3D打印毛细芯与底座间隙对环路热管性能影响
Effect of Clearances between 3D-Printed Wick and Heating Plate on Thermal Performance for LHP
摘要
Abstract
In order to reduce the heat leakage in the evaporator and improve the heat performance of loop heat pipe(LHP),the clearance between the 3D-pringted composite wick and the heating plate was changed.LHP was assembled by three combined methods of the wick and the heating plate with no clearance,1 mm clearance and 2 mm clearance respectively,and their start-up and operating performance were experimentally studied.It was showed that the start-up time of the LHP with clearance will be prolonged due to the increase of the clearance.The suppression of heat leakage was most significant,when the clearance was 2 mm,the composite wick evaporation layer was 200 μm,and transportation layer was 100 μm.At the same time,the power was 180 W,the evaporator wall temperature was 96.7℃,and the heat transfer coefficient was 73 681 W/(m2·K).The increase in clearance had no significant inhibitory effect on heat leakage,while the composite wick evaporation layer of was 200 μm,and the transportation layer of was 100 μm.In conclusion,the influence of composite wick on the heat transfer performance of LHP can be controlled by changing of the clearance between the composite wick and the heating plate.关键词
