The invention provides a cooling device for an electrically driven vehicle, which suppresses reduction of cooling capability as much as possible and suppresses noise during cooling. When at least one of a first condition in which the compressor rotation speed is set to be less than or equal to a limited compressor rotation speed preset on the basis of the predetermined noise limit value and a second condition in which the fan rotation speed is set to be less than or equal to a limited fan rotation speed preset on the basis of the predetermined noise limit value is not satisfied. The cooling device (1) sets the corrected compressor rotation speed and sets the corrected fan rotation speed on the basis of the corrected compressor rotation speed such that the noise when the compressor (3) and the fan (41) are operating is equal to or less than a predetermined noise limit value. The cooling device (1) sets the corrected fan rotation speed to a lower value as the corrected compressor rotation speed is higher.
一种电驱动车辆的冷却装置,尽可能地抑制冷却能力的降低并抑制冷却时的噪音。在不满足设定压缩机转速为基于规定的噪音限制值预先设定的限制压缩机转速以下的第一条件和设定风扇转速为基于规定的噪音限制值预先设定的限制风扇转速以下的第二条件中的至少一方时,冷却装置(1)设定修正压缩机转速且基于修正压缩机转速设定修正风扇转速,以使压缩机(3)和风扇(41)工作时的噪音为规定的噪音限制值以下。修正压缩机转速越高,冷却装置(1)将修正风扇转速设定为越低的值。
