DETAILED DESCRIPTION

[0027] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0028] like Figures 1 to 6 As shown, the present embodiment provides a tunnel-type evaporative condenser 30 assembly, including a pipe 10, in which a first channel 11 extending up and down is arranged, the first channel 11 is open at the top and the bottom, and its side walls are blocked, so that the assembly as a whole is similar to the form of a tunnel, a fan 70 is connected to the top of the first channel 11, and the fan 70 is used to blow air into the first channel 11 and make the air flow downward, an evaporator 20 is arranged in the first channel 11, air enters the first channel 11 and flows through the evaporator 20, and the evaporator 20 contains a refrigerant, and the refrigerant can cool the air flowing through the evaporator 20 and liquefy the moisture in the air to form liquid water; in the present invention, the first channel 11 adopts a longer tunnel form, under the condition of the same wind flux of the inflowing air and the same outer surface area of ​​the refrigeration pipe 21, the inflowing air has a longer contact time with the refrigeration pipe 21, and the moisture in the air can be more fully condensed into liquid water, thereby improving the efficiency of preparing liquid water.

[0029] One group of evaporators 20 is provided, or multiple groups of evaporators 20 are provided, and the multiple groups of evaporators 20 are vertically arranged in the first channel 11, and between two adjacent groups of evaporators 20, the cooling temperature of the next group of evaporators 20 is lower than the cooling temperature of the previous group of evaporators 20; when there are multiple groups of evaporators 20 in the present invention, the cooling temperature of the rear evaporator 20 is set to be lower than the cooling temperature of the front evaporator 20, and the air flows through all the evaporators 20 in turn. Under the joint action of the multiple groups of evaporators 20, liquid water is more fully condensed, and the water production effect is better under the same total refrigeration energy consumption.

[0030] The evaporator 20 includes a refrigeration pipe 21, and the refrigeration pipe 21 is filled with the refrigerant. The refrigerant is in liquid state, and the temperature of the liquid refrigerant is lower than the temperature of the air blown into the first channel 11 by the fan 70. When the air flows through the refrigeration pipe 21, the liquid refrigerant absorbs the heat of the air and then vaporizes to cool the air, and at the same time, the moisture in the air is liquefied to form liquid water. A condenser 30 is arranged below the evaporator 20, and the air flowing through the evaporator 20 can flow to the condenser 30. The condenser 30 includes a condensing pipe The condensing pipe 31 and the refrigeration pipe 21 are connected to each other. The liquid refrigerant is vaporized in the refrigeration pipe 21 to form a gaseous refrigerant and flows into the condensing pipe 31. The temperature of the air after being cooled by the evaporator 20 is lower than the temperature of the condenser 30. When the air flows through the condensing pipe 31, the temperature of the condenser 30 is reduced, so that the refrigerant inside the condenser 30 is liquefied. After being liquefied, the refrigerant flows into the refrigeration pipe 21 to evaporate, thereby cooling the air flowing through the evaporator 20 and the liquefied water vapor to form liquid water.

[0031] The channel of the condenser 30 is in a tunnel-like form, which can increase the total time of air cooling the condenser 30 and improve the heat dissipation efficiency.

[0032] The condensing pipes 31 in the condenser 30 extend horizontally and are arranged in an array up and down, and the condensing pipes 31 are arranged in multiple groups in parallel, which can increase the flow rate of the refrigerant in the pipes 31 of the condenser 30 to improve the heat dissipation efficiency;

[0033] Specifically, the refrigeration pipe 21 has an input port and an output port, the condensation pipe 31 has an input port and an output port, the output port of the condensation pipe 31 is connected to the input port of the refrigeration pipe 21 through a pipe, and the input port of the condensation pipe 31 is connected to the output port of the refrigeration pipe 21, so that the refrigeration pipe 21 and the condensation pipe 32 are circulated and connected, an expansion valve is provided between the output port of the condensation pipe 31 and the input port of the refrigeration pipe 21, and a compressor is provided between the output port of the refrigeration pipe 21 and the input port of the condensation pipe 31. The connection arrangement and the use principle of the evaporator 20, the compressor, the condenser 30 and the expansion valve are all prior art and will not be described in detail here.

[0034] Specifically, after the liquid refrigerant in the refrigeration pipe 21 absorbs heat and vaporizes, it enters the condensation pipe 31 through the pipe and the compressor to form a gaseous refrigerant. After the gaseous refrigerant in the condensation pipe 31 releases heat and liquefies, it enters the refrigeration pipe 21 through the pipe and the expansion valve to form a liquid refrigerant. Therefore, the refrigerant is circulated between the refrigeration pipe 21 and the condensation pipe 31. Specifically, the refrigerant entering the refrigeration pipe 21 through the expansion valve is a low-pressure liquid refrigerant suitable for evaporation in the evaporator 20, and the refrigerant entering the condensation pipe 31 through the compressor is a high-temperature and high-pressure refrigerant vapor. It can be understood that the specific structure of the evaporator 20 is the prior art, and the refrigeration pipe 21, the fin 60, and the input port and the output port of the refrigeration pipe 21 described below are all prior art, which will not be described in detail here. It can be understood that the specific structure of the condenser 30 is the prior art, and the condensation pipe 31, the fin 60, and the input port and the output port of the condensation pipe 31 described below are all prior art, which will not be described in detail here.

