The battery is used as a core part of the electric automobile, and the performance and the service life of the battery directly determine the performance and the cost of the electric automobile.
The lithium ion power battery is a main power battery used for electric vehicles due to the advantages of long service life, low self-discharge rate, high specific power, high energy density, no pollution and the like. However, the lithium ion battery has an optimal temperature range problem during discharging, and when the temperature of the battery is too high or too low and exceeds the allowable working temperature range, the discharging capability is sharply reduced, and even the discharging is not allowed. In the actual charging and discharging process, the temperature of the battery is continuously increased due to heat accumulation, and auxiliary cooling measures are required to be taken in order to ensure the normal operation of the battery. In order to solve the above problems, a set of liquid cooling plates is usually disposed at the bottom of a module in a battery system, and the liquid cooling plates, a circulation pump, a pipeline, a heat exchanger of a lithium ion battery, and a liquid path heater form a set of circulation system. When the high-temperature battery needs to be cooled, the heat of the battery is brought into the heat exchanger by the circulating antifreeze, and the antifreeze is cooled in the heat exchanger by the refrigerant of the air conditioning system.
The water inlet structure of the conventional liquid cooling system usually adopts a structural mode of welding a water pipe and a water pipe fixing plate, and a certain number of through holes are arranged in the water pipe fixing plate for shunting. If welding fails, the risk of water entering the battery pack is easily caused, and the problem of uneven flow distribution is easily caused by shunting in the water pipe fixing plate.
