Abstract
In this method, a refrigerant () is compressed () in a refrigerating circuit, then condensed by cooling in a condenser (), then expanded in a throttle valve () and delivered in the expanded state, in the form of wet vapor (), to an evaporator () that is in thermally conductive contact with a substrate () to be cooled. The cooling process thus operates similarly to a liquid cooling process, but with a higher mean logarithmic heat transfer temperature difference, which allows lower temperatures of the substrate () to be achieved and makes possible a better heat transition coefficient, since the refrigerant is present as wet vapor. A corresponding arrangement is likewise described.