[0035] Specifically, after the air flows through the evaporator 20, its temperature decreases, and the air then flows into the condenser 30, which can dissipate heat from the condenser 30 and improve energy efficiency. It can be understood that the refrigerants are all commonly used refrigerants in the prior art and will not be described in detail here.

[0036] like Figures 1 to 3 As shown, in one embodiment, the evaporator 20 and the condenser 30 are both in the first channel 11, and the evaporator 20 is located directly above the condenser 30;

[0037] like Figure 4 As shown, further, a water receiving member 40 is provided between the evaporator 20 and the condenser 30. The water receiving member is in a tapered shape with a downward tip. A water receiving groove 41 is provided in the water receiving member 40. The water receiving groove 41 is also in a tapered shape with a downward tip. The water receiving groove 41 is used to receive liquid water from the evaporator 20. A water outlet 42 is provided below the side wall of the water receiving groove 41. The water outlet 42 is connected to a water outlet pipe 43. The water outlet pipe 43 extends to the outside of the first channel 11 through the gap between the condenser 30 and the first channel, so that the water in the water receiving groove 41 flows to the first channel 11. Outside; it can be understood that the reason why the water outlet 42 is arranged below the side wall of the water receiving tank 41 instead of at the bottom of the water receiving tank 41 is that it plays the role of depositing impurities: the liquid water formed by the liquefaction of air contains impurities, and the liquid water will not flow out from the water outlet immediately when it falls into the water receiving tank 41, but will be first stored at the bottom of the water receiving tank 41, so that the impurities in the liquid water are deposited at the bottom of the water receiving tank 41, and when the liquid level reaches the water outlet 42, it will flow into the water outlet pipe 43, and flow out to the outside of the first channel 11 through the water outlet pipe 43.

[0038] like Figure 4As shown, a guide member 50 is arranged above the water receiving member 40. The guide member 50 is in a cone shape with the tip pointing upward. The bottom of the guide member 50 and the top of the water receiving member 40 are connected together by a connecting member 80, and the guide member 50 and the water receiving member 40 are connected to the first channel 11 through the connecting member 80. There is a gap between the guide member 50, the water receiving member 40 and the first channel 11. The conical guide member 50 can guide the air flowing through the evaporator 20 to the gap between the guide member 50, the water receiving member 40 and the first channel 11, so that the air flows toward the condenser 30 after passing through the gap between the guide member 50, the water receiving member 40 and the inner wall of the first channel 11, and the conical guide member 50 can prevent the air flowing downward through the evaporator 20 from flowing upward. A notch groove 51 is also arranged at the bottom of the side wall of the guide member 50, and water falling on the surface of the guide member 50 can flow into the water receiving groove 41 through the notch groove 51.

[0039] Preferably, in this embodiment, the water receiving member 40 and the flow guide member 50 are both pyramidal, and there is a gap between the connection between the two and the first channel 11. The flow guide member 50 guides the air passing through the evaporator 20 to the gap between it and the first channel 11. After passing through the gap, the air flows into the water receiving member 40, and the water receiving member 40 can guide the air to the center of the first channel 11; preferably, the water receiving groove 41 is also pyramidal.

[0040] like Figures 5 and 6 As shown, in another embodiment, the first channel 11 is bifurcated below the evaporator 20 to form a second channel 12 and a third channel 13, the second channel 12 extends along the extension direction of the first channel 11, and the third channel 13 is located beside the second channel 12. The first channel 11, the second channel 12 and the second channel 12 are interconnected, the evaporator 20 is located in the first channel 11, and the condenser 30 is arranged at the lower end opening of the third channel 13. The air flowing through the evaporator 20 flows into the third channel 13, and then flows from the lower end of the third channel 13 to the condenser 30.

[0041] Furthermore, a water receiving member 40 is provided in the second channel 12, directly below the evaporator 20. The water receiving member 40 is located below the connection between the third channel 13 and the first channel 11 and the second channel 12. The water receiving member 40 has a water receiving groove 41, which is used to receive liquid water from the evaporator 20. A water outlet 42 is provided at the bottom of the water receiving member 40, and the water outlet 42 is connected to the water receiving groove 41. The second channel 12 below the water receiving member 40 forms a water receiving space 14, and the water receiving space 14 is used to place a water receiving bucket.

[0042] Preferably, in this embodiment, the water receiving member 40 is in the shape of a prism, the upper bottom surface of the prism is the bottom of the water receiving member 40, and the top edge of the water receiving member 40 is in close contact with the inner wall of the second channel 12. Preferably, the water receiving groove 41 is also in the shape of a prism.

[0043] The present invention also provides a method for preparing water using a tunnel type evaporative condenser 30 assembly, using the above evaporative condenser 30 assembly, comprising the following steps:

[0044] S10: Turn on the fan 70, use the fan 70 to blow air into the first channel 11, let the blown air flow through all the evaporators 20, use the refrigerant in the evaporator 20 to gasify, thereby absorbing the heat of the air, lowering the air temperature, and liquefying the water vapor in the air to form liquid water;

[0045] S20 : ​​The air flowing through the evaporator 20 continues to flow downward, and then flows through the condenser 30 to cool and liquefy the gaseous refrigerant in the condensation pipe 31 , thereby dissipating heat from the condenser 30 .

[0046] The directional terms mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.
