文章摘要: Surface structure of condenser for heat column plays a vital role on its heat transfer performance; micro groove surface roughness is beneficial to the enhancement of condensation and heat transfer performance. The exprimentexperiment machining method of manufacturing micro grooves on condenser surface for heat column is designed introduced in this paper; a finite element model machining the condenser for heat column by plough- extrusion (P-E) tool is established,P-E process is simulated using the Deform software; Forming forming process and manufacturing mechanism of micro grooves are analyzed. Experimental results show that feed and P-E depth play important role on surface morphology of micro grooves on condenser , V-shaped grooves are formed when machining ringed grooves on the surface of condenser, U- shaped grooves are formed between two adjacent V- shaped grooves, there are bumps at two end of V- shaped groove,which form fins. Orthogonal micro grooves are formed on the surface of
