Description

A fluid channel having a narrow interval is formed between the two channels, and two types of fluids such as liquid-liquid and liquid-gas are alternately passed through the channel to perform heat exchange. It realizes high thermal efficiency by dramatically increasing the heat transfer area and is suitable for downsizing, and is widely used as a heat exchanger for refrigeration equipment, hot water equipment and the like.
