"Kutheni itshaja ye-2.4A enye, imarike iya kuba namaxabiso ahlukeneyo avela?"
Ndiyakholelwa ukuba abahlobo abaninzi abathenge iiselfowuni kunye neetshaja zekhompyutha baye baba namathandabuzo anjalo. Kubonakala ngathi ngumsebenzi ofanayo wetshaja, ixabiso lidla ngokuba ngumahluko wehlabathi. Ngoko kutheni oku kunjalo? Uphi umahluko kwixabiso? Yintoni endimele ndiyithathele ingqalelo xa ndikhetha itshaja? Namhlanje ndiza kukucombulula le mfihlelo.
1 Iprimiyamu yophawu
Iitshaja kwimarike zinokuhlelwa zibe ziindidi ezintathu: iibrendi zoqobo, zomntu wesithathu, iintlobo ngeentlobo zeetshaja. Ngokubanzi, ngokwexabiso kwirenki, imvelaphi > iibrendi zomntu wesithathu > iintlobo ezahlukeneyo.
Itshaja yantlandlolo ekuthengeni iindawo eziphambili ziya kuza nazo, kodwa kukho ezinye iibrendi ezingathumeliyo, ezinje ngeApple, kwaye ngenxa yeprimiyamu yophawu, ixabiso lidla ngokuba phezulu xa uthenga.
Iimpawu zomntu wesithathu ziimveliso eziveliswa ziimpawu zedijithali zobuchwephesha, isitayile sahluke kakhulu kunesokuqala, ixabiso likwafikeleleka ngakumbi, libe lukhetho lwabathengi abaninzi. Nangona kunjalo, umgangatho weempawu zomntu wesithathu nazo ziphezulu kwaye ziphantsi, abavelisi abakhulu, ngokusebenzisa isiqinisekiso esigunyazisiweyo seemveliso kukhuseleko olukhuselekileyo.
Itshaja yindawo yokutyela ecaleni kwendlela kuyo yonke indawo yokutshaja, awuyazi into eveliswa ngayo, ezi mveliso zihlala zibangelwa yi-crotch yezinto okanye ubugcisa oburhabaxa kunye neengozi zokhuseleko, akukhuthazwa ukuba ukhethe.
2. Izinto ezahlukeneyo kunye nomsebenzi
Musa ukujonga itshaja encinci, uyilo lwangaphakathi lwesekethe, izixhobo kunye noyilo lomsebenzi, yinkathalo enkulu. Iitshaja ezikumgangatho ophezulu, ubume bangaphakathi bezinto ezipheleleyo, ezenziwe kakuhle, ixabiso eliphezulu ngokwemvelo. Kwaye iitshaja ezikumgangatho ophantsi ukwenzela ukunciphisa iindleko zihlala zicutheka kwii-transformers, iingcingo, ii-capacitors kunye ne-inductors.
Ngokomzekelo, i-transformer yangaphakathi, iitshaja ezisemgangathweni ziya kusebenzisa ukuhanjiswa okulungileyo, umthamo ophezulu wangoku ophetheyo, uzinzo lwe-thermal yezinto ezihlambulukileyo zobhedu, kunye neetshaja ezixubileyo zihlala zigubungele izinto ze-aluminiyam zobhedu, ukuhanjiswa okuphantsi, ukuzinza kwe-thermal buthathaka.
Omnye umzekelo yibhodi yoshicilelo, iitshaja ezisemgangathweni ziya kusebenzisa ubushushu obuphezulu, idangatye elibuyiswayo, iibhodi zesekethe ezinganyangekiyo kwiPCB, ngelixa iitshaja ezixubeneyo zihlala zikumgangatho ophantsi, zinokutsha kwaye kulula ukwaphuka, inqanaba lelahleko yesekethe liphezulu ibhodi yePCB yefiber. . Ukusetyenziswa kwexesha elide kusenokonakalisa ibhetri yefowuni, kwaye kukhokelela ekutsha okuzenzekelayo, ukuvuza kunye nezinye iingozi zokhuseleko.
3. Inani lojongano lahlukile
Ukongeza kwiitshaja zethu eziqhelekileyo ezisetyenziswa kwizibuko elinye, abasebenzisi abaninzi ngoku bakwasebenzisa iitshaja ezinezibuko ezininzi.
Inzuzo yeetshaja ezininzi zezibuko kukuba xa ufuna ukuhlawulisa izixhobo ezininzi ngexesha elinye, kodwa itshaja enye kuphela okanye iplagi ayinakho ukuhlalisa iitshaja ezininzi, yisebenzise ngesivumelwano esenziweyo.
