A plate heat exchanger is a high-efficiency heat exchanger consisting of a series of metal plates with a certain corrugated shape stacked together. Thin rectangular channels are formed between the plates for heat exchange. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange. They are characterized by high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure drop, its heat transfer coefficient is 3-5 times higher than that of a tube heat exchanger, the footprint is one-third that of a tube heat exchanger, and the heat recovery rate can be as high as 90% or more. Plate heat exchangers are mainly divided into two categories: frame plate heat exchangers (dismountable plate heat exchangers) and brazed plate heat exchangers. The plate types mainly include three types: chevron corrugated plate heat exchangers, horizontal flat corrugated plate heat exchangers, and blister plate heat exchangers.
Plate heat exchangers are classified according to their structure: demountable plate heat exchangers (also called plate heat exchangers with gaskets), welded plate heat exchangers, spiral plate heat exchangers, and plate-coil heat exchangers (also called honeycomb heat exchangers).
According to process applications, there are different names: plate heaters, plate coolers, plate condensers, plate preheaters;
According to the process combination, they are divided into single-pass plate heat exchangers and multi-pass plate heat exchangers;
According to the flow direction of the two media, they are divided into co-current (parallel flow) plate heat exchangers, counter-current plate heat exchangers, and cross-flow (cross-flow) plate heat exchangers, the latter two being more commonly used;
According to the size of the flow passage gap, they are divided into conventional gap plate heat exchangers and wide gap plate heat exchangers;
According to the corrugations, plate heat exchangers have more detailed classifications, which will not be elaborated here. Please refer to: Corrugated Forms of Plate Heat Exchanger Plates.
According to whether they are complete sets of products, they can be divided into single-unit plate heat exchangers and plate heat exchanger units.
