Abstract
The utility model provides a stainless steel bellows spiral heat exchanger, which comprises a combustion chamber and a heat exchanger, wherein the combustion chamber comprises a cylinder body, a top cover and a bottom cover; the heat exchanger is a spiral tube formed by spirally winding a stainless steel bellows; one end of the stainless steel bellows forms a water inlet of the spiral tube, and the other end of the stainless steel bellows forms a water outlet of the spiral tube; a clearance is arranged between the spiral tube and the cylinder body; a condensed water drain opening is formed on a chassis between a gas guide tube and the cylinder body; and the heat exchanger further comprises a heat insulating board arranged in the spiral tube. As the structure is adopted, fuel gas is combusted in the spiral tube at the lower part of the heat insulating board to heat an inner cavity of the spiral tube at an angle of 360 degrees, and waste heat enters the part between the spiral tube and the cylinder body via clearances among screw pitches of the spiral tube to reheat the spiral tube, so that the heat absorption area is expanded and the heat efficiency is improved; smoke gas with the waste heat enters the spiral tube at the upper part of the heat insulating board from the part between the spiral tube and the cylinder body to preheat the spiral tube; and the heat absorption area is increased and the heat absorption efficiency is improved.
Description
Technical field
The utility model relates to a kind of heat exchanger, especially the heat exchanger of the blowing type gas water heater of condensing and gas two-purpose stove.
Background technology
The water heater of traditional combustion gas, gas two-purpose stove, its heat exchanger generally adopts the copper heat exchanger, and traditional heat exchanger is made up of outer cover, dish case pipe, heat absorption fin.Heat exchanger covers burner, and machine when burning is by the heat absorption collecting fins heat in the heat exchanger upper end.Cold water absorbs the heat of fin through the coil pipe of over-heat-exchanger, makes cold water be converted into hot water.
General traditional blowing-type water heater is placed air blast in the burner lower end.During machine works, air blast is forced flue gas to discharge machine through heat-exchanger fin and collection flue.
And the water heater of condensing is to place a heat dump on common heat exchangers again, absorbing unnecessary heat once more, and then gets rid of discarded through the collection flue.
Traditional blowing type gas water heater, gas two-purpose furnace heat exchanger exist heat exchanger effectiveness low.Condensing blowing type gas water heater, gas two-purpose furnace heat exchanger owing to settle heat dump more, and cost has improved again greatly.
Summary of the invention
The purpose of this utility model is: a kind of corrugated stainless steel tubing votator is provided, and it not only can absorb heat by 360 degree, utilizes waste heat, and simple in structure, and cost is low.
The utility model is achieved in that a kind of corrugated stainless steel tubing votator, comprises combustion chamber and heat exchanger, and its special character is: described combustion chamber comprises cylindrical shell, top cover and bottom,
Have on the upper surface of described top cover on smoke interface, the lower surface and lead smoke pipe, a centre bore is arranged and on the described bottom around the wireway of centre bore;
Described heat exchanger is that the corrugated stainless steel tubing spiral twines the helix tube of making, and an end of corrugated stainless steel tubing constitutes the water inlet of helix tube, the delivery port that the other end constitutes helix tube;
Described wireway inserts the lower end of helix tube, leads the upper end that smoke pipe inserts helix tube; Gapped between helix tube and the cylindrical shell; The condensate draining mouth is arranged on the chassis between wireway and the cylindrical shell;
Also comprise a thermal insulation board, thermal insulation board is arranged in the helix tube.
Described a kind of corrugated stainless steel tubing votator, its special character is: described thermal insulation board is arranged on 3/4ths places of the height of helix tube.
Described a kind of corrugated stainless steel tubing votator, its special character is: described helix tube has two at least, and adjacent two helix tubes are fitted diametrically; The helix tube parallel connection.Thermal insulation board is positioned at the helix tube of radial center.
Described a kind of corrugated stainless steel tubing votator, its special character is: described thermal insulation board is arranged on 3/4ths places of height of the helix tube of radial center.
A kind of corrugated stainless steel tubing votator of the utility model, owing to adopt this spline structure, combustion gas is in the helix tube internal combustion of thermal insulation board bottom, to the helix tube inner chamber carry out 360 degree heating, the gap of waste heat between spiral visitor pitch enters between helix tube and the cylindrical shell, once more to spiral heating, enlarge the heat absorption area, improved the thermal efficiency; The band waste heat flue gas by in the helix tube that enters thermal insulation board top between helix tube and the cylindrical shell to the helix tube preheating; Flue gas is discharged by the smoke interface on the top cover.Owing to adopt the corrugated stainless steel tubing material to make heat exchanger, not only improved corrosion resistance, prolong the service life of heat exchanger, and increased endotherm area, improved heat absorption efficiency.The technical program has compared with prior art reduced parts, simplifies the structure, and has reduced cost.
