How to produce a coil heat exchanger
As we all know, coil heat exchangers are very important part of a air cooled chiller and air source heat pumps. How does a factory produce coil heat exchangers ? Below are total 9 different procedures to maintain superior quality products. 1. Material preparation (copper tube, end plate, side plate, middle support plate, short U-head, gas / liquid tube, liquid distribution tube) 2. Fin stamping (punching machine, fin die) mainly produces corrugated fins or louver fins according to requirements, including multiple rows and multiple sections of fins. 3. Copper tube cutting (bending machine, cutting machine) according to the need to discharge long U-tube, straight tube. 4. String tube, pre-assemble the fin, copper tube and end plate together manually 5. Tube expansion (horizontal tube expander, portable tube expander) is mainly to expand the pre-assembled copper tube and finned copper tube into a coil with high heat exchange effect, and com...
