Heat exchanger

Heat exchanger

Application range

Shell and tube heat exchanger is a general process equipment for heat exchange. Widely used in chemical, petroleum, electric power, light industry, metallurgy, atomic energy, shipbuilding, aviation, heating and other industrial sectors. Especially in the oil refining and chemical processing device, occupies an extremely important position.

Form of heat exchanger

According to the tube plate and the shell and with part of the form can be divided into fixed tube plate, floating head type, U tube type, eddy heat film etc..

According to the type of heat exchanger tube can be divided into light pipe, corrugated pipe, spiral pipe, pipe, etc..

According to the installation of the form can be divided into two types of horizontal and vertical.

Material of heat exchanger

According to the different media, carbon steel, stainless steel can be used (SUS304, SUS316, SUS316L), copper tube and its special material.

Technology performance

Maximum operating temperature: 350 C maximum working pressure: 10MPa

Main types

Tube plate and shell 1 tube bundles at both ends of the integrated and simple structure, but only suitable for cold and hot fluid temperature difference, and heat exchanger shell operation without the mechanical cleaning process.

The tube plate 2 floating head heat exchanger is freely floating, eliminating the heat stress, and the whole control can be extracted from the shell, easy cleaning and maintenance machinery.

3.U type tube heat exchanger each heat exchange tube is complete U type, both ends are fixed in the same tube plate up and down two zone, with the help of the tube box of the partition into the import and export of room two. The heat exchanger completely eliminates the thermal stress, simple structure than the float, but the tube is not easy to clean.

4 eddy current hot film type heat exchanger using eddy current thermal film heat transfer technology, by changing the motion state of fluid to increase the heat transfer effect, when the medium through the surface vortex tube when strong scour vortex tube surface, thus improving the heat exchange efficiency, up to 10000W/M2 DEG C. At the same time, the structure can realize the functions of corrosion resistance, high temperature resistance, high pressure resistance and anti scaling function.
