Mukuvhenekera kwekunze kwemafashama, Mwenje Yekuchengetedza Kumba inoita basa rakakosha.Dzimwe nguva dzakakosha, dzakadai sekuvhenekera kwezvikwere, mharadzano, dzimwe nzvimbo, nezvimwewo, nekuda kwehunhu hwavo, kana mwenje Zvinodiwa, dzimwe nguva magetsi emagetsi anowanzo kudiwa.Kare, mapurojekiti mazhinji ekuvhenekesa akashandisa mwenje we-high-pressure sodium ine chimiro chemisoro yakawanda yemarambi kuti isangane nezvinodiwa zvekuvhenekesa.
Hunhu hweiyo radiator yemwenje ndiyo yekutanga nyaya inobata zvakananga saizi yekuora kwechiedza.Nzira nhatu dzakakosha dzetekinoroji yekupisa kupisa uye kupisa kupisa kwemba yemwenje ndeiyi: conduction, convection uye radiation.Iyo yekupisa manejimendi inotangirawo kubva kune aya matatu maficha, ayo akakamurwa kuita ongororo yenguva pfupi.Uye steady-state analysis.Nzira huru yekufambisa yeradiator ndeye conduction uye convection heat dissipation, uye iyo inopenya kupisa kupisa pasi pechisikigo convection haigone kufuratirwa.Zvigadziriso zvemwenje zvinonyanya kushandisa ma-high-power LEDs.
Parizvino, kupenya kunopenya kwekutengeserana kwepamusoro-simba LEDs inongova 15% kusvika 30%, uye yakawanda yesimba rinosara rinoshandurwa kuita kupisa simba.Kana simba rekupisa risingakwanisi kubudiswa zvakanaka, rinotungamirira kumigumisiro yakakomba.Tembiricha yepamusoro inoderedza kupenya kupenya uye kupenya kwe LED, kukonzeresa mwenje wave redshift, kukanda kwemavara, uye zvakare kukonzeresa zvakaipa zvakadai sekuchembera kwechishandiso.Chinhu chinonyanya kukosha ndechekuti hupenyu hwe LED huchaderedzwa zvakanyanya, nekuda kwekuora kwechiedza che LED kana hupenyu hwayo.Iyo yakanangana neiyo junction tembiricha.Kana kupisa kwekupisa kusina kunaka, kupisa kwejunction kuchava kwakakwirira uye hupenyu huchava hupfupi.Maererano nemutemo weArrhenius, hupenyu huchawedzerwa ne2 nguva kune yega 10 ° C kuderera kwekushisa.
