Title: Dennis P Held: Innovator in Heat Exchanger Technology
Introduction
Dennis P Held is a notable inventor based in East Aurora, NY (US). He has made significant contributions to the field of heat exchanger technology, holding a total of 3 patents. His innovative methods have advanced the manufacturing processes of brazed aluminum heat exchangers.
Latest Patents
One of his latest patents focuses on methods of manufacturing brazed aluminum heat exchangers involved in boiling and condensing. This method includes a high-performance nucleate boiling surface bonded with the walls of fin-less boiling passages. The process involves providing a first heat exchanger core subassembly with a joinable end, at least one cooling and one boiling passage, and a first partial finless passage. A second heat exchanger core subassembly is similarly constructed and brazed to the first. The two subassemblies are affixed to form a coupled finless passage, creating a complete heat exchanger core.
Another significant patent is for a heat exchanger that comprises a boiling passage and cooling passage defined by opposite sides of metal walls. This design incorporates layers of brazing material between the metal walls and a spacer member to bond the components together. An enhanced boiling layer (EBL) is included, which consists of metal particles that improve heat transfer by providing nucleate boiling pores. The EBL has a melting temperature higher than that of the brazing material, ensuring durability and efficiency.
