PERFORMANCE TESTING METHOD FOR HIGH TEMPERATURE HEAT PIPE

摘要

PURPOSE: To calculate a heat transporting characteristic value of a heat pipe under a condition of an operating temperature range by a method wherein an evaporating part of a high temperature heat pipe is heated and held within an operating temperature range, a cooling pipe having a circular sectional area is wound around an outer circumference of a condensing part in a predetermined clearance and the cooling medium is flowed within the cooling pipe and cooled. ;CONSTITUTION: An evaporating part 12 arranged within a heating furnace 15 for a high temperature heat pipe 11 is heated, a flow rate adjusting valve 18 is opened and cooling water in a water storing tank 16 is flowed within a cooling pipe 14. Potassium contained in the working fluid is resolved within the heated evaporating part 12, further heated and evaporated. Then, the working fluid moves within the heat pipe 11 toward the condensing part 13, is contacted with an inner circumferential surface of the condensing part 13 cooled and kept at a low temperature with cooling water flowing within the cooling pipe 14 and then condensed. The cooling water absorbing heat becomes hot discharged water and then the water is recovered in a hot discharged water tank 17. Accordingly, it is possible to calculate a heat transporting amount of the high temperature heat pipe 11 in reference to an amount of and a temperature of the hot discharged water.;COPYRIGHT: (C)1996,JPO
