چکیده انگلیسی
An experiment was carried out to study the effect of liquid filling ratio, inclination angle, and type of working fluid on the performance of a novel flat-plate micro heat pipe (FPMHP). The FPMHP is developed based on a multiport micro/minichannel flat tube, capable of the advantages such as the simple manufacturing process, flexible structure, good isothermal performance and heat transport with a long distance. Results shows that a filling ratio has a significant effect on thermal performance, and a FPMHP with a filling ratio of 20% has the best performance. The temperature distribution along the adiabatic section showed nearly no difference between two measuring points, indicating that the FPMHP is able to employed as a high-efficiency heat transfer equipment of phase change. FPMHP performance was improved remarkably when the inclination angle increased from 0° to 20° due to the effect of gravitational and buoyancy force, but the performance difference was negligible when the inclination angle increased from 20° to 90°. For different working fluids, the higher transmission factor, the better working fluids thermal performance. Thus, the FPMHP using methanol has the best performance, with a minimum thermal resistance of 0.18â¯K/W and a maximum thermal conductivity of 8539â¯W/mK, respectively.
