Title: Hiroyoshi Sugawara: Innovator in Heat Exchanger Technology
Introduction
Hiroyoshi Sugawara is a notable inventor based in Anjo, Japan. He has made significant contributions to the field of heat exchanger technology, holding a total of 5 patents. His innovative methods focus on improving the efficiency and functionality of aluminum alloy heat exchangers.
Latest Patents
Sugawara's latest patents include a method of surface treating aluminum alloy base bodies of heat exchangers. This method enables a uniform and quick etching procedure, allowing for the formation of a corrosion-resistant chemical conversion coating. The process involves pretreating the aluminum heat exchanger base body with an aqueous pre-treating liquid with a pH of 9.0 or less, followed by etching with an aqueous alkaline solution with a pH of 9.0 or more. The etched base body is then subjected to a chemical conversion treatment or a hydrophilicity-enhancing treatment. Another significant patent is for an aluminum alloy heat exchanger that resists tobacco odor impregnation. This invention features an organic hydrophilic coating layer that enhances hydrophilicity and reduces the absorption of tobacco odorous components.
