1. Madzi ozizira msonkhano wa sinki kutentha ndi chipangizo

Kuzizirira kwa misonkhano kumaphatikizapo kuziziritsa kwachilengedwe ndi sink ya kutentha, kuziziritsa mpweya mokakamiza komanso kuziziritsa madzi.Kuti chipangizochi chigwiritse ntchito modalirika pakugwiritsa ntchito, ndikofunikira kusankha choyeneramadzi ozizira heatsinkndi kusonkhanitsa ndi chipangizo bwino.Izi zimatsimikizira kukana kwamafuta a Rj-hs pakati pa sinki ya kutentha ndi thyristor/diode chip kumakwaniritsa zofunika kuzizira.Miyezo iyenera kuganiziridwa motere:

1.1 Malo okhudzana ndi kutentha kwa kutentha ayenera kufanana ndi kukula kwa chipangizo kuti asawonongeke kapena kuwonongeka kokhotakhota kwa chipangizocho.

1.2 Kusalala ndi kuyera kwa malo olumikizirana ndi kutentha kuyenera kumalizidwa kwambiri.Ndikoyenera kuti roughness ya pamwamba pa sinki ya kutentha ikhale yocheperapo kapena yofanana ndi 1.6μm, ndipo kutsetsereka kumakhala kochepa kapena kofanana ndi 30μm.Pamsonkhano, malo olumikizirana ndi chipangizocho ndi choyakira chotenthetsera chizikhala choyera komanso chopanda mafuta kapena zinyalala zina.

1.3 Onetsetsani kuti malo olumikizirana ndi chipangizocho ndi chotengera cha kutentha ndizofanana komanso zokhazikika.Pamsonkhano, m'pofunika kugwiritsa ntchito kukakamiza kupyolera pakati pa chigawocho kuti mphamvu yosindikizira igawidwe mofanana pa malo onse okhudzana.Posonkhanitsa pamanja, tikulimbikitsidwa kugwiritsa ntchito wrench ya torque kuti mugwiritse ntchito ngakhale mphamvu ku mtedza onse omangirira motsatana, ndipo kukakamiza kuyenera kukwaniritsa zomwe zikuyenera.

1.4 Chonde samalani kwambiri kuti muwonetsetse kuti malo olumikiziranawo ndi oyera komanso athyathyathya ngati mubwerezanso kugwiritsa ntchito sinki yoziziritsira kutentha kwamadzi.Onetsetsani kuti palibe sikelo kapena kutsekeka m'bokosi lamadzi, ndipo makamaka osagwedezeka pamalo olumikizana.

1.5 Chojambula chojambula cha sinki yoziziritsira madzi

2. Kukonzekera ndi zitsanzo za heatsink

Nthawi zambiri tidzagwiritsa ntchito mndandanda wa SS woziziritsidwa ndi madzi ndi mndandanda wa SF woziziritsidwa ndi mpweya komanso magawo osiyanasiyana apadera a heatsink kuti aziziziritsa zida za semiconductor.Chonde onani tebulo ili m'munsimu la mitundu yodziwika bwino ya heatsink yomwe imakonzedwa ndikuvomerezedwa molingana ndi momwe zida ziliri pano.

TheSF mndandanda woziziritsa mpweya woziziraamasankhidwa pansi pa chikhalidwe cha kukakamizidwa mpweya kuziziritsa (mphepo liwiro ≥ 6m/s), ndipo kasitomala ayenera kusankha malinga ndi kwenikweni kutentha dissipation chofunika ndi kudalirika.Nthawi zambiri sizovomerezeka kugwiritsa ntchito heatsink yoziziritsidwa ndi mpweya kuziziritsa chipangizocho pamwamba pa 1000A.Ngati radiator yoziziritsidwa ndi mpweya ikugwiritsidwa ntchito, mphamvu yamagetsi ya chipangizocho iyenera kuchepetsedwa ngati ikugwiritsidwa ntchito.Ngati palibe zofunikira zapadera pakugwiritsa ntchito, heatsink nthawi zambiri imasankhidwa molingana ndi kasinthidwe koyenera.Ngati chofunikira chilichonse chapadera kuchokera kwa kasitomala, chonde lemberani omasuka.

3. Malangizo

Chinthu chofunika kwambiri kuti muwonetsetse kuti ntchito yodalirika ya dera ndiyo kusankha chipangizo choyenerera komanso chozama cha kutentha.Thethyristor yamphamvu kwambirindimkulu mphamvu diodeopangidwa ndi Runau Semiconductor amawunikira kwambiri pamagwiritsidwe pafupipafupi.Magetsi omwe ali nawo amachokera ku 400V mpaka 8500V ndipo amachokera ku 100A mpaka 8KA.Ndibwino kwambiri mu mphamvu yachipata choyambitsa pulse, kulinganiza bwino kwa machitidwe ndi kuchira.Madzi ozizira otentha otentha amapangidwa ndikupangidwa ndi zida za CAD ndi CNC.Ndizothandiza kupititsa patsogolo magwiridwe antchito a zida.
