Composition and advantages of jacketed heat exchanger
Jun 03, 2020

Jacketed heat exchanger is a type of plate heat exchanger. It is made of a jacket installed on the outer wall of the container and has a simple structure; however, its heating surface is limited by the wall of the container and the heat transfer coefficient is not high. In order to improve the heat transfer coefficient and make the liquid in the kettle heated evenly, a stirrer can be installed in the kettle. When cooling water or no phase change heating agent is introduced into the jacket, spiral baffles or other measures to increase turbulence can also be provided in the jacket to improve the heat supply coefficient on the side of the jacket. In order to supplement the shortcomings of the heat transfer surface, a snake tube can also be installed inside the kettle. Jacketed heat exchangers are widely used for heating and cooling in the reaction process.

The advantages of jacketed heat exchangers are:

◆Simple structure;

◆Easy to process.

The disadvantages of jacketed heat exchangers are:

◆Small heat transfer area and low heat transfer efficiency.
