Twandikire Gukonjesha Gukonjesha: "Gutuza Inzira" ya Power-Laser Diode Bar Porogaramu

Mugihe tekinoroji ya laser ifite ingufu nyinshi ikomeje gutera imbere byihuse, Laser Diode Bars (LDBs) imaze gukoreshwa cyane mugutunganya inganda, kubaga ubuvuzi, LiDAR, nubushakashatsi bwa siyansi bitewe nubucucike bwayo bwinshi kandi butanga umucyo mwinshi. Ariko, hamwe no kwiyongera kwishyira hamwe no gukoresha amashanyarazi ya laser, ibibazo byo gucunga ubushyuhe bigenda bigaragara cyane - bigira ingaruka kumikorere no mubuzima bwa laser.

Mu ngamba zinyuranye zo gucunga amashyuza, Contact Conduction Cooling igaragara nkimwe mubuhanga bwingenzi kandi bwakoreshejwe cyane mubipfunyika bwa laser diode, bitewe nuburyo bworoshye hamwe nubushyuhe bukabije bwumuriro. Iyi ngingo irasobanura amahame, ibitekerezo byingenzi byashizweho, guhitamo ibikoresho, hamwe nigihe kizaza cyiyi "nzira ituje" igenzura ubushyuhe.

1. Amahame yo Guhuza Gukonjesha

Nkuko izina ribigaragaza, guhuza ibikorwa byo gukonjesha bikora mugushiraho itaziguye hagati ya chip ya laser na sink yubushyuhe, bigafasha guhererekanya neza ubushyuhe binyuze mubikoresho bikoresha ubushyuhe bwinshi no gusohora vuba mubidukikije.

①The HkuryaPath:

Muburyo busanzwe bwa laser diode bar, inzira yubushyuhe nuburyo bukurikira:
Chip Lay Igice cya Solder → Umubare (urugero, umuringa cyangwa ceramic) → TEC (Cooler ya Thermoelectric Cooler) cyangwa Sink Sink → Ibidukikije

②Ibiranga:

Ubu buryo bwo gukonjesha buranga:

Ubushyuhe bukabije hamwe n'inzira ngufi yubushyuhe, bigabanya neza ubushyuhe bwihuriro; Igishushanyo mbonera, kibereye gupakira miniaturizasi; Gutwara pasiporo, bisaba ko bitagoranye gukonjesha gukonje.

2. Ibyingenzi Byingenzi Ibitekerezo Byibikorwa byubushyuhe

Kugirango umenye neza uburyo bwo guhuza imiyoboro ikonje, ingingo zikurikira zigomba gukemurwa neza mugihe cyo gushushanya ibikoresho:

Res Kurwanya Ubushyuhe Kumurongo wa Solder

Ubushyuhe bwumuriro bwurwego rwabigurisha bugira uruhare runini mukurwanya ubushuhe muri rusange. Ibyuma bitwara ibintu byinshi nka AuSn alloy cyangwa indium yera bigomba gukoreshwa, kandi umubyigano wububiko hamwe nuburinganire bigomba kugenzurwa kugirango hagabanuke inzitizi zubushyuhe.

Gutoranya Ibikoresho

Ibikoresho rusange byoherejwe birimo:

Umuringa (Cu): Ubushyuhe bukabije bwumuriro, buhendutse;

Umuringa wa Tungsten (WCu) / Umuringa wa Molybdenum (MoCu): Umukino mwiza wa CTE hamwe na chip, utanga imbaraga nubushobozi;

Aluminium Nitride (AlN): Gukoresha amashanyarazi meza cyane, bikwiranye na voltage nyinshi.

③ Ubuso Bwiza Bwiza

Ubuso bwubuso, uburinganire, hamwe nubushuhe bigira ingaruka muburyo bwo kohereza ubushyuhe. Amashanyarazi hamwe na zahabu akenshi bikoreshwa mugutezimbere imikorere yumuriro.

Kugabanya Inzira yubushyuhe

Igishushanyo mbonera kigomba kuba kigamije kugabanya inzira yubushyuhe hagati ya chip na sink. Irinde ibikoresho bidakenewe hagati kugirango bidatezimbere ubushyuhe muri rusange.

3. Icyerekezo cy'iterambere ry'ejo hazaza

Hamwe nimyumvire ikomeje kugana miniaturizasi hamwe nubucucike bukabije, tekinoroji yo gukonjesha itumanaho iragenda ihinduka mubyerekezo bikurikira:

① Ibice byinshi bigize TIMs

Gukomatanya imiyoboro yubushyuhe bwumuriro hamwe na bffer yoroheje kugirango igabanye guhangana ninteruro kandi itezimbere igihe cyamagare yumuriro.

Gapakira Ubushyuhe Bwuzuye

Gushushanya ibicuruzwa hamwe nubushyuhe buringaniye nkuburyo bumwe bwahujwe kugirango ugabanye imikoranire no kongera sisitemu yohereza ubushyuhe neza.

Opt Optimisiyonike ya Bionic

Gukoresha microstructures hejuru yigana uburyo bwo gukwirakwiza ubushyuhe bwa kamere-nka "imiyoboro imeze nkibiti" cyangwa "ibishushanyo bisa" - kugirango byongere imikorere yubushyuhe.

Control Igenzura ryubushyuhe bwubwenge

Kwinjizamo ibyuma byubushyuhe hamwe nimbaraga zigenzura imbaraga zo gucunga neza imiterere yubushyuhe, kwagura ubuzima bwimikorere yibikoresho.

4. Umwanzuro

Kubububasha bukomeye bwa laser diode, imicungire yubushyuhe ntabwo ari ikibazo cya tekiniki gusa - ni umusingi wingenzi wo kwizerwa. Guhuza imiyoboro ikonje, hamwe nibikorwa byayo byiza, bikuze, kandi bikoresha ikiguzi, biracyari kimwe mubisubizo nyamukuru byo gukwirakwiza ubushyuhe muri iki gihe.

5. Ibyerekeye Twebwe

Kuri Lumispot, tuzanye ubuhanga bwimbitse mugupakira laser diode, gusuzuma imicungire yumuriro, no guhitamo ibikoresho. Inshingano yacu ni ugutanga imikorere-ndende, igihe kirekire-laser ibisubizo bikwiranye nibyo ukeneye. Niba wifuza kumenya byinshi, turakwishimiye cyane kugirango ubonane nikipe yacu.
