ABSTRACT:
A heat pipe is provided for transferring heat from a heat source to a heat sink. A check valve, which is operated by very low pressure, is placed in the vapor channel of a heat pipe and allows vapor to flow in a forward direction from the heat source to the heat sink. In the event that the heat sink becomes hotter than the heat source, vapor flow will reverse direction but will be blocked by the check valve.
