A brief introduction to the classification of Metal Heat Exchanger

Jacketed heat exchanger:
This Heat Exchanger is made by installing a jacket on the outer wall of the container, and has a simple structure; but its heating surface is limited by the container wall, and the heat transfer coefficient is not high. In order to improve the heat transfer coefficient and make the liquid in the kettle evenly heated, it can be installed in the kettle. Install agitator. When cooling water or non-phase change heating agent is passed into the jacket, spiral partitions or other measures to increase turbulence can also be set in the jacket to increase the heat transfer coefficient on one side of the jacket. In order to supplement the lack of heat transfer surface, a coil can also be installed inside the kettle. Jacketed heat exchangers are widely used for heating and cooling in the reaction process.
Immersed snake tube heat exchanger:

This kind of Heat Exchanger is to bend the metal pipe into various shapes suitable for the container and immerse it in the liquid in the container. The advantage of the snake tube heat exchanger is that the structure is simple, can withstand high pressure, and can be made of corrosion-resistant materials; its The disadvantage is that the liquid turbulence in the container is low, and the heat coefficient outside the tube is small. In order to improve the heat transfer coefficient, a stirrer can be installed in the container.
