Title: Innovations of Shaowei Zhu in Cryogenic Refrigeration

Introduction

Shaowei Zhu is a prominent inventor based in Kariya, Japan. He has made significant contributions to the field of cryogenic refrigeration, holding a total of 9 patents. His work focuses on improving the efficiency and functionality of refrigeration systems, particularly in cryogenic applications.

Latest Patents

One of his latest innovations is a cryogenic refrigerator that includes a pressure feeding device, a refrigeration device, a high-pressure passage, a low-pressure passage, and at least one heat exchanger. This heat exchanger is designed to refrigerate the refrigerant introduced at the high-pressure passage through heat exchange. Notably, it features an active pressure drop type heat exchanger that reduces the pressure of the refrigerant by a ratio equal to or greater than 5 percent before it enters the refrigeration device. This innovative design enhances the overall efficiency of the refrigeration process.

Another significant patent is for a pulse tube refrigerator, where the refrigeration efficiency has been improved by minimizing on-off valve loss. In this design, a second space in a cylinder member is connected with high-pressure and low-pressure on-off valves. A buffer side on-off valve is strategically placed between the buffer space and the second space. By opening the buffer side on-off valve prior to the other valves, the pressure in the second space can be maintained at an intermediate level, thereby reducing the pressure difference and minimizing on-off valve loss.
