Description
Technical field
The utility model relates to the heat exchanger of gas-heating water heater or gas instantaneous water heater.
Background technology
Along with world energy supplies is nervous, under the rare day by day background of the energy, energy-conserving and environment-protective are rooted in the hearts of the people, and the energy-conserving and environment-protective product is vigorously advocated in countries in the world.In burnt gas wall hanging furnace and gas instantaneous water heater product; The lifting of heat exchanger efficiency is energy-conservation significant to entire product, and heat exchanger commonly used in this series products is finned copper heat exchanger, and it includes the heat exchange fin of some parallel interval and the heat exchanger tube that some ends are communicated with; Have the heat exchanger tube perforation of arrangement in a row on the heat exchange fin; The heat exchanger tube perforation that heat exchanger tube passes heat exchange fin in a row interts on heat exchange fin, and the cooling medium-hydrophily of this heat exchanger flows in heat exchanger tube, and the heat that fuel gas buring produces is by the hydrophily of air in heat exchanger passes to heat exchanger tube; Heat exchange fin plays the increase heat exchange area, reduces the effect of air side thermal resistance.Mostly the heat exchange fin that uses at present is flat construction; Heat transfer process air temperature difference because of heat exchanger and air between heat exchange fin forms mobile stably; This flowing slows down with dwindling gradually of the temperature difference, and boundary layer progressive additive, thermal resistance that air is formed on the heat exchange fin surface increase, and have influenced the heat exchange effect of heat exchanger; For this reason, be necessary that the heat exchanging device improves.
Summary of the invention
The purpose of the utility model is to propose a kind of heat exchange fin that is used for gas-heating water heater or gas instantaneous water heater, and it can effectively improve the heat exchange efficiency of heat exchanger.
The purpose of the utility model can realize through following technical scheme:
A kind of heat exchange fin that is used for gas-heating water heater or gas instantaneous water heater; Comprise the fin substrate; Have the heat exchange pore on this fin substrate; It is characterized in that: the two sides of fin substrate has near the salient point that is distributed in the heat exchange pore, and the height of said salient point is 1-3mm, and the centre distance of two adjacent salient points is not less than 4mm.
The place, the salient point back side of fin substrate is a concave point, and salient point and concave point are alternate.
On the heat exchanger of combustion gas firing equipment, the utility model is installed, in using heat transfer process, when hot-air flows between heat exchange fin; The heat exchange fin of surface irregularity makes the disturbed wadding of air-flow disorderly; Destroy the boundary layer of air-flow, strengthened the heat exchange of hot-air and heat exchange fin, in addition on the heat exchange fin surface; Salient point on the heat exchange fin has also increased the heat exchange area of air and heat exchange fin, has further improved the heat exchange efficiency of heat exchanger.
The utlity model has following substantive distinguishing features and progress:
1. after the utility model is applied to the heat exchanger of combustion gas firing equipment, can improve the heat exchange efficiency of heat exchanger;
2. the utility model can increase the heat exchange area of heat exchanger, further improves the heat exchange efficiency of heat exchanger;
3. the utlity model has simple in structurely, be easy to produce characteristics easy for installation.

Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the stereogram of Fig. 1 structure.
Fig. 3 is the schematic partial cross-sectional view of Fig. 1 structure.
Fig. 4 is another structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
With reference to figure 1, Fig. 2 and Fig. 3, a kind of heat exchange fin that is used for gas-heating water heater or gas instantaneous water heater comprises fin substrate 1; Have heat exchange pore 2 on this fin substrate 1, the two sides of fin substrate 1 has near the salient point 3 that is distributed in the heat exchange pore 2, and said salient point 3 is drawing; The place, salient point 3 back sides of fin substrate 1 is a concave point 30, and salient point 3 is alternate with concave point 30, and promptly salient point 3 and concave point 30 respectively are distributed in the two sides of fin substrate 1; In the present embodiment, said salient point 3 is a hemispherical, and the overall diameter D of salient point 3 bottom surfaces is 2mm; The height H of salient point 3 is 1mm, and the centre-to-centre spacing of two salient points is greater than 4mm.
The heat exchange fin of present embodiment and set of heat exchange tubes are dressed up heat exchanger to be installed in the combustion gas firing equipment and to use; In the heat transfer process, the air that carries heat flows between heat exchange fin, and the heat in the air is through heat exchange fin → heat exchange tube wall or directly pass to the hydrophily in the heat exchanger tube through the heat exchange tube wall; Air-flow is when contacting with heat exchange fin; Because heat exchange fin has salient point, concave point on the heat exchange fin and salient point make the disturbed wadding of air-flow disorderly, and the heat exchange efficiency of heat exchanger is improved; In addition, concave point on the heat exchange fin and salient point have also increased the heat exchange area of air and heat exchange fin, and be also helpful to the heat exchange effect that improves heat exchanger.
Salient point in the present embodiment can also be a rectangle, cylindrical etc.
With reference to figure 3, the difference of present embodiment and embodiment 1 is: have 2 row's heat exchange pores 2 on the heat exchange substrate 1, be applied to be provided with the heat exchanger of 2 row's heat exchanger tubes.The method for using of present embodiment is identical with embodiment 1 with result of use.
