  • Dual loop blended cooling
    Patent number: 12215907
    Abstract: A thermal management system includes a refrigerant loop including a compressor, a condenser, an expansion element, and a chiller. A first coolant loop of the thermal management system includes the chiller, a first cooling heat exchanger disposed downstream of the chiller, and a distribution valve disposed downstream of the first cooling heat exchanger. A coolant flow path branches from the first coolant loop with the coolant flow path extending from the distribution valve to a re-entry point where the coolant flow path rejoins the first coolant loop at a position downstream of the distribution valve. The coolant flow path includes an electric component, and the distribution valve is configured to control a distribution of the first coolant flowing towards the electric component and the re-entry point.
