Ubushushu butshonazidlala indima ebalulekileyo ekugcineni izixhobo ze-elektroniki zipholile.Njengoko iimfuno zezixhobo ze-elektroniki zisanda, ukusetyenziswa kwee-heat sinks kubaluleke ngakumbi.Kukho iindlela ezahlukeneyo zokwenza iitsinki zobushushu, kodwa ezona ndlela zimbini zixhaphakileyo ziintsinki zobushushu ezifayo kunye neesinki zobushushu ezikhutshiweyo.Makhe sijonge ngakumbi umahluko phakathi kwezi zipholileyo zimbini ukuze sifumanise ukuba yeyiphi engcono.
Yintoni i-die-cast heat sink?
I-Die-cast heat sinkyiheatsink eveliswa kusetyenziswa inkqubo yokuphosa ukufa.Inkqubo ibandakanya ukutofa isinyithi esinyibilikisiweyo kwisikhunta phantsi koxinzelelo oluphezulu.Intsimbi ke iphola ngokukhawuleza, yenze i-heat sink.Inkqubo yokuphosa i-die ingasetyenziselwa ukuvelisa iimilo ezintsonkothileyo kunye noyilo, iyenza ibe lukhetho oludumileyo lokwenziwa kweesinki zobushushu.
Yintoni i-extruded heat sink?
Isinki yobushushu eyongeziweyoyiheatsink eveliswa yinkqubo ye-extrusion.Kule nkqubo, intsimbi engenanto ityhalwa ngokufa ukuze yenze i-heat sink.I-Extrusion inokuvelisa iintlobo ezahlukeneyo zeemilo kunye nobukhulu, kodwa ayifanelekanga ukwenziwa koyilo olunzima.
Die Cast Heat sinks vs Extruded Heat sinks - Umahluko
1. Inkqubo yokuvelisa
Inkqubo yokuvelisa yenye yezona ntlukwano eziphawulekayo phakathifa ukuphosa i-sink yobushushukwayei-extrusion heat sink.Inkqubo yokuphosa i-die ibandakanya ukutofa isinyithi esityhidiweyo kwisingundo esiphantsi koxinzelelo oluphezulu, ngelixa inkqubo yokukhupha ibandakanya ukutyhala i-billet yesinyithi ngokufa.Inkqubo ye-die-casting inokuvelisa iimilo eziyinkimbinkimbi kunye noyilo, ngelixa inkqubo ye-extrusion ifaneleka ngakumbi kwiimilo ezilula.
2. Uyilo lokuguquguquka
Ububhetyebhetye boyilo ngomnye umahluko obalulekileyo phakathi kwe-die-cast kunye ne-extruded heat sinks.Ngenxa yokusetyenziswa kwesikhunta, i-die-cast heat sinks inokufikelela kwiimilo ezinzima kunye noyilo.Ngokwahlukileyo, i-extruded heat sinks ilinganiselwe kuyilo ngenxa yokusetyenziswa kwe-fixed cross-sectional shape for the heat sink.
3. Iindleko
Iindleko yenye into ebalulekileyo ekufuneka iqwalaselwe xa uthelekisa ukufa kunye neesinki zobushushu obugqithisiweyo.I-Die casting ibiza kakhulu kunenkqubo ye-extrusion ngenxa yeendleko zesixhobo kunye nokuchaneka okuphezulu okufunwa yinkqubo.Inkqubo ye-extrusion ayibizi kakhulu kwaye ingasetyenziselwa ukwenza iisinki zobushushu ngobuninzi.
4. Ukutshatyalaliswa kobushushu
Ukutshatyalaliswa kobushushu yinto ephambili ekufuneka iqwalaselwe xa ukhetha i-heat sink.Ngokuqhelekileyo i-die cast heat sinks ine-conductivity ephantsi ye-thermal kune-extruded heat sinks ngenxa yokusetyenziswa kwezinto .Umzekelo, i-extrusion heat sink ihlala isebenzisa i-AL6063 (ene-thermal conductivity ye-200W/mK) ngelixa i-die cast heat sinks ihlala isebenzisa i-ADC12 (kunye ne-thermal conductivity malunga nama-96W/mK).kodwa ukuze kuphuculwe i-thermal conductivity ye-die cast heat sink, sihlala sikhetha izinto ze-Aluminiyam ze-alloy ezilinganisa ubulukhuni kunye nokusebenza okungcono kokushisa ubushushu kune-ADC12.
IiSinki zoBubushushu beDie Cast vs iiSinki zoBubushushu obuOngeziweyo-Yeyiphi eNgcono?
Xa ukhetha phakathi kwe-die-cast kunye ne-extruded heat sinks, akukho mpendulo icacileyo malunga nokuba yeyiphi engcono.Ukhetho oluchanekileyo luxhomekeke kwizinto ezininzi, kubandakanywa uyilo lwe-heat sink, iindleko, kunye neemfuno zokusebenza kwe-thermal.Ngokubanzi, i-die-cast heat sink ifaneleka ngakumbi kwizicelo ezifuna iimilo ezinzima kunye noyilo.Ngakolunye uhlangothi, i-extruded heat sinks ifaneleka kangcono kwizicelo ezifuna iimilo ezilula kunye nokuveliswa kweendleko.
Cukuqukwa
Ukuqukumbela, ukhetho phakathi kweesinki zobushushu kunye neesinki ezigqithisiweyo zobushushu ziya kuxhomekeka kwiimfuno ezithile zesicelo.Indlela nganye ineengenelo kunye nokungona kwayo, kwaye ixhomekeke kwinjineli ukuba ithathe isigqibo sokuba yeyiphi indlela efanelekileyo ngakumbi kwisicelo.I-Die-cast heat sinks inikezela ukuguquguquka okukhulu koyilo, okubenza babe ukhetho olungcono kwizicelo ezinzima.I-extruded heat sinks, ngakolunye uhlangothi, ixabisa ngakumbi kwaye ifaneleka ngakumbi kwizicelo ezilula.Ngokuqwalasela zonke izinto ezichaphazelekayo, iinjineli zinokwenza isigqibo esinolwazi kwaye zikhethe isitya esifanelekileyo sokushisa kwisicelo sabo.
Iintlobo zeSinki yoBubushushu
Ukuze kuhlangatyezwane neemfuno ezahlukeneyo zokulahla ubushushu, umzi-mveliso wethu unokuvelisa iintlobo ezahlukeneyo zeesinki zobushushu ezinenkqubo ezininzi ezahlukeneyo, ezinje ngasezantsi:
