Background
The heat pipe technology is a heat transfer element called a "heat pipe" invented by George Grover (Los Alamos) national laboratory in the United states of Amersham (1963), which fully utilizes the heat conduction principle and the rapid heat transfer property of a phase change medium, and rapidly transfers the heat of a heating object to the outside of a heat source through the heat pipe, and the heat conduction capability of the heat pipe exceeds that of any known metal.
The heat pipe technology is widely applied to the industries of aerospace, military industry and the like before, since the heat pipe technology is introduced into the radiator manufacturing industry, the design thought of the traditional radiator is changed, a single radiating mode of obtaining a better radiating effect by simply relying on a high-air-volume motor is eliminated, the heat pipe technology is adopted to enable the radiator to obtain a satisfactory heat exchanging effect, and a new world of the radiating industry is opened up. At present, the heat pipe is widely applied to various heat exchange equipment, including the nuclear power field and the computer field, such as the waste heat utilization of sea water desalination and the like.
