[0002] A microporous heat exchanger is a heat exchange device that uses the gas separation performance of a microporous membrane to achieve heat transfer. Its basic principle is to transfer heat between two gases or liquids at different temperatures through a microporous diaphragm. Under the action of the microporous membrane, the gas or liquid at a higher temperature enters the gas or liquid at a lower temperature through the microporous membrane, thereby achieving the heat transfer effect.
