Ese imirongo ya Aluminiyumu itwikiriye irashobora gutanga EMI nziza yo gukingira mudasobwa ya AI?

Mudasobwa nini cyane ya AI ikora ku muvuduko ukabije w’isaha (GHz) hamwe n’igipimo kinini cy’inzibacyuho itanga amashanyarazi akomeye (EMI) hamwe na radiyo-interineti (RFI). Urusaku rwinshi rwo guhinduranya urusaku ruvuye muri kilowatt nyinshi zo gukwirakwiza amashanyarazi (PDUs) hamwe n’umuvuduko wihuse wa optique ya transiteri irashobora guhagarika byoroshye imiyoboro yerekana ibimenyetso byegeranye mugihe uruzitiro rufunze, insinga za kabili, hamwe nintera ya rack bidafunze hamwe nibikoresho byo gukingira neza.

Gukoresha imiyoboro ya aluminiyumu itwikiriye (0,05 mm - 0,3 mm) yerekana karuboni yuzuye yuzuye ya karubone cyangwa ibyuma byikubye hejuru itanga uburyo bwiza bwo gukingira (> 80 dB hejuru ya 100 MHz - 10 GHz), imbaraga zidasanzwe zo guhuza amashanyarazi, hamwe nuburyo bworoshye bwimiterere yimiterere yibisekuru bizaza bya AI.

Multi-Gigahertz Guhindura inshuro & Electromagnetic Kumeneka

Mudasobwa zigezweho za AI zipakurura ibihumbi n'ibihumbi byo hejuru ya TDP yo kubara, guhuza imiyoboro ya optique, hamwe n’umuvuduko mwinshi wa voltage bigenga ibice byinshi:

Igipimo Cyisaha Cyinshi & Urusaku rwinzibacyuho: Guhindura inshuro nyinshi murwego rwa gigahertz zitanga umurongo-mwinshi wa electromagnetic yumurima uhita uhunga unyuze mu cyuho gito cyangwa udukingirizo dufunze.

Ibimenyetso Byambukiranya Ibiganiro: EMI itagenzuwe irashobora gutera imitwe iriho mugihe cyihuta cyihuta cyihuta (urugero, PCIe 6.0 / NVLink), biganisha kubura paki no kubara amakosa.

Imipaka ya gakondo ya Bare Metallic Shielding Gaskets

Imyenda isanzwe ya aluminiyumu cyangwa nikel isize umuringa ukingira umuringa ukingira imikorere yangirika kubikorwa byubuzima bwagutse:

Inzitizi ya Oxidation ya Surface: Bare aluminiyumu isanzwe ikora urwego ruto, rukoresha amashanyarazi ya oxyde (Al₂O₃) iyo ihuye nikirere, ikongera imiyoboro ihuza imiyoboro kandi ikanangiza imikorere yo gukingira.

Ruswa ya Galvanic: Umuringa wuzuye cyangwa nikel ya gasike ihujwe na pansiyo ya aluminium ya chasisi itera itandukaniro rikomeye rya galvanike, byihuta kwangirika mubidukikije byamakuru.

Imiterere ya Geometrie & Slot Leakage Ibirimo

Umuvuduko mwinshi wa EMI (hejuru ya 1 GHz) uranga uburebure bwumurambararo uri munsi ya cm 30, bigatuma ushobora guhunga unyuze ahantu hafunganye hagati ya seriveri ya blade ya chasisi, ibipfukisho byimukanwa, hamwe nu mwanya wa kabili.

Ibikoresho bya tekinike Matrix: Imiyoboro ya Aluminium EMI

Imbonerahamwe ikurikira irerekana ibipimo ngenderwaho byingenzi bya tekinike ya aluminiyumu ikozwe neza yakozwe na AI supercomputer EMI / RFI ikingira:

Ibyiza byimikorere muri AI Supercomputer

Ibibazo

Q1: Nigute umurongo wa aluminiyumu utwikiriye ugereranije na kaseti gakondo ikingira umuringa?

Igisubizo: Inzira ya aluminiyumu itwikiriye itanga imbaraga zigereranywa zo gukingira ( > 80 dB ) hafi kimwe cya gatatu cy'uburemere bwa kaseti y'umuringa ( 2.7 g / cm ⊃3;  umurongo wa 8.9 g / cm ⊃3;), mugihe wirinze kwangirika kwa galvanike iyo ushyizwe kumurongo wa aluminium chassis.

IKIBAZO: Ese ibishishwa bitwikiriye cyangwa ibishishwa mugihe cyo kunama cyangwa gupfa?

. Igisubizo. Oya Bihanganira kugabanuka gukabije kwa dogere 180 no gupfa-kashe nta guhindagurika cyangwa gucamo mikoro.

Q4: Ese imirongo ya aluminiyumu itwikiriye irashobora gutangwa hamwe ningufu zogukoresha imbaraga (PSA)?

Igisubizo: Yego. Imirongo irashobora gukorwa hamwe na acrile ya acrile ya PSA yamuritse kuruhande rumwe, bigatuma igishishwa cyoroshye-inkoni mugihe cyo guteranya chassis mugihe gikomeza amashanyarazi binyuze mumashanyarazi.

Q5: Ni ubuhe buzima busanzwe bwo gutunga imirongo ikingira aluminiyumu?

Igisubizo: Iyo bibitswe ahantu hagenzurwa nikirere ( 20 ° C , 50%  RH) mugupakira uruganda rwa vacuum, imirongo ya aluminiyumu itwikiriwe neza ikomeza gukora amashanyarazi yose hamwe nubukanishi mumyaka irenga ibiri nta okiside yubutaka.

Umwanzuro

Kwishyira hamwe imiyoboro ya aluminiyumu ikora muri seriveri ya rack chassis hamwe nu mugozi wa kabili ituma abahanga mu byuma bya supercomputer bakemura ibibazo bikomeye bya EMI bigoye cyane mugihe bahindura sisitemu ya misa.

Kugirango uhindure ibikoresho byatoranijwe kuri AI supercomputer yawe:

Hitamo Strip Gauge ukoresheje Mechanical Flexibility: Kugaragaza 0,05mm - 0,10mm imirongo yoroheje, ifata ibyuma bifata kashe; koresha 0.15mm - 0,30mm imirongo ya clips zubatswe hamwe na gasketi yinama.

Manda Yagenzuwe Yerekana Shielding & Resistance Ratings: Menya neza ko imirongo igaragara igera kuburwanya ≤ 0.05  Ω / sq kandi igatanga ≥ 80 dB ikingira neza mugihe gikoreshwa.

Umufatanyabikorwa hamwe nimpuguke zemewe zo gutwikira ibicuruzwa: nabaproducer babimenyereye nka Changzhou Dingang Metal Material Co., Ltd. Korana
