HEAT TRANSFER STEADY AND TRANSIENT CHARACTERISTICS IN FLAT PLATE MICRO HEAT PIPE

摘要

Recently, the newly developed flat type micro heat pipe (μHP) attracts attention, because of easy installation in PC and the assurance of the enough contact area. In this research, an experimental study is made to investigate the heat transfer steady characteristics of this heat transfer device in detail and finally, a prediction method of maximum heat transfer capacity is proposed. In addition to this experiment, since the operation of heat pipe starts from ambient temperature in practice, the study of transient heat transfer characteristic is carried out.
