Title: Innovations by Chung K Chan
Introduction
Chung K Chan is a notable inventor based in Los Angeles, CA. He has made significant contributions to the field of cooling technologies, holding a total of 3 patents. His work focuses on enhancing the efficiency of cooling systems, which has important applications in various industries.
Latest Patents
One of his latest inventions is the multistage pulse tube cooler. This innovative design allows for a portion of the heat from each successively lower-temperature pulse tube cooler to be rejected to a heat sink other than the preceding higher-temperature pulse tube cooler. This approach substantially improves the overall efficiency of the multistage cooler. Traditional multistage pulse tube coolers impose a large cooling load on higher-temperature coolers, which reduces overall efficiency.
Another significant patent is the Joule Thomson refrigerator. This bi-directional refrigerator features a simple construction at the cold end. It allows compressed gas to flow in either direction through the Joule Thomson expander valve, becoming liquid and captured in a container in direct contact with the heat load. The valve is designed to respond to the temperature of the working fluid, maintaining a generally constant mass flow throughout its operation.
