Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy for installation, can control evaporimeter usable floor area according to the required refrigerating capacity of refrigerator, save the layout structure of the fin evaporator for refrigerator of energy consumption.
The layout structure of a kind of fin evaporator for refrigerator provided by the invention, comprise by compressor, condenser, the refrigerating circuit that evaporimeter forms, between compressor and evaporimeter, be provided with reservoir, between condenser and evaporimeter, be provided with device for drying and filtering, described evaporimeter by be in parallel main evaporator, secondary evaporimeter forms, main evaporator, secondary evaporimeter is connected on magnetic valve by capillary respectively, the described magnetic valve other end is connected with the device for drying and filtering in refrigerating circuit, the fin of described secondary evaporimeter and the fin of main evaporator are crisscross arranged, described master, secondary evaporimeter includes the refrigeration pipe of stacked bending, fin and be arranged on the end plate of both sides, on described fin and end plate, offer through hole, refrigeration pipe interconnects fin and end plate by through hole, main evaporator, secondary evaporimeter is by the U-shaped hook phase clamping arranging on the end plate of two ends, the both sides, bottom of described fin all slope inwardly.
Wherein, main evaporator and secondary evaporimeter are up and down to be arranged, the area of secondary evaporimeter is the 30%-100% of main evaporator area.
Preferably, the area of described 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 6-8mm, and secondary evaporator fin spacing is 18-24mm.
The present invention can realize the opening of major and minor evaporimeter being in parallel by solenoid control and close, and according to refrigerator, the demand of refrigerating capacity is decided the use operation of major and minor evaporimeter, thereby has reduced the energy consumption of compressor, has realized refrigerator energy-saving effect.And the structural design of major and minor evaporimeter not only ensured the unobstructed of airflow, and its drainability is also improved.
Brief description of the drawings

Detailed description of the invention
Embodiment 1
Referring to Fig. 1, the layout structure of fin evaporator for refrigerator provided by the invention comprises the refrigerating circuit being made up of compressor 1, condenser 2, evaporimeter 3, between compressor 1 and evaporimeter 3, be provided with reservoir 4, between condenser 2 and evaporimeter 3, be provided with device for drying and filtering 5, described evaporimeter 3 by be in parallel main evaporator 6, secondary evaporimeter 7 form, main evaporator 6, secondary evaporimeter 7 are connected on magnetic valve 9 by capillary 8 respectively, and described magnetic valve 9 other ends are connected with the device for drying and filtering 5 in refrigerating circuit.
When operation, the high-temperature high-pressure refrigerant gas that compressor 1 is discharged is cooling through condenser 2, become the liquid of cryogenic high pressure, after device for drying and filtering 5, shunted by magnetic valve 9, one tunnel enters main evaporator 6 through capillary, another road enters secondary evaporimeter 7 through another capillary, finally collects and enters after reservoir 4, gets back to compressor 1.
When refrigerator needs large cold, magnetic valve 9 is opened two groups of evaporimeters simultaneously, and system is refrigeration for refrigerator fast.In the time that refrigerator only needs less refrigerating capacity, now only open main evaporator 6, close secondary evaporimeter 7, make the refrigerant flow that system held is less, reduce the energy consumption of compressor.Thereby realize the effect to refrigerator energy-saving.
Embodiment 2
The present embodiment is main evaporator 6 in embodiment 1, secondary evaporimeter 7 parallel-connection structure combinations.Referring to Fig. 2, major and minor evaporimeter includes refrigeration pipe 10, the fin 11 of stacked bending and is arranged on the end plate 12 of both sides, on described fin 11 and end plate 12, offer through hole, refrigeration pipe 10 interconnects fin 11 and end plate 12 by through hole, main evaporator 6, secondary evaporimeter 7 are by the U-shaped hook 13 phase clampings that arrange on 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, can be more preferably 6-8mm.Secondary evaporimeter 7 inter fin spaces are larger, and spacing can be 10-30mm, is more preferably 18-24mm.The fin of secondary evaporimeter 7 can be arranged side by side with main evaporator 6 in the time arranging, but better can with main evaporator 6 fin interlaced arrangement, the fin of secondary evaporimeter 7 is arranged in the centre of two main evaporator 6 fin that are adjacent.When refrigeration, in case, wind flows vertically upward from secondary evaporimeter 7 belows, wind flows through between adjacent two fin of secondary evaporimeter 7, above will entering, between main evaporator fin when air channel, be divided into some strands of parallel air currents through main evaporator by top fin, be conducive to the circulation of air.
When 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.
Embodiment 3
The present embodiment is the structural representation that main evaporator 6 in embodiment 2, secondary evaporimeter 7 are staggered place.Referring to Fig. 3, the fin of described secondary evaporimeter 7 is arranged in the centre of two main evaporator 6 fin that are adjacent, the both sides, bottom of described fin all slope inwardly, the defrosting water 14 of fin can fall in minimum point along the angle of inclination below fin in drippage toward below under Action of Gravity Field like this, directly fall in the water-collecting tray of evaporimeter below, avoid the defrosting water of main evaporator to drip on the evaporation tube or fin of secondary evaporimeter, prevented that on secondary evaporimeter, ponding freezes.
