Abstract
The utility model discloses a kind of refrigerator evaporator, comprise capillary, aluminum pipe, the arrival end of this aluminum pipe is tapered configuration, and termination is directly welded with this capillary one end.The utility model is by the connected mode of conventional capillary through reducing copper sleeve and aluminum pipe, and be improved to and be set to tapered configuration by one of aluminum pipe link section, entrance termination is directly connected with capillary, eliminates reducing copper sleeve equipment, decreases pad simultaneously; In addition by aluminum pipe outlet extending, be directly connected with compressor, eliminate the copper sleeve at traditional structure middle outlet place, and the pad of correspondence, whole evaporimeter slip is low, and product quality is high, long service life.
Description
Technical field
The utility model relates to technical field of refrigeration equipment, especially a kind of refrigerator evaporator.
Background technology
Refrigerator uses very general in existing life, and there is use in the supermarket as various scale, is convenient to refrigerate various food.Evaporimeter is one of vitals of refrigerator, and Main Function absorbs foodstuff calories in refrigerator exactly, and carries out fast cooling to food, reaches the effect of fresh-keeping anti-metamorphic.
And existing refrigerator evaporator is capillary is mostly connected through reducing copper sleeve with expansion tube, the cold-producing medium of compression is sprayed to expansion tube by capillary; The muffler of cold-producing medium after heat absorption again through being connected with the copper sleeve at evaporator outlet place, returns compressor; In order to be connected firmly, all will weld in the both sides of the copper sleeve at aluminum pipe entrance and exit two place, but due to the bad control of two places welding operation, often leak, disqualification rate is high, affects product quality and service life.
Utility model content
The utility model is for the deficiencies in the prior art, and propose a kind of refrigerator evaporator, structure is ingenious, and slip is low.
In order to realize above-mentioned utility model object, the utility model provides following technical scheme: a kind of refrigerator evaporator, comprises capillary, aluminum pipe, and the arrival end of this aluminum pipe is tapered configuration, and termination is directly welded with this capillary one end.
Further, the converging transition length of this aluminum pipe is 80 ~ 90mm.
Further, the termination internal diameter of this converging transition is identical with capillary inner diameter.
Further, the port of export of this aluminum pipe extends to and is directly connected with compressor.
Compared with prior art, the utility model has the following advantages: by the connected mode of conventional capillary through reducing copper sleeve and aluminum pipe, be improved to and be set to tapered configuration by one of aluminum pipe link section, entrance termination is directly connected with capillary, eliminate reducing copper sleeve equipment, decrease pad simultaneously; In addition by aluminum pipe outlet extending, be directly connected with compressor, eliminate the copper sleeve at traditional structure middle outlet place, and the pad of correspondence, whole evaporimeter slip is low, and product quality is high, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model refrigerator evaporator;
Fig. 2 is Fig. 1 broken section enlarged drawing.
Detailed description of the invention
Be described in detail the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
As illustrated in fig. 1 and 2, the periphery of refrigerator 1 is coated with the aluminum pipe 2 of evaporation, and the arrival end 21 of aluminum pipe 2 is tapered configuration, and termination is directly welded with capillary 3 one end.Be high-pressure refrigerant in capillary 3, its internal diameter, much smaller than aluminum pipe 2 internal diameter, expands in aluminum pipe 2, reaches food cooling object in refrigerator 1.
As shown in Figure 2, its most path is identical with capillary 3, and both can directly weld like this, do not need reducing copper sleeve to connect for arrival end 21 tapered configuration of aluminum pipe 2; This converging transition 211 length L suitable length is 80 ~ 90mm, can reduce noise, improves the service life of product.
At the port of export 22 place of aluminum pipe 2, the aluminum pipe of the port of export 22 is carried out prolongation process, be directly connected with compressor until aluminum pipe 2 exports termination, which reduce the connector of conventional evaporator and corresponding pad.
The utility model product, compared with traditional product, eliminates the copper sleeve that two places imported and exported by aluminum pipe 2, has saved cost, also reduce the pad on traditional copper joint simultaneously, correspondingly decreases leakage phenomenon, improves the quality of product, extends service life.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent implementations of doing of spirit or change all should be included within protection domain of the present utility model.
Claims (4)
1. a refrigerator evaporator, comprises capillary, aluminum pipe, it is characterized in that: the arrival end of this aluminum pipe is tapered configuration, and termination is directly welded with this capillary one end.
2. refrigerator evaporator as claimed in claim 1, is characterized in that: the converging transition length of this aluminum pipe is 80 ~ 90mm.
