Njengesixhobo esiphambili sothutho lwetsheyini ebandayo, ukukhetha isemi{0}}yenqwelo erhuqwayo efrijiweyo kubalulekile. Xa ukhetha itreyila, qwalasela imiba emithathu engundoqo: i-chassis yetreyila, umzimba ogqunyiweyo, kunye neyunithi yesikhenkcisi.
Ukubaluleka koKhetho lweChassis
I-chassis ichaphazela ukuthwala kwesithuthi, ukusetyenziswa kwamafutha kunye nemigangatho yokukhupha. Khetha i-chassis ethembeke kakhulu kwaye inikezela ngokukhawuleza ukuthintela ukungasebenzi kakuhle okunokubangela ukuwohloka kwempahla. Okokuqala, ukhetho lwe-chassis lubalulekile. Ichaphazela ngokuthe ngqo umthamo wesithuthi, ukusetyenziswa kwamafutha kunye nemigangatho yokukhupha izinto ezikhutshwayo. Ngaphaya koko, njengoko iisemi{4}}iitreyila ezikhenkcezisiweyo zihambisa imithwalo ngokukhawuleza kwaye ayinakugcinwa ixesha elide, ukuthembeka kwe-chassis kubaluleke kakhulu ukunqanda ukungasebenzi kakuhle okunokubangela ukuwohloka komthwalo.
Iikhrayitheriya zokuKhetha uMzimba
Okwesibini, umzimba kufuneka ube nokutywinwa okugqwesileyo kunye neempawu zokufakelwa kwe-thermal. Isixhobo kufuneka sibe nokufunxwa kwamanzi asezantsi, ukuphefumla, kwaye kungadleki{1}}kukwazi ukumelana neentlobo ezahlukeneyo zomthwalo. Umzimba ufuna ukutywinwa okugqwesileyo kunye nokufakelwa kwe-thermal ukuqinisekisa ubushushu obuzinzileyo bempahla ngexesha lokuhamba. Xa ukhetha umzimba, qwalasela ukufunxwa kwamanzi, ukuphefumla, ukuhanjiswa kwe-thermal, kunye nokuxhathisa ukubola. Ngaphaya koko, iintlobo ezahlukeneyo zomthwalo ziya kuba neemfuno ezahlukeneyo zenqwelwana, ngoko ke ukhetho kufuneka lusekelwe kwiimfuno zokwenyani.
UKhetho lweYunithi yesikhenkcisi
Ekugqibeleni, iiyunithi zefriji zihlulwe zibe ziintlobo ezizimeleyo kunye nezixhomekeke. Xa ukhetha iyunithi yefriji, kubalulekile ukulungelelanisa iimfuno zokuthutha ukuphepha iindleko eziphezulu. Ukhetho lweyunithi yesikhenkcezisi lukwangumba ophambili ekumiseleni ukusebenza kwesemi{2}}erhuqwayo efakwe efrijini. Iiyunithi zefriji zihlelwa njengezizimeleyo kwaye zixhomekeke. Iiyunithi ezizimeleyo zinemithombo yazo yamandla, ngelixa iiyunithi ezixhomekeke kumandla we-chassis yesithuthi. Xa ukhetha iyunithi yesikhenkcisi, kubalulekile ukulungelelanisa iimfuno zokuhamba ukuphepha iindleko zokuthutha ezingeyomfuneko.
