Description
The structure of the shell and tube heat exchanger is relatively simple, compact and cheap, but the outside of the tube cannot be cleaned mechanically. The tube bundle of this kind of heat exchanger is connected to the tube plate, and the tube plate is welded to both ends of the shell respectively, and a top cover is connected to it, and the top cover and the shell are equipped with fluid inlet and outlet pipes. A series of baffles perpendicular to the tube bundle are usually installed outside the tube. At the same time, the connection between the tube and the tube sheet and the shell is rigid, and the inside and outside of the tube are two fluids with different temperatures.
