Saosaoa maualuga vs. Maualuluga-Malo le Millina mo Aluminum Heat Sinks

A'o fa'atupula'ia le mana'omia o le lalolagi mo vaifofo fa'amamafa maualuga, tagata gaosi oloafeagai ma le mamafa e optimizealumini su'ega vevelagaosiga.Fa'aliga saosaoa masani masani pulea le alamanuia, ae o lo'o tula'i mai faiga fa'atosina maualuga ua folafola mai e maua ai le gaosiga. O lenei suʻesuʻega e faʻatatauina fefaʻatauaʻiga i le va o nei metotia e faʻaaoga ai faʻamatalaga faʻaogaina o le lalolagi moni, faʻatalanoaina se va taua i suʻesuʻega faʻaogaina mo vaega faʻamalo eletise.

Metotia

1.Fuafuaga Fa'ata'ita'i

●Mea faigaluega:6061-T6 poloka alumini (150×100×25 mm)

●Meafaigaluega:6mm carbide pito vili (3-faili, ZrN-faʻapipiʻi)

● Pulea fesuiaiga:

HSM: 12,000–25,000 RPM, uta pu'e pea

HEM: 8,000–15,000 RPM fa'atasi ai ma fa'afeso'ota'i fesuia'i (50-80%)

2. Aoina o Fa'amaumauga

●Matala mata: Mitutoyo SJ-410 profilometer (5 fua/mea faigaluega)

● La'ei meafaigaluega: Keyence VHX-7000 microscope numera (lavalava ofu>0.3mm = toilalo)

● Fuafuaga o gaosiga: Suʻe taimi taʻavale ma Siemens 840D CNC ogalaau

I'uga & Iloiloga

1.Tulaga lelei

● Metotia: HSM HEM

● RPM sili ona lelei: 18,000 12,000

●Ra (μm):0.4 0.7

Fa'ai'uga maualuga a le HSM (itulau<0.05) fa'atasi ma fa'aitiitiga fa'atūina pito i luga i le saoasaoa maualuga.

2.Mea faigaluega Ola

● Ua le manuia meafaigaluega HSM i le 1,200 laina laina vs. HEM's 1,800 mita

● O la'ei fa'apipi'i na fa'atosinaina le faaletonu o le HSM, a'o le HEM na fa'aalia mamanu fa'a'asa

Talanoaga

1.Aafiaga Fa'atino

●Mo fa'aoga sa'o:E tumau pea le lelei o le HSM e ui i le maualuga o tau o meafaigaluega

●Fa'atosina maualuga:Ole taimi ole taamilosaga ole HEM e 15% e fa'amaonia ai le polesi pe a mae'a le masini

2. Tapulaa

● Le aofia ai 5-axis machining scenario

● Suʻega faʻatapulaʻa i meafaigaluega 6mm; lapopoa tetele e mafai ona suia ai taunuuga

Fa'ai'uga

O le HSM e tu'uina atu le fa'ai'uga maualuga i luga ole laiga mo su'ega vevela, ae sili atu le HEM ile gaosiga tele. O su'esu'ega i le lumana'i e tatau ona su'esu'e auala fa'afefiloi e tu'ufa'atasia ai pasi fa'ai'uga HSM ma le fa'a'au'au o le HEM.
