1. Tubular (also known as shell-and-tube, tube-tube) heat exchangers are the most typical partition wall heat exchangers. It has a long history of industrial application, and it still dominates all heat exchangers so far status. The tube heat exchanger is mainly composed of a shell, a tube bundle, a tube plate, and a head. The shell is mostly round, with parallel tube bundles inside, and the two ends of the tube bundle are fixed on the tube plate. ’

 

2. The heat exchanger is made of high-quality 304 anti-corrosion stainless steel, and the unique heat dissipation design of the pipeline ensures the maximum amount of heat exchange. Different specifications can be selected according to different needs, and the installation is simple.

 

3. Two fluids that exchange heat in a tube heat exchanger-one that flows in the tube and its stroke is called the tube side; one that flows outside the tube and its stroke is called the shell side. The wall surface of the tube bundle is the heat transfer surface. In order to improve the heat supply coefficient of the fluid outside the tube, a certain number of horizontal baffle baffles are usually installed in the shell. The baffle not only prevents the fluid from short-circuiting and increases the velocity of the fluid, but also forces the fluid to cross the tube bundle multiple times in accordance with the prescribed path, which greatly increases the degree of turbulence. Commonly used baffles are round and disk-shaped, the former is more widely used... Every time the fluid passes through the tube bundle in the tube, it is called a tube pass, and every time it passes through the shell, it is called a shell pass. In order to increase the speed of the fluid in the tube, appropriate partitions can be set in the heads at both ends to divide all the tubes into several groups on average. In this way, the fluid can pass through a part of the tube and return to the tube bundle multiple times at a time, which is called multi-pass. Similarly, in order to increase the flow velocity outside the pipe, a longitudinal baffle can be installed in the housing to make the fluid pass through the housing space multiple times, which is called multi-shell side. In the tube heat exchanger, the temperature of the shell and the tube bundle are also different due to the different temperature of the fluid inside and outside the tube.
