热管散热器工作原理

 

Working Principle of Heat Pipe Radiator

 

热管散热器运行时，其蒸发段吸收热源(功率半导体器件等) 产生的热量，使其吸液芯管中的液体沸腾化成蒸汽。带有热量的蒸汽就从热管散热器的蒸发段向其冷却段移动，当蒸汽把热量传给冷却段后，蒸汽就冷凝成液体。冷凝的液体便通过管壁上吸液芯的毛细管作用返回到蒸发段，如此重复上述循环过程不断地散热。

 

When the heat pipe radiator runs, the evaporation section absorbs the heat generated by the heat source (power semiconductor devices, etc.), which makes the liquid in the core tube boil into steam. Steam with heat moves from the evaporation section of the heat pipe radiator to its cooling section. When the steam passes heat to the cooling section, the steam condenses into liquid. The condensated liquid is returned to the evaporation section through the capillary action of the suction core on the wall of the tube, thus repeating the above-mentioned circulation process to continuously dissipate heat.
