Compared with prior art, a kind of ultra-thin compressor of the present invention, comprises and is sealed in motor in same housing and compressor pump, owing to being arranged with counterbore at rotor one end face, compressor pump can be arranged in counterbore, and and have gap between counterbore inwall.This new structure mode compressor pump is arranged in rotor, greatly reduces whole height or the length of compressor, reduces it and take up room, can make the further miniaturization of compressor.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of a preferred embodiment of the present invention.
Embodiment
In order to make technical problem to be solved by this invention, technological scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, be a preferred embodiment of the present invention, this ultra-thin compressor comprises motor 1 and compressor pump 2, and motor 1 and compressor pump 2 are sealed in same housing 3, and compressor pump 2 is fixed on housing 3.
Motor 1 is brush DC frequency control motor, and it comprises stator 11 and rotor 12.Stator 11 is fixed on housing 3.Be arranged with counterbore 121 at an end face of rotor 12, compressor pump 2 is arranged in counterbore 121, and and has gap 122 between counterbore 121 inwall.Compressor pump 2 is arranged in rotor 12, greatly reduces whole height or the length of compressor, reduces it and take up room, and can make the further miniaturization of compressor.Rotating shaft 123 and the compressor pump 2 of rotor 12 are in transmission connection, and in the present embodiment, rotor 12 and compressor pump 2 adopt the mode of structure of coaxial rotation, both share rotating shaft 123, shorten syndeton length between the two, increase the stability of rotating shaft 123, reduce the swing in its rotation process.
In order to reduce the overall volume of complete machine further, stator 11 is provided with winding 111, rotor 12 adopts rare earth permanent-magnetic material to make, and its internal preset has magnetic pole (not shown).By connecting external control circuit, variable frequency regulating speed control can be carried out easily.
Housing 3 is provided with feed liquor interface 31, goes out liquid interface 32 and termination 33.Termination 33 is for connecting external control circuit and winding 111.Termination 33 is fixed on housing 3, and its one end is located in housing 3, and its other end extends to outside housing 3.
Compressor pump 2 is provided with liquid entering hole 21, and liquid entering hole 21 is connected with feed liquor interface 31.During compressor pump 2 operation, the refrigeration agent from outside enters in the pump housing successively and compresses after feed liquor interface 31 and liquid entering hole 21.Compressor pump 2 can adopt the various structural types such as vane pump, plunger pump or rotor pump.Refrigeration agent after compression is discharged to the pump housing in compressor pump 2, enters in counterbore 121, and collects in housing 3, finally discharges from going out liquid interface 32.In order to increase the refrigeration agent after compression from the mobility to housing 3 in counterbore 121, be provided with perforate 124 in the bottom of counterbore 121.
A kind of ultra-thin compressor of the present invention also has the following advantages:
The first, monnolithic case of the present invention is little, takes up room little, can be used for spatial requirement occasion closely.The height of the housing 3 of above-described embodiment is less than 50 millimeters, and width is less than 80 millimeters.Compare other brush DC frequency variable compressor of same power, the overall volume of the present embodiment reduces about 20% ~ 40%.
The second, the present invention can realize the object of " fast-refrigerating ".Because the rotating speed of brush DC frequency-conversion and speed-regulation motor is not by the restriction of number of poles, as required the rated speed of motor can be designed into more than 3000 revs/min, direct current frequency-variable stepless speed regulation can be carried out easily again by control circuit, thus improve the refrigerating speed of compressor, reach the object of fast-refrigerating.
3rd, the working state that the present invention can also realize " variable refrigeration, low speed maintains ".The refrigerating capacity that compressor of the present invention provides can adapt with the load of equipment, and can operate under low speed, low-pressure ratio condition, thus high frequent can be avoided to start the loss of power wastage and the power generating ratio pressure caused, and significantly can reduce noise.Adopt refrigerating equipment of the present invention comparable general constant speed chiller plant power saving 30% ~ 40%.Simultaneously, because the present invention can be in low speed and load running state in the overwhelming majority time, compared with its capacity, can further improve the capacity ratio of refrigerating equipment heat exchanger, the running of low-pressure ratio state also can increase substantially mechanical efficiency, compression efficiency, the volumetric efficiency of compressor, reduce power consumption, improve efficiency.
4th, the present invention is owing to adopting the DC frequency-changing alignment circuit drive motor 1 on control circuit board, motor 1 can be made to start under very low voltage conditions, thus enough starting torques are obtained when electric current is very little, realize soft start, avoid the impact to electrical network and household electric appliance and interference, and the working life of compressor and motor can be extended.
5th, conventional equipment compressor is that constant speed is run, and in most of working time, the refrigerating capacity of compressor is all considerably beyond the heat load in room, the time of operating at full capacity is only 10% ~ 20%, the surplus of compressor cooling, causes refrigeration agent in vaporizer, can not get sufficient evaporation, does not reach the degree of superheat of requirement, flow of refrigerant dynamic resistance is caused to increase, evaporating temperature declines, and the refrigerating capacity of compressor declines, and energy consumption increases, COP value reduces, and ultra-thin compressor of the present invention then can overcome above-mentioned disadvantage.
6th, the rotor that the present invention adopts adopts binding permanent Rb-Fe-B material, need not field coil, so have energy-conservation, and athermic advantage.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
