Combination heatsink and battery heater for electronic devices
First Claim
1. An audio/video (A/V) recording and communication device, comprising:
- a camera;
a printed circuit board (PCB);
one or more infrared (IR) illuminators coupled to a first surface of the PCB and configured to illuminate a field of view of the camera with IR light;
a thermally conductive sheet having a first portion coupled to a second surface of the PCB and a second portion extending from the PCB; and
a rechargeable battery thermally coupled to the one or more IR illuminators through the thermally conductive sheet such that heat dissipation of the one or more IR illuminators warms the rechargeable battery.

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.
