Amandla aphezulu IGBT Aluminiyam Heat Sink

Isilawuli seMoto esifakwe kwiSango leBipolar Transistor (iSango eliNgenelweyo leBipolar Transistor, i-IGBT) ukusebenza kobushushu bokutshatyalaliswa kobushushu kuya ngokuya kuba yimoto ye-IGBT ngoku ingena kwimarike yombane yamandla eshishini, efana (i-welding) isinki yobushushu, i-inverter ye-traction, i-motor drive, njl.Ruiqifenginikeza iimveliso zendibano ye-IGBT ye-sinki yobushushu evumela ukuba i-IGBT isebenze kwindawo ebiyelweyo yobushushu ngelixa igcina ubushushu besiphambuka sokusebenza ngaphakathi koluhlu olukhuselekileyo ngokudibanisa ukuxhathisa okuphantsi kwe-thermal kunye ne-Vce (on) lesilicon.

I-IGBT kwiimeko ezininzi isebenza ngesixhobo esinamandla aphezulu, amandla aphezulu athetha ukuchithwa kobushushu obuphezulu, i-IGBT ibhekiselele kumthamo omkhulu, i-frequency ephezulu, kulula ukuyiqhuba, ilahleko ephantsi, imodyuli, ibonisa indlela yophuhliso, xa kuthelekiswa nezinye izixhobo zombane zamandla, I-IGBT yokushisa ubushushu inokuthembeka okuphezulu, i-drive elula, kulula ukuyikhusela, akukho sekethi ye-buffer kunye nokutshintsha rhoqo kuphezulu, ngoko ke i-IGBT yokushisa i-IGBT kwimarike ye-elektroniki iba yimfuneko kakhulu.Ukuze kuphunyezwe ezi ntsebenzo eziphezulu, iinkqubo ezininzi zisetyenziselwa kwiisekethe ezidibeneyo, ezifana ne-epitaxy, i-ion implantation, i-lithography emihle, njl.njl Kwiminyaka yakutshanje, ukusebenza kwemodyuli ye-IGBT yemodyuli yokushisa kuphuculwe ngokukhawuleza, ukulinganisa ngoku ifikelele kumakhulu e-amperes, amandla ombane okumelana ne-1500V, kwaye isaphucuka.Ekubeni izixhobo ze-IGBT zineempawu ezintle ze-PIN diode, iimpawu ze-p-channel power IGBT imodyuli yokushisa i-sink ayifani kakhulu naleyo ye-IGBT ye-n-channel, ekulungele kakhulu ukwamkela ulwakhiwo oluncedisayo kwisicelo, ngaloo ndlela ukwandisa. ukusetyenziswa kwayo kwintsimi ye-ac kunye neteknoloji yokulawula idijithali.Olona ncedo lukhulu lwe-IGBT kukuba inokumelana nokothuka kwangoku nokuba kukwimo okanye kwimo yesekethe emfutshane.Uqhagamshelo lwayo olunxuseneyo aluyongxaki kwaye uqhagamshelo lwayo lulula ngenxa yokulibaziseka okufutshane.

Iimowudi zokudlulisa ubushushu be-IGBT zihlala zibandakanya ukupholisa umoya, ukupholisa amanzi, isinki yobushushu yobhedu okanye isinki yobushushu be-aluminium.Ukutshatyalaliswa kobushushu bayo kusekelwe kumgaqo osisiseko wokutshintshwa kobushushu, indlela yokuhamba kobushushu kunye neyona ndlela iphantsi yokumelana ne-thermal yenzelwe isixhobo ukwenzela ukuba ubushushu obukhutshwe sisixhobo bukhutshwe ngokukhawuleza, ukwenzela ukuba kuqinisekiswe ukuba ngaphakathi. Ubushushu besiphambuka sesixhobo buhlala bugcinwe ngaphakathi kweqondo lokushisa elivumelekileyo lokuhlangana.

Okwangoku, i-IGBT ekhoyo yombhobho wobushushu isinki yobushushu kwimarike ikakhulu ibandakanya ubushushu fin yokuchitha, umbhobho ubushushu kunye substrate, apho substrate ibonelelwa ngenani imijelo parallel, kwaye ke umjelo udityaniswe ngesolder ukuya kwicandelo ukuphuphuma. umbhobho wobushushu.Kwi-IGBT ekhoyo yombhobho wokushisa we-teknoloji ye-sink, icandelo elikhuphayo lombhobho wobushushu lingcwatywa kwi-groove ye-substrate kwaye ayihambelani ngqo nomphezulu we-IGBT.Kwinkqubo yokusebenza, ukushisa okuvela kwindawo ye-IGBT kuqala kuthunyelwa ngaphandle nge-substrate kwaye emva koko idluliselwe kumbhobho wokushisa kunye ne-heat sink.Ekugqibeleni, ubushushu obuvela kwi-heat sink budluliselwa emoyeni nge-convection.Ngenxa yokuba i-substrate ngokwayo inokumelana ne-thermal, kwaye i-coefficient conductivity ye-thermal yombhobho wokushisa iphezulu kakhulu kunesiseko, i-thermal conductivity ye-thermal conductivity ye-thermal pipe ye-heat sink iyancipha, kwaye ukusebenza kokutshatyalaliswa kobushushu kuyancipha.I-IGBT ye-heat sink inokudlulisa ubushushu ngokulinganayo ukusuka kwi-substrate ukuya kwi-fin, enokusombulula ngokufanelekileyo ingxaki yokutshatyalaliswa kobushushu bobushushu obuphezulu, kungekhona nje ngokusebenza okuphezulu kodwa kunye nesakhiwo esihlangeneyo kwaye akukho malungu ahambayo, anokuqonda ngokwenene ukugcinwa- simahla.
