Study on heat transfer characteristics of heat pipe with axial Ω-shaped microgrooves
Heat pipes are devices capable of very high heat transfer and have been widely used in many thermal management applications.Heat pipe with axial Ω-shaped grooves combines a high capillary pumping pressure with a low axial pressure drop in the liquid.An experimental investigation of thermal characteristics of heat pipe with axial Ω-shaped grooves was presented in this paper.The experimental results showed that the work temperatures affect the equivalent heat transfer coefficients obviously,and 20 ℃ is chosen to be the most appropriate working temperature for heat pipe in present study.The working temperature affects the operational characteristic of heat pipe significantly.When the working temperature is 20 ℃,the most efficient working input power is from 80 to 140W.The tilt angles affect the equivalent heat transfer coefficients not so obviously.
