GAS-LIQUID HEAT EXCHANGE DEVICE

WIPO Patent Application WO/2019/153564

A1

A gas-liquid heat exchange device (10), comprising: a first liquid distribution means (20), a second liquid distribution means (30), and a heat exchange assembly (40) connected between the first liquid distribution means (20) and the second liquid distribution means (30). A flow equalization plate (25) and a liquid guide piece (26) are disposed on the first liquid distribution means (20) to equalize liquid inlet flows. Longitudinal fin tubes (41) are disposed on the heat exchange assembly (40). The longitudinal fin tubes (41) are uniformly distributed in an array, and heat sinks (43) on adjacent longitudinal fin tubes (41) are staggeredly arranged to obtain the heat exchange assembly (40) having low wind resistance, large gas heat exchange superficial area and long heat exchange route, so that the entire gas-liquid heat exchange device (10) has uniform liquid distribution, low gas wind resistance, large gas heat exchange superficial area and long heat exchange route and implements heat exchange between gas and liquid by means of counter flows; therefore, the gas-liquid heat exchange device (10) has high heat exchange efficiency.
