Gukonjesha Guhuza Ibikoresho: "Inzira Ituje" yo Gukoresha Diode Bar ya Laser Ifite Ingufu Nyinshi

Uko ikoranabuhanga rya laser rikoresha imbaraga nyinshi rikomeza gutera imbere vuba, Laser Diode Bars (LDBs) zakoreshejwe cyane mu gutunganya inganda, kubaga, LiDAR, no mu bushakashatsi bwa siyansi bitewe n'ubucucike bwazo bw'imbaraga nyinshi n'umusaruro mwinshi w'urumuri. Ariko, hamwe no kwiyongera k'uburyo bwa laser chips zikoreshwa, imbogamizi zo gucunga ubushyuhe zirushaho kugaragara - zigira ingaruka ku buryo butaziguye ku mikorere no ku buzima bwa laser.

Mu ngamba zitandukanye zo gucunga ubushyuhe, gukoresha uburyo bwo gukonjesha hakoreshejwe uburyo bwa "Contact Conduction Cooling" bigaragarira cyane mu gupakira ibikoresho bya laser diode bar, bitewe n'imiterere yabyo yoroshye kandi bitanga ubushyuhe bwinshi. Iyi nkuru irasuzuma amahame ngenderwaho, imiterere y'ingenzi, guhitamo ibikoresho, n'ibizagenderwaho mu gihe kizaza muri iyi "nzira ituje" yo kugenzura ubushyuhe.

1. Amahame yo Gukonjesha Guhuza Ibikoresho

Nk’uko izina ribigaragaza, gukonjesha uburyo bwo kohereza ibintu mu buryo bw’ikoranabuhanga bikora binyuze mu gushyiraho uburyo butaziguye hagati ya chip ya laser n’icyuma gishyushya, bigatuma ubushyuhe bwiyongera neza binyuze mu bikoresho bishyushya cyane kandi bigakwirakwira vuba mu kirere cyo hanze.

①The HKuryaPath:

Mu gice gisanzwe cya laser diode, inzira y'ubushyuhe ni iyi ikurikira:
Chip → Urupapuro rwo gusoda → Submount (urugero, umuringa cyangwa ceramic) → TEC (Thermoelectric Cooler) cyangwa Ubushyuhe bwo gukaraba → Ahantu hakikije

②Ibiranga:

Ubu buryo bwo gukonjesha bufite ibi bikurikira:

Umuvuduko w'ubushyuhe bwinshi n'inzira ngufi y'ubushyuhe, bigabanya ubushyuhe bw'aho bihurira; Igishushanyo gito, gikwiriye gupakirwa mu buryo buto; Gutanga umuvuduko udakora, udasaba imiyoboro igoye yo gukonjesha.

2. Ibitekerezo by'ingenzi ku gishushanyo mbonera cy'imikorere y'ubushyuhe

Kugira ngo igikoresho gikonje neza, ingingo zikurikira zigomba kwitabwaho neza mu gihe cyo gushushanya igikoresho:

① Ubudahangarwa bw'ubushyuhe kuri Solder Interface

Uburyo ubushyuhe butwara urwego rw'icyuma gishongesha bigira uruhare runini mu kurwanya ubushyuhe muri rusange. Hagomba gukoreshwa ibyuma bifite ubushyuhe bwinshi nka AuSn alloy cyangwa pure indium, kandi ubugari n'ubugari bw'urwego rw'icyuma gishongesha bigira uruhare runini mu kugabanya ubushyuhe.

② Guhitamo ibikoresho byo munsi y'ubutaka

Ibikoresho bisanzwe byo gushyira munsi y'ubutaka birimo:

Umuringa (Cu): Ubushobozi bwo gutwara ubushyuhe bwinshi, buhendutse;

Umuringa wa Tungsten (WCu)/Umuringa wa Molybdenum (MoCu): CTE ihuye neza n'udupira, itanga imbaraga n'ubushobozi bwo gutwara ibintu;

Aluminium Nitride (AlN): Ingufu nziza cyane zo gukingira amashanyarazi, zikwiriye gukoreshwa mu gukoresha ingufu nyinshi.

③ Ubwiza bw'aho ibintu bihurira

Ubushyuhe, ubugari, no kutagira amazi bigira ingaruka ku buryo butaziguye ku buryo bwo kohereza ubushyuhe. Gusukura no gusiga zahabu akenshi bikoreshwa mu kunoza imikorere y'ubushyuhe.

④ Kugabanya Inzira y'Ubushyuhe

Imiterere y'inyubako igomba kugamije kugabanya inzira y'ubushyuhe hagati y'icyuma n'icyuma gishyushya. Irinde gushyira ibikoresho biri hagati bitari ngombwa kugira ngo wongere imikorere myiza yo gukwirakwiza ubushyuhe muri rusange.

3. Ibyerekeye iterambere ry'ejo hazaza

Bitewe n'icyerekezo gikomeje cyo gukora miniaturization no kwiyongera k'ubucucike bw'ingufu, ikoranabuhanga ryo gukonjesha mu buryo bwo gutumanaho rigenda ritera imbere mu byerekezo bikurikira:

① TIM z'ibice byinshi

Guhuza uburyo bwo gutwara ubushyuhe bw'icyuma hamwe n'uburyo bworoshye bwo gufunga kugira ngo bigabanye ubushobozi bwo guhangana n'ubushyuhe no kunoza kuramba kw'ubushyuhe.

② Ipaki y'ibikoresho byo gupakiramo ubushyuhe

Gushushanya imiyoboro y'amashanyarazi n'ibigega by'ubushyuhe nk'inyubako imwe ihuriweho kugira ngo bigabanye uburyo bwo guhuza ibintu no kongera imikorere myiza yo kohereza ubushyuhe ku rwego rwa sisitemu.

③ Gutunganya Imiterere ya Bionic

Gukoresha ubuso bufite imiterere mito isa n'uburyo busanzwe bwo gukwirakwiza ubushyuhe—nk' “uburyo bumeze nk'igiti” cyangwa “imiterere isa n'iy'ubunini”—kugira ngo hongerwe imikorere y'ubushyuhe.

④ Uburyo bwo kugenzura ubushyuhe bw'ubwenge

Gushyiramo ibikoresho bipima ubushyuhe n'igenzura ry'ingufu zihindagurika mu gucunga ubushyuhe, bikongera igihe cyo gukora cy'igikoresho.

4. Umwanzuro

Ku byerekeye imiyoboro ya laser diode ifite imbaraga nyinshi, gucunga ubushyuhe si ikibazo cya tekiniki gusa—ni ishingiro ry'ingenzi ryo kwizera. Gukonjesha icyuma gikonjesha, gifite imiterere myiza, ikuze kandi ihendutse, biracyari kimwe mu bisubizo by'ingenzi byo gukwirakwiza ubushyuhe muri iki gihe.

5. Ibyerekeye Twe

Muri Lumispot, tuzanye ubumenyi bwimbitse mu gupakira diode ya laser, isuzuma ry’imicungire y’ubushyuhe, no guhitamo ibikoresho. Intego yacu ni ugutanga ibisubizo bya laser bikora neza kandi birambye bijyanye n’ibyo ukeneye. Niba wifuza kumenya byinshi, turakwakira neza kugira ngo utwandikire n’ikipe yacu.
