Kuziziritsa kwa Kulumikizana ndi Kukhudza: "Njira Yofatsa" ya Mapulogalamu a Laser Diode Bar Amphamvu Kwambiri

Pamene ukadaulo wa laser wamphamvu kwambiri ukupitilira patsogolo mofulumira, Laser Diode Bars (LDBs) yakhala ikugwiritsidwa ntchito kwambiri mu mafakitale, opaleshoni yachipatala, LiDAR, ndi kafukufuku wasayansi chifukwa cha kuchuluka kwa mphamvu zawo komanso kuwala kwawo kwakukulu. Komabe, chifukwa cha kuphatikizana ndi mphamvu yogwiritsira ntchito ma laser chips, zovuta zoyendetsera kutentha zikuonekera kwambiri—zomwe zikukhudza mwachindunji kukhazikika kwa magwiridwe antchito ndi moyo wa laser.

Pakati pa njira zosiyanasiyana zoyendetsera kutentha, Contact Conducting Cooling ndi imodzi mwa njira zofunika kwambiri komanso zogwiritsidwa ntchito kwambiri pokonza ma laser diode bar, chifukwa cha kapangidwe kake kosavuta komanso kutentha kwambiri. Nkhaniyi ikufotokoza mfundo, mfundo zazikulu zoganizira pa kapangidwe kake, kusankha zinthu, ndi zomwe zikuchitika mtsogolo mwa "njira yodekha" iyi yowongolera kutentha.

1. Mfundo Zokhudza Kuziziritsa kwa Kukhudza

Monga momwe dzinalo likusonyezera, kuziziritsa kwa contact contact contact contact contact contact contact contact contact contact contact contact contact contact contact contact direct frame pakati pa laser chip ndi heat sink, zomwe zimathandiza kuti kutentha kusamutsidwe bwino kudzera mu zipangizo zotentha kwambiri komanso kufalikira mwachangu ku malo akunja.

①The HidyaniPath:

Mu bala la laser diode, njira yotenthetsera ndi iyi:
Chip → Solder Layer → Submount (monga, mkuwa kapena ceramic) → TEC (Thermoelectric Cooler) kapena Heat Sink → Malo Ozungulira

②Mawonekedwe:

Njira yozizira iyi ili ndi izi:

Kutentha kotentha kwambiri komanso njira yochepa yotenthetsera, zomwe zimachepetsa kutentha kwa malo olumikizirana; Kapangidwe kakang'ono, koyenera kupakidwa pang'ono; Kutulutsa mpweya pang'onopang'ono, kosafunikira kuzungulira kozizira kogwira ntchito.

2. Zofunika Kwambiri Zoganizira Pakapangidwe ka Matenthedwe

Kuti chipangizocho chizizire bwino, zinthu zotsatirazi ziyenera kuganiziridwa mosamala popanga chipangizocho:

① Kukana kwa Kutentha pa Chiyankhulo cha Solder

Kuthamanga kwa kutentha kwa gawo la solder kumachita gawo lofunikira kwambiri pakukana kutentha konse. Zitsulo zothamanga kwambiri monga AuSn alloy kapena pure indium ziyenera kugwiritsidwa ntchito, ndipo makulidwe ndi kufanana kwa gawo la solder kuyenera kulamulidwa kuti kuchepetse zotchinga kutentha.

② Kusankha Zinthu Zosanjikiza

Zipangizo zodziwika bwino zosungira pansi zimaphatikizapo:

Mkuwa (Cu): Kutentha kwambiri, kotsika mtengo;

Mkuwa wa Tungsten (WCu)/Mkuwa wa Molybdenum (MoCu): CTE imagwirizana bwino ndi ma chips, zomwe zimapangitsa kuti ikhale yolimba komanso yoyendetsa bwino magetsi;

Aluminiyamu Nitride (AlN): Chotetezera magetsi chabwino kwambiri, choyenera kugwiritsidwa ntchito ndi magetsi amphamvu.

③ Ubwino Wokhudzana ndi Malo

Kukhwima kwa pamwamba, kusalala, ndi kunyowa zimakhudza mwachindunji momwe kutentha kumayendera bwino. Kupukuta ndi golide nthawi zambiri zimagwiritsidwa ntchito pokonza momwe kutentha kumakhudzira.

④ Kuchepetsa Njira Yotenthetsera

Kapangidwe kake kayenera kukhala kofupikitsa njira yotenthetsera pakati pa chip ndi chotenthetsera. Pewani zigawo zosafunikira zapakati kuti muwongolere bwino kutentha konse.

3. Malangizo a Chitukuko cha M'tsogolo

Popeza kuti zinthu zikuchulukirachulukira pakupanga zinthu zazing'ono komanso mphamvu zambiri, ukadaulo woziziritsira wa contact ...

① Ma TIM Ophatikizana Ambiri

Kuphatikiza kutentha kwachitsulo ndi buffering yosinthasintha kuti muchepetse kukana kwa mawonekedwe ndikuwongolera kulimba kwa kutentha.

② Phukusi Lophatikizana la Sinki Yotenthetsera

Kupanga ma submount ndi ma heat sink ngati kapangidwe kamodzi kogwirizana kuti muchepetse kulumikizana kwa ma contact interfaces ndikuwonjezera magwiridwe antchito otumizira kutentha pamlingo wa dongosolo.

③ Kukonza Kapangidwe ka Bionic

Kugwiritsa ntchito malo okhala ndi mawonekedwe ang'onoang'ono omwe amatsanzira njira zachilengedwe zochotsera kutentha—monga “kutulutsa kofanana ndi mtengo” kapena “mawonekedwe ofanana ndi sikelo”—kuti kuwonjezere magwiridwe antchito a kutentha.

④ Kulamulira kwa Matenthedwe Anzeru

Kuphatikiza masensa otenthetsera ndi mphamvu yowongolera mphamvu kuti azitha kusintha kutentha, kukulitsa nthawi yogwirira ntchito ya chipangizocho.

4. Mapeto

Pa mipiringidzo ya laser diode yamphamvu kwambiri, kuyang'anira kutentha si vuto laukadaulo lokha—ndi maziko ofunikira kwambiri odalirika. Kuziziritsa kwa contact conduction, komwe kumakhala kogwira mtima, kokhwima, komanso kotsika mtengo, kumakhalabe njira imodzi yodziwika bwino yothanirana ndi kutentha masiku ano.

5. Zambiri Zokhudza Ife

Ku Lumispot, timabweretsa ukatswiri wozama pakupanga ma laser diode, kuwunika kasamalidwe ka kutentha, komanso kusankha zinthu. Cholinga chathu ndikupereka mayankho a laser ogwira ntchito bwino komanso a nthawi yayitali ogwirizana ndi zosowa zanu. Ngati mukufuna kudziwa zambiri, tikukulandirani ndi manja awiri kuti mulumikizane ndi gulu lathu.
