Abstract

An example sensor bracket assembly can include one or more cold plates forming a core bracket structure, wherein the core bracket structure and the one or more cold plates provide structural support for the sensor bracket assembly; a housing enclosing the core bracket structure; one or more sensor mounts for mounting one or more sensors on the sensor bracket assembly; and one or more attachment portions for attaching the sensor bracket assembly to a body of a vehicle.

First claim

What is claimed:

1. A sensor bracket assembly comprising:
one or more cold plates forming a core bracket structure, wherein the core bracket structure and the one or more cold plates provide structural support for the sensor bracket assembly;
one or more structural ribs or fins disposed against at least a portion of the one or more cold plates;
one or more sensor mounts for mounting one or more sensors on the sensor bracket assembly; and
one or more attachment portions for attaching the sensor bracket assembly to a portion of a body of a vehicle,
wherein the one or more cold plates are a plurality of cold plates, wherein each of the plurality of cold plates have an extruded shape and at least one of the plurality of cold plates is disposed adjacent to at least one other of the plurality of cold plates to form a corner, wherein at least one of the one or more structural ribs or fins are disposed in the corner, and wherein the one or more structural ribs or fins transfer heat from the one or more sensor to the at least one of the plurality of cold plates.

2. The sensor bracket assembly of claim 1 , further comprising:
one or more thermal spreaders disposed adjacent to at least one of the one or more cold plates.

3. The sensor bracket assembly of claim 1 , wherein the one or more cold plates have internal flow channels for a cooling liquid, wherein the internal flow channels are in contact with a pump configured to circulate the cooling liquid.

4. The sensor bracket assembly of claim 3 , wherein the internal flow channels are in thermal contact with at least one of a heat exchanger, a fin stack in contact with a fan, or a liquid cooling loop.

5. The sensor bracket assembly of claim 4 , wherein the at least one of the heat exchanger, the fin stack in contact with the fan, or the liquid cooling loop is in thermal contact with a vehicle cooling liquid loop associated with the vehicle.

6. A vehicle comprising:
a vehicle body; and
a sensor bracket assembly attached to the vehicle body, the sensor bracket assembly comprising:
one or more cold plates forming a core bracket structure, wherein the core bracket structure and the one or more cold plates provide structural support for the sensor bracket assembly;
one or more structural ribs or fins disposed against at least a portion of the one or more cold plates;
one or more sensor mounts for mounting one or more sensors on the sensor bracket assembly; and
one or more attachment portions for attaching the sensor bracket assembly to a portion of the vehicle body,
wherein the one or more cold plates are a plurality of cold plates, wherein each of the plurality of cold plates have an extruded shape and at least one of the plurality of cold plates is disposed adjacent to at least one other of the plurality of cold plates to form a corner, wherein at least one of the one or more structural ribs or fins are disposed in the corner, and wherein the one or more structural ribs or fins transfer heat from the one or more sensor mounts to the at least one of the plurality of cold plates.

7. The vehicle of claim 6 , further comprising:
one or more thermal spreaders disposed adjacent to at least one of the one or more cold plates.

8. The vehicle of claim 6 , wherein the one or more cold plates have internal flow channels for a cooling liquid, wherein the internal flow channels are in contact with a pump configured to circulate the cooling liquid.

9. The vehicle of claim 8 , wherein the internal flow channels are in thermal contact with at least one of a heat exchanger, a fin stack in contact with a fan, or a liquid cooling loop.

10. The vehicle of claim 9 , wherein the at least one of the heat exchanger, the fin stack in contact with the fan, or the liquid cooling loop is in thermal contact with a vehicle cooling liquid loop associated with the vehicle.

11. A method comprising:
forming a core bracket structure using one or more cold plates, wherein the core bracket structure and the one or more cold plates provide structural support for a sensor bracket assembly;
disposing one or more structural ribs or fins against the one or more cold plates;
forming one or more sensor mounts for mounting one or more sensors on the sensor bracket assembly; and
forming one or more attachment portions for attaching the sensor bracket assembly to a portion of a body of a vehicle,
wherein the one or more cold plates are a plurality of cold plates, wherein each of the plurality of cold plates have an extruded shape and at least one of the plurality of cold plates is disposed adjacent to at least one other of the plurality of cold plates to form a corner, wherein at least one of the one or more structural ribs or fins are disposed in the corner, and wherein the one or more structural ribs or fins transfer heat from the one or more sensor mounts to the at least one of the plurality of cold plates.

12. The method of claim 11 , further comprising:
disposing one or more thermal spreaders adjacent to at least one of the one or more cold plates.

13. The method of claim 11 , wherein the one or more cold plates have internal flow channels for a cooling liquid, wherein the internal flow channels are in contact with a pump configured to circulate the cooling liquid.

14. The method of claim 13 , wherein the internal flow channels are in contact with at least one of a heat exchanger, a fin stack in thermal contact with a fan, or a liquid cooling loop.
