Description
Technical field
The utility model relates to a kind of electric scroll compressor, particularly a kind of car air-conditioner electric scroll compressor.
Background technique
Electric scroll compressor is into a single integrated structure by motor and scroll compression body, and the gas compression processes of scroll compressor has been coiled by two whirlpools.Two whirlpool dishes comprise a quiet whirlpool dish and a movable orbiting scroll, movable orbiting scroll is two involute scroll wrap that structure is identical with quiet whirlpool dish, the two is arranged to the state that angle potential difference is 180 degree, movable orbiting scroll scroll is coiled body around quiet whirlpool under driving and is done tangent oscillating traverse motion having eccentric motor shaft, thereby make to form seal space between two scrolls, and shift to Jing Wo disk center gradually in sealing space, and in transfer process, the volume of seal space diminishes gradually.In three circular movement processes of eccentric motor axle, gas experience is inhaled into, compresses and discharge three processes, thereby realizes the compression process of gas.The suction port of electric scroll compressor or title refluxing opening are located at motor tail end, after air-flow is cooling to machine winding coil, motor bearings and electric machine casing etc. by electric machine casing inside, then enter the compressed discharge of scroll by the intakeport of compressor.As can be seen here, that electric scroll compressor has is simple in structure, volume is little, lightweight, motion steadily, noise is little, cryogenic property good, efficiency is high, and the advantage such as easily be automated, therefore, electric scroll compressor is used to air-conditioning system mostly, particularly in automotive air conditioning system, is used widely.The electric scroll compressor of car air-conditioner is all installed on the electric machine casing of compressor electric motor end conventionally by the driver portion of control system, form the product of electromechanical integrated structure, utilize the feature that electric machine casing temperature is low to carry out hot conduction type radiating and cooling to the heater element of driver, to guarantee that drive operation is normal.Due to the failure rate is low of compressor of this class electric scroll compressor own, therefore, operational reliability and the stability of the reliability and stability of drive operation to this class compressor plays conclusive effect.The driver of car air-conditioner electric scroll compressor mainly comprises driving mainboard, drives mainboard to be provided with field effect transistor and electric capacity.Because field effect transistor has larger heating value, for avoiding the too high apparatus failure that causes of mainboard temperature rise, field effect transistor should have good radiating condition.In view of the consideration of manufacture cost aspect, the field effect transistor on driver is typically provided with multiple, and for improving radiating effect, multiple field effect transistors are all connected on a public radiating fin by its heat dispersing surface.The utility application that the applicant has applied for a kind of car air-conditioner drive controller on March 7th, 2013, this application has been awarded China Patent Right on July 4th, 2013, and its notice of authorization number is CN203081764U.The technological scheme of this patent is by the improvement of this body structure of controller, has improved the radiating effect of driver, has guaranteed that drive operation is stable, and then has improved the reliability of compressor operating.The heat radiation of existing compressor drive be by the hot conduction type of public radiating fin in the support platform of the electric machine casing that is laid in, utilize this platform radiating and cooling of electric machine casing.This support platform arranges along motor length direction, and its one end is positioned at motor tail end, and the other end is positioned at the motor front end near compressor.During due to compressor operating, temperature is higher, and therefore motor is significantly higher than tail end near the front end temperature of compressor, and the radiating and cooling effect of the two has obvious difference.When in ambient temperature, higher or compressor operating time is longer, this species diversity is very remarkable, and easily causes occurring controller failure.Therefore, to compressor generally speaking, also can on the heat dissipation environment of driver, improve, further to improve the reliability of compressor operating.
Summary of the invention
The purpose of this utility model is exactly for the deficiencies in the prior art, a kind of car air-conditioner electric scroll compressor is provided, this compressor carries out cooling by the low-temperature airflow of compressor refluxing opening to the heater element of drive controller, reduce compressor fault rate by the reliability that improves driver, improve stability and the reliability of automotive air conditioning system operation.
