China Suppliers Spiral Plate Heat Exchanger Factory: High-Efficiency Non-Detachable Design for Optimal Heat Transfer
Description
A spiral plate heat exchanger is a heat exchanger made up of two parallel metal plates rolled into two spiral channels, where the cold and hot fluids exchange heat through the spiral plate walls. There are two types of spiral plate heat exchangers: detachable and non detachable.
Spiral plate heat exchangers have the advantages of small volume, compact equipment, high heat transfer efficiency, and low metal consumption. They are suitable for dry liquid, gas liquid, and gas gas convection heat transfer, steam condensation and liquid evaporation heat transfer, as well as industries such as chemical, petroleum, pharmaceutical, mechanical, electrical, environmental, energy-saving, and requiring heat conversion.
Structure performance
- It is formed by rolling two plates, forming two uniform spiral channels. The two heat transfer media can perform full countercurrent flow, greatly enhancing the heat transfer effect. Even with two small temperature difference media, the ideal heat transfer effect can be achieved.
- The connecting pipe on the shell adopts a tangential structure with low local resistance. Due to the uniform curvature of the spiral channel, there is no significant turning of the liquid flow in the equipment, resulting in low overall resistance. Therefore, the design flow rate can be increased to have higher heat transfer capacity.
- The end face of the spiral channel of the Type I non detachable spiral plate heat exchanger is sealed by welding, thus having high sealing performance.
- The structural principle of Type II detachable spiral plate heat exchanger is basically the same as that of non detachable heat exchanger, but one of the channels can be disassembled for cleaning, making it particularly suitable for heat exchange with viscous and precipitated liquids.
- The structural principle of the Type III detachable spiral plate heat exchanger is basically the same as that of a non detachable heat exchanger, but its two channels can be disassembled for cleaning, making it suitable for a wide range of applications.
- When a single device cannot meet the usage requirements, multiple devices can be combined for use, but the combination must comply with the following regulations: parallel combination, series combination, and the spacing between devices and channels is the same. Hybrid combination: one channel in parallel and one channel in series.

Frequently Asked Questions
What is a spiral plate heat exchanger?
It is a heat exchanger made of two parallel metal plates rolled into two spiral channels. Cold and hot fluids flow through these channels and exchange heat through the spiral plate walls.
What are the main types of spiral plate heat exchangers?
There are detachable and non-detachable types. Specifically, Type I is non-detachable (welded end face), Type II has one channel that can be disassembled, and Type III allows both channels to be disassembled for cleaning.
What are the core advantages of these heat exchangers?
They offer small equipment volume, high heat transfer efficiency, low metal consumption, and compact layout. They also facilitate countercurrent flow, maximizing heat transfer even with small temperature differences.
Which industries and applications are they suitable for?
They are ideal for dry liquid, gas-liquid, and gas-gas convection heat transfer, steam condensation, and liquid evaporation. They are widely used in chemical, petroleum, pharmaceutical, mechanical, electrical, environmental, and energy-saving industries.
Can multiple spiral plate heat exchangers be used together?
Yes, when a single unit is insufficient, multiple devices can be combined in parallel, in series, or in a hybrid configuration (one channel in parallel, one in series), provided the device and channel spacing are consistent.
