ترجمة "heat pipe" إلى العربية

A cooling device consisting of a sealed metal tube containing a liquid and a wick. The liquid evaporates at the hot end; the vapor spreads along the tube to the cold end, where it condenses onto the wick; the liquid flows back along the wick to the hot end by capillary action. Heat pipes have been used in Pentium-based laptop computers, which have high cooling requirements and little room for conventional heat sinks.
