Nvidia tab tom hloov cov gaskets ntawm nws cov chips: qhov kev sib ntaus sib tua tom ntej hauv thermal tsim yog qhov sib txawv me me ntawm millimeters ntawm cov nti thiab cov phaj txias.

Pib nrog Rubin hloov mus rau graphite thermal pads, cia peb tham txog vim li cas cov ntaub ntawv thermal interface tau dhau los ua qhov tseem ceeb.

Xyoo 2026, AI nti txias tau hloov pauv peb txoj kev nkag siab. Ua ntej, cov kev cai "conservative" NVIDIA tshaj tawm tias nws Vera Rubin platform yuav siv 45℃dej sov ua kua txias- cov chaw zov me nyuam tsis tas yuav tsum yog lub thawv dej khov. Tom qab ntawd, cov khoom siv saw hlau tau lees paub tias tus qauv Rubin version (TDP 1800-2000W) tso tseg cov hlau ua kua hauv feeb kawg ua ntej ntau lawm, hloov tag nrho rau cov thermal conductivity graphite pads. Tsuas yog Ultra saum toj kawg nkaus - ntawm -- kab version (2500–2850W) khaws cov kua hlau ua kua thiab lub microchannel txias phaj.

Saib ntawm ob qhov xwm txheej no ua ke nthuav tawm cov teeb liab tseem ceeb dua: raws li ib qho - daim npav siv hluav taws xob tau nce los ntawm 700W rau H100 rau qib 2000W, lub fwj hauv cov cua sov tsis yog "txawm hais tias lub tshuab hluav taws xob tuaj yeem ua kom txias," tab sis nyob rau hauv thaj tsam microscopic ntau dua - qhov sib cuam tshuam ntawm cov nti thiab kaum ntawm cov phaj txias. Cov kua dej txias tshem tawm cov cua sov los ntawm lub phaj txias, tab sis cov cua sov ua ntej yuav tsum muaj peev xwm "sau" lub phaj txias. Tsis muaj teeb meem npaum li cas ntawm cov nti thiab cov phaj txias, nyob rau hauv kev nthuav dav, lawv yog txhua qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob

Vera Rubin (tus qauv version) muaj TDP ntawm 1800-2000W, thiab ua ntej kev tsim khoom loj, nws tau tso tseg cov hlau ua kua thiab hloov nws nrog graphite -raws li thermal pads;

Ultra sab saum toj- ntawm-- kab version muaj TDP ntawm 2500-2850W, khaws cov kua hlau + microchannel txias phaj, thiab nkag mus rau ntau lawm hauv Q3.

-Tau los ntawm cov ntawv tshaj tawm pej xeem

Qhov no 1-millimeter battlefield yog cov khoom siv thermal interface (TIM). Cov kev xav tau rau cov ntaub qhwv ntsej yog qhov nruj heev: ceev conductivity- thermal conductivity yuav tsum ua raws li cov nti lub zog ceev; compactness-mos txaus thiab tsawg- kev ntxhov siab los sau cov npoo tsis sib xws yam tsis ua rau lub nti; thiab ruaj khov-nyob rau hauv cov khoom siv hluav taws xob siab, cov roj teeb lub zog tshiab, thiab cov chaw nres tsheb 5G, kev rwb thaiv tsev thiab nplaim hluav taws yog qhov tsawg kawg nkaus, tsis muaj nyiaj tshwj xeeb. Qhov no yog qhov tseeb vim li cas peb tsim DP series. Shengtong Qiyuan tsis muaj ib qho, universally siv thermal ncoo; Hloov chaw, peb tau tsim cov khoom tiav ntawm cov khoom siv thermally conductive silicone pads npog cov qib sib txawv, tso cai rau cov engineers xaiv tus qauv tsim nyog rau lawv cov kev xav tau, tsis yog siv txhua yam muaj.

Shengtong Qiyuan High Thermal Conductivity Series Silicone Pads

Peb Qhov Sib txawv ntawm Peb thiab Cov Txheej Txheem Thermally Conductive Silicone Pads
Qhov txawv 1: Thermal conductivity ranges ntawm 1.5 mus rau 25 W / m·k, nrog 17 qauv nyob rau hauv ib tug series.

