An integrated thermal management system for fuel cell mobility vehicles, may include a hydrogen tank configured to store hydrogen supplied to a fuel cell stack, a first turbine rotated by the pressure of the hydrogen discharged from the hydrogen tank, a refrigerant circulation line configured such that a refrigerant circulates therealong and a compressor, a condenser, an expansion valve and an evaporator are provided thereon, a second turbine mounted in the refrigerant circulation line and rotated by the high-pressure refrigerant discharged by the compressor, and a blower configured to pressurize ambient air using the rotation force of the first turbine, the second turbine or an electric motor and to supply the pressurized ambient air to an indoor air conditioning unit or the fuel cell stack.

Integrated thermal management system for fuel cell mobility vehicles

An air conditioning system for electric vehicles reduces a thermal load endured by the air conditioning system using desiccant-coated heat exchangers and improves energy efficiency using waste heat resulting from cooling of an electronic device when the desiccant-coated heat exchanger is regenerated.

Air conditioning system for electric vehicles

Disclosed herein is an electric power and thermal management system in which, when a shaft is rotated due to an operation of a power part, generation of electric power and a circulation of a fluid are performed together so that the generation of the electric power and a circulation structure of oil are integrated, and thus a layout can be reduced, and a structure can be simplified. In addition, in a state in which the generation of the electric power and the circulation structure of the oil are integrated, a circulation amount of the oil is adjusted according to an angle of an inclined plate constituting a pumping mechanism so that an oversupply of the oil to parts through which the oil is circulated can be prevented.

Electric power and thermal management system

An oil dispersion system uses an actuator for propellers and includes a pumping device that circulates oil when a driving motor is operated to drive a propeller, whereby the propeller and an oil circulation structure are integrated, and a circulation amount of oil is adjusted based on an angle of a swash plate of the pumping device when the driving motor is operated in order to drive the propeller, thereby controlling a supply of oil to no more than that required by oil-using parts.
