孔径递变复合毛细芯的蒸发特性研究
|
摘要
本文对沿工质流动方向孔径递增和孔径递减的两种复合毛细芯进行了蒸发实验研究。结果发现:粒径较大的粉末烧结制备的毛细芯的平均孔径较大;相比于孔径递增的毛细芯,孔径递减的毛细芯表现出更好的换热特性和更低的表面温度。
Heat transfer experiments were carried out on composite wicks for loop heat pipe.Along the flow direction of working fluid,the pore diameter of B1 wick is decreasing,while B2 wick's is increasing.The results show that the average diameter of wick sintered with larger particle size is larger.Compared to the pore-increasing wick,the pore-decreasing wick exhibits better heat transfer characteristics and lower surface temperature.
