English

The operation addresses heat removal from modern GPUs, whose heat flux density exceeds what conventional cooling solutions can handle. RED94 is developing a copper cooling core produced by additive manufacturing, in which the internal channel network is shaped through generative optimisation and verified by numerical simulation of flow and heat transfer.

Development runs as a loop of simulation, prototype, test-rig measurement and geometry correction, which makes it possible to compare predicted and actual thermal resistance and pressure drop at realistic coolant flow rates.

Expected effects: lower processor temperature at the same coolant flow rate and therefore more stable hardware operation; reduced energy consumption for cooling in data centres; transfer of additive copper manufacturing know-how into Slovenian production; new development jobs and international partner references.

Operacija naslavlja odvajanje toplote iz sodobnih grafičnih procesorjev, katerih gostota toplotnega toka presega zmogljivosti klasičnih hladilnih rešitev. RED94 razvija hladilno jedro iz bakra, izdelano z aditivno tehnologijo, pri katerem je notranja mreža kanalov oblikovana z generativno optimizacijo in preverjena z numerično simulacijo toka in prenosa toplote.

Razvoj poteka v zanki simulacija → izdelava prototipa → meritev na preizkusni progi → popravek geometrije, kar omogoča primerjavo napovedane in dejanske toplotne upornosti ter padca tlaka pri realnih pretokih hladilne tekočine.

Pričakovani učinki: nižja temperatura procesorja pri enakem pretoku hladilne tekočine in s tem stabilnejše delovanje strojne opreme; manjša poraba energije za hlajenje v podatkovnih centrih; prenos znanja o aditivni izdelavi bakrenih toplotnih komponent v slovensko proizvodno okolje; nova razvojna delovna mesta in mednarodne partnerske reference.
