Umklamo Weshaja Ngokushaja Okune-Magnetic
Ukuthuthukiswa kwamadivayisi kagesi eselula kuyashesha, kusukela kuma-smartphone nama-smartwatch kuya kuma-earbud angenantambo ngisho namadivayisi e-Internet of Things (IoT). Njengoba ukuhamba kukhuphuka, nesidingo sezindlela zokushaja ezisebenzayo, eziphephile, nezihlala isikhathi eside siyanda. Enye indlela ethandwa kakhulu ukuklama amashaja ane-magnetic charging. Lobu buchwepheshe busebenzisa i-magnetic drawing ukuhola indawo yesixhumi noma ikhoyili yokushaja ukuze kube nokunemba okukhulu, kuncishiswe ukuguguleka kwe-port futhi kwandise induduzo yomsebenzisi.
Kuyini Ukushaja Nge-Magnetic?
Ukushaja ngemagnethi ngokuvamile kubhekisela ezinhlelweni zokushaja ezisebenzisa omayintshi njengendlela yokuvumelanisa phakathi kweshaja nedivayisi. Kweminye imiklamo, omayintshi basetshenziselwa ukukhiya isixhumi esibonakalayo (njengezixhumi zemagnethi kwamanye ama-laptop nezesekeli). Kweminye imiklamo, omayintshi basiza ukuvumelanisa amakhoyili ekushajeni okungenantambo, okwandisa ukusebenza kahle kokudlulisa amandla.
Kubalulekile ukuqaphela ukuthi "i-magnetic" akusho ukuthi amandla kagesi adluliselwa kuphela ngensimu yamagnetic ngaphandle kwanoma yisiphi esinye isakhiwo. Empeleni, kunezindlela ezimbili eziyinhloko:
1. Isixhumi sikamazibuthe esihlanganiswe nokuxhumana kukagesi (izikhonkwane ze-pogo noma ama-contact pad)
Ugesi ugeleza ngokuxhumana kwensimbi, kuyilapho omakethi begcina isixhumi sinamathele futhi sizinzile.
2. Ukushaja okungenantambo okungenisa umoya ngosizo lwama-magnet
Amandla adluliselwa ngokufakwa kwe-electromagnetic phakathi kwekhoyili yokudlulisela (eshaja) kanye nekhoyili yokwamukela (edivayisini), futhi omakethi baqinisekisa ukuthi amakhoyili amabili aqondile.
Zombili lezi zindlela zihlose ukuthuthukisa ukusetshenziswa kalula, kodwa zinemiphumela ehlukile yokuklama.
Izinzuzo Zomklamo Weshaja Kamagnetic
Ukusetshenziswa kwamagnethi ezinhlelweni zokushaja kunikeza izinzuzo eziningana ezibalulekile:
– Kulula ukufaka: abasebenzisi akudingeki baqondise amachweba amancane; omakethi “bazodonsa” isixhumi noma basize ekuhleleni indawo.
– Umonakalo wembobo onciphile: ngezixhumi ezisebenza ngogesi, idivayisi ayidingi ukuxhumeka nokukhishwa njalo; ingozi yokuthi imbobo ikhululeke, iphuke, noma ingcole iyancipha.
– Ukuphepha uma kubanjwa: uma ikhebula lidonswa ngokuzumayo, isixhumi esinozibuthe ngokuvamile sizokhululeka ngaphandle kokuwisa idivayisi.
– Ukusebenza kahle okwandisiwe (kwe-wireless): ukuhambisana kahle kunciphisa ukulahleka kwamandla, kunciphisa ukushisa, futhi kusheshise ukushaja.
Noma kunjalo, imiklamo yamagnetic ayiyona engcono ngaso sonke isikhathi kuzo zonke izimo. Idinga ukwakheka okucophelelayo kwemishini, kagesi, kanye nokushisa ukuqinisekisa ukuphepha nokuthembeka.
Izimiso Zokuklama: Okwemishini, Okukagesi, Nokushisa
1. Umklamo Wemishini: Ukuqondanisa kanye Nokuqina Kokunamathela
Ngamashaja kazibuthe, inselele enkulu ukukhiqiza amandla okudonsa aqinile ngokwanele ukubamba ishaja endaweni yayo, kodwa angaqinile kangangokuthi enza ukususwa kube nzima noma kungakhululeki kumsebenzisi.
