Abstract
The utility model relates to new structure for a rotary full-closed cooling compressor, which solves cooling problem upon rotary compressor when no forced air flows, recovers work calories for the motor of the compressor and can effectively improve the performance coefficient of the compressor working under heat pump mode. The utility model comprises a compressor and an intermediate-wall-type heat exchanger arranged on the motor of the compressor and is characterized in that: a small hole is arranged at the bottom part of a miscella separator for of the full-closed rotary compressor; a duct is welded in the hole and is connected with the inlet at the bottom part of the intermediate-wall-type heat exchanger, the upper outlet of which is connected with the suction duct of the compressor; when the compressor is running, the refrigeration working medium of liquid separated from the bottom part of the miscella separator for the compressor flows into the intermediate-wall-type heat exchanger under the action of pressure difference; the medium absorbs heat of the motor at the inner part and is evaporated into steam and flows back to the compressor through a steam return pipe. Temperature rise on the surface of the motor can be conveniently adjusted through adjusting the liquid content of refrigerant gas in the steam return pipe of the compressor, thereby realizing the purpose of cooling the compressor.
Description
Technical field
The utility model belongs to a kind of new structure of cooling rotary type totally-enclosed compressor, and particularly a kind of have the remarkable compressor operating performance of improving, and reclaims the new structure of the cooling rotary type totally-enclosed compressor of compressor electric motor heating value.Be applicable to all kinds of rotary compressors, be specially adapted to adopt the rotary type totally-enclosed compressor of heat pump mode work.
Background technique:
Because rotary type totally-enclosed refrigerant compression is confidential to be sealed by the lubricant oil in the moving element gap, therefore be that separation is fuel-displaced from exhaust, must make high pressure in the casing, therefore, motor, compressor are overheated easily, and the method for cooling compressor, producer's fitness for purpose is forced air cooling.When cool condition was undesirable, compressor can break down.
There are two problems in forced air cooling:
1, need not dispose in the refrigeration and heat-pump apparatus of fan at some, this condition is difficult to satisfy.
When 2, compressor was worked under heat pump mode, heat loss was excessive.The heat of its loss had both comprised the heating value of air compressor motor, also comprised the part sensible heat heat of compressor high pressure gas, had reduced the heating efficiency of heat pump mode.
Obviously, adopt the cooling scheme of forced air cooling to have certain narrow limitation to rotary compressor.
Summary of the invention:
The purpose of this utility model provides a kind of new structure of cooling rotary type totally-enclosed compressor.It can reach the cooling compressor motor, makes it not occur superheating phenomenon, can realize reclaiming the purpose of compressor electric motor work calories again.Be applicable to all kinds of rotary compressors, particularly with the rotary compressor of heat pump mode work.
The purpose of this utility model is achieved by the following technical solution: it comprises compressor and is installed in the dividing wall type heat exchanger at compressor electric motor position, it is characterized in that: the bottom of the vapor-liquid separator of rotary type totally-enclosed compressor is provided with an aperture, welded pipe line in the hole, link to each other with the import of the dividing wall type heat exchanger bottom that is installed in the compressor electric motor position, the top outlet of dividing wall type heat exchanger links to each other with the aspirating air pipe of compressor, during compressor operating, from the isolated liquid refrigerating working medium in compressor vapor-liquid separator bottom, under action of pressure, flowed into dividing wall type heat exchanger, portion has absorbed the heat of air compressor motor within it, be evaporated to gas, got back to compressor again by muffler.By adjusting the liquid content of refrigerant gas in the compressor return air pipe, can adjust the temperature rise on compressor electric motor surface easily.So, realized the purpose of cooling compressor.
The advantage that the utlity model has: owing to isolated liquid in the employing compressor vapor-liquid separator comes the motor of cooling compressor.Make the efficient of compressor vapor-liquid separator improve, reduced the chance that compressor directly sucks liquid, improved the mass dryness fraction of compressor suction gas simultaneously, favourable to the output cold and the heat under the heat pump operating mode that improve compressor, both reduce the temperature rise of compressor electric motor, reclaimed the heating value of compressor electric motor again.This scheme is to need be with system's advantageous particularly of heat pump mode work.Reduce energy consumption, improved the heating capacity of system, increased substantially the coefficient of performance when compressor heats.
Description of drawings:
Fig. 1, Fig. 2 are the utility model embodiment's structural representations.
Embodiment
See Fig. 1, during totally-enclosed compressor 8 work, remained at the bottom of vapor-liquid separator 3 by vapor-liquid separator 3 isolated liquid refrigerants 6, because the outlet of the top of dividing wall type heat exchanger 11 is connected on sucking pipe 2 places of vapor-liquid separator 3, the pressure at this place is less than the pressure at liquid refrigerant 6 places, therefore, liquid refrigerant 6 flows into the inside of dividing wall type heat exchanger 11 by the lower inlet pipe 7 of dividing wall type heat exchanger 11, because the outside of dividing wall type heat exchanger 11 closely contacts with the iron core of compressor electric motor, so, the work calories of motor 10 conducts the liquid refrigerant to dividing wall type heat exchanger inside, evaporation became gas after refrigeration agent absorbed heat, enter the sucking pipe 2 of vapor-liquid separator from the top outer pipe of dividing wall type heat exchanger, got back to compressor 8, so continuous operation has absorbed the heating value of the motor 10 of compressor 8, has realized the purpose of the motor 10 of cooling compressor 8.
Dividing wall type heat exchanger of the present utility model should be installed in electric machine iron core around, both can be installed in the inside of compressor housing, also can be installed in the outside of compressor housing.Accompanying drawing 2 promptly is the embodiment's schematic representation that it is installed in totally-enclosed outside.
The inlet tube 7 of dividing wall type heat exchanger 11 guarantees sealing with adopting outer pipe 1 and being connected of vapor-liquid separator, and gastight technology realizes, is generally welding.
When dividing wall type heat exchanger 11 is installed, should guarantee that the inboard of the outer surface of heat exchanger closely contacts with the motor 10 of compressor 8, make the heat of motor 10 can successfully pass to dividing wall type heat exchanger 11.
In the outside on dividing wall type heat exchanger 11 surfaces and the outer surface of compressor vapor-liquid separator 3, heat-insulating material 9 and 5 can be installed, be used for reducing compressor electric motor heat and the effectively loss of cold.
