Abstract
In some examples, a thermal control device includes a vapor chamber comprising a fluid to transport heat from a first portion of the vapor chamber to a second portion of the vapor chamber, and an isolation chamber adjacent the vapor chamber and fluidically isolated from the vapor chamber, the isolation chamber evacuated to a pressure less than atmospheric pressure to thermally isolate at least a portion of the vapor chamber.
Claims15
A thermal control device comprising:
- a vapor chamber comprising a fluid to transport heat from a first portion of the vapor chamber to a second portion of the vapor chamber;
- and
- an isolation chamber adjacent the vapor chamber and fluidically isolated from the vapor chamber, the isolation chamber evacuated to a pressure less than atmospheric pressure to thermally isolate at least a portion of the vapor chamber.
A method of making a thermal control device, comprising:
- evacuating an isolation chamber to remove fluid from the isolation chamber;
- filling a vapor chamber with a working fluid for transporting heat from a first portion of the vapor chamber to a second portion of the vapor chamber;
- and
- providing a layer between the vapor chamber and the isolation chamber, the layer fluidically isolating the isolation chamber from the vapor chamber.
