Abstract: A heat siphon (3) that serves as a contact pressure unit has a peripheral wall (30) which is designed for areal contact with the surface to be cooled (12). The contact pressure unit mechanically prestresses the contact wall in order to produce an areal contact pressure of the contact face against the surface to be cooled when the cooling device is fastened to the electrical operating unit. An independent claim is also included for a producing method for a cooling device.

Abstract: The present invention provides a fluid-to-fluid through-the-wall heat exchanger for condensation of a vapour in a primary fluid stream, characterised in that the flow path (5) of the primary fluid stream is defined by an inner cylinder (1), an outer cylinder (2) arranged concentrically to and surrounding the inner cylinder, and a helical space holder (3) arranged between the inner and the outer cylinder. This condenser is easily coated such that all wetted materials are corrosion resistant. Compared to other condensers with identical ratings, this heat exchanger shows a smaller flow resistance, resulting in a smaller power demand of the blower or pumps. It is therefore particularly suitable for fuel cell systems where the condensed water has to be recirculated in the system and where purity demands are high and parasitic blower power should be minimal. The manufacturing of such a double envelope cylindrical heat exchanger is particularly simple and cost effective.

Abstract: A vacuum switch chamber has first and second contact pieces (11;12) for switching an electric current flowing through the vacuum chamber. To remove heat arising from the electric current in the vacuum chamber, at least one heat tube (1) is provided.
