Plate heat exchanger is a high-efficiency heat exchanger made up of a series of metal sheets with a certain corrugated shape. The amount of heat transfer in a plate heat exchanger is mainly affected by factors such as temperature, pressure and flow. The use of some technical measures can increase the heat transfer of heat exchange equipment. Under the condition of meeting the original heat transfer, its volume can be reduced, so the heat transfer area of the designed heat exchanger should be as small as possible, so that more heat can be transferred in the rated unit time.
The way to increase the heat transfer effect of the plate heat exchanger is as follows: increase the transfer coefficient, increase the heat transfer temperature difference, expand the heat transfer area, and expand the heat transfer area is the easiest way to increase the heat transfer effect. Large heat exchanger heat transfer temperature difference is one of the commonly used measures to enhance the heat exchange effect of heat exchangers. During the use of the heat exchanger, the pressure of the steam in the tube of the radiant heating panel is increased. During the use of plate heat exchangers, we should consider whether the actual process or equipment conditions allow it. We cannot always pursue the increase of heat transfer temperature difference, but should take into account the rational use of energy in the entire thermal system. The plate heat exchanger is easy to change the heat exchange area or process combination.
