Document Type and Number:
Japanese Patent JP7017119
Kind Code:
B2
Abstract:
To provide a cooling device of a motor or the like which can improve cooling efficiency in a cabin.SOLUTION: When a normal cooling operation mode is set in a step 220, a control device of a cooling device controls a flow rate adjustment device so that a radiator cooling water passage flow rate is increased as a temperature of a motor becomes high. When it is predicted that the temperature of the motor does not exceed an upper limit of a management temperature for a predetermined period of time from a current time point in steps 230, 240 when an outdoor heat exchanger of a heat pump arranged at the radiator functions as a heat sink, a flow rate suppression operation mode is set in a step 250. When setting the flow rate suppression operation mode, the flow rate adjustment device is controlled so that the radiator cooling water passage flow rate is reduced more than that in the normal cooling operation mode.SELECTED DRAWING: Figure 4
