Ceramic Heat Sink

Kufotokozera Kwachidule:

Ceramic kutentha lakuya makamaka wapangidwa ndi kutentha dissipation wosanjikiza ndi kutentha conduction wosanjikiza, kutentha dissipation wosanjikiza ndi ntchito madzi gawo mankhwala kusintha mfundo kuti latex slurry kubalalitsidwa, mapangidwe ceramic ufa woonda dongosolo, ndipo pamodzi ndi sub-micron. ufa, ndiyeno kuthamangitsidwa mu dzenje galasi patsekeke dongosolo kutentha disipation wosanjikiza, ndi porosity wa yaying'ono patsekeke dongosolo la kusanjikiza kutentha disipation pakati 5% ndi 40%, The tinthu kukula kwa ufa ndi pakati 90 nm ndi 300 nm.Kulumikizana pamwamba ndi gwero kutentha ali matenthedwe madutsidwe wosanjikiza, amene amatenga ndi kuchititsa kutentha gwero.Kupyolera mu malo okwera kwambiri a mapangidwe a porous a kutentha kwa kutentha, mphamvu ya kutentha kwapakati imapangidwa bwino pogwiritsa ntchito mpweya monga kutentha kwapakati.

Chombo cha ceramic heat sink ndi chipangizo chomwe chimachotsa kutentha kuchokera kuzinthu zamagetsi zomwe zimakhala ndi kutentha kwa chipangizo chamagetsi.Pakali pano, ambiri ntchito aluminiyamu ceramic pepala, zotayidwa nitride ceramic pepala, pakachitsulo carbide ceramic pepala.

Alumina ceramic pepala: Imakhala ndi kutentha kwakukulu, kutentha kwapakati: 24W / MK, kutentha kwakukulu / kukana kupanikizika, kutentha mofanana, kutentha kwachangu.Kuphatikiza apo, ili ndi mawonekedwe osavuta komanso ophatikizika, kakulidwe kakang'ono, kosalala pamwamba, mphamvu yayikulu ndipo sivuta kusweka, kukana kwa dzimbiri kwa asidi ndi alkali, kukhazikika.

Aluminium nitride ceramic pepala: Mtundu ndi imvi woyera, yosalala pamwamba, akhoza makonda mu mawonekedwe aliwonse kapena kukula, yosavuta kugwiritsa ntchito ndi kukhazikitsa.Radiyeta ya ceramic iyi imakhala ndi matenthedwe apamwamba kwambiri, matenthedwe amatenthedwe ndi nthawi 7-10 ya alumina ceramic pepala, amatha kufika 180W pamwamba, ntchito yake yamagetsi yamagetsi imakhala yokhazikika, dielectric yosasinthika komanso kutayika kwapakatikati ndikotsika, kumatha kupirira madigiri 1800 Celsius ndi sizimakhudza magwiridwe antchito.Ndikukula mwachangu kwa zida zamagetsi, kufunikira kwa zinthu zamagetsi kapena zowonjezera kukuchulukirachulukira, ndipo kuchuluka kwazomwe zimagwiritsidwa ntchito ngati pepala lopangira matenthedwe la aluminiyamu nitride ceramic monga matrix kapena zonyamula katundu zikuchulukirachulukira pamsika. .

Silicon carbide ceramic pepala: Ndi zobiriwira zoteteza zachilengedwe zipangizo, ndi wa dongosolo microporous, m'dera lomwelo unit akhoza kukhala oposa 30% porosity, kwambiri kuonjezera kutentha dissipation dera ndi kukhudzana mpweya, kumapangitsanso kutentha dissipation zotsatira.Panthawi imodzimodziyo, kutentha kwake kumakhala kochepa, kusungirako kutentha kwake kumakhala kochepa, kutentha kumatha kusamutsidwa kudziko lakunja mofulumira, makhalidwe akuluakulu a ceramic kutentha kwakuya: kuteteza chilengedwe, kutsekemera ndi kukana kuthamanga kwapamwamba, kutentha kwachangu. , kupewa kuswana kwa mavuto a EMI.Ikhoza kuthetsa bwino mavuto oyendetsa kutentha ndi kutentha kwa magetsi mu makampani a zamagetsi ndi zipangizo zapanyumba.Panthawi imodzimodziyo, ndizoyenera kwambiri kugwiritsa ntchito mphamvu zamagetsi zazing'ono ndi zapakati.Malo opangirako amatchera khutu ku zinthu zowala, zoonda, zazifupi komanso zazing'ono, zomwe zingapereke chithandizo chaumisiri ndikugwiritsa ntchito kwatsopano ndi chitukuko cha zinthu zamagetsi.

Ubwino wake

1.Ceramic kutentha sink akhoza mwachindunji kutaya kutentha, ndi liwiro mofulumira kwambiri, kuchepetsa chikoka cha kutchinjiriza wosanjikiza pa dzuwa matenthedwe dzuwa;

2.Ceramic kutentha kutentha ndi mawonekedwe a polycrystalline, dongosololi likhoza kulimbikitsa kutentha kwa kutentha, kupyola msika wa zipangizo zotentha kwambiri zotentha;

3.Ceramic kutentha sink ikhoza kukhala yotentha yamitundu yambiri, kufulumizitsa kutentha kwa kutentha;

4. Ceramic heat sink's insulation, high matenthedwe conductivity, high voltage resistance, high heat resistance, wear resistance, high mphamvu, oxidation resistance, asidi ndi alkali kukana, moyo wautali wautumiki, kutsika kwamafuta otsika kungathe kutsimikizira kukhazikika kwa sink ya ceramic kutentha mkati. malo okwera ndi otsika kutentha kapena malo ena ovuta;

Kutentha kwa 5.Ceramic kutentha kungathe kusokoneza bwino (EMI), anti-static;

6.Ceramic kutentha kutentha pogwiritsa ntchito zinthu zachilengedwe zachilengedwe, kukwaniritsa zofunikira za chitetezo cha chilengedwe;

Voliyumu yaying'ono ya 7.Ceramic heat sink, kulemera kopepuka, mphamvu yayikulu, imatha kusunga malo, kusunga zida, kupulumutsa katundu, kumathandizira pakuyika koyenera kwa kapangidwe kazinthu;

8. Ceramic kutentha lakuya akhoza kupirira mkulu panopa, mkulu voteji, angalepheretse kutayikira kuwonongeka, palibe phokoso, sangabweretse kugwirizana parasitic capacitance ndi MOS ndi zina mphamvu chubu, choncho kuphweka ndondomeko kusefa, pamafunika creepage mtunda ndi lalifupi kuposa Zofunikira za thupi lachitsulo, zitha kupulumutsanso malo a board, kukhala othandiza pamapangidwe a akatswiri ndi ziphaso zamagetsi.

Chiyambi cha Ntchito

Ceramic heat sink imagwiritsidwa ntchito makamaka pazinthu zomwe zimafunikira kutentha kwa kutentha, monga zida zamphamvu kwambiri, chubu cha IC MOS, IGBT patch mtundu wa kutentha kwa conduction, magetsi othamanga kwambiri, kulumikizana, zida zamakina.Kuphatikiza apo, radiator ya ceramic idzagwiritsidwanso ntchito pakuwunikira kwa LED, wowotcherera pafupipafupi, amplifier / phokoso, transistor yamagetsi, gawo lamagetsi, chip IC, inverter, network/broadband, magetsi a UPS ndi zina zotero.
