Title: COMBINATION HEATSINK AND BATTERY HEATER FOR ELECTRONIC DEVICES
Abstract:
Some embodiments provide a novel method for harnessing the heat generated by one or more components (e.g., a set of IR LEDs) of an A/V recording and communication device in order to manage the temperature of one or more batteries of the A/V recording and communication device. Some aspects of the present embodiments raise the temperature of the battery in a cold weather without requiring any additional electrical power (e.g., without consuming any additional power for heating up the battery). In one aspect of the present embodiments, a thermally conductive sheet is coupled to a printed circuit board to which one or more IR LEDs are coupled. The thermally conductive sheet transfers the waste heat generated by the IR LEDs of the A/V recording and communication device to a rechargeable battery of the device.
