Characteristics of titanium tube heat exchanger

The heat exchanger is an indispensable device for heat exchange and transfer in the chemical production process. There are often some corrosive and oxidizing materials in the heat exchange, and the materials for manufacturing spiral plate heat exchangers are required to have strong corrosion resistance.

Finned titanium tube heat exchanger is also called tube fin heat exchanger. Its structural feature is that there are many fins on the outer or inner surface of the heat exchanger tube. Commonly used fins are longitudinal and horizontal. Titanium finned tube heat exchangers are used as air coolers and are widely used in industry. wide. The use of air instead of water cooling can not only be used in water-scarce areas, but also in places where there is sufficient water source, the use of air cooling has also achieved greater economic benefits. Of course, the addition of fins will increase the equipment cost, but generally when the ratio of the convective heat transfer coefficient of the two fluids exceeds 3:1, it is economically reasonable to use finned titanium tube heat exchangers. The connection between the fins and the tube surface should be tight, otherwise the contact thermal resistance at the connection is very large, affecting the heat transfer effect. Commonly used connection methods include hot sleeve, inlay, tension winding and welding. In addition, the finned tube can also be manufactured by integral rolling, integral casting, or machining. Gas heating and cooling problems are often encountered in chemical production. Because the convective heat transfer coefficient of the gas is very small, when another fluid that exchanges heat with the gas is water vapor condensation or cooling water, the gas side thermal resistance becomes the heat transfer control factor. To strengthen heat transfer at this time, it is necessary to increase the convective heat transfer area on the gas side. Fins are provided on the gas side of the heat exchange tube, which not only increases the heat transfer area on the gas side, but also enhances the degree of gas turbulence, reduces the thermal resistance on the gas side, and thus increases the gas heat transfer coefficient.
