Ceramic Heat Sink

Tsanangudzo Pfupi:

Ceramic heat sink inonyanya kuumbwa neaya yekupisa kupisa uye yekupisa conduction layer, iyo yekupisa yekupisa layer ndeye kushandiswa kwemvura chikamu chemakemikari shanduko musimboti kune latex slurry kusaenzana kupararira, kuumbwa kweceramic poda yakaonda chimiro, uye yakasanganiswa ne sub-micron. hupfu, uye yobva yapiswa mugomba rekristaro mhango chimiro chekupisa kupisa, iyo porosity yeiyo micro cavity chimiro chekupisa kwekupisa layer pakati pe5% ne40%, Hukuru hwehupfu huri pakati pe90 nm ne300 nm.Iyo yekubata kumeso ine inopisa sosi ine thermal conductivity layer, inotora uye inoitisa kupisa sosi.Kuburikidza nepamusoro pepamusoro pechimiro cheporous chekupisa kwekushisa, simba rekupisa rinogadziriswa rinovandudzwa nekushandisa mhepo semhepo inopisa inopisa.

Ceramic heat sink chigadziro chinobvisa kupisa kubva kune zvinopisa zvinopisa zvemagetsi zvemudziyo wemagetsi.Parizvino, iyo inowanzoshandiswa alumina zvedongo pepa, aruminiyamu nitride zvedongo pepa, nesilicon carbide zvedongo sheet.

Alumina ceramic sheet: Iine hutano hwepamusoro hwekushisa, kupisa kwekushisa: 24W / MK, kupisa kwepamusoro / kupikisa kwepamusoro, kupisa zvakaenzana, kukurumidza kupisa kupera.Pamusoro pezvo, ine yakapfava uye compact chimiro, diki saizi, yakatsetseka pamusoro, yakakwirira simba uye haisi nyore kutyora, asidhi uye alkali corrosion resistance, yakasimba.

Aluminium nitride ceramic sheet:Ruvara i grey chena, yakatsetseka pamusoro, inogona kugadzirwa mune chero chimiro kana saizi, iri nyore kushandisa uye kuisa.Iyi ceramic radiator ine yakanyanya kupisa conductivity, thermal conductivity ndeye 7-10 nguva yealumina ceramic sheet, inogona kusvika 180W yakakwirira, kushanda kwayo kwemagetsi ekudzivirira kwakagadzikana, dielectric inogara uye kurasikirwa kwepakati kwakaderera, inogona kumira 1800 degrees Celsius uye. haikanganisi kushanda kwechigadzirwa.Nekukurumidza kukura kwemidziyo yemagetsi, kudiwa kwezvigadzirwa zvemagetsi kana zvekubatsira kuri kuwedzera, uye chiyero chekushandiswa kwechigadzirwa ichi senge yakakwira yekupisa conductivity aluminium nitride ceramic sheet sematrix kana zvinhu zvekurongedza zviri kuramba zvichiwedzera mumusika. .

Silicon carbide ceramic sheet: Iyo yakasvibira yekudzivirira kwezvakatipoteredza zvinhu, ndeyeiyo microporous chimiro, munzvimbo imwechete yeyuniti inogona kupfuura 30% porosity, inowedzera zvakanyanya nzvimbo yekupisa yekupisa uye kusangana nemhepo, inosimudzira kupisa kupisa.Panguva imwecheteyo, huwandu hwayo hwekupisa hudiki, kuchengetedza kwayo kupisa kudiki, kupisa kunogona kuendeswa kune imwe nyika nekukurumidza, hunhu hukuru hweceramic heat sink: kuchengetedzwa kwezvakatipoteredza, kuvharira uye kupikisa kwakanyanya, kupisa kunoshanda. , kudzivirira kubereka kweEMI matambudziko.Inogona kugadzirisa zvinobudirira matambudziko ekupisa conduction uye kupisa kupisa mumagetsi nemidziyo yemumba.Panguva imwecheteyo, inonyanya kukodzera kushandiswa kwemagetsi maduku uye epakati.Iyo nzvimbo yekugadzira inoteerera kune yakapfava, yakaonda, pfupi uye diki zvigadzirwa, izvo zvinogona kupa rubatsiro rwehunyanzvi uye kunyorera kwekuvandudza uye kusimudzira zvigadzirwa zvemagetsi.

Zvakanakira

1.Ceramic heat sink inogona zvakananga kupisa kupisa, uye kukurumidza kunonyanya kukurumidza, kuderedza simba rekuvhara denga pamusoro pekushanda kwekushisa;

2.Ceramic heat sink is a polycrystalline structure, chimiro ichi chinogona kusimbisa kupisa kwekushisa, kunze kwemusika zvinhu zvakawanda zvinopisa zvinopisa;

3.Ceramic heat sink inogona kuva yakawanda-directional heat dissipation, kukurumidza kupisa kupisa;

4.Ceramic heat sink's insulation, high thermal conductivity, high voltage resistance, high temperature resistance, kupfeka resistance, high simba, oxidation resistance, acid uye alkali resistance, hupenyu hurefu hwebasa, kuderera kwekuwedzera kwemafuta ekuwedzera kunogona kuve nechokwadi chekugadzikana kweceramic heat sink in. yakakwirira uye yakadzika tembiricha nharaunda kana imwe nzvimbo yakaoma;

5.Ceramic heat sink inogona kunyatso kurwisa-kupindira (EMI), anti-static;

6.Ceramic kupisa kunyura uchishandisa zvinhu zvakasikwa zvakasikwa, zvinosangana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza;

7.Ceramic heat sink's small volume, lightweight, high simba, inogona kuchengetedza nzvimbo, kuchengetedza zvinhu, kuchengetedza kutakura, kunowedzera kurongeka kunonzwisisika kwekugadzirwa kwechigadzirwa;

8.Ceramic heat sink inogona kumira yakakwira ikozvino, yakakwira voltage, inogona kudzivirira kuvuza kuparara, hapana ruzha, haizobudise coupling parasitic capacitance neMOS uye imwe simba chubhu, uye nekudaro kurerutsa nzira yekusefa, inoda iyo creepage kureba ipfupi pane iyo simbi inodiwa nemuviri, inogona kuwedzera kuchengetedza nzvimbo yebhodhi, inokonzeresa dhizaini yeinjiniya uye chitupa chemagetsi.

Nhanganyaya Yekushandisa

Ceramic heat sink inonyanya kushandiswa muzvikamu zvechigadzirwa zvinoda kupisa conduction insulation, senge yakakwirira-simba midziyo, IC MOS chubhu, IGBT chigamba mhando kupisa conduction insulation, yakakwirira-frequency magetsi, kutaurirana, michina michina.Mukuwedzera, ceramic radiator ichashandiswawo mukuvhenekera kwe LED, high frequency welder, simba amplifier / inzwi, simba transistor, magetsi module, chip IC, inverter, network / broadband, UPS magetsi uye zvichingodaro.
