High efficiency pockmarked pipeIt refers to the heat exchange tube that strengthens the inner and outer surfaces of the ordinary smooth heat exchange tube, so that the overall heat exchange effect is significantly improved.
The strengthening form refers to processing various shapes (spiral scale teeth, protrusions, grooves, etc.) on the inner and outer surfaces of the heat exchange tube by extrusion, rolling, rolling, etc. to change the flow field distribution of the liquid at the wall surface, form turbulent flow, or improve the convection effect. At the same time, the inner and outer surfaces are processed in physical form to extend the inner and outer surfaces to increase the heat exchange area of the inner and outer surfaces, improve the heat exchange coefficient of the heat exchange tube, and improve the overall heat exchange effect obviously.
1. Outer wall pattern, smooth inner wall.
2. Inner and outer wall pattern.
3, the inner wall pattern outer wall smooth and other types of high heat pipe.
