We often have some new customers who want to help them replace their old heat exchangers. Under normal circumstances, the parameters of the heat exchanger have been blurred. The technicians can also analyze the working conditions provided by the customers. There are three elements for the selection of the angle of the plate heat exchanger. I will summarize it for everyone. I hope it will be helpful to everyone.
1. The type of medium
The type of medium here is mainly based on the special medium. For example, the mortar used in the photovoltaic industry has a large viscosity and a slow flow rate. Therefore, when choosing a design, we will give priority to a small angle so that the flow rate can be increased.
2. Flow
For example, the steam flow of the steam-water heat exchanger is too large, so our first consideration is to choose a large angle first. Because the steam flow rate itself is fast, plus the current large flow, considering that the heat of the steam can be fully utilized, the large angle Is the first choice!
3. Heat exchange area
Some heat exchangers need to be replaced by the whole machine due to their age, but without knowing any parameters, the heat exchange area can also be provided. Calculate the approximate number of channels based on the heat exchange area, and calculate whether the existing channels can be satisfied based on the average flow rate of the medium in the plate heat exchanger, so that the size and angle can also be determined.
