Abstract

A protrusion 53 is shaped to protrude from a main body 51 toward a supporter non-contact part 23 so as to circumvent a supporter 30 . The protrusion 53 includes a protrusion heat transfer surface 55 which is a surface on the battery heat transfer surface 20 side (i.e., an upper side Y2). A heat conduction member 40 contacts with the supporter non-contact part 23 and the protrusion heat transfer surface 55.

First claim

What is claimed is:

1. A battery cooling structure comprising:
a battery;
a heat sink;
an insulating supporter provided between the battery and the heat sink and supporting the battery; and
an insulating heat conduction member provided between the battery and the heat sink;
the battery having a battery heat transfer surface which is a surface on the heat sink side,
the battery heat transfer surface including:
a supporter contact part with which the supporter contacts; and
a supporter non-contact part which is different from the supporter contact part and with which part the supporter does not contact,
the heat sink including:
a main body; and
a protrusion which is shaped to protrude from the main body toward the supporter non-contact part so as to circumvent the supporter,
the protrusion including a protrusion heat transfer surface which is a surface on the battery heat transfer surface side, and
the heat conduction member contacting with the supporter non-contact part and the protrusion heat transfer surface.

2. The battery cooling structure according to claim 1 , wherein,
the heat conduction member is disposed to be successive between a position between the protrusion heat transfer surface and the supporter non-contact part and a position between the main body of the heat sink and the supporter.
