Is the cold and hot interface of plate heat exchanger interchangeable?

The plate heat exchanger has the best effect in the single side countercurrent heat transfer, that is to say, when the primary side (heat source side) and the secondary side (heated side) are on the same side, and the inlet and outlet direction is opposite, the heat transfer effect is better.

If the direction of exchange is on the same side and the reverse flow is maintained, but the direction of import and export is exchanged, the heat exchange effect is not different. If it is the collusion of cold and hot water, it is wrong and cannot operate normally.

Plate heat exchanger is a new type of high efficiency heat exchanger, which is composed of a series of corrugated metal sheets. Thin rectangular channels are formed between various plates, through which heat is exchanged. Plate heat exchanger is a kind of equipment for liquid-liquid and liquid vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small floor area, convenient installation and cleaning, wide application and long service life.

Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, its floor area is one third of that of the tubular heat exchanger, and its heat recovery rate can reach more than 90%.
