Description

Technical Field

[0001] This utility model relates to the field of energy storage system technology, and in particular to a single-cooling liquid-cooled temperature control device for mobile charging power supplies. Background Technology

[0002] With the continuous development of the new energy industry, the energy storage industry has also been continuously promoted. For example, products such as home energy storage, commercial and industrial outdoor energy storage cabinets, containerized industrial energy storage systems, and new energy vehicles are widely used. In particular, people like fast charging for energy storage products because of their high charging power and short charging time. However, batteries generate a lot of heat, and temperature directly affects the battery's lifespan. This requires heat dissipation of the battery module, and the best module at present is the liquid cooling module.

[0003] For example, Chinese patent CN219913686U discloses a liquid-cooled temperature control unit, which includes a shell, partition, refrigerant heat exchanger, compressor, fan, plate heat exchanger, water pump, and water supply pipe. It mainly achieves this by rearranging the liquid-cooled temperature control unit, placing the refrigerant system and liquid cooling system on the upper and lower sides of the unit respectively, and connecting them through the evaporation and condensation pipes of the refrigerant system.

[0004] The liquid-cooled temperature control unit mentioned above places the fan in the first space inside the casing, and the number of fans is more than one set, which results in the fans occupying a large space, thus making the final equipment larger in size and area, and also making it difficult to install and transport.

[0022] To more clearly illustrate this utility model, the following description, in conjunction with preferred embodiments, further clarifies the invention. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figures 1 to 3 As shown in the figure. This utility model embodiment proposes a single-cooling liquid-cooled temperature control device for mobile charging power supply, including a chassis 10. The chassis is generally rectangular in shape and hollow inside. A condenser assembly 1 and a fan 2 are respectively arranged inside and outside one side of the chassis 10. The condenser assembly 1 is arranged along the height of the chassis 10.

[0025] Inside the chassis 10 are fixed the following: a control unit 3 (ECU), a compressor 4 and an evaporator 5 located on the same side; an electric water pump 6 and an expansion tank 7 located on the other side; the electric water pump 6 is connected to a first inlet pipe 61 and a first outlet pipe 62; the expansion tank 7 has an inlet pipe and an outlet pipe 71; the compressor 4 has an inlet and an outlet; the evaporator 5 is connected to a second inlet pipe 51, a second outlet pipe 52, a throttling pipe 53, a steam pipe 54, and a high-pressure refrigerant injection pipe 55; the throttling pipe 53, the steam pipe 54, and the high-pressure refrigerant injection pipe 55 are connected by an electronic three-way valve; and the condenser assembly 1 has a third inlet pipe 11 and a third outlet pipe 12.

[0026] The compressor 4 outlet is connected to the third liquid inlet pipe 11 of the condenser assembly 1 via a first pipeline, and the compressor 4 inlet is connected to the steam pipe 54 of the evaporator 5. The first liquid inlet pipe 61 of the electronic water pump 6 and the water inlet pipe of the expansion tank 7 are connected to a main liquid inlet pipe 8 via an electronic three-way valve. The first liquid outlet pipe 62 of the electronic water pump 6 is connected to the second liquid inlet pipe 51 of the evaporator 5 via a solenoid valve. The throttling pipe 53 of the evaporator 5 is connected to the third liquid outlet pipe 12 of the condenser assembly 1, and a low-pressure refrigerant injection pipe 56 branches outward from the throttling pipe 53 of the evaporator 5. The second liquid outlet pipe 52 of the evaporator 5 is connected to the exhaust pipe of the expansion tank 7, and the second liquid outlet pipe 52 of the evaporator 5 is also connected outward to a main water outlet pipe 9.

[0027] The ends of the main liquid inlet pipe 8, the main water outlet pipe 9, the high-pressure refrigerant injection pipe 55, and the low-pressure refrigerant injection pipe 56 all extend outward from the casing 10.

[0028] This embodiment utilizes a compressor-condenser-evaporator-compressor configuration to construct a complete refrigeration system, with intelligent control of each component achieved by the control unit 3. The compressor 4 extracts gaseous refrigerant from the evaporator 5 and pressurizes it into the condenser assembly 1. The high-pressure gaseous refrigerant liquefies upon passing through the condenser assembly 1, thereby achieving heat exchange, and the released heat is carried away by the air outside the casing. The high-pressure liquid refrigerant enters the throttling pipe 53 through the high-pressure refrigerant injection pipe 55 to reduce its pressure. Then, the low-pressure liquid refrigerant vaporizes in the evaporator 5 to perform heat exchange and absorb heat. The cooled air near the condenser assembly 1 is blown into the casing 10 by the fan 2, and the gaseous refrigerant is again drawn away by the compressor 4 and pumped into the condenser assembly 1, thus continuously cycling and exchanging heat.

[0029] When the compressor 4 is not working, low-temperature liquid is introduced through the main liquid inlet pipe 8. The low-temperature liquid is pumped into the evaporator 5 by the electric water pump 6, and then flows out through the main water outlet pipe 9. This can cool down the hot object. The expansion tank 7 can compensate for the expansion and contraction of the coolant when passing through the evaporator 5, thus protecting the system and preventing damage due to excessive system pressure.

[0030] In this embodiment, the chassis 10 includes an L-shaped main body plate 110, two chassis side panels 120, a chassis top panel 140, and a chassis interface side panel 130. The main body plate 110, chassis side panels 120, chassis top panel 140, and chassis interface side panel 130 are assembled together to form a cuboid chassis 10. This modular design facilitates disassembly, assembly, and subsequent maintenance. During the design process, the two chassis side panels 120, chassis top panel 140, and chassis interface side panel 130 are all fastened to the main body plate 110 by screws. The chassis top panel 140 is positioned vertically opposite a part of the main body plate 110. The condenser assembly 1 and fan 2 are respectively located on the inner and outer sides of the other part of the main body plate 110. The control unit 3, compressor 4, evaporator 5, electric water pump 6, and expansion tank 7 are all installed and fixed in their respective positions within the chassis 10 using corresponding brackets.

[0031] The main body plate 110, the two chassis side panels 120, and the chassis interface side panel 130 are all provided with a number of heat dissipation holes (not marked in the attached figure) to improve the ventilation and heat dissipation performance of the chassis. The chassis interface side panel is also provided with a power interface for connecting the control unit to an external power source.

[0032] The lower outer wall of the chassis interface side panel 130 and the lower outer wall of the chassis side cover 120 corresponding to the chassis interface side panel 130 are respectively provided with two outwardly protruding rubber shock-absorbing mounting blocks 101 through fixed brackets. The four rubber shock-absorbing mounting blocks are used to improve the stability of the chassis after fixed installation and reduce noise during operation.

[0033] Lifting hooks 102 are provided on one top corner of the outer wall of the chassis interface side panel 130, one top corner of the outer wall of the chassis side cover 120 corresponding to the chassis interface side panel 130, and two top corners of the outer wall of the part of the main body plate 110 where the fan 2 is installed. The four lifting hooks are on the same horizontal plane. The overall weight of the chassis in this embodiment is approximately 38kg, which is not light. The four lifting hooks improve the installation efficiency, allowing the chassis to be quickly and accurately lifted and fixed, reducing operation time and improving installation efficiency.

[0034] In this embodiment, a shroud 103 surrounding the fan 2 is also provided outside the chassis 10. The front end of the shroud is open, and the overall length of the shroud is greater than the overall length of the fan. The shroud is used to guide the airflow at the fan position and optimize high-speed stability.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
