Spiral heat exchanger
Spiral heat exchangers in horizontal and vertical design are widely used for heat transfer processes between various liquids, vapors and gases in the oil, petrochemical, chemical, gas and other industries. This type of heat exchanger is successfully used to work with highly viscous and contaminated working media, as well as media with a high content of mechanical impurities.
Description and design
The heat exchanger consists of heat exchanger sheets twisted into a spiral and placed in a housing. The sheets are welded on one side to the central manifold, and on the other to the cylindrical body. The pins between the sheets help to form channels of constant cross-section. The body can be all-welded, or have removable covers for the possibility of mechanical cleaning of the heat exchanger channels.
