Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a composite heat exchanger. Background Art

[0002] When the existing composite heat exchanger is in use, the heat exchange of the device adopts a fan to directly inject cold air and water vapor for heat exchange. The heat exchange contact area is small, the heat loss is large, and multiple fluids of different properties cannot be used for heat exchange at the same time when in use. The heat exchange structure for miscible fluids and immiscible fluids is relatively complex, and the heat exchange efficiency is low. At the same time, when heat exchange is performed, the heat exchange tube bundle has large thermal stress, the life of the heat exchange tube bundle is short, and the liquid flow inside the heat exchange tube bundle is slow, affecting the heat exchange efficiency. In the process of transmission, metal pipes are relied on, which is not only expensive, but also has the problem of transmission loss. Therefore, we redesigned a composite heat exchanger.
