FINNED TUBE HEAT EXCHANGER

Finned tube heat exchanger is a common high-efficiency heat exchange equipment, it is through the finned tube as a heat exchange element, the heat transfer between the two media.

1.the working principle: finned tube heat exchanger using the finned tube design, the outer surface of the tube to increase the fins, expanding the surface area in contact with the medium, thereby increasing the heat transfer effect. Strengthen the heat transfer effect. One of the medium in the finned tube flow, called “tube side” or “inside”; another medium in the finned tube outside the flow, called “fin side” or “outside”. The other medium flows outside the finned tube, called the “fin side” or “outside”. Through the finned tube heat conduction, heat transfer between the two media.

2.Structure: finned tube heat exchanger consists of finned tube bundle, shell, inlet and outlet piping, support devices and other components.

3.finned tube bundle: consists of a number of parallel arrangement of finned tubes, usually made of metal, such as aluminum alloy, stainless steel and so on. The fins on the finned tube can be.

The fins on the finned tube can be in the form of straight fins, spiral fins, curved fins and so on.

4.Shell: The shell that carries the finned tube bundle is usually made of metal, such as carbon steel, stainless steel, etc.

The shell has an inlet and outlet aperture and an installation support. Shell with import and export caliber and installation support Points.

5.Import and export piping: connecting the import and export caliber of the medium flow, usually through the flange connection.

6.Supporting device: used to support and fix the finned tube bundle to ensure its stability in the working process.
