Heat dissipation performance of heat pipe radiator

Heat pipe radiator is a kind of high efficiency heat dissipation device, which has unique heat dissipation characteristics. That is, it has a high thermal conductivity, and its temperature distribution between the evaporating section and the cooling section is uniform and substantially equal in the axial direction.
The thermal resistance of the heat sink is determined by the thermal conductivity of the material and the effective area within the volume. When the volume of the solid aluminum or copper radiator reaches 0.006m ³, increasing its volume and area cannot significantly reduce the thermal resistance. For discrete semiconductor devices with double-sided heat dissipation, the thermal resistance of an air-cooled all-copper or all-aluminum heat sink can only reach 0.04°C/W. The heat pipe radiator can reach 0.01 ℃/W. Under natural convection cooling conditions, the performance of the heat pipe radiator can be improved by more than ten times than that of the solid radiator.
