1. A battery housing assembly which is temperature-controlled by a fluid, the battery housing assembly comprising:
a battery housing which encloses an interior for receiving a plurality of battery cells; and
a heat transfer device which has an inlet, an outlet, and at least one fluid channel arranged fluidically therebetween, wherein the fluid flows through the heat transfer device from the inlet to the outlet via the at least one fluid channel,
wherein:
the at least one fluid channel is arranged in the interior and a contact side of the at least one fluid channel is pressable against at least one contact element to the plurality of battery cells in order to transfer heat, and
a plurality of expansion elements are arranged on a bracing side of the at least one fluid channel that is opposite the contact side, whereby, as a result of the fluid in the heat transfer device being pressurized, the plurality of expansion elements expand in order to press the at least one fluid channel against the at least one contact element by bracing against a bracing surface.
