Igishushanyo cyaubushyuhenikintu cyingenzi kigena ubushyuhe bwo gukwirakwiza ubushyuhe bwa sink.Urebye uburyo bwo gukwirakwiza ubushyuhe, muri rusange bigabanijwemo intambwe eshatu:kwinjiza ubushyuhe, gutwara ubushyuhe no gukwirakwiza ubushyuhe.Kubwibyo, igishushanyo mbonera cy’ubushyuhe kigomba gutangirana nizi ntambwe eshatu kugirango tunoze imikorere yo kwinjiza ubushyuhe, gutwara ubushyuhe no gukwirakwiza ubushyuhe, kugirango tubone ingaruka nziza zo gukwirakwiza ubushyuhe muri rusange.Ibikoresho byo gukora ubushyuhe ni ikintu cyingenzi kigira ingaruka kumikorere, kigomba kwitabwaho muguhitamo, ariko ibikoresho byumuriro ntibishobora kumenya imikorere yabyo muri rusange.Ikintu nyacyo cyo kunoza imikorere yubushyuhe ni igishushanyo mbonera.
Igishushanyo mbonera cyo gushushanya ubushyuhe
Mugihe cyo gushushanya ubushyuhe bwibicuruzwa bya elegitoronike, nuburyo busanzwe bwo gukoresha ubushyuhe bwumuriro mugushushanya.Igisobanuro cyo kurwanya ubushyuhe ni: R = △ T / P.
△ T bisobanura itandukaniro ryubushyuhe, mugihe P yerekana imbaraga zo gukoresha ubushyuhe bwa chip.Kurwanya ubushyuhe byerekana ingorane zo guhererekanya ubushyuhe bwigikoresho.Ninini agaciro, ningaruka mbi yo gukwirakwiza ubushyuhe bwigikoresho, kandi nagaciro gake, niko kugabanuka ubushyuhe.
Amabwiriza Rusange Amabwiriza yubushyuhe
1. Igishushanyo mbonera cy'ubushyuhe
Ingano yubushyuhe isobanura ingano ikoreshwa nubushyuhe.Muri rusange, uko imbaraga zo gushyushya ibicuruzwa bya elegitoronike nini, nini nini yubushyuhe bukenewe.Muburyo bwo gushushanya ubushyuhe, igishushanyo mbonera gishobora gukorwa ukurikije ingano. Isano iri hagati yo gushyushya wattage nubunini irerekanwa gutya: LogV = 1.4 X IogW-0.8, aho, Agaciro ntarengwa ka V ni 1.5 kubic santimetero.
2. Igishushanyo mbonera cyo hepfo yaubushyuhe
Muburyo bwo gushushanya ubushyuhe, ubushyuhe bwabwo bwo hasi bugira ingaruka zikomeye kumikorere yubushyuhe.Kugirango imbaraga zubushyuhe zishobora kwanduzwa mumababa yose, birakenewe ko harebwa niba munsi yubushyuhe bwumubyimba mwinshi bihagije, kugirango amababa akoreshwe byuzuye.Nyamara, umubyimba wo hasi ntabwo ubyimbye neza.Niba ari umubyimba mwinshi, bizatera imyanda myinshi, byongere ibiciro, kandi icyarimwe, bizatera kwirundanya ubushyuhe, bigabanye ubushobozi bwo kohereza ubushyuhe.Mugihe ushushanya ubunini bwikibanza cya heatsink, igice cyinkomoko yubushyuhe kigomba kugira umubyimba mwinshi, mugihe igice cyuruhande kigomba kuba gito, kugirango icyuma gishyuha gishobora kwinjiza vuba ubushyuhe hafi yisoko ryubushyuhe, hanyuma kikimururutsa. agace kugirango ugere ku bushyuhe bwihuse.Isano iri hagati yubushyuhe bwo gukwirakwiza wattage nubunini bwo hasi nuburyo bukurikira: t = 7xlogW-6.
3. Kurangiza Igishushanyo mbonera cyubushyuhe
Imbere yubushyuhe, ihererekanyabubasha rikorwa ahanini na convection hamwe nimirasire, muribyo convection bifite igice kinini.Ukurikije iyi miterere, ibintu bitatu bigomba kwitabwaho mugushushanya amababa: icya mbere, igishushanyo mbonera cya fin.Kugirango habeho guhuza neza hagati yimisozi, intera igomba kubikwa hejuru ya 4mm, ariko ntigomba kuba nini cyane.Kinini cyane bizagabanya umubare wudusimba dushobora gushyirwaho, bizagira ingaruka kumwanya wo gukwirakwiza ubushyuhe, Ingaruka zo gukwirakwiza ubushyuhe ziragerwaho.Icyakabiri, igishushanyo mbonera cya fin, inguni ya fin ni nka dogere eshatu, nziza.Hanyuma, nyuma yo kumenya ubunini nuburyo bwa fin, uburinganire bwuburebure nuburebure biba ngombwa cyane.
Usibye hejuru yubushakashatsi bwibishushanyo mbonera, Iyo duhuye nimishinga yihariye, dukeneye isesengura ryihariye no gukoresha byoroshye ubumenyi bwa tekiniki kugirango dutange ubushyuhe bukabije
