Phakathi nesikhathi sale nyanga I-Raspberry Foundation imemezele ibhodi yayo entsha ye-Raspberry 4 eza nentengo efanayo nenguqulo yayo yangaphambilini kepha ingeze ukuthuthuka okuningi (Ungahlola ukushicilelwa lapha).
Ngemuva kwezindaba zesimo sayo emphakathini jikelele, izinkinga ezahlukahlukene zaqala ukwenziwa zaziwe ehlobene no-Raspberry 4 futhi ngukuthi owokuqala wabo wayengu ngezinkinga ezihlobene nezintambo ze-USB Type-C, ngoba akubona bonke abababona njengomthombo wamandla kepha njengesesekeli esisodwa (umsindo). Manje sekuvele enye inkinga ngaleli bhodi.
Futhi yilokho umsebenzisi ogama lakhe linguJeff Geerling, uveza ukuthi manje iRaspberry 4 idinga umthombo wokupholisa (fan).
“Bengisebenzisa iPi kumaphrojekthi ahlukahlukene selokhu yethulwa ngo-2012, nakumamodeli amaningi, kufaka phakathi iPi Zero encane nokubuyekezwa okuhlukahlukene kwe-A +, awudingi ngisho nomlandeli ukugwema ukuqunjelwa yiprosesa.
Futhi izilinganiso ezishisayo noma izilinganiso zamabala usebenzisa i-thermometer ye-infrared ngokuvamile kukhombisa i-SoC ekhipha ukushisa okukhulu.
Kodwa-ke, i-Raspberry Pi 4 yehlukile ngoba iprosesa ayishisi nje kuphela ngokuphawuleka, noma ingaphansi komthwalo ojwayelekile, kepha kunezinye izinto ebhodini ezishisa zize zifike ezingeni lokuthi kungabi lula ukuzithinta.
Nasi isithombe esishisayo esithathwe ngekhamera yakho ye-imaging yokushisa egqamisa izingxenye zeRaspberry Pi 4 ezikhiqiza ukushisa okukhulu ngemuva kwemizuzu engu-5.
okusajingijolo-pi-4-okushisayo
Abaningi benu bangacabanga lokho ukufudumeza kwebhodi kuyinto ejwayelekile futhi ezimeni ezijwayelekile yebo, kepha esimweni seRaspberry Pi 4 yeqa imikhawulo yokushisa "okujwayelekile" Akugcini nje ukuthi kukuvimbe ekutholeni isivinini esiphezulu iprosesa engakunikeza, kepha futhi kusho ukuthi imisebenzi yakho izothatha isikhathi eside, ngaphezu kokufinyelela ekusebenzeni okuphoqelelwe izinga lokushisa lenyuka kakhulu futhi lingahlehlisa izinto esikhathini esizayo.
Lokhu kukhombisa ukuthi izingxenye ezingaphakathi kwe-Raspberry Pi (imvamisa nje iprosesa, kepha mhlawumbe abanye) bashisa ngokwanele ukufinyelela imingcele yabo yokuphepha yangaphakathi.
Iprosesa yayicishe ibe ngu-60 ° C, Yize ngokwengxenye isigaxa sensimbi sisiza ekusakazeni lokhu kushisa okuzungeze umjikelezo nasesithombeni se-IR, ukushisa okuphuma phezulu kwe-CPU.
Izindawo ezimhlophe ezikhanyayo kwesokunxele esingezansi UJeff uthi le ngxenye yekhadi cishe njalo ikhipha ukushisa okukhulu. futhi izinto ezikule ndawo azisabalali njengomprosesa.
Ekugcineni, uphawula ukuthi uma kukhona okwenziwayo emachwebeni e-USB, le ngxenye ifinyelela ku-60 no-70 ° C.
Yize ukuvuselelwa kwesistimu kwakamuva (iRaspbian) kungasiza ukugcina le chip ipholile kancane, isazoshisa ngaphansi komthwalo.
«Bese ucabanga ukuthi empeleni usebenzisa iPi 4 esikhundleni sedeskithophu yedeskithophu, okungenani ixhunywe i-USB 3.0 hard drive yangaphandle, i-WiFi ixhunyiwe futhi idlulisa inani elikhulu lemininingwane, ikhibhodi ye-USB negundane kanye nomsebenzi wamawindi amaningi kusiphequluli , umhleli wombhalo nesidlali somculo.
Leli nani lomthwalo lanele ukwenza ukuthi iprosesa isheshise ngaphansi kwemizuzu eyi-10.
Kodwa-ke, uJeff uthi ukubuka amavidiyo, ukuskrola kumasayithi ayinkimbinkimbi nokushintsha izinhlelo kaningi kuvame ukudala ukuthi iprosesa ifinyelele masinyane ezingeni lokushisa elifinyelela kuma-80 degrees Celsius, ikakhulukazi uma ikwi-Case eseplastikhi eboshwe ngokuphelele, engenapulasitiki.
“Ekuhlolweni kwami okuhlelekile, ngiqale ukusebenzisa ingcindezi –cpu 4 ukuthola iprosesa lokwenza umsebenzi omningi, ngokuqhubekayo. Ngemuva kwemizuzu embalwa, ngisebenzisa i-vcgencmd measure_temp kanye ne »Vcgencmd get_throtled, ngibonile ukuthi iprosesa iqale ukwehlisa ijubane lapho nje ifika ku-80 ° C (176 ° F)»
Ekugcineni uJeff wabelane ngevidiyo yokuthi ungangeza kanjani fan (fan) ecaleni le-Raspberry Pi futhi ngaleyo ndlela uxazulule le nkinga.
Uma ufuna ukwazi kabanzi ngayo, ungabheka ukushicilelwa kwayo kusixhumanisi esilandelayo.
