Background

The double-pipe heat exchanger mainly comprises a shell (comprising an inner shell and an outer shell), a U-shaped elbow pipe, a stuffing box and the like. The required pipes can be made of common carbon steel, cast iron, copper, titanium, ceramic glass and the like respectively. The tube is typically secured to a support. Two different media can flow in the tube in opposite directions (or in the same direction) to achieve the purpose of heat exchange. In the process of reverse heat exchange, hot fluid enters from the upper part, cold fluid enters from the lower part, and heat is transferred from one fluid to the other fluid through the wall of the inner pipe. The distance that the hot fluid flows from the inlet end to the outlet end is called a tube pass; a heat exchanger in which fluid is introduced through a connection pipe of the shell and introduced from one end to the other end of the shell and which transfers heat in this manner is called a shell-side double pipe heat exchanger.
