  • Publication number: 20250001829
    Abstract: A vehicle thermal management system includes a heat pump system, a cabin coolant loop, a low-temperature coolant loop. The heat pump system includes a compressor, a water condenser, an outside heat exchanger, a chiller, an evaporator, a gas-liquid accumulator, a first electronic expansion valve, a second electronic expansion valve, a third electronic expansion valve, and a first four-way valve. The cabin coolant loop includes a first water pump, a coolant heater, a one-way valve, and a heater core. The low-temperature coolant loop includes an electric drive cooling module, a battery pack, a second water pump, a second four-way valve, a three-way valve, a radiator and a hot bottle. A fan and a blower are used to control the front end and cabin airflow. The vehicle thermal management system to provide multiple working modes to assure cabin thermal comfort, control humidity and component temperature with low energy consumption.

  • Patent number: 11571944
    Abstract: A thermal system for a vehicle includes a high temperature coolant loop thermally coupled to a heater core, a low temperature coolant loop thermally coupled to at least one of an electric motor and power electronics, and a first four-way valve configured to selectively fluidly couple the high temperature coolant loop and the low temperature coolant loop such that coolant heated by the electric motor and/or the power electronics is directed to the heater core to facilitate heating of an airflow passing thereby.
