1. Dab tsi yog qhov tseem ceeb ntawm cov nyias muaj tubing hauv cov ntawv thov tsheb?
Teb:
Aluminium tubing yog dav tau muaj kev xav tau hauv cov tshuab tsheb vim tias:
Luj txo kev txo: {50-60 ncu dua li cov hlau, txhim kho roj efficiency (EPA kwv yees 1%% MPG nce rau 100 lbs cawm).
Corrosion Kuj: Withstands txoj kev salts thiab tshuaj lom neeg, txuas ntxiv ntxias li cas los 15 xyoos.
Thermal conductivity: Tsim nyog rau cov kev sib pauv cua sov (piv txwv li, radiators) nrog 235 w \/ mith thermal hloov efficiency.
Tus yam ntxwv: Tesla lub roj teeb txias tshuab siv {{0} T6 Aluminium Hlab Rau Kev Tswj Hluav Taws Xob.
2. Yuav ua li cas ua lub tubing tubing txhim kho Aerospace roj tshuab?
Teb:
Aerospace cov ntawv thov qevis rog tubing rau:
Siab zog-rau-qhov hnyav piv: {{2024- t3 alloy withstands 470 MPa kev ntxhov siab ntawm 40% phaus txuag hluav taws xob vs. titanium.
Qeeb zog tsis kam: Seamless Tubes Txo kev pheej hmoo nyob rau hauv kev co (FAA deb 25.981 ua raws li).
Dabtsi Yog Khoov Dabtsi Yog Khoov: CNC Mandrel Dabtsi Yog Khoov Tso Rau Hauv Kev Coj Hauv Tebchaws Airframe Constraints.
Kev Kawm Txog: Boeing 787 siv Aluminium roj kab nrog PTFE liner kom tiv thaiv microbial kev loj hlob.
3. Dab tsi cov kev kho kom zoo ua kom cov tub rog ib puag ncig?
Teb:
Kev kho mob tseem ceeb xws li:
Anodizing (ntaus III): {50-100}} μm nyuaj rhiab tiv taus ntsev pitting (Astm B580 tus qauv).
Lub Chromate Conversion: Tsim tus kheej kho oxide txheej rau kev kos tsis kam.
Epoxy txheej: Dual txheej txheej txheej tiv thaiv cov ntu submerged (piv txwv li, thauj pob tawb tshuab.
Pro taub: Alloy {5052- h32 yog qhov nyiam rau nws cov marine-qib corrosion tsis kam.
4. Yuav ua li cas txhuas txoj hlab nqaij cuam tshuam h0ac system ua haujlwm?
Teb:
Kev xaiv tsim tsim:
Phab Ntsa Thickness: {{0. {{{{Mi mi mi mi mi mi mi mi mi mi mi moon cuam tshuam siab (ansi \/ ashrae 15) nrog kev hloov cua sov.
Qhov dav: {6-25 mm tubes off optimize txias ({{} m \/ s kom tsis txhob muaj cov roj ntaiv).
Seamless vs. Welded: Seamless hlab (Astm B210) tiv thaiv kom tsis txhob muaj dej siab R410A.
Ib leeg: HVAC cov tshuab nrog cov hlab nyias muaj zog qhia 12% tus neeg pom ntau dua cov lus piv txwv.
5. Dab tsi ua cov txheej txheem ua dua tshiab siv rau kev lag luam tub ntxaij cov khib nyiab?
Teb:
Kaw-lub voj rov ua npe koom nrog:
Cais: Eddy tam sim no Separators tshem cov tsis yog cov paug tsis huv (98% Purity tiav).
Ntxiv cov: Seem melted ntawm 660 degree (Zog siv: 5% ntawm cov thawj khoom lag luam).
Rov ua: Siv Bricets rov ua dua tshiab rau hauv cov hlab tshiab (piv txwv li, cov kab hluav taws hydro 75r alloy).
