[0002] Plate heat exchanger is a kind of high-efficiency heat exchange equipment, mainly composed of a series of corrugated metal sheets stacked together, with thin rectangular channels formed between these corrugated metal sheets, so that heat can be exchanged through these channels. Plate heat exchanger is particularly suitable for heat exchange between liquid-liquid and liquid-steam, with high heat exchange efficiency, small heat loss, compact structure, small space occupation, easy installation and cleaning, wide application and long service life.
