In an embodiment of the present utility model, the bottom surface of housing 210 is inclined upwardly to the centre from the left and right sides.Certainly, the utility model is not limited to this, and in another embodiment of the present utility model, the bottom surface of housing 210 from left to right tilts from the top down.And in another embodiment of the present utility model, the bottom surface of housing 210 from left to right tilts from top to bottom.Wherein, preferably, the range of tilt angles of the bottom surface of housing 210 is the 1-45 degree.
Thus, make condensed waters in heat exchanger 200 can more easily flow in the condensation water collection dish 300 of its below and be discharged from outside water heater.
According to preferred embodiment of the utility model, the inner chamber cross section of leading smoke pipe 212 forms ellipse.That is to say, lead in smoke pipe 212 and be formed with slotted eye, like this, when making high-temperature flue gas flow within it, resistance is less, can make thus heat exchange efficiency higher.
As shown in Figure 1, heat exchanger 200 can further comprise silicagel pad 250, and silicagel pad 250 is located between cover plate 220 and housing 210 with seal cover board 220 and housing 210.By between cover plate 220 and housing 210, silicagel pad 250 being set, formed the sealing between cover plate 220 and housing 210, and omitted the welding sequence that in the tradition, welding heat-exchanger is sealed, and manufacturing being simple and cost is low.
In a preferred embodiment of the present utility model, heat exchanger 200 also can comprise a plurality of guiding gutters, guiding gutter is arranged and is limited by a plurality of deflectors 260 intervals, a plurality of guiding gutters interval is arranged in heat exchange chamber 211 to form roundabout water channel, can make like this water flow energy along roundabout water channel flow and with on the way lead smoke pipe 212 heat exchange, improve the space availability ratio of heat exchange chamber 211, increased heat exchange area and the heat-exchange time of current, improved the heat exchange efficiency of heat exchanger 200.
Alternatively, housing 210, lead smoke pipe 212 and guiding gutter cast molding integratedly.Particularly, heat exchanger 200 can step as shown in Figure 5 be made.
S1, first curved good water inlet pipe 230 and outlet pipe 240;
S2 puts into housing mould to water inlet pipe 230 and outlet pipe 240 and carries out the high temperature cast;
S3 is with the disposable high temperature cast of cover plate 220;
S4 carries out respectively blasting treatment to housing 210 and cover plate 220;
S5 carries out preservative treatment with the surface of housing 210 and the sidewall of heat exchange chamber 211;
S6 is threaded connection housing 210 and cover plate 220 and for example adopts bolt to install, and wherein silicagel pad 250 is assemblied between housing 210 and cover plate 220 so that housing 210 and cover plate 220 are sealed.
Wherein, the material of heat exchanger 200 can adopt copper, aluminium, cast iron and stainless steel etc.
Thus, according to heat exchanger of the present utility model, omit traditional a plurality of welding sequences, reduced producing cost, and can also solve the problem that traditional coil pipe and case shell leak.
As shown in Figure 1, in embodiment more of the present utility model, adopt the heat exchanger of gas heater of the present utility model also further to comprise flue gas spoiler 600, flue gas spoiler 600 is located at the time of staying with prolong smoke in exhaust air chamber 400 within it.
Particularly, flue gas spoiler 600 comprises plate body 610 and installing plate 620, is formed with a plurality of passages 611 to be passed through by the waste gas of discharging in heat exchanger 200 on plate body 610.Installing plate 620 extends upward and is suitable for being connected with the inwall of exhaust air chamber 400 from the limit, the left and right sides of plate body 610, as shown in Figure 6.Like this, by at the interior flue gas spoiler 600 that arranges of exhaust air chamber 400, the time that makes flue gas stay in exhaust air chamber 400, can make thus heat to remain on more and for more time in heat exchanger 200 so that water is heated, further improved heat exchange efficiency, save simultaneously a large amount of energy resource consumptions, reduced widely production cost.Preferably, a plurality of passages 611 on plate body 610 are arranged equably according to many rows multiple row or a plurality of concentric circles.
In further embodiment of the present utility model, as shown in Figure 1, gas heater also comprises drip pipe 310, and drip pipe 310 is communicated with that with condensation water collection dish 300 condensed water in condensation water collection dish 300 is discharged.
In addition, according to some embodiment of the utility model, adopt the following combustion chamber 100 that arranges in gas heater.As Fig. 8-shown in Figure 10, combustion chamber 100 comprises ceramic fibre spare 110 and electrolysis flaggy 120, and ceramic fibre spare 110 inside limit combustion chamber.Electrolysis flaggy 120 is located at the outside of ceramic fibre spare 110.That is to say, combustion chamber 100 comprises materials at two layers, and skin is electrolytic zinc-coated steel sheet 120, and internal layer is made by ceramic fibre material.Wherein, the ceramic fibre material that internal layer adopts is nontoxic, and high temperature resistant (reaching 1700 ℃) avoided combustion gas to burn out the sidewall of combustion chamber.And outer make of electrolytic zinc-coated steel sheet, its performance does not affect the hot water efficient of water heater, at the bottom of can not causing water heater, the face-piece surface temperature is too high yet.
Thus, by combustion chamber 100 being arranged to comprise ceramic fibre spare 110 and the outer field electrolysis flaggy 120 of internal layer, avoided the poor defective of heat transfer property in the conventional water heaters, in the use procedure of water heater, reduced the possibility that the too high and combustion gas of the skin temperature of water heater burns out the combustion chamber, good heat-transfer.
According to an example of the present utility model, electrolysis flaggy 120 sticks on skin and the bottom of ceramic fibre spare 110 and extends downwards for fixing installation portion 130.Alternatively, two installation portions 130 respectively from the electrolysis flaggy 120 on left side and right side to downward-extension, and be formed with at least two installing holes 131 on each installation portion 130 to be used for the install combustion chamber.
Thus, adopt the gas heater according to heat exchanger of the present utility model, simple in structure, easy to operate and low cost of manufacture.
Other configuration examples as for gas heater are all known as exhaust air chamber 400 and fan assembly 500 etc. and operation for those of ordinary skills, are not described in detail here.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiment or example.
