Abstract
The utility model discloses the connection structures of a kind of heat exchanger tube sheet and heat exchanger tube, and including tube sheet and heat exchanger tube, the tube sheet is equipped with multiple through-holes for being used to install heat exchanger tube, and multiple through-hole is spaced and circumferentially formula is evenly distributed with；The end of the heat exchanger tube is draw section, which is inserted into above-mentioned through-hole and stretches out tube sheet, stretch out the part of tube sheet in the draw section and the joint of tube sheet is welded with circular weld.The connection structure of a kind of heat exchanger tube sheet of the utility model and heat exchanger tube, it is rational in infrastructure, welding difficulty is reduced, and do not influence the heat transfer effect of heat exchanger.
Description
Technical field
The utility model is related to the connection structures of a kind of heat exchanger tube sheet and heat exchanger tube.
Background technology
Heat exchanger is widely used in the industrial circles such as petrochemical industry, electric power, environmental protection.Heat exchanger is a kind of the two of different temperatures
Kind or two or more fluids between realize the energy-saving equipment of heat transfer between material, be that heat is made to be transmitted by the higher fluid of temperature
It gives temperature relatively low fluid, fluid temperature (F.T.) is made to reach the index of flow specification, to meet the needs of process conditions, while be also to carry
One of capital equipment of high energy source utilization rate.In the production process of heat exchanger, need multiple heat exchanger tubes being connected to heat exchanger
On tube sheet, the mode of generally use welding realizes the connections of exchanger tubes and tubesheets, but by multiple compact arranged heat exchanger tubes
When being welded on heat exchanger tube sheet, since the spacing between adjacent heat exchange tubes is smaller, welding difficulty is caused to increase, and influence welding
Quality.
Utility model content
It is rational in infrastructure the purpose of this utility model is to provide the connection structure of a kind of heat exchanger tube sheet and heat exchanger tube,
Welding difficulty is reduced, and does not influence the heat transfer effect of heat exchanger.
To achieve the above object, the technical solution of the utility model is the connection of a kind of heat exchanger tube sheet of design and heat exchanger tube
Structure, including tube sheet and heat exchanger tube, the tube sheet is equipped with multiple through-holes for being used to install heat exchanger tube, and multiple through-hole is mutual
Every and circumferentially formula is evenly distributed with；The end of the heat exchanger tube is draw section, which is inserted into above-mentioned through-hole and stretches out tube sheet, described
The part of tube sheet is stretched out in draw section and the joint of tube sheet is welded with circular weld.In said program, the tube sheet of heat exchanger
On need to weld the uniformly distributed heat exchanger tube of multiple circumferentially formulas, should be kept to ensure the heat transfer effect of heat exchanger, between adjacent heat exchange tubes
Smaller spacing, therefore cause the space of welding smaller, the difficulty of welding is increased, and be difficult to ensure that welding quality；Then, it will change
The end of heat pipe processes to form draw section by the draw, thus makes the spacing increase of welding portion between adjacent heat exchange tubes, and
Do not change the spacing of heat exchanging part, reduce welding difficulty, and do not influence the heat transfer effect of heat exchanger.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and the protection model of the utility model cannot be limited with this
It encloses.
The utility model specific implementation technical solution be：
As shown in Figure 1, the connection structure of a kind of heat exchanger tube sheet and heat exchanger tube, including tube sheet 1 and heat exchanger tube 2, the pipe
Plate 1 is equipped with multiple through-holes for being used to install heat exchanger tube 2, and multiple through-hole is spaced and circumferentially formula is evenly distributed with；The heat exchange
The end of pipe 2 is draw section 3, which is inserted into above-mentioned through-hole and stretches out tube sheet 1, stretches out tube sheet 1 in the draw section 3
Part and the joint of tube sheet 1 are welded with circular weld 4.In said program, need to weld on the tube sheet 1 of heat exchanger multiple in circle
To ensure the heat transfer effect of heat exchanger, smaller spacing should be kept, therefore lead between adjacent heat exchange tubes 2 for the uniformly distributed heat exchanger tube 2 of all formulas
The space for causing welding is smaller, increases the difficulty of welding, and be difficult to ensure that welding quality；Then, the end of heat exchanger tube 2 is passed through
The draw is processed to form draw section 3, thus makes the spacing increase of welding portion between adjacent heat exchange tubes 2, and does not change heat exchanging part
The spacing divided, reduces welding difficulty, and do not influence the heat transfer effect of heat exchanger.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, under the premise of the utility model technical principle is not departed from, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
Claims (1)
