An apparatus for controlled heat transfer to and from a component

The invention concerns a coupling member for selective and controllable Warmubertragung from or on a component 3, which can be heated by an external and / or internal heating source, and which adjacent to a radiator 7 is arranged. The component coupling comprises a support plate 1, a first means for spacing 2a is arranged on at least that arranged on the means for spacing member 3 and the support plate 1 are capable of forming a first cavity defined 4a together with the means for spacing 2a. This cavity can be evacuated, if necessary, filled with a fluid medium or by flowing, whereby the heat transfer or heat dissipation can be controlled by the component in a simple manner.
