UKUKHETHWA KWE-HEATSINK EFANELEKILEYO YOKUPHOLISA AMANDLA ISIXHOBO SE-SEMICONDUCTOR

1. Indibano yokupholisa amanzi ye-heat sink kunye nesixhobo

Indlela yokupholisa yeendibano ibandakanya ukupholisa kwendalo kunye ne-heat sink, ukupholisa umoya okunyanzelekileyo kunye nokupholisa kwamanzi.Ukuze isixhobo sisebenzise ukusebenza okulinganiselwe ngokuthembekileyo kwisicelo, kuyimfuneko ukukhetha efanelekileyoamanzi okupholisa heatsinkkwaye uyidibanise nesixhobo ngokufanelekileyo.Enjalo ukuqinisekisa ukuxhathisa thermal Rj-hs phakathi isinki ubushushu kunye thyristor / diode chip idibana imfuneko yokupholisa.Imilinganiselo kufuneka ithathelwe ingqalelo ngolu hlobo lulandelayo:

1.2 Ukuba mcaba kunye nokucoceka kwendawo yokudibanisa i-heat sink kufuneka igqitywe kakhulu.Kucetyiswa ukuba uburhabaxa bomphezulu bombhobho wobushushu bungaphantsi okanye bulingana no-1.6μm, kwaye ukucaba kungaphantsi okanye kulingane ne-30μm.Ngexesha lokudibanisa, indawo yoqhagamshelwano yesixhobo kunye ne-heat sink kufuneka ihlale icocekile kwaye ingenayo ioli okanye enye inkunkuma.

1.3 Qinisekisa ukuba indawo yoqhagamshelwano yesixhobo kunye nesinki yobushushu ingqamene kwaye igxile.Ngethuba lokuhlanganisana, kuyimfuneko ukusebenzisa uxinzelelo ngokusebenzisa i-centerline yecandelo ukwenzela ukuba i-press force isasazwe ngokulinganayo kuyo yonke indawo yoqhagamshelwano.Ekuhlanganiseni ngesandla, kucetyiswa ukuba kusetyenziswe i-torque wrench ukuze kufakwe amandla kunye nawo onke amantongomane aqinisiweyo, kwaye uxinzelelo kufuneka luhlangabezane nedatha ecetyiswayo.

1.4 Nceda unike ingqwalaselo ethe kratya ukujonga indawo yoqhagamshelwano icocekile kwaye ithe tyaba ukuba uyaphinda usebenzisa isinki yokupholisa ubushushu bamanzi.Qinisekisa ukuba akukho sikali okanye ukuvaleka kumngxuma webhokisi yamanzi, kwaye ngakumbi akukho kugoba kwindawo yoqhagamshelwano.

2. Uqwalaselo kunye neemodeli zeheatsink

Ngokwesiqhelo siya kusebenzisa uthotho lwe-SS olupholileyo lwamanzi kunye nochungechunge olupholileyo lomoya lwe-SF kunye necandelo elikhethekileyo le-heatsink yokwenza ngokwezifiso ukupholisa izixhobo ze-semiconductor yamandla.Nceda bhekisa kwitheyibhile engezantsi yeemodeli eziqhelekileyo zeheatsink eziqwalaselweyo nezicetyiswayo ngokomndilili wemeko yangoku yezixhobo.

ISF series air-ipholile heatsinkikhethwe phantsi kwemeko yokupholisa umoya ngenkani (isantya somoya ≥ 6m / s), kwaye umthengi kufuneka akhethe ngokweyona mfuneko yokutshatyalaliswa kobushushu kunye nokuthembeka.Ngokubanzi akukhuthazwa ukusebenzisa iheatsink epholileyo ngomoya ukupholisa isixhobo esingaphezulu kwe-1000A.Ukuba iradiyetha epholileyo isetyenziswe ngokwenene, umbane olinganisiweyo wesixhobo kufuneka uncitshiswe ekusebenzeni.Ukuba akukho zidingo ezikhethekileyo zesicelo, i-heatsink idla ngokukhethwa ngokuhambelana nomgangatho oqhelekileyo.Ukuba nayiphi na imfuneko ekhethekileyo evela kumthengi, nceda uqhagamshelane nathi uzive ukhululekile.

3. Ingcebiso

Umba obaluleke kakhulu wokuqinisekisa ukusebenza okuthembekileyo kwesekethe kukukhetha isixhobo esifanelekileyo kunye ne-heat sink.Iamandla aphezulu thyristorkwayeidiode yamandla aphezulueyenziwe yi-Runau Semiconductor ikhanya kakhulu kumgca we-frequency applications.Amandla ombane abonakalisiweyo avela kwi-400V ukuya kwi-8500V kunye noluhlu lwangoku ukusuka kwi-100A ukuya kwi-8KA.Igqwesileyo kwi-pulse eyomeleleyo yesango lokuvusa, ibhalansi entle yokuqhuba kunye neempawu zokubuyisela.Isitya sokupholisa amanzi sokupholisa siyilwe kwaye senziwa ngamaziko e-CAD kunye ne-CNC.Kuyanceda ukuphucula ukusebenza kwezixhobo.
