  • Patent number: 12041714
    Abstract: Various technologies described herein pertain to a sensor for an autonomous vehicle that includes one or more heat dissipation features. A sensor includes a top cover and a bottom cover, where the top cover and the bottom cover form at least a portion of a casing of the sensor. The sensor includes a coldplate, a first printed circuit board, and a second printed circuit board. A top side of the first printed circuit board is coupled to the top cover and a bottom side of the first printed circuit board is coupled to a top side of the coldplate. A top side of the second printed circuit board is coupled to a bottom side of the coldplate and a bottom side of the second printed circuit board is coupled to the bottom cover. Various features described herein enhance heat transfer from components on the first and second printed circuit boards.

  • Patent number: 11512730
    Abstract: The subject disclosure relates to a water-tight sealed stud assembly for high current applications. The water-tight sealed stud assembly can include a stud, a sealing ring, a sleeve, and a body. The stud may have a stud base and a thickened portion having an annular groove. The sealing ring may be disposed in the annular groove. The sleeve may be disposed circumferentially around the stud and made of a conductive material. The body may be disposed circumferentially around the sleeve and made of a non-conductive material. Systems and methods are also provided.

  • Patent number: 11191190
    Abstract: Two-phase cooling systems for autonomous driving super computers (ADSC) are described herein. In some examples, a two-phase cooling system can include a flow channel configured to circulate a flow; an evaporative heat exchanger comprising an inlet for receiving fluid from the flow channel and an outlet for releasing vapor generated from the fluid, the evaporative heat exchanger being configured to collect heat from components of the ADSC and transfer the heat away via the vapor released from the first outlet; a condensing heat exchanger configured to condense the vapor and remove latent heat associated with the vapor, the condensing heat exchanger comprising an inlet to the flow channel for receiving the vapor and an outlet to the flow channel for discharging fluid generated by condensing the vapor; and a pump configured to receive the fluid from the condensing heat exchanger and circulate the fluid to the evaporative heat exchanger.
