Pamene mapurosesa apakompyuta adathyola 1 GHz, kwakanthawi zimawoneka ngati palibe poti apite. Poyamba, zinali zotheka kuonjezera mafupipafupi chifukwa cha njira zatsopano zamakono, koma kupita patsogolo kwa mafupipafupi kunachepetsedwa chifukwa cha kukula kwa zofunikira zochotsa kutentha. Ngakhale ma radiator akulu ndi mafani nthawi zina sakhala ndi nthawi yochotsa kutentha ku tchipisi tamphamvu kwambiri.
Ofufuza ochokera ku Switzerland adaganiza zoyesa podutsa madzi kudzera mu kristalo wokha. Anapanga chip ndi dongosolo loziziritsa ngati gawo limodzi, lokhala ndi njira zamadzimadzi za pa-chip zoyikidwa pafupi ndi mbali zotentha kwambiri za chip. Chotsatira chake ndi kuwonjezereka kochititsa chidwi kwa ntchito ndi kutentha kwachangu.
Chimodzi mwavuto pakuchotsa kutentha kwa chip ndikuti nthawi zambiri chimaphatikizapo magawo angapo: kutentha kumasamutsidwa kuchokera ku chip kupita ku phukusi la chip, kenako kuchokera pamapaketi kupita ku heatsink, kenako kupita kumlengalenga (phala lotentha, zipinda za nthunzi, ndi zina zambiri). . atha kukhalanso nawo munjirayi.) Pazonse, izi zimachepetsa kuchuluka kwa kutentha komwe kungachotsedwe ku chip. Izi ndizowonanso pamakina ozizirira amadzimadzi omwe akugwiritsidwa ntchito pano. Zingakhale zotheka kuyika chip mwachindunji mumadzimadzi opangira thermally, koma chotsiriziracho sichiyenera kuyendetsa magetsi kapena kulowa muzochita zamakina ndi zida zamagetsi.
Pakhala pali ziwonetsero zingapo zakuzizira kwamadzimadzi pa-chip. Nthawi zambiri tikulankhula za kachitidwe komwe kachipangizo kokhala ndi mayendedwe amadzimadzi amaphatikizidwa pa kristalo, ndipo madziwo amawapopera. Izi zimathandiza kuti kutentha kuchotsedwe bwino kuchokera ku chip, koma kukhazikitsidwa koyambirira kunawonetsa kuti pali zovuta zambiri mumayendedwe ndi kupopera madzi mwanjira imeneyi kumafuna mphamvu zambiri - kuposa zomwe zimachotsedwa mu purosesa. Izi zimachepetsa mphamvu zamagetsi zamagetsi ndipo kuwonjezera apo zimapanga kupsinjika kwa makina owopsa pa chip.
Kafukufuku watsopano akupanga malingaliro owongolera magwiridwe antchito a makina oziziritsa pa-chip. Kuti mupeze yankho, makina oziziritsa amitundu itatu angagwiritsidwe ntchito - ma microchannel okhala ndi chosonkhanitsa chokhazikika (ma microchannel ophatikizidwa, EMMC). Mwa iwo, mawonekedwe amitundu itatu ndi gawo la njira yomwe ili ndi madoko angapo ogawa zoziziritsa kukhosi.
Ofufuzawa adapanga kachipangizo kakang'ono kophatikizana ndi monolithically integrated manifold microchannel (mMMC) pophatikiza EMMC mwachindunji pa chip. Njira zobisika zimamangidwa pansi pa malo omwe akugwira ntchito pa chip, ndipo chozizirirapo chimayenda molunjika pansi pa kutentha. Kupanga mMMC, choyamba, mipata yopapatiza yamakanema imakhazikika pagawo la silicon lokutidwa ndi semiconductor-gallium nitride (GaN); ndiye etching ndi mpweya wa isotropic umagwiritsidwa ntchito kukulitsa mipata ya silicon mpaka m'lifupi mwake; Pambuyo pake, mabowo omwe ali mu GaN wosanjikiza pamwamba pa mayendedwe amasindikizidwa ndi mkuwa. Chipchi chikhoza kupangidwa mumtundu wa GaN. Njirayi sikutanthauza dongosolo lolumikizana pakati pa osonkhanitsa ndi chipangizocho.
Ofufuzawa agwiritsa ntchito module yamagetsi yamagetsi yomwe imasintha kusintha kwapano kuti kuwongolera panopa. Ndi chithandizo chake, kutentha kumatuluka kuposa 1,7 kW / cm2 kumatha kukhazikika pogwiritsa ntchito mphamvu yopopa ya 0,57 W / cm2 yokha. Kuonjezera apo, dongosololi likuwonetseratu kutembenuka kwapamwamba kwambiri kusiyana ndi chipangizo chofananira chosakanizidwa chifukwa chosowa kudziwotcha.
Komabe, simuyenera kuyembekezera kuwoneka kwapafupi kwa tchipisi ta GaN ndi makina oziziritsa ophatikizika - pali zinthu zingapo zofunika zomwe ziyenera kuthetsedwa, monga kukhazikika kwadongosolo, malire a kutentha, ndi zina zotero. Ndipo komabe, iyi ndi sitepe yofunika kwambiri yopita ku tsogolo lowala komanso lozizira.
