  • Publication number: 20200051896
    Abstract: A semiconductor microcooler is fabricated by forming fins in a semiconductor substrate and forming a metal layer upon the fins. A stacked microcooler may be formed by stacking a plurality of semiconductor microcoolers. The microcoolers may be positioned such that the fins of each microcooler are aligned. One or more microcoolers may be thermally connected to a surface of a coolant conduit that is thermally connected to an electronic device heat generating device, such as an integrated circuit (IC) chip, or the like. Heat from the electronic device heat generating device may transfer to the one or more microcoolers. A flow of cooled liquid may be introduced through the conduit and heat from the one or more microcoolers may transfer to the liquid coolant.

  • Publication number: 20190346215
    Abstract: A heat sink includes a threaded rod. The spacing between a first fin and a second fin of the heat sink may be adjusted by the threaded rod. The threaded rod includes a first portion and a second portion. The first portion may engage with the first fin and a second portion may engage with the second fin. The thread pitch of the first portion and the second portion may differ. For example, the pitch of a first knurl of the threaded rod may be smaller than the pitch of a second threaded knurl of the threaded rod. The spacing of the heat sink fins may be adjusted based upon the current operating conditions of the electronic device to maintain an optimal temperature of a heat generating device during device operation.

  • Patent number: 10088244
    Abstract: A heat sink includes a heat sink base/riser, a first fin, and a second fin. The spacing between the base/riser and the first fin and the second fin, restively, may be adjusted by rotating a threaded rod. The threaded rod includes a first threaded knurl that is engaged with the first fin and a second threaded knurl that is engaged with the second fin. The thread pitch of the first threaded knurl and the second threaded knurl may differ. For example, the pitch of the first threaded knurl may be smaller than the pitch of the second threaded knurl if the first fin is located nearest the heat sink base/riser relative to the second fin. The spacing of the heat sink fins may be adjusted based upon the current operating conditions of the electronic device to maintain an optimal temperature of a heat generating device during device operation.
