Document Type and Number:
Japanese Patent JPH05248239
Kind Code:
A
Abstract:
PURPOSE:To increase an engine cooling performance by adding an axial flow fan blasting air from an engine side to a radiator side placed at a center to a rotary disc of a centrifugal fan taking cooling air into a radiator. CONSTITUTION:A water cooling engine 2 is provided in such a condition that a shaft faces in the front and rear directions in a bonnet 1 arranged at the front of a tractor for agriculture. A radiator 3 for cooling the engine 2 is provided, such that it is positioned at the front of the engine 2. A centrifugal fan 4 for taking cooling air into a radiator 3 is provided between the engine 2 and the radiator 3 in such a condition that a rotary disc 4a is placed opposite to the radiator 3. A plurality of blades 4b are arranged at the rotary disc 4a on the side of the radiator 3. An axial flow fan 7 which feeds hot air from the side of a radiator 2 to the side of radiator 3 is added at the center of the rotary disc 4a to exhaust hot air by force from the part between the centrifugal fan 4 and the engine 2. In this way, the engine cooling performance is improved.
