Heat pipe heat sink is composed of sealing tube, suction core and steam channel. The suction core is surrounded on the wall of the sealed tube and impregnated with saturated volatile liquid. The liquid can be distilled water, ammonia, methanol or acetone. The heat pipe heat sink filled with liquid such as ammonia, methanol and acetone still has good heat dissipation ability at low temperature. When the heat pipe heat sink is running, its evaporation section absorbs the heat generated by the heat source ( power semiconductor device, etc.), making the liquid in its wick boil to steam. The heated steam moves from the evaporating section of the heat pipe heat sink to its cooling section, where it condenses into a liquid. The condensed liquid is then returned to the evaporation section through the capillary action of the suction core on the wall, so as to repeat the above cycle process of continuous heat dissipation.
Compared with other traditional heat dissipation modes, heat pipe heat sink has the following advantages
● Its thermal conductivity is almost 200 times better compared to copper. This also allows the heat sink to be a lot smaller than we are used to.
● Heat pipe heat sink Small size and light weight;
● High heat dissipation efficiency, can simplify the heat dissipation design of electronic equipment, such as variable air cooling for self-cooling;
● Smaller heat sink reduces the weight of the luminaire dramatically. This reduces transportation costs as well as the amount of other materials needed.
● The Heat Pipe effectively transfers heat from the heat source and as a result makes the cooling faster than ever.
Goldconn offers heat pipe manufacturing in all shapes, sizes, and performance characteristics for use in its custom heat sink designs. Their high thermal conductivity, ease with which they can be bent and shaped, and exceedingly long life make heat pipes an ideal upgrade to solid metal heat sinks or, in some cases, an alternative to pumped liquid cooling systems. Unlike many Chinese manufacturers, Goldconn uses oxygen-free copper in its Heat Pipes, which means that their lifetime is over 20 years.
