Abstract: A thermoelectric assembly is disclosed, the assembly having a cold side and a hot side, where each of the hot side and cold side comprises a fan sink. Thermoelectric modules may be between the hot side and cold side and arranged in one circuit or multiple parallel circuits, and in direct thermal contact with both the hot side and the cold side. Each of the hot side and cold side has an air intake direction and an exhaust direction.
Abstract: A thermal interface material is configured for use with an electronic device for transferring heat between heat generating components and heat removing components of the electronic device. The thermal interface material generally includes a first material (e.g., a gap filler, etc.) incorporating a contact resistance reducing material. The contact resistance reducing material operates to fill interstitial voids of surfaces of components in which the first material is installed to thereby reduce surface contact resistance between the first material and the component surfaces. The contact resistance reducing material may be applied to one or more side surfaces of the first material. Or, alternatively, the contact resistance reducing material may be blended in the first material.
