Abstract
Disclosed herein are implementations of a cooling apparatus for use with a battery or battery pack. The battery may be a lithium-ion battery, and the battery pack may be two or more lithium-ion batteries. A cooling apparatus may include a heatsink. The heatsink may have a clearance portion configured to allow expansion of the lithium-ion battery. The cooling apparatus may include a metal plate coupled to the heatsink. The heatsink may be configured to contact the battery on at least three sides.
Claims20
An apparatus for cooling a battery, the apparatus comprising:
- a heatsink configured to absorb heat from the battery and contact the battery on at least three sides, the heatsink comprising a flange portion configured to hold the battery, wherein the flange portion creates an opening configured to allow expansion of the battery in a thickness direction upon heating of the battery;
- a thermally conductive elastomer comprising a base and a raised portion, wherein the base is in contact with the flange portion and the raised portion is configured to contact with the battery;
- and
- a metal plate coupled to the thermally conductive elastomer.
An apparatus for cooling a battery, comprising:
- a heatsink configured to contact at least three sides of the battery and to dissipate heat from the battery, the heatsink comprising a flange portion that is configured to define a clearance on a free side of the battery, wherein the clearance is configured to allow the battery to expand;
- a thermally conductive elastomer configured to exert a force against the battery such that the heatsink maintains contact with the at least three sides of the battery, the thermally conductive elastomer comprising:
- a raised portion that is disposed at least partially within the clearance and is configured to contact the battery, and
- a base contacting the flange portion of the heatsink;
- and
- a plate contacting the base of the thermally conductive elastomer.
An apparatus configured to cool a battery, comprising:
- a heatsink configured to contact sides of the battery and absorb heat from the battery, the heatsink including a flange portion that creates an opening configured to allow expansion of the battery upon heating of the battery;
- and
- a thermally conductive elastomer configured to exert a force against the battery such that the heatsink maintains contact with the sides of the battery, the thermally conductive elastomer comprising:
- a raised portion that is configured to contact the battery and to deform to allow the expansion of the battery, and
- a base that contacts the flange portion.
