Titanium alloy heat exchangers are widely used in production. Different types of titanium alloy heat exchangers are used in different production environments. So, what are the types of titanium heat exchangers, Let's explore them together.
Here is the content list:
The fixed tube and plate titanium alloy heat exchangers
The floating head titanium alloy heat exchanger
The U-tube titanium alloy heat exchanger
Titanium alloy fixed tube plate heat exchanger is the most typical inter-wall heat exchanger, it has a long history of industrial applications, and still occupies a dominant position in all heat exchangers. Tube heat exchanger is mainly composed of shell, tube bundle, tube plate, and head, etc. The shell is mostly circular, with parallel tube bundles inside, and the tube bundles are fixed to the tube plate at both ends. It is the two ends of the tube plate directly welded together with the shell. A tube bundle is arranged in the shell, the two ends of the tube bundle are fixed on the tube sheet by welding, expansion, or expansion welding, and the periphery outside the tube sheet is fastened with the head flange by bolts. Fixed tube plate heat exchanger structure is simple, inexpensive, and easy to manufacture, easy to clean and repair the tube process, but the shell process is difficult to be clean, the tube bundle is manufactured after the existence of temperature stress. When the heat exchanger tube and shell have a large temperature difference, the shell should also be equipped with expansion joints.
The tube sheet at one end of the titanium alloy floating head heat exchanger is fixed between the shell and the tube box, and the tube sheet at the other end can move freely in the shell, that is, the thermal expansion of the shell and tube bundle can be free. Therefore, there is no temperature difference stress between the tube bundle and the shell. Generally, the floating head is detachable, and the tube bundle can be pulled out and installed freely. This structure of floating head heat exchanger can be used under the condition of a large temperature difference between tube bundle and shell. The cleaning and maintenance of tube bundle and shell are more convenient, but its structure is relatively complex and has high requirements for sealing.
The U-shaped tubular heat exchanger is to form the heat exchange tube into a U-shape, and both ends are fixed on the same tube sheet. Since the shell is separated from the heat exchange tube, the heat exchange tube bundle can expand freely without temperature difference stress due to the temperature difference of the medium. The U-tube heat exchanger has only one tube sheet and no floating head, so its structure is relatively simple. The tube bundle can be pulled out and installed freely, which is convenient for cleaning. It has the advantages of a floating head heat exchanger. However, because the heat exchange tube is made into U-shaped bends with different radii, the outermost heat exchange tube can be replaced after being damaged, and other tubes can only be blocked if damaged. At the same time, compared with the fixed tube sheet heat exchanger, because the heat exchange tube is limited by the bending radius, there is a gap in the center of its tube bundle, and the fluid is easy to short circuit, which affects the heat transfer effect.
