[0002] A battery pack is a combination of batteries. It can be a single battery or a series-parallel combination of batteries. If it is a battery connected in series or parallel, the model must be consistent. The battery pack can store and release electrical energy to continuously power the device. Heat exchange is the heat transfer process between two objects or parts of the same object caused by temperature difference. Heat exchange is generally completed through three methods: heat conduction, heat convection and heat radiation. Heat exchange can convert heat between objects, convert heat out when the temperature of the object is too high, and provide temperature for the object when the temperature is too low, so that the temperature of the object can be continuously maintained. Therefore, there is a special need for a battery pack thermal management device that can quickly perform heat exchange.

[0003] However, most of the existing battery pack thermal management devices that can quickly perform heat exchange do not have a heat exchange structure. The battery pack cannot maintain its temperature during operation, which will greatly affect the performance of the battery pack and also reduce the service life of the battery pack. Secondly, most battery packs are very troublesome to install. Utility Model Content

First, start the water pump 205, and the water pump 206 draws the water out of the water tank 204, and then discharges it into the water pipe 203 through the drain pipe 207. The water flows in the water pipe 203 and finally flows back to the water tank 204, thus completing the water circulation structure. When the heat in the battery pack 1 is too high, the water flowing in the water pipe 203 will first absorb the heat, and the temperature of the water will also increase. At this time, the heat pipe 20 8 will absorb the heat in the circulating water flow, the heat conducting plate 209 will absorb the heat in the heat conducting pipe 208, and the fan 210 will be started to blow the heat out. When the temperature in the battery pack 1 is too low, the heating pipe 211 will be energized for heating, and the heating pipe 211 will heat the water flow in the water tank 204. When the water flows in the water pipe 203, it can provide heat for the battery pack 1, thus completing the rapid heat exchange of the battery pack 1. Such a heat exchange structure is very convenient for cooling and heating, and has higher efficiency.

[0021] Furthermore, the water pumping pipe 206 forms a water pumping structure through the water pump 205 and the drain pipe 207, and the heat pipe 208 forms a heat dissipation structure through the heat conducting plate 209 and the fan 210. Through the setting of the water pump 205, the water pump 205 pumps the water in the water tank 204 through the water pumping pipe 206, and then transports the pumped water into the water pipe 203 through the drain pipe 207. Finally, the water flows back to the water tank 204 from the water pipe 203, thus completing a water circulation structure.

[0022] Furthermore, the mounting mechanism 3 includes a slider 301, a mounting block 302, a slide groove 303, a slot 304, a spring 305, a block 306, a mounting plate 307 and a bolt 308.

A spring 305 is provided inside the slot 304. One end of the spring 305 is fixedly connected to the block 306. The two side surfaces of the mounting block 302 are fixedly connected to the mounting plate 307. One end of the mounting plate 307 is provided with a bolt 308. When the battery pack 1 is in the position where it needs to be installed, the battery pack 1 is fixed to the position where it needs to be installed.

Through the setting of the slider 301 and the slide groove (303), the slider 301 slides inside the slide groove 303, driving the shell 201 to be installed on the mounting block 302, so that the battery pack 1 is fixedly installed on the mounting block 302.

[0024] Furthermore, the mounting block 302 forms a mounting structure through the mounting plate 307 and the bolt 308, and two groups of springs 305 are provided. Through the setting of the spring 305, the spring 305 will rebound when it is not under force, driving the clamping block 306 to return to its position, and the returned clamping block 306 fixes the slider in the mounting block 302.

[0025] Working principle: First start the water pump 205, the water pump 206 draws the water out of the water tank 204, and then discharges the water into the water pipe 203 through the drain pipe 207. The water circulates in the water pipe 203 and finally flows back to the water tank 204, thus completing the water circulation structure. When the heat in the battery pack 1 is too high, the water flowing in the water pipe 203 will first absorb the heat, and the temperature of the water will also increase. At this time, the heat pipe 208 will absorb the heat in the circulating water, and the heat conducting plate 209 will absorb the heat in the heat conducting pipe 208, start the fan 210, and the fan 210 will blow the heat out. When the temperature in the battery pack 1 is too low, the heating pipe 211 is energized for heating, and the heating pipe 211 will heat the water in the water tank 204. When the water flows in the water pipe 203, it can provide heat for the battery pack 1, thus completing the rapid heat exchange of the battery pack 1. When the heat exchange structure of the heat exchanger is cooled and heated, the heat exchange structure is very convenient for cooling and heating, and has higher efficiency. During installation, the mounting plate 307 is first fixed to the required installation location by bolts 308, and the mounting block 302 is also fixed to the required installation location together, and the slider 301 is pushed into the slide groove 303. The slider 301 entering the slide groove 303 will squeeze the block 306, and the block 306 squeezes the spring 305 into the slot 304. When the slider 301 completely enters the bottom of the mounting block 302, the slider 301 leaves the block 306, and the spring 305 will rebound without being subjected to force. The rebound of the spring 305 drives the block 306 to return to its original position, and the returned block 306 will fix the slider 301 in the mounting block 302, and the battery pack 1 is also fixed together in the required installation location. This installation method is faster and simpler, and the installation is more stable, thus completing a battery pack thermal management device that can quickly perform heat exchange.
