2, of the present inventionly outer around foam back-up ring bottom, be provided with breach, and the part that the surface of squirrel-cage wire tube condenser and drip tray are adjacent is exposed to indentation, there and exposes, can improve the air velocity between squirrel-cage wire tube condenser and drip tray like this, to take away fast the hot-air in this region.
Accompanying drawing explanation
Fig. 1 is side view of the present invention;
Fig. 2 is front view of the present invention;
Fig. 3 is installation diagram of the present invention;
Number in the figure: 1 is outer around foam back-up ring; 2 foams block up core; 3 condenser inlet; 4 condensator outlets; 5 squirrel-cage wire tube condensers.
The specific embodiment
In the present embodiment, a kind of squirrel-cage wire tube condenser of the refrigerator with dual wind shielding structure, is arranged in the compressor reducer storehouse adjacent with back boards, and squirrel-cage wire tube condenser 5 is divided into successively overheated zone, two-phase section and crosses cold-zone along its axial direction; Initiating terminal in overheated zone is provided with condenser inlet 3, at the end of crossing cold-zone, is provided with condensator outlet 4,
As shown in Figure 1, outside the overheated zone of squirrel-cage wire tube condenser 5 arranged outside has around foam back-up ring 1; Around foam back-up ring 1, be filled in and in the outer ring of squirrel-cage wire tube condenser 5 and the space between compressor reducer storehouse inner surface and postnotum, form outer ring and axially seal wind shielding structure in addition; Be fastened in the condenser storehouse of laying squirrel-cage wire tube condenser 5, thus can further isolate near overheated zone hot-air with opposite side two-phase section, cross near the cold air " blending " in cold-zone.
The place, axle center of crossing cold-zone end at squirrel-cage wire tube condenser 5 is provided with the stifled core 2 of foam, and what the stifled heart 2 of foam was arranged on squirrel-cage wire tube condenser 5 crosses termination, cold-zone; The stifled shape of the heart 2 of foam matches with the inner ring profile of squirrel-cage wire tube condenser 5, thereby foam being blocked up in the inner ring that core 2 is filled in squirrel-cage wire tube condenser 5, form inner ring axially seals wind shielding structure; With the axial wind shielding structure in outer ring and the axial wind shielding structure of inner ring, form dual wind shielding structure.
Concrete, as shown in Figure 2,1/2nd places of overheated zone that are set in squirrel-cage wire tube condenser 5 around foam back-up ring 1 are outward between the end of overheated zone.
As shown in Figure 3, around the bottom of foam back-up ring 1, be provided with breach outward, the drip tray position of gap position and squirrel-cage wire tube condenser 5 bottoms matches, thereby makes the surface part adjacent with drip tray of squirrel-cage wire tube condenser (5) be exposed to indentation, there.
As shown in Figure 3, around foam back-up ring 1, should surround outward two sides and the end face of squirrel-cage wire tube condenser, bottom side (being the surface part adjacent with drip tray of squirrel-cage wire tube condenser 5) reserves space (being breach); Meanwhile, the stifled core 2 of foam should block squirrel-cage wire tube condenser 5 innermost circle centers (being the axle center of squirrel-cage wire tube condenser 5) path, and the shape of the two as shown in Figure 3.
Outside adding, after foam back-up ring 1, the axial invalid air-flow directly flowing through from outside and the space between postnotum of squirrel-cage wire tube condenser 5 is blocked, and effective throughput of radially skimming over condenser fiber tube heat exchange abundant with it is increased; Near having isolated overheated zone, high temperature air flow to two-phase section and crosses cold-zone simultaneously; On foam back-up ring 1, be with jagged outward, and the part that the surface of squirrel-cage wire tube condenser and drip tray are adjacent is exposed to indentation, there and exposes, can improve the air velocity between squirrel-cage wire tube condenser and drip tray like this, to take away fast the hot-air in this region.The existence of the stifled core 2 of foam has stopped from squirrel-cage wire tube condenser center the axial invalid throughput of directly passing and not carrying out heat exchange with condenser, and the two acting in conjunction can improve condenser overall heat exchange performance, thereby increases degree of supercooling, finally reduces energy consumption of refrigerator.
Refrigerator of the present invention is compared with temperature and the power consumption of squirrel-cage wire tube condenser and traditional squirrel-cage wire tube condenser, its result as shown in Table 1 and Table 2:
The temperature comparative result of squirrel-cage wire tube condenser and traditional squirrel-cage wire tube condenser for table 1 refrigerator of the present invention
As can be seen from Table 1, add the foam 1 that keeps out the wind and can effectively improve squirrel-cage wire tube condenser 5 surrounding air flow fields, reduce the two-phase section of squirrel-cage wire tube condenser 5 and cross cold-zone ambient air temperature; Effectively reduce the import of squirrel-cage wire tube condenser 1, middle part and outlet temperature, improve degree of supercooling, after degree of supercooling is enhanced, can reduce the entrance mass dryness fraction of evaporimeter, increases refrigerating capacity, thereby improve refrigerator efficiency.
The power consumption comparative result of squirrel-cage wire tube condenser and traditional squirrel-cage wire tube condenser for table 2 refrigerator of the present invention
As can be seen from Table 2, refrigerator of the present invention is compared with traditional squirrel-cage wire tube condenser with squirrel-cage wire tube condenser, and refrigerator power consumption reduces approximately 5%.
As shown in Figure 3; in order to improve refrigerator, use squirrel-cage wire tube condenser surrounding air flow field; condenser windward overheated zone, downstream part arrange outside around foam back-up ring 1; and set up the stifled core 2 of foam at the upper cold-zone end shaft core position of swimming across; to optimize squirrel-cage condenser 5 surrounding air flow fields; the axial invalid throughput of condenser is reduced; radially effectively throughput increases; and stop shutdown post-condenser overheated zone and two-phase section, cross near the cold and hot air blending in cold-zone, thereby improve condenser overall heat exchange performance.
