Description

Technical Field

[0001] This utility model relates to the field of energy storage temperature control technology, specifically to an energy storage temperature control unit. Background Technology

[0002] The energy storage temperature control unit is the core temperature control equipment of the electrochemical energy storage system. It maintains the battery pack's operating temperature within the range of 15℃ to 35℃, controls the temperature difference between individual cells to ≤5℃ (the liquid cooling solution can reach ±0.5℃), prevents thermal runaway and extends battery life, and maintains a relative humidity of 5% to 95% without condensation to avoid electrolyte failure or short circuit. It ensures the safe and efficient operation of the battery pack by actively regulating the temperature.

[0003] The current mainstream temperature control components use cold plate liquid cooling. Liquid cooling components need to be cleaned regularly, otherwise metal shavings, oil and other impurities deposited in the pipes will block the flow channels, resulting in poor coolant flow, reduced heat exchange efficiency, and the temperature difference on the battery surface may exceed the safety threshold of 5°C. However, the current methods of cleaning the pipes are extremely troublesome and inconvenient to use. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] Please see Figures 1-5 This utility model provides a technical solution: An energy storage temperature control unit includes a body 1. The body 1 has an internal self-cleaning mechanism, comprising a drive box 6 located at the top of the body 1 and a liquid-cooled unit 4 located above the drive box 6. A water pump 14 and a vacuum pump 15 are fixedly installed inside the drive box 6. The output ends of the water pump 14 and the vacuum pump 15 are fixedly connected to the same liquid-cooled pipe 16. The liquid-cooled pipe 16 is installed at the bottom of the liquid-cooled unit 4 through the drive box 6. The water pump 14 in the self-cleaning mechanism drives the cleaning fluid to circulate within the pipe, utilizing the kinetic energy and chemical action of the cleaning fluid to flush the inner wall of the pipe, efficiently cleaning metal debris, oil stains, and other impurities, preventing flow channel blockage, and ensuring heat exchange efficiency. Simultaneously, the vacuum pump 15 creates a negative pressure environment to quickly and thoroughly extract residual cleaning fluid from the pipe. Thus, the self-cleaning mechanism makes cleaning and maintenance of the liquid-cooled system more convenient.

[0022] The body 1 has multiple battery packs 7 inside, and each battery pack 7 has a coil 9 at the bottom. The multiple battery packs 7 are connected by a connecting pipe 8. When the coolant flows in the coil 9, it can absorb the heat generated by the battery pack 7 during operation. The design of the coil 9 can increase the contact area with the battery pack 7, thereby improving the heat exchange efficiency and quickly regulating the temperature of the battery pack 7.

[0023] A switching mechanism is provided at the top of the battery pack 7 located at the top of the body 1. The switching mechanism includes a telescopic tube 10 fixedly installed at the top of the battery pack 7. The telescopic tube 10 is telescopic, which is convenient for connecting to the interface 13 of different heights, thus improving the convenience and reliability of switching.

[0024] The top end of the telescopic tube 10 is fixedly installed with a connector 11, and a tightening ring 12 is rotatably installed on one side of the connector 11. The tightening ring 12 and the interface 13 are engaged by threads. After tightening and fixing, the connection can be sealed to prevent fluid leakage.

[0025] Both the liquid cooling unit 4 and the drive box 6 have an interface 13 on one side. The tightening ring 12 in the switching mechanism can cooperate with the interface 13 on the side of the liquid cooling unit 4 and the drive box 6. The interface 13 is used to connect with the connector 11. One interface is provided on both the liquid cooling unit 4 and the drive box 6, so that the unit can switch between temperature control mode and cleaning mode. This ensures the operation of the battery pack 7 and also allows for cleaning and maintenance of the liquid cooling system, making it extremely convenient to use.

[0026] The liquid cooling pipe 16 in the self-cleaning mechanism is connected to the connecting pipe 8, coil 9, and telescopic pipe 10 in the switching mechanism. The connection pipe 8, coil 9, telescopic pipe 10, and liquid cooling pipe 16 are connected, which can ensure that the coolant can be circulated and used under normal temperature control conditions, saving resources, and can also make the cleaning fluid circulate in cleaning mode to ensure that the pipeline can be thoroughly cleaned.

[0027] When in use, when the energy storage temperature control unit is working normally, the tightening ring 12 of the switching mechanism is connected to the interface 13 on the liquid cooling unit 4. The liquid cooling unit 4 forms an interconnected pipeline circuit through the liquid cooling pipe 16, connecting pipe 8, coil 9 and telescopic pipe 10 to perform liquid cooling temperature control on multiple battery packs 7. The heat dissipation holes 3 on the door 2 will dissipate heat through its internal fan to maintain the working temperature of the battery pack 7 within a suitable range, thereby ensuring the normal operation of the battery pack 7. At the same time, the high-voltage box 5 provides high-voltage power support for the entire unit, ensuring the stable operation of each component. When the liquid cooling system needs to be cleaned and maintained, the switching mechanism can be used to engage the tightening ring 12 with the interface 13 of the drive box 6. At this time, the water pump 14 of the drive box 6 will draw the external cleaning fluid and push the cleaning fluid to circulate in the loop formed by the liquid cooling pipe 16, the connecting pipe 8, the coil 9 and the telescopic pipe 10. The cleaning fluid is cleaned by using its kinetic energy and chemical properties. After cleaning, the vacuum pump 15 will use its own characteristics to create a negative pressure environment in the pipe to draw out the residual cleaning fluid in the pipe, thus completing the cleaning and maintenance of the liquid cooling system. Finally, reconnect the tightening ring 12 to the liquid cooling unit 4 and continue normal temperature control operation.

[0028] Example 2

[0029] Please see Figures 1-5 This utility model provides a technical solution: A door 2 is rotatably installed on one side of the body 1. A heat dissipation hole 3 is provided inside the top of the door 2. The heat dissipation hole 3 is aligned with the liquid cooling unit 4 on the body 1. A fan is installed inside the heat dissipation hole 3 to dissipate the heat absorbed by the liquid cooling unit 4 from the battery pack 7, ensuring the heat dissipation of the liquid cooling unit 4 and improving the stability and service life of the liquid cooling unit 4 during operation.

[0030] The high-pressure box 5 is installed inside the body 1. The high-pressure box 5 is at the same level as the drive box 6 and is located below the liquid-cooled unit 4 together with the drive box 6. The high-pressure box 5 is the core control unit of the high-pressure power circuit of the energy storage system.

[0031] Unlike Embodiment 1, the liquid cooling unit 4 can be cooled through the heat dissipation holes 3 on the door 2, which improves the stability and service life of the liquid cooling unit 4 during operation.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
