Abstract: The cooling system may dehumidify and cool the indoor air by using the ejector, the ejector membrane, the evaporation chamber, and the indoor dehumidifying membrane. In addition, the coefficient of performance of the cooling system may be improved by cooling the refrigerant using evaporation latent heat generated in the evaporation chamber by the suction force of the ejector and cooling the indoor air using the refrigerant. In addition, by using solar heat to generate high-temperature and high-pressure steam and supply the generated steam to the ejector, energy use efficiency may be improved. In addition, since the temperature of the steam generated in the steam generating portion may be lowered by arranging and using the two first and second ejectors in multiple stages, energy efficiency may be further improved by reducing the consumption of the heat source required for steam generation.

Abstract: The present application provides a novel water cooling radiator with a detachable water pump and a built-in fan, which enables outside air to enter a cooling housing from air inlet holes in an upper end of the cooling housing and be discharged from air outlet holes in a lower end of the cooling housing, so that the air discharged from the air outlet holes can dissipate heat from and cool down various electronic components such as MOS tubes and memory chips around the motherboard and CPU, thereby improving the heat dissipation efficiency and prolonging the service life of the motherboard. A pump is connected externally to the radiator, which makes the installation and connection more convenient and the performance better.

Abstract: A radiator system uses an innovative passive control scheme in combination with dependable mechanical design features to meet or exceed the requirements for orbital applications. The disclosed radiator system is unique because we target an extremely high turndown ratio of 200:1 with an entirely passive two-phase pumped loop using ammonia as the working fluid. Sections of the radiator will selectively freeze to assist the turndown, and the mechanical design of the radiator can handle the high pressures experienced during such freezing and thawing events.
