Amasinki okushisa e-pin fin asetshenziswa kakhulu ezimbonini ezahlukahlukene, kufaka phakathi imakethe ye-IGBT (Insulated Gate Bipolar Transistor).Lawa masinki okushisa adlala indima ebalulekile ekusizeni ukuqeda ukushisa okukhiqizwa ama-IGBT, ukuqinisekisa ukusebenza kwawo okuphelele nokuthembeka.Kulesi sihloko, sizohlolaimakethe ye-pin fin heat sink yama-IGBTs, amandla ayo okukhula, kanye nezitayela ezivelayo.
Imakethe ye-IGBT ibilokhu ibona ukukhula okuphawulekayo eminyakeni yamuva, ikakhulukazi ngenxa yesidingo esikhulayo samadivayisi kagesi ahlangene futhi asebenza kahle emikhakheni efana nezimoto, ugesi wabathengi, amandla avuselelekayo, kanye nezicelo zezimboni.Njengoba lawa madivayisi aphatha amandla aphezulu kanye namazinga amanje, akhiqiza ukushisa okukhulu, okudinga ukuchithwa ngokuphumelelayo ukuze kuvinjelwe ukushisa ngokweqile nokuqinisekisa ukusebenza kahle.
Enye yezindlela eziphumelela kakhulu nezivame ukusetshenziswa zokukhipha ukushisa kwama-IGBT yipin fin ukushisa usinki.Lawa masinki okushisa ahlanganisa iqoqo lezikhonkwane eziningi ezincane eziphuma ku-base plate.Lawa maphini akhulisa indawo engaphezulu etholakalayo yokudluliswa kokushisa, okuthuthukisa umthamo wokupholisa usuwonke we-sink yokushisa.
Imakethe ye-pin fin heat sink ye-IGBTs kulindeleke ukuthi ibone ukukhula okukhulu eminyakeni ezayo.Isidingo esikhulayo samadivayisi kagesi kagesi, okuhambisana nesidingo sezixazululo zokupholisa ezithuthukisiwe, kuqhuba imakethe.Ukwengeza, ukuthembela okwandayo kuma-IGBT emikhakheni efana nezimoto zikagesi nezinhlelo zamandla avuselelekayo kuqhubezela phambili isidingo samasinki okushisa amaphinikhodi.
Abadlali abaningana ababalulekile bayasebenza emakethe ye-pin fin heat sink yama-IGBTs, okuhlanganisa i-Famos Tech.Lezi zinkampani zigxile ekuthuthukiseni izixazululo ezintsha nezisebenza kahle kakhulu zokubhekana nezidingo ezithile zemakethe ye-IGBT.
Amathrendi asafufusa emakethe ye-pin fin heat sink yama-IGBT afaka ukwamukelwa kwezinto ezithuthukile kanye nobuchwepheshe bokukhiqiza.Ukusetshenziswa kwezinto ezine-conductivity ephakeme yokushisa, njengethusi ne-aluminium alloys, kuvumela ukuchithwa okungcono kokushisa.Ngaphezu kwalokho, amasu okukhiqiza athuthukile, njengokukhiqiza okungeziwe noma ukuphrinta kwe-3D, anika amandla ukukhiqizwa kwemiklamo eyinkimbinkimbi neyenziwe ngokwezifiso yesinki yokushisa eklanyelwe izinhlelo zokusebenza ezithile ze-IGBT.
Omunye umkhuba emakethe ukwenziwa kweminiaturization kwamasinki okushisa e-pin fin.Ngokucindezela okungaguquki kwamadivayisi kagesi ahlangene futhi angasindi, kunesidingo esikhulayo samasinki amancane okushisa.Abakhiqizi bagxile ekuthuthukiseni amasinki okushisa amaphinikhodi amancane agcina ukusebenza kahle kokushisa okuphezulu kuyilapho ethatha isikhala esincane.
Ngaphezu kwalokho, ukuhlanganiswa kwezici ezengeziwe kumasinki okushisa e-pin fin kuthola amandla.Isibonelo, amanye amasinki okushisa manje ahlanganisa amapayipi okushisa noma amakamelo omusi ukuze kuthuthukiswe amandla awo okupholisa.Lobu buchwepheshe buvumela ukudluliswa kokushisa okuphumelelayo kumabanga amade, bunikeza ukuphathwa okungcono kokushisa kwama-IGBT.
Sengiphetha, imakethe ye-pin fin heat sink ye-IGBTs ilungele ukukhula okubalulekile eminyakeni ezayo.Isidingo esandayo samadivayisi kagesi kagesi, okuhambisana nesidingo sezixazululo ezisebenzayo zokupholisa, kuqhuba ukwanda kwemakethe.Abadlali abamqoka embonini bagxile ekuthuthukiseni izixazululo ze-sink zokushisa ezinikeza ukusebenza okushisayo okuthuthukisiwe nezinketho zokwenza ngokwezifiso.Amathrendi asafufusa, njengokwamukelwa kwezinto ezithuthukile nobuchwepheshe bokukhiqiza, kanye nokwenza kancane kanye nokuhlanganiswa kwezici ezengeziwe, kuzololonga ikusasa lemakethe ye-pin fin heat sink yama-IGBT.
Izinhlobo Zokushiswa Kokushisa
Ukuze kuhlangatshezwane nezidingo ezihlukene zokukhipha ukushisa, imboni yethu ingakhiqiza osinki bezinhlobo ezahlukene zokushisa abanenqubo eminingi ehlukene, njengangezansi:
