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 holes for receiving water tubes, two adjacent holes on the heat absorption plate are provided with a windshield for baffling flame or hot airflow, the heat absorption plate is provided with holes at the back of the non-windward surface of the windshield. The high efficiency heat absorption plate has the advantages that the windshields on the heat absorption plate can baffle and disturb flame and hot airflow, and the holes on the heat absorption plate can make the flame and hot airflow to form series flow on the front and back surfaces of the heat absorption plate, to make the temperature distribution on the heat absorption plate uniform, prolong heat absorption time, improve synthesis heat efficiency, save fuel and satisfy the national energy-saving consumption reduction policy, thus is beneficial for wide application on various gas water heaters.

Description

The efficient heat absorbing sheet of gas heater

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 deep bead that can stop that flame or hot gas flow, on heat absorbing sheet, the rear portion of the non-windward side of deep bead offers porose.

Above-mentioned deep bead is the combination of strip or strip and annular, the circular and tetragonal hole with the corresponding Kong Zewei of the deep bead of annular and strip.

The deep bead and the airflow direction of above-mentioned strip have angle.

Above-mentioned tetragonal hole is the hole of rectangle.

The outstanding compared to existing technology advantage of the utility model is:

1, because the deep bead on the heat absorbing sheet of the present utility model, flame and thermal current had stop and the flow-disturbing effect, a plurality of quadrilateral holes can make flame and the thermal current tow sides crossfire at heat absorbing sheet, above-mentioned stop, flow-disturbing and crossfire result, make that the Temperature Distribution on the heat absorbing sheet is more even, flame and the thermal current flowing time lengthening on heat absorbing sheet, the integrated heat efficiency of gas heater more than 84% of regulation that is up to state standards.

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.

The specific embodiment:

With specific embodiment the utility model is further described below:

Referring to Fig. 4-6: 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 between two that face mutually on the described heat absorbing sheet 10 holes 20 that can penetrate water pipe, being provided with the deep bead 40,41,42 that can stop that flame or hot gas flow, on heat absorbing sheet 10, the rear portion of the non-windward side of deep bead 40,41,42 offers porose 30,31,32.

Above-mentioned deep bead 40,41,42 is the combination of the deep bead 41 of the deep bead 40,42 of strip deep bead 40,42 or strip and annular, with the hole 31 and the tetragonal hole 30,32 of deep bead 40,41, the 42 corresponding Kong Zewei circles of annular and strip.

The deep bead 40,42 and the airflow direction of above-mentioned strip have angle.

Above-mentioned tetragonal hole the 30, the 32nd, the hole of rectangle.

Because the deep bead 40 on the heat absorbing sheet 10,41, stopping and flow-disturbing of the 42 pairs of flame and thermal current, hole 30,31,32 can make flame and the thermal current tow sides crossfire at heat absorbing sheet 10, make that the Temperature Distribution on the heat absorbing sheet 10 is more even, flame and the thermal current flowing time lengthening on heat absorbing sheet 10, 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 on various types of gas heaters, apply.
