Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange devices, in particular to a gas-liquid heat exchange device. Background Art

[0002] The principle of heat exchange is mainly based on the law of heat exchange, that is, when two objects with different temperatures come into contact with each other, energy transfer will occur. Specifically, the high-temperature object releases heat to the low-temperature object, while the low-temperature object absorbs energy from the high-temperature object. When the two objects reach thermal equilibrium, the heat released is equal to the heat absorbed. The working principle of the heat exchanger further explains this process. In a heat exchanger, there are two different fluid flow channels, namely the hot fluid and the cold fluid. The two fluids cross-flow in the heat exchanger, and the heat is transferred from the high-temperature area to the low-temperature area through heat conduction and convection heat transfer.
