Abstract
The utility model discloses a condensing type heat exchanger for a gas combustion water heater, which comprises a plurality of heat exchanging pipes, a plurality of heat absorbing sheets and a plurality of prerotation vanes, wherein the prerotation vanes are arranged in the heat exchanging pipes, and the heat exchanging pipes are sleeved in the heat absorbing sheets. The utility model has the advantages that the water resistance is small, the flow capacity is big, the heating efficiency is high, smoke gas which is generated by the condensing type heat exchanger can be branched and rapidly discharged, the cost performance is high, the structure and the manufacturing are comparatively simpler, and the heat exchanger is suitable for the gas combustion water heater and a wall-mounted boiler in the market.
Description
Technical field
The utility model relates to a kind of heat exchanger, especially a kind of gas heater condensed heat exchanger.
Background technology
The tradition gas heater is equipped with related devices such as combustion chamber, heat exchanger usually, utilize heat exchanger to absorb the energy that combustion gas produced, pass to by the flow through cold water of heat exchanger of water inlet pipe, water temperature raises after heat exchange, hot water is discharged from outlet pipe, realize the function of flow heated water, the high-temperature flue gas that burning produces is extracted out outdoor by blower fan through the tobacco pipe chamber.Because flue gas is taken away sizable part energy, causes the thermal efficiency of water heater limited, heat utilization ratio is difficult to promote.People set up a cover flue gas condensing system on the heat exchanger basis of traditional gas heater for this reason, the combustion chamber is by the combustion gas heating heat exchanger, produce high-temperature flue gas, be drawn into smoke chamber through blower fan, cold water enters condenser from water inlet pipe and absorbs the high-temperature flue gas heat preheating current that produce the combustion chamber, and cooled flue gas is separated out condensed water and inorganic salt simultaneously, condensed type combustion gas water heater has utilized the flue gas heat flow heated water, and heat utilization efficiency is greatly improved.
Present condensation ability of swimming heat exchanger all is to utilize single tube to carry out heat exchange, have big water resistance like this, and flow seldom, " a kind of gas heater condensed heat exchanger " disclosed as Chinese patent 200520053505.0, though this heat exchanger thermal efficiency is significantly improved than many heat exchangers, but the problem that the single tube exchange exists is still unresolved, and uses pipe to do heat-exchange tube, and the thermal efficiency is still lower.
The utility model content
The flue gas shunting that the purpose of this utility model is to provide that a kind of water resistance is little, flow is big, the thermal efficiency is high, can produce condensed heat exchanger and discharging fast, and cost performance height, structure and make better simply relatively gas heater condensed heat exchanger.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of gas heater condensed heat exchanger comprises a plurality of heat-exchange tubes, polylith heat absorbing sheet and polylith flow deflector, and flow deflector places heat-exchange tube, and heat-exchange tube is enclosed within the heat absorbing sheet.
Described heat-exchange tube is an elliptical tube.
Described heat absorbing sheet is a base material with copper-nickel alloy or red copper, and its surface is coated with the corrosion resistant plated film of one deck, is provided with a flue gas shunting sheet in the centre of polylith heat absorbing sheet, and this flue gas shunting sheet bottom is provided with flue gas water conservancy diversion conduit.
The utlity model has following beneficial effect:
(1) utilizes multitube to carry out heat exchange, reduced water resistance effectively, increased the flow of water.
(2) heat-exchange tube has adopted elliptical tube, and more traditional round tube endotherm area is big, thereby has improved the thermal efficiency effectively.
(3) flow deflector places heat-exchange tube, current is played the effect of water conservancy diversion shunting.
(4) shape of heat absorbing sheet and flue gas shunting sheet are suitable for flue gas shunting and discharge, and simultaneously flue gas shunting sheet bottom is provided with flue gas water conservancy diversion conduit, to strengthen flue gas guide functions fast.
(5) heat absorbing sheet is a base material with copper-nickel alloy or red copper, and it is good, fine and close, even, smooth that the surface is coated with one deck character, particularly to the corrosion resistant plated film of flue gas condensing liquid, not only effectively improves the decay resistance of heat exchanger, also strengthened the heat transfer property of heat exchanger.
(6) the utility model compact conformation is reasonable, makes simplyr relatively, is applicable to gas heater and wall-hung boiler on the market.
