[0025] Example 1

[0026] As mentioned in the background technology, in order to solve the problems in the prior art, this embodiment provides a condensed water recycling device, comprising:

[0027] The housing 1 has a first space 11 therein and a discharge port is provided on the housing 1. The first space 11 is connected to the outside through the discharge port.

[0028] The heat exchange pipe 2 is provided in the first space 11 and has both ends passing through the shell 1 for circulating the refrigerant;

[0029] The condensation water pipe 3 has one end connected to the evaporator to receive condensation water, and the other end communicates with the first space 11 .

[0030] like Figure 2 As shown, the shell 1 is approximately a cylindrical structure, the first space 11 is the internal space of the shell 1, the heat exchange pipeline 2 is approximately a circular tube structure, is arranged in the first space 11, and both ends pass through the shell 1 respectively, one end is connected with the output end of the condenser, and the other end is connected with the input end of the electronic expansion valve 6, and the condensed water pipe 3 is used to pass the received condensed water into the first space 11; the liquid refrigerant with a temperature of 50°C to 60°C discharged from the output end of the condenser circulates in the heat exchange pipeline 2, and the condensed water with a temperature of 5°C to 10°C discharged from the condensed water pipe circulates in the first space 11. The refrigerant is cooled by the condensed water, and the cooling capacity consumed when the condensed water is generated can be effectively utilized.

[0031] By arranging a heat exchange pipe 2 in the outer shell 1, the two ends of the heat exchange pipe 2 are connected between the condenser and the electronic expansion valve 6, the condensed water received by the condensed water pipe 3 is passed into the first space 11, and the high-temperature refrigerant discharged from the condenser is passed into the heat exchange pipe 2. The high-temperature refrigerant is cooled by using low-temperature condensed water, and the energy in the condensed water can be utilized, thereby effectively reducing the energy consumption of the vehicle air-conditioning during cooling.

[0032] In a preferred embodiment, the condensed water pipe 3 is connected to one end of the housing 1 , and the drain port is opened at an end of the housing 1 away from the condensed water pipe 3 .

[0033] like Figure 1 As shown, the condensate pipe 3 and the discharge port are respectively arranged at both ends of the shell 1, which can effectively increase the flow time of the condensate in the first space 11, thereby allowing the condensate to fully exchange heat with the refrigerant in the heat exchange pipeline 2.

[0034] In a preferred embodiment, the flow direction of the condensed water in the shell 1 is opposite to the flow direction of the refrigerant in the heat exchange pipe 2 .

[0035] like Figure 2 As shown, by making the condensed water in the first space 11 and the refrigerant in the heat exchange pipe 2 flow in the opposite direction, a larger average temperature difference can be achieved between the condensed water and the refrigerant during the heat exchange process, thereby allowing more heat to be transferred between the two.

[0036] In a preferred embodiment, the housing 1 is connected to a first branch pipe 4 , and a free end of the first branch pipe 4 has a discharge port.

[0037] like Figure 1As shown, the first branch pipe 4 is formed by extending from one end of the shell 1 away from the condensate pipe 3. The free end of the first branch pipe 4 has a discharge port. The provision of the first branch pipe 4 facilitates secondary recycling of the condensate by directly connecting the first branch pipe 4.

[0038] In a preferred embodiment, the housing 1 and the heat exchange pipe 2 are coaxially arranged.

[0039] like Figure 2 As shown, the shell 1 and the heat exchange pipe 2 are coaxially arranged, that is, the heat exchange pipe 2 is arranged in the middle of the first space 11, so that the condensed water can be evenly contacted with the outer wall of the heat exchange pipe 2 in the first space 11, thereby improving thermal efficiency; in other embodiments of the present application, the heat exchange pipe 2 can also adopt a spiral structure or a continuously curved structure, which can effectively increase the contact area between the first space 11 and the heat exchange pipe 2, thereby improving the heat exchange effect between the condensed water and the refrigerant.

[0040] Example 2

[0041] This embodiment provides an air-conditioning box assembly, including a condensed water recovery and utilization device as described in Example 1, and also including an electronic expansion valve 6, the input end of the electronic expansion valve 6 is connected to the heat exchange pipeline 2, and the output end thereof is connected to the evaporator.

[0042] In a preferred embodiment, the output end of the evaporator is connected to the compressor through the first pipeline 7; the heat exchange pipeline 2 and the first pipeline 7 are detachably connected.

[0043] like Figure 3 and 4 As shown, the air-conditioning box assembly also includes a box body 5, an evaporator is provided in the box body 5, the input end of the electronic expansion valve 6 is connected to the heat exchange pipeline 2, and its output end is connected to the evaporator, and the output end of the evaporator is connected to the first pipeline 7, which is used to connect to the compressor. The outer shell 1 is fixed to the first pipeline 7 by a snap.

[0044] Working principle: When in use, the two ends of the heat exchange pipe 2 are respectively connected to the condenser output end and the electronic expansion valve 6 input end, and the condensate pipe 3 is connected to the evaporator to receive the condensate; the condensate discharged from the evaporator enters the first space 11 through the condensate pipe 3, and at the same time, the refrigerant enters the heat exchange pipe 2 from the end of the heat exchange pipe 2 away from the condensate pipe 3. After the condensate and the refrigerant exchange heat, the condensate that absorbs heat is discharged out of the vehicle through the discharge port of the first branch pipe 4, and the refrigerant that releases heat enters the electronic expansion valve 6 through the end of the heat exchange pipe 2 close to the condensate pipe 3.

[0045] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and core ideas of this application. The above is only the preferred implementation method of this application. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can also make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the scope of protection of this application.
