Working Principle of Heat Pipe Heat Dissipation Structure

The heat pipe radiator consists of a sealed tube, a suction core and a steam passage. The suction core is surrounded by the wall of the sealed pipe and is immersed in a saturated liquid which can be volatilized. The liquid can be distilled water, ammonia, methanol or acetone, etc. Heat pipe radiators filled with liquid such as ammonia, methanol and acetone still have good heat dissipation ability at low temperature. Explosion-proof heat pipe radiator

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.The heat pipe radiator consists of a sealed tube, a suction core and a steam passage.
