specific Embodiment approach

[0032] Furthermore, please also refer to Figure 1 to Figure 2 , as a specific implementation of the power battery cooling system provided by the present invention, the power battery cooling system further includes a cooling unit 50 disposed between the multiple sub-cavities h and communicated with the air inlet 11 and the air outlet 12 respectively. Specifically, in this embodiment, the air inlet and outlet ends of the cooling unit 50 are sealed and connected to the air inlet 11 and the air outlet 12 respectively. The cooling unit 50 cools down, and the cooled cooling unit 50 exchanges heat with the gas in the accommodating cavity H, thereby lowering the temperature in the accommodating cavity H, and then the gas in the cooling unit 50 is discharged into the air through the gas outlet 12 In the atmosphere, the cold air unit 50 is mainly used to speed up the cooling speed and reduce energy loss.

Abstract

The invention provides a cooling system of a power battery. The cooling system comprises a battery box, a battery body, and a temperature regulating device, and further comprises a temperature detection device and a controller, wherein the battery box has an airtight accommodation cavity, the battery body is arranged in the accommodation cavity, the temperature regulating device is arranged at oneside of the battery box and can regulate temperature in the accommodation cavity in an air cooling manner, the temperature detection device is used for detecting temperature in the accommodation cavity, and the controller is electrically connected with the temperature regulating device and the temperature detection device separately. According to the cooling system, the battery body is arranged in the battery box with the airtight accommodation cavity, and the temperature regulating device regulates temperature in the accommodation cavity in the air cooling manner, so that potential risks ofa liquid cooling technique are prevented, and technical problems of high cost and complex structure are solved; the temperature detection device and the controller electrically connected with the temperature detection device and the temperature regulating device separately are arranged so as to form a closed temperature regulating loop, therefore, temperature of the battery body is controllable, and the whole system has a simple structure and is low-cost.

Description

technical field [0001] The invention belongs to the technical field of batteries, and more specifically relates to a power battery cooling system. Background technique [0002] In the actual use of power battery packs, power batteries are highly densely arranged. If there is no cooling system, heat will inevitably accumulate inside the battery pack, and thermal runaway is very likely to occur, resulting in irreparable property losses. Even if there is no thermal runaway phenomenon, it will inevitably cause a large temperature difference between the battery packs, thereby affecting the temperature consistency, reducing the service life of the battery pack, increasing the replacement frequency of the battery pack, and increasing the use cost of the electric vehicle. Therefore, the cooling system is not only a means to ensure the safety of the battery, but also can increase the service life of the power battery and improve the performance of the vehicle. [0003] As far as the...
