System and method for directing an airflow into a sensor enclosure
摘要
說(shuō)明書
Described herein are systems and methods for heat exchange and cooling for a sensor enclosure on a vehicle, for example, a LiDAR sensor enclosure mounted on a roof of an AV, that are more convenient and reduce a computational burden on the sensor system, such as an AV sensor system. Various embodiments of the present disclosure provide a cooling system disposed on a vehicle. The cooling system may comprise an enclosure comprising a vent at a base of the enclosure. The enclosure may house one or more sensors and a fan. The cooling system may comprise a deflector connected to the enclosure. The deflector may be configured to channel an airflow and direct the channeled airflow into the vent of the enclosure. The deflector may increase an efficiency or an amount of air flowing into the enclosure.
In some embodiments, the deflector may further comprise a groove in which the deflector moves up and down.
In some embodiments, the one or more sensors may be configured to determine a speed of the vehicle, an internal temperature of an enclosure, an external temperature, and a wind speed. In some embodiments, the controller may be configured to adjust a height of the deflector by moving the deflector up or down in the groove, based on the speed of the vehicle, the internal temperature of the enclosure, the external temperature, a difference between the internal temperature of the enclosure and the external temperature, or the wind speed.
In some embodiments, the controller is further configured to adjust a rotation speed of the fan based on the height of the deflector.
In some embodiments, the controller is configured to operate the deflector in an inactive mode in which the deflector is fully embedded in the groove and an active mode in which the deflector extends above the groove.
