Abstract

The utility model particularly relates to a metal honeycomb heating body provided with fins and through holes used in a channel on a gas appliance. The metal honeycomb heating body is characterized in that a metal foil plate flat belt is pressed into a metal foil plate corrugated belt by a specially-made pressure wave machine; the metal honeycomb heating body has the technical requirements that the fins and the through holes are respectively pressed on the two inclined side walls of the corrugated outline of the metal foil plate corrugated belt; the metal foil plate flat belt and the metal foil plate corrugated belt provided with the fins and the through holes on the two inclined side walls are overlapped and welded in a winding way, so that the metal honeycomb heating body provided with the fins and the through holes used in the metal honeycomb carrier channel can be prepared. After the scheme is adopted, the heat conductivity of the metal honeycomb heating body is effectively reduced, and the metal honeycomb heating body has a good current stabilization function; under the condition that a gas current stabilization net is not arranged on the lower surface of the metal honeycomb heating body, a metal honeycomb burner also can realize stable and efficient combustion.

Description

Be used in the interior metal honeycomb heating body with fin and through hole of gas appliance upper channel

Technical field:

The utility model patent relates to a kind of metal honeycomb heating body being used on gas appliance, particularly relates to a kind of metal honeycomb heating body being used on Domestic far-infrared line gas stove burner.

Background technology:

The existing metal honeycomb heating body being used on gas appliance burner on market, large is that base growth is got up mainly with automobile three-way catalysts with metal beehive carrier, but due to the automobile metal honeycomb substrate of copying by rote simply, do not have to carry out structural design and optimization of material selection by self use principle, make metal beehive carrier in use occur series of problems.Main flow household cooking utensil burner metal honeycomb heating body on existing market, mostly adopt the superimposed winding welding of the dull and stereotyped band of sheet metal and sheet metal corrugated ribbon to make metal beehive heating carrier, then at metal beehive heating carrier lower surface, weld the stainless (steel) wire of one deck densification, this layer of stainless (steel) wire plays current stabilization and heat-blocking action, but because metal material has the characteristic of thermal boundary shrinkage, metal material has the advantages that thermal conductivity is high simultaneously, under the service condition of long-term alternating hot and cold, the current stabilization heat-shielding net of metal beehive carrier lower surface very easily comes off, cause metal beehive burner generation tempering phenomenon, metal beehive burner cannot be worked.In order to overcome the defect of technical scheme that existing product adopts, I have applied for being used in the metal honeycomb heating body patent (ZL201220605221.5) on gas appliance with secondary current-stabilizing structure, the technical essential of this patent is effectively to reduce the thermal conductivity of metal beehive carrier, concrete measure is by changing the structural design of metal beehive carrier, effectively reduce the thermal conductivity of metal beehive carrier, at this moment metastable gas drift net or current stabilization sheet just needn't weld with metal beehive carrier lower surface, both can reach current stabilization and effect of heat insulation, only need that metastable gas drift net is arranged on to the lower surface of metal beehive carrier or apart from lower surface a distance, this design efficiently solves the existing technology hidden danger that is used in metal beehive heating carrier on gas-fired equipment burner on market, but also there is certain technological deficiency in above technical scheme, because gas appliance is more severe by metal beehive burner environment for use, under the service condition of long-term alternating hot and cold, stainless steel metastable gas drift net or current stabilization sheet be Corrosion blockage very easily, cause metal beehive burner to work.

Summary of the invention:

In order to solve the technological deficiency of metal honeycomb heating body for existing household cooker, the utility model patent has adopted the metal honeycomb heating body new technology with multiple current-stabilizing structure, in metal beehive heating carrier inside pore channel, be provided with a plurality of fins, the carrier inside of metal beehive heating simultaneously passage has the structure of being interconnected, make metal beehive carrier itself possess current stabilization and heat insulating function, even if there is not like this tempering phenomenon in the situation that metal beehive heating carrier lower surface does not arrange combustion gas flow straightener yet, metal beehive burner both can have been realized stable, efficient burning, more than design makes metal beehive heating carrier have multiple flow stabilizing function, improve the preparation technology of metal beehive heating carrier upper surface catalyst coatings simultaneously, make catalyst coatings bonding more firm, use the base metal catalysts that adds a small amount of rare earth oxide, guaranteeing under the rational prerequisite of cost performance, it is good that this rare earth oxide base metal catalysts has ignition performance, there is higher three-effect catalysis active, have wider can action pane, more than design can make metal beehive combustor stability better, efficient energy-saving, technique is the upgraded product of metal beehive heating carrier for gas appliance burner on existing market.

Technical scheme:

The technical scheme that this patent adopts is: be used in the interior metal honeycomb heating body with fin and through hole of gas appliance upper channel, it is characterized in that: with punch, the dull and stereotyped band of metal foil plate is pressed into metal foil plate corrugated ribbon, its specification requirement is to suppress fin and through hole on two canting walls of metal foil plate corrugated ribbon corrugated contours, by the dull and stereotyped band of metal foil plate and on two canting walls with the superimposed winding welding of metal foil plate corrugated ribbon of fin and through hole, be formed in metal beehive carrier passage the metal honeycomb heating body with fin and through hole.

Described metal honeycomb heating body passage is interior with a plurality of fins and through hole.

The upper surface of described metal honeycomb heating body is coated with catalyst coatings.

The inner ring of described metal honeycomb heating body is provided with retainer ring.

The outer ring of described metal honeycomb heating body is provided with expansion ring.

Described expansion ring is provided with expansion joint.

Beneficial effect:

The utility model patent efficiently solves the weak point of mentioning in background technology, changed the structural design of metal beehive heating carrier, make metal beehive heating carrier self there is current stabilization and heat insulating function, in the situation that combustion gas flow straightener is not set, metal beehive burner both can be realized stable, efficient burning, thoroughly solved the technology hidden danger that metal beehive heating carrier lower surface metastable gas drift net easily comes off, burn into stops up, made metal beehive heating carrier can realize standardization, modularization processing and fabricating.
