MULTI HEAT PIPE APPARATUS COMPRISING AN ALTERNATIVE HEAT PIPE FOR MAINTAINING A COOLING EFFECT, AND A MULTI HEAT PIPE APPARATUS FOR A SATELLITE USING THE SAME

摘要

PURPOSE: A multi heat pipe apparatus comprising an alternative heat pipe for maintaining a cooling effect, and a multi heat pipe apparatus for a satellite using the same are provided to maintain the performance of the satellite by maintaining a cooling effect using an alternative heat pipe even if a heat pipe is not operable.;CONSTITUTION: A multi heat pipe apparatus comprising an alternative heat pipe comprises a main heat pipe(M), an alternative heat pipe (A), and a side heat pipe(S). The main heat pipe contacts with a heat source. The alternative heat pipe contacts with the heat source and the main heat pipe. The side heat pipe contacts with one side of the alternative heat pipe and the main heat pipe. When the main heat pipe is not operable, heat transfer fluid is circulated by the alternative heat pipe to cool the heat source.;COPYRIGHT KIPO 2010
