Abstract
The utility model relates to a high efficiency heat absorption plate for gas water heaters, belonging to the gas water heater technical field, wherein a heat absorption plate is provided with holes for receiving water tubes. The high efficiency heat absorption plate is characterized in that two adjacent holes on the heat absorption plate are provided with a protrusion for baffling hot air or flame. The high efficiency heat absorption plate has the advantages that the protrusion on the heat absorption plate and the corresponding grooves can improve the heat absorption area of the heat absorption plate and can baffle and disturb flame and hot airflow, to prolong the residence time of the flame and hot airflow near the heat absorption plate, to make the temperature on the heat absorption plate uniform, improve the synthetic heat efficiency of a gas water heater, save energy and satisfy the national energy-saving consumption reduction policy, thus is beneficial for wide application on various gas water heaters.
Description
Technical field:
The utility model relates to the gas heater technical field, refers in particular to a kind of efficient heat absorbing sheet of gas heater.
Background technology:
At present, people are in order to live or to wash and use hot water, mostly use gas heater to come water is heated, advantage is that firing rate is fast, be convenient to regulate the temperature of heated water, easy to use, but, minimizing gradually along with global energy, the anxiety of petroleum-based energy particularly, country adjusts the national standard of using gas heater, and for example: originally the national standard of the thermal efficiency of gas heater is 80%, and the national standard of the thermal efficiency of adjusted gas heater is: one-level: 94%; Secondary: 88%; Three grades: 84%, promptly by existing national standard requirement, the thermal efficiency of gas heater is minimum should to be reached more than 84% or 84%, and the thermal efficiency of the at present domestic gas heater that generally uses is all below 84%, actual between 82%-84%, like this, make domestic most of product become the product that does not meet national standard.
03203267.6 number Chinese patent discloses a kind of heat absorbing sheet and the built-in gas heater of heating tube of gas heat exchanger, the primary structure of gas heater includes burner, heat absorbing sheet, coil pipe and control element etc. thereof, heat absorbing sheet is set on the coil pipe in groups, burner heats heat absorbing sheet and coil pipe by combustion gas or natural gas burning, thereby realize the water that flows in the coil pipe is heated, and the thermal efficiency of gas heater depends on the shape of heat absorbing sheet on the gas heater, referring to Fig. 1-3: the heat absorbing sheet 1 on the present gas heater substantially all is to offer the hole 2 that coil pipe can penetrate on a certain size planar metal sheet material, around planar metal sheet material hole simultaneously, be provided with technology limit 3, so that heat absorbing sheet is welded on the metal coil pipe successively, its weak point is: owing to the flame of combustion gas or combustion of natural gas and thermal current only are subjected to the disposable cutting restriction of stopping of coil pipe and heat absorbing sheet to flow out gas heater, the time that stops in gas heater is short, temperature distributing disproportionation on the heat absorbing sheet is even, the temperature difference is big, cause the endothermic effect of heat absorbing sheet poor, the thermal efficiency is low, wastes energy.
Summary of the invention:
The purpose of this utility model provides a kind of efficient heat absorbing sheet that can effectively prolong the heat absorbing sheet heat absorption time, improve the gas heater of heat absorption efficiency
The utility model is achieved in that the efficient heat absorbing sheet of gas heater, be on heat absorbing sheet, to offer the hole that can penetrate water pipe, it is characterized in that between two that face mutually on the described heat absorbing sheet holes that can penetrate water pipe, being provided with the projection that can stop that hot gas or flame flow.
Above-mentioned projection is parabolic body or semiellipse spheroid or truncate quadrangular pyramid body or cuboid or the cylinder or the frustum of a cone.
Be to have with described to be raised with identical shaped groove in the corresponding position that the projection on the another side of projection one side is arranged on the above-mentioned heat absorbing sheet.
The outstanding compared to existing technology advantage of the utility model is:
1, because the projection on the heat absorbing sheet of the present utility model reaches the setting with its corresponding groove, the one, itself increased the endotherm area of heat absorbing sheet, make endothermic effect improve, the 2nd, projection and groove have flame and thermal current and stop and the flow-disturbing effect, make extend flame and the thermal current time of staying in heat absorbing sheet, endothermic effect improves, the 3rd, projection and groove are to the flow-disturbing effect of flame and thermal current, make that the Temperature Distribution on the heat absorbing sheet is more even, endothermic effect improves, above comprehensive function, the integrated heat efficiency that has formed gas heater is increased to more than 84% of national Specification.
2, the utility model is simple in structure, and is easy to manufacture, and firing rate is fast, the heat absorption efficiency height, and fuel savings is convenient to apply on various types of gas heaters.
Description of drawings:
Fig. 1 is the structural front view of background technology;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1;
Fig. 4 is a schematic perspective view of the present utility model.
The specific embodiment:
With specific embodiment the utility model is further described below:
Referring to Fig. 4: the efficient heat absorbing sheet of gas heater, be on heat absorbing sheet 10, to offer the hole 20 that can penetrate water pipe, it is characterized in that being provided with between two that face mutually on the described heat absorbing sheet 10 holes 20 that can penetrate water pipe the projection 30 or 31 that can stop that hot gas or flame flow, that is: projection 30 or 31 is arranged on the big location between two water pipes perforation 20 of facing mutually.
Above-mentioned projection 30 or 31 is parabolic body or semiellipse spheroid or truncate quadrangular pyramid body or cuboid or cylinder or the frustum of a cone or other shape.
On the another side that projection 30 or 31 one sides are arranged on the above-mentioned heat absorbing sheet 10 is to have and described protruding 30 or 31 identical shaped groove is arranged with projection 30 or 31 corresponding position.
The direction of arrow among the figure is represented the flame of gas heater and the flow direction of thermal current.
Because the projection on the heat absorbing sheet reaches the setting with its corresponding groove, increased the endotherm area of heat absorbing sheet, when flame and thermal current when the direction of arrow flows, projection and groove have flame and thermal current and stop and the flow-disturbing effect, make extend near flame and the thermal current time of staying heat absorbing sheet, Temperature Distribution on the heat absorbing sheet is more even, make the integrated heat efficiency of gas heater improve, the thermal efficiency of the gas heater of the regulation that is up to state standards must be at the index request more than 84%, simultaneously, fuel savings, meet country about energy-saving and cost-reducing industrial policy, be convenient to apply on various types of gas heaters, installation method of the present utility model is identical with the installation method of the heat absorbing sheet of routine, no longer describes in detail herein.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
