The utility model provides a power unit aging device comprising an aging test cabinet for performing aging tests on a power unit and a control cabinet for performing electrical control on the aging test cabinet. A vertically-arranged partition board is arranged in the aging test cabinet to partition the inner space of the aging test cabinet into a front power unit installation cavity and a rear air duct cavity. A test baseboard which is fixedly connected onto the partition board for supporting the power unit is arranged in the power unit installation cavity. The top portion of the air duct cavity is provided with an exhaust fan. The partition board is provided with an air vent at a position corresponding to the position of the power unit. The front door of the aging test cabinet is provided with an air inlet. The air vent formed in the partition board is communicated with the inner cooling air duct of the power unit. Through the traction of the fan, the outside natural wind is sucked into the aging test cabin
