Abstract
The utility model relates to a heat exchanger with a stick expansion device, comprising a heat exchanging tube and a tube sheet, wherein the tube sheet is provided with a tube hole, the heat exchanging tube is inserted in the tube hole in the tube sheet, and is internally provided with a tube expanding machine which installs the heat exchanging tube on the inner wall of the tube hole in the tube sheet in a stick expansion manner. In the utility model, the tube exchanging machine is adopted for installing the heat exchanging tube on the inner surface of the tube hole in the tube sheet in a stick expansion manner, thus eliminating the clearance between the heat exchanging tube and the tube hole, and simultaneously, the head of the heat exchanging tube is welded with the port of the tube sheet, thus guaranteeing the connection strength and achieving the purpose of eliminating the clearance corrosion and preventing the vibration of the tube bundle.
Description
Technical field
The utility model relates to a kind of heat exchanger, especially a kind of heat exchanger with the bloated device of subsides.
Background technology
Heat exchanger is with the equipment of the part heat transferred cold fluid of hot fluid, claims heat exchanger again.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies critical role aborning.At present, the heat exchange effect of the heat exchanger on the market is not fine, and main cause is that the intensity of fixed-site of heat exchanger tube is not high, cause tube bundle vibration easily, and there is the gap between heat exchanger tube and the fixed position, causes crevice corrosion easily like this, thereby influence the heat exchange effect.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of and can eliminate crevice corrosion, and can prevent the heat exchanger that pastes bloated device that has of tube bundle vibration.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of heat exchanger with the bloated device of subsides, comprise heat exchanger tube and tube sheet, described tube sheet is provided with pore, described heat exchanger tube inserts in the pore of tube sheet, is provided with in the heat exchanger tube heat exchanger tube is posted at tube expander on the tube sheet pore inwall.
Further,, prevent tube bundle vibration, the tube head of heat exchanger tube described in the utility model and the welding of the port of tube sheet in order to increase the bonding strength of heat exchanger tube and tube sheet.
Again further, in order to strengthen the heat exchange effect, the pore circumference on the tube sheet described in the utility model is evenly distributed on the tube sheet, and the quantity of pore is at least two, all is inserted with heat exchanger tube in each pore.
The beneficial effects of the utility model are, solved the defective that exists in the background technology, adopt tube expander that heat exchanger tube is posted on the tube sheet pore inner surface, eliminated heat exchanger tube and pore gap between the two, simultaneously with heat exchanger tube tube head and the welding of tube sheet port, can guarantee bonding strength, reach the purpose of eliminating crevice corrosion and preventing tube bundle vibration simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1 R part;
Among the figure: 1, heat exchanger tube; 2, tube sheet; 21, pore; 3, tube expander.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of heat exchanger as shown in Figure 1, 2 with the bloated device of subsides, comprise heat exchanger tube 1 and tube sheet 2, described tube sheet 2 is provided with pore 21, and described heat exchanger tube 1 inserts in the pore 21 of tube sheet 2, is provided with in the heat exchanger tube 1 heat exchanger tube 1 is posted at tube expander 3 on tube sheet pore 21 inwalls.In order to increase the bonding strength of heat exchanger tube 1 and tube sheet 2, prevent tube bundle vibration, the port welding of the tube head of described heat exchanger tube 1 and tube sheet 2.
Specifically, in order to strengthen the heat exchange effect, the utility model circumference on tube sheet 2 is evenly distributed with at least two pore 21, and heat exchanger tube 1 is inserted in the corresponding pore 21.
What describe in the above specification is the specific embodiment of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, the person of an ordinary skill in the technical field after having read specification can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from the essence and the scope of utility model.
