[0025] With the development of new energy vehicles, how to improve charging efficiency and ensure charging safety has become an increasingly important issue for people to solve. In the process of cooling the charging gun, the existing charging pile has low cooling efficiency and poor cooling effect for the cooling medium, which may easily bring safety hazards.

[0026] In view of this, the utility model proposes a cooling system, including a first circulation loop and a second circulation loop, wherein the first circulation loop and the second circulation loop share a heat exchanger, so that the first circulation loop is used to cool down the second circulation loop. In this way, the cooling efficiency is improved and the structure of the cooling system is simplified. At the same time, the first circulation loop uses a compressor and a condenser to cool down the first cooling medium in the first circulation loop, further improving the cooling effect.

[0027] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0028] Please refer to Figure 1As shown, the utility model proposes a cooling system 100, including a compressor 11, a condenser 12, a first pump 13, a charging gun 21, a second pump 22 and a heat exchanger 30; the compressor 11, the condenser 12, the first pump 13 and the heat exchanger 30 are connected through a first cable 14 to form a first circulation loop 10; the charging gun 21, the second pump 22 and the heat exchanger 30 are connected through a second cable 23 to form a second circulation loop 20; a first cooling medium is provided in the first circulation loop 10, and a second cooling medium is provided in the second circulation loop 20; in the heat exchanger 30, the first circulation loop 10 absorbs heat in the second circulation loop 20.

[0029] Understandable, such as Figure 1 As shown, the cooling system 100 includes a first circulation loop 10 and a second circulation loop 20. In the first circulation loop 10, the compressor 11, the condenser 12, the first pump 13 and the transducer are connected through the first cable 14, and the first cooling medium is passed through the first cable 14. The compressor 11 is used to compress the first cooling medium, and the compressed first cooling medium flows into the condenser 12. The condenser 12 can condense the high-pressure first cooling medium. The condensed first cooling medium is driven by the first pump 13 and flows toward the heat exchanger 30, where it absorbs the heat in the second circulation loop 20, and then the first cooling medium flows back into the compressor 11. In the second circulation loop 20, the charging gun 21, the second pump 22 and the heat exchanger 30 are connected through the second cable 23, and the second cooling medium is passed through the second cable 23. The charging gun 21 generates a lot of heat during the charging process. After the second cooling medium absorbs the heat in the charging gun 21, it flows into the heat exchanger 30 driven by the second pump 22. In the heat exchanger 30 , the first cooling medium in the first circulation loop 10 absorbs the heat generated by the second cooling medium in the second circulation loop 20 , and the cooled second cooling medium continues to flow into the charging gun 21 along the second cable 23 to absorb the heat in the charging gun 21 again.

[0030] It can be understood that by setting the first circulation loop 10 and the second circulation loop 20, the first circulation loop 10 and the second circulation loop 20 share a heat exchanger 30, and the first circulation loop 10 is used in the heat exchanger 30 to cool the second circulation loop 20, so that the temperature of the second cooling medium flowing into the charging gun 21 in the second circulation loop 20 is always maintained within a reasonable range, thereby ensuring the cooling effect of the charging gun 21 and improving the charging efficiency and safety performance of the charging gun 21.

[0031] In one embodiment, the first cooling medium is water. It is understandable that by setting the first cooling medium to water, the second cooling medium in the second circulation loop 20 can be better cooled.

[0032] In one embodiment, the second cooling medium is cooling oil. It can be understood that the cooling oil can better absorb the heat in the charging gun 21 and better cool the charging gun 21.

[0033] It can be understood that water is used as the cooling medium in the first circulation loop 10, and oil is used as the cooling medium in the second circulation loop 20. Different circulation loops use different cooling media to give play to the characteristics of different cooling media and improve the performance of each circulation loop.

[0034] In one embodiment, in the first circulation loop 10, the compressor 11, the condenser 12, the first pump 13 and the heat exchanger 30 are connected in sequence.

[0035] It can be understood that by connecting the compressor 11, the condenser 12, the first pump 13 and the heat exchanger 30 in sequence, the first cooling medium can flow through the compressor 11, the condenser 12, the first pump 13, the heat exchanger 30 in sequence, and flow back into the compressor 11, thereby realizing the circulation of the first cooling medium in the first circulation loop 10 and improving the cooling efficiency of the second cooling medium in the second circulation loop 20.

[0036] In one embodiment, in the second circulation loop 20 , the charging gun 21 , the second pump 22 and the heat exchanger 30 are connected in sequence.

[0037] It can be understood that by connecting the charging gun 21, the second pump 22 and the heat exchanger 30 in sequence, the second cooling medium can flow through the charging gun 21, the second pump 22, the heat exchanger 30 in sequence and flow back into the charging gun 21, thereby cooling the charging gun 21.

[0038] In one embodiment, the first pump 13 drives the first cooling medium condensed by the condenser 12 into the heat exchanger 30. The first cooling medium absorbs heat in the heat exchanger 30 and flows into the compressor 11. After the compressor 11 compresses the first cooling medium, the first cooling medium re-enters the condenser 12 for condensation.

[0039] It can be understood that the first cooling medium condensed by the condenser 12 can be driven into the heat exchanger 30 by the first pump 13, so as to increase the flow rate of the first cooling medium.

[0040] In one embodiment, the second pump 22 drives the second cooling medium after absorbing the heat of the charging gun 21 into the heat exchanger 30. After the second cooling medium is cooled in the heat exchanger 30, it flows back into the charging gun 21 to cool the charging gun.

[0041] It can be understood that the second cooling medium flowing out of the charging gun 21 is driven into the heat exchanger 30 by the second pump 22, so as to increase the flow rate of the second cooling medium.

[0042] The utility model also proposes a charging pile, including the above-mentioned cooling system 100. The specific structure of the cooling system 100 of the present application refers to the above-mentioned embodiment. Since the cooling system 100 adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0043] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
