Internal Grooved Copper Tube | Internal thread copper tube

Internal grooved copper tube/Internal thread copper tube refers to the internally grooved copper with a smooth outer surface and a certain number of regular threads on the internal surface.

Internal Grooved copper Tube production process

There are continuous or intermittent spiral grooves on the inner surface of the tube, which can increase the contact area and change the flow mode of the refrigerant in the tube. The water is cooled outside the tube through the flow and evaporation of the refrigerant in the tube. The heat transfer coefficient in the tube is the same as that of a light tube. 1.5-2 times that the heat transfer capacity is remarkable. The outer surface of the tube can also be processed with corrugated spiral grooves to expand the scope of use. At the same time, there are also grooves in the tube that are parallel to the tube's radial direction, that is, the spiral angle is zero degrees, which can be used for heat pipe radiators. There are smooth sections and lengths at both ends that can be made according to user requirements. The maximum processing length is 7m.

Advantages of Internal Grooved copper Tube:

Due to the increase in the internal surface area of the internally threaded copper tube, its thermal conductivity is better than that of the smooth tube.

Main applications of Internal Grooved copper Tube:

Commercial air-conditioning heat exchangers, central air-conditioning dry-type evaporators, electronic products and heat pipe radiators for solar installations, etc.
