  • Publication number: 20230253288
    Abstract: An integrated circuit device may include an integrated circuit die coupled to a substrate, and a porous material on the die or a thermal interface material and extending beyond the edges of the die and over the substrate. An integrated circuit system may include a substrate with a power supply and an integrated circuit die, such that a porous material on the die extends over the substrate beyond a footprint of the die. A porous material may be formed on and beyond an edge of a received integrated circuit die coupled to a substrate or a thermal interface material on the die.

  • Publication number: 20220240417
    Abstract: Technologies for dynamic cooling include a computing device having a multi-chip package including multiple dies and a cold plate coupled to the multi-chip package. Micro nozzle valves are coupled to fluid passage zones of the cold plate positioned adjacent to the dies, and are configured to control fluid flow into the fluid passage zones. The computing device reads a predetermined die junction temperature for each die, determines a current die junction temperature for each die, compares the predetermined die junction temperature to the current die junction temperature for each die, and determines a fluid flow rate for each die based on that comparison. The computing device controls the micro nozzle valves adjacent to each die based on the respective fluid flow rate. The dies may include processor cores, field-programmable gate arrays, memory devices, or other computer chips. Other embodiments are described and claimed.

  • Patent number: 10770372
    Abstract: A fluid routing device includes a fluid inlet, first vertical channels, a horizontal channel, a second vertical channel, and a fluid outlet. The first vertical channels are open to the fluid inlet. The horizontal channel is open to each of the first vertical channels. The first vertical channels are oriented to provide fluid coolant from the fluid inlet vertically down to the horizontal channel. The horizontal channel is open on one side such that fluid coolant in the horizontal channel directly contacts an apparatus attached to a bottom of the fluid routing device. The second vertical channel is open to the horizontal channel. The second vertical channel is oriented to provide fluid coolant vertically up away from the horizontal channel. The fluid outlet is open to the second vertical channel such that fluid coolant from the second vertical channel exits the fluid routing device through the fluid outlet.
