The above is about why you should use plate heat exchanger and how to select the type of plate heat exchanger. I hope it will help you!
In the process of production, there is an increase or decrease in the temperature of the medium. The condenser and evaporator have phase change, and the heat exchanger and cooler have no phase change. In the water-water heat exchange of the plate heat exchanger, steam-water heat exchange is a relatively suitable heat exchange equipment, but the first step of using the plate heat exchanger is the heat transfer of the two media.
Today, a customer came. Our technician communicated with him. At first, he said that plate heat exchanger was needed, but he said that the heat exchange of the two media only provided a medium inlet and outlet temperature, and the other, more vaguely, only water heat exchange. He asked whether the plate heat exchanger could do it. Our technical engineer explained that the plate heat exchanger is inter-wall heat transfer, and the channel formed between the plates is sealed by the plate heat exchanger gasket to "guide" the flow of the medium, and the separated cold and hot channels pass through the plate heat exchange.
Therefore, the plate and rubber gasket can be said to be the main factors affecting the heat exchange efficiency, so how to determine the type of plate heat exchanger depends on the temperature and medium type. The main material of rubber gasket is rubber. Although there will be other production links to improve the aging temperature and reduce the compression deformation rate, when the temperature is higher than 160 ℃, we usually consider replacing the rubber gasket with the plate-shell heat exchanger and sealing the two plates by welding.
This is just the beginning of the selection of plate heat exchangers. What type of plate heat exchanger should we use, or should be selected according to the specific operating conditions, so we make customized heat exchanger, because even the heat exchanger used in the same industry will have slight differences in operating conditions, which may be the difference in cost.
