Abstract: Aspects of the disclosure include a charge port having fast phase change material resolidification. An exemplary charge port can include a plug housing and a direct current terminal electrically coupled to the plug housing. A subassembly is coupled to the direct current terminal. The subassembly includes a cartridge filled with a phase change material and an enhancer. The enhancer includes a top portion and a bottom portion. The bottom portion is embedded within the phase change material and the top portion extends beyond the cartridge into ambient. The phase change material removes heat from the direct current terminal when charging. The enhancer removes heat from the phase change material for rapid resolidification.

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.

The heat pipe further includes a sorbent material coated onto the inner diameter surface of the tube, a first liquid contained within the bore, and a second liquid adsorbed by the sorbent material. The second liquid has a second boiling temperature that is higher than a first boiling temperature of the first liquid. The first liquid vaporizes into a first vapor, in response to the tube receiving heat from the electronic component and the first liquid reaching the first boiling temperature. The second liquid is desorbed from the sorbent material and vaporizes into a second vapor in response to the second liquid reaching the second boiling temperature.

Abstract: An adaptive radiant heating system regulates a climate inside a motor vehicle cabin having a seat for a vehicle occupant. The system includes radiant heating tiles arranged proximate the seat and powered by an energy storage device. The system also includes a first sensor for detecting a position of the occupant and generating a first signal indicative thereof. The system additionally includes a second sensor for detecting a temperature within the cabin and generating a second signal indicative thereof. The system furthermore includes an electronic controller in operative communication with the tiles and the first and second sensors, and configured to regulate the climate proximate the seat via selective control of the tiles. The controller is configured to receive the first and second signals and activate at least one of the tiles in response to the first and second signals, to thereby regulate the climate proximate the seat.

Abstract: A method of regulating thermal comfort of an occupant of a vehicle cabin uses a radiant heating tile powered via an energy storage device to generate thermal energy. The method also includes detecting the occupant's position via a position sensor and detecting the occupant's surface temperature and detecting a temperature of the tile via at least one temperature sensor. The method additionally includes determining, via an electronic controller, a rate of change of occupant's surface temperature and a difference between the tile temperature and the occupant's surface temperature relative to a predetermined temperature set-point. The method further includes regulating, via the electronic controller, a power input from the energy storage device to the tile in response to the determined rate of change of the surface temperature and the determined difference between the tile temperature and the occupant's surface temperature to thereby regulate the occupant's surface temperature.
