The Structural Characteristics and Working Principle of Spiral Plate Heat Exchangers

Manufactured from two rolls, it forms two even spiral channels, allowing both heat transfer media to flow in a fully counter-current manner, significantly enhancing the heat exchange efficiency. Even with small temperature difference media, it achieves ideal heat exchange results.

        2. The transition on the housing is designed with a tangential structure, which minimizes local resistance. Due to the uniform curvature of the helical channels, the fluid flow within the equipment experiences minimal directional changes, resulting in lower total resistance. Consequently, the design flow rate can be increased, enhancing the heat transfer capability.

        The I-type non-detachable spiral plate heat exchanger features a sealed end face with welding, thus offering high-sealing properties.

        4. The Type II removable spiral plate heat exchanger operates on the same structural principle as non-removable heat exchangers, but one channel can be disassembled for cleaning, making it particularly suitable for heat exchange with sticky or sediment-containing liquids.

        The III-type removable spiral plate heat exchanger has a structure and principle similar to non-removable heat exchangers, but its two channels can be disassembled for cleaning, making it more widely applicable.

        6. When a single piece of equipment does not meet the usage requirements, multiple units can be combined. However, the following regulations must be adhered to when combining: parallel connection, series connection, and equal spacing between equipment and channels. Mixed connection: one channel in parallel and one channel in series.
