Abstract:
Apparatus for cooling an electronic device, said apparatus comprising:a first thermoelectric stage thermally coupled to said electronic device, said first thermoelectric stage having a first surface area for thermal dissipation;a second thermoelectric stage, said second thermoelectric stage having a second surface area for thermal absorption, wherein said second surface area is greater than said first surface area; anda thermal space transformer disposed between said first thermoelectric stage and said second thermoelectric stage, and thermally coupling said first thermoelectric stage to said second thermoelectric stage, wherein said thermal space transformer has a first thermal conductivity in an x-y axis plane transverse to a direction of primary heat flow through said first thermoelectric stage and said second thermoelectric stage, and a second thermal conductivity in a z axis direction parallel to said direction of primary heat flow through said first thermoelectric stage and said second thermoelectric stage, and wherein said first thermal conductivity is greater than said second thermal conductivity.
