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.
Claims15
A heat exchanger device for use in a motor vehicle, comprising:
- a main body forming an integral structure, defining an interior volume configured to receive a fluid temperature control medium, the main body comprising:
- an inlet configured to convey a flow of the fluid temperature control medium into the interior volume,
- an outlet configured to convey the flow of the fluid temperature control medium out of the interior volume, and
- a plurality of air channels extending through the main body from air inlet openings formed on a first side of the main body to air outlet openings formed on a second side of the main body opposite the first side and facing the interior of the motor vehicle, wherein each air channel of the plurality of air channels is circumferentially enclosed along its length, and
- an air feed channel in fluid communication with each of the plurality of air channels, the air feed channel configured to convey a flow of air through the air feed channel and the plurality of air channels,
- wherein the flow of air through the plurality of air channels does not mix with any fluid temperature control medium within the interior volume of the main body by virtue of the circumferentially enclosed air channels, and
- wherein heat is exchanged between the flow of air through the plurality of air channels and the fluid temperature control medium within the interior volume of the main body.
