Nrog rau kev sib koom ua ke ntawm cov servers, thiab ntau tus XEON blade servers thiab 1U servers los ntawm INTEL tau siv dav, thiab kev lag luam neeg rau zaub mov tau maj mam vam meej. Cov neeg rau zaub mov txias tau them nyiaj siab heev los ntawm cov tuam txhab heatsink thiab cov neeg siv khoom siv, yog li cov neeg ua haujlwm siab ua haujlwm heatsink plays lub luag haujlwm tseem ceeb hauv cov cua txias ntawm cov neeg rau zaub mov.

Txij li qhov zaus ntawm CPU siv los ntawm cov neeg rau zaub mov feem ntau yog siab, qee qhov muaj dual CPUs lossis ntau lub CPUs, ua ke nrog kev kub ceev SCSI hard disks thiab cov khoom siv hluav taws xob siab, cov khoom siv no feem ntau tsim kom muaj cua sov ntau, yog li huab cua. sai sai ua kub thiab ib tug high-efficiency kub dab dej yog ib qho tseem ceeb heev thiab tseem ceeb. Nyob rau tib lub sijhawm, thaum lub server ua haujlwm hauv 24 teev thiab cov kev xav tau cua txias yog qhov tseem ceeb heev, peb xav tau qee qhov kev ua haujlwm siab Server CPU heatsink los txhawb nws. kuj, qee chav khoos phis tawj yuav tsum ua kom nyob ntsiag to, yuav tsum tsis muaj kiv cua lossis lub suab nrov qis heatsink, yog li nws yog qhov ntsuas kua qaub rau lub server CPU kub dab dej.

Peb feem ntau faib cov neeg rau zaub mov kub dab dej los ntawm U xws li 1U server heat sink, 2U server heat sink, thiab lwm yam. Qhov tseeb, U yog ib chav tsev uas sawv cev rau qhov loj me ntawm cov neeg rau zaub mov, thiab yog cov ntawv luv rau chav tsev. Cov ncauj lus kom ntxaws yog txiav txim los ntawm Electronic Industries Association (EIA), ib pawg kev lag luam.

Yog vim li cas rau sizing tus neeg rau zaub mov yog kom cov neeg rau zaub mov loj kom haum rau ib tug hlau los yog txhuas rack. Muaj cov ntsia hlau qhov rau kho cov neeg rau zaub mov ntawm lub khib. Teem nws nrog cov ntsia hlau qhov ntawm lub server thiab kho nws nrog screws.

Cov qhov ntev tau teev yog qhov dav (482mm=19 ntiv tes) thiab qhov siab (ntau ntau ntawm 4.445cm) ntawm lub server. Racks uas ua tau raws li qhov yuav tsum tau muaj yog qee zaum hu ua "19-inch racks" vim tias lawv yog 19 ntiv tes dav. Daim duab saum toj no tseem tuaj yeem pom meej tias qhov chaw me me ntawm 1U server yog li cas.

Lub thickness yog raws li 44.5mm. 1U yog 44.5mm, 2U yog 2 zaug 1U yog 89mm (thiab lwm yam). Hauv lwm lo lus, lub npe hu ua "1U PC server" yog cov khoom lag luam nrog cov duab uas ua tau raws li EIA specification thiab thickness ntawm 44.5mm. Cov khoom tsim kom haum rau hauv 19-inch khib feem ntau hu ua khib servers.

Raws li cov cua kub dissipation nruab nrab, cov neeg rau zaub mov heatsink tuaj yeem muab faib ua ob hom tseem ceeb: cua txias neeg rau zaub mov kub dab dej thiab cov kua dej txias rau cov cua sov. Aluminium zipper fin cua sov yeeb nkab neeg rau zaub mov heatsink yog ib hom cua txias neeg rau zaub mov cua sov dab dej, thiab nws kuj yog cov feem ntau lug siv neeg rau zaub mov kub dab dej.

Zipper fin:Tooj thiab txhuas yog cov khoom siv ntau tshaj plaws rau lub dab dej kub tsim, tab sis vim li cas thiaj siv txhuas hlau los ua cov khoom siv ntawm lub zipper fin? Qhov tshwj xeeb kub muaj peev xwm kuj yog ib qho tseem ceeb parameter ntawm lub tshav kub dissipation nruab nrab, tab sis nws yog feem ntau overlooked. Ib qho nruab nrab nrog lub peev xwm kub tshwj xeeb yuav nqus los yog tawg ntau dua thaum nws nce lossis poob los ntawm 1 degree Celsius. Qhov tshwj xeeb kub muaj peev xwm ntawm tooj liab yog 386KJ / kg·K, thiab qhov tshwj xeeb kub muaj peev xwm ntawm txhuas yog 900KJ / kg·K, uas txhais tau hais tias txhuas muaj peev xwm dissipate cua sov ntau rau hauv chav tsev lub sij hawm; Tsis tas li qhov ceev ntawm tooj liab yog 8.96g / cm^3 thiab qhov ntom ntawm txhuas yog 2.7g / cm^3, aluminium zipper fin yog qhov hnyav dua li tooj liab fins; Ntxiv mus, tus nqi ntawm tooj liab yog qhov tseem ceeb tshaj 3 npaug ntawm tus nqi ntawm txhuas. Yog li ntawd yog vim li cas tus tsim lub dab dej kub nyiam xaiv aluminium los tsim cov zipper fins.

Cov kav dej kub:Lub thermal conductivity yog lub tshav kub hloov mus los ntawm ib cheeb tsam ntawm 1 square meter nyob rau hauv ib tug tej lub sij hawm ntawm lub sij hawm nyob rau hauv ib tug ruaj khov thaum tshav kub kub hloov tej yam kev mob, nrog ib tug kub ntawm qhov sib txawv ntawm 1 degrees Celsius ntawm ob sab ntawm ib tug thickness ntawm 1 m. Tej zaum koj yuav paub txog chav tsev, uas yog W/(m·K). Hom thermal roj kuj siv qhov no ua ib chav tsev. Qhov ntawd yog hais tias, qhov muaj zog thermal conductivity ntawm cov khoom, qhov kub ntau yog ua nyob rau hauv tib lub ntim tib lub sijhawm. Lub thermal conductivity ntawm ntshiab tooj liab yog 401 W / (m·K), thiab thermal conductivity ntawm ntshiab txhuas yog 237 W / (m·K). Yog li cov yeeb nkab kub thiab cov pedestal feem ntau yog ua los ntawm tooj liab rau kev hloov hluav taws xob sai.

Sinda Thermal yog tus kws tshaj lij thermal rau ntau yam ntawm cov dab dej kub uas tau siv dav hauv ntau lub lag luam, peb tsim thiab tsim txhua hom cua sov dab dej xws li aluminium extruded heat sink, txias forged heat sink, skived fin heat sink, boned fin heat sink, zipper fin heatsink thiab kua txias txias phaj, thiab lwm yam. Peb yog cov chaw tsim khoom ua kom sov lub dab dej rau cov neeg siv khoom thoob ntiaj teb. Yog tias koj muaj kev xav tau thermal thov hu rau peb, peb yuav muab kev pabcuam zoo tshaj plaws thiab zoo tshaj plaws.
