Chifukwa khadi basking

Kwa ena eni makompyuta ndi vumbulutso lenileni la chakuti aliyense khadi zithunzi heats, onse apawokha ndi Integrated mu chipset kapena CPU.

Zachitikiranji zimenezi? Pazifukwa zina, khadi kanema akuthamanga ozizira? Onse chafotokozedwa kwambiri chabe: maziko a kanema ano zithunzi purosesa wapangidwa mamiliyoni makiyi a pakompyuta - transistors. Ngakhale mowa panopa aliyense wa iwo ndi negligible, phindu okwana ake ndi lalikulu.

Monga tikudziwa njira sayansi, ndime ya panopa kudzera wochititsa ndi kuwonjezeka kutentha kwa otsiriza. Zotsatira amapezeka kwambiri bwino pa mafurikwense Kumwambamwamba, amene chikuchitika mu makadi. Zimenezi zikhoza kupewedwa yekha ndi ntchito superconductors pa ziro mtheradi.

Choncho, ngati khadi kanema ndi mkangano, izo silimanena vuto.

Komabe, nthawi zambiri anauka pa maonekedwe nkhaniyi. Chifukwa nkhaniyo chimagwiritsidwa ziti? Chifukwa cha ichi ndi chakuti nthawi zina mwamphamvu kwambiri usavutike khadi, zimene ails mwini kompyuta.

Ndi anamanga- CPU mitundu palibe vuto - makono chachikulu dongosolo kuzirala mosavuta dissipate oposa 100 Watts mphamvu ikukhudzana zomwe ziri zoposa mokwanira. Kuwonjezera liwiro awo kangapo chipereka zikuluzikulu kalasi apawokha adaputala azamagetsi, kotero pafupipafupi ntchito ndi chiwerengero cha transistors singakwane kulenga katundu mkulu choposa Mwachangu a dongosolo yozizira. M'mawu ena, nthawi zambiri basks khadi zakunja pluggable mu zitsulo pa mavabodi lapansi.

Limodzi la mafunso ovuta kwambiri kuti sangayankhe ndendende ichi: "Kodi kutentha kwa khadi kanema imatengedwa kuti ndi wabwinobwino?". Zitha ziri kudziwa kutentha kololeka. Yabwino yothetsera - kupita webusaiti GPU Mlengi wa (osati makadi onse kanema) ndi malongosoledwe a chitsanzo yeniyeni kupeza phindu kutentha kololeka. Choncho m'pofunika kuganizira kuti alipo zatsopano yopanga wa transistors michenga yopangira zida zamagetsi Sangathe kulenga ziwiri zofanana mwamtheradi, kotero zipani zonse yaing'ono "kuwanditsa" chizindikiro Komabe, mkati mwa malire a cholakwika. Zimenezi zimabweretsa chakuti khadi limodzi akhoza kupitiriza ntchito pa madigiri 70, ndi ena ali yemweyo, kokha pa 60. N'chifukwa chake, ngati khadi mkangano, eni amagwiritsa zosiyanasiyana kutentha makadi awo mankhwala osiyanasiyana. Popeza malo amapanga deta Kutentha ndikhoza kunyengerera - kuphunzira ogwiritsa 3-4 ananena mfundo ndi kuwerengera pafupifupi. Ngati "katundu" ofunsira atatu azithunzi omwe tikunena (masewera kompyuta) Kutentha Kodi musalumphe madigiri 70, palibe kalipokalipo.

Zimayambitsa kutentha adzauka ochepa:

- kuipitsa kanema khadi koziziritsira fumbi. chakuti zigawo zonse kompyuta ayenera kutsukidwa ku fumbi 2-3 pa chaka, koma ulamuliro izi kawirikawiri kukhala - choncho vuto;

- zimakupiza yozizira mabasi (ngati);

- mismatch chikalata magetsi voltages chofunika mfundo. Cheap kompyuta mphamvu mayunitsi okwanira ayenera m'malo zaka 1-2, chifukwa cha magawo awo otsika khalidwe pa nthawi anayamba "zimatengedwa", kusokoneza ntchito zigawo zikuluzikulu zonse;

- kuyanika wa phala matenthedwe. Pakati padziko zithunzi purosesa ndi heatsink pali mungafike chilengedwe - matenthedwe phala. Pa nthawi, wotaya katundu ndi ayenera m'malo;

- hardware wonongeka khadi kanema. Common chifukwa - kutupa electrolytic capacitor. Komanso, ena zitsanzo pa kampani NVIDIA (mwachitsanzo, 9600 GT) wotchuka chifukwa chakuti pambuyo chaka kapena miyendo iwiri wosweka soldered purosesa, zikubweretsa mavuto sizimadziwika - kuchokera kuwonjezeka kutentha, kuti wolephera wa Chip ndi;

- chifukwa odziwika - cholakwika makope otaya mpweya mkati dongosolo. Ngati dongosolo wagawo kuchotsa mbali chivundikiro Kutentha amakhalabe m'gawo zosiyanasiyana zovomerezeka, muyenera kuganizira mafani ndi zina.
