Description

Technical Field

[0001] The utility model relates to the technical field of heat transfer plates, and particularly relates to a heat transfer plate for water condensation recovery. Background Art

[0002] Heat transfer plates are mostly applied to plate heat exchangers, which play an important role in many industrial productions such as chemical industry, petroleum, power, food and others. A plate heat exchanger is an energy-saving device that realizes heat transfer between materials among two or more gases at different temperatures. It enables heat to be transferred from a gas at a higher temperature to a gas at a lower temperature to meet the requirements of process conditions, and is also the main device for improving energy utilization efficiency.

[0003] At present, plate heat exchangers have been applied to the field of water vapor condensation, also known as condensate recovery field. Plate heat exchangers have the advantages of high heat transfer area under the same volume and high heat transfer efficiency under the same area. However, most common heat transfer plates are of flat plate structure, or grooved and gully plate surface structures. Although they have high heat transfer efficiency, they are not conducive to the recovery of water droplets after water condensation. After water vapor condensation, a uniform water film will form on the plate surface and adhere to the plate, affecting the heat transfer efficiency. Therefore, in the field of water vapor condensation, although common heat transfer plates achieve efficient heat exchange, the water film formed by condensate water affects the condensation of other water vapor.

[0004] In view of this, the utility model proposes a heat transfer plate for water condensation recovery. Content of the Utility Model
