Title:
COOLING-FAN ROTATION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/162648
Kind Code:
A1
Abstract:
Provided is a cooling-fan rotation control device by which it is possible to compensate for a decrease in rotational speed due to wear deterioration of a rotation support unit of the cooling fan. The following are provided: a direct current power supply source (21); a rotation control unit (22) that drives and rotates a cooling fan using the direct current power supplied from the direct current power supply source; and a cooling performance detection unit (23) that detects the cooling performance of the cooling fan. The rotation control unit (22) performs compensation control on the basis of the cooling performance detected by the cooling performance detection unit so that a decrease in cooling performance due to ageing is compensated.
