Experiment Investigation on Heat Transfer Characteristics of a Novel Gravity-Assisted Heat Pipe Heat Exchanger

Abstract:

Article Preview

A novel gravity-assisted heat pipe with fins was developed. The influences of filling ratio, inclination angle and air velocity at condenser section on the heat transfer characteristics were investigated experimentally. The results show that heat power has an important effect on heat transfer characteristics while inclination angle has little effect on that. The minimum heat transfer resistance is got at the filling ratio equaling about 20%. The heat transfer thermal resistance decreases gradually as the air velocity at condenser section increases.