Los ntawm DP150 mus rau DP2500: Standard range 1.5–5.0, siab conductivity 6.0–10.0, ultra-siab conductivity 12/15/18, thiab flagship DP2500 ua tau 25 ± 1 W / m·k. Tag nrho cov qauv yog sib koom ua ke raws li DP-Pad series, nrog thermal conductivity cross{15}}validated raws li ASTM D5470 thiab ISO 22007-2 tus qauv. Txoj haujlwm hloov kho dua tshiab los ntawm cov pa hluav taws xob ua kom sov mus rau ultra- lub zog siab yam tsis tas yuav hloov cov neeg xa khoom lossis rov- cov ntaub ntawv xeem. Thickness tuaj yeem txiav txim siab txog 20mm, thiab txiav thiab tuag- txiav tau txais kev txhawb nqa. Composite fiberglass substrate, ib leeg / ob npaug-sided silicone backing, los yog nplaum rov qab tuaj yeem kho raws li xav tau.

Qhov thib ob qhov sib txawv yog tias thaum ua tiav cov thermal conductivity, rwb thaiv tsev thiab nplaim hluav taws xob tsis cuam tshuam. Ib qho teeb meem hauv kev lag luam yog tias "siab thermal conductivity los ntawm tus nqi ntawm rwb thaiv tsev." Tus qauv DP ultra-siab thermal conductivity muaj peev xwm tiv taus ntau dua lossis sib npaug ntawm 6 KV / mm thiab lub ntim resistivity Ntau dua lossis sib npaug ntawm 10¹³ Ω·cm ntawm 12–18 W / m·k; tus qauv DP tus qauv muaj qhov siab dua tiv taus voltage Ntau dua lossis sib npaug rau 10 KV / mm. Txhua tus qauv ua tau raws li UL94 V-0 nplaim retardancy ntsuas thiab RoHS / REACH ib puag ncig yuav tsum tau ua. Nrog rau lub teb chaws tus qauv tshiab rau lub roj teeb kev nyab xeeb teeb tsa "tsis muaj hluav taws kub lossis tawg tom qab thermal runaway" raws li txoj kab liab uas yuav tsum tau ua, rwb thaiv tsev thiab nplaim hluav taws xob tsis zoo rau cov neeg siv khoom siv tsheb thiab hluav taws xob.

Qhov txawv 3: Ultra-mos thiab qis- kev ntxhov siab, tiv thaiv thiab txhawb lub nti.

Nrog lub hardness Shore 00 tsawg li 20-30, qhov saum npoo yog nplaum me ntsis, nthuav tawm cov compression resilience thiab qhov siab tshaj plaws elongation ntawm kev tawg ntawm 105%. Nws adheres zoo kawg nkaus rau cua sov- tsim cov qauv nrog cov tuab thiab qhov chaw tsis sib xws, tsis muaj qhov sib txawv ntawm huab cua. Tsawg deformation kev ntxhov siab tiv thaiv kev puas tsuaj rau cov nti thiab cov pob qij txha, thiab nws tsis tshua muaj kev tawg thiab tsis ua haujlwm txawm tias nyob rau lub sijhawm ntev thiab kub kub ua haujlwm thiab rov ua dua thiab rov ua dua.

Cov kauj ruam tom ntej nyob rau hauv tshav kub dissipation: cov ntaub ntawv interface.

High-cov ntawv ua haujlwm zoo thiab AI accelerator phaib, siab- cov khoom siv hluav taws xob muaj hluav taws xob, 5G lub hauv paus chaw nres tsheb thiab cov khoom siv kho qhov muag, OBCs thiab cov roj teeb hluav taws xob tshiab -nyob rau hauv cov xwm txheej no, DP series ua tib yam: tiv thaiv lub xeem ob peb feem kaum ntawm ib millimeter ua ntej lub phaj txias. NVIDIA kev hloov pauv ntawm Rubin gasket tsis yog qhov tsis paub, tab sis qhov kev xaiv meej engineering: thaum lub zog ntom ntom tau ua rau lub peev xwm ntawm huab cua txias thiab ua kua txias, qhov tseeb txiav txim siab qhov ntsuas kub ntawm qhov sib txawv yog thawj kauj ruam hauv kev tshem tawm cov cua sov los ntawm nti.

Yog tias koj tseem tab tom ntsuam xyuas cov kev daws teeb meem kub kub rau siab - fais fab modules, xav tiv tauj peb nrog koj daim duab kos duab. Qhia rau peb paub koj lub hwj chim, thickness, thiab rwb thaiv tsev uas yuav tsum tau, thiab peb yuav ncaj qha pab koj nrhiav tau qhov zoo tshaj plaws kev xaiv nyob rau hauv lub DP series -txawm koj xav tau, peb yuav muaj nws.
