연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A cooling system for cooling portions of a farm machine, the cooling system comprising: a rotary blower including a housing and having a first rotor and a second rotor rotatably disposed in the housing, the first and second rotors having meshed lobes for transporting air from an inlet port to an outlet port, the rotary blower further including a first rotor shaft and a second rotor shaft rotatably supported by the housing and having the first and second rotors, respectively, fixed for rotation therewith; anda manifold coupled to the outlet port of the rotary blower and branching into a first branch conduit and a second branch conduit,wherein the first branch conduit directs a first portion of cooling air from the rotary blower onto a first component for cooling thereof, andwherein the second branch conduit directs a second portion of cooling air from the rotary blower onto a second component for cooling thereof. 2. The cooling system of claim 1 wherein the first component comprises a turbocharger. 3. The cooling system of claim 2 wherein the second component comprises at least one of an engine accessory, engine oil and engine coolant. 4. The cooling system of claim 3 further comprising a valve that is disposed in the manifold and selectively actuated by a controller for modifying a ratio of air delivered to the first and second components. 5. The cooling system of claim 1 wherein the inlet port extends along an inlet port axis and the outlet port extends along an outlet port axis, wherein the inlet port axis and the outlet port axis are parallel. 6. The cooling system of claim 5 wherein the inlet port is defined by an inlet cylinder provided on the housing, and wherein the inlet port defines a circular cross section. 7. The cooling system of claim 5 wherein the outlet port is defined by an outlet cylinder provided on the housing, and wherein the outlet port defines a circular cross section. 8. The cooling system of claim 5 wherein the housing comprises an eyelet extending therefrom, the eyelet defining an opening having an axis that is parallel to the inlet port axis and the outlet port axis. 9. The cooling system of claim 1, further comprising an aftertreatment system including: a first aftertreatment enclosure configured on the farm machine and having a first inlet, a second inlet and an outlet, wherein the first inlet receives engine exhaust from an engine of the farm machine and the second inlet receives air from the rotary blower and wherein a temperature of the engine exhaust is reduced upon exiting the first aftertreatment enclosure through the outlet. 10. The cooling system of claim 1 wherein the farm machine comprises a combine. 11. An air delivery system for a farm machine, the air delivery system comprising: a rotary blower including a housing and having a first rotor and a second rotor rotatably disposed in the housing, the first and second rotors having meshed lobes for transporting air from an inlet port to an outlet port, the rotary blower further including a first rotor shaft and a second rotor shaft rotatably supported by the housing and having the first and second rotors, respectively, fixed for rotation therewith; anda manifold that directs the air from the rotary blower into an engine air filter in a direction opposite an air intake direction through the engine air filter, wherein the air from the rotary blower urges debris away from the engine air filter. 12. The air delivery system of claim 11 wherein the air is delivered from the rotary blower in intermittent blasts. 13. The air delivery system of claim 11, further comprising a valve disposed in the manifold that is selectively actuated by a controller to control a timing of the intermittent blasts. 14. The air delivery system of claim 11 wherein the inlet port extends along an inlet port axis and the outlet port extends along an outlet port axis, wherein the inlet port axis and the outlet port axis are parallel. 15. The air delivery system of claim 11 wherein the inlet port is defined by an inlet cylinder provided on the housing and wherein the inlet port defines a circular cross section, and wherein the outlet port is defined by an outlet cylinder provided on the housing and wherein the outlet port defines a circular cross section. 16. A method of cooling portions of a farm machine, the method comprising: providing a rotary blower on the farm machine;providing a manifold that directs air from the rotary blower through a first branch conduit and a second branch conduit;delivering a first portion of cooling air from the rotary blower, through the manifold first branch conduit and onto a turbocharger to thereby cool the turbocharger; anddelivering a second portion of cooling air from the rotary blower, through the manifold second branch conduit and onto a component to thereby cool the component, wherein the component is at least one of an engine accessory, engine oil, and engine coolant. 17. The method of claim 16, further comprising: providing a valve in the manifold; andselectively actuating the valve to modify an air flow ratio between the first and second branch conduits. 18. The method of claim 16, further comprising: providing an aftertreatment enclosure having a first inlet, a second inlet, a first outlet, and a second outlet;providing the manifold with a third branch conduit fluidly coupled to the aftertreatment enclosure;delivering engine exhaust through an exhaust duct into the first inlet and out of the first outlet of the aftertreatment enclosure; anddelivering a third portion of cooling air from the rotary blower, through the manifold third branch conduit and into the second inlet and out of the second outlet of the aftertreatment enclosure to cool the engine exhaust in the exhaust duct. 19. The cooling system of claim 1, wherein the rotary blower is a Roots type supercharger operably coupled to the engine by a mechanical power transfer device. 20. The cooling system of claim 1, further comprising an aftertreatment enclosure configured to receive an exhaust duct and having a first inlet, a second inlet, a first outlet, and a second outlet, wherein the first inlet receives engine exhaust from an engine and the second inlet receives a third portion of cooling air from the rotary blower to reduce a temperature of the engine exhaust passing through the aftertreatment enclosure, wherein the engine exhaust exits the first aftertreatment enclosure through the first outlet, and the third portion of cooling air is vented to ambient through the second outlet, and wherein the manifold includes a third branch conduit coupled to the second inlet of the aftertreatment enclosure to supply the third portion of cooling air thereto.
