Abstract
The invention discloses a double-end same-side staggered 9-shaped micro-channel condenser of a refrigerator. The double-end same-side staggered 9-shaped micro-channel condenser comprises a micro-channel tube and a fixing plate. The micro-channel tube is fixed onto the fixing plate to form S shapes, and grooves are formed in the surface of the fixing plate; adjacent parallel micro-channel tube portions are connected with one another to form 9-shaped curves, the 9-shaped curves at two ends of each micro-channel tube portion face the same side of the fixing plate, and the adjacent 9-shaped curves at the ends of the micro-channel tube portions are staggered from one another. The double-end same-side staggered 9-shaped micro-channel condenser is characterized in that the micro-channel tube fixedly clings into the grooves in the surface of the fixing plate; axial spiral grooves are formed in the inner wall of the micro-channel tube, spiral angles of the axial spiral grooves range from 11 degrees to 17 degrees, and the axial spiral grooves have corrugated sections. The double-end same-side staggered 9-shaped micro-channel condenser has the advantages that the micro-channel tube can be compactly arranged, accordingly, the effective length of the micro-channel tube can be obviously increased, the contact areas of refrigerants and the inner wall of the micro-channel tube can be enlarged, the heat dissipation areas can be enlarged, and the heat exchange efficiency can be obviously improved.
Description
Technical field
The present invention relates to a kind of condenser technology field, more specifically, relate to a kind of condenser for refrigerator.
Background technology
The condenser of existing refrigerator is due to the larger pipe of internal diameter using, and it is little that cold-producing medium and heat exchanger tube inwall contact internal surface area, has be not the condensed heat exchange tube wall of device of part cold-producing medium fully cooling, and the heat transfer effective area of condenser is greatly reduced.In " micropassage type condenser for refrigerator " patent of China Patent No. ZL201220469567.X, between the micro-channel tubes that adjacent parallel is arranged, adopt 9 font curves to connect, and towards the same side, evaporation tube end 9 font curved arrangement are consistent.Although the micropassage type condenser for refrigerator of this structure can be arranged compactly by evaporation tube, increase the effective length of evaporation tube, but it is still compact not that the 9 font curves that are unanimously arranged in parallel are arranged heat exchanger tube, but heat exchange efficiency is still undesirable, and energy consumption is still higher.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of effective length that can significantly increase micro-channel tubes is provided, increase the contact area of cold-producing medium and micro-channel tubes inwall, increasing heat radiation area, significantly improves the two ends homonymy dislocation type 9 font micropassage type condenser for refrigerator of heat exchange efficiency.
The present invention is achieved through the following technical solutions technical goal.
Two ends homonymy dislocation type 9 font micropassage type condenser for refrigerator, comprise micro-channel tubes, fixed head, and described micro-channel tubes is snakelike and is fixed on fixed head, and fixed head surface is provided with groove; The curve shape that is connected to two ends between the micro-channel tubes that adjacent parallel is arranged is 9 fonts, and towards the same side, its improvements are: the adjacent 9 font curve dislocation at described micro-channel tubes two ends are arranged.
The further technical scheme of the present invention is: described micro-channel tubes is close in the lip-deep groove that is fixed on fixed head.
The present invention further technical scheme is: described micro-channel tubes inwall is provided with axial screw groove, and the helical angle of described axial screw groove is 11 °～17 °.
The present invention further technical scheme is: the cross sectional shape of axial screw groove is corrugated.
The present invention compared with prior art, has following good effect:
1. the adjacent 9 font curve dislocation at micro-channel tubes two ends are arranged, the adjacent 9 font curves of the micro-channel tubes being arranged in parallel are avoided mutually, micro-channel tubes is arranged compactlyer like this, has significantly increased the effective length of evaporation tube, thereby has significantly improved heat exchange efficiency.
2. micro-channel tubes inwall is made the tank circuit, has increased the contact area of cold-producing medium and micro-channel tubes inwall, thereby has increased heat exchange area.The increase of heat exchange area can improve heat exchange property and heat transfer rate.
3. the micro-channel tubes inwall tank circuit is made the corrugated helicla flute that becomes 11 °～17 ° with tubular axis line, makes flowing of tube refrigerant fluid more even, thereby obtains better even cooling effect.

Fig. 4 is the I part enlarged diagram in Fig. 2.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
The homonymy dislocation type of two ends shown in accompanying drawing 9 font micropassage type condenser for refrigerator, comprise micro-channel tubes 2, fixed head 1, and micro-channel tubes 2 is snakelike and is fixed on fixed head 1, and fixed head 1 surface is provided with groove 3; The curve shape that is connected to two ends between the micro-channel tubes 2 that adjacent parallel is arranged is 9 fonts, and towards the same side, the adjacent 9 font curve dislocation at described micro-channel tubes 2 two ends are arranged.
In order further to improve heat transfer effect, micro-channel tubes 2 is close in the lip-deep groove 3 that is fixed on fixed head 1; Micro-channel tubes 2 inwalls are provided with axial screw groove 4, and the cross sectional shape of axial screw groove 4 is corrugated, and the helical angle of axial screw groove 4 is 11 °～17 °, and in the present embodiment, the helical angle of axial screw groove 3 is 15 °.
