Abstract
The invention particularly relates to a metallic honeycomb-like heating body for a gas appliance and a manufacturing method thereof. The manufacturing method comprises the steps of: firstly, calendaring a metallic sheet with a metal calendaring method to obtain punctures arranged at intervals according to a certain rule, then excessively pressing the metallic sheet to obtain a curved corrugated sheet, and winding and welding a single, a pair of or a plurality layers of the metallic curved corrugated sheets to manufacture the metallic honeycomb-like heating body, or interlacing and superposing the metallic curved corrugated sheets to manufacture the metallic honeycomb-like heating body through welding, wherein channels are formed among curved corrugated lines on each metallic sheet, the channels on the upper and lower ends of the metallic honeycomb-like heating body are arranged vertically and are in smooth transitional connection with curved channels in the middle of the metallic honeycomb-like heating body, the punctures in each metallic sheet can ensure that the internal channels of the metallic honeycomb-like heating body are communicated mutually, so that stereoscopic honeycomb-like mesh holes are formed inside the metallic honeycomb-like heating body, and the heat conductivity of the metallic honeycomb-like heating body can be reduced effectively while the flow stabilization function of the metallic honeycomb-like heating body is improved.
Description
Technical field:
The present invention relates to a kind of gas appliance metal honeycomb heating body and preparation method thereof, particularly Domestic far-infrared line kitchen range metal honeycomb heating body and preparation method thereof.
Technical background:
Existing gas appliance adopts straight line ripple sheet metal and metal plate thin slice to carry out curling with metal honeycomb heating body or the docking welding fabrication mostly on the market, and the superimposed docking welding fabrication of the straight line ripple sheet metal of employing is also arranged.The metal honeycomb heating body of above form does not have flow stabilizing function, also has the too high easy generation tempering phenomenon of metal honeycomb heating body thermal conductivity, mostly adopt at the stainless (steel) wire of metal honeycomb heating body lower surface welding one deck densification or increase the metal foam of one deck densification at the metal honeycomb heating body lower surface for solving the above difficult problem, play current stabilization and heat-blocking action, but there is very large technology hidden danger in above design.
Summary of the invention:
The object of the invention is to overcome existing gas appliance with the weak point of metal honeycomb heating body, provide a kind of not only metal honeycomb heating body flow stabilizing function well can also effectively reduce simultaneously the thermal conductivity of metal honeycomb heating body.
Technical scheme:
The technical solution adopted in the present invention is: a kind of gas appliance metal honeycomb heating body and preparation method thereof, its preparation method is: at first adopt the rolling metal method with the sheet metal spreading go out acanthopore again superpressure go out the curve ripple, make the metal curve corrugated plate with acanthopore, adopt single, a pair of or multiple layer metal curve corrugated plate twines welding or metal honeycomb heating body is made in interlaced stack welding, curve ripple on the described sheet metal is formed with passage each other, the described channel vertical setting that is positioned at the metal honeycomb heating body top and bottom, the described vertically disposed passage in metal honeycomb heating body top and bottom that is positioned at is connected with the curved channel junction rounding off that is positioned at the setting of metal honeycomb heating body mid portion.
The described acanthopore that has the space to be crisscross arranged at metal curve corrugated plate.
Described jag part and peak base section in curve ripple corrugated contours is provided with groove, is provided with acanthopore in groove, the setting that is interspersed of groove space.
Described two canting walls at the curve ripple are arranged at intervals with convex or/and acanthopore.
Described convex is garden shape, triangle or polygon.
Described acanthopore is hole, garden, tri-angle-holed or polygonal hole.
The curve ripple corrugated contours that arranges on the described metal curve corrugated plate is trapezoidal, triangle or sinusoidal waveform.
Described metal honeycomb heating body carries out curling welding by pair of metal curve corrugated plate, and the curve ripple on the pair of metal curve corrugated plate is staggered diagonal configuration each other.
Beneficial effect:
The present invention makes with the sheet metal of curve ripple owing to metal honeycomb heating body adopts, the carrier passage becomes the curved slot passage by the straight hole passage in past, its advantage is that the curved slot passage plays flow stabilizing function to premixed gas, but the curve ripple is the turbulization effect also, the acanthopore that is arranged on simultaneously on the sheet metal can make the carrier inside passage be interconnected, make the three-dimensional honeycomb mesh of the inner formation of metal beehive carrier, when having improved the metal honeycomb heating body flow stabilizing function, also can effectively reduce the thermal conductivity of metal beehive carrier, premixed gas can both be flowed on all directions of channel interior mutually, also can make the premixed gas of initial mixing inequality obtain partial-compensation when playing flow stabilizing function, acanthopore plays the effect that reduces metal honeycomb heating body thermal conductivity and current stabilization simultaneously, prevent that tempering phenomenon from producing, heating carrier combustibility is more stable.
