Internal thread pipe series
Technical description:
The inner surface of
is equipped with continuous or intermittent spiral grooves, which can increase the contact area, change the flow mode of the refrigerant inside the tube, and cool the water outside the tube through the evaporation of the refrigerant flowing inside the tube. The heat transfer coefficient inside the tube is 1.5 to 2 times that of the smooth tube of the same specification, and the heat transfer capacity is significant. The outer surface of the pipe can also be processed into corrugated spiral grooves to expand its application range. There are also grooves parallel to the radial direction of the pipe inside the tube, that is, the helix Angle is zero degrees, which can be used for heat pipe radiators. There are smooth sections at both ends and the length can be made according to the user's requirements, with a maximum processing length of 7 meters.
Main application:
Commercial air conditioning heat exchangers, dry evaporators for central air conditioning, heat pipe radiators for electronic products and solar energy installations, etc.
Technical Description
The outer surface of the tube is equipped with continuous spiral integral fins, which have no contact thermal resistance. The height of the fins is over 5mm, and the heat transfer outer surface area is more than 7 times that of the smooth tube of the same specification, demonstrating remarkable heat transfer capacity. Our company can produce fins of this tube type with densities of 5 fins per inch, 7 fins per inch, 8 fins per inch, and 9 fins per inch. The outer diameter is 30-60mm, the fin height is 5-15mm, and the maximum processing length is 7m.
Main applications
1. Gas-gas, gas-water, and gas-oil heat exchangers.
2. Air coolers and heaters in thermal power plants.
3. The cooler and gas dryer of the unit, etc.
