Cooling device for inductive charging of motor vehicles
The patent US12035512B2 describes a cooling device specifically designed for electromagnetic induction charging systems used in motor vehicles. The cooling device features a dual-shell housing that encloses an interior space, which contains both air and coolant paths that are fluidically separated. The design includes at least one heat exchanger where heat is transferred from the coolant to the air, effectively cooling the coolant. Additionally, the device incorporates fans positioned upstream of the heat exchangers to facilitate airflow through the system. The configuration allows for multiple air and coolant paths, enhancing the cooling efficiency and adaptability of the device.
Further claims detail the structural arrangement of the cooling device, including the use of multiple heat exchangers and fans that are arranged in a mirrored or V-shaped geometry. The design also includes integral components such as air filters, an equalizing receptacle for coolant management, and specific inlet and outlet paths for both air and coolant. The cooling device is integrated with an electromagnetic resonator, enabling effective cooling during the inductive charging process. The patent outlines various configurations and features that enhance the operational efficiency and maintenance of the cooling system, ensuring optimal performance in electric vehicle charging applications.
