Spiral plate heat exchanger consists of two parallel steel plates rolled into spiral flow channels that are separated from each other. The two ends of the spiral plate are welded with cover plates. Cold and hot fluids flow in two separate channels.

Performance characteristics of spiral plate heat exchanger:

1. High heat transfer efficiency

It is generally believed that the heat transfer efficiency of spiral plate heat exchangers is 1-3 times that of tubular heat exchangers. There is no flow dead zone in a single channel with equal cross-section, and the disturbance of the flow by the fixed distance column and spiral channel reduces the critical Reynolds number of the fluid. The maximum heat transfer coefficient of the spiral plate heat exchanger during water water heat exchange can reach 3000W/(㎡) K）。

2. Effectively recover low-temperature thermal energy

Spiral plate heat exchanger is made of two coils for waste heat recovery, fully utilizing low-temperature heat energy.

3. Strong operational reliability

The end face of the spiral channel of the non detachable spiral plate heat exchanger is sealed by welding, thus having high sealing performance and ensuring that the two working media do not mix.

4. Low resistance

The connecting pipe on the shell adopts a tangential structure. Relatively low pressure loss, capable of handling large volumes of steam or gas; Has self-cleaning ability, as its medium flows in a spiral shape and dirt is not easily deposited; Easy to clean, can be rinsed with steam or alkali solution, simple and easy to implement, suitable for installing cleaning devices; The medium travels through a single channel, allowing for a higher flow rate than 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 combined for use, but the combination must comply with the following regulations: parallel combination, series combination, and the same equipment and channel spacing. Mixed combination: one channel in parallel and one channel in series.
