Title: Daisuke Nakajima: Innovator in Ejector Technology
Introduction
Daisuke Nakajima is a prominent inventor based in Kariya, Japan. He has made significant contributions to the field of ejector technology, holding a total of 2 patents. His innovative designs focus on improving the efficiency of refrigerant systems.
Latest Patents
Daisuke Nakajima's latest patents include two distinct ejector designs. The first patent describes an ejector body that features a diffuser passage. In this design, an ejection refrigerant is jetted from a nozzle passage and mixed with a suction refrigerant drawn from a suction passage. This mixture is then pressurized through a passage formation member, leading to a gas-liquid separation space where the refrigerant is separated into gas and liquid by centrifugal force. The inlet part of an oil return passage is strategically positioned closer to the outer peripheral side than to the axis center of the passage formation member.
The second patent outlines an ejector that consists of a body part with a depressurizing space. This space allows a refrigerant flowing out of a swirling space to be depressurized. The design includes a suction passage for drawing refrigerant from the external environment and a pressurizing space where a jet refrigerant and a suction refrigerant are mixed and pressurized. A conical passage formation member is arranged inside the body part, and a swirling promotion part is included to enhance the swirling flow of the refrigerant.
