This paper describes the fundamental experiments on the heat transport characteristics of the flat-plate type thermosyphon. The thermosyphon consists of two aluminum plates (evaporator and condenser sections) and an acrylic spacer sandwiched between them. HFE-7200 is enclosed as the working fluid. A sinter sheet made of small copper powders is placed inside the thermosyphon to enhance the boiling heat transfer. In the experiment, the heat is applied from a small heat source to a center of the bottom plate, while the top plate is entirely cooled by an air-cooled heat sink. The temperature distributions of the thermosyphon, the heat source and the heat sink are measured by thermocouples. The experimental results confirm that the thermal performance of the present thermosyphon is improved by the sinter sheet and better than the aluminum solid plate of the same size.
