Ndeipi simbi inobvisa kupisa nekukurumidza?

Foam yemhangura inozivikanwa nekunaka kwayo yekupisa conductivity. Mhangura ine thermal conductivity inosvika 398 W/m·K, zvichiita kuti ive imwe yeakanakisa kupisa maconductor emasimbi ese. Izvi zvinoitafuro remhangurayakanakira maapplication anoda kukurumidza kupisa kupisa, senge kupisa exchangers, emagetsi kutonhora masisitimu uye thermal manejimendi mhinduro. Iyo yakanyanya porous chimiro chemhangura foam inopawo hombe yekupisa kupisa pamusoro penzvimbo, ichiwedzera kuwedzera kwayo kupisa kwekupisa.

Pane rimwe divi,aluminium foaminewo inoshamisa thermal conductivity properties. Thermal conductivity yealuminium inenge 200 W/m·K. Haisi iyo inofambisa kupisa semhangura, asi ichiri inoshanda yekupisa conductor. Aluminium foam haina huremu uye inokodzera uremu-kuziva maapplication akadai seaerospace uye maindasitiri emotokari. Kuramba kwayo kwecorrosion uye kusimba kunoita kuti ive sarudzo yakakurumbira yekutonhodza munzvimbo dzakaoma.

Nekuenzanisa kupisa kwekupisa kwemhangura furo uye aluminium furo, zvinogona kunyatsoonekwa kuti foam yemhangura ine yakakwirira yekupisa conductivity, ichiita kuti inyatsoshandakupisa kupisa. Nekudaro, pane zvimwe zvinhu zvekufunga nezvazvo pakusarudza pakati pezvinhu zviviri zvekushandisa zvinopisa. Semuyenzaniso, zvinodikanwa-zvakanangana nekushandisa, senge kurema, kuramba ngura, uye mutengo, zvakare zvinopesvedzera kusarudzwa kwefuro resimbi.

Pamusoro pekupisa kwekupisa, dhizaini uye kugadzirwa kwesimbi foam inoitawo basa rakakosha mukukwanisa kwayo kubvisa kupisa. Iyo porosity, saizi yepore, uye chimiro chese chefuro chinogona kukanganisa zvakanyanya kuita kwayo kupisa. Zvosefoam yemhangura uye aluminium foaminogona kugadzirwa neakasiyana porosity uye pore saizi kuti ikwidzise mashandiro avo ekupisa kune chaiwo maapplication.

Pamusoro pezvo, kufambira mberi mune zvesainzi zvesainzi uye mainjiniya kwakatungamira mukugadzirwa kwemasanganiswa esimbi mafuro anosanganisa zvakanakira mhangura nealuminium. Aya ma hybrid foam anopa chiyero pakati pekupisa conductivity, uremu uye mutengo, zvichiita kuti ive yakakodzera kune akasiyana siyana ekutonhodza maapplication.

Muchidimbu, nepo foam yemhangura ine yakakwirira yekupisa yekupisa uye ichibvisa kupisa zvakanyanya kupfuura aluminium furo, sarudzo pakati pezvinhu zviviri izvi pakupedzisira zvinoenderana nezvinodiwa uye zvipimo zvekushandisa. Zvosefoam yemhangura uye aluminium foamvane yavo yakasarudzika zvivakwa uye zvakanakira, uye sezvo zvinhu zvesainzi zvichiramba zvichifambira mberi, maindasitiri ave nesarudzo dzakawanda dziripo dzekugadzirisa kupisa kupisa.
