Abstract: A two-phase cooling system of an electric work vehicle includes a compressor, a condenser, a thermal expansion valve, a heat exchanger, and an evaporator. The compressor compresses a refrigerant in vapor form to increase the refrigerant pressure. The condenser is downstream of the compressor and discharges heat from the refrigerant flowing from the compressor to condense at least a portion of the refrigerant. The thermal expansion valve is downstream of the condenser and decreases the pressure of the refrigerant to vaporize the refrigerant from liquid form to vapor form to decrease the temperature of the refrigerant. The heat exchanger is coupled to an electrical component and is used to transfer heat from the electrical component to the refrigerant from the electrical component. The refrigerant then flows through the evaporator, where it absorbs more heat. The refrigerant than passes back through the thermal expansion valve on its return to the compressor.

Abstract: The present disclosure provides a two phase oil cooling system for a work vehicle. The system includes a condenser, an evaporator, a refrigerant path, and a pump. The condenser cools a refrigerant from vapor form to liquid form. The evaporator exchanges heat between a first fluid of the work vehicle and the refrigerant, and heats the refrigerant from liquid form to vapor form. The refrigerant path comprises a first refrigerant path thermally coupling the condenser to the evaporator and a second refrigerant path thermally coupling the evaporator to the condenser. The refrigerant flows through the refrigerant path. The pump is positioned in the first refrigerant path for pumping the refrigerant from the condenser to the evaporator, such that the evaporator is downstream of the pump and the condenser is downstream of the evaporator.
