Abstract
The utility model relates to an air cooler tube head structure, specific air cooler anticorrosion tube head structure that says so belongs to air cooler tube head technical field. It includes tube sheet, heat exchange tube and aluminium fin parent tube, is equipped with a tubesheet holes and the 2nd tubesheet holes in the tube sheet. Heat exchange tube middle part surface is equipped with aluminium fin parent tube, and the front portion of heat exchange tube is passed in the 2nd tubesheet holes stretches into a tubesheet holes, and aluminium fin parent tube front portion is stretched into in the 2nd tubesheet holes. Heat exchange tube and aluminium fin parent tube lie in the protruding structure that the 2nd tubesheet holes internal surface was equipped with outside salient for the interior side surface of the 2nd tubesheet holes is hugged closely to heat exchange tube and aluminium fin parent tube. The utility model discloses rise by technology through subsides and does not have the clearance in the outside of tube sheet and aluminium fin parent tube junction, and the heat exchange tube surrounds by the aluminum pipe completely, has avoided the outside of tubes corruption.
Description
Technical field
The utility model relates to a kind of air cooler header structures, and a kind of air cooler corrosionproof pipes header structure, belongs to air cooler tube head technical field specifically.
Background technology
In prior art, Air-cooled Heat Exchanger increases the heat transfer area of heat exchanger tube by the outer aluminum fin of heat exchanger tube.In use, because the back side of tube-to-tube sheet connection is chronically exposed in air by the restriction of rolled finned tube, bears the corrosion of acid steam, easily lost efficacy.In traditional design process, as shown in Figure 1, adopt at tube sheet 1 back face chamfer, allow the root of aluminum fin-stock base tube 3 stretch in the chamfering of tube sheet 1.But be subject to the impact of aluminum fin-stock base tube 3 root depth and chamfer height, can not ensure that finned tube base tube part does not expose in atmosphere completely.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus provides a kind of air cooler corrosionproof pipes header structure, heat exchanger tube can be coated in tube sheet completely, reduces the corrosion of air exchange heat pipe.
According to the technical scheme that the utility model provides, air cooler corrosionproof pipes header structure comprises tube sheet, heat exchanger tube and aluminum fin-stock base tube, it is characterized in that: be provided with the first tubesheet holes and the second tubesheet holes in tube sheet, and the diameter of the second tubesheet holes is greater than the diameter of the first tubesheet holes; Heat exchanger tube center outer surface is provided with aluminum fin-stock base tube, and the front portion of heat exchanger tube is stretched in the first tubesheet holes through the second tubesheet holes, and aluminum fin-stock base tube front portion is stretched in the second tubesheet holes; Described heat exchanger tube and aluminum fin-stock base tube are positioned at the second tubesheet holes inner surface and are provided with bulge-structure outwardly, make heat exchanger tube and aluminum fin-stock base tube be close to the second tubesheet holes inner surface.
Further, form straight locating platform between the first tubesheet holes and the second tubesheet holes, aluminum fin-stock base tube front end realizes location by locating platform.
Compared with the prior art the utility model has the following advantages:
The utility model structure is simple, compact, reasonable, first tubesheet holes and the second tubesheet holes are set in tube sheet, make the root of aluminum fin-stock base tube stretch into tube sheet completely, and then carry out subsides expansion process formation bulge-structure, heat exchanger tube, aluminum fin-stock base tube root and tube sheet are fitted tightly completely; There is not gap by pasting expansion process in the outside of tube sheet and aluminum fin-stock base tube junction, and heat exchanger tube is surrounded by aluminum pipe completely, avoids the outer corrosion of pipe.

Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Figure 2, the utility model mainly comprises tube sheet 1, heat exchanger tube 2 and aluminum fin-stock base tube 3, and the diameter being provided with the first tubesheet holes 4 and the second tubesheet holes 5, second tubesheet holes 5 in tube sheet 1 is greater than the diameter of the first tubesheet holes 4.
Heat exchanger tube 2 center outer surface is provided with aluminum fin-stock base tube 3, and the front portion of heat exchanger tube 2 is stretched in the first tubesheet holes 4 through the second tubesheet holes 5, and aluminum fin-stock base tube 3 front portion is stretched in the second tubesheet holes 5.Described heat exchanger tube 2 and aluminum fin-stock base tube 3 are positioned at the second tubesheet holes 5 inner surface and are provided with bulge-structure 6 outwardly, make heat exchanger tube 2 and aluminum fin-stock base tube 3 be close to the second tubesheet holes 5 inner surface.
Described bulge-structure 6 obtains by pasting expansion process, aluminum fin-stock base tube 3 front end root is covered by the second tubesheet holes 5 completely, heat exchanger tube 2 is not exposed in atmosphere, improves the decay resistance of heat exchanger tube 2.
Form straight locating platform 7 between described first tubesheet holes 4 and the second tubesheet holes 5, aluminum fin-stock base tube 3 front end realizes location by locating platform 7.
The utility model arranges the first tubesheet holes 4 and the second tubesheet holes 5 in tube sheet, makes the root of aluminum fin-stock base tube stretch into tube sheet completely, and then carries out subsides expansion process formation bulge-structure, and heat exchanger tube, aluminum fin-stock base tube root and tube sheet are fitted tightly completely.There is not gap by pasting expansion process in the outside of tube sheet and aluminum fin-stock base tube junction, and heat exchanger tube is surrounded by aluminum pipe completely, avoids the outer corrosion of pipe.
