Li-Heat Sinks ke Eng ho Li-PCB?

Sekoaelo sa mocheso ke karolo ea ho pholisa e sa sebetseng e sebelisoang ho li-PCB ho theola mocheso hole le likarolo tsa elektroniki tse hlahisang mocheso. E phetha karolo ea bohlokoa ho thibela mocheso o feteletseng, ho netefatsa hore likaroloana li sebetsa ka har'a mocheso o sireletsehileng.

Lisinki tsa mocheso mererong ea PCB li lokela ho khethoa ho nahanoa ka ho bokellana ha boto, botenya ba koporo, le tahlehelo ea likarolo; meralo ea matla a teteaneng e ka rua molemo kahong ea PCB ea tšepe kapa tlhahiso ea PCB ea aluminium.

Mokhoa oa ho futhumatsa mocheso ho li-PCB

Mosebetsi o ka sehloohong oa sekoahelo sa mocheso ke ho monya le ho qhala mocheso ho tloha likarolong tse phahameng tsa mocheso ho ea libakeng tse pholileng, hangata moea o potolohileng. Sena se finyelloa ka mokhoa oa convection. Licheso tsa mocheso hangata li entsoe ka litšepe tse kang aluminium kapa koporo ka lebaka la ts'ebetso ea tsona e ntle ea mocheso. Moqapi oa mocheso oa mocheso o kenyelletsa letoto la li-fins kapa li-pins, tse eketsang sebaka se ka holimo ho kopana le moea, ka hona ho matlafatsa ts'ebetso ea ho senya mocheso.

Licheso tsa Mocheso ka har'a li-PCB li bohlokoa ho Moralo oa PCB

Lichelete tsa mocheso li bohlokoa bakeng sa tsamaiso ea mocheso, haholo-holo lipotolohong tsa motlakase tse matla haholo le tse phahameng haholo. Phallo e sebetsang ea mocheso e netefatsa hore likarolo tse kang li-CPU, li-GPU, li-transistors tsa motlakase, le mabone a LED li sebetsa ka har'a mocheso oa tsona o sireletsehileng, ho thibela ho baleha ha mocheso le ho netefatsa ts'epo le ts'ebetso. Taolo e sa lekaneng ea mocheso e ka lebisa ho hloleheng ha likarolo, ho fokotsa nako ea bophelo, le maemo a ka bang kotsi.

• Khetho ea Lintho: Khetho ea thepa e ama ts'ebetso ea mocheso oa sink ea mocheso le katleho e akaretsang. Aluminium e atisa ho sebelisoa bakeng sa ho leka-lekana pakeng tsa theko, boima le thepa ea mocheso, ha koporo e fana ka conductivity e phahameng ea mocheso empa ka theko e phahameng le boima ba 'mele.
• Boholo le Sebōpeho: Boholo le sebōpeho sa mocheso oa mocheso o itšetlehile ka boholo ba mocheso o lokelang ho qhaloa le sebaka se fumanehang ho PCB. Lithako tse kholo tsa mocheso tse nang le mapheo a mangata li ka qhala mocheso o mongata empa li hloka sebaka se eketsehileng.
• Fin Design: Moralo oa mapheoana a ama sekhahla sa phetiso ea mocheso. Mapheo a malelele le a nang le sebaka se seholoanyane a ka tlosa mocheso o mongata, empa hape a hloka moea o lekaneng hore o sebetse.
• Mokhoa oa ho Beha Mocheso: Ho hokelloa ha sekoaelo sa mocheso ho karolo ho bohlokoa bakeng sa phetisetso e nepahetseng ea mocheso. Likhetho li kenyelletsa litheipi tsa sekhomaretsi, li-epoxy, li-screw kapa likotoana. Tšebeliso ea lisebelisoa tsa mocheso oa mocheso (TIMs) joalo ka grease ea mocheso kapa li-pads pakeng tsa motsoako le mocheso oa mocheso ke oa bohlokoa ho fokotsa ho hanyetsa mocheso.
• Ntlafatso ea Phallo ea Moea: Hore sinki ea mocheso e sebetse hantle, ho tlameha ho be le moea o lekaneng ho e potoloha ho tlosa mocheso o qhalaneng. Maemong a mang, mekhoa ea ho pholisa e sebetsang joalo ka li-fan e ka sebelisoa ho matlafatsa phallo ea moea.
• Thermal Performance Simulation: Ho sebelisa software ea ketsiso ea mocheso nakong ea moralo ho thusa ho bolela esale pele ts'ebetso ea sink ea mocheso le ho ntlafatsa moralo oa eona bakeng sa ts'ebeliso e itseng.

Ha projeke e tloha ho dipatlisiso ho ya ho RFQ, hlahloba kopanyo ya PCB ya transformer le moralo wa tshireletso ya motlakase o feteletseng e le hore ditlhoko tsa thepa, tshebetso le tlhahlobo di dule di tsamaellana.

Lisebelisoa tse Tloaelehileng tsa Licheso tsa Mocheso ho PCB

Licheso tsa mocheso li sebelisoa haholo lits'ebetsong tse fapaneng tsa elektroniki, ho kenyelletsa:

• Lik'homphieutha le Li-server: Bakeng sa ho pholisa li-CPU, li-GPU, le li-chipsets.
• Matla a Elektronike: Lisebelisoa tse kang liamplifiers tsa motlakase, li-converter le li-voltage regulator.
• Leseli la LED: Ho laola mocheso o hlahisoang ke li-LED tse nang le matla a phahameng.
• Electronics ea Likoloi: Lits'ebetsong tse joalo ka likarolo tsa taolo ea makoloi le litsamaiso tsa mabone a pele.

  Licheso tsa mocheso li bapala karolo ea bohlokoa taolong ea mocheso oa PCB. Ka ho utloisisa ts'ebetso ea bona, bohlokoa le menahano ea moralo, baenjiniere le baqapi ba ka theha lisebelisoa tsa elektroniki tse tšepahalang le tse sebetsang hantle. Ha theknoloji e ntse e tsoela pele, tlhokahalo ea litharollo tse sebetsang tsa taolo ea mocheso joalo ka licheso tsa mocheso e ntse e ba bohlokoa haholo indastering ea lisebelisoa tsa elektroniki.
