Product description:
The spiral plate heat exchanger is simple and precise in structure. It is made up of two or four long metal sheets wound around the same center. The plate is welded with a fixed distance column to form two or four completely independent ones. Spiral flow path with a rectangular cross section.

The spiral plate heat exchanger can be manufactured from any metal material with good welding and cold bending properties. The metal materials used in the production of spiral plate heat exchangers include carbon steel, stainless steel and alloy steel. The heat exchanger can withstand an operating pressure of 4.0 MPa and an operating temperature of 400 °C. The width of the spiral plate ranges from 300 mm to 2000 mm: the flow path spacing is from 5 mm to 30 mm.

As a professional manufacturer of spiral plate heat exchangers in China, ARD has excellent design solutions, rich manufacturing experience, qualified tooling equipment and a wide range of application fields.

The spiral plate heat exchanger is a heat transfer device with high heat transfer efficiency which realizes heat transfer by spiral passage, and is widely used in chemical production. The working principle is that when two fluids with different temperatures flow into the passage of the heat exchanger from both sides of the pipe wall, the two fluids are in countercurrent contact through the pipe wall. Heat is transferred from the hot fluid to the pipe wall and then from the pipe wall to the cold fluid to achieve structural features that allow the fluid to reach a turbulent state at a lower velocity, thereby enhancing heat transfer. The equipment is made of sheet metal, so it can reduce costs when mass production is organized.

Structure and performance:
1. The equipment is made up of two rolls, forming two uniform spiral channels. The two heat transfer media can carry out full countercurrent flow, which greatly enhances the heat transfer effect, even if the two small temperature difference media can reach the appropriate 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 passage is uniform, the liquid does not have a large steering in the device, and the total resistance is small, so that the design flow rate can be improved to make it more comparable. High heat transfer capacity.
3. The end face of the spiral passage of the type I non-removable spiral plate heat exchanger is welded and sealed, thus having a high sealing property.
4. The structure principle of the Type II detachable spiral plate heat exchanger is basically the same as that of the non-removable heat exchanger, but one of the channels can be disassembled and cleaned, especially for heat exchange with viscous and precipitated liquid.
5. The structure principle of the type III detachable spiral plate heat exchanger is basically the same as that of the non-removable heat exchanger, but the two channels can be disassembled and cleaned, and the scope of application is wide.
6. When a single device cannot meet the requirements for use, it can be used in combination, but the combination must meet the following requirements: parallel combination, series combination, equipment and channel spacing are the same. Hybrid combination: one channel is connected in parallel and one channel is connected in series.
