Shell and tube type heat exchanger is composed of a casing, heat transfer tubes, tube plate, baffle plate (plate) and the tube box and other components. Housing is mostly cylindrical, with internal tube bundle, the bundle are fixed on a tube plate. Two fluid heat transfer of heat and cold, a flow in the tube, called the fluid tube; another in outside of the pipe flow, known as the shell side fluid. In order to improve the heat transfer coefficient of fluid outside the pipe, usually in the baffle is arranged inside the shell number. The baffle can improve the fluid velocity of shell, forcing the fluid according to the prescribed distance repeatedly horizontally through the bundle, enhance the degree of fluid turbulence. Tube heat exchanger on the tube plate can be equilateral triangle or square array. Equilateral triangle arrangement is compact, high degree of fluid outside the pipe turbulence, heat transfer coefficient; the square array is outside the tube cleaning is convenient, suitable for the fluid easily scaling.
