Summary

DESCRIBES A STUDY TO CLARIFY THE EFFECT OF CENTRIFUGAL FORCE ON THE PERFORMANCE OF A REVOLVING HEAT PIPE WHOSE AXIS IS PARALLEL TO THE AXIS OF ROTATION. VARIOUS KINDS OF HEAT PIPES UP TO 3 M IN MAXIMUM LENGTH HAVE BEEN TESTED WITHIN THE RANGE OF 196 M/S2. THE EXPERIMENT INDICATES THAT MAXIMUM HEAT TRANSPORT CAPABILITY INCREASES WITH THE INCREASE IN THE NUMBER OF REVOLUTIONS WHILE THE APPARENT INTERNAL HEAT TRANSFER COEFFICIENT DECREASES WITH IT. IT IS FOUND THAT THE INTERNAL STRUCTURE OF THE HEAT PIPE REMARKABLY AFFECTS THE PERFORMANCE OF REVOLVING HEAT PIPES. THEREFORE, ADEQUATE INTERNAL STRUCTURE MAKES IT POSSIBLE TO TAKE ADVANTAGE OF INCREASING MAXIMUM HEAT TRANSPORT CAPABILITY BY REVOLUTION WITHOUT DECREASE OF THE APPARENT INTERNAL HEAT TRANSFER COEFFICIENT.
