Tej hau kev kawm yuav ua li cas thov thermopaste

Yog xav paub yuav thov li cas thermal muab tshuaj txhuam, koj yuav tsum tau ob yam: ib tug me ntsis ntawm dawb lub sij hawm thiab ib qho Internet kev twb kev txuas. Lub ntiaj teb no network devoted mus no ib tug ntau ntawm cov khoom. Lawv sau tag nrho thiab sundry - los ntawm lub venerable computer geeks rau newbies uas xav vajhuam lawv tus kheej nyob rau hauv no txoj kev. Tshwj xeeb tshaj yog nyob rau hauv qhov teeb meem ntawm yuav ua li cas thov thermal roj, tsis muaj big deal. Txawm muaj tsis muaj neatness tsis muaj dab tsi phem yuav tshwm sim. Tsuas hais tias cov kub yuav tsum muaj ntau tshaj li qhov lawv txwv tsis pub yuav ua tau. Txawm tias, ntawm chav kawm, yog tias koj kis tau no muab tshuaj txhuam rau hauv lub motherboard, zoo li butter rau khob cij, tsis muaj dab tsi zoo yuav tuaj ntawm nws. Hais txog kev lam ua, peb yog referring rau tsim nyog txwv.

Feem ntau cov khoom devoted mus rau yuav ua li cas thov thermal roj, ib lub computer Cheebtsam teev. Nyob rau hauv qhov tseeb, lub Scope ntawm cov khov khoom tsis tsuas mus rau lub computer technology. Ntawm cov ntsiab ntawm cov hluav taws xob circuits muaj ob peb ntau npaum li cas thaum tshav kub kub. cua kub theem yog li ntawd zoo kawg uas tsis muaj kev siv ntawm ib tug kuj loj heev thaum tshav kub kub lub dab ntxuav tes teploraseivayuschego lawv heev yooj yim puas. Cov no yog cov ib co transistors, semiconductor diodes, kev circuits.

Nws yog tshwm hais tias tus denser rau qhov chaw hu ntawm lub radiator thiab lub txias neeg, qhov ntau zoo thaum tshav kub kub lub dab ntxuav tes. Nws hais ntxiv hais tias kom txhim kho lub tshav kub dissipation efficiency yog tsim nyog los tshem tawm tag nrho cov tsis xws luag nto kev kho mob: lawv yuav tsum tau txig ncaj, thaum uas tig mus, thiab tus cov lej quab yuam vector yuav sawv cev rau ib tug ncauj lus kom ntxaws perpendicular. Txawm li cas los, es tsis nyob rau hauv lub ntau lawm los ua xws li ib tug scrupulous ua hauj lwm, siv ib tug txawv tshuaj. Yog muaj ntaub ntawv ntawm qhov chaw ntawm lub khov loj nyob rau cov nuj nqis ntawm kev khiav compensating tsis xws luag. Nyob rau hauv qhov tseeb, peb yuav sib tham txog ib nrab thermal interface uas muaj thermal conductivity. Nyiam thermal roj yuav tsum muaj cov nram qab zog:

- mus rau cov hloov hauv lub tshav kub yog tsis zuj zus tshaj lub tshav kub tog cov khoom;

- yuav ua kua, tab sis nws tsis kis tau;

- muaj peev xwm "lo" mus rau lub chaw.

Nws yog ib qho yooj yim to taub hais tias lub thermal muab tshuaj txhuam manufacturers dabtsi, sim mus ua ke nyob rau hauv cov khoom opposite zog. Heev feem ntau muab tshuaj txhuam yog khaws zais cia, yog li kos mus rau lub chaw tsim tshuaj paus yog tsis yooj yim. Piv txwv li, thermal roj Zalman, nyob rau lub substrate yog zinc oxide, dissipates 1.2 W / m * K, tab sis Soviet CBT-8 xwb 0.7 units. Txawm li cas los, paub txog yuav ua li cas thov thermal muab tshuaj txhuam kom zoo, nws yog tau mus cuag tau efficiency ntawm lub tshav kub tog.

Ua li no, koj yuav tsum kom huv si ntxuav lub saum npoo ntawm yav dhau los thermal interface residues. Lw tus tuab fleecy ntaub. Ces raws li tus nplaim ib tug caij cua kub nrog ib tug nyias txheej ntawm muab tshuaj txhuam yog thov uniformly. Unoccupied chaw yuav tsum tsis txhob yuav, tab sis tsuas paug lub dhau heev lawm thaum tshav kub kub hloov lwm lub tsev (tom qab tag nrho, txawm qhov zoo tshaj plaws thermal muab tshuaj txhuam kev lub tshav kub zuj zus tshaj hlau). Ces koj yuav tsum ua tib zoo txuas tus nto thiab txhim kho lawv cov siab system. Yog li distortions yog tsis tsim nyog vim hais tias lawv txo cov kev sib cuag cheeb tsam thiab txo efficiency.
