Heat Transfer Characteristics of Inclined Evaporator Section for Separate Type Heat Pipe

Heat transfer characteristics are studied for an inclined evaporator section of a separate type heat pipe. The wall temperature distribution and heat transfer regularity of the inclined evaporator are obtained. Emphases are placed on the effects of inclination angle, heat flux and quantity of actuating medium to heat transfer. Better heat transfer could be obtained for an inclined evaporator as compared with the vertical evaporator. The empirical dimentionless correlation of heat transfer coefficient is obtained using regression of the experimental data.
