Pressure issues in tubular heat exchangers
Thread Content
I have a question: the pressure at the hot water inlet of the heat exchanger is very high. I need to achieve a lower pressure at the outlet, while also improving the heat exchange efficiency. How should such a heat exchanger be designed, and which parameters, shapes, or flow patterns need to be changed?
To improve heat transfer efficiency, the heat transfer area must be increased; to achieve a lower pressure at the outlet, the outlet diameter can be enlarged.
1. Increase the outlet diameter to achieve pressure relief； 2. It is recommended to relieve pressure at the water inlet first, and then introduce the water into the heat exchanger, thereby reducing the design pressure rating of the heat exchanger.
