摘要

A heat exchanger is described which comprises a tubular element which forms a closed duct through which a flowing medium suitable for heat transfer flows, and which is welded to a heat-collecting or heat-dissipating plate. The tubular element and the plate are fastened to one another in such a way that a point contact exists between the two elements over the length of the tubular element at points separated from one another. The two elements are welded to one another at these points. The plate can be perforated in order to improve the air flow over the plate.
