    Dry Type High Pressure Shell And Tube Heat Exchanger For Rooftop HVAC Units

    U - Shaped Dry Type


    Tube Heat Exchanger for Rooftop HVAC Units


    Dry Type High Pressure Shell And Tube Heat Exchanger For Rooftop HVAC Units from the shell, heat


    pipe bundle, tube plate, baffle (baffle) and the composition of the box and other components. The shell is


    mostly cylindrical, with tube bundles inside, tube ends fixed on the tube plate. Heat and heat of the two


    kinds of fluid, one in the tube flow, known as the pipeline fluid; another flow outside the tube, known as the


    shell process fluid. In order to improve the heat transfer coefficient of the fluid outside the tube, a number


    of baffles are usually installed in the housing. The baffle can increase the shell-side fluid velocity, forcing


    the fluid to pass through the tube bundle several times according to the specified path, and enhance the


    turbulence of the fluid. The heat transfer tubes may be arranged in equilateral triangles or squares on the


    tubesheet. The equilateral triangular arrangement is more compact, the turbulence of the tube is high,


    and the heat transfer coefficient is large. The square arrangement is convenient for cleaning outside the


    tube and is suitable for the fluid which is easy to scale.


    The fluid is once referred to as a pipe by pipe bundle once; every time the shell is once referred to as a


    shell side. Illustrated as the simplest single-shell single-tube heat exchanger, referred to as 1-1 heat


    exchanger. In order to improve the fluid velocity in the pipe, a partition plate can be provided at both ends


    of the pipe box, and all the pipes are divided into several groups. So that each time the fluid only through


    the part of the tube, and thus in the tube bundle back and forth many times, which is called multi-tube.


    Similarly, in order to improve the flow rate outside the tube can also be installed in the shell longitudinal


    baffle, forcing the fluid through the shell space several times, known as the multi-shell process. Multi-tube


    and multi-shell can be used in conjunction with the application.
