The spiral plate heat exchanger is made up of two coils to form two uniform spiral channels. The two heat transfer media can carry out full countercurrent flow, which greatly enhances the heat transfer effect.The ideal heat transfer effect with two small temperature difference media.What are the characteristics of spiral plate heat exchangers?
(1) High heat transfer efficiency (good performance)
It is generally believed that the heat transfer efficiency of the spiral plate heat exchanger is 1-3 times that of the tube-and-tube heat exchanger. There is no flow dead zone in the single channel of the equal section, and the disturbance of the flow by the fixed column and the spiral channel reduces the critical Reynolds of the fluid. The heat transfer coefficient of spiral plate heat exchanger can reach 3000W/(m2.K).
(2) Effective recovery of low temperature heat energy
The spiral plate heat exchanger is made up of two coils for waste heat recovery, making full use of low temperature heat energy.
(3) Strong operational reliability
The end face of the spiral passage of the non-removable spiral plate heat exchanger is welded and sealed, so that it has a high sealing property and ensures that the two working media are not mixed.
(4) Small resistance
The connecting pipe on the casing adopts a tangential structure. It has relatively low pressure loss and handles large-capacity steam or gas. It has self-cleaning ability. Because its medium is spirally flowing, dirt is not easy to deposit. Easy to clean.It can be flushed with steam or lye. It is easy to install and is suitable for installing cleaning devices. The medium is single channel, allowing the flow rate to be higher than other heat exchangers
(5) Multiple combinations can be used
When a single device cannot meet the requirements for use, it can be used in combination, but the combination must meet the following requirements: parallel combination, series combination, equipment and channel spacing are the same. Mixed combination: one channel is connected in parallel, one channel is connected in series.
