Abstract
This utility model discloses the heat collecting sheet of a kind of gas and hot water metal v-belt elliptical aperture structure, including: heat collecting sheet body, the heat-transfer pipe installing hole being arranged on heat collecting sheet body, and it is positioned at the slotted eye around heat-transfer pipe installing hole；It is characterized in that, the major axis of described elliptical aperture is vertical with flow of flue gas direction.Owing to the major axis of elliptical aperture is vertical with flow of flue gas direction, flue gas flows through the vortex that elliptical hole formed can wash away fin surface and pipe outer wall well, the flow boundary layer of flue gas can be destroyed more consumingly, the ability making flowing momentum and energy transmission strengthens, and improves the heat exchange property of heat-exchange system.Meanwhile, this structure fabrication processes is simple, it is easy to accomplish, save material, compared with tradition circular hole fin, not only reduce the flow resistance of high-temperature flue gas side, heat exchange property is significantly enhanced, and commercial production is not likely to produce burr, improve production stability.
Description
Technical field
This utility model relates to gas heater parts, particularly relates to a kind of gas and hot water metal v-belt elliptical aperture structure
Heat collecting sheet.
Background technology
For improving the heat exchange efficiency between flue gas and fin, on gas heater heat collecting sheet general use circular flanging bore or
Pressure bridge architecture, its objective is the flow boundary layer by destruction high-temperature flue gas and connects flue gas between Neighbor Set backing, thus carrying
The heat exchange property of high heat-exchange system.See described in the Chinese utility model patent that notification number is CN204154169U.But
These turbulence structures existing are to improving heat transfer effect inconspicuous, and in commercial production, circular flanging bore or pressure bridge architecture hold
The burr produced because of die wear easily occurs, thus affects its stability further.
Summary of the invention
For problems of the prior art, the purpose of this utility model is to provide that a kind of production stability is good, has
Effect reduces the flow resistance of high-temperature flue gas side, the heat collecting sheet of heat exchange property is greatly improved.
For reaching object above, this utility model adopts the following technical scheme that.
A kind of heat collecting sheet of gas and hot water metal v-belt elliptical aperture structure, including: heat collecting sheet body, it is arranged on heat collecting sheet body
On heat-transfer pipe installing hole, and be positioned at the slotted eye around heat-transfer pipe installing hole；It is characterized in that, the length of described elliptical aperture
Axle is vertical with flow of flue gas direction.
As with improvement, described heat-transfer pipe installing hole is at least two rows, and every package includes at least two heat-transfer pipe installing hole；Institute
State elliptical aperture to be arranged between adjacent two row's heat-transfer pipe installing holes.
As with improvement, between the adjacent two heat-transfer pipe installing holes often arranged, it is provided with at least one elliptical aperture.
As with improvement, the quantity of described heat-transfer pipe installing hole is five and is divided into two rows, under upper row two arrange three in
Staggered, all arrange an elliptical aperture about the top of lower row each heat-transfer pipe installing hole, two heat-transfer pipes of upper row are installed
Between hole, both sides be also respectively arranged an elliptical aperture.
As with improvement, offer U-type groove on the base of heat collecting sheet body.
As with improvement, described U-type groove is between adjacent two heat-transfer pipe installing holes.
Compared with prior art, the beneficial effects of the utility model are:
One, vertical with flow of flue gas direction due to the major axis of elliptical aperture, flue gas flows through the vortex energy that elliptical hole is formed
Wash away fin surface and pipe outer wall well, the flow boundary layer of flue gas can be destroyed more consumingly, make flowing momentum and energy
The ability of transmission strengthens, and improves the heat exchange property of heat-exchange system.
Two, this structure fabrication processes is simple, it is easy to accomplish, save material, compared with tradition circular hole fin, not only reduce
The flow resistance of high-temperature flue gas side, heat exchange property are significantly enhanced, and are not likely to produce burr in commercial production, improve raw
Produce stability.
Accompanying drawing explanation
Fig. 1 show the heat collecting sheet structural representation that this utility model provides.
Description of reference numerals:
1: heat collecting sheet body, 2: heat-transfer pipe installing hole, 3: slotted eye, 4:U type groove.
Detailed description of the invention
It is more fully understood that essence of the present utility model for convenience of those skilled in the art, new to this practicality below in conjunction with the accompanying drawings
The detailed description of the invention of type is described in detail.
As it is shown in figure 1, the heat collecting sheet of a kind of gas and hot water metal v-belt elliptical aperture structure, including: heat collecting sheet body 1, arrange
Heat-transfer pipe installing hole 2 on heat collecting sheet body 1, and the slotted eye 3 being positioned at around heat-transfer pipe installing hole 2；Its feature exists
In, the major axis of described elliptical aperture 3 is vertical with flow of flue gas direction (as shown by arrows in FIG.).
Wherein, described heat-transfer pipe installing hole 2 at least two rows, every package includes at least two heat-transfer pipe installing hole；Described ellipse
Circular hole 3 is arranged between adjacent two row's heat-transfer pipe installing holes, and between the adjacent two heat-transfer pipe installing holes often arranged.
In the present embodiment, the quantity of preferred tube installing hole 2 is five and is divided into two rows, under upper row two arrange three in
Staggered, all arrange an elliptical aperture 3 about the top of lower row each heat-transfer pipe installing hole, two heat-transfer pipes of upper row are installed
Between hole, both sides be also respectively arranged an elliptical aperture, i.e. altogether arrange nine elliptical apertures.
Further, offering U-type groove 4 on the base of heat collecting sheet body 1, described U-type groove 4 is positioned at adjacent two heat-transfer pipe peaces
Between dress hole 2, it is used for improving the exchange efficiency of 1 flue gas of Neighbor Set sink body, thus improves the heat-exchange performance of heat-exchange system
Energy.
Essence of the present utility model has been described in detail by above detailed description of the invention, but can not come this reality with this
Limit with novel protection domain.It should be evident that under the enlightenment of this utility model essence, the common skill of the art
Art personnel also can carry out many improvement and modification, it should be noted that these improve and modify all to fall in power of the present utility model
Within the scope of profit is claimed.
