Problems solved by technology

The liquid cooling system of the power battery pack can effectively manage the temperature of the battery module so that it can work at the optimum temperature and maximize the performance of the battery. As a result, the entire liquid cooling system becomes complicated and fragile. The cold pipe is deformed when it is squeezed by external force, or the internal pressure increases due to impurities blocking the liquid cooling pipe. The excess pressure cannot be removed, which eventually causes the liquid cooling pipe to burst; or the liquid cooling pipe is caused by high frequency vibration. The system interface is loose and leaks, which reduces the insulation level of the outer box and causes electric shock hazards
[0005] In the patent No. CN201821202323.9, a power battery pack liquid cooling system with a high safety factor is provided. When the liquid cooling pipeline is blocked, causing the pressure in the pipeline to rise and destroying the liquid cooling circuit, the return valve can be used to The coolant that originally needs to enter the liquid cooling pipe in the battery box is drained back to the liquid cold box, avoiding the impact on the internal blocked pipeline, and at the same time, it can provide an alarm function when the coolant leaks, thereby improving the safety of the system; but not It can prevent the coolant in the battery pack from continuing to leak, and at the same time can only rely on external supplementary coolant, wasting coolant
