the prior art.
This disclosure provides an electric cabinet of an air conditioner, comprising a box body, a bottom plate, and a ventilation cover plate, wherein the bottom plate is installed at the bottom of the box body, the ventilation cover plate is installed at the bottom of the bottom plate and forms a cavity with the bottom plate; air vents are provided on the bottom plate, shutters are provided on the ventilation cover plate, and the shutters are aligned with the air vents on the bottom plate.
Further, there are a plurality of air vents, and the plurality of air vents are closely arranged on the bottom plate.
Further, sizes and shapes of the air vents are different from each other.
Further, slats of the shutters are opened downwards.
Further, air inlets and air outlets are formed between the slats of the shutters and the ventilation cover plate, and the air outlets are aligned with the air vents.
Further, the air outlets are communicated with the cavity.
Further, there are a plurality of shutters, and the plurality of shutters are arranged in an array on the ventilation cover plate.
Further, the air outlets of the shutters are each aligned with at least one air vent.
Further, the slats of the plurality of shutters are opened in the same direction.
This disclosure further provides an air conditioner comprising the electric cabinet of an air conditioner.
In an electric cabinet of an air conditioner and an air conditioner having the same provided in this disclosure, air vents are arranged on a bottom plate, shutters are arranged on a ventilation cover plate, a cavity is formed between the bottom plate and the ventilation cover plate, and the air vents are aligned with the shutters, which can reduce air duct resistance and accelerate heat dissipation inside the electronic cabinet body. The shutters can also achieve the purpose of waterproof and rainproof while improving the ventilation and heat dissipation effect inside the electric cabinet.
In the drawings, box body 1, bottom plate 2, air vent 21, ventilation cover plate 3, shutter 31, air inlet 311, air outlet 312, cavity 4 are shown.
The realization of the purpose, functional characteristics, and advantages of this disclosure will be further described in conjunction with the embodiments and with reference to the accompanying drawings.
It should be understood that the specific embodiments described here are only used to explain this disclosure and are not used to limit this disclosure.
With reference to
Box body 1 is used to install and electrically control main electronic components, circuit boards, etc.; bottom plate 2 is used for air intake and protection; and ventilation cover plate 3 is mainly used for ventilation, heat dissipation, and rain prevention of the electric cabinet.
Shutters 31 are aligned with air vents 21 on bottom plate 2. It may be understood that after entering cavity 4 from shutters 31, wind may directly flow out through air vents 21 since shutters 31 are aligned with air vents 21, thereby reducing air duct resistance and improving heat dissipation efficiency of the electric cabinet.
It should be noted that the electrical components in the electric cabinet are compactly arranged and generate a large amount of heat. Electrical components under high temperature have great safety risks. After ventilation, the heat of electrical components can be taken away in time to prevent the electrical components from being damaged under high temperature. As shown in
In an embodiment, there are a plurality of air vents 21, and the plurality of air vents 21 are closely arranged on bottom plate 2.
After wind enters cavity 4 from shutters 31, it flows out from the plurality of air vents 21 arranged on bottom plate 2. The more the air vents 21 are, the faster the wind flows out, which can further improve the heat dissipation efficiency of the electric cabinet, making the ventilation and heat dissipation effect of the electric cabinet better.
In an embodiment, sizes and shapes of air vents 21 are different from each other.
There are a plurality of air vents 21 with different sizes and shapes. Air vents 21 can be set larger in some parts where strong heat dissipation is required, so as to speed up wind from air vents 21 into box body 1 and improve the heat dissipation efficiency of the electric cabinet.
In an embodiment, slats of shutters 31 are opened downwards.
As shown in
In an embodiment, air inlets 311 and air outlets 312 are formed between the slats of shutters 31 and ventilation cover plate 3, and air outlets 312 are aligned with air vents 21.
As shown in
In an embodiment, air outlets 312 are communicated with cavity 4.
Air outlets 312 on shutters 31 are communicated with cavity 4, thus wind enters from air inlets 311 and flows directly into cavity 4, and then flows into box body 1 through air vents 21 to conduct heat dissipation for the electrical components in box body 1.
In an embodiment, there are a plurality of shutters 31, and the plurality of shutters 31 are arranged in an array on ventilation cover plate 3.
As shown in
In an embodiment, air outlets 312 of shutters 31 are each aligned with at least one air vent 21.
Hence, all the wind entering from shutters 31 can flow into box body 1 directly through air vents 21 without turning in cavity 4 to conduct heat dissipation for the components in box body 1 and improve the heat dissipation efficiency.
In an embodiment, the slats of the plurality of shutters 31 are opened in the same direction.
As shown in
This disclosure further provides an air conditioner, and the air conditioner is provided with the above electric cabinet of an air conditioner. Since the air conditioner has the above electric cabinet of an air conditioner, and the electric cabinet of an air conditioner has above advantages, by setting the electric cabinet of an air conditioner, the air conditioner has corresponding advantages. Therefore, the air conditioner of this embodiment has good ventilation and heat dissipation effects, good electric control and rainproof effects, low air duct resistance, and high electric cabinet heat dissipation efficiency.
It should be noted that the terms “comprise,” “include,” or any other variants thereof herein are intended to cover non-exclusive inclusion, thus a process, a device, an article, or a method that includes a series of elements not only includes those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such a process, device, article, or method. If there are no more restrictions, the element defined by the sentence “comprising a . . . ” does not exclude the existence of other identical elements in the process, device, article, or method that includes the element.
The above description is only preferred embodiments of this disclosure, and do not limit the patent scope of this disclosure. Any equivalent structure or equivalent process transformation made by using the content of the description and drawings of this disclosure, or directly or indirectly used in other related technical fields, are similarly included in the scope of patent protection of this disclosure.
