  In general, tube heat exchanger in hot water unit has long life span.   Shell and tube heat exchanger structure: The shell and tube heat exchanger is composed of shell, heat transfer tube bundle, tube sheet, baffle plate (baffle plate), and tube box. The shell is mostly cylindrical with a tube bundle inside, and both ends of the tube bundle are fixed on the tube plate. There are two types of heat transfer: hot fluid and cold fluid, one is the fluid inside the tube, called the tube side fluid; the other is the fluid outside the tube, called the shell side fluid. In order to improve the heat transfer coefficient of the fluid outside the tube, a number of baffles are usually arranged in the tube shell. The baffle can increase the velocity of the fluid in the shell side, make the fluid pass through the tube bundle multiple times at a specified distance, and improve the turbulence of the fluid. The heat exchange tubes can be arranged in an equilateral triangle or square on the tu...
