This application is based on and claims the benefit of priority from Chinese Patent Application No. 2020107438826, filed on 29 Jul. 2020, the entirety of which is incorporated by reference herein.
The present disclosure relates to the technical field of refrigeration devices, and in particular, to a cooling pipe system.
Existing manual refrigeration technologies, no matter steam compression refrigeration, steam absorption refrigeration, steam jet refrigeration, adsorption refrigeration, thermoelectric refrigeration, magnetic refrigeration, or acoustic refrigeration, all need to use an electric energy, heat energy, or solar energy auxiliary heat absorber, and the cost is high. However, natural refrigeration technologies, such as air cooling or water cooling, are limited by air temperature or water temperature in natural world, so that the refrigeration temperature thereof is necessarily higher than the air temperature and water temperature, and a refrigeration effect is limited.
The present disclosure aims at solving at least one of technical problems existing in the prior art. With this regard, the present disclosure provides a cooling pipe system which water for evaporation by heat absorption to implement refrigeration, thereby having low cost. Moreover, the refrigeration temperature of the system is lower than the air temperature and water temperature, thereby achieving an excellent refrigeration effect.
A cooling pipe system according an embodiment of the present disclosure includes an evaporation pipe slantly arranged, an input end of the evaporation pipe being higher than an output end of the evaporation pipe; a water inlet pipe, an output end of the water inlet pipe being connected to the input end of the evaporation pipe, the water inlet pipe being connected to a three-way valve, and the three-way valve being used for introducing low molecular weight gas into the evaporation pipe; and a water removal assembly, located below the evaporation pipe and having a water sealing cavity, the output end of the evaporation pipe being connected to the water sealing cavity by means of a recovery pipe, the water sealing cavity being connected to a first pipeline extending upwards and communicated with the input end of the evaporation pipe, a lower end of the first pipeline being connected to a molecular sieve for preventing water vapor from passing through, and the water removal assembly being configured for absorbing the water vapor.
The technical solution above at least has the following beneficial effects. By extracting air in the evaporation pipe from the three-way valve to form vacuum and filling low molecular weight gas into the evaporation pipe, a partial pressure of the water vapor in the evaporation pipe being zero, and then providing by the water inlet pipe liquid water into the evaporation pipe, the liquid water can absorb heat to be evaporated as the partial pressure of the water vapor in the evaporation pipe is zero, and exchange heat with ambient air thereof by means of the evaporation pipe, so as to implement the refrigeration effect for the ambient air. Since the evaporation pipe is slantly arranged towards the output end, the liquid water flows towards the output end of the evaporation pipe while continuously absorbing heat for evaporation to continue refrigeration for the ambient air. After the water is evaporated, the volume of gas in the evaporation pipe is expanded, and the pressure is increased, driving the gas to move towards the water sealing cavity by means of the recovery pipe. After the gas reaches the water sealing cavity, the water vapor gradually trends from an unsaturated state to a supersaturated state. Redundant water vapor is condensed into liquid water in the water sealing cavity. The low molecular weight gas then moves upwards by means of the molecular sieve and the first pipeline for executing a next refrigeration circulation, implementing continuous refrigeration. In this way, refrigeration can be achieved without using the electric energy, solar energy, heat energy, and the like, which has a low cost. Moreover, the refrigeration temperature is lower than the air temperature and water temperature, thereby having an excellent refrigeration effect.

Referring to
When the cooling pipe system operates, air in the evaporation pipe 100 is first extracted by the three-way valve 210 to form vacuum, then the evaporation pipe 100 is filled with helium or hydrogen. The intensity of pressure of helium or hydrogen is set as one atmospheric pressure, and a partial pressure of the water vapor in the evaporation pipe 100 is zero. The water inlet pipe 200 provides liquid water into the evaporation pipe 100. According to the national water supply code, the pressure of the liquid water is greater than one atmospheric pressure. The liquid water absorbs heat to be evaporated as the partial pressure of the water vapor in the evaporation pipe 100 is zero, and exchanges heat with ambient air thereof by means of the evaporation pipe 100, so as to implement the refrigeration effect for the ambient air. Since the evaporation pipe 100 is slantly arranged, the liquid water flows towards the output end of the evaporation pipe 100 and continuously absorbs heat for evaporation to continue refrigeration for the ambient air. After the water is evaporated, the volume of mixed gases of helium and water vapor (or mixed gases of hydrogen and water vapor) in the evaporation pipe 100 is expanded, and the pressure is increased, driving the mixed gases to move towards the recovery pipe 110 and reach the first water sealing cavity 321. The water vapor in the mixed gases in the first water sealing cavity 321 gradually trends from an unsaturated state to a supersaturated state. Redundant water vapor is condensed into liquid water in the first water sealing cavity 321. The liquid water exchanges heat with the outside by means of the upper opening 331 of the second water tank 330, for volatilization to dissipate heat. The low molecular weight gas in the first water sealing cavity 321 then moves upwards by means of the molecular sieve 311 and the first pipeline 310 and enters the evaporation pipe 100 for executing a next refrigeration circulation, implementing continuous refrigeration. In this way, refrigeration can be achieved without using the electric energy, solar energy, heat energy, and the like, which has a low cost. Moreover, the refrigeration temperature is lower than the air temperature and water temperature, thereby achieving an excellent refrigeration effect.
In some other embodiments, referring to
In some embodiments, an inclined angle of the input end of the evaporation pipe 100 towards the output end of the evaporation pipe 100 is 2° to 10°, and preferably, 2°. This inclined angle enables the liquid water to gradually flow towards the output end of the evaporation pipe 100 and slow down the flow of the liquid water to avoid missing evaporation due to rapid flowing of the liquid water. The entire evaporation pipe 100 is provided with the liquid water for heat absorption and evaporation, so that the evaporation pipe 100 fully exchanges heat with the ambient air, to ensure the refrigeration effect.
