How to determine the size and angle of the imported board heat exchanger board?

The size and angle of plate heat exchanger plate are mainly based on the following points:

1. Media type.

The type of media here is mainly based on special media. For example, if the photovoltaic industry uses mortar, the viscosity of mortar is high and the flow rate is slow. Therefore, when selecting the design, we will give priority to small angle to improve the flow rate.

2. Flow

For example, the steam flow of steam-water heat exchanger is too large, so we should give priority to the small angle first, because the steam flow itself is very fast, plus the current large flow, considering that the heat of steam is fully utilized, the small angle is the first choice.

3. Heat exchange area

Some heat exchangers need to be replaced due to their age, but they can also provide heat exchange area without knowing any parameters. Calculate the number of channels according to the heat exchange area, and calculate whether the existing channels are satisfied according to the average value of the medium flow in the plate heat exchanger, so as to determine the size angle of the plate heat exchanger.
