[0003] For example, patent number CN210816779U is an ultra-high thermal conductivity aluminum profile extrusion die for a power battery cooling system, including a threaded aluminum extrusion module and a fixing nut. The threaded aluminum extrusion module includes an aluminum circular fixing module, an external thread connector and an extrusion die groove. The aluminum circular fixing module is provided with an external thread connector in the middle of the outer wall.
