the plate heat exchanger is composed of two parts: the external frame and the heat exchange plate, the core part of which is the heat exchange plate, which is usually pressed by metal sheet, and the plate body has regular corrugated shape.
First, it has high efficiency and low heat loss. under the same conditions, the heat transfer coefficient is 3-5 times higher than that of tubular heat exchanger;
Second, the floor area is small. Compared with the tubular heat exchanger of the same specification, the floor area is only 1/3 of the former.
