Below with reference to Fig. 1-Fig. 7, the Rotary Compressor 100 according to this utility model first aspect embodiment is described.Rotary Compressor 100 includes rolling piston compressor, oscillating compressor, rotary blade type compressor etc..In the application as explained below, illustrate for Rotary Compressor 100 for rolling piston compressor.
As shown in Fig. 1-Fig. 7, the Rotary Compressor 100 such as rolling piston compressor according to this utility model first aspect embodiment, including housing 1, motor 2, compression mechanism, two allotters 4 and at least one intubate 5.
Motor 2 and compression mechanism are each provided in housing 1, compression mechanism includes base bearing 31, cylinder assembly, supplementary bearing 32 and bent axle 34, base bearing 31 and supplementary bearing 32 are respectively provided at the axial two ends of cylinder assembly, and one end of bent axle 34 is connected with motor 2 and other end traverse base bearing 31, cylinder assembly and supplementary bearing 32.Cylinder assembly includes at least one cylinder 32, and cylinder 32 is formed compression chamber 321 and at least one jack 322.When Rotary Compressor 100 such as rolling piston compressor works, bent axle 34 can drive to drive the piston 35 being set in outside its eccentric part 341 to roll along the inwall of compression chamber 321 by motor 2, thus the coolant entered in compression chamber 321 is compressed.
When cylinder assembly includes a cylinder 32, Rotary Compressor 100 such as rolling piston compressor is single cylinder compressor.When cylinder assembly includes multiple cylinder 32, being provided with dividing plate between adjacent two cylinders 32, now Rotary Compressor 100 such as rolling piston compressor is multicylinder compressor.
Two allotters 4 are respectively provided at the axial two ends of cylinder 32, one of them in two allotters 4 is formed outlet 42 (or the form for one section outlet 42 pipe), another in two allotters 4 is formed entrance 41 (or being the form of one section of entrance 41 pipe).Intubate one end of 5 to be connected with one of them in two allotters 4, intubate the other end of 5 and be connected with another in two allotters 4 after jack 322.Intubate 5 all to connect with the inside of two allotters 4.When Rotary Compressor 100 such as rolling piston compressor works, cooling medium can be entered by this allotter 4 by another the entrance 41 above-mentioned in two allotters 4 and intubate 5, heat cooled compressed mechanism such as cylinder 32 are absorbed in 5 intubating, namely cool down in the process of Rotary Compressor 100 such as rolling piston compressor compression refrigerant, make compression process close to isotherm compression process, thus significantly improving compression process, reduce the work done during compression of coolant.Cooling medium after heat exchange is discharged again through one of them the outlet 42 above-mentioned in two allotters 4.
Alternatively, cooling medium can be the medium identical with the coolant of compression in compression chamber 321, even if now cooling medium occurs that leakage nor affects on the properly functioning of Rotary Compressor 100 such as rolling piston compressor.When Rotary Compressor 100 such as rolling piston compressor operates, can from the entrance 41 of allotter 4 to intubating injection liquid cooling medium in 5, liquid cooling medium absorbs the amount of heat of coolant generation in compressor and becomes gaseous state after the heat of cylinder 32, and gaseous cooling medium is by exporting 42 outflows.The gaseous cooling medium flowed out (such as, condenser etc.) can be cooled into liquid outside housing 1, and liquid cooling medium flow back into intubate again and continues in 5 compression mechanism is cooled down.Certainly, cooling medium can also be the medium with gas-liquid two-phase state, for instance, freon, water, ethanol, methanol etc..
Cylinder 32 is cooled down the method being the most effectively reduce coolant compress work per mass.By jack 322 is located on cylinder 32, the close together of jack 322 Range compress chamber 321 inwall, intubate the contact area between 5 and cylinder 32 big, it is possible to better the coolant in compression chamber 321 is cooled down, and heat exchange efficiency is high.It addition, intubate 5 by employing, being not easy leakage owing to intubating 5, reliability is high, thus improve the reliability of Rotary Compressor 100 such as rolling piston compressor.
Alternatively, the minimum range between inwall and the inwall of compression chamber 321 of jack 322 is t, and wherein, t meets: t >=0.3mm.Thus, it is possible to be effectively ensured intensity and the sealing of the inwall of compression chamber 321.
In order to reduce the thermal contact resistance intubated between 5 and cylinder 32, improving heat exchange property, it is possible to carry out expansion tube process when assembling to intubating 5, namely intubating 5 can with cylinder 32 tube expanding joint after jacks 322.
Rotary Compressor 100 such as rolling piston compressor according to this utility model embodiment, by arranging allotter 4 and being located in cylinder 32 intubates 5, compression mechanism can be cooled down, thus reducing the delivery temperature of cylinder 32, improve the efficiency of Rotary Compressor 100 such as rolling piston compressor.
