Pakatanga desktop processors kutyora 1 GHz, kwechinguva zvaiita sekunge pakanga pasina kwekuenda. Pakutanga, zvaikwanisika kuwedzera kuwanda nekuda kwemaitiro matsva ehunyanzvi, asi kufambira mberi kwemafafitera kwakazodzikira nekuda kwekukura zvinodiwa zvekubvisa kupisa. Kunyangwe maradiator makuru uye mafeni dzimwe nguva haana nguva yekubvisa kupisa kubva kune ane simba machipisi.
Vatsvakurudzi vanobva kuSwitzerland vakasarudza kuedza kuburikidza nekupfuura mvura kuburikidza nekristaro pachayo. Ivo vakagadzira chip uye kutonhora sisitimu sechinhu chimwe chete, ine on-chip fluid machani akaiswa padyo nenzvimbo dzinopisa dzechip. Mhedzisiro ndeyekuwedzera kunoshamisa kwekuita nekushanda kwekushisa kupisa.
Chikamu chedambudziko nekubvisa kupisa kubva pachip chip ndechekuti kazhinji inosanganisira matanho akati wandei: kupisa kunotamiswa kubva kune chip kuenda kune chip kurongedza, zvino kubva pakurongedza kuenda kune heatsink, uyezve kumhepo (inopisa paste, vapor chambers, etc. .inogonawo kuve nechekuita mukuita. Pakazara, izvi zvinogadzirisa huwandu hwekupisa hunogona kubviswa kubva pachiputi. Izvi ndezvechokwadiwo kune mvura yekutonhodza masisitimu ari kushandiswa parizvino. Zvingave zvichiita kuisa chip zvakananga mumvura inopisa inopisa, asi iyo yekupedzisira haifaniri kutungamirira magetsi kana kupinda mumakemikari ekugadzirisa nemagetsi emagetsi.
Pakatove nekuratidzira kwakati wandei kwe-on-chip liquid kutonhora. Kazhinji isu tiri kutaura nezve sisitimu umo mudziyo une seti yematanho emvura inosanganisirwa pakristaro, uye iyo mvura pachayo inopombwa nayo. Izvi zvinobvumira kupisa kuti kubviswe zvinobudirira kubva pachiputi, asi kutanga kushandiswa kwakaratidza kuti kune kudzvinyirira kwakawanda mumatanho uye kupomba mvura nenzira iyi kunoda simba rakawanda - rinopfuura rinobviswa kubva kune processor. Izvi zvinoderedza simba resimba rehurongwa uye nekuwedzera zvinogadzira njodzi yekushushikana kwemagetsi pane chip.
Tsvagiridzo nyowani inogadzira mazano ekuvandudza kushanda kwe-on-chip kutonhora masisitimu. Kuti uwane mhinduro, matatu-dimensional kutonhora masisitimu anogona kushandiswa - microchannels ine yakavakirwa-mukati muunganidzi (akaiswa manifold microchannels, EMMC). Mavari, matatu-dimensional hierarchical manifold chikamu chechiteshi chine zviteshi zvakawanda zvekugovera zvinotonhorera.
Vatsvakurudzi vakagadzira monolithically yakabatanidzwa manifold microchannel (mMMC) nekubatanidza EMMC zvakananga pane chip. Nzira dzakavanzwa dzakavakwa pasi penzvimbo dzinoshanda dzechip, uye inotonhorera inoyerera yakananga pasi pekupisa. Kugadzira mMMC, kutanga, mitsetse yakatetepa yemachaneli inoiswa pasilicon substrate yakavharwa ne semiconductor-gallium nitride (GaN); ipapo etching ine isotropic gasi inoshandiswa kuwedzera mapeji musilicon kune inodiwa chiteshi upamhi; Mushure meizvi, maburi ari muGaN layer pamusoro pematanho akavharwa nemhangura. Iyo chip inogona kugadzirwa muGaN layer. Iyi nzira haidi hurongwa hwekubatanidza pakati pemuunganidzi nemudziyo.
Vatsvakurudzi vakashandisa magetsi emagetsi module anoshandura alternating current kuti atungamirire ikozvino. Nekubatsira kwayo, kupisa kunoyerera kweanopfuura 1,7 kW/cm2 kunogona kutonhodzwa uchishandisa simba rekupomba re 0,57 W/cm2 chete. Uye zvakare, iyo sisitimu inoratidza zvakanyanya kutendeuka kwepamusoro pane imwe yakafanana isina kutonhorera mudziyo nekuda kwekushaikwa kwekuzvipisa.
Nekudaro, haufanirwe kutarisira kutaridzika kuri pedyo kweGaN-based chips ine yakasanganiswa yekutonhodza sisitimu - akati wandei akakosha nyaya dzichiri kuda kugadziriswa, sekugadzikana kwehurongwa, tembiricha yemiganhu, zvichingodaro. Uye zvakadaro, iyi inhanho yakakosha kumberi kune ramangwana rakajeka uye rinotonhora.
