Structural Performance Of Spiral Plate Heat Exchangers
May 02, 2026| Composed of two rolled sheets, forming two uniform spiral channels, the two heat transfer media can flow in complete countercurrent flow, greatly enhancing the heat exchange effect. Even with two media with small temperature differences, ideal heat exchange can be achieved.
The nozzles on the shell adopt a tangential structure, resulting in low local resistance. Because the curvature of the spiral channels is uniform, the liquid flow within the equipment does not involve significant changes in direction, resulting in low overall resistance and allowing for higher design flow rates, thus achieving higher heat transfer capacity.
The end faces of the spiral channels in the Type I non-removable spiral plate heat exchanger are welded for sealing, resulting in high sealing performance.
The Type II removable spiral plate heat exchanger has a similar structural principle to the non-removable type, but one channel can be disassembled for cleaning, making it particularly suitable for heat exchange of viscous liquids and liquids with sediment.
The Type III removable spiral plate heat exchanger has a similar structural principle to the non-removable type, but both channels can be disassembled for cleaning, making it suitable for a wider range of applications.
When a single device cannot meet the usage requirements, multiple devices can be used in combination, but the following regulations must be met when combining them: parallel combination, series combination, and equal spacing between devices and channels. Mixed combination: one channel is connected in parallel, and one channel is connected in series.
