Integrated cooling solution for spinning sensors
This technology relates to a system for cooling sensor components. The cooling system may include a sensor which has a sensor housing, a motor, a main vent, and a side vent. Internal sensor components may be positioned within the sensor housing. The motor may be configured to rotate the sensor housing around an axis. The rotation of the sensor housing may pull air into an interior portion of the sensor housing through the main vent, and the air pulled into the interior portion of the sensor housing may be exhausted out of the interior portion of the sensor housing through the side vent.
1 . A system for cooling sensor components, the system comprising:
a sensor including:
a sensor housing;
a main vent defined on the sensor housing;
a side vent defined on the sensor housing; and
one or more guide blades mounted in an interior portion of the sensor housing and near the main vent, wherein the one or more guide blades lie in one or more respective planes that each extend radially outward from an axis; and
a motor configured to rotate the sensor housing and the one or more guide blades around the axis,
wherein the rotation of the sensor housing pulls air into the interior portion of the sensor housing through the main vent,
wherein the rotation of the one or more guide blades moves the air away from the main vent to other portions of the interior of the sensor housing, and
wherein the air pulled into the interior portion of the sensor housing is exhausted out of the sensor housing through the side vent.
2 . The system of claim 1 , wherein the one or more guide blades are fixed relative to the housing.
3 . The system of claim 1 , wherein the one or more guide blades are configured to force the air pulled into the interior portion of the sensor housing radially outward from the axis.
4 . The system of claim 3 , wherein the motor is configured to rotate the one or more guide blades in order to force the air pulled into the interior portion of the sensor housing radially outward from the axis.
5 . The system of claim 1 , wherein the one or more guide blades are straight.
6 . The system of claim 1 , wherein the motor is configured to rotate the one or more guide blades and the sensor housing at a same rate.
7 . The system of claim 1 , wherein a change in pressure the one or more guide blades produce is based on a position of the one or more guide blades relative to the axis.
8 . The system of claim 1 , wherein the main vent is positioned on a top portion of the sensor housing.
9 . The system of claim 8 , wherein the side vent is positioned on a side wall of the sensor housing closer to a base portion of the sensor housing than the top portion.
10 . The system of claim 1 , wherein the main vent is positioned on a base portion of the sensor housing.
11 . The system of claim 10 , wherein the side vent is positioned on a side wall of the sensor housing closer to a top portion of the sensor housing than the base portion.
12 . The system of claim 1 , further comprising internal sensor components positioned within the sensor housing.
13 . The system of claim 1 , wherein an effectiveness of one or more guide blades for moving air from the axis is based on a position of the one or more guide blades relative to the axis.
14 . The system of claim 1 , wherein the sensor housing is in a shape of a frustum.
15 . The system of claim 12 , wherein the sensor housing includes a housing window.
16 . The system of claim 15 , wherein the housing window is configured to allow the internal sensor components to transmit and receive signals.
17 . The system of claim 1 , further comprising a vehicle.
18 . The system of claim 17 , wherein the sensor is mounted to a roof of the vehicle.
19 . The system of claim 1 , wherein the sensor housing further comprises a spoiler edge positioned in a leading position relative to the side vent when the sensor housing is rotating.
20 . The system of claim 15 , wherein the side vent is positioned such that air is exhausted past the housing window in order to prevent particle buildup thereon.
