ABSTRACT:
A device for exchanging heat for motor vehicles, having at least one first component connected to an electrical power supply and whose temperature varies dependent on current flowing through the component, at least one second component including at least one first and at least one second part element each of which are at least indirectly conductively connected to the first component, wherein at least one part element includes a first connecting means and at least one electrical contact means which is at least indirectly conductively connected to at least one part element of at least one second component and serves to connect an electrical power supply wherein the contact means includes at least one second connecting means. Both of the connecting means include at least one flat portion and the first and the second connecting means interlock so as to result in a form-fitting connection between the first and the second connecting means and electrical contact is established at least between a primary surface of the flat portion of said first connecting means and a major face of the flat portion of said second connecting means.
