Uyini umehluko phakathi kwe-skiving ne-extrusion heat sink?

Osinki bokushisa basetshenziselwa ukuqeda ukushisa okuvela ezingxenyeni ze-elekthronikhi ezifana nama-CPU, ama-LED, namandla kagesi.I-skiving ne-extrusion izindlela ezimbili ezidumile zokukhiqiza amasinki okushisa.Nansi umehluko phakathi kweskiving ukushisa usinkifuthii-extrusion heat sinkamasu:

1. 1.Inqubo yokukhiqiza

I-Extrusion iyinqubo yokuphoqelela impahla ye-aluminium ngokusebenzisa idayisi ukuze kukhiqizwe umumo oyifunayo.Kubandakanya ukusunduza i-aluminiyamu eshisiwe ngembobo emise okwedayi.Inqubo ikhiqiza amasinki okushisa ane-cross-section efanayo nobude obungaguquki.

Ngakolunye uhlangothi, ukushushuluza kuwumsebenzi womshini ohlanganisa ukusika ibhulokhi le-aluminium libe izingcezu ezincane ukuze kwakhiwe amaphiko.Uchungechunge lokusikeka okuhambisanayo lwenziwa kube impahla, futhi izingcezu ezincane zibe sezigotshwa zibe i-engeli efanele ukuze zakhe amaphiko.

1. 2.Ubukhulu nobunkimbinkimbi

I-Extrusion ifaneleka kangcono ukukhiqiza amasinki amakhulu futhi ayinkimbinkimbi.Njengoba kuyinqubo eqhubekayo, ingasetshenziswa ukukhiqiza amasinki okushisa cishe anobuphi ubude.I-Extrusion ingaphinda ikhiqize amasinki okushisa anezindawo ezinkulu eziphambanayo.

Ukushushuluza, ngakolunye uhlangothi, kulungele ukukhiqiza amasinki amancane okushisa ane-aspect ratio ephansi (isilinganiso sobude ukuya kobubanzi).Osinki bokushisa abashushuluziwe ngokuvamile banama-fins azacile kunamasinki okushisa angaphezulu, futhi ngokuvamile bafaneleka kakhulu izinhlelo zokusebenza zamandla aphansi.

1. 3.Isimo nesakhiwo

II-extrusion heatsinkikhiqizwa ngezinto ze-aluminium eziphumayo, ngakho-ke usinki wokushisa uvame ukuba nezimo ezijwayelekile njengomugqa oqondile noma umumo ka-L.Isinki sokushisa se-Extrusion ngokuvamile sinodonga oluwugqinsi oluqinile, oluqinile futhi oluhlala isikhathi eside, futhi lungakwazi ukumelana nomthwalo omkhulu wokushisa, okulwenza lufanelekele izinhlelo zokusebenza zokulahla ukushisa kwamandla aphezulu.Ingaphezulu likasinki wokushisa we-Extrusion ngokuvamile liphathwa ngokukhethekile ukuze kwandiswe indawo engaphezulu kanye nokusebenza kahle kokukhipha ukushisa.

II-Skiving heat sinkikhiqizwa ngokusika impahla ye-aluminium.Amaphiko e-skiving ngokuvamile anesakhiwo esinodonga oluncane olunamaphiko amancane futhi asebenzisa inqubo yokugoba ukukhulisa indawo engaphezulu.Ngenxa yesakhiwo esiyingqayizivele sama-fins, amaphiko e-Skiving ngokuvamile anama-coefficients aphezulu okuqeda ukushisa kanye nokumelana komoya okuphansi.

1. 4.Ukusebenza okushisayo

Amasinki okushisa agwetshiwengokuvamile abe nokusebenza okushisayo okuphezulu kunoamasinki okushisa akhishiwengoba zinamaphiko amancanyana kanye nendawo engaphezulu yevolumu ngayinye.Lokhu kuzivumela ukuthi zikhiphe ukushisa ngokuphumelelayo.Kodwa-ke, kwezinye izimo, inkimbinkimbi yedizayini yesinki yokushisa ekhishiwe ingakha ukusebenza okuncishisiwe kokushisa.Uma udinga i-fin density engakwazi ukutholwa kusetshenziswa ubuchwepheshe be-extrusion isinki yokushisa ye-skived fin ingaba enye indlela ehlukile kunesinki wokushisa okhishiwe.

1. 5.Izindleko

I-Extrusion ngokuvamile ibiza kancane kunokushushuluza njengoba kuyinqubo eqhubekayo edinga izinguquko ezimbalwa zamathuluzi.Kodwa-ke, ukuklama nokudala ukufa kokuqala kungabiza.

Ngakolunye uhlangothi, ukushushuluza kubiza kakhulu ngenxa yesidingo semisebenzi eminingi yemishini kanye nezinga eliphakeme lokulahlwa kwezinto ezibonakalayo.

Ngokufigqiwe, i-extrusion ifaneleka kakhulu ukukhiqiza amasinki amakhulu, ayinkimbinkimbi okushisa, kuyilapho ukushushuluza kulungele izinhlelo zokusebenza ezincane, zamandla aphansi.Zombili izindlela zinezinzuzo nezinkinga zazo, futhi ukukhetha kokugcina kuncike ezidingweni ezithile zohlelo lokusebenza.
