Radijator toplinske cijevi je visoko{0}}učinkovit radijatorski uređaj s jedinstvenim karakteristikama odvođenja topline. To jest, ima visoku toplinsku vodljivost, a raspodjela temperature duž aksijalnog smjera između dijela za isparavanje i dijela za hlađenje je ujednačena i uglavnom jednaka.
The thermal resistance of the heat sink is determined by the thermal conductivity of the material and the effective area in the volume. When the volume of a solid aluminum or copper radiator reaches {{0}}.006m³, increasing its volume and area will not significantly reduce the thermal resistance. For discrete semiconductor devices that dissipate heat on both sides, the thermal resistance of an air-cooled all-copper or all-aluminum heat sink can only reach 0.04 degree /W. The heat pipe radiator can reach 0.01 degree /W. Under the condition of natural convection cooling, the performance of the heat pipe radiator can be improved by more than ten times than that of the physical radiator.
