The working principle of plate heat exchanger?
The heat transfer plate heat exchanger is composed of many corrugated, at regular intervals, the heat exchange equipment removable by pressing the rubber gasket. The plate assembly, the two groups are alternately arranged between the plate and the rubber sealing strip board adhesive fixed, its role is to prevent fluid leakage and to form a net shaped channel narrow between the two plates, heat exchange plate pressed into various corrugated plates, in order to increase the heat exchange area and rigid, and can make the the formation of fluid turbulence in low flow crash, in order to achieve the effect of heat transfer enhancement. Four corner holes of the plate form a fluid distribution pipe and a drainage pipe, and the two heat exchanging media respectively flow into the respective channel, form a counter flow or flow through each plate to exchange heat.
The characteristics of plate heat exchanger:
(1) small size, small area;
(2) high heat transfer efficiency;
(3) flexible assembly;
(4) low consumption of metal;
(5) heat loss is small;
(6) removal, cleaning and maintenance;
(7) heat exchanger is sealed around the shortcomings of long, easy to leak, can only use temperature lower than 150oC, under less pressure, small amount of processing, once found the plate to open the cleaning fouling
