In the figure: 1. a tube sheet substrate; 2. a heat exchange tube base tube; 3. lining a titanium pipe; 4. a tube sheet composite material; 5. welding a first welding point; 6. a titanium cover plate; 7. welding spots II; 8. and a third welding spot.
Detailed Description
The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.
As shown in fig. 1, the utility model provides an air cooler is with compound lining titanium pipe, including tube sheet substrate 1, run through the heat exchange tube parent tube 2 that has fixed connection on the tube sheet substrate 1, the inboard of heat exchange tube parent tube 2 is equipped with lining titanium pipe 3, and outside the one end that lining titanium pipe 3 is close to tube sheet substrate 1 was located heat exchange tube parent tube 2, the one pot head that lining titanium pipe 3 is located heat exchange tube parent tube 2 outside was equipped with fixed connection and the titanium apron 6 that contacts with tube sheet substrate 1.
As shown in fig. 1, a tube sheet composite material 4 is arranged on one side of the tube sheet base material 1 close to the titanium cover plate 6, an opening is formed in the tube sheet composite material 4, and the titanium cover plate 6 is located in the opening. The tube plate composite material 4 can protect the tube plate base material 1, so that the situation that one surface of the tube plate base material 1, which is in contact with the tube plate composite material 4, is corroded after being contacted with a heat exchange medium is avoided, and the tube plate composite material 4 is damaged after being used for a long time, and is convenient for workers to overhaul or replace.
As shown in fig. 1, a welding point one 5 for fixing the tube sheet substrate 1 and the heat exchange tube substrate tube 2 together is arranged between the tube sheet substrate 1 and the heat exchange tube substrate tube 2. Welding spot 5 is located the one side that the tube sheet substrate 1 is close to tube sheet compound material 4, can fix tube sheet substrate 1 and heat exchange tube parent tube 2 welding together through welding spot 5, increases the fastness that tube sheet substrate 1 and heat exchange tube parent tube 2 are connected.
As shown in fig. 1, a second welding point 7 for fixing the titanium cover plate 6 and the titanium lining tube 3 together is arranged between one side of the titanium cover plate 6, which is far away from the tube plate base material 1, and the titanium lining tube 3. After the titanium cover plate 6 and the titanium lining pipe 3 are welded together through the second welding spot 7, the titanium cover plate 6 can be fixed, and the stability of the titanium lining pipe 3 can be improved.
As shown in fig. 1, the tube plate substrate 1 and the heat exchange tube base tube 2 are both made of carbon steel; the tube plate composite material 4 is made of titanium. The tube plate base material 1 and the heat exchange tube base tube 2 are made of carbon steel or low alloy steel to reduce the use of titanium and the manufacturing cost, and the tube plate composite material 4 is made of titanium to improve the corrosion resistance of the tube plate base material 1.
As shown in fig. 1, a third welding point 8 for fixing the tube sheet composite material 4 and the tube sheet base material 1 together is provided between the tube sheet composite material 4 and the tube sheet base material 1. Through the setting of solder joint three 8 to 4 welded fastening of composite material of tube sheet are on tube sheet substrate 1, and can make solder joint three 8 keep away from the position of tube sheet substrate 1 and be the bulge form, so that push down the one side that deviates from tube sheet substrate 1 with titanium apron 6, further increase the steadiness of titanium apron 6.
When the heat exchange tube base tube is used, the titanium lining tube 3 and the heat exchange tube base tube 2 generate friction shrinkage of the inner tube and the outer tube through an internal pressure or external pressure die, part of mechanical energy is converted into heat energy, the inner tube reaches a first softening point, or the outer tube is shrunk, the inner tube and the outer tube are in interference fit and are tightly attached, and the operation of fixing the titanium lining tube 3 in the heat exchange tube base tube 2 is realized; the heat exchange tube base tube 2 is arranged on the tube plate base material 1, the heat exchange medium can flow in the titanium lining tube 3 and cannot contact with the heat exchange tube base tube 2, the heat exchange tube base tube 2 cannot be corroded, the titanium cover plate 6 can block one end, close to the tube plate base material 1, of the heat exchange tube base tube 2, the heat exchange tube base tube 2 is further prevented from contacting with the heat exchange medium, and the service life of the heat exchange tube base tube 2 is prolonged; meanwhile, the base pipe 2 of the heat exchange tube wraps most of the titanium lining pipe 3 to protect the titanium lining pipe 3, and the base pipe 2 of the heat exchange tube and the titanium lining pipe 3 are matched with each other, so that the service lives of the base pipe 2 and the titanium lining pipe 3 are prolonged, and the production and manufacturing costs are reduced; after installing tube sheet substrate 1 in the air cooler, when the air cooler in the use, the heat transfer medium then flows in lining titanium pipe 3, can not contact with heat exchange tube parent tube 2, has avoided heat exchange tube parent tube 2 to receive the corruption.
