Heat dissipation material, method of manufacturing the same, and battery module including the heat dissipation material
View Patent ↗Provided are a heat dissipation material, a method of manufacturing the same, and a battery module including the same. The heat dissipation material according to an embodiment of the present disclosure may include: a plurality of foam pad members provided to be capable of buffering; and a graphite member configured to surround the foam pad member for heat conduction, wherein the graphite member is provided to surround the plurality of foam pad members, respectively.
1. A heat dissipation material comprising:
a plurality of foam pad members; and
a graphite member configured to surround the plurality of foam pad members, respectively, for heat conduction,
wherein side ends of the graphite member are attached to each other, and
wherein a portion of the graphite member is thermally compressed between two of the plurality of foam members.
2. The heat dissipation material of claim 1 , wherein the plurality of foam pad members are spaced apart from each other.
3. A method of manufacturing a heat dissipation material, the method comprising:
providing a plurality of foam pad members;
providing a graphite member for heat conduction to surround the plurality of foam pad members, respectively, wherein side ends of the graphite member are attached to each other; and
pressing a portion of the graphite member to thermally compress the portion between two of the plurality of foam members.
4. A battery module comprising:
a battery cell;
a heat dissipation plate configured to dissipate heat of the battery cell; and
a heat dissipation material of claim 1 , interposed between the battery cell and the heat dissipation plate.
5. The heat dissipation material of claim 1 , wherein the plurality of foam pad members includes three or more foam pad members.
6. The heat dissipation material of claim 1 , further comprising a thermo-bonding tape attached to the thermally compressed portion of the graphite member.
7. The method of manufacturing the heat dissipation material of claim 3 , further comprising attaching a thermo-bonding tape to the thermally compressed portion of the graphite member.
8. The heat dissipation material of claim 1 , wherein a cross-sectional shape of each of the plurality of foam pad members is a square shape or a triangle shape.
9. The method of manufacturing the heat dissipation material of claim 3 , further comprising forming a cross-sectional shape of each of the plurality of foam pad members into a square shape or a triangle shape.
