Abstract
An enhanced heat transposer comprised is of a vapor chamber. The surface of the vapor chamber that holds the fluid comprises an array of carbon nanotubes (CNTs) that are grown in a way that enables the fluid to come into maximum contact with the CNTs. The fluid evaporates in the sealed vapor chamber when it is in touch with a hot surface. The vapor comes in contact with a hollow pin-fin structure that provides additional surface area for vapor cooling and heat transfer. The condensed vapor then drops back into the fluid container, and the cycle continues.
Claims32
A thermal transposer, comprising:
- a substrate;
- a plurality of carbon nanotubes individually grown on a first surface of said substrate in an orientation that is substantially parallel to a desired heat transfer axis of said thermal transposer;
- an encapsulating structure attached to said substrate together forming a sealed vapor chamber, wherein said carbon nanotubes are located inside of said sealed vapor chamber;
- and,
- a vapor fluid contained within said vapor chamber.
A method for creating a thermal transposer comprising the steps of:
- individually growing a plurality of carbon nanotubes from a first surface of a substrate in an orientation substantially parallel to a desired heat transfer axis of said thermal transposer;
- forming an encapsulating structure;
- attaching said encapsulating structure to said substrate to form a vapor chamber that contains an array such that wherein said plurality of carbon nanotubes is contained therein;
- adding a vapor fluid to said vapor chamber;
- sealing said vapor chamber;
- and
- creating a desired level of vacuum in said vapor chamber.
