New Energy water cold plate is a device used for battery thermal management, which mainly takes away the heat generated during the operation of the battery by liquid cooling, keeping the battery within the appropriate temperature range. It works by forming flow channels inside the sheet metal, through which coolant flows to absorb and carry away the heat generated by the battery.
Structure and materials
The new energy water cold plate is usually composed of multi-layer materials, including cooling channels, heat sinks and connection interfaces. In order to ensure good thermal conductivity, most of the water cold plates are made of aluminum alloy material, because aluminum alloy has high thermal conductivity and light weight, which helps to reduce the overall weight of new energy vehicles.
Process of production
There are many kinds of flow channel forming processes of water cold plate, including friction welding, vacuum brazing, buried copper pipe and deep hole drilling. Each of these processes has its own characteristics, and choosing the right process can ensure the performance and reliability of the water cooling plate . For example, vacuum brazing is performed in a vacuum environment to obtain a tighter welding effect; The deep hole drilling process works by machining a flow path on a sheet metal.
Application scenarios
New energy water cooling plate is widely used in battery cooling management system of new energy vehicles, especially in pure electric vehicles and hybrid electric vehicles. Liquid cooling mode takes heat away from the battery by the refrigerant, keeping the battery within the optimal operating temperature range, thus extending battery life and improving vehicle performance . Catl's Kirin battery, for example, places a water cooling plate in the middle of the battery pack, optimizing space utilization and increasing battery capacity.
