The refrigerant flow in traditional bow-shaped turnback flow heat exchanger moves in “Z” path. The new spiral flow design in spiral turn-back plate heat exchanger changes the status and form of refrigerant, thus increasing heat exchange efficiency. The main characteristics of spiral turn-back plate heat exchanger are as below:
- High heat transfer coefficient (20%-40% increase);
- Full coverage of heat exchange. Without Dead Heat;
- Obvious decrease of pressure drop in the shell (around 45% drop pressure under the same flow velocity);
- Few impurities as no retention area in the shell;
- Better anti-vibration.
