Three different types of industrial heat exchangers
Apr 09, 2018

From the structural point of view, industrial heat exchangers can be simply divided into three categories. One is a monolithic industrial heat exchanger. It is also one of the most common industrial heat exchangers. It consists of many single heat pipes. And the heat pipe is of the same type. The number of heat pipes depends on the amount of heat transfer.


In order to increase the heat transfer coefficient of the gas, the method of adding fins outside the tube of the industrial heat exchanger is often adopted, so that the number of heat pipes required can be greatly reduced, but the heat transfer effect of the equipment has been significantly increased, and Effectively simplifies the structure of the device.


The other is a separate industrial heat exchanger, which is a heat transfer device that uses the vaporization-condensation of the working medium to transfer energy. Only by separating the heat-receiving part from the heat-releasing part, the heating section and the condensing section are respectively placed in two independent heat exchange fluid channels, and the steam rising pipe is connected with the condensate-falling pipe, so that the hot and cold fluids can be separated from each other. If the remote or cold and hot fluids are absolutely not allowed to be mixed, it is possible to realize the simultaneous heat exchange of a fluid and several fluids.


In addition, the combined industrial heat exchanger is also a commonly used heat exchange device. According to different temperature sections of the heat exchanger, heat pipes filled with different working media are generally divided into high temperature sections and intermediate temperature sections. Three sections of the low temperature section, or two sections of the high temperature section and the low temperature section.


Regardless of which of the above-mentioned industrial heat exchangers, it is to arrange a plurality of heat pipes in accordance with a certain arrangement of rows and columns, bundled in the frame of the housing, and the intermediate section of the heat pipe evaporation section and condensation Segments are separated into cold and hot fluid channels, allowing the heat in the hot fluid to be continuously transferred to the cold fluid.
