Problems solved by technology

[0002] The battery pack generally includes a number of single cells arranged in the casing. When the number of single cells in the battery pack is large, the heat dissipation of the battery pack during charging and use becomes a problem that needs to be paid attention to, otherwise the battery will heat up. The accumulation of heat will affect the use of the battery pack, which may cause instability of the battery pack and shorten the life of the battery pack
Although devices to speed up heat dissipation can be installed on the battery pack case, such as liquid cooling and air cooling, the heat accumulated between the single cells is difficult to dissipate

Embodiment

[0018] Example: such as figure 1 As shown, a battery pack cooling device includes a battery pack 1 and a heat exchange pipe 2 of the battery pack 1. The battery pack cooling device also includes a high-pressure gas source 3 and a vortex tube 4. The vortex tube 4 has a The outlet port of the source 3 communicates with the high-pressure gas inlet port 41 , the cold gas output port 42 and the hot gas output port 43 , and the cold gas output port 42 of the vortex tube 4 communicates with the input port 21 of the heat exchange pipe 2 . In this embodiment, two vortex tubes 4 are connected to the outlet end of the high-pressure gas source 3 , and other suitable number of vortex tubes 4 can also be connected to it according to the needs of use.

[0019] The heat exchange pipeline 2 in the present embodiment is as figure 2 As shown, the heat exchange pipeline 2 includes an input confluence main pipe 23 and an output confluence main pipe 24 communicated with the input end 21 and the o...

Abstract

The invention discloses a temperature regulation device for a battery pack. The device comprises the battery pack, a heat exchange pipeline of the battery pack, a high pressure air source and a vortex tube, wherein the vortex tube is provided with a high pressure air inlet end, a cold air output end and a hot air output end; the high pressure air inlet end is communicated with an outlet end of the high pressure air source; and the cold air output end or the hot air output end of the vortex tube is communicated with the input end of the heat exchange pipeline. The cooling or heating effect of the battery pack is greatly improved, the using cost of the temperature regulation device is low, and the device is convenient to maintain.

Description

technical field [0001] The invention relates to a battery pack temperature regulating device. Background technique [0002] The battery pack generally includes a number of single cells arranged in the casing. When the number of single cells in the battery pack is large, the heat dissipation of the battery pack during charging and use becomes a problem that needs to be paid attention to, otherwise the battery will heat up. The accumulation of heat will affect the use of the battery pack, which may cause instability of the battery pack and shorten the life of the battery pack. Although devices to accelerate heat dissipation, such as liquid cooling and air cooling, can be provided on the battery pack casing, it is difficult to dissipate the heat accumulated between the single cells. In order to solve the above problems, the inventor of the present application once proposed a Chinese patent application with publication number 101533934 and titled "Liquid Cooling Device for Batt...
