Abstract:
1. A cooling system constructed to cool down an accumulator mounted on a motor vehicle, the cooling system comprising: an air blower configured to have multiple air blow modes of taking in the air from different locations and blowing the intake air to the accumulator; a damper configured to change over connection and disconnection of multiple air flow paths in the multiple air blow modes and thereby switch over a current air blow mode between the multiple air blow modes; a vehicle speed detector configured to detect a vehicle speed of the motor vehicle; and a controller configured to, in response to a switchover demand of the current air blow mode in a state of blowing the intake air to the accumulator via the damper, control the air blower and the damper to switch over the current air blow mode based on the detected vehicle speed of the motor vehicle, wherein when the detected vehicle speed of the motor vehicle is not lower than a preset reference level, the controller controls the air blower and the damper to switch over the current air blow mode in order to satisfy the switchover demand, and when the detected vehicle speed of the motor vehicle is lower than the preset reference level, the controller controls the air blower and the damper to keep the current air blow mode unchanged, irrespective of the switchover demand.
