Stainless Steel Coil Heat Exchanger

Spiral plate heat exchangers are made of two thin metal plates welded to a dividing baffle (the short plate in the center of the picture) and rolled into a spiral. Two thin metal plates form two spiral channels in the device, and the top and bottom are respectively welded with cover plates or heads. When exchanging heat, the cold and hot fluids enter two channels respectively, and flow strictly countercurrently in the device.

Introduction

Structure and performance of spiral plate heat exchanger
1. The equipment is made of two rolls, forming two uniform spiral channels. The two heat transfer media can flow in full countercurrent, which greatly enhances the heat exchange effect. Even if the two media with small temperature difference
It can also achieve a suitable heat transfer effect.
2. The connecting pipe on the casing adopts a tangential structure, and the local resistance is small. Since the curvature of the spiral channel is uniform, the liquid flows in the equipment without a large turn, and the total resistance is small, so the design flow rate can be increased to make it have a higher High heat transfer capacity.
3. The end face of the spiral channel of the |-type non-detachable spiral plate heat exchanger is sealed by welding, so it has high sealing performance.
4. The structural principle of the detachable spiral plate heat exchanger is basically the same as that of the non-detachable heat exchanger, but one of the channels can be disassembled for cleaning, which is especially suitable for heat exchangers with viscous and precipitated liquids Change.
5. The structural principle of the detachable spiral plate heat exchanger is basically the same as that of the non-detachable heat exchanger, but its two channels can be disassembled for cleaning, and its application range is wider.
6. When a single device cannot meet the requirements of use, multiple devices can be used in combination, but the combination must meet the following regulations: parallel combination, series combination, and the same distance between equipment and channels.
Mixed combination: one channel in parallel, one channel in series.
