Manufactured from two rolls, it forms two uniform helical channels. The two heat transfer media can flow in full counter-current, significantly enhancing the heat exchange efficiency. Even for two media with small temperature differences, ideal heat exchange effects can be achieved.
2. The tangential structure is adopted for the接管 on the housing, resulting in low local resistance. Due to the uniform curvature of the helical channel, there is no significant redirection of the liquid flow within the equipment, leading to low total resistance. Consequently, the design flow rate can be increased, thereby enhancing the heat transfer capability.
The Type I non-detachable spiral plate heat exchanger features a sealed end face with welding, resulting in high sealing performance.
4. The Type II removable spiral plate heat exchanger operates on the same 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 fluids.
5. The III-type removable spiral plate heat exchanger has a basic structure and principle similar to that of non-removable heat exchangers, but its two channels can be disassembled for cleaning, making it more versatile in application.
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 combination, series combination, and equal spacing between equipment and channels. Mixed combination: one channel in parallel and one channel in series.
Structural Principles:
Detachable plate heat exchangers consist of many corrugated thin plates pressed together at certain intervals, sealed around with gaskets, and overlapped with frames and clamping screws.
The four corner holes of the plates and spacers form fluid distribution and collection pipes, while also logically separating the cold and hot fluids, allowing them to flow through the channels on each plate's sides, facilitating heat exchange through the plates.
