F: Cov nyhuv buffering zoo
Thaum cov txhuas ua npuas dej nce mus txog nws qhov taw tes tawm hauv qhov siab, cov npuas membrane deforms, tsis tu ncua deforming txheej los ntawm txheej, thiab cov npuas raug rhuav tshem, ua rau cov compression deformation zoo, yog li absorbing lub zog cuam tshuam thiab qhia cov nyhuv cushioning zoo.

G: Tsawg thermal conductivity ntawm txhuas ua npuas ncauj
Lub thermal conductivity ntawm txhuas ua npuas ncauj yog tsawg heev, tsuas yog 1/60 ~ 1/500 ntawm ntshiab txhuas, thiab cov coefficient ntawm linear expansion yog sib npaug rau cov ntshiab txhuas.
H: Aluminium ua npuas ncauj yog ib qho yooj yim rau txheej txheem
Aluminium ua npuas ncauj yog ib qho yooj yim rau kev ua txhua yam, xws li txiav, drilling, dabtsi yog khoov thiab embossing. Aluminium ua npuas ncauj tuaj yeem txiav rau hauv qhov sib txawv thiab qhov ntau thiab tsawg nrog lub saw. Aluminium ua npuas ncauj tuaj yeem yooj yim drilled thiab riveted, thiab aluminium npuas tuaj yeem khoov thiab embossed. Aluminium ua npuas ncauj kuj tuaj yeem ua tiav nrog tus neeg sawv cev sib txuas. Muab tshuaj txhuam rau kev sib txuas ntawm aluminium ua npuas ncauj.
I: Kev tsim kho yooj yim
Vim tias cov txhuas ua npuas ncauj yog lub teeb, nws tuaj yeem ntsia tau manually, thiab tshwj xeeb tshaj yog tsim rau cov chaw ua haujlwm siab xws li qab nthab, phab ntsa, thiab ru tsev.
