Abstract
The utility model relates to a fuel gas heat absorption plate, which is provided with at least a row of heat absorption pipe mounting holes. The fuel gas heat absorption plate is characterized in that the bottom of the heat absorption plate is provided with a plurality of arc convexes concentric to the corresponding heat absorption pipe mounting holes and a plurality of concave cambered surfaces in smooth transition with the adjacent arc convexes, and the distance (A) between the lowest point of each arc convex and the edge of the corresponding concentric heat absorption pipe mounting hole is within 10mm. Using the fuel gas heat absorption plate can reduce copper consumption and improve heat efficiency, and the service life of the fuel gas heat absorption plate can be prolonged.
Description
Technical field:
The utility model relates to a kind of combustion gas that is used on the gas heater and use heat absorbing sheet.
Background technology:
Heat exchanger on the gas heater is made up of with the endothermic tube that is contained in the endothermic tube installing hole in the heat absorbing sheet tens of heat absorbing sheets by the endothermic tube installing hole.The durability of heat absorbing sheet promptly uses life relations to arrive the service life of heat exchanger, also is the service life that concerns gas heater.At present, the service life of heat absorbing sheet is shorter.
The utility model content:
The purpose of the utility model is can reduce copper material consumption and can improve the combustion gas in the thermal efficiency and service life and use water heater in order to provide a kind of.
The purpose of the utility model realizes like this:
Heat absorbing sheet is used in the utility model combustion gas; At least one row's endothermic tube installing hole is arranged on the heat absorbing sheet; It is characterized in that having on the heat absorbing sheet bottom surface inner concave arc surface of concentric arc convex surface of a plurality of and corresponding endothermic tube installing hole and a plurality of and adjacent arc convex surface rounding off, the minimum point of arc convex surface and concentric with it endothermic tube installing hole Edge Distance A are in 10mm.
The ultimate range B of the above-mentioned adjacent endothermic tube installing hole in heat absorbing sheet middle part is at 14mm.
The intersection point that intersect on the perpendicular bisector of the above-mentioned heat absorbing sheet top adjacent endothermic tube installing hole line of centres and heat absorbing sheet top and the line C at endothermic tube center are in 40mm.
Above-mentioned heat absorbing sheet is provided with shutter, and with flue gas shunting, Heat-collecting effect is better.。
Above-mentioned heat absorbing sheet is provided with fabrication hole, reduces flow of flue gas speed, improves heating rate.
During burning, at first the flame envelope of flame combustion is near the heat absorbing sheet bottom, and generally about 800-1200 ℃, this temperature range receives the influence of combustion system, oxygen supply mode etc. to the temperature of combustion of natural gas; The endothermic tube that after the heat absorbing sheet heat absorption heat transferred and heat absorbing sheet is linked together, endothermic tube with the water in the heat transferred endothermic tube, heats water again.By calculating heat conducting speed on the theory is 10.6 ㎜/S, is to process with copper material and generally do heat absorbing sheet.The fusing point of the price copper material of copper material is 1083 ℃; And natural gas burning flame envelope temperature is about 800-1200 ℃; Temperature with the flame envelope place within will be in 1S passes; Therefore can not surpass 10 ㎜ in minimum point with concentric with it endothermic tube wire arrangement bore edges distance near the arc convex surface of the flame envelope part of combustion flame, otherwise, easy heat absorbing sheet is burnt out or with the copper material sex change of heat absorbing sheet.
The heat absorbing sheet mid portion is because the bottom has absorbed a part of heat; The temperature at middle part will be hanged down; Generally between 500-800 ℃; So the ultimate range B that the adjacent endothermic tube in heat absorbing sheet middle part is installed between hole wall can not surpass 14 ㎜, otherwise, easy heat absorbing sheet is burnt out or with the copper material sex change of heat absorbing sheet.
Heat absorbing sheet top is owing to bottom, middle part have absorbed a part of heat; The temperature on top will more be hanged down; Generally between 110-300 ℃, in general the solstics can be bigger apart from pipe inner wall according to inference, too greatly again waste material; To the absorption of heat with to emit contribution little, so the line C at crossing intersection point in the perpendicular bisector that adopts the heat absorbing sheet top adjacent endothermic tube installing hole line of centres and heat absorbing sheet top and endothermic tube center is in 40mm.
The utility model combustion gas heat absorbing sheet has the following advantages:
1, improve the thermal efficiency greatly;
2, reduce copper material consumption, cost is low, avoids firing bad, prolonged, durable, long service life;
3, easy to process, safe and reliable.
