VARIABLE HEAT CONDUCTOR

摘要

A method and apparatus for a variable heat conductor that is able to increase heat conduction capacity based on operating temperature. The variable heat conductor is to be positioned between an electronic device and a heat sink to facilitate cooling of the electronic device. During cold start-up of the electronic device, the variable heat conductor acts as a thermal isolator, causing the electronic device to warm more quickly following the cold start-up. The variable heat conductor may fully conduct heat at higher temperatures that are at or above a desired temperature set-point.

主权项

1. A variable heat conductor, comprising:
a first major body being made from a first material; a second major body contacting the first major body, the second major body being made from the first material; and an expansion material being anchored to the first major body, a distal end of the expansion material and an inner surface of the second major body defining a gap, the expansion material being made from a second material, the second material having a higher rate of thermal expansion than the first material.
