Qhov cuam tshuam ntawm qhov roughness ntawm aluminium kub dab dej

Qee cov dab dej kub hauv kev lag luam hauv lub dab dej kub yog tshwj xeeb tsim los ntawm aluminium alloy ua raw khoom thiab siv los ua cov khoom siv hluav taws xob. Lawv tsis tsuas yog tiv thaiv cov khoom sab hauv los ntawm kev khob thiab kev puas tsuaj tab sis kuj pab cov khoom siv hluav taws xob dissipate cua sov los ntawm kev ua cua sov.

 

Cov neeg uas tau tuaj rau hauv kev sib cuag nrog aluminium alloy cua sov dab dej feem ntau hnov ​​​​txog cov lus "aluminium alloy heat sink" thiab "heat sink aluminium profiles".

 

Yog vim li cas vim li cas peb thiaj li yuav tsum tau nruj me ntsis rau qhov roughness ntawm aluminium profile cua sov dab dej yog vim hais tias cov roughness muaj ntau ntau yam cuam tshuam rau lub dab dej kub.

 

Yuav ua li cas deg roughness cuam tshuam rau aluminium kub dab dej?

Hnav tsis kam, stability ntawm comatibility zog, fatigue zog, corrosion kuj.

 

 

 

Hauv qab no, peb yuav qhia rau koj qee qhov kev cuam tshuam tshwj xeeb ntawm roughness hauv cov ntsiab lus.

 

Qhov roughness ntawm qhov chaw cuam tshuam qhov hnav tsis kam ntawm qhov chaw. Qhov rougher ntawm qhov chaw, qhov me me ntawm qhov chaw sib cuag zoo ntawm qhov chaw mating, thiab qhov siab dua. Qhov no ua rau kom hnav sai dua.

 

 

Rau clearance haum, qhov rougher saum npoo yog, yooj yim dua nws yog hnav thiab clearance yuav maj mam nce thaum lub sij hawm ua hauj lwm. Rau kev cuam tshuam haum, micro peaks ntawm qhov chaw yog flattened thaum lub sij hawm sib dhos, txo qhov kev cuam tshuam tiag tiag thiab txo qhov sib koom ua ke.

 

 

Qhov saum npoo ntawm qhov chaw ntxhib muaj qhov tseem ceeb, xws li cov ntse ntse thiab cov kab nrib pleb, uas yog qhov nkag siab zoo rau kev ntxhov siab thiab yog li cuam tshuam rau lub zog qaug zog ntawm qhov chaw.

 

Qhov ntxhib saum npoo tso cai rau corrosive gases lossis kua dej nkag mus rau hauv txheej txheej ntawm cov hlau los ntawm cov kab noj hniav microscopic, ua rau nto corrosion.

 

 

Thaum tshav kub kub dab dej aluminium profile yog hais txog cov khoom siv raw khoom siv rau kev tsim cov dab dej kub, uas yog ib hom khoom siv raw uas yog melted los ntawm aluminium alloy manufacturers thiab tsim los ntawm lub siab casting yam tsis muaj kev ua lossis kev kho kom ntxaws. Nws yog cov khoom siv raw uas xav tau los ntawm cov chaw tsim khoom kub kub. Qhov saum npoo yog ntxhib thiab tsis muaj kev zoo nkauj. Lub tshav kub dissipation kev ua tau zoo tsis zoo, thiab nws tsis tuaj yeem phim cov khoom tshwj xeeb thaum lub sijhawm teeb tsa. Ntau tus neeg yuam kev ntseeg tias lub dab dej kub aluminium profile yog cov txheej txheem ua kom sov, uas ua rau kev dag ntxias thiab ntxiab.
