A cooling system includes: a coolant circuit through which a coolant for cooling an electric motor and electrical equipment circulates; a pump that feeds the coolant; and a degas tank that separates the bubbles from the coolant. The coolant circuit connects the devices in series. The degas tank is disposed at an upper stage, a first device as at least one of the electric motor, the electrical equipment, and the pump is disposed at a lower stage, and a remaining second device is disposed at a position that is above the lower stage and is as high as the degas tank or lower than the degas tank. The coolant circuit connects the degas tank, the second device, and the first device in this order, and the coolant flows in this order.

Cooling system for electric drive vehicle

To suppress cooling performance from being degraded by bubbles in a coolant in a cooling system for an electric drive vehicle, the cooling system includes: a first coolant circuit through which the coolant for cooling an electric motor and electrical equipment circulates; a first pump that is connected to the first coolant circuit and feeds the coolant; and a first degas tank that is connected to the first coolant circuit and separates the bubbles from the coolant. The first coolant circuit connects the electric motor, the electrical equipment, the first pump, and the first degas tank in series. The first pump and the electric motor are connected in a manner to be sequentially aligned in the first coolant circuit. The coolant flows from the first pump to the electric motor.

A vehicle radiator support structure which includes a plurality of upper holding members each attached to an upper shroud member which is one of a plurality of structural members of a vehicle body and configured to hold an upper portion of a radiator in such a manner as to restrict a horizontal relative displacement thereof. At least one pair of lateral elastic members is each attached to a respective one of right and left lateral portions of the radiator. At least one pair of lateral engagement members is each attached to another one of the structural members other than the upper shroud member and configured to come into contact engagement with at least an upper portion of a respective one of the lateral elastic members.
