ʻO ka Puʻupuʻu Wela Seramika

ʻO ka wehewehe pōkole:

Hoʻokumu nui ʻia ka ʻōpala wela seramika i kahi papa hoʻoheheʻe wela a me kahi papa hoʻoheheʻe wela, ʻo ka hoʻoheheʻe wela ka hoʻohana ʻana i ka loina hoʻololi kemika wai i ka latex slurry uneven dispersion, ka hoʻokumu ʻana o ka pauka seramika lahilahi, a hui pū me ka sub-micron ka pauda, a laila puhi ʻia i loko o ka lua aniani ʻeleʻele ka hoʻoheheʻe ʻana i ka wela, ka porosity o ka micro cavity structure o ka wela dissipation layer ma waena o 5% a me 40%, ʻO ka nui o ka pauka ma waena o 90 nm a me 300 nm.ʻO ka ʻili pili me ke kumu wela he papa conductivity wela, nāna e hoʻomohu a hoʻokele i ke kumu wela.Ma o ka ʻili kiʻekiʻe o ke ʻano porous o ka papa hoʻoheheʻe wela, hoʻomaikaʻi ʻia ka hiki ke hoʻoheheʻe wela ma o ka hoʻohana ʻana i ka ea ma ke ʻano he mea wela.

ʻO ka puʻu wela seramika kahi mea e hoʻopau ai i ka wela mai nā ʻāpana uila wela o kahi mea uila.I kēia manawa, hoʻohana maʻamau ka alumina ceramic sheet, alumini nitride ceramic sheet, silicon carbide ceramic sheet.

Pepa seramika alumina: He kiʻekiʻe ka wela wela, thermal conductivity: 24W/MK, kiʻekiʻe wela / kiʻekiʻe puʻe kū'ē, wela like 'ole, wikiwiki wela dissipation.Eia kekahi, he mea maʻalahi a paʻa kona ʻano, liʻiliʻi liʻiliʻi, ʻili maʻemaʻe, ikaika kiʻekiʻe a ʻaʻole maʻalahi ka haki ʻana, ka acid a me ka alkali corrosion resistance, lōʻihi.

Aluminum nitride pepa seramika: He keʻokeʻo keʻokeʻo keʻokeʻo, maʻemaʻe ka ʻili, hiki ke hoʻopili ʻia i kekahi ʻano a i ʻole ka nui, maʻalahi e hoʻohana a hoʻokomo.He kiʻekiʻe loa ka conductivity thermal o kēia radiator ceramic, ʻo ka conductivity thermal he 7-10 mau manawa o ka alumina ceramic sheet, hiki ke piʻi i ka 180W kiʻekiʻe, paʻa loa kāna hana insulation uila, haʻahaʻa ka dielectric mau a me ka nalowale waena, hiki ke kū i ka 1800 degere Celsius a ʻaʻole pili i ka hana o ka huahana.Me ka hoʻomohala wikiwiki ʻana o nā lako uila, ke hoʻonui nei ka noi no nā huahana uila a i ʻole nā huahana kōkua, a ʻo ka helu noi o kēia huahana e like me ke kiʻekiʻe thermal conductivity alumini nitride ceramic sheet ma ke ʻano he matrix a i ʻole nā mea hoʻopihapiha e lilo a nui aʻe i ka mākeke. .

ʻO ka pepa silika carbide: He ʻōmaʻomaʻo ia nā mea palekana kaiapuni, no ka microporous structure, ma ka ʻāpana like ʻole hiki ke ʻoi aku ma mua o 30% porosity, hoʻonui nui i ka wahi wela a me ka hoʻopili ʻana i ka ea, hoʻonui i ka hopena dissipation wela.I ka manawa like, he liʻiliʻi kona wela wela, he liʻiliʻi kona mālama wela, hiki ke hoʻololi koke ʻia ka wela i waho o ka honua, nā hiʻohiʻona nui o ka wela seramika: ka mālama ʻana i ke kaiapuni, ka insulation a me ke kūpaʻa kiʻekiʻe, ka hoʻopau wela maikaʻi. , e pale i ka hoʻoulu ʻana o nā pilikia EMI.Hiki iā ia ke hoʻoponopono maikaʻi i nā pilikia o ka lawe ʻana i ka wela a me ka hoʻoheheʻe ʻana i ka wela ma ka ʻoihana uila a me nā mea hana hale.I ka manawa like, kūpono loa ia no ka hoʻohana mana wattage liʻiliʻi.Hoʻomaopopo ka wahi hoʻolālā i nā huahana māmā, lahilahi, pōkole a liʻiliʻi, hiki ke hāʻawi i ke kākoʻo ʻenehana a me ka noi no ka hana hou a me ka hoʻomohala ʻana i nā huahana uila.

Nā pono

Hiki i ka 1.Ceramic heat sink ke hoʻokuʻu pono i ka wela, a wikiwiki loa ka wikiwiki, e hoʻemi ana i ka mana o ka papa insulation ma ka thermal efficiency;

ʻO 2.Ceramic heat sink he hale polycrystalline, hiki i kēia hale ke hoʻoikaika i ka hoʻopau ʻana i ka wela, ma waho o ka mākeke ka nui o nā mea wela wela;

3.Ceramic heat sink hiki ke multi-directional heat dissipation, wikiwiki i ka wela wela;

4.Ceramic heat sink's insulation, high thermal conductivity, high voltage resistance, high temperature resistance, wear resistance, high strength, oxidation resistance, acid and alkali resistance, long service life, low thermal expansion coefficient hiki ke hōʻoia i ka paʻa o ka ceramic heat sink i loko. ka ʻāina wela kiʻekiʻe a haʻahaʻa a i ʻole kahi ʻano ʻino ʻē aʻe;

Hiki i ka 5.Ceramic heat sink ke hana pono i ka anti-interference (EMI), anti-static;

6.Ceramic heat sink me ka hoʻohana ʻana i nā mea kūlohelohe kūlohelohe, e hoʻokō i nā koi o ka mālama ʻana i ke kaiapuni;

7.Ceramic heat sink's leo liʻiliʻi, māmā kaumaha, ikaika kiʻekiʻe, hiki ke mālama i ka lewa, mālama i nā mea, mālama i ka ukana, ʻoi aku ka maikaʻi o ka hoʻolālā kūpono o ka hoʻolālā huahana;

Hiki i ka 8.Ceramic heat sink ke kū i ke kiʻekiʻe o kēia manawa, ka uila kiʻekiʻe, hiki ke pale i ka leakage breakdown, ʻaʻohe walaʻau, ʻaʻole e hana i ka hoʻohui ʻana i ka capacitance parasitic me MOS a me nā paipu mana ʻē aʻe, a no laila e hoʻomaʻamaʻa i ke kaʻina kānana, pono ka mamao o ka creepage e pōkole ma mua o ka nā koi o ke kino metala, hiki ke ho'ōla hou i ka lumi papa, ʻoi aku ka maikaʻi o ka hoʻolālā ʻana o nā ʻenekinia a me ka hōʻoia uila.

Hoʻolauna Noi

Hoʻohana nui ʻia ka puʻu wela seramika i nā ʻāpana huahana e pono ai ka insulation conduction wela, e like me nā mea mana kiʻekiʻe, IC MOS tube, IGBT patch type heat conduction insulation, high-frequency power supply, communication, mechanical equipment.Eia kekahi, e hoʻohana pū ʻia ka radiator ceramic i ke kukui LED, ka welder kiʻekiʻe, ka mana amplifier / kani, ka transistor mana, ka mana module, chip IC, inverter, network / broadband, UPS power supply a pēlā aku.
