Title:
RADIATOR FOR AUTOMOBILE
Document Type and Number:
Japanese Patent JPS5946316
Kind Code:
A
Abstract:
PURPOSE:To ensure that air flow resistance is reduced at the time of high- speed running and the quantity of forced air flow is enlarged at the time of low- speed running, by a method wherein the spacing between a cooling fan and a main body of a radiator is enabled be varied. CONSTITUTION:In low-speed running or idling, when a motor M is driven to rotate the cooling fan 2, air is sucked from the front side of the radiator by the fan 2 and is blasted to the side of the motor M. Due to a reaction force of the blasting, the fan 2 is moved to the solid-line position, and is rotated in the condition wherein the center thereof makes contact with a stopper 8. Therefore, the tip clearance between the fan 2 and a shroud 3 is reduced, thereby increasing the air intake quantity and enhancing heat transfer efficiency of the radiator. At the time of high-speed running, the motor M is stopped, the fan 2 is returned to the dotted-line position due to the pressure of the airflow 9 generated during the running of the vehicle, whereby the tip clearance is enlarged to reduce air flow resistance. Accordingly, the heat transfer efficiency of the radiator can be maintained to be high even at the time of high-speed running.
