Technical field
The utility model relates to the evaporimeter in a kind of air conditioner, particularly a kind of parallel-flow evaporator that is used for domestic air conditioning.
Background technology
Parallel-flow evaporator is used more on automotive air conditioning device, but belongs to a kind of novel application on family expenses air-conditioning (as cabinet-type air conditioner).This evaporimeter mainly is made up of liquid trap, flat tube, fin, input pipe and efferent duct.Take welding manner between its fin and the flat heat exchange pipe, belong to contact fully, compare with the copper tube and fin formula evaporimeter that existing cabinet-type air conditioner is used always, it is high that heat exchange efficiency is wanted, owing to mainly adopt aluminium, cost is relatively low simultaneously.But present parallel-flow evaporator mostly is single row configuration greatly, the cabinet-type air conditioner that the heat exchanging Capability Requirement is higher, and single parallel-flow evaporator can not meet the demands.Chinese patent application 200610020533.1 discloses a kind of vehicle air-conditioning device double layer thin type parallel-flow evaporator, and front evaporator device and finisher is combined, and promptly two-layer parallel-flow evaporator is integrated, and improves heat exchange efficiency, reaches purpose of energy saving.Specification according to Chinese patent application 200610020533.1 is described as can be known, because its refrigerant at first enters finisher by inlet tube, enter the front evaporator device by finisher then, flow out by outlet at last, therefore it comes down to be made of two parallel-flow evaporator series connection, and effective throttling arrangement is not set, and therefore also fail effectively to improve the refrigerating capacity of evaporimeter, therefore the double-deck parallel-flow evaporator of this structure can not satisfy the requirement of domestic air conditioning (particularly cabinet-type air conditioner).
Summary of the invention
The technical problems to be solved in the utility model is to overcome the shortcoming of above-mentioned prior art, a kind of heat exchange efficiency height is provided, is applicable to the parallel-flow evaporator of the domestic air conditioning of high heat exchange requirement.
The realization the technical solution of the utility model is: a kind of parallel-flow evaporator, be connected in the refrigerating circuit of domestic air conditioner by input house steward and delivery trunk, it comprises at least two independently evaporator assemblies, the all evaporators assembly is superimposed together, and their input pipe is connected with the input house steward by same current divider; The efferent duct of all evaporators assembly all is connected with delivery trunk by another current divider.
Be equipped with capillary on the input pipe of described evaporator assemblies.
Be equipped with many inlet branch on described each evaporator assemblies.
Link to each other by same current divider between described inlet branch and the input pipe.
Described inlet branch is provided with arm shunting capillary.
As further improvement of the utility model, in the described two adjacent arbitrarily evaporator assemblies, the planar dimension of upper strata evaporator assemblies is greater than or less than the planar dimension of lower floor's evaporator assemblies.
The width unanimity of all evaporators assembly, length shortens successively according to superimposed order from the bottom to top.
The last liquid trap alignment of all evaporators assembly or the following liquid trap alignment of all evaporators assembly, and interfix.
Described evaporator assemblies comprises evaporimeter and following evaporimeter, and the planar dimension of following evaporimeter is greater than the planar dimension of last evaporimeter.Specifically, the width of described last evaporimeter is consistent with following evaporimeter, and length is half of following evaporimeter, and the last liquid trap alignment of upper and lower evaporimeter also interfixes.
Novel parallel flow evaporator device provided by the utility model, a plurality of parallel-flow evaporator assemblies are connected in parallel with input house steward and delivery trunk by current divider, on each input pipe, input house steward and inlet branch, capillary is set simultaneously, further improved the heat exchange efficiency of evaporimeter, satisfy the requirement of the domestic air conditioning of high heat exchange requirement, particularly each evaporator assemblies is adopted the structural design of different length size, can reach the optimum balance of cost and efficiency aspect.
Description of drawings
Fig. 1 is the structural representation of the utility model parallel-flow evaporator embodiment;
Fig. 2 is the left side schematic diagram of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model parallel-flow evaporator is described further.As accompanying drawing 1, shown in 2, parallel-flow evaporator in the present embodiment comprises existing individual layer parallel-flow evaporator (being said evaporator assemblies in the utility model: go up evaporimeter 2 and following evaporimeter 4) the necessary member of operate as normal, its main improvement is last evaporimeter 2 and following evaporimeter 4 are connected in parallel, wherein descend evaporimeter 4 sizes can with existing individual layer parallel-flow evaporator consistent size, the width of last evaporimeter 2 is identical with following evaporimeter 4, its length dimension is 1/2nd of following evaporimeter 4, on, following evaporimeter 2,4 last liquid trap 1,1a alignment, and the use that is superimposed.Last evaporimeter 2 is provided with an efferent duct 14, also is provided with an efferent duct 13 on the following evaporimeter 4, and efferent duct 14,13 is connected with delivery trunk 16 by distributing T-pipe device 12.Following evaporimeter 4 is provided with 3～8 inlet branch 5, it is the same with inlet branch 5 on the following evaporimeter 4 that the inlet branch 5a quantity of last evaporimeter 2 can be selected, also can be different, about the implementation case, the inlet branch 5 of evaporimeter 2,4,5a quantity be the same, is 4 input pipes.
In the present embodiment, input house steward 15 is through 9 shuntings of brass current divider, and evaporimeter input pipe 8 reaches and goes up evaporimeter input pipe 10 under inserting, and upper and lower evaporimeter input pipe 10,8 respectively is connected to a shunting capillary 11,11a; Following evaporimeter input pipe 8 connects a brass current divider 7 (this brass current divider 7 is selected corresponding specification according to the quantity of inlet branch 5) again, in the present embodiment, tell four road pipelines by brass current divider 7, be connected with following evaporimeter inlet branch 5 more respectively with after arm shunting capillary 6 links to each other.Equally, the inlet branch 5a of last evaporimeter 2 connects in the same way.
As shown in Figure 1, evaporimeter all has brass current divider 7, arm shunting capillary 6, inlet branch 5 up and down, is convenient expression, only does sign at the following corresponding parts of evaporimeter; Arm shunting capillary 6, capillary 11,11a only are schematic diagram, actual size be not on the figure shown in.
Refrigerant flows into evaporimeter input pipe 10, following evaporimeter input pipe 8 through input house steward 15 respectively from brass current divider 9, after evaporimeter brass distributor 7 is separately shunted up and down, enter the flat tube of parallel-flow evaporator assembly through inlet branch 4, evaporation heat absorption in flat tube, respectively from last evaporator output tube 14 and evaporator output tube 13 outflows down, converge to delivery trunk 16 then by distributing T-pipe device 12.Upper and lower evaporimeter 2,4 selects different length dimensions to compare with the structure of selecting same size for use, can save cost, but its heat exchange effect can reach basically identical.Particularly on the following liquid trap 3a, 3 of upper and lower evaporimeter 2,4, connect respectively by many inlet branch 5a, 5 and arm shunting capillary 6, the refrigerant that makes parallel-flow evaporator get input has carried out repeatedly effectively shunting and has quickened, and has improved its heat exchange efficiency greatly.
