Cooling systems for unmanned aerial vehicles
An unmanned aerial vehicle (UAV) that includes: a front chassis defining an intake port; a rear chassis defining an exhaust port and providing a heatsink for the UAV; and a blower that is located immediately rearward of the intake port so as to facilitate unobstructed airflow through the intake port and into the blower. The blower is configured to direct air through the UAV along an airflow path that extends from the intake port to the exhaust port to thereby cool the UAV.
1 . An unmanned aerial vehicle (UAV) comprising:
front arms;
front propellers supported by the front arms;
rear arms;
rear propellers supported by the rear arms;
a chassis including:
a front chassis defining an intake port and supporting the front arms; and

a blower located immediately rearward of and positioned adjacent to the intake port so as to facilitate unobstructed airflow through the intake port and into the blower, wherein the blower is configured to direct air through the UAV along an airflow path that extends from the intake port to the exhaust port to cool the UAV, wherein the blower is configured to draw air into the intake port along a first axis and redirect the air along a second axis oriented in substantially orthogonal relation to the first axis, wherein the intake port and the exhaust port are spaced axially along an overall length of the UAV and define transverse cross-sectional dimensions extending in substantially perpendicular relation to the overall length of the UAV, wherein the first axis is oriented in substantially parallel relation to the overall length of the UAV.
2 . The UAV of claim 1 , wherein the heatsink is configured to redirect the air along a third axis oriented in substantially parallel relation to the first axis and in substantially orthogonal relation to the second axis.
3 . The UAV of claim 1 , further comprising:
at least one processor supported by the heatsink such that the heatsink distributes heat away from the at least one processor.
4 . The UAV of claim 3 , wherein the heatsink defines an internal chamber configured to receive the at least one processor such that the at least one processor is nested within the heatsink.
5 . The UAV of claim 3 , wherein the heatsink includes at least one cooling array with a plurality of fins extending outwardly from the heatsink, wherein the at least one processor is substantially aligned with the at least one cooling array.
6 . The UAV of claim 1 , further comprising:
a filter positioned about the intake port and configured to inhibit debris from entering the UAV.
7 . The UAV of claim 6 , wherein the filter includes a mesh material.
8 . An unmanned aerial vehicle (UAV) comprising:
a chassis defining an intake port located at a front end of the UAV and an exhaust port located at a rear end of the UAV such that the intake port and the exhaust port are spaced along an overall length of the UAV, wherein the chassis provides a heatsink for the UAV, wherein the intake port and the exhaust port define transverse cross-sectional dimensions extending in substantially perpendicular relation to the overall length of the UAV;
at least one processor supported by the heatsink such that the heatsink distributes heat away from the at least one processor; and
a blower located rearwardly of the intake port and configured to draw air into the intake port along a first axis extending in substantially parallel relation to the overall length of the UAV and redirect the air along a second axis oriented in substantially orthogonal relation to the first axis so as to direct the air across the heatsink and remove heat from the UAV through the exhaust port.
9 . The UAV of claim 8 , wherein the blower is positioned adjacent to the intake port.
10 . The UAV of claim 8 , wherein the heatsink includes a plurality of fins extending in substantially parallel relation to the second axis.
11 . The UAV of claim 10 , wherein the heatsink includes:
a first cooling array including a first plurality of fins; and
a second cooling array including a second plurality of fins.
12 . The UAV of claim 11 , wherein the first plurality of fins include a first material, and the second plurality of fins include a second material different than the first material.
13 . The UAV of claim 11 , wherein the at least one processor includes:
a first processor substantially aligned with the first cooling array; and
a second processor substantially aligned with the second cooling array.
14 . A method of cooling an unmanned aerial vehicle (UAV), the method comprising:
drawing air into the UAV through an intake port using a blower located adjacent to the intake port so as to facilitate unobstructed airflow through the intake port and into the blower;
redirecting airflow by approximately 90 degrees such that the air is directed across a heatsink in the UAV to distribute heat away from at least one processor secured to the heatsink; and
directing the air through an exhaust port to remove heat from the UAV, wherein the intake port and the exhaust port are spaced along an overall length of the UAV and define transverse cross-sectional dimensions extending in substantially perpendicular relation to the overall length of the UAV, wherein the air is drawn into the UAV along an axis extending in substantially parallel relation to the overall length of the UAV.
15 . The method of claim 14 , wherein drawing air into the UAV includes drawing the air through a filter positioned about the intake port and configured to inhibit debris from entering the UAV.
16 . The method of claim 14 , wherein redirecting airflow includes directing the air across the heatsink to distribute heat away from a first processor and a second processor.
17 . The method of claim 16 , wherein directing air across the heatsink includes:
directing the air across a first cooling array substantially aligned with the first processor; and
directing the air across a second cooling array substantially aligned with the second processor.
