Аннотация

An experimental investigation of flat and cylindrical miniature heat pipes (mHP) with different wick structures (sintered powder, mesh structure, wire bundle) was performed. Experimental results and predicting simulation software verification, particularities of testing are presented. Modelling, design, manufacturing and testing of cylindrical miniature copper/water heat pipe with diameter 4 mm and length 200 mm with copper sintered powder wick for notebook CPU and laser diodes thermal control was done. The Qmax for such a heat pipe is near 50 W.
