Abstract
Abstract A heat pipe comprising a hermetically sealed hollow body which is filled with a saturated vapor of and a small amount of the condensate of a heat carrying fluid. The heat pipe communicates with the inside of an auxiliary body which also may contain a small amount of the condensate and vapor and which has associated therewith heat sink and heat source means by which the amount of vapor in the auxiliary body and in the hollow body may be regulated to control heat flow in the heat pipe.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
147 words
A controllable heat pipe formed as a main hollow body having therein a saturated vapor of and a boiling condensate of a liquid and an auxiliary hollow body in gaseous communication with the main hollow body and into which said vapor and condensate may be controllably maintained, a heat sink device in heat conducting contact with said auxiliary body for withdrawing heat from the auxiliary hollow body and a heat source for said auxiliary body for supplying heat thereto; the improvement comprising in that said auxiliary body includes therein a plurality of separate spaces containing said vapor and condensate and in that said heat sink device is positioned near one end of said auxiliary hollow body whereby the spaces within said hollow body progressively nearer to said heat sink device will be exposed to lower temperatures than said spaces progressively further away from said heat sink device.
Claim 2
Dependent Claim
147 words
