HEAT TRANSFER DEVICE FOR TEMPERING BATTERIES AND COMPONENTS OF THE POWER ELECTRONICS

A device for the transfer of heat to control the temperature of batteries and components of the power electronics, particularly for an electric vehicle or a hybrid vehicle, includes an inlet for a fluid and an outlet for the fluid as well as at least two fluid-conducting plate-shaped heat exchanger elements, of which a first plate-shaped heat exchanger element and a second plate-shaped heat exchanger element have planar contact with one another for the transfer of heat. In doing so, the second plate-shaped heat exchanger element is formed for planar contact with a heat transfer surface of a battery and/or a component of power electronics. At least one fluid connection is formed between the first plate-shaped heat exchanger element and the second plate-shaped heat exchanger element such that fluid escaping from the first plate-shaped heat exchanger element can flow through the second plate-shaped heat exchanger element.
