Description
Technical field
The utility model relates to a kind of coffee pot, relates in particular to the coffee pot pipe that is used for adding hot water in the coffee pot.
Background technology
The coffee pot pipe that is used for adding hot water in the existing coffee pot generally comprises calandria 1, heat-conducting metal layer 2, corrosion resistant heat-conductive water logical 3, described heat-conductive water logical 3 generally is installed in the inner surface of described heat-conducting metal layer 2, and the heat that receives calandria 1 by heat-conducting metal layer 2 is heated to suitable temperature to infuse coffee with the cold water in the heat-conductive water logical 3.As shown in Figure 1, that the coffee pot pipe of this structure needs to have between heat-conducting metal layer 2 and the heat-conductive water logical 3 is good, heat conduction fully is connected, obviously, heat-conducting metal layer 2 adopts common mode that the heat-conductive water in it logical 3 is wrapped up and can not meet the demands, because, both face contacts can not guarantee that complete, intact combination is arranged everywhere, and some exists the place in space just will inevitably have influence on the transmission efficiency and the speed of heat energy; Certainly, also can by adopt with stainless steel water logical make just can with the aluminium coating interference fit, the mode that pushes in the aluminium coating overcomes above-mentioned defective again, this solution needs comparatively accurate process equipment, simultaneously assembly technology also there is higher requirement, tends to make that the cost of manufactured goods rises.
In actual production, normally adopt welding manner to realize being connected between heat-conducting metal layer and the heat-conductive water logical 3, yet, because heat-conducting metal layer and heat-conductive water are that curved surface contacts between leading to 3, traditional welding manner such as welding powder weld, soldering paste welding or welding wire welding all can not reach abundant contact, the effect of quick conductive, reason is that welding powder welding and soldering paste welding only are applicable to that the welded article body is flat shape, when the welded article body is curved surface, when faying face spreads welding powder or soldering paste, it is many bottom surface welding powder or soldering paste to occur, and the side is waited non-uniform phenomenon less, like this, after the welding powder fusing, liquid solder flux since the effect of self gravitation to dirty, the bottom occur and weld, the non-uniform phenomenon of top inanition; And welding wire welding is not suitable for the welding between curved surface part especially, generally just is used for welding plane and the long part of weld seam, because the distance that the solder flux after the fusing relies on capillarity to extend is limited, is difficult to reach large tracts of land, the abundant purpose of welding.
Summary of the invention
The coffee pot pipe that provides a kind of heat transference efficiency higher is provided technical problem to be solved in the utility model.
According to the utility model, a kind of coffee pot pipe, comprise heat-conducting metal layer and the calandria that links together, is used for heating described heat-conducting metal layer with described heat-conducting metal layer, the inner surface of described heat-conducting metal layer has the corrosion resistant heat-conductive water of one deck logical, also be lined with one deck soldering lug between the outer surface that the inner surface of described heat-conducting metal layer and described heat-conductive water lead to, described heat-conducting metal layer and described heat-conductive water are crossed described soldering lug all and are welded to connect.
After adopting the utility model, because the outer surface that leads at the inner surface of heat-conducting metal layer and corrosion resistant heat-conductive water is welded to connect by one deck soldering lug of liner, utilize soldering lug self uniform in shaping, thickness to make that heat-conducting metal layer and heat-conductive water being welded to connect between leading to is very even, full, abundant, complete according to arbitrarily selected and brazing material the in advance hot melt of actual needs, thereby, there is good heat conduction to be connected between heat-conducting metal layer and heat-conductive water are logical, improve heat transfer efficiency, and on manufacture craft, also do not needed too high precision.
The purpose of this utility model, feature and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
Description of drawings
Fig. 1 is the structural representation of existing coffee pot pipe;
Fig. 2 is the structural representation of a kind of coffee pot pipe of the utility model;
Fig. 3 be along A-A shown in Figure 2 to cross-sectional view;
Fig. 4 is that heat-conducting metal layer and heat-conductive water lead to structural representation in forming process among a kind of embodiment of a kind of coffee pot pipe of the utility model.
Concrete embodiment
With reference to Fig. 2 and Fig. 3, a kind of coffee pot pipe, comprise heat-conducting metal layer 2 and the calandria 1 that links together, is used for heating described heat-conducting metal layer 2 with described heat-conducting metal layer 2, the inner surface of described heat-conducting metal layer 2 has the corrosion resistant heat-conductive water of one deck logical 3, also be lined with one deck soldering lug 4 between the outer surface of the inner surface of described heat-conducting metal layer 2 and described heat-conductive water logical 3, described heat-conducting metal layer 2 and described heat-conductive water logical 3 are welded to connect by described soldering lug 4.
The setting of calandria 1 just is used for heating by 2 pairs of heat-conductive waters of heat-conducting metal layer logical 3, therefore, make the material of heat-conducting metal layer 2, the concrete shape of calandria 1 and the connected mode of calandria 1 and heat-conducting metal layer 2, can have a variety of, need not give unnecessary details, as long as can Fast Heating, fully heat conduction.
Described heat-conducting metal layer 2 can be assuring that aluminum is assured or other heat conductivility preferred metal materials are made, and it is not only light to use metallic aluminium to make, and cost is not high yet.
Described corrosion resistant heat-conductive water logical 3 is logical for stainless steel water, using stainless purpose is to utilize the good anti-corrosion of this material own, obviously, has similarity, be that heat conduction is good, the heat-conductive water that the other materials that corrosion resistance is strong is made is logical equally can to reach the purpose of this utility model.
In fact, in manufacturing process of the present utility model, described soldering lug 4 can be the sial weld tabs, as shown in Figure 4, before heat-conducting metal layer 2 (assuring) moulding as aluminum with described soldering lug 4, as the sial weld tabs, liner is at described heat-conducting metal layer 2 inner surfaces in advance, the heat-conducting metal layer 2 of shown tubulose is can right and wrong enclosed, this structure can be so that manufacture craft of the present utility model be more simple, because after adopting such design, for heat-conducting metal layer 2 (assuring) as aluminum, heat-conductive water logical 3 all need not accurate process equipment and machining accuracy, logical 3 o'clock of heat-conductive water is installed also need not complicated technology, utilize soldering lug self uniform in shaping, thickness can make that heat-conducting metal layer and heat-conductive water being welded to connect between leading to is very even according to actual needs hot melt in advance arbitrarily selected and brazing material, full, fully, complete, thus heat conduction efficiency can be improved.
