Heat Transfer Efficiency and Resistance Requirements of Spiral Plate Heat Exchanger
- Apr 08, 2018 -

The heat transfer efficiency of the spiral plate heat exchanger during the operation is very high. Under normal circumstances, the heat transfer efficiency of the spiral plate heat exchanger will be 1-3 times that of the tubular heat exchanger. There is no flow dead zone in the single channel with equal section, and the disturbance of flow by the distance column and spiral channel reduces the critical Reynolds number of the fluid.The heat transfer coefficient of the spiral plate heat exchanger can reach 3000W/(m2.K) when the water and water heat exchange.

The spiral plate heat exchanger recovers low-temperature thermal energy to a certain extent, When the equipment is produced, it is mainly composed of two rolls. When the preheating and recycling are performed, the low-temperature heat energy can be fully utilized, and the entire equipment has high operational reliability. The end face of the spiral channel of the detachable spiral plate heat exchanger is welded and sealed, mainly because of the high sealing performance, so that the two working media can be effectively prevented from mixing.

Spiral plate heat exchangers have a low resistance, and their equipment takes over the housing mainly using a tangential structure, a relatively low pressure loss, and its equipment handles large volumes of steam or gas.In the production of self-cleaning brush, because the medium is spiral flow, dirt is not easy to deposit;It is easy to clean and can be flushed with steam or alkaline solution. It is simple and easy to use. It is suitable for installing cleaning devices. The medium can take a single channel, allowing higher flow rates than other heat exchangers.

Spiral plate heat exchangers can be used in multiple combinations.When a single device cannot meet the requirements for use, multiple units can be used in combination.However, the following requirements must be met when combining: Parallel combination, series combination, equipment and channel spacing are the same.Mixed combination: One channel is connected in parallel and one channel is connected in series.
