MICROCHIP AN4306 Malangizo Okwezera a Module Yopanda Mphamvu Yopanda Mphamvu

Mawu Oyamba

Cholemba ichi chimapereka malingaliro okweza moyenerera gawo lamagetsi lopanda maziko ku sinki ya kutentha ndi PCB. Tsatirani malangizo okwera kuti muchepetse kupsinjika kwa kutentha ndi makina.

Chiyanjanitso Pakati pa Baseless Power Module ndi Heat Sink

Gawoli likufotokoza mawonekedwe pakati pa module yamagetsi yopanda maziko ndi sink ya kutentha.

Phase Change Material (PCM) Kuyika

 

Kuti tikwaniritse otsika kwambiri kutentha lakuya matenthedwe kukana, ndi gawo kusintha chuma mafunsidwe mu zisa angagwiritsidwe ntchito pa zopanda maziko mphamvu gawo. Gwiritsani ntchito njira yosindikizira pazenera kuti muwonetsetse kuyika kofanana kwa makulidwe ochepera 150 μm mpaka 200 μm (5.9 mils mpaka 7.8 mils) pagawo lamphamvu lopanda maziko, monga momwe tawonetsera pachithunzichi. Microchip imalimbikitsa Loctite PSX-Pe. Kutentha kwamtunduwu kumachepetsa kupopera kunja. kutulutsa mpweya kumachitika chifukwa cha kutentha kwa njinga komwe kumachitika pakati pa malo awiri okwerera.

Zojambula za Aluminium zokhala ndi PCM

Kuti mukwaniritse zochepetsetsa zochepetsera kutentha kwa kutentha kwa kutentha, chojambula cha aluminiyamu chokhala ndi PCM kumbali zonse ziwiri (Kunze Crayotherm-KU-ALF5) chingagwiritsidwe ntchito pakati pa gawo la mphamvu zopanda maziko ndi kutentha kwa kutentha monga momwe tawonetsera mu chithunzi chotsatirachi.

Kuyika Module Yopanda Base ku Sink ya Kutentha

Kuyika moyenerera gawo lamagetsi lopanda maziko ku choyatsira kutentha ndikofunikira kuti zitsimikizire kutentha kwabwino. Kutentha kwamadzi ndi mphamvu zopanda maziko zolumikizirana ndi gawo lamphamvu ziyenera kukhala zosalala komanso zoyera (popanda dothi, palibe dzimbiri, komanso zosawonongeka) kuti mupewe kupsinjika kwamakina pamene gawo lamagetsi lopanda maziko limayikidwa ndikupewa kuwonjezeka kwa kukana kutentha.

Zindikirani: Kukhazikika kovomerezeka ndi <50 μm kwa 100 mm mosalekeza ndipo kulimbikira kovomerezeka ndi Rz 10. Ikani gawo la mphamvu zopanda maziko ndi PCM kapena zojambulazo za aluminiyamu ndi PCM pamwamba pa mabowo otenthetsa kutentha ndikugwiritsira ntchito kupanikizika kochepa kwa izo.

• Kwa BL1 ndi BL2 gawo lamphamvu lopanda maziko:
  • Ikani wononga M4 ndi makina ochapira masika (DIN 137A) mu dzenje lokwera. The screw mutu ndi washer awiri ayenera kukhala 8 mm mmene. Limbikitsani wononga mpaka mtengo womaliza wa torque uwu wafika. (Onani ndandanda yazogulitsa za torque yayikulu yololedwa).
• Kwa gawo lamphamvu la BL3 lopanda maziko:
  • Ikani zomangira za M3 ndi zotsukira masika (DIN 137A) mumabowo omangika. The screw mutu ndi washer awiri ayenera kukhala 6 mm mmene.

• Zomangira zisanu za M3 ziyenera kulumikizidwa mpaka 1/3 ya torque yomaliza. Order: 1 - 2 - 4 - 3 - 5.
• Zomangira zisanu za M3 ziyenera kulumikizidwa mpaka 2/3 ya torque yomaliza. Order: 1 - 5 - 3 - 4 - 2.
• Zomangira zisanu za M3 ziyenera kulumikizidwa ku torque yomaliza. Order: 3 - 5 - 4 - 2 - 1.

Onani tsatanetsatane wazinthu zomwe zimaloledwa. Kuti muchite izi pama module onse opanda mphamvu, gwiritsani ntchito screwdriver yokhala ndi torque yoyendetsedwa.

PCB Assembly pa Baseless Power Module

Zotsatirazi ndi njira zosonkhanitsira PCB pagawo lamphamvu lopanda maziko.

