Abstract
In one embodiment, a thermal device includes a sealed housing that defines an interior space, a liquid-attracting element provided on one side of the interior space, a liquid-repelling element provided on another side of the interior space opposite to the liquid-attracting element, and a liquid provided within the interior space.
Claims20
A thermal device comprising:
- a sealed housing that defines an interior space maintained in a vacuum;
- a sheet-like porous element that substantially fills the interior space;
- a hydrophobic portion of the sheet-like porous element that extends from a first side of the sheet-like porous element to a first depth across a thickness of the sheet-like porous element;
- a hydrophilic portion of the sheet-like porous element that extends from a second side of the sheet-like porous element to the hydrophobic portion of the sheet-like porous element;
- and
- a fluid within a void space of the sheet-like porous element.

An object comprising:
- a thermal device comprising a sealed housing that defines an interior space;
- a porous element that substantially fills the interior space, the porous element comprising a hydrophobic portion and a hydrophilic portion, wherein the hydrophobic portion extends a distance from a first side of the porous element towards a second side of the porous element, and the hydrophilic portion extends from the second side to the hydrophobic portion;
- and
- a fluid within the interior space.
