Abstract
For a technical object whose temperature is to be controlled, in particular a battery for an electric vehicle drive, there is provided a heat exchanger arrangement, the heat exchanger of which is in the form of a heat-exchanging pouch which has an inflow and outflow duct and which is in heat-conducting contact with internal surfaces of the object whose temperature is to be controlled. The heat-exchanging pouch is produced in a simple manner by means of edge welding of two foil pieces arranged one above the other. The mounting of said heat-exchanging pouch in a narrow gap space of a heat exchanger arrangement, and good heat transfer to adjacent walls, are made possible by means of a pressure pouch which is likewise formed from a foil material and which is filled with a compressible medium.
