Idatha Iyathetha | I-YMIN VHE capacitors iyisombulula njani imingeni yobushushu obuphezulu kunye ne-ripple ephezulu yeenkqubo zolawulo lwe-automotive thermal?

Intshayelelo

Kwiinkqubo zolawulo lwe-thermal yesithuthi sombane, ii-activators ezifana neempompo zamanzi ze-elektroniki, iimpompo ze-oyile, kunye neefeni zokupholisa zihlala zisebenza kwiindawo ezinobushushu obuphezulu kunye ne-high-vibration. Ii-capacitors ze-aluminiyam ze-aluminiyam eziqhelekileyo ziyakwazi ukulawula ukungasebenzi kakuhle kwebhodi kunye nokungaphumeleli kwenkqubo ngenxa yokunyuka kwe-ESR kunye nokunganyamezeli kwe-ripple eyaneleyo.

YMIN Isisombululo

I-Capacitors ifumana ukomiswa kwe-electrolyte kunye nokuthotywa komgangatho we-oxide kwiindawo ezinobushushu obuphezulu, okukhokelela ekwandeni kwe-ESR, ukuthotywa kwe-capacitance, kunye nokuvuza kwangoku. Ngokukodwa kwizixhobo zombane ezitshintsha rhoqo, ukufudumeza okubangelwa yiripple yangoku kukhawulezisa ukwaluphala.

Uthotho lwe-VHE lusebenzisa isizukulwana esilandelayo se-polymer hybrid dielectric kunye noyilo lwesakhiwo se-electrode ukuphumeza:

I-ESR ephantsi: Uluhlu olutsha lwe-VHE lugcina ixabiso le-ESR le-9-11 mΩ (ingcono kune-VHU enokuguquguquka okuncinci), okukhokelela ekulahlekeni okuphantsi kobushushu kunye nokusebenza okuhambelanayo.

I-High Ripple Current Capacitance: I-VHE series 'ripple current handling capability ingaphezulu kwe-1.8 amaxesha aphezulu kune-VHU, inciphisa kakhulu ilahleko yamandla kunye nokuveliswa kobushushu. Ngokufanelekileyo ifunxa kwaye ihluze i-ripple yangoku ephezulu eveliswa yi-motor drive, ukukhusela ngokufanelekileyo i-activator, ukuqinisekisa ukusebenza okuqhubekayo kunye nozinzo, kunye nokucinezela ngokufanelekileyo ukuguquguquka kwamandla ombane ekuphazamisekeni kumalungu ajikelezayo.

Ukumelana nobushushu obuphezulu

Iiyure ezingama-4000 zobomi benkonzo kwi-135 ° C kwaye ixhasa amaqondo obushushu ambi ukuya kuthi ga kwi-150 ° C; imelana ngokulula nawona maqondo obushushu asebenzayo aphakathi kwindawo yenjini.

Ukuthembeka okuphezulu

Xa kuthelekiswa nochungechunge lwe-VHU, uchungechunge lwe-VHE lubonelela ngokugqithiswa okuphuculweyo kunye nokumelana nokothuka, ukuqinisekisa ukusebenza okuzinzileyo phantsi komthwalo ogqithisiweyo okanye iimeko zokothuka. Intlawulo yayo egqwesileyo kunye nokuchaswa kokukhutshwa kulungelelaniswa ngokulula neemeko zokusebenza eziguquguqukayo ezifana nokuyeka rhoqo kunye nemijikelo yokuyeka, iqinisekisa ubomi obude benkonzo.

Ukuthembeka kweDatha yoQinisekiso kunye neeNgcebiso zokuKhetha

Idatha yovavanyo ibonisa ukuba uchungechunge lwe-VHE ludlula abakhuphisana bamazwe ngamazwe kwiimpawu ezininzi zokusebenza:

I-ESR iyancipha ukuya kwi-8-9mΩ (eqhelekileyo);

Ikhono langoku le-Ripple lifikelela kwi-3500mA kwi-135 ° C;

I-voltage yokunyamezela ifikelela kwi-44V;

I-Capacitance kunye nokwahluka kwe-ESR kuncitshiswe kuluhlu olubanzi lobushushu.

-Imeko yeSicelo kunye neeModeli eziCetyisiweyo -

Uluhlu lwe-VHE lusetyenziswa ngokubanzi kubalawuli bolawulo lwe-thermal (iipompo zamanzi / iimpompo zeoli / abalandeli) kunye neesekethe zokuqhuba iimoto.
Iimodeli ezicetyiswayo zigubungela ubume bomthamo obuninzi ukusuka kwi-25V ukuya kwi-35V, zixinene ngobukhulu, kwaye zibonelela ngokuhambelana okuqinileyo.

Thatha iVHE 135°C 4000H njengomzekelo:

Ukuqukumbela

Uluhlu lwe-VHE lwe-YMIN luphucula kakhulu ukusebenza kwe-capacitor kwiqondo lokushisa eliphezulu, kwiindawo eziphakamileyo eziphezulu ngokusebenzisa izinto ezintsha kunye nezakhiwo. Ibonelela ngesisombululo esithembeke kakhulu kwiinkqubo zolawulo lwemoto yamandla amatsha, inceda ishishini ukuba lihambe liye kulwakhiwo lombane olusebenzayo noluzinzileyo kwisizukulwana esilandelayo.
