Technical Field

[0001] The utility model relates to the technical field of heat exchangers, and more particularly to a stainless steel plate heat exchanger. Background Art

[0002] A plate heat exchanger is a highly efficient heat exchanger composed of a series of stacked, corrugated metal plates. Thin rectangular channels are formed between the plates, through which heat is exchanged. Plate heat exchangers are ideal for liquid-to-liquid and liquid-to-vapor heat exchange. They offer high heat transfer efficiency, minimal heat loss, a compact and lightweight structure, a small footprint, wide application, and a long service life.
