What Is Tube Bundle in Heat Exchanger?

The tube bundle heat exchanger is a typical heat exchange device for exchanging heat between two fluids with different temperatures. Through this device, one fluid can be cooled and the other fluid can be heated to meet their respective needs. The equipment is widely used in chemical, petroleum, pharmaceutical, energy and other industrial sectors, and is one of the indispensable important equipment in chemical production.

Tube bundle heat exchanger
Application fields: chemical industry, petroleum, energy and other industrial sectors
Function: to exchange heat between fluids with different temperatures

Heat exchanger is one of the most widely used unit equipment in chemical industry, petroleum, energy and other industries. According to statistics, in the modern chemical industry, the investment in heat exchangers accounts for about 30% of the total investment in equipment, and in oil refineries, it accounts for about 40% of all process equipment. Seawater desalination process devices are almost all composed of heat exchangers. . The survey of foreign heat exchanger markets shows that although the competitiveness of various plate heat exchangers is rising, shell and tube heat exchangers still occupy a dominant position of about 64%.

Working principle of tube bundle heat exchanger
The fluid channel formed in the heat exchange tube of the tube bundle heat exchanger is called the tube side, and the fluid channel formed outside the heat exchange tube is called the shell side. One kind of working fluid enters the heat transfer tube through the inlet connection pipe at the head end, and its process can realize one-tube, two-tube and four-tube structures according to the process requirements; the other kind of working fluid enters the shell through the inlet connection pipe at one end of the shell And evenly distributed outside the heat transfer tubes, its flow state can be set in different types and numbers of baffles in the tube bundle according to the process requirements. Two working fluids with different temperatures enter the heat exchanger, the relatively high temperature working fluid transfers heat to the relatively low temperature working fluid through the heat exchange tube wall, the relatively high temperature working fluid is cooled, and the relatively low temperature working fluid The substance is heated to complete the goal of the two-fluid heat exchange process.
