The battery thermal management unit in the current state in the industry has the following problems:
1. The condenser is arranged in parallel with the fan, and is limited by the fact that the distance between the condenser and the fan is too short, so that the wind speed of a cooling pipe of the condenser flowing through the fan cover surface and nearby is too high, the wind speed of the cooling pipe of the condenser far away from the fan cover surface is too low, the difference between the highest wind speed and the lowest wind speed of the condenser is large, and the cooling efficiency of the condenser is too low.
2. In the use process of the condenser, dust and impurities are attached to the surface of the condenser, and the performance of the radiator is affected after accumulation of the condenser, so that the condenser needs to be regularly maintained. The condenser in the present state is arranged inside the battery thermal management unit, and the cleaning can be performed only by disassembling the upper cover of the unit and disassembling the condenser later, so that the maintenance is time-consuming and labor-consuming.
3. The fan in the present state protrudes out of the machine set, and the fan blades are easy to accumulate dust to generate dynamic unbalance, so that the fan bearings are worn.
