First by reference to the accompanying drawings specifically describe according to the air-returning pipe component of the utility model first aspect embodiment below.
As shown in Figure 1, according to air-returning pipe component of the present utility model, comprise muffler 10, capillary 20, corrosion-resistant coating 30 and fixed bed 40.Particularly, capillary 20 is set up in parallel with muffler 10, and corrosion-resistant coating 30 is located between capillary 20 and muffler 10, fixed bed 40 be set in muffler 10 with on capillary 20 so that muffler 10 is connected with capillary 20.
According to air-returning pipe component of the present utility model, by corrosion-resistant coating 30 being set between capillary 20 and muffler 10, can prevent from, between capillary 20 and muffler 10, electrolytic etching occurs, simultaneously, fixed bed 40 is set on muffler 10 and capillary 20 muffler 10 and capillary 20 is linked together, and makes to have between muffler 10 and capillary 20 efficiency of good return-air heat exchange.
According to an embodiment of the present utility model, muffler 10 is aluminum pipe.The price of aluminum pipe is relatively low, therefore, with aluminum pipe, replaces traditional Bandaid pipe or copper pipe, can significantly reduce the production cost of air-returning pipe component.
Further, according to an embodiment of the present utility model, corrosion-resistant coating 30 and fixed bed 40 are aluminum foil and adhesive tape layer.That is to say, muffler 10 is set in aluminum foil and adhesive tape layer with capillary 20, meanwhile, between muffler 10 and capillary 20, is aluminum foil and adhesive tape layer.Thus, with aluminum foil and adhesive tape layer, replace traditional thermal shrinkable sleeve, can simplify the production process of air-returning pipe component, enhance productivity.Meanwhile, aluminum foil and adhesive tape layer can not have influence on the return-air heat exchange efficiency between muffler 10 and capillary 20, has solved the poor problem of return-air heat exchange efficiency between muffler 10 that thermal shrinkable sleeve causes and capillary 20 of using.
It should be noted that, for aluminum foil and adhesive tape layer concrete mounting means on muffler 10 and capillary 20 and between the two, do not do particular restriction.Alternatively, the split of two-layer aluminum foil and adhesive tape layer is wrapped on air-returning pipe component, and two-layer aluminum foil and adhesive tape layer is separated from each other.Preferably, two-layer aluminum foil and adhesive tape one is wrapped on air-returning pipe component, in the preparation, first one deck aluminum foil and adhesive tape layer is wrapped between muffler 10 and capillary 20 and usings and use as corrosion-resistant coating 30, and then one deck aluminum foil and adhesive tape layer parcel is wrapped on capillary 20 and muffler 10 to form fixed bed 40.The structure that this one is wound around is more convenient in operation, can further reduce production process.
Because capillary 20 is general, adopt copper pipe, while therefore adopting the muffler 10 of aluminum pipe contact with capillary 20, copper aluminium electroloysis may occur between the two and corrode, and when muffler 10 and capillary 20 are when spaced apart, electrolytic etching effect disappears.Therefore, corrosion-resistant coating 30 prevents that the reason of electrolytic etching from being mainly because spaced apart muffler 10 does not directly contact both with capillary 20, thereby has avoided the generation of electrolytic etching.

Thus, corrosion-resistant coating 30 is spaced apart by capillary 20 and muffler 10, has avoided, between muffler 10 and capillary 20, electrolytic etching occurs.Meanwhile, because corrosion-resistant coating 30 is aluminum foil and adhesive tape layer, aluminum foil and adhesive tape layer has return-air heat exchange function, can be respectively and muffler 10 and capillary 20 return-air heat exchange.Therefore,, by the return-air heat exchange function of aluminum foil and adhesive tape layer, realized the return-air heat exchange between muffler 10 and capillary 20.
In addition, in another embodiment of the present utility model, corrosion-resistant coating 30 is set on the outer peripheral face of capillary 20.Thus, corrosion-resistant coating 30 all covers the outer peripheral face of capillary 20, and the muffler 10 being positioned at outside capillary 20 can directly not touch capillary 20, has avoided equally the generation of electrolytic etching.
Similarly, for making between muffler 10 and capillary 20 can return-air heat exchange, alternatively, according to an example of the present utility model, the internal perisporium laminating of the periphery wall of capillary 20 and corrosion-resistant coating 30, at least a portion laminating of the periphery wall of the periphery wall of corrosion-resistant coating 30 and muffler 10.Thus, corrosion-resistant coating 30 contacts with capillary 20 with muffler 10 respectively and carries out return-air heat exchange, further makes to carry out return-air heat exchange between muffler 10 and capillary 20.
Because corrosion-resistant coating 30 and fixed bed 40 are aluminum foil and adhesive tape layer, for the number of plies of aluminum foil and adhesive tape layer, do not do particular restriction, as long as meet aluminum foil and adhesive tape layer, there is respectively corrosion-resisting function and the requirement that is fixedly connected with effect.Alternatively, according to examples more of the present utility model, corrosion-resistant coating 30 and fixed bed 40 comprise respectively at least one deck aluminum foil and adhesive tape layer.
Thus, when corrosion-resistant coating 30 can play during for one deck aluminum foil and adhesive tape layer prevent muffler 10 and capillary 20 there are electrolytic etchings and make muffler 10 and capillary 20 between can return-air heat exchange effect, equally, when fixed bed 40 can play during for one deck aluminum foil and adhesive tape layer by muffler 10 and capillary 20 be fixed together can return-air heat exchange effect.When aluminum foil and adhesive tape layer is multilayer, this effect still exists.
