Kuthekani malunga nokusebenza kwe-skived fin heat sink?

Skived fin heat sinkluhlobo lwesitya sokutshisa esinamaphiko asikwe kwizinto eziqinileyo.Iifins kwi skived fin heat sink zibhityile xa kuthelekiswaezinye iintlobo zobushushu, njengayei-extrusion heat sinks.I-Skived fin heat sinks yenziwe yinkqubo yokuvelisa ebizwa ngokuba yi-skiving, eyenziwa ngumatshini wokutyibilika ochanekileyo kunye ne-blade ebukhali elawulwa ngokuchanekileyo, yasika iqhekeza elincinci lobunzima obuchaziweyo kwiprofayili yentsimbi yonke (AL6063 okanye i-C1100 yobhedu), emva koko igobe. iqhekeza elicekethekileyo lesinyithi ngokuthe nkqo ukwenza i-fins ye-sink fins.I-skived fin ye-heat sink ibonelela ngobuchule obuphezulu bokushisa kwizicelo eziphezulu zamandla.Olu hlobo lokutshisa ubushushu lubonelela ngezinto eziluncedo ezinjengokumelana nobushushu obuncinci, iindlela ezimfutshane zokuhambisa ubushushu, kunye nobukhulu obubambeneyo.Apha ngezantsi kukho inkcazo eneenkcukacha yokusebenza kwee-skived fin heat sinks ukusuka kwiimbono ezininzi.

1.Ukuxhathisa kweThermal: Ukumelana nobushushu kuchazwa njengomahluko weqondo lobushushu phakathi komthombo wobushushu kunye nemeko-bume yendawo engqongileyo, eyahlulwe bubushushu obuguquguqukayo, okanye isantya sokudluliselwa kobushushu, ngokutshona kobushushu:

I-Rth = (Umthombo - iTambient) / Q

apho i-Rth = ukumelana ne-thermal (ngama-degrees Celsius nge-Watt), i-Tsource = iqondo lokushisa lomthombo wokushisa, i-Tambient = iqondo lokushisa lendawo engqongileyo, kunye ne-Q = i-heat flux (kwi-Watts).

Skived fin heat sinks umbonisoukuchasana kwe-thermal ephantsi, engumlinganiselo wendlela ngokufanelekileyo isitya sokufudumeza esihambisa ubushushu ukusuka kumthombo ukuya kwindawo engqongileyo.I-skived fin heat sink inommandla omkhulu womphezulu ukuya kwi-volume ratioi-extrusion heat sinks, ezenza ukuba zisebenze ngakumbi ekukhupheni ubushushu.

2. Ukutshatyalaliswa kobushushu: Ngenxa yokuba ii-skived fins zineendonga ezinqabileyo ezifaniswa ne-extruded fins, ezibangela indawo enkulu yokushisa ukushisa.I-skived fins inommandla omkhulu woqhagamshelwano kunye nomthombo wobushushu, obangela ukubaukutshatyalaliswa kobushushu obuphezulu.Inkqubo yokutyibiliza ikwavumela ukuguquguquka okukhulu ekuyileni ijiyometri yofin, ivumela ukuhanjiswa kobushushu okusebenzayo ngakumbi.

3. Ubunzima kunye nobukhulu: I-skived fin heat sinks ziqhelekileyoilula kwaye incincikunezinye iintlobo zobushushu.Oku kuzenza zilungele ukusetyenziswa kwizixhobo zombane ezincinci ezinendawo encinci ekhoyo kwiinkqubo zokupholisa.

4. Ukuntsokotha kokwenziwa kwemveliso: Ukwenziwa kwe-skived fin heat sinkintsonkothe ​​ngakumbi kwaye ineendlekoxa kuthelekiswa nemveliso ye-extrusion heat sink.Ukuvelisa i-skived fin heat sinks kufuna izixhobo ezikhethekileyo kunye nabasebenzi abanezakhono.Ke i-skived fin heat sink iilungele ngakumbi ubungakanani odolo oluncinci.

5. Ukumelana nokuMhlwa: Izinki zobushushu ezenziwe nge-skived fin ezenziwe nge-aluminiyam okanye ubhedu zinokukhula xa zibekwe kwimichiza, ukufuma, okanye ezinye iimeko zokusingqongileyo., ngoko ke sihlala sidinga ukwenza unyango olungaphezulu kubo, i-skived fin heat sinksigqunywe ngomqolo wezinto ezikhuselayoukuthintela umhlwa.

Ngokubanzi, i-skived fin heat sink yenzelwe ukunciphisa ukuxhathisa kwe-thermal, kubangeleukutshatyalaliswa kobushushu okusebenzayokunye namaqondo obushushu asezantsi kwindawo yobushushu.Ukumelana ne-thermal ye-skived fin heat sink iphenjelelwa zizinto ezifana ne-fin geometry, iipropathi zezinto eziphathekayo, kunye nemeko yokusebenza skived fin heat sinks zaziwa ngokwazo.ukusebenza kakuhle kwe-thermal kunye nobukhulu obuncinci, ezenza zibe zilungele ukusetyenziswa kwizicelo zamandla aphezulu kunye nendawo encinci yeenkqubo zokupholisa.
