Isinki yobushushu

I-heat sink sisixhobo se-thermodynamic esisusa ubushushu kwiinkqubo zoomatshini, zombane kunye nezombane.Kwizixhobo ezahlukeneyo kunye noomatshini, kubalulekile ukugcina uluhlu lobushushu ngaphakathi komda othile ukugcina ukusebenza kweso sixhobo okanye umatshini.Apha indima ye-heater-sinks idlala.Umzekelo, oomatshini abakhulu belaptop yakho kumashishini ahlukeneyo kufuneka bachithe ubushushu bawo.Ngoko khawucinge indlela esetyenziswa ngokubanzi ngayo kwihlabathi lanamhlanje lobugcisa.I-Heat sinks ichitha ubushushu ngokuyidlulisela kwindawo elawulwayo, efana nomoya okanye ulwelo, emva koko ikhutshwe kwi-apparatus kunye ne-transfer medium.

Eli nqaku liza kuhamba ngokufutshane kwiukusebenza kwe-heat sink, amanyathelo oyilo, kunye neendlela zokuvelisa.

Ukusebenza kweSinki yoBubushushu

Umthetho weFourier wokudluliselwa kobushushu, othi ubushushu buhlala buhamba ukusuka kwiqondo eliphezulu ukuya kwindawo yobushushu obuphantsi, unika isiseko sendlela yokusebenza kwe-heat sink.Ngelixa izixhobo zivelisa ubushushu, obushushu kunomoya okanye ulwelo olujikelezileyo, zibudlulisa obo bushushu ngokuhambisa, nge-convection, okanye ngamanye amaxesha ngemitha kunxibelelwano olupholileyo.

Makhe sijonge kwi-flow-chart engezantsi ngomfanekiso ocacileyo wokusebenza kwe-heat-sink;

Itshati equkuqelayo yokusebenza kwesinki yobushushu

·   Ubushushu obungatshintshiyo butshona

Iizinki zobushushu obungatshintshiyo ngokwendalo zidlulisela ubushushu obufunnyiweyo kumoya ojikeleze ngaphandle kokuhanjiswa ngamandla, okufana nefeni okanye ukujikeleza kwamanzi okuwangqongileyo.Ezi zikholisa ukuba zikhulu ngokwemilo kwaye ziqulathe uluhlu olupheleleyo oluvezwe kwindawo engaphandle.

·   Isinki yobushushu esebenzayo

Isinki sobushushu esisebenzayo siquka ifeni eyongezelelweyo okanye isivuthelo kunye nolwelo olusekiweyo ukususa ubushushu ngaphandle kwendlela yendalo.Olu cwangciso olongezelelweyo lwandisa inkqubo yokutshatyalaliswa kobushushu ngenkqubo yokuhambisa ngenkani.Umzekelo, xa ifeni isebenza, yongeza isantya somoya kwaye ngokukhawuleza igqithise ubushushu ukusuka kwindawo yokutshisa ubushushu ukuya kwindawo engqongileyo.

Ukubalwa kokumelana ne-thermal

Ngexesha lokuYilwa kwesitya sobushushu, ukubalwa kokumelana ne-thermal iyonke (R_hs) idlala indima ebalulekileyo ekuqondeni ukusebenza okunokwenzeka kunye nokusebenza kakuhle, ngoko makhe sibone ukuba ingabalwa njani;

R_hs= (T_j-T_a/P) – (R_th-jc) -R_I

P= Ubushushu obuchithiweyo bubonke

T_I= Ubukhulu bobushushu besiphambuka sesixhobo kwi-0C.

R_th-jc= Ukuhlangana kwimeko yokumelana ne-thermal

T_a= Ubushushu bomoya kwi⁰C.

R_I= Ukuchaswa kwemathiriyeli yojongano

R_I= (t/L x W x K_I)

t = ubukhulu besixhobo sojongano

K_I=I-Thermal conductivity ye-interface yezinto

L = Ubude bomthombo wobushushu

W =Ububanzi bomthombo wobushushu

Uyilo lweSinki yoBubushushu

Kukho amanyathelo amaninzi ekuyileni.Makhe sijonge nganye kuzo ngokufutshane.
