Package type compressor
View Patent ↗A package type compressor includes a housing, a compressor, a motor, an inverter, and a cooling fan. The housing has an air inlet. The compressor is disposed inside the housing where it compresses the air. The compressor is disposed in a compressor body inside the housing. The motor is disposed above the compressor inside the housing, and drives the compressor. The inverter is disposed in the region of the air inlet of the housing, and controls a rotation speed of the motor. The cooling fan is disposed inside of the compressor body. The cooling fan generates a flow path of cooling air within the package type compressor. The inverter is disposed in such a way that as the flow path of cooling air enters the air inlet of the housing, the flow path of cooling air passes directly over the inverter thereby cooling the inverter.
1. A package type compressor comprising:
a compressor body including a cooling fan;
an after cooler cooling compressed air compressed by the compressor body;
a motor driving the compressor body;
an inverter controlling a rotation speed of the motor;
an air tank being disposed between and immediately adjacent to the inverter and the after cooler; and
a housing that stores the compressor body, the after cooler, the motor, and the inverter, wherein
the inverter and the motor are arranged between an intake port provided in the housing and the discharge port of the cooling fan,
an air supply port of a flow path for cooling the compressor body is provided at the discharge port of the cooling fan,
the after cooler is disposed between a discharge port of the flow path and a discharge port provided in the housing, and
the air tank is enclosed within a first separate compartment that is different from a second compartment in which the compressor body is enclosed, the first separate compartment being formed in a corner of the housing.
2. The package type compressor according to claim 1 , wherein a rotating shaft of the cooling fan rotates integrally with a rotating shaft of the compressor body.
3. The package type compressor according to claim 1 , wherein a path of the compressed air compressed by the compressor body is provided between the discharge port of the flow path and the discharge port provided in the housing.
4. The package type compressor according to claim 1 , wherein a path of the compressed air is a pipe connecting the compressor body to the after cooler.
5. The package type compressor according to claim 1 , wherein a path of the compressed air is a pipe connecting the after cooler connected to the compressor body to the air tank.
6. The package type compressor according to claim 3 , wherein the path of the compressed air is a pipe connecting the air tank storing the compressed air to an air dryer.
7. The package type compressor according to claim 1 , wherein a plurality of intake ports are provided in the housing.
8. The package type compressor according to claim 7 , wherein the inverter and the motor are arranged between at least one intake port of the plurality of intake ports and the cooling fan.
9. The package type compressor according to claim 1 , wherein the compressor body is a scroll compressor.
