Problems solved by technology
At present, air-cooled and water-cooled heat dissipation methods are usually used for cooling new energy vehicle power batteries. Although the air-cooled heat dissipation method is low in cost, it is greatly affected by the ambient temperature, and the heat dissipation effect is not ideal under high temperature conditions. The traditional water-cooled heat dissipation method The way usually adopts the battery cooling plate
[0003] The study found that the calorific value of each part of the new energy vehicle battery pack is quite different, but the existing battery cooling plate cannot perform zoned cooling well, resulting in a better cooling effect on some areas of the battery pack, and poor cooling on some areas of the battery pack. The cooling effect is not good
[0004] Moreover, the existing internal waterway design of the battery cooling plate can only be analyzed by numerical simulation. Not only is the parameter setting complicated, but also the analysis speed is slow. Design progress is slow

The invention discloses a new energy vehicle battery cooling plate, which not only greatly improves the cooling effect on the new energy vehicle battery pack, ensures the efficient and safe operation of the new energy vehicle battery pack, but also can be matched more efficiently with a smaller total cooling liquid flow rate. The high-heat new energy vehicle battery pack can effectively reduce the manufacturing cost. The invention also discloses a waterway simulation analysis and demonstration device for the battery cooling plate, which can not only simulate the flow of cooling liquid very intuitively, but also replace the waterway numerical simulation analysis to a considerable extent, and has a simple structure, easy assembly, and low cost. It is easy to use, and the results are displayed quickly, which is suitable for more ordinary engineers.
Description
technical field [0001] The invention relates to the technical field of new energy vehicle battery cooling systems, in particular to a new energy vehicle battery cooling plate and a waterway simulation analysis and demonstration device thereof. Background technique [0002] The power of new energy vehicles is provided by the power battery storage on the vehicle, and the power battery requires stability, safety and reliability. Not only the heat released by the power battery during the energy conversion process will directly affect the stability of the battery, but also the low ambient temperature will also affect the power conversion of the battery, resulting in a low cruising range. Therefore, it is very important to control the temperature of the power battery. At present, air-cooled and water-cooled heat dissipation methods are usually used for cooling new energy vehicle power batteries. Although the air-cooled heat dissipation method is low in cost, it is greatly affecte...
