Abstract
The invention discloses a gas and liquid heat exchanger which comprises a heat exchanger pipe body that is integrally formed by a heat absorbing sheet and a water passing pipeline, wherein, an upper end cover and a lower end cover are respectively fixedly arranged at the both ends of the heat exchanger pipe body; channels are opened on the surfaces of the upper end cover and the lower end cover which are matched with the heat exchanger pipe body; the channels on the upper end cover and the lower end cover, and the water passing pipeline on the heat exchanger pipe body are communicated to form a waterway. A water inlet pipe and a water outlet pipe are arranged on the channels on the upper end cover or the lower end cover; as the upper end cover, the lower end cover and the heat exchanger pipe body adopt a screw for connection, the water pipeline does not need to be welded, thereby ensuring good appearance; aluminum materials with very strong anti-corrosion capability is adopted, so paint is not need to be coated; the heat absorbing sheet and the water pipeline are integrally formed, thereby having better heat transfer effect and more simple processing technology. Therefore, the gas and liquid heat exchanger can be widely applied to gas and liquid heat exchange on gas water heaters.
Description
Technical field
The present invention relates to the heat exchanger between a kind of gas and the liquid, is the heat reclaim unit to gas heater flue gas and other field high-temperature gas specifically.
Background technology
Heat exchanger all is installed at present, so that water or air are heated on gas heater.Especially for the on-condensing gas heater, because flue-gas temperature is up to 250～270 ℃, take away sizable a part of heat, cause energy waste, for utilizing this part heat of being taken away by flue gas as far as possible, people set up a cover secondary heat exchanging system on gas heater, normally adopt " fin+pipe " formula structure.Though acidic gas in flue gas does not produce corrosion to any metal material when gaseous state, but when flue-gas temperature drops to certain value, water vapour in the flue gas can condense into water, acidic gas in flue gas is met water and is then generated acid, acid meeting heavy corrosion copper material, for this reason, the method that now can adopt is: 1, be coated with one deck anti-corrosion material on the surface that contacts with flue gas or condensed water on the copper heat exchanger; 2, make copper material into aluminium, because of aluminium material surface can generate layer oxide film, this oxide-film can prevent that material further is corroded.More than two kinds of methods separately shortcoming is all arranged.The welding procedure of aluminum pipe is immature, is easy to generate weld defect or outward appearance is ugly, thereby seldom is used.The scheme that the copper material surface is coated with anti-corrosion material has the acid corrosion-resistant except requiring anti-corrosion material, also requiring can be high temperature resistant, have good adhesive, coating can cover the copper material all surface that may touch condensed water fully between coating and the copper material, coating layer thickness can not too greatly can not be too little, because of coating material is poor conductor, too thick meeting influence the heat exchange effect, too thinly be not easy to cover all surface, can satisfy above the requirement simultaneously and be actually very difficult.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides that a kind of technology is simple, the thermal efficiency is high, the heat exchanger of long service life.
The technical solution adopted for the present invention to solve the technical problems is:
The heat exchanger of a kind of gas and liquid, comprise the integrated heat exchanger tube of heat absorbing sheet and ventilating water pipe, the two ends of heat exchanger tube are installed with upper end cover and bottom end cover respectively, the face that upper end cover and bottom end cover cooperate with heat exchanger tube has raceway groove, and the raceway groove on upper end cover and the bottom end cover communicates with ventilating water pipe on the heat exchanger tube and forms the water route.The raceway groove of described upper end cover or bottom end cover is provided with water inlet pipe and outlet pipe;
As improvement of the technical scheme, the heat absorbing sheet of described heat exchanger tube is arranged on the outside or the inboard of ventilating water pipe;
As further improvement in the technical proposal, be provided with sealing gasket between described raceway groove and the ventilating water pipe; Described heat absorbing sheet vertically is arranged on the ventilating water pipe;
The invention has the beneficial effects as follows: because upper and lower end cap and heat exchanger tube adopt screw attachment, water lines need not welded, and can guarantee good surface appearance; Material adopts has very strong antiseptic power aluminium, thereby does not need coating; Heat absorbing sheet and water lines are one-body molded, and heat-transfer effect is better, processing technology is simpler.Thereby can be widely used in the heat exchange of gas and liquid on the gas heater.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of second kind of embodiment of the present invention.
The specific embodiment
With reference to Fig. 1; Fig. 2; the heat exchanger of a kind of gas and liquid; it comprises heat absorbing sheet 11 and ventilating water pipe 12 integrated heat exchanger tube 1; described heat exchanger tube 1 is made as square according to actual needs; arbitrary shapes such as circle; the two ends of heat exchanger tube 1 adopt bolting that upper end cover 2 and bottom end cover 3 are installed respectively; the face that upper end cover 2 and bottom end cover 3 cooperate with heat exchanger tube 1 has raceway groove 4; raceway groove 4 on upper end cover 2 and the bottom end cover 3 communicates with ventilating water pipe 12 on the heat exchanger tube 1 and forms the water route; the raceway groove 4 of described upper end cover 2 or bottom end cover 3 is provided with water inlet pipe 5 and outlet pipe 6; the water route form that the present invention forms is diversified; as: through type; formula etc. back and forth; so long as realize purpose of the present invention, all belong to protection scope of the present invention in a word with essentially identical means.
The operation principle of this product is: when the flue gas of high temperature enters, cold water enters in the ventilating water pipe 12 from water inlet pipe 5, because heat absorbing sheet 11 vertically is arranged on the ventilating water pipe 12, so cold water absorbs high-temperature flue gas heat preheating current, the while cooled flue gas, cooled smoke is discharged outdoor, because this product adopts the extrusion modling of corrosion resistant aluminium one, and the raceway groove 4 that adopts upper end cover 2 and bottom end cover 3 communicates with ventilating water pipe 12 and forms the water route, thereby need not weld, so make very easy, long service life.
The present invention can be provided with sealing gasket by described raceway groove 4 in order to make heat exchanger tube 1 better with upper end cover 2 and bottom end cover 3 sealing effectiveness.In addition, the heat exchanger tube 1 that this product uses can vertically be arranged on heat absorbing sheet 11 outside or the inboard of ventilating water pipe 12 according to client's actual needs, because the heat utilization efficiency of this product greatly improves.Thereby can be widely used in the heat exchange of gas and liquid on the gas heater.
