Spiral plate heat exchanger can make full use of low temperature thermal energy

Date:2020-03-06

The spiral plate heat exchanger consists of two parallel steel plates rolled into spaced spiral flow channels. Cover plates are welded at both ends of the spiral plate. The hot and cold fluids flow in the two flow channels, respectively.

Performance characteristics:

1. High heat transfer efficiency (good performance)

It is generally believed that the heat transfer efficiency of the spiral plate heat exchanger is 1 to 3 times that of the tube and tube heat exchanger. There is no dead zone of flow in the single channel of the same section. The disturbance of the flow by the fixed distance column and the spiral channel reduces the critical Reynolds number of the fluid. The heat transfer coefficient of the spiral plate heat exchanger can reach 3000W / (㎡ · K).

2.Efficiently recover low-temperature heat energy

Spiral plate heat exchanger is made of two rolls to recover waste heat and make full use of low-temperature heat energy.

3.Strong operation reliability

The end face of the spiral channel of the non-detachable spiral plate heat exchanger is welded and sealed, so it has a high sealing performance and ensures that the two working media are not mixed.

4.Low resistance

The nozzle on the housing adopts a tangential structure. Relatively low pressure loss, handling large-capacity steam or gas; self-cleaning ability, due to the spiral flow of the medium, dirt is not easy to deposit; easy cleaning, can be washed with steam or lye, simple and easy, suitable for installing cleaning devices; The medium goes in a single channel, allowing higher flow rates than other heat exchangers.

5.can be used in combination

When a single device cannot meet the requirements for use, multiple combinations can be used, but the combination must meet the following requirements: parallel combination, series combination, equipment and channel spacing are the same. Hybrid combination: One channel is connected in parallel, and one channel is connected in series.
