초록 ▼

A compressor assembly having an air ducting shroud that can direct a cooling air stream from a fan to components of the compressor assembly, such as a pump assembly. The pump assembly can have at least a pump, a motor and a fan. The compressor can be cooled by providing cooling air to a cylinder hea

대표청구항 ▼

1. A compressor assembly, comprising: a fan;a pump assembly including a motor having a plurality of motor surfaces, a motor shaft having a longitudinal axis, and a motor speed of 5,000 rpm or greater;an air ducting shroud which directs cooling air to at least a portion of the motor and which is adapted to dampen a noise from the pump assembly, the air ducting shroud having: a front inside surface and a rear inside surface;a front blocking partition integrally molded with the front inside surface and in contact with a front motor surface that is parallel to the longitudinal axis of the motor; anda rear blocking partition integrally molded with the rear inside surface and in contact with a rear motor surface that is parallel to the longitudinal axis of the motor, the rear motor surface being on a laterally opposing side from the front motor surface,wherein the blocking partitions block the formation of an airflow between the motor and the front and rear inside surfaces and force the air that is flowing over an outer surface of the motor to only flow along the outer surfaces that are perpendicular to the front and rear motor surfaces; anda sound level having a value of 75 dBA or less when the compressor is in a compressing state. 2. The compressor assembly according to claim 1, wherein the air ducting shroud encases at least a portion of the fan. 3. The compressor assembly according to claim 1, wherein the air ducting shroud encases at least a portion of the motor. 4. The compressor assembly according to claim 1, wherein the air ducting shroud comprises a conduit which directs a cooling air flow to a cylinder head of the pump assembly. 5. The compressor assembly according to claim 1, wherein the air ducting shroud directs a cooling air flow to at least a portion of a pump of the pump assembly. 6. The compressor assembly according to claim 1, wherein the air ducting shroud directs cooling air to at least a portion of a cylinder of the pump assembly. 7. The compressor assembly according to claim 1, wherein the air ducting shroud further comprises a conduit adapted to direct a cooling air flow to a cylinder head of the pump assembly. 8. The compressor assembly according to claim 1, wherein the air ducting shroud has at least one partition which directs a cooling air flow. 9. The compressor assembly according to claim 1, wherein the air ducting shroud encases the motor and directs a first cooling air flow to a first stator coil of the motor and which directs a second cooling air flow to a second stator of the motor and a third cooling air flow to a cylinder head of the pump assembly. 10. The compressor assembly according to claim 1, further comprising a heat transfer rate from the pump assembly having a value of 60 BTU/min or greater when the compressor is in a compressing state. 11. The compressor assembly according to claim 1, further comprising a cooling air flow rate having a value of 50 CFM or greater when the compressor is in a compressing state. 12. The compressor assembly according to claim 1, wherein the motor has a motor efficiency greater than 45 percent. 13. The compressor assembly according to claim 1, wherein the front blocking partition and the rear blocking partition contact front and rear surfaces of the motor. 14. The compressor assembly according to claim 1, wherein the front blocking partition and the rear blocking partition are integrally formed with the outer perimeter of the air ducting shroud. 15. A method of cooling a compressor assembly, comprising the steps of: providing a fan;providing a pump assembly including a motor having a plurality of motor surfaces, a motor shaft having a longitudinal axis and a motor speed of 5,000 rpm or greater;providing an air ducting shroud which directs a cooling air flow, the air ducting shroud having: a front inside surface and a rear inside surface;a front blocking partition integrally molded with the front inside surface and in contact with a front motor surface that is parallel to the longitudinal axis of the motor; anda rear blocking partition integrally molded with the rear inside surface and in contact with a rear motor surface that is parallel to the longitudinal axis of the motor, the rear motor surface being on a laterally opposing side from the front motor surface,wherein the blocking partitions block the formation of an airflow between the motor and the front and rear inside surfaces of the air ducting shroud and force the air that is flowing over an outer surface of the motor to only flow along the outer surfaces of the motor that are perpendicular to the front and rear motor surfaces;cooling the pump assembly with at least a portion of the cooling air flow provided by the fan when the compressor is in a compressing state; andoperating the compressor at a sound level of less than 75 dBA. 16. The method of cooling a compressor assembly according to claim 15, further comprising the steps of: providing a cylinder head of the pump assembly;providing a cooling air flow to cool both the motor and the cylinder head; andorienting the motor such that a portion of the cylinder head can receive at least a portion of cooling air which has not cooled the motor. 17. The method of cooling a compressor assembly according to claim 16, wherein the step of providing an air ducting shroud comprises providing an air ducting shroud having a plurality of conduits, and feeding a cooling air through the plurality of conduits to cool the motor.
