Thaum tshav kub kub exchanger phaj feem ntau yog ua los ntawm cov ntawv hlau los ntawm cov txheej txheem stamping, nrog ib tug corrugated nto ntawm ib tug tshwj xeeb zoo. Cov corrugations no ua rau cov kua dej turbulence, yog li kev txhim kho kev sib pauv cua sov. Lub qhov nyob ntawm plaub lub kaum sab xis ntawm daim phiaj rau kev tawm hauv thiab tawm. Cov phaj yog sib cais los ntawm gaskets, tsim cov dej ntws ywj pheej. Lub phaj thickness feem ntau yog nruab nrab ntawm 0.4 hli thiab 0.8 hli, nyob ntawm seb cov ntawv thov tshwj xeeb.
Kev xaiv ntawm cov khoom siv phaj yog nyob ntawm cov khoom ntawm qhov nruab nrab thiab kev ua haujlwm. Cov ntaub ntawv muaj xws li stainless hlau, titanium thiab titanium alloys, thiab npib tsib xee thiab npib tsib xee alloys. Stainless hlau daim hlau yog tsim rau feem ntau me me corrosive media thiab kuj pheej yig. Titanium thiab titanium alloy daim hlau muaj zog corrosion kuj thiab haum rau seawater los yog ib puag ncig nrog cov ntsiab lus chloride ion siab. Nickel thiab npib tsib xee alloy phaj yog tsim rau siab -kub los yog corrosive heev. Kev xaiv cov khoom siv yuav tsum ua tib zoo xav txog qhov chaw ua haujlwm thiab kev lag luam.
