Tubular heat exchanger is currently a widely used heat exchanger in chemical and alcohol production. It mainly consists of shell, tube plate, heat exchange tube, head, baffle, etc. The required materials can be made of ordinary carbon steel, purple copper, or stainless steel respectively. During heat exchange, a fluid enters from the connecting tube of the head, flows in the tube, and exits from the outlet tube at the other end of the head, which is called the tube side; Another type of fluid enters through the connecting pipe of the shell and flows out from another connecting pipe on the shell, which is called the shell side.

The working principle of a tubular heat exchanger mainly consists of components such as a head, shell, tube bundle, flange connection, etc. A working fluid enters the heat transfer tube through the inlet pipe at the head end, and the process can achieve a structure of one tube side, two tube side, and four tube side according to the process requirements; Another type of working fluid enters the shell through an inlet pipe at one end and is evenly distributed outside the heat transfer tube. Its flow state can be set with different types and quantities of baffle plates in the tube bundle according to process requirements. As a heat transfer element - heat exchange tube, brass tube, copper finned tube, and steel pipe can be used according to process requirements, thereby ensuring heat exchange of working fluids with different physical properties and temperatures in the heat exchanger, achieving the purpose of cooling or heating.

Good corrosion resistance, high temperature resistance, good thermal conductivity, light weight, small footprint, non-toxic, non scaling, easy installation and maintenance, wide application range, low price, simple and compact structure, low fluid resistance, can manufacture large equipment, but lower pressure and temperature resistance compared to block hole type, suitable for non strong impact and small vibration situations, and better for cooling and condenser. After special processing, it can also be used for general heating equipment.
