Yuav ua li cas rau skived fin heat sink kev ua tau zoo?

Skived fin kub dab dejyog hom dab dej kub nrog cov fins uas raug txiav tawm ntawm cov khoom siv.Cov fins nyob rau hauv lub skived fin heat sink yog thinner piv raulwm hom cua sov dab dej, zoo liextrusion cua sov dab dej.Skived fin heat sinks yog tsim los ntawm cov txheej txheem tsim khoom hu ua skiving, uas yog tsim los ntawm high precision skiving tshuab nrog raug tswj ntse hniav, nws txiav nyias daim nyias thickness los ntawm tag nrho cov hlau profile (AL6063 los yog tooj liab C1100), ces khoov lub nyias daim hlau vertically tsim lub dab dej kub fins.The skived fin heat sink muab siab thermal efficiency nyob rau hauv high-power daim ntaub ntawv.Hom dab dej kub no muaj qhov zoo xws li thermal kuj tsawg, luv dua tshav kub hloov mus, thiab compact loj.Hauv qab no yog cov lus piav qhia ntxaws ntxaws ntawm kev ua haujlwm ntawm skived fin heat sinks los ntawm ntau qhov kev xav.

1.Thermal Resistance: Thermal resistance yog txhais raws li qhov sib txawv ntawm qhov kub ntawm qhov kub thiab qhov chaw ib puag ncig, muab faib los ntawm cov cua kub flux, los yog tus nqi ntawm cov cua kub hloov mus rau hauv lub dab dej kub:

Rth = (Tsource - Tambient) / Q

qhov twg Rth = thermal resistance (in degrees Celsius per Watt), Tsource = kub ntawm lub tshav kub, Tambient = kub ntawm ib puag ncig, thiab Q = kub flux (hauv Watts).

Skived fin heat sinks nthuav tawmqis thermal kuj, uas yog ib qho kev ntsuas ntawm qhov ua tau zoo ntawm lub dab dej kub hloov cov cua sov los ntawm qhov chaw mus rau ib puag ncig ib puag ncig.Lub skived fin heat sink muaj thaj tsam loj dua rau qhov ntim piv duaextrusion cua sov dab dej, uas ua rau lawv zoo dua ntawm dissipating tshav kub.

2. Thaum tshav kub kub Dissipation: Vim hais tias skived fins muaj cov phab ntsa thinner piv rau extruded fins, ua rau thaj tsam loj dua rau kev hloov mus rau cov cua sov.skiving fin heat sinks muaj thaj tsam loj dua piv rau extrusion heat sinks, lawv muaj peev xwm dissipate ntau cua sov.Cov skived fins muaj qhov chaw sib cuag loj dua nrog cov cua sov, uas ua rausuperior tshav kub dissipation.Cov txheej txheem skiving tseem tso cai rau kev hloov pauv ntau dua hauv kev tsim cov fin geometry, ua kom muaj txiaj ntsig zoo dua cov cua sov.

3. Qhov hnyav thiab qhov loj: Skived fin heat sinks feem ntausib dua thiab me duadua li lwm hom cua sov dab dej.Qhov no ua rau lawv zoo tagnrho rau siv hauv cov khoom siv hluav taws xob me me uas muaj qhov txwv tsis pub muaj rau cov tshuab cua txias.

4. Manufacturing complexity: Skived fin heat sink manufacturing yogntau complex thiab kimpiv rau extrusion heat sink manufacturing.Kev tsim cov skived fin heat sinks yuav tsum muaj cov cuab yeej tshwj xeeb thiab cov neeg ua haujlwm txawj.Yog li skived fin heat sink yoghaum rau me me kom muaj nuj nqis.

5. Corrosion Resistance: Skived fin heat sinks ua los ntawm txhuas los yog tooj liab yuav corrode thaum raug tshuaj lom neeg, av noo, los yog lwm yam ib puag ncig., yog li peb feem ntau xav tau kev kho deg rau lawv, skived fin heat sinks yogcoated nrog ib txheej ntawm cov khoom tiv thaivtiv thaiv corrosion.

Zuag qhia tag nrho, skived fin kub dab dej yog tsim los txo cov thermal tsis kam, ua rauua kom sov dissipationthiab txo qhov kub ntawm qhov cua sov.Lub thermal tsis kam ntawm skived fin cua sov dab dej yog cuam tshuam los ntawm cov yam ntxwv xws li fin geometry, cov khoom siv, thiab kev ua haujlwm ntawm skived fin heat sinks paub txog lawv.high thermal efficiency thiab compact loj, ua rau lawv zoo tagnrho rau siv nyob rau hauv high-power daim ntaub ntawv nrog txwv qhov chaw rau cua txias systems.
