Abstract
The invention relates to an efficient heat absorption fin for a fuel gas wall hanging stove. The efficient heat absorption fin for the fuel gas wall hanging stove is provided with at least one row of heat absorbing tube installation holes, and is characterized in that a plurality of arc convex faces respectively concentric with the corresponding heat absorbing tube installation holes, and inward concave arc faces formed by smooth transition of adjacent arc convex faces are disposed on the bottom face of the heat absorption fin, at least two shutters which are arranged in parallel mode from the top down are installed between each two adjacent heat absorbing tube installation holes, and faces of the same sides of the shutters which are arranged in parallel mode form cambered surfaces which are respectively concentric with cambered surfaces of the heat absorbing tube installation hole adjacent to the shutters. The efficient heat absorption fin for the fuel gas wall hanging stove can reduce consumption of copper material and improve heat exchange rate and service life.
Description
technical field:
What the present invention relates to is a kind of for the high efficiency heat absorption sheet of the burnt gas wall hanging furnace on burnt gas wall hanging furnace.
background technology:
Heat exchanger on burnt gas wall hanging furnace device is to be comprised of the tens of heat absorbing sheets by endothermic tube installing hole and the endothermic tube being contained in the endothermic tube installing hole in heat absorbing sheet.The durability of heat absorbing sheet is used Life Relation to the service life of heat exchanger, is also the service life of burnt gas wall hanging furnace.
summary of the invention:
The object of the invention is can reduce copper material consumption and can improve the burnt gas wall hanging furnace high efficiency heat absorption sheet in rate of heat exchange and service life in order to provide a kind of.
The object of the present invention is achieved like this:
Burnt gas wall hanging furnace of the present invention high efficiency heat absorption sheet, on heat absorbing sheet, there is at least one row's endothermic tube installing hole, it is characterized in that having on heat absorbing sheet bottom surface the inner concave arc surface of the concentric arc convex surface of a plurality of and corresponding endothermic tube installing hole and adjacent arc convex surface rounding off, between adjacent endothermic tube installing hole, the blind window that at least two fans are arranged in parallel is housed, the ipsilateral of the blind window being arranged in parallel forms the cambered surface concentric with the cambered surface of adjacent endothermic tube installing hole.
Above-mentioned heat absorbing sheet inner concave arc surface bottom is 3～4mm with the distance of adjacent blind window bottom.
On above-mentioned heat absorbing sheet, the distance of endothermic tube installing hole hole wall and adjacent blind window cambered surface is 2.5～3.5mm.
On above-mentioned heat absorbing sheet, between adjacent installing hole, there are three fan blind windows.
The blind window angle arranging on above-mentioned heat absorbing sheet is 32～38 ℃, digs height and is being 1.8～2.5mm.
The blind window spacing arranging on above-mentioned heat absorbing sheet is 3～4mm.
On above-mentioned heat absorbing sheet, louver window width is 3～4mm.
The correcting hole that has diameter 5～6mm on above-mentioned heat absorbing sheet, carries out correcting during convenient processing heat absorbing sheet, prevents that heat from gathering, and it is overheated to avoid occurring.
On above-mentioned heat absorbing sheet, be provided with blind window, by flue gas shunting and flow-disturbing, change the distance of flow of flue gas, reduce flow of flue gas speed, improve heating rate, Heat-collecting effect is better.
Hot gas passes through between heat absorbing sheet, exchanges again with shutter flue gas, has back and forth repeatedly, by flue gas shunting and flow-disturbing, changes the distance of flow of flue gas, reduces flow of flue gas speed, improves heating rate, and Heat-collecting effect is better
During burning, first the flame envelope of flame combustion is near heat absorbing sheet bottom, and the temperature of combustion of natural gas is generally 800-1200 ℃ of left and right, and this temperature range is subject to the impact of combustion system, oxygen supply mode etc.; After heat absorbing sheet heat absorption, transfer heat to the endothermic tube linking together with heat absorbing sheet, endothermic tube transfers heat to the water in endothermic tube again, and water is heated.By calculating heat conducting speed in theory, being 10.6 ㎜/S, is to make with copper material and generally do heat absorbing sheet.The fusing point of the price copper material of copper material is 1083 ℃, and the burning flame envelope temperature of natural gas is 800-1200 ℃ of left and right, the temperature at flame envelope place is passed within be in 1S, otherwise, easily heat absorbing sheet is burnt out or by the copper material sex change of heat absorbing sheet.
Combustion gas heat absorbing sheet of the present invention has the following advantages:
1, greatly improve rate of heat exchange;
2, reduce copper material consumption, cost is low, avoid firing bad, long service life;
3, easy to process, safe and reliable.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A cutaway view of Fig. 1.
Fig. 3 is blind window, position of mounting hole graph of a relation.
the specific embodiment:
Referring to Fig. 1～Fig. 3, the present embodiment burnt gas wall hanging furnace high efficiency heat absorption sheet, has row's endothermic tube installing hole 1 on heat absorbing sheet.The inner concave arc surface 3 that has the concentric arc convex surface 2 of a plurality of and corresponding endothermic tube installing hole and adjacent arc convex surface rounding off on heat absorbing sheet bottom surface.The blind window 4 that three fans are arranged in parallel is up and down housed between adjacent endothermic tube installing hole.The ipsilateral of the blind window being arranged in parallel forms the cambered surface 6 concentric with the cambered surface 5 of adjacent endothermic tube installing hole.Heat absorbing sheet inner concave arc surface bottom is 4mm with the distance B of adjacent blind window bottom.On heat absorbing sheet, the distance C of endothermic tube installing hole hole wall and adjacent blind window cambered surface is 3mm.The blind window angle arranging on heat absorbing sheet is 35 ℃, and digging height H is 2mm.The blind window space D arranging on heat absorbing sheet is 4mm.On heat absorbing sheet, louver window width E is 3mm.On heat absorbing sheet, having diameter is the correcting hole 7 of 5mm.
