uila no ka hana

Maikaʻi thermal conductivity, he uumi kaʻi lau waiwai o thermal? Aiey a me ka poʻokela mea maemae. Kālaʻe nani: Our nā huahana no na uila no ka hana i loa kūikawā physical waiwai. Hoʻohana 'ia i kumu papa, a me ka wela spreaders, ka mea hoʻopaʻa i ka pono o ka uila lako a pan.

Ma mua kilohi, ka mea e pou eiiiiiaiou paha wela makemake ole e huhūʻoukou iā ia i kekahi mea e hopohopo ai. Kēia manawa, kokoke kekahi schoolchild ke hai aku ia oukou i ka māhele o ka kamepiula e pumehana ana ka mea ua ua hō'ā ia. Oiai ka mea ua hoʻohana, he nui o ka lako uila ikehu ua lilo i ka wela. Akā, e mākou lawe i kokoke nana: ka hoolilo o ka wela hiki ke olelo ia no hoi me ka wela koko no pa alima (o) wahi (wela koko nuʻa). E like me ka examples i loko o ka pakuhi kahaki, o ka wela koko paʻapū i nā lolouila eiiiiiaiou hiki e loa. Like kiʻekiʻe like i loko o ka rocket kīʻamo kania-i a me ka mahana like kiʻekiʻe me 2 800 ° C e ala mai oe.

Ke kaʻi lau waiwai o thermal? Anoe? Aiey i kekahi pilikia ololi no a pau semiconductors. Inā ka mea uholo uila, a me ka waihona ipu papa i nā puke? Anoe a me ka palapala ma kekahi mau kumu wā paku ole ia i loli ma ka wela laila me mechanical aʻo nui e ala mai oe. O ke hanaʻino i ka mea uholo uila a hihia hoʻi i loko o ka pilina ma waena o ke? Inoaia, a me ka wela spreader. Eia naʻe, a me kā mākou mau mea, e ike no oe i ka palekana lima. Mākou mau mea i ka kaʻoi loa kaʻi lau waiwai o thermal? Anoe? No ka hui ana semiconductors a me ka pālolo.

Uila no-hana

E like me ka mea uholo uila kumu papa, no ka laʻana, ua hoʻohana 'ia mākou i nā mea i loko o ka makani turbines, Loko a me ka hanalima noi. Ma ka mana mea uholo uila modules no inverters (thyristors) a me ka mana diodes, paani ae la lakou i kekahi kūlana pilikia. No ke aha mai? Mahalo i ko kaʻoi loa kaʻi lau waiwai o thermal? Aiey a me ka maikaʻi thermal conductivity, mea uholo uila kumu papa hana i ke kumu ikaika i ka 'ikepili koʻikoʻi silikone mea uholo uila, a hōʻoia i ka Module hana ola o ka luna o 30 makahiki.

Heat spreaders a me ka hoʻokumu 'ia nā papa i mai molybdenum, tungsten, MoCu, WCu, cu-MoCu a cu-MoCu-cu laminates reliably dissipate i ka wela ua loaʻa i loko o pou eiiiiiaiou. Kēia nā 'ano ua ālai ka overheating o ka pou manaʻo, a maoli he huahana wa e ola ana. Mākou wela spreaders kōkua malama i kekahi me nā papa hana, no ka laʻana, ma ka IGBT modules, RF pūʻolo helu a alakaʻi inoaia. Ua ulu mākou i ka loa kūikawā MoCu ahupapa mea no ka lawe papa i alakaʻi inoaia. Kēia i He kaʻi lau waiwai o thermal? Aiey like i ka mea o ka aiai a me ka pālolo.

E hoolako mākou nā huahana no na uila no hana me kaʻano o ka paleʻana. Ka mea, e ku e ka popopo hoomalu aku i na mea a me ka hoʻoikaika 'ana i ka solder pili ma waena o ka mea uholo uila a me kā mākou mea.
