Abstract
A self-heating thermal interface material (TIM) may be formed using heating components dispersed within the TIM. The heating components may produce heat when the TIM is compressed. The heating components may be formed from microcapsules and the microcapsules may contain exothermic reactants. The reactants may be isolated from contact within the microcapsule until a compressive force is applied.
Claims10
A method for creating a self-heating thermal interface material (TIM), the method comprising:
- selecting a TIM, the TIM having a first compliance at a first temperature, the TIM having a second compliance at a second temperature;
- forming at least one heating component, the at least one heating component producing heat when subjected to a compressive force, the heat produced by the at least one heating component transferring to the TIM;
- determining an amount of the at least one heating component sufficient to increase the temperature of an amount of the TIM, the increased temperature producing the second compliance;
- and
- dispersing the amount of the at least one heating component within the amount of the TIM.