Izinto okufanele uzicabangele:
– Indawo kamazibuthe: umazibuthe kumele ubekwe ngokulinganayo ukuze idivayisi ingatsheki.
– Ukubekezelelana kokukhiqiza: ibanga phakathi kwamagnethi, ukujiya kwekhava, kanye nendawo yekhoyili/yokuxhumana kuthinta ukusebenza.
– Izinto zokufaka ikheyisi: ipulasitiki ngokuvamile iphephile kuma-magnetic field, kuyilapho insimbi ingathinta insimu futhi yandise ukushisa kwamanje kwe-eddy kumiklamo engenantambo uma ingaklanywanga kahle.
Amaphini e-Pogo avame ukusetshenziswa ekwakhiweni kwezixhumi ezisebenza ngogesi ezinezixhumi ngoba ahlinzeka ngokuxhumana okuhle ngisho noma kungaqondani kahle. Isimo sesixhumi sivame futhi ukuklanywa "ngokufaka" ngomshini ukuvimbela ukuqondiswa okuphambene.
2. Umklamo Kagesi: Ukulawula Kwamanje, Ukuvikela, kanye Nokuxhumana
Ezixhumini zikagesi ezixhumene ngqo nogesi, izici zikagesi zifana nezeshaja yekhebula evamile, kodwa kunezinye izidingo:
– Ukuvikelwa kwe-short-circuit: Uma isixhumi sikamazibuthe sivuliwe, iphedi yokuxhumana ingathintana nezinto zensimbi (izihluthulelo, izinhlamvu zemali). Ngakho-ke, kudingeka isekethe yokuvikela, njengokutholwa komthwalo ngaphambi kokusebenzisa i-voltage.
– Ukulawulwa kwamanje kanye ne-voltage: Amadivayisi esimanje ngokuvamile adinga ukushaja okulawulwayo (i-CC/CV yamabhethri e-Li-ion). Umklamo kufanele ufake i-IC yokulawula ukushaja kanye nenzwa yokushisa.
– Ukuhlonza ishaja: ezinye izinhlelo zengeza i-resistor yokuhlonza noma ukuxhumana okulula ukuze idivayisi ibone i-adaptha efanele.
Emiklamo engenantambo engenisa umoya, ukugxila kuhlukile:
– Imvamisa yokusebenza kanye nokuzwakala kwezwi: ukukhetha imvamisa, usayizi wekhoyili, kanye ne-capacitor yokuzwakala kwezwi kunquma ukusebenza kahle.
– Ukutholwa Kwezinto Zangaphandle (i-FOD): ukuvimbela izinhlamvu zemali noma izinto zensimbi ekushiseni ngokweqile endaweni yokushaja.
– Ukulawulwa kwamandla okuzivumelanisa nezimo: amandla anikezwa njengoba kudingeka, aqashwe ngokuxhumana phakathi komthumeli kanye nomemukeli.
3. Umklamo Wokushisa: Ukuphatha Ukushisa
Ukushisa kuyisitha esiyinhloko samabhethri kanye nezinto zikagesi zokushaja. Ukushaja kukazibuthe—ikakhulukazi ukushaja okungenantambo—kuvame ukukhiqiza ukushisa okuningi kunokushaja ngentambo, ikakhulukazi uma ukulungiswa kungalungile.
Izixazululo ezivamile zokushisa:
– ukwengeza i-heat spreader (ishidi le-graphite, i-aluminium ethile enomklamo ophephile),
– ukungenisa umoya okungenamsebenzi ngokusebenzisa umklamo wekhava,
– nciphisa amandla njengoba izinga lokushisa likhuphuka,
– thuthukisa ukuhambisana nama-magnet ukuze kuncishiswe ukulahleka kwamandla.
Izingxenye Eziyinhloko Kushaja Ye-Magnetic
Nazi izingxenye ezivame ukutholakala ekwakhiweni kweshaja okusekelwe kumagnetic:
1. Umazibuthe ohlala njalo (ngokuvamile i-neodymium): umazibuthe ojikelezayo noma omazibuthe abaningana abancane.
2. Isixhumi/ikhoyili:
– iphinikhodi ye-pogo + iphedi yokuxhumana (yokuxhumana ngqo), noma
– ikhoyili yokudlulisa (ishaja) kanye nekhoyili yokwamukela (idivayisi) yokungenisa.
3. Isekethe yokulawula amandla:
