The shell is cylindrical, a tube bundle is arranged in the shell, and two ends of the tube bundle are fixed on the tube plate. Two fluids for heat exchange, namely cold and hot fluids, one fluid flows in a pipe and is called a pipe side fluid; the other type flows outside the tube, called shell-side fluid. To increase the heat transfer coefficient of the fluid outside the tube, baffles are typically mounted within the housing. The baffle can increase the speed of shell-side fluid, force the fluid to pass through the tube bundle for a plurality of times according to a specified path, and strengthen the turbulence degree of the fluid. The heat exchange tubes can be arranged on the tube plate in an equilateral triangle or square shape. The equilateral triangle is compacter, the turbulence degree of the fluid outside the tube is high, and the heat transfer coefficient is large; the square arrangement is convenient for cleaning the outside of the pipe, and is suitable for fluid easy to scale.
In order to improve the heat exchange efficiency of the traditional shell-and-tube heat exchanger, the existing technical means are to add baffle plates on the shell side, use inner and outer finned tubes and winding tubes, set interlayers to reduce heat dissipation, and the like, for example, a shell-and-tube heat exchanger with a serpentine heat exchange tube of CN103017574A is provided, and the heat exchange efficiency is improved by setting and increasing the heat exchange flow. However, the traditional shell-and-tube heat exchanger is not subjected to heat preservation treatment, a large amount of heat is dissipated through the shell in the heat exchange process, the heat exchange effect caused by large heat dissipation capacity is not ideal, and the heat exchange coefficient is low. Most of the existing technical means are aimed at the problem of low heat transfer coefficient, and only few technical means are aimed at the problem of large heat dissipation capacity of the shell, so that improvement is still needed.
