Title:
COIL UNIT AND NON-CONTACT POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2023051776
Kind Code:
A
Abstract:
To suppress, in a coil unit having a power transmission coil and a power reception coil, a temperature rise of a conductive shield caused by an eddy current loss, and to provide a non-contact power supply system which suppresses the temperature rise of the conductive shield.SOLUTION: A coil unit for non-contact power supply includes: a spirally wound coil; a magnetic shield provided to face the coil; and a conductive shield. The magnetic shield has a magnetic shield bottom face part provided to face the coil. The conductive shield includes: a conductive shield bottom face part provided along the opposite surface of the magnetic shield bottom face part to the surface facing the coil; and a conductive shield side face part configured to surround the peripheral part of the coil from the conductive shield bottom face part. A magnetic sheet is provided along the opposite surface to the surface facing the magnetic shield bottom face part of the coil.SELECTED DRAWING: Figure 1
