The number of liquid cooling plates 130 in each row is less than the number of rows of liquid cooling plates 130. A connection method of more parallel and less series is used as much as possible, so that the temperature of each row of liquid cooling plates 130 is as consistent as possible, ensuring that the temperature control of each row of batteries 120 is consistent, and ensuring the stable performance of the batteries 120.

[0059] In the present application examples, see Figure 2 , the liquid inlet main pipe 340 and the liquid outlet main pipe 350 each include a plurality of pipe sections, and the adjacent pipe sections are sealed and connected by flanges. The number of pipe sections can be adjusted according to the actual required length to facilitate the assembly of the liquid inlet main pipe 340 and the liquid outlet main pipe 350. In addition, a pipe bracket 360 is provided, and a plurality of pipe brackets 360 are arranged at intervals along the length direction of the liquid inlet main pipe 340 and the liquid outlet main pipe 350.

[0064] In some embodiments, see Figure 6 , further comprising a control module 400, the battery assembly 120 further comprising a temperature detection device 140, the temperature detection device 140 being configured to detect the temperature inside the battery 120, the temperature detection device 140 and the temperature adjustment device 200 being respectively connected to the control module 400, the control module 400 being configured to: receive the temperature information of the battery 120 detected by the temperature detection device 140; and control the temperature adjustment device 200 to cool or heat the liquid cooling plate 130 according to the temperature information. The control module 400 may have a single chip microcomputer, the temperature detection device 140 is a temperature sensor, and the temperature sensor is disposed inside the battery 120.

[0065] Exemplarily, the control module 400 is provided with a first temperature threshold and a third temperature threshold, wherein the first temperature threshold is greater than the third temperature threshold. When the temperature value detected by the temperature detection device 140 is greater than the first temperature threshold, the control module 400 controls the temperature adjustment device 200 to cool the liquid cooling plate 130, and the liquid cooling plate 130 cools the battery 120; when the temperature value detected by the temperature detection device 140 is less than the third temperature threshold, the control module 400 controls the temperature adjustment device 200 to heat the liquid cooling plate 130, and the liquid cooling plate 130 heats the battery 120.

[0066] In the embodiment of the present application, the control module 400 automatically controls the temperature adjustment device 200 to cool or heat according to the temperature, and the temperature adjustment has a high degree of automation and good sensitivity.

When the temperature detection device 140 detects that the temperature of the battery 120 is higher than the first temperature threshold, the control module 400 controls the cooling module 210 to turn on the heating module 220 and turns off the heating module 220 to cool the liquid cold plate 130. When the temperature detection device 140 detects that the temperature of the battery 120 is lower than the third temperature threshold, the control module 400 controls the cooling module 210 to turn off the heating module 220 and turns on the heating module 220 to heat the liquid cold plate 130.

The control module 400 is configured to receive the first temperature information detected by the first temperature sensor 2161, and the control module 400 controls the compressor 215 to work according to the first temperature information. For example, a second temperature threshold is set in the control module 400. When the first temperature information is greater than the first temperature threshold, the control module 400 controls the compressor 215 to increase the cooling capacity; otherwise, the control module 400 controls the compressor 215 to reduce the cooling capacity.

[0071] In some embodiments, see Figure 3, the first monitoring device 216 includes a first pressure sensor 2162.

The control module 400 is configured to receive the first pressure information detected by the first pressure sensor 2162, and the control module 400 controls the high-pressure switch 217 to work according to the first pressure information. For example, a first pressure threshold is set in the control module 400. When the first pressure information is greater than the first pressure threshold, the control module 400 controls the high-pressure switch 217 to open and issue an alarm message; otherwise, the control module 400 controls the high-pressure switch 217 to close.

[0073] In the embodiment of the present application, the cooling module 210 and the heating module 220 of the temperature adjustment device 200 are connected to the liquid cooling plate 130 through the circulation pipeline 230. The pipeline design is simple, easy to assemble, and reduces the volume of the temperature adjustment device 200.

[0074] In some embodiments, see Figure 3 and Figure 4 , the circulation pipeline 230 includes a first liquid inlet end 231, a first liquid outlet end 232, a second liquid inlet end 233 and a second liquid outlet end 234. The first liquid inlet end 231 and the first liquid outlet end 232 are respectively connected to the refrigeration module 210. For example, the first liquid inlet end 231 and the first liquid outlet end 232 are connected to the plate evaporator 214. The second liquid inlet end 233 is connected to the liquid outlet end of the liquid cooling plate 130. For example, the second liquid inlet end 233 is connected to the liquid outlet main pipe 350 through a pipe joint. The second liquid outlet end 234 is connected to the liquid inlet end of the liquid cooling plate 130. For example, the second liquid outlet end 234 is connected to a section of the liquid inlet main pipe 340 through a pipe joint. The heating module 220 is arranged between the first liquid inlet end 231 and the second liquid inlet end 233. The heating module 220 is a heater, and the heater is arranged between the first liquid inlet end 231 and the second liquid inlet end 233.

