Heat pipe is a heat transfer element with extremely high thermal conductivity, invented in 1964 in the United States Los Alamos National Laboratory (Los Alamos National Laboratory) and in the late 1960s reached the peak of the theoretical research in the 1970s began to be applied in large quantities in the industrial field. It passes heat through the vapor and liquid phase change of the work material in the totally enclosed vacuum tube, which has extremely high thermal conductivity, up to hundreds of times of the thermal conductivity of pure copper, and has the reputation of "thermal superconductor". The heatpipe CPU cooler is designed to provide a strong performance with no heatpipe air-cooled cooler.
