Abstract

Systems and methods are disclosed for a fanless design of a rotating LIDAR system with integrated cleaning and cooling. An example system may include an enclosure including one or more electronics. The example system may also include a cooling element provided externally to the enclosure, the cooling element comprising one or more horizontal fins.

Claims (27)

1 . A LIDAR sensor head comprising:

an enclosure including one or more electronics;

a cooling element provided externally to the enclosure, the cooling element comprising one or more horizontal fins; and

an external housing configured to receive airflow from an environment external to the LIDAR sensor head through one or more openings and to expel airflow from the external housing through the one or more openings, wherein the cooling element is disposed within the external housing.

2 . The LIDAR sensor head of claim 1 , wherein the cooling element is affixed to an outer wall of the enclosure.

3 . The LIDAR sensor head of claim 1 , wherein the one or more openings comprise a first opening configured to receive the airflow from the environment external to the LIDAR sensor head and a second opening configured to expel the airflow within the external housing.

4 . The LIDAR sensor head of claim 1 , wherein the cooling element includes a plurality of horizontal fins, the plurality of horizontal fins being individually affixed to the enclosure.

5 . The LIDAR sensor head of claim 1 , wherein the cooling element further comprises one or more transparent windows or windows, the one or more transparent windows or windows being positioned in line with one or more emitters and one or more detectors of the one or more electronics inside the enclosure.

6 . The LIDAR sensor head of claim 1 , wherein the cooling element is cylindrical in shape, and is configured to rotate with a rotation of the LIDAR sensor head.

7 . The LIDAR sensor head of claim 1 , wherein the one or more horizontal fins are separated by a spacing of less than 5 millimeters.

8 . A LIDAR system comprising:

an enclosure including one or more electronics;

a cooling element provided externally to the enclosure, the cooling element comprising one or more horizontal fins; and

an external housing configured to receive airflow from an environment external to a LIDAR sensor head of the LIDAR system through one or more openings and to expel airflow from the external housing through the one or more openings, wherein the cooling element is disposed within the external housing.

9 . The LIDAR system of claim 8 , wherein the cooling element is affixed to an outer wall of the enclosure.

10 . The LIDAR system of claim 8 , wherein the one or more openings comprise a first opening configured to receive the airflow from the environment external to the LIDAR system and a second opening configured to expel the airflow within the external housing.

11 . The LIDAR system of claim 8 , wherein the cooling element includes a plurality of horizontal fins, the plurality of horizontal fins being individually affixed to the enclosure.

12 . The LIDAR system of claim 8 , wherein the cooling element further comprises one or more transparent windows or windows, the one or more transparent windows or windows being positioned in line with one or more emitters and one or more detectors of the one or more electronics inside the enclosure.

13 . The LIDAR system of claim 8 , wherein the cooling element is cylindrical in shape, and is configured to rotate with a rotation of the LIDAR system.

14 . The LIDAR system of claim 8 , wherein the one or more horizontal fins are separated by a spacing of less than 5 millimeters.

15 . A cooling element for a LIDAR system comprising:

one or more horizontal fins, wherein the cooling element is provided externally to an enclosure including one or more electronics, wherein the cooling element is disposed within an external housing, wherein the external housing is configured to receive airflow from an environment external to a LIDAR sensor head of the LIDAR system through one or more openings and to expel airflow from the external housing through the one or more openings, wherein the cooling element is disposed within the external housing.

16 . The cooling element of claim 15 , wherein the cooling element is affixed to an outer wall of the enclosure.

17 . The cooling element of claim 15 , wherein the one or more openings comprise a first opening configured to receive the airflow from the environment external to the LIDAR system and a second opening configured to expel the airflow within the external housing.

18 . The cooling element of claim 15 , wherein the cooling element includes a plurality of horizontal fins, the plurality of horizontal fins being individually affixed to the enclosure.

19 . The cooling element of claim 15 , wherein the cooling element further comprises one or more transparent windows or windows, the one or more transparent windows or windows being positioned in line with one or more emitters and one or more detectors of the one or more electronics inside the enclosure.

20 . The cooling element of claim 15 , wherein the cooling element is cylindrical in shape, and is configured to rotate with a rotation of the LIDAR sensor head.
