Copper Nickel Pitted Surface Tube

The pit/convex structure of the pitted tube not only enhances heat transfer without excessively increasing the pressure drop, but also makes it less likely to generate dirt and dust, which reduces wear on the tube wall and also has a certain pressure-bearing strength.

Due to the existence of periodic convex cells on the inner surface of the pockmarked tube, the steam motion state changes, which intensifies the fluid disturbance and thins the boundary layer. At the same time, the synergy between the velocity field and the temperature field on the steam side is improved, achieving enhanced heat transfer on the steam side.

A pitted heat exchange tube, including a tube body formed by bending and welding metal strips, characterized in that the outer surface of the tube body is provided with a plurality of convex pillars arranged at intervals, and each of the convex pillars respectively includes: The column body is formed by protruding from the outer surface of the pipe body along the radial direction of the pipe body. The cross section of the column body perpendicular to the radial direction is rhombus, and the rhombus shape A diagonal line is parallel to the axis of the tube body; and a column cap, the column cap is integrally formed on the top of the column body, the column cap includes: overlapping with the top in the radial direction an overlapping portion, and an extension portion integrally surrounding the overlapping portion.

1) Lithium bromide refrigeration unit.

2) Condensers and evaporators on air conditioning and refrigeration equipment.

3) Heat exchangers, oil coolers and general-purpose heat exchangers in thermal power stations.

4) Various heat exchangers, dryers and heaters in the waste heat recovery system.

Choosing a good copper hemp tube manufacturer mainly depends on two points: one is that the quality of the product must pass, because the quality of the product directly affects the use of customers, the copper hemp tube is a vulnerable product, so the wear life directly affects customer satisfaction Spend!

The second is the price. In terms of price, JALE copper inner grooved tube maintains an absolute advantage in the market, especially for dealers. Under the environment of the new normal of the market economy, demand is declining, and only a more advantageous manufacturer can hold profits. To survive, we use automated mechanized production to effectively control the process to improve production efficiency, thereby reducing production costs, so we now have an absolute price advantage compared with other products!
