Nanga bwanji skived fin heat sink performance?

Sinki yotentha yotenthandi mtundu wa sink ya kutentha yokhala ndi zipsepse zomwe zimadulidwa kuchokera ku zinthu zolimba.Zipsepse mu sink yotenthetsera ya skived fin ndizochepa kwambiri poyerekeza ndimitundu ina ya kutentha kwakuya, mongakutentha kwa extrusion.Masinthidwe otentha a skived fin amapangidwa ndi njira yopanga yotchedwa skiving, yomwe imapangidwa ndi makina apamwamba kwambiri otsetsereka okhala ndi tsamba lakuthwa loyang'aniridwa bwino, amadula chidutswa chochepa kwambiri cha makulidwe odziwika kuchokera pachigawo chonse chachitsulo (AL6063 kapena mkuwa C1100), ndiye pindani. Chigawo chopyapyala chachitsulo chowongoka kuti chipange zipsepse zomangira kutentha. The skived fin heat sink imapereka mphamvu zotentha kwambiri pakugwiritsa ntchito mphamvu zambiri.Kutentha kwamtunduwu kumapereka maubwino monga kukana kutentha pang'ono, njira zazifupi zosinthira kutentha, ndi kukula kophatikizana.Pansipa pali mafotokozedwe atsatanetsatane a magwiridwe antchito a skived fin heat sinks kuchokera kumawonedwe angapo.

Kukaniza kwa 1. Thermal Resistance: Kukaniza kwa kutentha kumatanthauzidwa ngati kusiyana kwa kutentha pakati pa gwero la kutentha ndi malo ozungulira, ogawanika ndi kutentha kwa kutentha, kapena kutentha kwa kutentha, kupyolera mumtsinje wa kutentha:

Rth = (Tsource - Tambient) / Q

kumene Rth = kukana kwa kutentha (mu madigiri Celsius pa Watt), Tsource = kutentha kwa gwero la kutentha, Tambient = kutentha kwa chilengedwe chozungulira, ndi Q = kutentha kwa kutentha (mu Watts).

Chiwonetsero cha skived fin heat sinkkuchepetsa kukana kwamafuta, womwe ndi muyeso wa momwe choyimira chotenthetsera chimasamutsa kutentha kuchokera kugwero kupita kumalo ozungulira.Sinki yotentha ya skived fin imakhala ndi malo okulirapo kuposa kuchuluka kwa voliyumu kuposakutentha kwa extrusion, zomwe zimawapangitsa kuti azigwira bwino ntchito pochotsa kutentha.

2. Kutentha kwa kutentha: Chifukwa zipsepse za skived zimakhala ndi makoma owonda kwambiri poyerekeza ndi zipsepse zotuluka, zomwe zimapangitsa kuti pakhale malo akuluakulu opangira kutentha.Zipsepsezo zimakhala ndi malo akuluakulu okhudzana ndi kutentha, zomwe zimabweretsakutentha kwapamwamba kwambiri.Njira yotsetsereka imalolanso kusinthasintha kwakukulu pakupanga fin geometry, kupangitsa kusamutsa kutentha kwachangu.

3. Kulemera ndi Kukula kwake: Masinthidwe otentha a skived fin amakhala nthawi zambirizopepuka ndi zazing'onokuposa mitundu ina ya kutentha kwakuya.Izi zimawapangitsa kukhala abwino kuti azigwiritsidwa ntchito pazida zing'onozing'ono zamagetsi zomwe zili ndi malo ochepa omwe amapezeka kuti azizizira.

4. Kupanga zovuta: Skived fin heat sink kupanga ndizovuta komanso zodulapoyerekeza ndi kupanga extrusion kutentha kumira.Kupanga masinki otentha a skived fin kumafuna zida zapadera komanso anthu aluso.Ndiye skived fin heat sink ndiabwino kwambiri kwa kuchuluka kwa dongosolo laling'ono.

5. Kusawonongeka kwa dzimbiri: Masinthidwe otentha a zipsepse opangidwa kuchokera ku aluminiyamu kapena mkuwa amatha kuchita dzimbiri akakumana ndi mankhwala, chinyezi, kapena zinthu zina zachilengedwe., kotero nthawi zambiri timafunika kuwachitira mankhwala apamwamba, masinki otentha amatenthedwayokutidwa ndi wosanjikiza wa zinthu zotetezakupewa dzimbiri.

Ponseponse, skived fin heat sink idapangidwa kuti ichepetse kukana kwamafuta, zomwe zimapangitsakutentha kwachangundi kutentha kwapansi pa gwero la kutentha.Kukanika kwa kutentha kwa sink yotenthetsera ya skived fin kumatengera zinthu monga fin geometry, katundu wakuthupi, ndi momwe amagwirira ntchito skived fin heat sink amadziwika chifukwa chake.mkulu matenthedwe dzuwa ndi yaying'ono kukula, kuwapanga kukhala abwino kuti agwiritsidwe ntchito pamagetsi apamwamba okhala ndi malo ochepa a machitidwe ozizira.
