Title:
COOLING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/085439
Kind Code:
A1
Abstract:
A cooling control device (60) comprises: an inverter control unit that controls the switching of an inverter (21) in order to drive a rotating electrical machine (20); and a cooling control unit that, on the condition that switching control has been stopped, controls the driving of a cooling device (31) so that when a for-control temperature, which is either a detection value of temperature sensors (40-43) that detect the temperature of at least one component to be cooled of the inverter and the rotating electrical machine or an estimation value of a temperature estimation unit (60a) that estimates the temperature of the component to be cooled, is determined to be equal to or less than a threshold value, the cooled degree of the component to be cooled by the cooling device is lowered to a greater extent than when the for-control temperature exceeds the threshold value.
