Uyilo lweisinki yobushushusesona sigqibo sibalulekileyo sokuchitha ubushushu kwisinki yobushushu.Ngokwembono yenkqubo yokutshatyalaliswa kobushushu, yahlulwe ngokubanzi ngamanyathelo amathathu:ukufunxa ubushushu, ukuqhuba ubushushu kunye nokutshatyalaliswa kobushushu.Ke ngoko, uyilo lwe-heat sink kufuneka luqale ngala manyathelo mathathu okuphucula ukusebenza kokufunxa ubushushu, ukuqhutywa kobushushu kunye nokutshatyalaliswa kobushushu ngokulandelelanayo, ukuze kufumaneke isiphumo esingcono sokuphelisa ubushushu.Impahla yokuvelisa i-heat sink yinto ebalulekileyo echaphazela ukusebenza kakuhle, okufuneka ihlawulwe ingqalelo xa ukhetha, kodwa izinto eziphathekayo zokushisa azikwazi ukumisela ukusebenza kwayo yonke.Eyona nto yokuphucula ukusebenza kwesitya sokushisa kuyilo lwemveliso.
Umgaqo-siseko woYilo weSinki yoBubushushu
Xa uyila i-heat sink kwiimveliso ze-elektroniki, yeyona ndlela iqhelekileyo yokusebenzisa ukuchasana kwe-thermal ukuyila.Inkcazelo yokumelana ne-thermal yile: R=△T/P.
△ I-T ithetha umahluko wobushushu, ngelixa i-P imele amandla okusebenzisa ubushushu kwitshiphu.Ukuxhatshazwa kwe-thermal kubonisa ubunzima bokudlulisa ukushisa kwesixhobo.Ixabiso elikhulu, libi kakhulu ifuthe lokutshatyalaliswa kobushushu besixhobo, kunye nexabiso elincinci, kulula ukuchithwa kobushushu.
Izikhokelo zoYilo Jikelele lweSinki yobushushu
1. Uyilo lomthamo we-heat sink
Umthamo we-heat sink uthetha umthamo ogcinwe yi-heat sink.Ngokubanzi, amandla amakhulu okufudumeza kweemveliso ze-elektroniki, mkhulu umthamo wesitya sobushushu esifunekayo.Kwinkqubo yoyilo lwe-heat sink, uyilo lwangaphambili lunokwenziwa ngokomthamo.Ubudlelwane phakathi kokufudumeza kwamanzi kunye nomthamo kuboniswa ngolu hlobo lulandelayo: LogV = 1.4 X IogW-0.8, apho, Ixabiso elincinci le-V yi-1.5 cubic iisentimitha.
2. Uyilo lobunzima bomzantsi weisinki yobushushu
Kwinkqubo yokuyila i-heat sink, ubukhulu bayo obuphantsi bunempembelelo enkulu ekusebenzeni kokuchithwa kobushushu.Ukuze wenze amandla obushushu adluliselwe kuzo zonke iifins, kuyimfuneko ukuqinisekisa ukuba i-bottom ye-heat sink inzima ngokwaneleyo, ukwenzela ukuba i-fins isetyenziswe ngokupheleleyo.Nangona kunjalo, ubukhulu bomzantsi abukho ngcono ngakumbi.Ukuba kukhulu kakhulu, kuya kubangela inkunkuma enkulu yezinto eziphathekayo, ukunyuka kweendleko, kwaye kwangaxeshanye, kuya kubangela ukuqokelelwa kobushushu, ukunciphisa umthamo wokudlulisa ubushushu.Xa uyila ubukhulu bomzantsi we-heatsink, indawo yomthombo wobushushu kufuneka ibe nobukhulu obukhulu, ngelixa indawo esecaleni kufuneka ibe ncinci, ukuze i-heatsink ikwazi ukufunxa ngokukhawuleza ubushushu kufutshane nomthombo wobushushu, kwaye uyidlulisele kumntu obhityileyo. indawo yokufezekisa ukutshatyalaliswa kobushushu ngokukhawuleza.Unxulumano phakathi kwamanzi okuphelisa ubushushu kunye nobungqingqwa obusezantsi buhamba ngolu hlobo lulandelayo: t=7xlogW-6.
3. Fin Shape Design of the heat sink
Ngaphakathi kwi-heat sink, ukuhanjiswa kobushushu kuqhutyelwa ikakhulu nge-convection kunye ne-radiation, apho i-convection ibala umlinganiselo omkhulu.Ngokusekwe kolu hlobo, imiba emithathu kufuneka iqwalaselwe kuyilo lwamaphiko: okokuqala, uyilo lwesithuba se-fin.Ukuqinisekisa ukuhamba kakuhle phakathi kwamaphiko, izithuba kufuneka zigcinwe ngaphezu kwe-4mm, kodwa akufanele zibe zikhulu kakhulu.Inkulu kakhulu iya kunciphisa inani lee-fins ezinokuthi zibekwe, eziza kuchaphazela indawo yokutshatyalaliswa kobushushu, Isiphumo sokutshatyalaliswa kobushushu sichaphazelekayo.Okwesibini, uyilo lwe-engile ye-fin, i-angle ye-fin malunga needigri ezintathu, ngcono.Ekugqibeleni, emva kokumisela ubukhulu kunye nokuma kwe-fin, ibhalansi yobunzima kunye nokuphakama kwayo kubaluleke kakhulu.
Ngaphandle kwezikhokelo zoyilo lweziko ezingaphezulu kobushushu, Xa sidibana neeprojekthi ezithile, sifuna uhlalutyo olukhethekileyo kunye nokusetyenziswa okuguquguqukayo kolwazi lobugcisa ukubonelela ngesinki yobushushu esebenzayo.