1. Ikani ma spacers pamadzi otentha pafupi ndi gawo la mphamvu zopanda maziko. Ma spacers ayenera kukhala 10±0.1 mm wamtali.
   • Zindikirani: Module yopanda maziko ndi 9.3 mm wamtali. Ma spacers ayenera kukhala pafupi ndi ma module opanda maziko kuti apewe kugwedezeka kulikonse ndikulemekeza zofunikira zotchinjiriza, monga zikuwonekera pachithunzichi. PCB iyenera kukwera ku gawo lamagetsi lopanda maziko ndikumangirira ma spacers. Ma torque okwera a 0.6 Nm (5 lbf·in) akulimbikitsidwa.
2. Solder zikhomo zonse zamagetsi za gawo la mphamvu ku PCB. Palibe kutulutsa koyera kwa solder komwe kumafunikira kuti muphatikize PCB pagawo popeza kuyeretsa kwamadzi sikuloledwa.

Zindikirani: Osasintha masitepe awiriwa, chifukwa ngati zikhomo zonse zimagulitsidwa koyamba ku PCB, kugwetsa PCB pa spacers kumapangitsa kuti PCB iwonongeke, zomwe zimatsogolera kupsinjika kwamakina komwe kungathe kuwononga njanji kapena kuswa zigawo za PCB.

Kuti apange bwino, njira yowotchera mafunde ingagwiritsidwe ntchito kugulitsa ma terminals ku PCB. Ntchito iliyonse, kutentha kwakuya ndi PCB kungakhale kosiyana; ma wave soldering amayenera kuyesedwa pafupipafupi. Mulimonsemo, wosanjikiza bwino wa solder ayenera kuzungulira pini iliyonse.

Mabowo mu PCB (onani Chithunzi 4-1) ndi ofunikira kuchotsa zomangira zomangira zomwe zimatsekereza gawo lamagetsi lopanda maziko ku sinki ya kutentha. Mabowo olowera awa ayenera kukhala akulu kuti wononga mutu ndi ma washer kudutsa momasuka, kulola kulolerana kwabwinobwino pamalo a dzenje la PCB.

Kusiyana pakati pa pansi pa PCB ndi gawo la mphamvu zopanda maziko ndilotsika kwambiri. Microchip sichimalangiza kugwiritsa ntchito zigawo za dzenje pamwamba pa gawo. Kuchepetsa kusintha kwa voltages, SMD decoupling capacitors wa ma terminals VBUS ndi 0/VBUS angagwiritsidwe ntchito. (Onani Chithunzi 4-1). Onetsetsani chitetezo mukamanyamula zinthu zolemetsa monga ma electrolytic kapena polypropylene capacitors, ma transfoma, kapena ma inductors oyikidwa mozungulira gawo lamagetsi. Ngati zigawozi zili m'dera lomwelo, yonjezerani ma spacers kuti kulemera kwa zigawozi pa bolodi zisasamalidwe ndi module yopanda mphamvu koma ndi spacers. Pin kunja ikhoza kusintha malinga ndi kasinthidwe. Onani tsatanetsatane wazinthu zomwe zatsitsidwa. Kugwiritsa ntchito kulikonse, PCM, PCB, ndi ma spacers kuyika ndi kosiyana ndipo kuyenera kuwunikidwa pakamodzi ndi mlandu.

BL1, BL2, ndi BL3 Assembly pa PCB yomweyo

1. Kufotokozera kwa msonkhano kumapangidwa ndi ma modules atatu opanda mphamvu: Ma module awiri a BL1 opanda maziko a mlatho wokonzanso, BL2 imodzi, ndi gawo limodzi la BL3 lopanda maziko lamagetsi a mlatho wa magawo atatu.

• Assembly kwa wapawiri AC lophimba pa BL3 mphamvu gawo kuchita masanjidwewo kukhudzana kwa ndege mphamvu mphamvu (mpaka 50 kW).

Mapeto

Cholemba ichi chimapereka malingaliro okhudza kuyika kwa module yopanda maziko. Kugwiritsa ntchito malangizowa kumathandizira kuchepetsa kupsinjika kwamakina pa PCB ndi gawo lamagetsi lopanda maziko kuti zitsimikizire kugwira ntchito kwa nthawi yayitali. Malangizo okwera ku sinki ya kutentha ayeneranso kutsatiridwa kuti akwaniritse kukana kwamafuta otsika kwambiri kuchokera ku tchipisi tamagetsi kupita ku chozizira. Ntchito zonsezi ndizofunikira kuti zitsimikizire kudalirika kwadongosolo.
