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 cyo guhinduranya ibimenyetso bitanga amashanyarazi akomeye (EMI) hamwe na radiyo-interineti (RFI). Urusaku rwinshi rwo guhinduranya urusaku ruvuye muri kilowatt nyinshi zo gukwirakwiza amashanyarazi (PDUs) hamwe na transiteri yihuta ya optique irashobora guhungabanya byoroshye imiyoboro yerekana ibimenyetso byegeranye mugihe uruzitiro rufunze, insinga za kabili, hamwe nintera ya rack bidafunze hamwe nibikoresho bikingira neza.

Gukoresha imiyoboro ya aluminiyumu itwikiriye (0,05 mm - 0,3 mm) yerekana karuboni yuzuye yuzuye ya karubone cyangwa metallic-doped hejuru yubutaka itanga uburyo bwiza bwo gukingira (> 80 dB hejuru ya 100 MHz - 10 GHz), kurwanya amashanyarazi adasanzwe cyane, hamwe nuburyo bworoshye bwimiterere yibisekuru bizaza bya AI supercomputer.

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 paneli ya aluminium ya chasisi itera itandukaniro rikomeye rya galvanike, byihuta kwangirika mubidukikije byamakuru.

Imiterere ya Geometrie & Slot Leakage Ibirimo

Umuyoboro 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 chassis, ibipfukisho byimukanwa, hamwe nu mwanya wo kugera kumurongo.

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.

.Igisubizo ​​​

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

Igisubizo: Yego. Imirongo irashobora gukorwa hamwe na acrile ya acrylic ya PSA yamurikiwe 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 mubidukikije bigenzurwa nikirere ( 20 ° C , 50%  RH) mubipfunyika mu ruganda, imirongo ya aluminiyumu ikozwe neza ikomeza gukora amashanyarazi yose hamwe nubukanishi mumyaka irenga ibiri nta okiside yubutaka.

Umwanzuro

Kwishyira hamwe imiyoboro ya aluminiyumu itwikiriye muri seriveri ya rack chassis hamwe nu mugozi wa kabili ituma abahanga mu byuma bya mudasobwa ya supercomputer bakemura ibibazo bigoye cyane bya EMI mugihe cyo guhindura 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 yagenwe 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
