- product introduction:Inner Grooved Copper Tubes were produced in the 1970s. The inner surface of the copper tube is processed with some quantity and specification of thread, compared to smooth copper tubes of the same specification, which increases the heat exchange area and improves the thermal conductivity of refrigeration, and increase the turbulence of the fluid inside the tube, reduce the thickness of the laminar bottom layer of the fluid, effectively reduce thermal resistance, and improve heat transfer efficiency. Throughout the development history from 1970s to 1980s, the Addendum Angle from 53-90 ° , developed to 40 ° gradually from the early to the late 1980s. And the Helix Angel was around 18 °, which has been improved the conversion efficiency than before from 1970s to 1980s. Later, the technological innovation guided by Chinese enterprises gradually shifted towards higher heat transfer efficiency, such as thin high teeth, high low teeth, and crossed teeth with large helix angles. With the continuous progress of society and the increasing emphasis on resources and environmental protection, many inner Grooved Copper Tubes have been used and promoted constantly. Among them, large helix angle and thin high tooth is the outstanding one. Compared with ordinary teeth (Addendum Angle 40-53 ° ), thin high teeth (Addendum Angle ≤ 30 °) have a larger inner surface area and an enhanced Grigorian effect, which promotes better heat transfer performance of copper tubes in condensation and evaporation states. It is used in air conditioning and refrigeration equipment, automotive air conditioning systems, electronic equipment, various cooling systems of large mechanical equipment, and precision equipment and so on widely.
