Packaged compressor
The packaged compressor includes inside a package: a compressor main body compressing air; a cooling fan; a fan cover attached to the cooling fan and opened to a suction side and to an upward direction being a delivery side of the cooling fan; an exhaust duct provided above a delivery side opening of the fan cover and extending in a vertical direction; and an air-cooled heat exchanger arranged to be inclined with respect to a vertical direction inside the exhaust duct and configured to exchange heat between air compressed by the compressor main body and air delivered by the cooling fan.
1. A packaged compressor comprising inside a package:
a base having a flat surface;
a compressor main body placed on the base for compressing air;
a cooling fan;
a fan cover attached to the cooling fan and opened to a suction side and to an upward direction being a delivery side of the cooling fan;
an exhaust duct provided above a delivery side opening of the fan cover and extending to an exhaust port in a perpendicular direction to the flat surface of the base and
an air-cooled heat exchanger arranged to be inclined with respect to the perpendicular direction between the cooling fan and the exhaust port inside the exhaust duct so that the cooling fan cannot be directly viewed from the exhaust port and configured to exchange heat between air compressed by the compressor main body and air delivered by the cooling fan.
2. The packaged compressor according to claim 1 , wherein
a suction side opening of the fan cover opens to a horizontal direction, and
the package includes an intake port for introducing cooling air in a height position where the cooling fan cannot be directly viewed through the suction side opening.
3. The packaged compressor according to claim 1 , further comprising a sound insulating plate installed in the perpendicular direction on an upper side and delivered air exit side of the air-cooled heat exchanger inside the exhaust duct.
4. The packaged compressor according to claim 3 , wherein the sound insulating plate is installed so as to cross the delivered air having passed through the air-cooled heat exchanger.
5. The packaged compressor according to claim 4 , wherein a sound absorbing material is stuck to the sound insulating plate.
6. The packaged compressor according to claim 4 , wherein a sound absorbing material is stuck to an inner surface of the exhaust duct on a downstream side of the air-cooled heat exchanger.
7. The packaged compressor according to claim 1 , wherein a sound absorbing material is stuck to an inner surface of the exhaust duct on a downstream side of the air-cooled heat exchanger.
8. The packaged compressor according to claim 2 , further comprising a sound insulating plate installed in the perpendicular direction on an upper side of the air-cooled heat exchanger inside the exhaust duct.
9. The packaged compressor according to claim 5 , wherein a sound absorbing material is stuck to an inner surface of the exhaust duct on a downstream side of the air-cooled heat exchanger.
10. The packaged compressor according to claim 2 , wherein a sound absorbing material is stuck to an inner surface of the exhaust duct on a downstream side of the air-cooled heat exchanger.
