Abstract

Provided are a power receiving unit suppressing temperature rise of at least one of a coil and a capacitor, and a power supply system having the power receiving unit. The power receiving unit includes a coil and a capacitor body used for noncontactly receiving the power transmitted from the power supply device, and a receiving side case including therewithin a space housing the coil and the capacitor body. A pace K inside the receiving side case is wholly filled with heat conduction member.

First claim

What is claimed is:

1. A power receiving unit configured to be disposed at an underside of a vehicle and configured to noncontactly receive power transmitted from a power supply part disposed on the ground, the power receiving unit comprising:
a coil and a capacitor body used for receiving the power; and
a case including a main body made of material passing magnetism, and a cover made of material not passing magnetism, or made of resin and on which a magnetic shield plate is provided, and including a space located within the main body, the space housing the coil and the capacitor body,
wherein a part where the capacitor is at least arranged in the space within the case is filled with a heat conducting member,
wherein the heat conducting member is not air,
wherein the capacitor body is constituted of a circuit board and a plurality of capacitors mounted on the circuit board, and
wherein an entirety of the space within the case is filled with the heat conducting member such that the heat conducting member fills the entire space between the capacitor body and the main body and the entire space between the capacitor body and the cover.

2. The power receiving unit according to claim 1 , wherein the circuit board includes the heat conducting member.

3. A power supply system, comprising:
a power supply part disposed on the ground; and
a power receiving part disposed in the vehicle, the power receiving part noncontactly receiving power transmitted from the power supply part, wherein

the power receiving part includes the power receiving unit according to claim 1 .

4. A power supply system, comprising:
a power supply part disposed on the ground; and
a power receiving part disposed in the vehicle, the power receiving part noncontactly receiving power transmitted from the power supply part, wherein

the power receiving part includes the power receiving unit according to claim 2 .
