  • Heat exchanger device for a motor vehicle, method for operating a heat exchanger device and method for producing a heat exchanger device
    Patent number: 12679168
    Abstract: A heat exchanger device for a motor vehicle includes a main body, through which a temperature-control medium can flow, and a media-conveying device which passes through the main body and by which a medium to be temperature-controlled can be conveyed through the main body. As a result, the temperature of the medium to be temperature-controlled can be controlled by heat exchange with the temperature-control medium. The main body is produced in an integral injection molding process, as a result of which the main body is closed on the periphery and open-pored in the interior.
