Jacketed Heat Exchanger

The heat exchanger is made by installing a jacket on the outer wall of the container and has simple structure. But its heating surface is limited by the vessel wall, and the heat transfer coefficient is not high. In order to improve the heat transfer coefficient and make the liquid heated evenly, the agitator can be installed in the kettle. When cooling water or heating agent without phase change is passed into the jacket, spiral partition or other measures to increase turbulence can also be set in the jacket to improve the heat transfer coefficient on one side of the jacket. In order to supplement the lack of heat transfer surface, snake tube can also be installed inside the kettle. Jacketed heat exchangers are widely used for heating and cooling reaction processes.
