Cold Water Plate For New Energy Vehicles

Cold Water Plate For New Energy Vehicles is the core component of the battery cooling system for new energy vehicles. Its main function is to effectively absorb and transfer the heat generated by the battery in the working process through the liquid cooling medium, in order to maintain the working temperature of the battery in the optimal range, so as to safeguard the performance of the battery and extend its service life.

Cold water plates are usually made of high thermal conductivity materials, such as aluminum or aluminum alloy, which not only have good thermal conductivity, but also are lightweight, which is conducive to reducing the quality of the whole vehicle. Its internal structure has a complex design and usually contains multiple runners and cooling fins, which help increase the contact area between the fluid and the plate surface and improve cooling efficiency. The layout and dimensions of the runners are optimized and designed according to the size and shape of the battery as well as the cooling requirements.

During the manufacturing process, the chilled water plate may undergo precision machining, such as CNC machining, stamping, or micro channel manufacturing techniques, to ensure its dimensional accuracy and surface finish. In addition, a thermally conductive coating may be applied to the contact surface in order to improve the efficiency of heat transfer between the coolant and the chilled water plate.

The design of the cold water plate also needs to take into account compatibility with the battery module, including size matching, mounting method, and possible thermal stress distribution. In practice, the cold water plate needs to work closely with the battery management system to achieve precise control of the battery temperature by accurately controlling the flow and temperature of the coolant.

With the development of new energy vehicle technology, the requirements for cooling systems are becoming more and more demanding, and the design of cold water panels is constantly being innovated, such as the development of new materials with higher thermal conductivity, the optimization of flow channel design to improve cooling efficiency, and the integration of sensors and control units to achieve intelligent cooling management.
