The utility model relates to a compressor technology and discloses a helicopter refrigeration and compression unit which comprises a compressor and an electromotor arranged in the compressor, wherein the compressor is provided with a shell, the electromotor and a scroll plate are arranged in the shell in the axial direction; the scroll plate is connected with the main shaft of the electromotor; a refrigeration passage is arranged on the outer side of the electromotor; a refrigeration inlet pipe is arranged at an end part, close to the electromotor, of the shell; and a refrigeration outlet pipe is arranged at an end part, close to the scroll plate, of the shell. The electromotor and the compressor are integrated, and a refrigerant in the compressor is utilized to dissipate heat of the electromotor, so that the combined size and weight of the electromotor and the compressor are effectively reduced, and the reliability of the refrigeration system is improved.
Description
Technical field
The utility model relates to Compressor Technology, particularly a kind of helicopter refrigeration compressing apparatus.
Background technology
At present, the evaporation circulating cooling system mainly is made up of compressor, intermediate frequency electrical motor, evaporator, condenser, evaporation fan, condensation fan, expansion valve etc. on the helicopter.Wherein, intermediate frequency electrical motor and compressor are isolating construction, and the intermediate frequency electrical motor is realized refrigeration by the work of belt-driving drive compression machine.But intermediate frequency electric motor overheating amount height need be provided with heat dissipation wind channel and fan etc., and volume is big, and quality is heavy; And belt-driving occupation space size is big, requires high to rigging position and setting accuracy; In addition, compressor operating need be leaned on the adhesive of power-transfer clutch to finish with release and load and unloading, and power-transfer clutch has certain adhesive life-span, and the limited work life of the adhesive life-span of power-transfer clutch and belt has all increased the frequency of plant maintenance, maintenance and replacing.
Summary of the invention
The purpose of this utility model is to provide a kind of helicopter refrigeration compressing apparatus, electrical motor and compressor are integrated, utilize the refrigerant in the compressor that electrical motor is dispelled the heat, can effectively reduce the volume and weight of electrical motor and compressor combination, improve the reliability of refrigeration system.
For achieving the above object, the utility model is achieved by the following technical solutions.
A kind of helicopter refrigeration compressing apparatus, it is characterized in that, comprise compressor and be arranged on the interior electrical motor of compressor, described compressor is provided with housing, the scroll plate that axially is provided with electrical motor and is connected with the main shaft of electrical motor in the housing, the arranged outside of described electrical motor has refrigerating channel, and the end of the close electrical motor of described housing is provided with the refrigeration induction pipe, and the end of the close scroll plate of described housing is provided with the refrigeration outlet pipe.
Characteristics of the present utility model and further the improvement are:
The arranged outside of described electrical motor has vertical heat radiation wing, and described vertical heat radiation wing constitutes described refrigerating channel.
Described refrigeration induction pipe is provided with electrical ball valve.
Described refrigeration outlet pipe is provided with check valve.
Helicopter refrigeration compressing apparatus of the present utility model, comprise compressor and be arranged on the interior electrical motor of compressor, described compressor is provided with housing, the scroll plate that axially is provided with electrical motor and is connected with the main shaft of electrical motor in the housing, the arranged outside of described electrical motor has refrigerating channel, the end of the close electrical motor of described housing is provided with the refrigeration induction pipe, and the end of the close scroll plate of described housing is provided with the refrigeration outlet pipe; Electrical motor and compressor are integrated, utilize the refrigerant in the compressor that electrical motor is dispelled the heat, can effectively reduce the volume and weight of electrical motor and compressor combination, improve the reliability of refrigeration system.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation that a kind of helicopter of the present utility model is used refrigeration compressing apparatus.
Among the figure: 1, refrigerating channel; 2, electrical motor; 3, scroll plate; 4, check valve; 5, housing; 6, main shaft; 7, electrical ball valve; 8, refrigeration outlet pipe; 9, refrigeration induction pipe.
The specific embodiment
With reference to Fig. 1, be the structural representation of a kind of helicopter of the present utility model with refrigeration compressing apparatus.Helicopter of the present utility model comprises compressor and the electrical motor 2 that is arranged in the compressor with refrigeration compressing apparatus, compressor is provided with housing 5, the scroll plate 3 that axially is provided with electrical motor 2 in the housing 5 and is connected with the main shaft of electrical motor 2, the arranged outside of electrical motor 2 has refrigerating channel 1, the end of the close electrical motor 2 of housing 5 is provided with refrigeration induction pipe 9, and the end of the close scroll plate 3 of housing 5 is provided with refrigeration outlet pipe 8; The arranged outside of electrical motor 2 has vertical heat radiation wing, and the wing that vertically dispels the heat constitutes refrigerating channel 1; In addition, refrigeration induction pipe 9 is provided with electrical ball valve 7, and refrigeration outlet pipe 8 is provided with check valve 4.
Helicopter refrigeration compressing apparatus of the present utility model, refrigerant enters refrigerating channel 1 from refrigeration induction pipe 9, compresses by scroll plate 3, and the refrigerant after the compression is discharged from refrigeration outlet pipe 8; Electrical ball valve 7 is initially in closed condition, and during start, electrical motor 2 operations were opened electrical ball valve 7 after 3 seconds, and compressor enters normal operating condition; During shutdown, close electrical ball valve earlier and stop electrical motor 2 runnings after 7,3 seconds again; By this mode, can realize that electrical motor 2 when starting, does not almost have refrigerant, thereby greatly reduced the starting load of electrical motor 2 in the compressor cavity, reach the purpose that reduces the compressor start electric current.
Helicopter refrigeration compressing apparatus of the present utility model, utilize the intermediate frequency electrical motor arbor of helicopter directly to drive scroll plate 3 work, electrical motor 2 and compressor are integrated, utilize the refrigerant in the compressor that electrical motor 2 is dispelled the heat, can effectively reduce the volume and weight of electrical motor 2 and compressor combination, also reduce simultaneously the starting current of compression set, improved the reliability of refrigeration system.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protects, can also make a variety of forms under the enlightenment of this specification sheets, these all belong to the row of the utility model protection.
