Yintoni umahluko phakathi kwe-skiving kunye ne-extrusion heat sink?

Iisinki zobushushu zisetyenziselwa ukuphelisa ubushushu obuvela kwizinto zombane ezifana nee-CPU, ii-LED, kunye nombane wamandla.Ukutyibiliza kunye ne-extrusion ziindlela ezimbini ezidumileyo zokwenza iisinki zobushushu.Nantsi iyantlukwano phakathi kweUkutyibiliza kwisitya sobushushukwayei-extrusion heat sinkubuchule:

1. 1.Inkqubo yokuvelisa

I-Extrusion yinkqubo yokunyanzela imathiriyeli ye-aluminiyam ngokufa ukuvelisa imilo efunekayo.Kubandakanya ukutyhala i-aluminiyam eshushu ngomngxuma omile kwidayisi.Inkqubo ivelisa i-heat sinks kunye ne-uniform cross-section kunye nobude obuhambelanayo.

Ukutyibiliza, kwelinye icala, yinkqubo yobuchwephesha ebandakanya ukusika ibhloko yealuminiyam ibe ngamaqhekeza amancinci ukwenza amaphiko.Uluhlu lokusikwa okuhambelanayo lwenziwa kwizinto eziphathekayo, kwaye iinqununu ezincinci zigobe kwi-angle efanelekileyo ukuze zenze i-fins.

1. 2.Ubungakanani kunye nobunzima

I-Extrusion ifaneleka ngakumbi ukuvelisa i-sinks enkulu kunye neyinkimbinkimbi yokushisa.Ekubeni iyinkqubo eqhubekayo, ingasetyenziselwa ukuvelisa iisinki zobushushu phantse nakuphi na ubude.I-Extrusion inokuvelisa i-heat sinks eneendawo ezinkulu ezinqamlezileyo.

I-Skiving, ngakolunye uhlangothi, ilungele ukuvelisa iisinki ezincinci zokushisa ezinomlinganiselo ophantsi (ubude ukuya kububanzi).Iisinki ezishushu ezishushu zidla ngokuba namaphiko amancinane kunezitsini zobushushu ezigqithisiweyo, kwaye zilungele ukusetyenziswa kwamandla aphantsi.

1. 3.Ubume kunye nesakhiwo

II-extrusion heat sinkiveliswa ngezinto ze-aluminiyam ezikhuphayo, ngoko ke isitya sobushushu sihlala sikwimilo eqhelekileyo efana nomgca othe ngqo okanye i-L-shape.I-Extrusion heat sink idla ngokuba nodonga olungqindilili, oluqinileyo noluhlala luhleli lulonke, kwaye inokumelana nemithwalo emikhulu yobushushu, iyenze ilungele izicelo zokuphelisa ubushushu bamandla aphezulu.Umphezulu we-Extrusion heat sink idla ngokuphathwa ngokukodwa ukunyusa indawo ephezulu kunye nokusebenza kakuhle kokutshatyalaliswa kobushushu.

IUkutyibiliza kwisitya sobushushuyenziwa ngokusika imathiriyeli yealuminiyam.Amaphiko e-Skiving ngokuqhelekileyo anesakhiwo esinodonga oluncinci olunamaphiko amancinci kwaye asebenzise inkqubo yokugoba ukwandisa indawo ephezulu.Ngenxa yolwakhiwo olukhethekileyo lwamaphiko, ii-Skiving fins ngokuqhelekileyo zinee-coefficients eziphezulu zokulahla ubushushu kunye nokumelana nomoya ophantsi.

1. 4.Ukusebenza kwe-Thermal

I-Skived heat sinksngokubanzi ukusebenza thermal ngaphezului-extruded heat sinksngenxa yokuba banamaphiko amancinci kunye nommandla ongaphezulu weyunithi nganye.Oku kubavumela ukuba bachithe ubushushu ngokufanelekileyo.Nangona kunjalo, kwezinye iimeko, ukuntsonkotha koyilo lobushushu obugqithisiweyo bunokwenza ukuncipha kokusebenza kwe-thermal.Xa ufuna i-fin density engafumanekiyo kusetyenziswa itekhnoloji ye-extrusion i-skived fin heat sink inokuba yeyona ndlela ilungileyo kwi-extruded heat sink.

1. 5.Iindleko

I-Extrusion ngokuqhelekileyo ixabisa ngaphantsi kune-skiving njengoko kuyinkqubo eqhubekayo efuna utshintsho oluncinci lwezixhobo.Nangona kunjalo, ukuyila kunye nokudala ukufa kokuqala kunokubiza kakhulu.

Ukutyibiliza, kwelinye icala, kubiza kakhulu ngenxa yesidingo semisebenzi yomatshini emininzi kunye nenqanaba eliphezulu lenkunkuma yezinto.

Isishwankathelo, I-extrusion ifaneleke kakhulu ekuveliseni i-sinks enkulu, eyinkimbinkimbi yokushisa, ngelixa i-skiving ifanelekile kwizinto ezincinci, eziphantsi kwamandla.Zombini iindlela zineenzuzo zazo kunye nokungonakali, kwaye ukhetho lokugqibela luxhomekeke kwiimfuno ezithile zesicelo.
