Description

Technical Field

[0002] High-temperature plate heat exchangers typically refer to the plates used in plate heat exchangers operating under high-temperature conditions. A plate heat exchanger is a highly efficient heat exchanger composed of a series of metal plates with a specific corrugated shape stacked together. Thin rectangular channels are formed between the plates, allowing heat exchange to occur. Plate heat exchangers are ideal devices for liquid-liquid and liquid-vapor heat exchange. They feature high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. Under the same pressure loss conditions, their heat transfer coefficient is 3-5 times higher than that of tubular heat exchangers, their footprint is one-third that of tubular heat exchangers, and their heat recovery rate can reach over 90%.
