Abstract
The utility model discloses a kind of novel heat exchange tube sheet, the heat exchange tube sheet is provided with tubesheet holes, the diameter of the tubesheet holes is identical with heat exchange bore, heat exchange tube sheet is provided with downward annular boss, the boss axis is collinear with tube sheet axially bored line, and the internal diameter of boss is identical with tube sheet bore dia, boss is faced upwards along following table and is provided with the cylinder shape groove matched with heat exchanger tube external diameter, and the recess axis are collinear with boss axis.This novel heat exchange tube sheet is fixed by butt welding with heat exchanger tube, is solved the problems, such as there is shell side dead angle between traditional heat exchange tube sheet and heat exchanger tube, has been prevented the generation of buildup, improve the quality that heat changes container.
Description
Technical field
This utility model is related to a kind of heat exchange container of photovoltaic industry, more particularly to a kind of novel heat exchange tube sheet.
Background technology
Existing heat exchange container, its heat exchanger tube 1 are mostly inserted into, in the tubesheet holes of heat exchange tube sheet 2 (as shown in Figure 1), changing
There is gap between heat pipe 1 and heat exchange tube sheet 2, need to be welded by standard, welding position is tube sheet angle welding, i.e. tube side side
Weld seam 3, the shell side side weldering as the cross-linking structure by heat exchanger tube 1 with heat exchange tube sheet 2 is limited, inside heat exchange tube sheet 2
Seam 4 cannot really be welded, and can form dead angle herein.Generally under state, it is material in tube side, is heat exchange medium in shell side, so
If shell side dead angle do not affect actual product.But as fruit product medium needs to circulate in shell side, this dead angle can then produce
Buildup, affects the quality of heat exchange container, it is therefore desirable to improve.
Utility model content
For above-mentioned technological deficiency, this utility model provides a kind of novel heat exchange tube sheet, and the heat exchange tube sheet can be with heat exchanger tube
Butt welding is fixed, and is solved the problems, such as there is shell side dead angle between traditional heat exchange tube sheet and heat exchanger tube, has been prevented buildup
Produce, improve the quality that heat changes container.
In order to reach above-mentioned technique effect, the technical solution adopted in the utility model is：
A kind of novel heat exchange tube sheet, the heat exchange tube sheet are provided with tubesheet holes, the diameter of the tubesheet holes and heat exchange bore
Identical, heat exchange tube sheet is provided with downward annular boss, and the boss axis is collinear with tube sheet axially bored line, and the internal diameter and pipe of boss
Plate hole diameter is identical, and boss is faced upwards along following table and is provided with the cylinder shape groove matched with heat exchanger tube external diameter, the recess axis
Collinear with boss axis.
Further, the depth of groove is 0.5mm.
Further, the minimum range between the outside the boss wall and groove inner wall is 0.3 ± 0.03mm.
Compared with prior art, the beneficial effects of the utility model are：By using tube sheet bore dia and heat exchanger tube external diameter
Identical heat changes tube sheet, arranges boss and groove on heat exchange tube sheet, so as to this utility model can be fixed with heat exchanger tube butt welding,
Solve the problems, such as there is shell side dead angle between traditional heat exchange tube sheet and heat exchanger tube, prevented the generation of buildup, improve heat
Change quality and the safety of container.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of description, and in order to allow above and other purpose of the present utility model, feature
Can become apparent with advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, described in detail.
Description of the drawings
Fig. 1 is exchange heat in prior art tube sheet and the welding structure schematic diagram of heat exchanger tube.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the welding structure schematic diagram of this utility model and heat exchanger tube.
Each label and corresponding entitled in figure：
1. heat exchanger tube, 2. exchange heat tube sheet, 3. tube side side weld, 4. shell side side weld, 11. heat exchanger tubes, 12. heat exchange tube sheets,
13. boss, 14. grooves, 15. tubesheet holes.
Specific embodiment
As shown in Figures 2 and 3, a kind of novel heat exchange tube sheet, the heat exchange tube sheet 11 are provided with tubesheet holes 15.The tubesheet holes
15 diameter is identical with 11 internal diameter of heat exchanger tube, and heat exchange tube sheet 12 is provided with downward annular boss 13.13 axis of the boss and pipe
15 axis of plate hole is collinear, and the internal diameter of boss 13 is identical with 15 diameter of tubesheet holes, and boss 13 is faced upwards along following table and is provided with and heat exchange
The cylinder shape groove 14 that 11 external diameter of pipe matches.14 axis of the groove is collinear with 13 axis of boss.Preferably, the groove
14 depth are 0.5mm, and the minimum range between 14 inwall of 13 lateral wall of boss and groove is 0.3 ± 0.03mm.
As shown in figure 3, first dock heat exchanger tube 11 during this utility model use, will heat exchanger tube 11 be inserted in groove 14,
Then using deep hole welding machine, welded from inside, make inside and outside all melt, inside and outside all without dead angle presence so as to reach,
Prevent the generation that heat exchange container causes buildup in use, improve the quality that heat changes container.
This utility model is not limited to above-mentioned specific embodiment, for the person of ordinary skill of the art from upper
State design to set out, without performing creative labour, done a variety of conversion, all fall within protection domain of the present utility model it
Interior.
