Finned tube heat exchanger

Product Introduction:

Fin type heat exchanger is a commonly used equipment for heating, cooling, or heat exchange, particularly suitable for handling high-temperature, high-pressure, and high-speed fluids.

Working principle: A finned heat exchanger is composed of many metal fins and pipes. They are usually arranged in parallel and connected together to form a finned tube bundle. The pipes inside the finned tube bundle provide a channel for the working fluid to transfer heat from one medium to another. Among them, fins are metal products in the shape of wing plates, which are bonded to the surface of the tube through mutual connection or welding, increasing the thermal conductivity area of the tube and thus increasing the heat transfer rate; Pipes are channels for the flow of media, thereby transferring heat or cold to the media flowing through them. When two different temperature media flow through the finned tube bundle, heat is transferred to the pipeline through the fins and further transferred to the other medium. The effectiveness of heat exchange depends on factors such as the number and structure of fins, fluid velocity, and the thermal conductivity of the medium. In summary, finned heat exchangers utilize finned tube bundles to increase the surface area for heat transfer between media, achieving fast and efficient heat transfer and exchange.

Shell and tube heat exchanger has the characteristics of:

1. good sealing performance,
2. elimination of leakage,
3. high heat exchange efficiency,
4. easy maintenance,
5. long corrosion life and so on.

Structure and Heat Transfer Principle

The cooler consists of the following parts .Heat transfer principle: heat and cold for heat transfer of two kinds of fluid, one in the pipe flow, known as pipe fluid;The otherflow outside the tube is called shell – side fluid.In order to improve the heat transfer coefficient of the fluid outside the tube, several baffles are usually installed in the shell.The baffle can increase the fluid velocity of the shell side, force the fluid to cross the tube bundle several times according to the prescribed route, and enhance the degree of fluid turbulence.The heat exchange pipes can be arranged in equilateral triangle or square on the tube plate.The equilateral triangle has compact arrangement, high turbulence and high heat transfer coefficient.The square arrangement makes it convenient to clean the outside of the tube and is suitable for the fluid that is easy to scale.
