Cooling Gudanar da Tuntuɓi: “Hanyar Kwanciyar hankali” don Aikace-aikacen Bar Laser Diode Bar

Kamar yadda fasahar Laser mai ƙarfi ke ci gaba da haɓaka cikin sauri, Laser Diode Bars (LDBs) sun zama masu amfani da yawa a cikin sarrafa masana'antu, aikin tiyata, LiDAR, da binciken kimiyya saboda ƙarfin ƙarfinsu da haɓakar haske. Koyaya, tare da haɓaka haɓakawa da aiki na yanzu na kwakwalwan Laser, ƙalubalen gudanarwa na thermal suna zama mafi shahara - kai tsaye yana tasiri kwanciyar hankali da rayuwar laser.

Daga cikin dabarun sarrafa zafi daban-daban, Kula da Tuntuɓar Sadarwa ya fito waje a matsayin ɗayan mafi mahimmanci kuma dabarun da aka yarda da su a cikin marufi na diode Laser, godiya ga tsarinsa mai sauƙi da haɓakar yanayin zafi. Wannan labarin yana bincika ƙa'idodi, mahimman la'akari da ƙira, zaɓin kayan aiki, da kuma yanayin gaba na wannan "hanyar kwantar da hankali" zuwa kula da thermal.

1. Ka'idodin Sabis na Sadarwar Sadarwa

Kamar yadda sunan ya nuna, tuntuɓar gudanarwar kwantar da hankali yana aiki ta hanyar kafa hulɗar kai tsaye tsakanin guntu Laser da ƙwanƙwasa zafi, yana ba da damar ingantacciyar hanyar canja wurin zafi ta hanyar manyan kayan haɓakar thermal da saurin watsawa zuwa yanayin waje.

①The HciPath:

A cikin mashigin diode na laser na yau da kullun, hanyar zafi shine kamar haka:
Chip → Solder Layer → Submount (misali, jan karfe ko yumbu) → TEC (Thermoelectric Cooler) ko Heat nutse → muhallin yanayi

②Siffofin:

Wannan hanyar sanyaya tana da fasali:

Matsakaicin zafin zafi da gajeriyar hanyar thermal, yadda ya kamata rage junction zafin jiki; Ƙararren ƙira, wanda ya dace da marufi kaɗan; Gudanar da wucewa, ba buƙatar hadaddun madaukai masu sanyaya aiki ba.

2. Mahimman Bayanan Ƙira don Ƙarfafa Ƙwararru

Don tabbatar da ingantaccen sanyaya hanyar sadarwa, dole ne a magance abubuwan da ke gaba a hankali yayin ƙirar na'urar:

① Juriya na thermal at the Solder Interface

Ƙunƙarar zafin zafi na Layer solder yana taka muhimmiyar rawa a cikin juriyar zafin zafi gabaɗaya. Ya kamata a yi amfani da ƙarfe masu ƙarfi irin su AuSn alloy ko indium mai tsafta, kuma a sarrafa kauri da kauri na solder don rage shingen zafi.

② Zaɓin Ƙarƙashin Ƙarfafawa

Kayayyakin ƙasa na gama gari sun haɗa da:

Copper (Cu): High thermal conductivity, farashi-tasiri;

Tungsten Copper (WCu) / Molybdenum Copper (MoCu): Mafi kyawun wasan CTE tare da kwakwalwan kwamfuta, yana ba da ƙarfi da haɓakawa;

Aluminum Nitride (AlN): Kyakkyawan rufin lantarki, dacewa da aikace-aikacen ƙarfin lantarki.

③ Ingancin Tuntuɓar Sama

Ƙunƙarar saman ƙasa, laushi, da ɗorewa kai tsaye suna shafar ingancin canjin zafi. Ana amfani da goge goge da platin zinari sau da yawa don inganta aikin sadarwar zafi.

④ Rage Tafarkin Zazzabi

Tsarin tsarin ya kamata yayi nufin rage hanyar zafi tsakanin guntu da matattarar zafi. Guji yadudduka na kayan tsaka-tsaki maras buƙata don haɓaka haɓakar zafi gabaɗaya.

3. Hanyoyi na Ci gaba na gaba

Tare da ci gaba da ci gaba zuwa ƙarami da ƙarfin ƙarfin ƙarfi, fasahar sanyaya lamba tana haɓaka ta hanyoyi masu zuwa:

① Multi-Layer Composite TIMs

Haɗa sarrafa wutar lantarki ta ƙarfe tare da sassauƙan buffer don rage juriya na mu'amala da haɓaka ƙarfin hawan keken zafi.

② Haɗaɗɗen Marufi Mai Ruwa

Ƙirƙirar ƙaƙƙarfan ƙaƙƙarfan ƙaƙƙarfan zafi da nutsewar zafi azaman tsarin haɗin kai guda ɗaya don rage mu'amalar tuntuɓar juna da haɓaka ingantaccen canjin yanayin zafi na tsarin.

③ Inganta Tsarin Bionic

Aiwatar da filaye masu ƙayatarwa waɗanda ke kwaikwayi hanyoyin watsar da zafi na yanayi-kamar “kamar bishiya” ko “tsari-kamar sikeli”—don haɓaka aikin zafi.

④ Ƙwararren Ƙwararrun Ƙwararrun Ƙwararru

Haɗa na'urori masu auna zafin jiki da ƙarfin ikon sarrafa wutar lantarki don daidaita yanayin zafi, tsawaita rayuwar aikin na'urar.

4. Kammalawa

Don sanduna diode mai ƙarfi na Laser, sarrafa zafin jiki ba ƙalubalen fasaha ba ne kawai - tushe ne mai mahimmanci don dogaro. Tuntuɓi mai sanyaya sanyaya, tare da ingantaccen, balagagge, da halaye masu tsada, ya kasance ɗaya daga cikin manyan hanyoyin magance zafi a yau.

5. Game da Mu

A Lumispot, muna kawo gwaninta mai zurfi a cikin marufi na laser diode, kimantawar sarrafa zafi, da zaɓin kayan. Manufarmu ita ce samar da babban aiki, mafita na Laser na tsawon rai wanda aka keɓance da bukatun aikace-aikacen ku. Idan kuna son ƙarin koyo, muna maraba da ku sosai don tuntuɓar ƙungiyarmu.
