4680 Big Size Lithium Ion Cylindrical Batteries Aluminum Extruded Micro Channel Cooling Tubes for BEV Battery Pack

Thermal management of cylindrical lithium-ion battery based on a liquid cooling method , which is widely used for Tesla. Along the development of the electric vehicles, Tesla is always to attempt to use different types of the cylindrical cells such as 18650 cells, 21700 cells and the latest 4680cells. Each changes Of cells will request to design new liquid cooling ribbons to match the cells. To meet the market demands, Trumony as the heat exchanger manufacturer, we are always to develop the cooling tubes for our clients. Currently , we have different cooling solution for battery management system. And we also can provide liquid cooling plate or aluminum cooling pipes samples for testing.
