Often encountered some new customers are hoping to help them replace their old home heat exchanger, the general situation of the heat exchanger parameters have been blurred, the technicians can also be based on the working conditions provided by the customer to carry out analysis. For plate heat exchanger plate angle size of the choice of 3 elements summarised to you, I hope to help you:
1. The type of medium
Here the type of media is mainly based on the special media to illustrate. For example, the photovoltaic industry away from the mortar, then the viscosity of the mortar itself is large, and the flow rate is slow, so in the choice of design, we will give preference to a small angle, so that the flow rate can be increased.
2. Flow rate
For example, steam heat exchanger, steam flow is too large, then our first consideration is to give priority to the large angle, due to the flow rate of steam itself is fast, coupled with the current large flow rate, taking into account the heat to make full use of steam, large angle is preferred!
3. Heat transfer area
Some heat exchangers due to the age of the whole machine needs to be replaced, but do not know any parameters of the case, provide the heat transfer area can also be. According to the heat transfer area to deduce the approximate number of channels, according to the medium in the plate heat exchanger in the flow rate of the average to calculate the existing channel can meet, so that you can also determine the size of the angle.
