New -type pitted skin heat exchange tube

The utility model relates to a trade the heat pipe technique field, especially relate to a new -type pitted skin heat exchange tube, include the body, the surface of body is equipped with the circularshape and caves in, and the internal surface of body is equipped with the circular shape arch in corresponding sunken position, and sunken and bellied surface is the arcwall face. The utility model discloses pipe inner wall is last to set up a plurality of circular archs, has increased the turbulent flow effect of flow media in the geminate transistors, can the internal flow media of riser with the heat transfer efficiency of body. In addition, circular sunken on the body can impel the torrent to change the emergence of twisting on the one hand, reduces the flying dust granule and to the collision probability of tube wall face, reaches the purpose that lightens wearing and tearing, and on the other hand also can make the difficult fluid separation of emergence of turbulent boundary layer,reduces the resistance th
