Radijator toplotne cijevi je visoko{0}}radijatorski uređaj s jedinstvenim karakteristikama odvođenja topline. Odnosno, ima visoku toplotnu provodljivost, a raspodela temperature duž aksijalnog pravca između sekcije za isparavanje i sekcije za hlađenje je ujednačena i suštinski 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.
