5, Thaum tshav kub kub conduction daim kab xev
Thaum tshav kub kub conduction daim kab xev yog dav siv nyob rau hauv lub tshav kub conduction tsim ntawm cua sov li xws li CPU, hwj chim raj, module fais fab mov, thiab lwm yam. Lub tshav kub conduction daim kab xev siv cov roj hmab hluav taws xob ua hluav taws xob ua cov khoom siv hluav taws xob, thiab muaj lub siab-rhiab kub conduction nplaum rau ntawm ib lossis ob sab, uas yog kev ntseeg siab hauv adhesion thiab siab zog. Lub thermal conductive daim kab xev yog nyias thiab hloov tau, uas yooj yim heev kom haum rau saum npoo ntawm cov khoom siv thiab cov radiators. Lub thermal conductive daim kab xev kuj tuaj yeem hloov kho rau qhov kev hloov pauv ntawm qhov txias thiab kub kub kom ntseeg tau tias kev ua tau zoo thiab ruaj khov.
Daim ntawv thov:
Lub siab-rhiab nplaum rov qab nplaum ntawm thermal conductive daim kab xev muaj siab nplaum lub zog thiab zoo heev thermal conductivity. Nws tuaj yeem khi thiab kho cov cuab yeej thiab cov hluav taws xob kom ua tiav cov cua sov, rwb thaiv tsev thiab kho. Nws yog qhov tshwj xeeb tshaj yog haum rau lub sijhawm nrog kev sib koom ua ke siab, qhov chaw siv khoom me me, thiab kev txhim kho nyuaj. Nws yog cov khoom siv tsim nyog rau kev txo qhov ntim ntawm cov khoom siv cua sov dissipation thiab optimizing tsim.
txoj kev siv:
Ua tib zoo saib rau txoj kev ua haujlwm thaum sib txuas cov thermal conductive ob-rov qab nplaum daim kab xev. Nws yog nruj me ntsis txwv tsis pub kov saum npoo ntawm tes los yog lwm yam khoom uas tsis yog nplaum. Nws yog nruj me ntsis txwv tsis pub rov tev nws. Qhov saum npoo yuav tsum tau sib khi yuav tsum tau ceev kom huv si thiab qhuav. Feem ntau, ntxuav nws nrog cawv ua ntej siv kom tsis txhob cuam tshuam rau kev sib txuas ceev. Cov khoom siv pabcuam: paj rwb ntaub, muaj ntxhua khaub ncaws, hnab looj tes roj hmab.
Kauj Ruam 1: So saum npoo ntawm lub cuab yeej nrog ib daim ntaub tsis muaj lint.
Kauj Ruam 2: So lub ntsej muag ntawm lub cuab yeej nrog cov ntaub paj rwb uas ntub rau hauv cov tshuab ntxhua khaub ncaws kom tshem tawm cov roj stain; Tsis tas li ntawd, tsis txhob kov qhov chaw huv si thaum lub sijhawm teeb tsa.
Kauj Ruam 3: Tshem tawm cov yeeb yaj kiab tiv thaiv ntawm ib sab ntawm lub nraub qaum, thiab tsis txhob kov cov nplaum nplaum nrog koj cov ntiv tes.
Kauj Ruam 4: muab tshuaj txhuam rau ntawm qhov chaw ntawm lub cuab yeej, thiab nias nws maj mam los ntawm qhov nruab nrab ntawm qhov chaw sib txuas mus rau qhov chaw ib ntus rau tsib vib nas this kom paub meej tias daim kab xev ob-rov qab yog tag nrho 100 feem pua ​​​​ntawm kev sib cuag nrog cov cua kub dissipation. ntaus ntawv.
Kauj Ruam 5: Tshem tawm cov yeeb yaj kiab tiv thaiv ntawm lwm sab ntawm lub nraub qaum, thiab ua raws li tib txoj kev hauv Kauj Ruam 3 thiab Kauj Ruam 4 kom cov nplaum ntawm ob daim nplaum rov qab thiab cov nti ruaj khov.
6, Saj zawg zog thermal conduction ncoo
Saj zawg zog tshav kub conduction ncoo yog ib hom ntawm tshav kub conduction ncoo nrog thickness. Cov khoom siv hauv paus siv yog cov roj hmab silicone thiab ua npuas ncauj roj hmab. Cov roj hmab silicone yog tus cwj pwm los ntawm qhov zoo elasticity, thaum cov roj hmab ua npuas ncauj yog cov yam ntxwv ntawm qhov loj deformation ntau, zoo thermal conduction nyhuv thiab siab dua. Cov ntaub ntawv hloov pauv hloov pauv yog feem ntau yog siv los ua cov khoom ntim hauv qhov sib txawv loj los hloov cov cua sov. Nws feem ntau yog siv ntawm PCBs, nruab nrab ntawm PCBs thiab enclosures, nruab nrab ntawm cov khoom siv hluav taws xob thiab cov ntaub thaiv npog, lossis tsuas yog muab tso rau ntawm cov nti ua lub dab dej kub (qhov no, cov corrugated feem ntau yog siv). Cov thermal conductive muab tub lim nyob rau hauv cov thermal conductive ncoo yog feem ntau aluminium oxide hais los yog sib xyaw ntawm txhuas oxide, magnesium oxide thiab boron nitride. Lawv muaj cov thermal conductivity zoo thiab tuaj yeem tiv thaiv kev sib tsoo. Lawv yeej ua lub luag haujlwm insulating.
Daim ntawv thov: cov yeeb nkab kub sib dhos, RDROMTM nco module, CDROM cua txias, nruab nrab ntawm CPU thiab lub dab dej kub, txhua lub sijhawm uas yuav tsum tau hloov mus rau lub plhaub, chassis lossis lwm cov dab dej kub.
txoj kev siv:
Npaj cov khoom siv pabcuam: paj rwb ntaub, cov khoom siv ntxhua khaub ncaws, hnab looj tes roj hmab.
Kauj Ruam 1: So saum npoo ntawm lub cuab yeej nrog ib daim ntaub tsis muaj lint.
Kauj Ruam 2: So lub ntsej muag ntawm lub cuab yeej nrog cov ntaub paj rwb uas ntub rau hauv lub tshuab ntxhua khaub ncaws kom tshem tawm cov roj stain.
Kauj Ruam 3: Tshem tawm cov yeeb yaj kiab tiv thaiv ntawm ib sab ntawm lub nraub qaum, thiab tsis txhob kov cov nplaum nplaum nrog koj cov ntiv tes.
Kauj Ruam 4: Maj mam nias lub khawm hloov pauv hloov pauv kom ntseeg tau ruaj khov.
