International Classification:

H05K 7/20
F28F 21/06

US Classification:

361704, 165185

Abstract:

Various embodiments of an apparatus that simultaneously cools and thermally decouples adjacent electrically-driven devices in close proximity are provided. In one aspect, an apparatus comprises a first non-silicon heat sink and a first silicon-based heat sink disposed on the first non-silicon heat sink. The first silicon-based heat sink is configured to receive a first electrically-driven device on a first portion of the first silicon-based heat sink and to receive a second electrically-driven device on a second portion of the first silicon-based heat sink. The first silicon-based heat sink includes a first groove or a first opening between the first portion and the second portion such that a heat conduction path between the first electrically-driven device and the first non-silicon heat sink through the first silicon-based heat sink is shorter than a heat conduction path between the first electrically-driven device and the second electrically-driven device through the first silicon-based heat sink.

International Classification:

F28F 3/02

US Classification:

165185

Abstract:

A silicon-based thermal energy transfer apparatus that aids dissipation of thermal energy from a heat-generating device, such as an edge-emitting laser diode, is provided. In one aspect, the apparatus comprises a silicon-based base portion having a first primary surface and a silicon-based support structure. The silicon-based support structure includes a mounting end and a distal end opposite the mounting end with the mounting end received by the base portion such that the support structure extends from the first primary surface of the base portion. The support structure includes a recess defined therein to receive the edge-emitting laser diode. The support structure further includes a slit connecting the distal end and the recess to expose at least a portion of a light-emitting edge of the edge-emitting laser diode when the edge-emitting laser diode is received in the support structure.

International Classification:

H05K 7/20

US Classification:

429120, 16510411, 16510421, 361704

Abstract:

An apparatus using a phase-change material for thermal management in portable applications is described. In one aspect, the apparatus includes a phase-change material, a thermal reservoir, and a heat transport element. The thermal reservoir has a cavity therein to contain the phase-change material in the cavity. The heat transport element is made of a thermally conductive material. A first portion of the heat transport element traverses through the thermal reservoir and in contact with the phase-change material. A second portion of the heat transport element extends outside the thermal reservoir. Accordingly, at least part of the thermal energy from an object in contact with the heat transport element can be transported to the phase-change material via the heat transport element and be absorbed by the phase-change material as latent heat. The phase-change material may release at least part of the absorbed thermal energy at a later time.
