The plate heat exchanger consists of a set of corrugated metal plates with holes on the plate for the two liquids for heat transfer to pass through. The metal plate is installed in a frame with a fixed plate and a movable compression plate, and is clamped with a clamping bolt. The plate is provided with a sealing gasket, which seals the liquid channels, and guides the fluid to alternately flow into the respective channels. So how to choose the heat exchanger plate?
After identifying the heat exchanger area, the plate needs to be selected. Currently, most heat exchanger manufacturers use herringbone corrugated plates. A few use flat corrugated boards. Generally, a herringbone corrugated board can withstand higher pressures. And the heat transfer coefficient of the herringbone corrugated plate is higher than that of the horizontal corrugated plate. Therefore, when the heat exchanger has a high pressure or requires a high heat transfer coefficient, a herringbone corrugated plate is required. When the heat transfer coefficient and pressure resistance of the heat exchanger are low and system resistance is required, a flat corrugated plate type should be selected.
