A plurality of heat exchanging tube holes are arranged on heat exchanging plates with heat cutting off holes, and are densely and vertically distributed in a heat exchanger, a plurality of heat cutting off holes are arranged at the lateral parts or the upper lateral parts of the heat exchanging tube holes, a bending edge is arranged at the edge at the side close to the heat exchanging tube of the heat cutting off hole, or arranged at the periphery position of the whole hole. The height of the heat cutting off hole is slightly smaller than the space length between two heat exchanging plates. The utility model replaces the original heat exchanging plates with the heat exchanging plates provided with the heat exchanging tube holes, and the heat efficiency can be significantly enhanced under the premises that the shape and the volume of the heat exchanger are not changed, and the material is not increased.
Description
Technical field
The utility model relates to gas heater, refers in particular to the improvement to the heat exchanger fin structure in the water-heater heat-exchanging device.
Background technology
Heat exchanger is a vitals in the fast gas heater, and its effect is that the heat that produces during fuel gas buring is transferred in the water pipe to obtain our required hot water.The general structure of heat exchanger 1 as shown in Figure 1, be provided with plate-like heat exchanger tube 3 in the heat exchanger shell 2, for improving heat exchange efficiency, in housing, vertically be arranged with simultaneously some heat exchanger fins 4 thick and fast, this heat exchanger fin in the form of sheets, which is provided with some pores 5, plate-like heat exchanger tube 3 is by passing in the described pore 5, and welded together in pore 5 places and heat exchanger fin 4 driving fits ground.When the high-temperature gas that produces during fuel gas buring passed through heat exchanger 1 from bottom to top, most of heat was absorbed by heat exchanger fin 4, and was transferred to cold water heating in 3 pairs of pipes of plate-like heat exchanger tube, and waste gas is then discharged from flue by heat exchanger 1 top.Desire further to improve heat transfer efficiency, generally will consider the effective heat transfer area that increases heat exchanger fin 4.But will inevitably increase the copper material consumption like this, increase product cost, small product size is increased.
Summary of the invention
The purpose of this utility model be propose a kind of with the dam heat exchanger fin in hole of heat, by above contiguous described heat exchange pore on the heat exchanger fin, locating to increase some heat hole of damming, form the guide frame that dams of heat on the exchange backing, make the control transfer of heat approach more reasonable, thereby under the prerequisite that does not increase heat transfer area, effectively improve the heat laser propagation effect, further improve the heat exchange efficiency of heat exchanger.
Of the present utility model a kind of with the dam heat exchanger fin in hole of heat, which is provided with some heat exchange pores, vertically be arranged in the heat exchanger thick and fast, it is characterized in that: above the side of contiguous described heat exchange pore or side, locate to offer some heat hole of damming, and flanging is arranged, or flanging is arranged at the periphery place in whole hole in the dam edge of nearly heat exchanger tube side in hole of described heat.The dam flanging height in hole of described heat is slightly less than two spacings between heat exchanger fin.
The described heat hole of damming can be a complete circular hole, on the whole periphery of described circular hole flanging is arranged; The described heat hole of damming also can be an imperfect hole, on the whole periphery in described imperfect hole flanging is arranged; The described heat hole of damming also can be the elongated hole of a rectangular opening or other shapes, on the nearly heat exchange pore side edge on one side in described hole flanging is arranged.
Useful effect of the present invention is: by adopting the heat exchanger fin in the hot hole of damming of band of the present utility model, owing on heat exchanger fin, be provided with some heat hole of damming, formation is to the guide effect of damming of heat, thereby changed the direction of motion of hot-fluid, make thermal current center on heat exchanger tube and flow, improve thermograde, thereby improve effective and reasonablely around the thermograde of heat exchanger tube periphery around the heat exchanger tube periphery, the heat that produces when making fuel gas buring more effectively transmits feedwater, has improved control transfer of heat efficient.By adopting the dam heat exchanger fin in hole of band heat of the present utility model to replace original heat exchanger fin, at the shape that does not change heat exchanger, volume with do not increase under the prerequisite of material, the thermal efficiency can be significantly improved.

The specific embodiment
An embodiment of the present utility model is as Fig. 3 and Fig. 4.
At first, above the side between two holes of last row heat exchange pore 5a-5c, be provided with 2 heat hole B that dams.This heat hole B that dams is a complete circular hole, and dashing at the whole periphery of described hole B has flanging 6.Referring to Fig. 4 B.
Secondly, between two holes of arranging heat exchange pore 5d-5f down, be provided with 2 heat hole A that dams above the side partially.This heat hole A that dams is one and has the imperfect circular hole of breach 7 at the hole downside, and dashing at the periphery of described hole A has flanging 6.Referring to Fig. 4 A.
Above the side between two holes of heat exchange pore 5a-5f, be provided with 8 heat hole C that dams again.The described heat hole C that dams is the elongated hole of a rectangular opening or other shapes, on one side of nearly heat exchange pore one side in described hole flanging 6 is arranged.Referring to Fig. 4 C.
At the shape that does not change original heat exchanger, volume with do not increase under the prerequisite of copper material consumption, only by the dam heat exchanger fin in hole of the band heat that adopts present embodiment, by test, the thermal efficiency can improve more than 5 percentage points.When having improved the thermal efficiency, also saved the energy, reduced toxic emission.
