How To Choose A Good Heat Exchanger
Jun 15, 2017

In industrial production, in order to process the needs of the process, often carried out a variety of different heat transfer process: such as heating, cooling, evaporation and condensation. Heat exchangers are used to carry out these heat transfer processes by which heat can be transferred from a higher temperature fluid to a lower temperature fluid to meet the production needs.

The actual use of the heat exchanger in a variety of types and forms, usually by structure and material can be divided into:

1. Tubular plate tube heat exchanger;

2. Tubular fixed tube plate heat exchanger;

3. Floating head heat exchanger;

4. U-tube heat exchanger;

5. spiral plate heat exchanger;

6. Plate heat exchanger;

7. Umbrella plate heat exchanger;

8. Tubular graphite heat exchanger;

9.YKA-type round hole graphite heat exchanger;

10. Rectangular block hole graphite heat exchanger;

11. Tubular graphite falling film absorber;

12. Glass-lined heat exchanger;

13. Engineering plastic heat exchanger;

14. Glass heat exchanger and so on.

In the selection of heat exchangers, the factors considered are many, such as materials, pressure. Temperature, humidity difference, pressure drop, scaling, fluid status, application, maintenance and cleaning. The range of adaptation of the various structural types is different, and some structural patterns are good in some cases, but in other cases they are not satisfactory or can not be used at all. Therefore, in the selection should be carefully analyzed all the requirements and conditions, in many of the constraints of the factors should be fully considered, to find out the main contradiction, given a proper solution. Heat exchanger selection to consider a lot of factors, but summed up, the choice of heat transfer equipment should meet at least the following requirements:

1. Ensure that the heat transfer conditions specified in the process are achieved.

2. Strong enough and reliable structure.

3. make in manufacturing, installation and inspection.

4. Economically reasonable. A variety of heat exchangers have its own characteristics, and the clarification of these features later will help us determine the optimum conditions for the form of heat exchangers.
