Abstract
This technology relates to a cooling system for reducing the amount of heat within a sensor housing. The system comprising a cold plate containing an interior liquid cooling channel containing a cooling fluid, a heat exchanger attached to the cold plate, and at least one fan configured to generate an air flow loop. The heat exchanger is configured to draw heat from the air flow loop and pass the drawn heat to the cold plate, which in turn, passes the drawn heat to the cooling liquid.
Claims20
A cooling system comprising:
- a sensor housing;
- a plurality of sensor components;
- a cold plate containing an interior liquid cooling channel containing a cooling fluid, wherein at least one of the plurality of sensor components is mounted on the cold plate, at least one of the plurality of sensor components is positioned in proximity to the cold plate, and the cold plate is configured to draw heat from the plurality of sensor components;
- a heat exchanger attached to the cold plate;
- and
- a plurality of fans configured to generate two air flow loops to reduce the heat within the sensor housing generated by the plurality of sensor components,
- wherein the cold plate includes a plurality of pass-throughs for allowing the two air flow loops to pass through the cold plate,
- wherein the heat exchanger is configured to draw heat from the two air flow loops and pass the drawn heat to the cold plate, which in turn, passes the drawn heat to the cooling fluid,
- wherein an interior of the sensor housing includes an upper portion, a lower portion, and a middle portion positioned between the upper portion and the lower portion, and a separating structure positioned between the upper portion and the middle portion, wherein at least one of the plurality of sensor components is mounted on the separating structure;
- wherein a first of the two air flow loops pulls air from the lower portion into the middle portion, and
- wherein a second of the two air flow loops pulls air from at least one of the middle portion or the upper portion into the lower portion.
