    摘要: A battery housing assembly includes a battery housing which encloses an interior for receiving a plurality of battery cells. A heat transfer device which has an inlet, an outlet, and at least one fluid channel arranged fluidically therebetween. The fluid flows through the heat transfer device from the inlet to the outlet via the at least one fluid channel that is arranged in the interior. A contact side of the channel is pressed against at least one contact element to the battery cells in order to transfer heat. At least one expansion element, as a result of the fluid in the heat transfer device being pressurized, expands in order to press the at least one fluid channel against the at least one contact element by bracing against a bracing surface.
