Cooling device for a vehicle battery, vehicle battery and method for producing a cooling device

摘要

The device (10) has a cooling plate (12) formed by planar metal sheets (28) and a transformed metal sheet (30). The metal sheets are connected by joining surfaces (32). The transformer metal sheet comprises a hairpin-shaped recess (34) with respect to the joining surfaces. The recess with the planar metal sheets forms coolant lines (14). The metal sheet comprises recesses (27, 36) with respect to the joining surfaces. The recesses with the planar metal sheets form coolant-free cavities (20) for reinforcing the plate. An electrical insulating layer (26) is provided with ceramic additives. Independent claims are also included for the following: (1) a vehicle battery (2) a method for manufacturing a cooling device.
