Heat dissipation principle of heat pipe radiator
Release time:

The heat pipe radiator consists of a sealed tube, a wick and a steam channel. The wick surrounds the wall of the sealed tube and is impregnated with a saturated liquid that can evaporate. Such a liquid may be distilled water, ammonia, methanol, acetone, or the like. The heat pipe radiator filled with ammonia, methanol, acetone and other liquids still has good heat dissipation capacity at low temperatures.
When the heat pipe radiator is running, its evaporation section absorbs the heat source (power semiconductor deviceEtc.) The heat generated causes the liquid in the wick tube to boil into steam. The steam with heat moves from the evaporation section of the heat pipe radiator to its cooling section. When the steam transfers heat to the cooling section, the steam condenses into liquid. The condensed liquid returns to the evaporation section through the capillary action of the wick on the tube wall, thus repeating the above cycle process to continuously dissipate heat.
