Product Description
Channel Spacing Spiral-plate Heat Exchanger Design,Spiral plate heat exchanger compact structure, the unit volume to provide a large heat transfer surface, such as the diameter 1500mm high 1200mm spiral plate heat exchanger heat transfer surface up to 130m2. Fluid in the spiral plate allows high flow rate, and the flow of fluid along the spiral, the stagnation layer is thin, so the heat transfer coefficient, heat transfer efficiency. In addition, due to large flow rate, dirt is not easy to stay.

There are three main types of flows in a spiral heat exchanger:
  1. Counter-current Flow: Fluids flow in opposite directions. These are used for liquid-liquid, condensing and gas cooling applications. Units are usually mounted vertically when condensing vapour and mounted horizontally when handling high concentrations of solids.
  2. Spiral Flow/Cross Flow: One fluid is in spiral flow and the other in a cross flow. Spiral flow passages are welded at each side for this type of spiral heat exchanger. This type of flow is suitable for handling low density gas, which passes through the cross flow, avoiding pressure loss. It can be used for liquid-liquid applications if one liquid has a considerably greater flow rate than the other.
  3. Distributed Vapour/Spiral flow: This design is that of a condenser, and is usually mounted vertically. It is designed to cater for the sub-cooling of both condensate and non-condensables. The coolant moves in a spiral and leaves via the top. Hot gases that enter leave as condensate via the bottom outlet.

Self Cleaning
SHEs are often used in the heating of fluids that contain solids and thus tend to foul the inside of the heat exchanger. The low pressure drop lets the SHE handle fouling more easily. The SHE uses a "self cleaning" mechanism, whereby fouled surfaces cause a localized increase in fluid velocity, thus increasing the drag (or fluid friction) on the fouled surface, thus helping to dislodge the blockage and keep the heat exchanger clean. "The internal walls that make up the heat transfer surface are often rather thick, which makes the SHE very robust, and able to last a long time in demanding environments.They are also easily cleaned, opening out like an oven where any build up of foulant can be removed by pressure washing.