When the liquid cooling plate 130 is heated, the heating module 220 is turned on and the cooling module 210 is turned off. When the liquid cooling plate 130 is cooled, the heating module 220 is turned off and the cooling module 210 is turned on. The same set of circulation pipelines can realize cooling and heating respectively, and the pipeline structure is simple.

[0075] In some embodiments, see Figure 3 and Figure 4 The temperature adjustment device 200 further includes a second monitoring device 240, which is installed on the circulation pipeline 230 and is configured to monitor information on the circulation pipeline 230.

The second temperature sensor and the second pressure sensor are installed on the pipeline close to the second liquid outlet 234, and the third temperature sensor and the third pressure sensor are installed on the pipeline close to the second liquid inlet 233.

[0077] Exemplarily, the control module 400 is provided with a fourth temperature threshold, a fifth temperature threshold, a fourth pressure threshold and a fifth pressure threshold. In the cooling mode, when the second temperature information is greater than the fourth temperature threshold, the control module 400 controls the cooling module 210 to increase the cooling effect. In the cooling mode, when the third temperature information is greater than the fifth temperature threshold, the control module 400 controls the cooling module 210 to increase the cooling effect.

In the heating mode, when the third temperature information is less than the fifth temperature threshold, the control module 400 controls the heating module 220 to increase the heating effect. It can be understood that the specific values ​​of the fourth temperature threshold and the fifth temperature threshold in the heating mode and the cooling mode may be different.

The pressure differential switch 270 is configured to monitor the pressure difference across the second filter 260, and the pressure differential switch 270 is connected to the control module 400. The control module 400 is configured to receive the pressure difference and prompt the fault information of the second filter 260 according to the pressure difference.

[0082] For example, a pressure difference threshold is set in the control module 400. When the pressure difference is greater than the pressure difference threshold, it indicates that the second filter 260 is clogged. At this time, the control module 400 prompts that the second filter 260 is faulty, and the second filter 260 is replaced in time to reduce the probability of damage to other equipment in the circulation pipeline 230 due to the failure of the second filter 260.

[0083] In some embodiments, see Figure 3 and Figure 4 A fluid replenishing device 280 is provided on the circulation pipeline 230 , and the fluid replenishing device 280 is connected to the circulation pipeline 230 . The fluid replenishing device 280 is configured to replenish the circulation pipeline 230 with a medium.

[0084] The liquid replenishing device 280 is connected to the control module 400, and includes a liquid level meter and a liquid replenishing pump. The liquid level meter is used to monitor the liquid level in the circulation pipeline 230. When the liquid level is lower than the set liquid level threshold, the control module 400 controls the liquid replenishing pump to replenish the medium fluid to the circulation pipeline 230 to ensure the cooling or heating effect of the liquid cold plate 130.

[0085] In some embodiments, see Figure 3 and Figure 4, the circulation pipeline 230 is also provided with an exhaust valve 235 and / or a drain valve 236. The exhaust valve 235 and / or the drain valve 236 are arranged on the pipeline between the first liquid outlet 232 and the second liquid outlet 234. The drain valve 236 can be used to empty the medium fluid in the circulation pipeline 230, and the temperature regulating device 200 can be repaired and other operations. The exhaust valve 235 can discharge the gas in the circulation pipeline 230, reducing the probability of the risk of the circulation pipeline 230 bursting due to the high internal air pressure.

[0086] In some embodiments, see Figure 3 and Figure 4 The circulation pipeline 230 is also provided with a flow switch 290, which is configured to adjust the liquid inlet flow of the liquid cooling plate 130. The flow switch 290 is arranged on the pipeline between the first liquid outlet 232 and the second liquid outlet 234 to adjust the liquid outlet pressure of the second liquid outlet 234.

[0087] In some embodiments, see Figure 3 and Figure 4 The circulation pipeline 230 includes a liquid inlet pipeline 237, a liquid outlet pipeline 238 and a maintenance pipeline 239. A ball valve is provided on the maintenance pipeline 239. The liquid inlet pipeline 237 is arranged between the first liquid inlet end 231 and the second liquid inlet end 233. The liquid outlet pipeline 238 is arranged between the first liquid outlet end 232 and the second liquid outlet end 234. The maintenance pipeline 239 is arranged between the liquid inlet pipeline 237 and the liquid outlet pipeline 238. The maintenance pipeline 239 connects the liquid inlet pipeline 237 and the liquid outlet pipeline 238. In the maintenance mode, the ball valve is opened, and the liquid inlet pipeline 237, the liquid outlet pipeline 238 and the maintenance pipeline 239 are connected. In the cooling mode or the heating mode, the ball valve is closed, and the liquid inlet pipeline 237 and the liquid outlet pipeline 238 are connected.
