Description
Technical field
The utility model relates to a kind of radiator of infra-red radiation gas-cooker.
Background technology
In the prior art, infra-red radiation gas-cooker has ceramic wafer infrared radiator, and most of heat of fuel gas buring heats infrared radiator, and infrared radiator passes to heating object by the form of radiation heat transfer, has advantages of " energy-saving and environmental protection ".But infrared intensity raying area effect, because infrared radiator swept area is limited to the size of burner, can not accomplish very greatly, therefore exist heat flow to be difficult to do large defect, can not meet the demand of consumer to " vigorous fire "; Swept area is limited, and its radianting capacity is inevitable limited, if do not consider this factor, blindly increases gas flow, only can cause energy loss, causes the thermal efficiency to reduce.For overcoming these defects, spy improves the radiator of infra-red radiation gas-cooker.
Summary of the invention
Technical problem to be solved in the utility model is the radiator that a kind of infra-red radiation gas-cooker will be provided, and it can improve the radianting capacity of radiator.
The utility model solves the technical scheme that its technical problem adopts: it comprises ceramic substrate and nozzles, on substrate, be distributed with some fire output holes and with the staggered spaced connecting hole of fire output hole, nozzles are inserted in connecting hole, the upper surface of the outstanding substrate of nozzles.Nozzles form the concaveconvex structure that height rises and falls on substrate, thereby have increased the effective area of radiation, effectively raise radiation intensity, also make burning more abundant simultaneously, heat flow can be done greatly, reach the object of " vigorous fire, energy-conservation ".
The described nozzles connected portion that plugs and the protuberance composition of serving as reasons, the portion of plugging injects connecting hole interference fit with it, and protuberance is bearing on substrate, and nozzles are provided with the nozzles centre bore with the coaxial setting of connecting hole, and nozzles centre bore runs through the portion of plugging and protuberance.
The bottom of described substrate is provided with reinforcement plate, to improve the mechanical strength of substrate.
Described reinforcement plate is provided with and the connecting hole through hole of corresponding coaxial setting one by one.
The bottom of described nozzles puts in through hole, and concordant with through hole interference fit and bottom.
Described reinforcement plate sticks on substrate.Both adopt the mode of adhesion to fix, not only easy to assembly, and sound construction.
Described reinforcement plate is made up of mullite or aluminium oxide.The mechanical strength of mullite, aluminium oxide is higher, but thermal stability is poor, is not suitable for using as raw material separately, but for the manufacture of reinforcement plate, can improves the mechanical strength of substrate.
Described substrate is made up of cordierite, and nozzles are made up of mullite or aluminium oxide.The substrate made from cordierite, because its thermal coefficient of expansion is low, has Heat stability is good, the feature of long service life.But because the mechanical strength of cordierite is not high, cause radiator in production, transport and routine use process, often can be because damaged by external impacts.The mechanical strength of mullite, aluminium oxide is higher, plugs the nozzles of being made up of mullite or aluminium oxide and can improve the mechanical strength of substrate in fire output hole.
Another technical scheme that the utility model solves its technical problem employing is: it comprises ceramic substrate, and substrate is provided with the jut of some outstanding upper surface of base plate, and is evenly distributed with fire output hole on monoblock substrate.
Described jut and substrate are made up of the composite material of cordierite and mullite or aluminium oxide, and one-body molded.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is axial sectional structure schematic diagram of the present utility model.
Detailed description of the invention: shown in Fig. 1 and Fig. 2, the present embodiment comprises the ceramic substrate 1 of being made up of cordierite and the nozzles 2 of being made up of mullite, on substrate 1, be distributed with some fire output holes 11 and connecting hole 12, connecting hole 12 arranges with the staggered interval of fire output hole 11, and whole substrate 1 is that class is cellular.The bottom adhesion of substrate 1 has the reinforcement plate 3 of being made up of mullite, and reinforcement plate 3 is provided with and connecting hole 12 through hole 31 of corresponding coaxial setting one by one.Nozzles 2 intervals are inserted in connecting hole 12 and the upper surface of outstanding substrates 1, and the bottom of nozzles 2 puts in connecting hole 12 and through hole 31, and with connecting hole 12, through hole 31 interference fit, and the bottom of nozzles 2 is concordant with the bottom of through hole 31.
The nozzles 2 connected portion that plugs and the protuberance composition of serving as reasons, the portion of plugging injects in connecting hole 12, and protuberance is bearing on substrate 1, and nozzles 2 are provided with the nozzles centre bore 21 with the coaxial setting of connecting hole 12, and nozzles centre bore 21 runs through the portion of plugging and protuberance.The protuberance of nozzles 2 is column or taper, and fire output hole 11 and nozzles centre bore 21 can be circular hole, square hole, delthyrium or hex hole, can also be other Common Shape holes.
Substrate 1 upper surface is smooth, and the protuberance of nozzles 2 protrudes from the upper surface of substrate 1, makes the radiating surface of radiator form the space multistory face that height is alternate, has effectively increased the surface area of radiating surface.The space radiation face of above-mentioned design forming, the relative orientation during to external radiation of its concave part, has ensured in photothermal segment set; Ledge is diffuse radiation during to external radiation, makes radiation more even, stable.This structure makes the more effective radiation-absorbing heat of heating object, really reaches " vigorous fire, efficient, energy-conservation ", satisfies the demands of consumers.Meanwhile, fire output hole 11 and nozzles centre bore 21 that height is alternate, three-dimensional combustion system is effectively increased the space of burning, makes burning more abundant.
Substrate 1 is that circle and thickness are 10～20mm, and external diameter is 140～160mm, and the height of projection of nozzles 2 juts is 1.5～2mm.If the height that is 150mm, nozzles 2 juts by the external diameter of substrate 1 be 2mm calculate, its swept area has increased by 40% than unpolarized swept area, in same time radiation-curable go out more heat, so heat flow can be done greatly.Heat flow of the present utility model can be accomplished 3.8kW, and the thermal efficiency, up to more than 75%, can be economized on gas 50% than general gas stove, has improved more than 25% than the infrared radiator of common 3.0kW.
Because the substrate 1 in the utility model adopts cordierite to make, in the middle of mullite and aluminium oxide, mullite not only mechanical strength is high, and thermal coefficient of expansion is also close with cordierite, therefore the radiator that cordierite and mullite combine, combine the feature of cordierite flameholding and mullite high mechanical properties, greatly improved the service life of radiator and the ability that external force resistance impacts.
The utility model is except adopting the height of realizing radiating surface by parts nozzles independently rises and falls, can also on ceramic substrate 1, be provided with some juts of one-body molded and outstanding substrate 1 upper surface with it, then on monoblock substrate 1, be evenly distributed with fire output hole, the height that also can effectively realize radiating surface rises and falls.Now, jut and substrate 1 are made up of the composite material of cordierite and mullite, and wherein cordierite accounts for 20%～80%, and mullite accounts for 80%～20%, and preferably 80% cordierite mixes with 20% mullite.
Above-mentioned embodiment is only also non-limiting for the one of some embodiments, is not departing under the prerequisite of the utility model design philosophy, and the improvement that other personnel make the technical program, should fall into protection domain of the present utility model.
