Ha thekenoloji ea laser ea matla a phahameng e ntse e tsoela pele ka potlako, Laser Diode Bars (LDBs) e se e sebelisoa haholo ts'ebetsong ea indasteri, ho buuoa ka meriana, LiDAR, le lipatlisiso tsa saense ka lebaka la matla a tsona a phahameng a matla le tlhahiso e phahameng ea khanya. Leha ho le joalo, ka kopanyo e ntseng e eketseha le ts'ebetso ea morao-rao ea lisebelisoa tsa laser, mathata a tsamaiso ea mocheso a ntse a hlahella-ho ama ka ho toba botsitso ba ts'ebetso le bophelo bohle ba laser.
Har'a maano a fapaneng a taolo ea mocheso, Contact Conduction Cooling e hlahella e le e 'ngoe ea mekhoa ea bohlokoahali le e amohetsoeng ka bongata ho paketeng ea laser diode bar, ka lebaka la sebopeho sa eona se bonolo le conductivity e phahameng ea mocheso. Sehlooho sena se hlahloba melao-motheo, lintlha tsa bohlokoa tsa moralo, khetho ea thepa, le mekhoa ea nakong e tlang ea "tsela e khutsitseng" ea ho laola mocheso.
1. Melao-motheo ea Pholiso ea Khokahano ea Kopano
Joalo ka ha lebitso le fana ka maikutlo, pholiso ea conduction ea ho ikopanya e sebetsa ka ho theha khokahano e tobileng lipakeng tsa chip ea laser le sink ea mocheso, e nolofalletsang phetisetso e nepahetseng ea mocheso ka lisebelisoa tse phahameng tsa mocheso oa mocheso le ho qhalana ka potlako tikolohong ea kantle.
①The HjaPath:
Ka bareng e tloaelehileng ea laser diode, tsela ea mocheso e tjena:
Chip → Solder Layer → Tlase (mohlala, koporo kapa ceramic) → TEC (Thermoelectric Cooler) kapa Sink ea Mocheso → Tikoloho e Ambient
②Likaroloana:
Mokhoa ona oa ho pholisa o na le:
Phallo e matla ea mocheso le tsela e khuts'oane ea mocheso, ho fokotsa mocheso oa mateano ka katleho; Moqapi o tiileng, o loketseng ho paka ka miniaturized; Ho tsamaisa ka mokhoa o sa fetoheng, ho sa hlokeng hore ho se be le loops e pholileng e sebetsang.
2. Lintlha tsa Moqapi oa Bohlokoa bakeng sa Ts'ebetso ea Thermal
Ho etsa bonnete ba hore pholiso ea khokahanyo e sebetsang hantle, lintlha tse latelang li tlameha ho shejoa ka hloko nakong ea moralo oa sesebelisoa:
① Thermal Resistance ho Solder Interface
Thermal conductivity ea solder layer e phetha karolo ea bohlokoa ho hanyetsa mocheso ka kakaretso. Lisebelisoa tse phahameng tsa conductivity tse kang AuSn alloy kapa pure indium li lokela ho sebelisoa, 'me botenya ba solder le ho tšoana ho lokela ho laoloa ho fokotsa mekoallo ea mocheso.
② Khetho ea Lintho Tse Tlase
Lisebelisoa tse tloaelehileng tsa submount li kenyelletsa:
Koporo (Cu): Thermal conductivity e phahameng, e theko e tlaase;
Tungsten Copper (WCu)/Molybdenum Copper (MoCu): Papali e ntle ea CTE e nang le li-chips, e fanang ka bobeli matla le conductivity;
Aluminium Nitride (AlN): Motlakase o motle haholo, o loketseng lisebelisoa tse phahameng tsa motlakase.
③ Boleng ba ho Kopana le Bokaholimo
Ho ba mahoashe ka holim'a metsi, ho bata, le ho koloba ho ama ka kotloloho ho sebetsa hantle ha mocheso. Ho penta le ho roala khauta hangata ho sebelisoa ho ntlafatsa ts'ebetso ea ho kopana le mocheso.
④ Ho fokotsa Tsela ea Thermal
Moralo oa sebopeho o lokela ho ikemisetsa ho khutsufatsa tsela ea mocheso lipakeng tsa chip le sink ea mocheso. Qoba likarolo tse sa hlokahaleng tsa lisebelisoa tse mahareng ho ntlafatsa ts'ebetso ea ho felisa mocheso ka kakaretso.
3. Litaelo tsa Ntlafatso ea Bokamoso
Ka mokhoa o ntseng o tsoela pele oa miniaturization le matla a phahameng a matla, theknoloji ea pholiso ea likhokahano e ntse e tsoela pele ka litsela tse latelang:
① Li-TIM tse nang le mekhahlelo e mengata
Ho kopanya metallic thermal conduction le flexible buffering ho fokotsa khanyetso ea sebopeho le ho ntlafatsa ho tšoarella ha libaesekele tse futhumatsang.
② Sephutheloana sa Mocheso o Kopantsoeng
Ho theha li-submounts le licheso tsa mocheso e le mohaho o le mong o kopantsoeng ho fokotsa li-interfaces le ho eketsa bokhoni ba ho fetisa mocheso oa tsamaiso.
③ Ntlafatso ea Sebopeho sa Bionic
Ho sebelisa libaka tse nang le microstructured tse etsisang mekhoa ea tlhaho ea ho senya mocheso-joaloka "conduction e kang ea sefate" kapa "scale-like pattern" -ho matlafatsa ts'ebetso ea mocheso.
④ Taolo ea Thermal e Bohlale
Ho kenyelletsa li-sensor tsa mocheso le taolo e matla ea matla bakeng sa taolo e feto-fetohang ea mocheso, ho lelefatsa bophelo ba ts'ebetso ea sesebelisoa.
4. Qetello
Bakeng sa lisebelisoa tsa laser diode tse matla, taolo ea mocheso ha se phephetso ea tekheniki feela - ke motheo oa bohlokoa oa ho ts'epahala. Pholiso ea conduction ea ho kopana, e nang le litšobotsi tse sebetsang hantle, tse hōlileng tsebong, le tse theko e tlaase, e ntse e le e 'ngoe ea litharollo tse tloaelehileng bakeng sa ho qhala mocheso kajeno.
5. Mabapi le Rona
Ho Lumispot, re tlisa boiphihlelo bo tebileng ba ho paka ka laser diode, tlhahlobo ea taolo ea mocheso, le khetho ea thepa. Morero oa rona ke ho fana ka litharollo tsa laser tse sebetsang hantle haholo, tsa nako e telele tse tsamaellanang le litlhoko tsa kopo ea hau. Haeba u batla ho tseba haholoanyane, re u amohela ka mofuthu hore u ikopanye le sehlopha sa rona.
