The spiral wound tube heat exchanger is a type of shell-and-tube heat exchanger that retains the traditional high-pressure resistance characteristics of shell-and-tube designs while offering advantages such as countercurrent flow, multi-stream arrangement, low terminal temperature difference, compact structure, high heat transfer efficiency, strong thermal compensation capability, and ease of maintenance. It is particularly suitable for high-pressure gas applications that demand both efficient heat transfer and high-pressure tolerance.
The main technical features are as follows:
1. Specifically designed for high-pressure multi-fluid heat transfer, capable of handling complex process media within a single heat exchanger.
2. Compact structure with a large heat transfer area per unit volume, delivering significant thermal performance within a small footprint.
3. Excellent thermal compensation performance, as the spiral wound tubes can partially self-adapt to thermal expansion, thereby enhancing reliability under temperature fluctuation conditions.
4. Flexible configuration of winding layers to optimize flow field distribution on both the tube side and shell side, enabling pressure drop control and flow field matching.
5. Adopts a staggered spiral winding arrangement to enhance turbulence, improve heat transfer performance, and achieve a high overall heat transfer coefficient.
6. Multi-nozzle atomizers can be optionally equipped with ethylene glycol injection to effectively prevent icing or blockage under low-temperature operating conditions.
