1. Plate heat exchanger plates are the core components of plate heat exchangers. Heat transfer between the cold and hot fluids occurs on these plates, making them the primary heat transfer elements of the heat exchanger. Additionally, the plates must withstand the pressure difference between the two sides. Therefore, the selection of suitable plate types and flow channels for plate heat exchanger plates has a significant impact on the operation of the heat exchange equipment, heat transfer efficiency, fluid resistance, and other factors.

Heat exchanger plate Choose:

• The choice of plate types and corrugation patterns for heat exchangers plate should be based on the specific heat transfer conditions and requirements. In situations where there is a large flow rate and a small allowable pressure drop, plates with low resistance should be selected. The selection of removable or brazed plate heat exchangers should be determined based on the pressure and temperature conditions of the heat transfer medium.
• For equipment with a large heat transfer area, it is not advisable to choose plates with excessively small individual plate areas. This is because having too many plates may result in low flow velocity between the plates, leading to a decrease in the overall heat transfer coefficient.

Flow arrangement and flow channels Choose:

• The flow arrangement refers to a group of parallel flow channels in a heat exchanger where a single fluid flows in the same direction. On the other hand, flow channels refer to the passages formed by adjacent plate pairs inside a plate heat exchanger through which the fluid flows. In general, several flow channels are connected in parallel or series to form different combinations of cold and hot fluid passages.
• To ensure that the fluid flows between the plate bundles according to specific requirements, the four corners of the plates are punched and gaskets are applied as per the specifications. The plates are arranged in a regular pattern to form the flow channels, which is known as flow arrangement. The form of flow arrangement should be determined based on heat transfer and fluid resistance calculations, while satisfying the process requirements. When the convective heat transfer coefficients on both sides of the heat transfer surface are equal or close, the heat transfer coefficient can be maximized. Therefore, to achieve better heat transfer performance, it is desirable to make the convective heat transfer coefficients in the cold and hot water flow channels equal or close to each other.
