Experimental Investigation of Heat Transfer Characteristics of the Heat Pipe

The rapid development of electronic industries and increasing processing speed of components, decrease the heat transfer surface area. This generates terribly high heat fluxes, leading to massive temperature rises. To remove the heat flux from the components, heat pipes are being used, now a days. The reliability of electronic components decreases by 10% , for every increasing 2°C raise, above normal operating temperature. Therefore, it's necessary to develop a replacement reasonably sink, to satisfy those necessities, which ought to have the next heat transfer performance, lighter weight and smaller volume. Heat pipe may be a promising candidate, to satisfy the preceding thermal management challenges, within the future. In this paper, two heat pipes were studied through experiment exploitation deionised water, because of the operating fluid. The wick used in the heat pipes is made of SS304 material, with 100 mesh and 200 meshes, respectively. The heat pipes were positioned at totally different angles 00, 450, 900 with horizontal. Experiments were conducted with the natural convection, forced convection condenser cooling, with different heating fluxes. The thermal resistances of heat pipe, operating with forced convection cooling, with 200 mesh at 90o inclination is 53%, lower than the heat pipe operating at horizontal at 50W heat input. The heat transfer coefficient of heat pipe, operating at 45o angle is 71% higher than heat pipe operating at horizontal position, with forced convection cooling with 200 meshes. The effective thermal conductivity of heat pipe, operating at 45o is 47% higher, the heat pipe operating with forced convection cooling, with 200 mesh at horizontal position with 50W heat input.
