Abstract
An electronic speed controller (ESC) assembly for an unmanned aerial vehicle includes a first ESC for driving a first motor, a second ESC for driving a second motor, and a heat sink assembly disposed between the first ESC and the second ESC. The first motor is configured to drive an upper propeller to generate a lift, and the second motor is configured to drive a lower propeller to generate a lift. The first ESC and the second ESC are alternately disposed. The heat sink assembly includes a heat sink main body, and a thermally conductive metal and a heat dissipation pipe disposed on the heat sink main body. The thermally conductive metal is connected to the heat dissipation pipe. The first ESC and the second ESC are respectively in contact with the thermally conductive metal on the heat sink main body to transfer generated heat to the thermally conductive metal.
