Work
The product is enclosed in the shell wall as the heat transfer tube bundle heat exchanger surface partitions. The heat exchanger structure is relatively simple, reliable operation, a variety of structural materials used (mainly metal) manufactured in high temperature, high pressure is used, is currently the most widely used type.

Structure
Mostly cylindrical shell, and loaded with bundles, bundle tube sheet at both ends fixed. For both hot and cold heat transfer fluid, a flow in the pipe, known as the tube side fluid; the other flow in the tube, known as the shell fluid. To improve the heat transfer tube coefficient of fluid, usually a number of baffles within the shell installed. Shell fluid damper can improve the speed, distance required to force fluid through multiple horizontal tube bundles, enhance the level of fluid turbulence. Tubes in the tube sheet may be arranged in an equilateral triangle or square. More compact arrangement of an equilateral triangle, tube high degree of fluid turbulence, heat transfer coefficient; square arrangement of the tube for easy cleaning, easy to scale for the fluid.
Each time the fluid through the tube bundle is called a monitor; each time through the shell as a shell. Icons for the most simple one-way single-tube shell heat exchanger, referred to as the 1-1 heat exchanger. To improve pipe flow velocity, can be set in both ends of the tube inside the partition, the entire tube were divided into several groups. This part of the tube through the fluid at a time, so many times in the custody of a round-trip, this is called multi-tube process. Similarly, to improve the flow tube can also be installed in vertical baffles in the shell, forcing the fluid through the shell space many times, as many shell. Multiple-way and multi-shell works with applications.

FEATURES
1. In many medium with excellent corrosion resistance, and therefore can be relatively thin wall and improve the heat transfer effect;
2. Since the invasion of liquid titanium is small, so the way the surface of the condensation dropwise condensation. This means that condensation heat transfer surface continuously updated, greatly increase the heat transfer coefficient;
3. smooth surface, Paradise layer of dirt factor greatly reduced;
4. density, high strength, small size and weight equipment;
5. I produced and tube heat exchanger and material contact parts are corrosion resistant (titanium, nickel, etc.) material, effectively improve the life of the equipment and overall performance.
