A shell and tube heat exchanger consists of components such as a shell, heat transfer tube bundle, tube plate, baffle plate (baffle), and tube box. The shell is mostly cylindrical, with a tube bundle installed inside, and both ends of the tube bundle are fixed on the tube plate. There are two types of fluids for heat exchange: cold and hot. One flows inside the tube and is called the tube side fluid; Another type of fluid that flows outside the tube is called shell side fluid. To improve the heat transfer coefficient of the fluid outside the tube, several baffles are usually installed inside the shell. The baffle can increase the velocity of the shell side fluid, forcing the fluid to pass through the tube bundle multiple times according to the specified path, and enhancing the degree of fluid turbulence. The heat exchange tubes can be arranged in equilateral triangles or squares on the tube plate. The equilateral triangle arrangement is relatively compact, with a high degree of turbulence in the fluid outside the pipe and a large heat transfer coefficient; A square arrangement facilitates cleaning outside the pipe and is suitable for fluids that are prone to scaling.
