Abstract: A heat dissipation device for an electronics cooling system having an electronic component includes a housing that defines a chamber. The device further includes a first liquid, which is contained within the chamber and has a first boiling temperature. The device further includes a sorbent material immersed within the first liquid. The device further includes a second liquid, which is adsorbed by the sorbent material and has a second boiling temperature that is above the first boiling temperature. The first liquid vaporizes into a first vapor, in response to the first liquid reaching the first boiling temperature. The second liquid is desorbed from the sorbent material, in response to the second liquid and the sorbent material reaching a desorption temperature that is below the second boiling temperature. The second liquid vaporizes into a second vapor, in response to the second liquid reaching the second boiling temperature.

Abstract: A vehicle wheel assembly includes a vehicle wheel including a wheel body having a center. The vehicle wheel defines a plurality of openings arranged annularly around the center of the wheel body. The vehicle wheel assembly further includes a self-deployed wheel shutter system coupled to the vehicle wheel. The self-deployed wheel shutter system includes a hub plate, an annular rim disposed around the hub plate, and a plurality of shutter flaps. The shutter flaps are movable relative the vehicle wheel between an extended position and a retracted position. In the extended position, the shutter flaps cover the openings of the vehicle wheel to preclude air from flowing through the vehicle wheel. When the plurality of shutter flaps are in the retracted position, the openings are exposed, allowing the air to flow through the openings of the vehicle wheel.

Abstract: A brake temperature monitoring system configured to monitor at least one of a rotor and hydraulic fluid of a brake mechanism for a vehicle. The system including a controller including a processor and an electronic storage medium, a vehicle velocity sensor, an ambient temperature sensor, and a pre-programmed module. The vehicle velocity sensor is configured to output a velocity signal to the processor. The ambient temperature sensor is configured to output an ambient temperature signal to the processor. The model is pre-programmed into the electronic storage medium, and is adapted to estimate the temperature of at least one of the rotor and the hydraulic fluid. The estimation is based on an ambient air temperature, and a pre-established relationship between a conductive heat transfer factor and a convective heat transfer factor. The convective heat transfer factor is a function of vehicle velocity.
