Khetha izinto zokulahla ukushisa ze-PCB enezingqimba ezi-3

Ukukhetha izinto ezifanele zokulawula ukushisa nezinto zokukhipha ukushisa zama-PCB anezingqimba ezintathu kubalulekile ekwehliseni izinga lokushisa lezingxenye kanye nokuqinisekisa ukuzinza kwesistimu iyonke. Njengoba ubuchwepheshe buthuthuka, izinto zikagesi ziba zincane futhi zibe namandla kakhulu, okuholela ekwandeni kokukhiqizwa kokushisa. Lokhu kudinga amasu okuphatha okushisayo asebenzayo ukuvimbela ukushisa ngokweqile kanye nokwehluleka okungenzeka kwemishini.Kulokhu okuthunyelwe kwebhulogi, sizokuqondisa ukuthi ungakhetha kanjani izinto ezifanele zokulawula ukushisa kanye nokukhipha ukushisa kuma-PCB anezingqimba ezi-3.

1. Qonda ukubaluleka kokuphatha okushisayo

Ukuphathwa kwe-thermal kubalulekile ekuqinisekiseni ukusebenza okuthembekile kwemishini kagesi. Ukushisa okweqile kungaholela ekusebenzeni okuncishisiwe, ukusetshenziswa kwamandla okwenyuka, kanye nempilo yesevisi ibe mfushane. Ukupholisa okufanele kubalulekile ekugcineni izinga lokushisa ngaphakathi kwemikhawulo ephephile. Ukunganaki ukuphatha okushisayo kungaholela ekucindezelekeni kokushisa, ukuwohloka kwengxenye, noma ngisho nokwehluleka okuyinhlekelele.

2. Ukucatshangelwa Okubalulekile Kwezinto Zokulawula Ukushisa

Lapho ukhetha izinto zokuphatha ezishisayo zama-PCB anezingqimba ezi-3, lezi zinto ezilandelayo kufanele zibhekwe:

- Thermal conductivity:Ikhono lempahla ukuqhuba ukushisa ngempumelelo libalulekile. I-high conductivity eshisayo isusa ngokushesha ukushisa kusuka ezingxenyeni kuya endaweni ezungezile. Izinto ezifana nethusi ne-aluminium zisetshenziswa kakhulu ngenxa yezakhiwo zazo ezinhle kakhulu zokusebenzisa ukushisa.

- Ukufakwa kukagesi:Njengoba i-PCB enezingqimba ezi-3 iqukethe izendlalelo eziningi ezinezingxenye ezihlukahlukene ze-elekthronikhi, kubalulekile ukukhetha izinto ezihlinzeka ngokufaka ugesi okusebenzayo. Lokhu kuvimbela amasekhethi amafushane namanye amaphutha kagesi ohlelweni. Izinto zokuphatha ezishisayo ezinezakhiwo ezinhle zokuvikela ugesi ziyakhethwa, njenge-ceramics noma i-silicon-based compounds.

- Ukuhambisana:Izinto ezikhethiwe kufanele zihambisane nenqubo yokukhiqiza esetshenziselwa ukukhiqiza ama-PCB anezingqimba ezi-3. Kufanele zifanelekele i-lamination futhi zibe nokunamathela okuhle kwezinye izingqimba ze-PCB.

3. Izinto zokukhipha ukushisa ze-PCB enezingqimba ezi-3

Ukuthuthukisa ukusebenza okushisayo kwe-PCB enezingqimba ezi-3, kungasetshenziswa izinto ezahlukahlukene nobuchwepheshe:

- I-Thermal Interface Materials (TIM):I-TIM yehlisa ukumelana nokushisa ngokuthuthukisa ukudluliswa kokushisa phakathi kwezingxenye namasinki okushisa. Lezi zinto zigcwalisa izikhala zomoya we-microscopic phakathi kwendawo futhi ziza ngezindlela ezihlukahlukene, kufaka phakathi ama-thermal pads, ama-gel, ama-pastes kanye nezinto zokushintsha isigaba. Ukukhethwa kwe-TIM kuncike ezicini ezifana ne-thermal conductivity, ukungaguquguquki kanye nokusebenza kabusha.

- I-radiator:I-radiator inikeza indawo engaphezulu engaphezulu yokukhipha ukushisa. Ngokuvamile zenziwe nge-aluminium noma ngethusi futhi zinamathiselwe ezingxenyeni zamandla aphezulu zisebenzisa i-adhesive eshisayo noma izinsimbi zokubopha. Idizayini nokubekwa kukasinki wokushisa kufanele kuthuthukiswe ukuze kuqinisekiswe ukunqanyulwa kokushisa okusebenzayo.

- Isakhiwo Sebhodi Lesifunda:Isakhiwo esifanele se-PCB sidlala indima ebalulekile ekulahlekeni kokushisa. Ukuhlanganisa izingxenye zamandla aphezulu ndawonye nokuqinisekisa isikhala esanele phakathi kwazo kuvumela ukugeleza komoya okungcono futhi kunciphisa ukugxila kokushisa. Ukubeka izingxenye zokushisisa eduze kongqimba lwangaphandle lwe-PCB kukhuthaza ukuchithwa kokushisa okuphumelelayo ngokusebenzisa i-convection.

- Nge:I-Vias ingabekwa ngendlela ehlelekile ukuze iqhube ukushisa kusuka ezingqimbeni zangaphakathi ze-PCB kuya kwezendlalelo zangaphandle noma kusinki wokushisa. Lezi zindlela zisebenza njengezindlela ezishisayo futhi zithuthukisa ukuqeda ukushisa. Ukuma kahle kanye nokusatshalaliswa kwe-vias kubalulekile ekulawuleni izinga lokushisa elilungile.

4. Lungiselela ukuzinza kwesistimu ngokulawula okushisayo okusebenzayo

Ukuzinza kwesistimu ye-PCB enezingqimba ezi-3 kungathuthukiswa kakhulu ngokukhethwa ngokucophelela nokusebenzisa izinto ezifanele zokulawula ukushisa. Ukuphathwa kokushisa okwanele kunciphisa ingozi yokushisa ngokweqile futhi kuqinisekisa isikhathi eside sezingxenye ze-elekthronikhi, ngaleyo ndlela kukhulisa ukuthembeka kwesistimu.

Ngokufigqiwe

Ukukhetha ukuphathwa okushisayo okulungile nezinto zokukhipha ukushisa ze-PCB enezingqimba ezi-3 kubalulekile ekuvimbeleni ukushisa nokuqinisekisa ukuzinza kwesistimu. Ukuqonda ukubaluleka kokuphathwa kwe-thermal, ukucabangela izici ezifana ne-thermal conductivity kanye nokufakwa kukagesi, nokusebenzisa izinto ezifana nama-TIM, osinki bokushisa, ukuhlelwa kwebhodi okuthuthukisiwe, kanye nama-vias abekwe ngamasu kuyizinyathelo ezibalulekile ekufinyeleleni ukulawula okushisayo. Ngokubeka phambili ukuphatha okushisayo, ungavikela ukusebenza nokuphila isikhathi eside kwamadivayisi akho kagesi.
