Effect of inclination on the operating performance of flat plate LHP
By changing the internal capillary core structure to improve the performance of the loop heat pipe and reduce the volume of the loop heat pipe,the liquid reservoir is eliminated,the traditional long rectangular steam channel is changed to the shape of Tesla valve,and the evaporator inlet and outlet are set on both sides of the evaporator.The start-up performance and running characteristics of the heat pipe at different inclination angles were studied.The results show that the existence of inclination can reduce the start-up time of the loop heat pipe and reduce the temperature of the evaporator compared with the operation of 0° inclination,and there is no significant difference in the start-up characteristics under the condition of inclination.With the increase of power,the thermal resistance of loop heat pipes with different inclination angles decreases,and only when the inclination angle(below 10°)is low,there is a larger thermal resistance.With the increase of inclination angle,the thermal resistance of loop heat pipes does not change greatly with the change of power.
