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; the heat exchanger transferring heat in this way is called as shell side double pipe heat exchanger, because the double pipe heat exchanger is widely used in petrochemical industry, refrigeration and other industry departments, originally single heat transfer mode and heat transfer efficiency can not meet the actual work and production, at present, researchers at home and abroad put forward many improved schemes for the double pipe heat exchanger to prolong the service life of the double pipe heat exchanger and enhance the use efficiency,
