1. High heat transfer efficiency (good performance)
It is generally believed that the heat transfer efficiency of spiral plate heat exchangers is 1-3 times higher than that of tube-and-tube sheet heat exchangers. Single channels with uniform cross-section do not have flow dead zones, and the disturbance to flow caused by fixed-distance columns and spiral channels reduces the critical Reynolds number of the fluid. In water-water heat exchange, the heat transfer coefficient of spiral plate heat exchangers can reach 3000W/(㎡·K).
2. Effective recovery of low-temperature heat energy The spiral plate heat exchanger, made of two rolled plates, is used for waste heat recovery, making full use of low-temperature heat energy
3. Strong operational reliability
The end faces of the spiral channels in the non-detachable spiral plate heat exchanger are sealed by welding, thus ensuring high sealing performance and preventing the two working media from mixing
4. Low resistance
The connecting pipe on the shell adopts a tangential structure. It has relatively low pressure loss and is suitable for handling large volumes of steam or gas. Due to the spiral flow of the medium, it has self-cleaning capabilities, making it less prone to dirt deposition. It is easy to clean, as it can be flushed with steam or alkali solution. This simplicity makes it suitable for installing cleaning devices. The medium flows through a single channel, allowing for higher flow rates compared to other heat exchangers 5. Can be used in combination with multiple units When a single device cannot meet the usage requirements, multiple devices can be used in combination, but the combination must comply with the following regulations: parallel combination, serial combination, and the same spacing between devices and channels. Mixed combination: one channel in parallel and one channel in series.
