Heat exchanger tubing with yarn turbulator |
| abstract |
A process and the product thereof, wherein thermoplastic tubing for use in a heat exchanger is extruded with a multifilament yarn (20) inside to act as a turbulator. The extrusion is started with a small rod or a lead-in wire (21) pushing the end of the yarn through the die (11) into the tubing (14) to a place where it adheres to the inner wall of the tubing (14) as it is cooling, then the yarn (20) is pulled into the tubing (14) as it is extruded. The part of the tubing with the lead-in wire is cut off, leaving tubing with efficient turbulation. |
