The plate type and its structural parameters have great influence on the heat transfer of plate heat exchanger. The different plates will make a significant difference in the flow of fluid in the channel between plates. For example, the flow in the plate heat exchanger of a herringbone plate is a typical network three-dimensional flow (see figure as below), and the flow in the plate heat exchanger with horizontal straight corrugated sheets is two-dimensional.

The three - dimensional flow of V-shape corrugated plate fluid in the inter plate channel.

Same plate type to the different structural parameters of corrugated, also can make flows have differences, and make it suitable for heat exchanger under different working conditions, as the chart type plate of herringbone Angle different heat transfer coefficient is also different.
