Title: Innovations of Hans-Joachim Koetz
Introduction
Hans-Joachim Koetz is a notable inventor based in Nuertingen, Germany. He has made significant contributions to the field of heat exchanger technology, holding a total of 2 patents. His work focuses on innovative designs that enhance the efficiency and functionality of heat exchangers.
Latest Patents
Koetz's latest patents include a light-weight cross-flow heat exchanger unit. This invention comprises a plurality of corrugated film elements stacked in alternating layers, with the ridges and grooves of each film element extending transversely to those of an adjacent film element. Flat divider elements are interposed between each pair of adjacent film elements, and the structure is enclosed by a coating that bonds the elements together to form a rigid heat exchanger block. The film elements may be made of non-metallic material, and the coating may consist of a curable, synthetic resinous material. Another significant patent involves arrangements for directing flow through one or more modular, cross-flow heat exchanger units. These units have primary and secondary flow channels of predetermined lengths and are arranged in a housing with defined inlet and outlet openings. This design ensures that the portion of each flow path over which intensive heat exchange occurs is no longer than the length of the associated flow channels.
