Ngexesha le nyanga I-Raspberry Foundation ibhengeze ibhodi yayo entsha yeRaspberry 4 eza nexabiso elifanayo nenguqulo yayo yangaphambili kodwa yongeza uphuculo oluninzi (Ungajonga upapasho apha).
Emva kweendaba zesimo sayo kuluntu jikelele, iingxaki ezahlukeneyo zaqala ukwaziswa inxulumene neRaspberry 4 kwaye yeyokuqala kubo Ngeengxaki ezinxulumene neentambo zohlobo C lwe-USB, kuba ayizizo zonke ezibaqondayo njengomthombo wamandla kodwa njengesixhobo esinye (iaudiyo). Ngoku enye ingxaki kule bhodi iye yaziwa.
Kwaye oko Umsebenzisi ogama linguJeff Geerling, uthi ngoku iRaspberry 4 ifuna umthombo wokupholisa (fan).
Kudala ndisebenzisa uPi kwiiprojekthi ezahlukeneyo ukusukela oko zaziswa ngo-2012, nakwiimodeli ezininzi, kubandakanya nePi Zero encinci kunye nohlaziyo olwahlukileyo lwe-A +, awudingi fan ukuba uphephe ukuqhubekeka kwiprosesa.
Kwaye imaging eshushu okanye imilinganiselo yamabala kusetyenziswa ithemometha ye-infrared ngokubanzi ibonise i-SoC ikhupha obona bushushu.
Nangona kunjalo, i-Raspberry Pi 4 yahlukile kuba iprosesa ayitshisi nje kuphela, naphantsi komthwalo oqhelekileyo, kodwa kukho ezinye izinto ebhodini ezishushu zide zifike kwinqanaba lokuba kungabi lula ukubamba.
Nanku umfanekiso oshushu othathwe ngekhamera yakho yokucinga eshushu, eqaqambisa iinxalenye zeRaspberry Pi 4 evelisa obona bushushu emva kwemizuzu emi-5.

Uninzi lwenu lunokucinga njalo ukufudumeza ibhodi kuyinto eqhelekileyo kwaye kwimeko yesiqhelo ewe, kodwa kwimeko yeRaspberry Pi 4 idlula imida yokufudumeza "ngesiqhelo" Ayikuthinteli nje ekufumaneni esona santya siphezulu sinokunikezelwa yiprosesa, kodwa ikwathetha ukuba imisebenzi yakho iya kuthatha ixesha elide, ukongeza ekufikeleleni kwimisebenzi enyanzelekileyo iqondo lobushushu lonyuka ngakumbi kwaye linokubeka esichengeni izinto kwixesha elide.
Oku kubonisa ukuba iinxalenye ezingaphakathi kweRaspberry Pi (Ngokwesiqhelo iprosesa, kodwa mhlawumbi abanye) Batshisa ngokwaneleyo ukufikelela kwimida yabo yokhuseleko lwangaphakathi.
Iprosesa yayikwi-60 ° C, Nangona inxenye yesinyithi sesinyithi sinceda ekusasazeni obu bushushu kujikeleze umjikelezo kunye nomfanekiso we-IR, ubushushu obuphuma phezulu kwi-CPU.
Iindawo ezimhlophe eziqaqambileyo emazantsi ekhohlo UJeff uthi eli candelo lekhadi phantse lihlala likhupha ubushushu obuninzi. kwaye izinto ezikule ndawo azisasazi njengeprosesa.
Okokugqibela, uphawula ukuba ukuba kukho nawuphi na umsebenzi kwizibuko le-USB, eli nxalenye lifikelela kuma-60 nama-70 ° C.
Nangona uhlaziyo lwamva nje lwenkqubo (iRaspbian) lunokunceda ukugcina le chip ipholile, isaza kushushu phantsi komthwalo.
«Emva koko cinga ukuba usebenzisa iPi 4 endaweni yekhompyuter yedesktop, ubuncinci idiski engaphandle ye-USB 3.0 eqhagamshelwe, iWiFi exhunyiwe kwaye idlulisa isixa esikhulu sedatha, ikhibhodi ye-USB kunye nempuku kunye nomsebenzi weewindows ezininzi kwisikhangeli. , umhleli wokubhaliweyo kunye nesidlali somculo.
Eli nani lomthwalo lanele ukwenza ukuba iprosesa ikhawuleze ngaphantsi kwemizuzu eli-10.
Nangona kunjalo, uJeff uthi ukubukela iividiyo, ukuskrolela kwiindawo ezinzima ngakumbi kunye nokutshintsha rhoqo izicelo zihlala zibangela ukuba iprosesa ikhawuleze ifikelele kubushushu obufikelela kuma-80 degrees celcius, ngakumbi ukuba ikwi-classic evaliweyo engenanto, engenatyala.
“Kuvavanyo lwam olusemthethweni, ndiqale ukusebenzisa uxinzelelo -cpu 4 ukufumana iprosesa ukuba yenze umsebenzi omninzi, ngokuqhubekekayo. Emva kwemizuzu embalwa, ndisebenzisa i-vcgencmd measure_temp kunye ne-Vcgencmd get_rottled, ndabona ukuba iprosesa iqale ukucothisa nje ukuba ifike kwi-80 ° C (176 ° F) »
Ekugqibeleni uJeff wabelana ngevidiyo ngendlela onokongeza ngayo ifeni (fan) kwimeko yeRaspberry Pi kwaye ngokusombulula le ngxaki.
Ukuba ufuna ukwazi ngakumbi ngayo, unokujonga ukupapashwa kwayo kwikhonkco elilandelayo.
