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, a kind of gas heater rustless steel heat collecting sheet, including: rustless steel heat collecting sheet body 1, it is arranged on
Heat-transfer pipe connecting hole 2 on rustless steel heat collecting sheet body 1；It is characterized in that, described heat-transfer pipe connecting hole 2 is elliptical aperture flange
Hole, each elliptical aperture flanging bore is M N array arrangement, M, N >=2.
Wherein, described elliptical aperture 2 is arranged in two row six row, and the gap location between adjacent heat-transfer pipe connecting hole 2 is provided with ellipse
Round shape flow-disturbing flanging bore 3, long axis direction and the direction, each column place of described ellipticity flow-disturbing flanging bore 3 are all changed with gas heater
The flow direction (as shown by the arrows in Figure 1) of heat smoke is parallel, so that flue gas and the abundant heat exchange of heat-transfer pipe.
The both sides of described rustless steel heat collecting sheet body 1 are provided with welding turnup structure, described rustless steel heat collecting sheet body 1
Lower edge is cut off a part, descends most the lowermost end of row's heat-transfer pipe connecting hole to be not more than 8mm to the vertical dimension of lower edge, improves
Heat transfer rate, reduces cost.
In the present embodiment, the preferably lower edge of rustless steel heat collecting sheet body 1 is cut into wavy shaped configuration 4, described waveform
Structure 4 includes external arc 4-1 alternately and Inner arc 4-2 successively, and described external arc 4-1 is corresponding with heat-transfer pipe connecting hole 2, described
