Application characteristics of removable plate heat exchanger

Now, plate heat exchanger has the characteristics of high heat transfer efficiency, small heat loss, small footprint, easy installation and cleaning, long service life and so on. The Dragon Boat Festival is coming soon, the merchants have also dished out promotions to attract customers, plate heat exchanger has to usher in a wave of sales..

In general, the relative flow of fluid in the heat exchanger is generally two kinds of downstream and upstream. At the same time, the temperature difference between the two fluids at the entrance is the largest, and it decreases gradually along the heat transfer surface. When the temperature of the inlet and outlet of the cold and hot fluid is constant, when the two fluids have no phase change, the average temperature difference is the lowest. The temperature distribution of the two fluid along the heat transfer surface is more uniform than that in the reverse flow.

Plate heat exchanger is composed of many stamping corrugated plates at certain intervals, and the framework and pressing screw pressed by overlapping, gasket around, and in the plate and gasket four corner holes are formed in the fluid distributing and collecting pipe. In this way, the cold and hot fluid can be separated in a reasonable way, and the flow can be respectively arranged on both sides of each plate.

                                     
At present, the heat transfer coefficient of plate heat exchanger is times higher than that of tube heat exchanger under the condition of the same pressure loss, which covers an area of 1/3 of the tube heat exchanger, and the heat recovery rate can reach more than 90%.
