An Experimental Investigation on Thermal Performance of Heat Pipe
要約
The conducted comprehensive study involves the rigorous testing of cylindrical heat pipes integrated with screened mesh. The primary focus is on evaluating their characteristics and
performance using water as a working fluid at various inclination angles, yielding significant findings. The results
indicate a clear correlation between an increase in both heat
input and inclination angle below 30°, leading to a notable reduction in thermal resistance and a simultaneous
enhancement in effective thermal conductivity. Remarkably, in
the case of a horizontal heat pipe, the effective thermal
conductivity reached its maximum value of 6050 W/m°C at a
heat input of 60 W. Furthermore, the study uncovered a
compelling observation regarding the effective thermal
conductivity, which demonstrated an increase of approximately
15 times greater than that of a copper rod for inclination angles below 30°. Apart from this, a phenomenon termed as dry-out has been observed at an inclination angle of 40° above a power input of 30 W.
