The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of simple in structure, easy for installation, can control the evaporimeter usable floor area according to the required refrigerating capacity of refrigerator, the layout structure of the refrigerator evaporator fin of energy efficient.
The layout structure of a kind of refrigerator evaporator fin that the utility model provides; Comprise the refrigerating circuit that constitutes by compressor, condenser, evaporimeter; Be provided with reservoir between compressor and the evaporimeter, be provided with device for drying and filtering between condenser and the evaporimeter, said evaporimeter by be in parallel main evaporator, secondary evaporimeter constitute; Main evaporator, secondary evaporimeter are connected on the magnetic valve through capillary respectively, and the said magnetic valve other end is connected with device for drying and filtering in the refrigerating circuit.
Wherein, Major and minor evaporimeter includes refrigeration pipe, the fin of range upon range of bending and is installed in the end plate of both sides; Offer through hole on said fin and the end plate; Refrigeration pipe interconnects fin and end plate through through hole, and main evaporator, secondary evaporimeter are connected through the fixture that is provided with on the end plate of two ends.
Wherein, main evaporator and secondary evaporimeter are layout up and down, and the area of secondary evaporimeter is the 30%-100% of main evaporator area.
Preferably, the area of said secondary evaporimeter is the 50%-75% of main evaporator area.
Wherein, main evaporator fin spacing distance is 5-12mm, and secondary evaporator fin spacing is 10-30mm.
Preferably, main evaporator fin spacing distance is for being 6-8mm, and secondary evaporator fin spacing is 18-24mm.
Wherein, the fin of the fin of secondary evaporimeter and main evaporator side by side or be crisscross arranged.
Preferably, the both sides, bottom of said fin all slope inwardly.
The utility model can realize that the opening of major and minor evaporimeter that is in parallel close through solenoid control, according to refrigerator the demand of refrigerating capacity is decided the utilization and operation of major and minor evaporimeter, thereby has reduced the energy consumption of compressor, has realized the refrigerator energy-saving effect.And the structural design of major and minor evaporimeter not only guaranteed the unobstructed of airflow, and its drainability also is improved.

Fig. 3 is the structural representation of the main evaporator of the utility model, the staggered joint of secondary evaporimeter.
The specific embodiment
Referring to Fig. 1; The layout structure of the refrigerator evaporator fin that the utility model provides comprises the refrigerating circuit that is made up of compressor 1, condenser 2, evaporimeter 3; Be provided with reservoir 4 between compressor 1 and the evaporimeter 3; Be provided with device for drying and filtering 5 between condenser 2 and the evaporimeter 3; Said evaporimeter 3 by be in parallel main evaporator 6, secondary evaporimeter 7 constitute, main evaporator 6, secondary evaporimeter 7 are connected on the magnetic valve 9 through capillary 8 respectively, said magnetic valve 9 other ends are connected with device for drying and filtering 5 in the refrigerating circuit.
During operation; The high-temperature high-pressure refrigerant gas that compressor 1 is discharged becomes the liquid of cryogenic high pressure through condenser 2 coolings, and process device for drying and filtering 5 backs are by magnetic valve 9 shuntings; One the tunnel through capillary entering main evaporator 6; Another road gets into secondary evaporimeter 7 through another capillary, compile again at last get into reservoir 4 after, get back to compressor 1.
When refrigerator needed big cold, magnetic valve 9 was opened two groups of evaporimeters simultaneously, and system is the refrigerator refrigeration fast.When refrigerator only needed less refrigerating capacity, only opened main evaporator 6 this moment, closes secondary evaporimeter 7, makes the less refrigerant flow of system held, reduces the energy consumption of compressor.Thereby realize giving the effect of refrigerator energy-saving.
Present embodiment is main evaporator 6 among the embodiment 1, secondary evaporimeter 7 parallel-connection structure compound modes.Referring to Fig. 2; Major and minor evaporimeter includes refrigeration pipe 10, the fin 11 of range upon range of bending and is installed in the end plate 12 of both sides; Offer through hole on said fin 11 and the end plate 12; Refrigeration pipe 10 interconnects fin 11 and end plate 12 through through hole, and main evaporator 6, secondary evaporimeter 7 are linked up with 13 phase clampings through the U type that is provided with on the two ends end plate 12, and main evaporator 6 and secondary evaporimeter 7 are up and down to be arranged.
The area of secondary evaporimeter 7 is the 30%-100% of main evaporator 6 areas, more preferably at 50%-75%.Wherein main evaporator 6 fin spacing distances are less, and spacing is 5-12mm, more preferably can be 6-8mm.Secondary evaporimeter 7 inter fin spaces are bigger, and spacing can be 10-30mm, more preferably is 18-24mm.The fin of secondary evaporimeter 7 can be arranged side by side with main evaporator 6 when being provided with, but better can with main evaporator 6 fin interlaced arrangement, the fin of promptly secondary evaporimeter 7 is arranged in the centre of two main evaporator 6 fin that are adjacent.The interior wind of case flows from secondary evaporimeter 7 belows vertically upward during refrigeration; Wind flows through between secondary evaporimeter 7 adjacent two fin; Above will getting between the main evaporator fin during air channel, be divided into the some strands of Parallel airflows main evaporator of flowing through by the top fin, help the circulation of air.
During operation, cold-producing medium flows in the refrigeration pipe of main evaporator 6 and secondary evaporimeter 7 simultaneously, and flows out from two groups of evaporimeters respectively.
Present embodiment is the structural representation of main evaporator 6 among the embodiment 2, secondary evaporimeter 7 staggered joints.Referring to Fig. 3; The fin of said secondary evaporimeter 7 is arranged in the centre of two main evaporator 6 fin that are adjacent; The both sides, bottom of said fin all slope inwardly, and the defrost water 14 of fin can fall in minimum point along the angle of inclination below the fin in the drippage toward below under the gravity effect like this, directly fall in the water-collecting tray of evaporimeter below; The defrost water droplet of having avoided main evaporator prevents that ponding freezes on the secondary evaporimeter on the evaporation tube or fin of secondary evaporimeter.
