Heat-exchange device, in particular for a car

摘要

The device (10) has a thermal unit (11) arranged in contact with a metal foam (1) so as to allow heat transfer between the thermal unit and the metal foam. The thermal unit is fixed with the metal foam by a connection obtained from formation of the metal foam and the thermal unit. The thermal unit carries a heat source or a light source i.e. LED (22). The metal foam and the thermal unit form a monolithic part. The thermal unit extends on a face (40) of the metal foam. An independent claim is also included for a method for forming a thermal unit with a metal foam.
