Ukunyuka kobushushu sisalathiso esibaluleke kakhulu sokusebenza kwemoto.Ukuba ukusebenza kokunyuka kwamaqondo obushushu akulunganga, ubomi benkonzo kunye nokuthembeka kokusebenza kwemoto kuya kuncitshiswa kakhulu.Izinto ezichaphazela ukunyuka kwamaqondo obushushu bemoto, ukongeza kukhetho lweeparamitha zoyilo lwemoto ngokwayo, izinto ezininzi kwinkqubo yokuvelisa ziya kubangela ukunyuka kobushushu bemoto ukuba kungafezekisi iimfuno zokusebenza ngokukhuselekileyo kwemoto.

Ukuvavanya ukunyuka kweqondo lokushisa kwemoto, kuyimfuneko ukwenza uvavanyo lokunyuka kweqondo lokushisa kwe-thermal, kwaye akunakwenzeka ukufumana ingxaki yokunyuka kweqondo lokushisa kwemoto ngovavanyo olulula lwefektri.Inani elikhulu lokwenyani ubushushu obuzinzileyo beemvavanyo zokunyuka kobushushu beenjini bubonisa ukuba: ukhetho olungafanelekanga lwabalandeli kunye nezinto ezingafanelekanga zobushushu zinempembelelo enkulu ekunyukeni kobushushu, kodwa ingxaki yokunyuka kwamaqondo obushushu okubangelwa yimiba yokudipha isoloko idibana, kunye nonyango oluqhelekileyo. kukudipha kwakhona iPeyinti kanye.

Ukuze kuphuculwe ukusebenza kakuhle kwemveliso, uninzi lweenjini ezincinci kunye neziphakathi azinayo ipeyinti yokudipha isiseko.Ukongeza kumgangatho wokudipha kunye nokomisa kwe-winding ngokwayo, ukuqina kombindi wentsimbi kunye nesakhelo sikwachaphazela ngokuthe ngqo ukunyuka kobushushu bokugqibela kwemoto.Ngokwethiyori, umphezulu wokukhwelana wesiseko somatshini kunye nombindi wentsimbi kufuneka uhambelane ngokusondeleyo, kodwa ngenxa yokuguqulwa kwesiseko somatshini kunye nesiseko sentsimbi, njl. ehambelana nemoto.I-Thermal insulation yokuchithwa kobushushu.Ukusetyenziswa kwepeyinti yokudipha ngesakhelo akugcini nje ukuzalisa isithuba somoya phakathi kweendawo zokukhwelana, kodwa kwakhona kuthintela izinto ezinokuthi zonakalisa i-motor winding ngexesha lenkqubo yokuvelisa ngenxa yokukhusela i-casing.Ulawulo lokuphakamisa lunomphumo othile wokuphucula.

Ukuhanjiswa kobushushu kubizwa ngokuba kukuqhutywa kobushushu.Inkqubo yokudlulisa ubushushu phakathi kwezinto ezimbini ezidibanayo kunye namaqondo obushushu ahlukeneyo, okanye phakathi kweendawo ezahlukeneyo zobushushu zento enye ngaphandle kokufuduswa kwe-macroscopic, ibizwa ngokuba yi-heat conduction.Ipropathi yento yokwenza ubushushu ibizwa ngokuba yi-thermal conductivity yento.Ukugqithiswa kobushushu kwizinto eziqinileyo kunye nakulwelo oluselulo kukuqhuba kwe-thermal kuphela.Inxalenye ye-thermal conductive ibandakanyeka ekugqithiseni ubushushu kwi-fluid ehambayo.

I-Thermal conduction ixhomekeke kwintshukumo ye-thermal yee-electron, ii-athomu, iimolekyuli kunye neelethisi kwizinto zokuhambisa ubushushu.Nangona kunjalo, iipropati zezixhobo zihluke, iindlela eziphambili ze-thermal conduction zihluke, kwaye imiphumo nayo ihluke.Ngokuqhelekileyo, i-thermal conductivity yesinyithi inkulu kuneye-non-metals, kwaye i-thermal conductivity yesinyithi ecocekileyo inkulu kune-alloys.Phakathi kwamazwe amathathu ezinto, i-thermal conductivity yesimo esiqinileyo yeyona inkulu, ilandelwa yimeko yolwelo kunye neyona incinci kwimo yegesi.

Ukufakwa kwe-thermal okanye izinto zokufakelwa kwe-thermal zihlala zisetyenziselwa ukwakhiwa, amandla okushisa, iteknoloji ye-cryogenic.Uninzi lwazo zizinto eziphathekayo, kwaye umoya ophethe i-thermal conductivity ugcinwe kwiipores, ngoko banokudlala indima yokufudumala ukushisa kunye nokugcinwa kobushushu.Kwaye zonke ziyi-discontinuities, kwaye ukuhanjiswa kobushushu kukho zombini ukuqhutyelwa kobushushu kwe-skeleton eqinile kunye nomoya, kunye nokuhamba komoya kunye nemitha.Kubunjineli, i-thermal conductivity eguqulelwe ngolu tshintsho lobushushu oludibeneyo lubizwa ngokuba yi-conductivity ebonakalayo ye-thermal.I-conductivity ye-thermal ebonakalayo ayichaphazeli kuphela ukubunjwa kwezinto eziphathekayo, uxinzelelo kunye nobushushu, kodwa kunye nobuninzi bezinto kunye nomxholo womswakama.I-density ephantsi, i-voids encinci kwizinto eziphathekayo kwaye iyancipha i-conductivity ebonakalayo ye-thermal.Nangona kunjalo, xa uxinaniso luncinci ukuya kumlinganiselo othile, kuthetha ukuba i-voids yangaphakathi iye yanda okanye idibaniswe enye kwenye, ibangela ukuhanjiswa komoya wangaphakathi, ukunyusa ukuhanjiswa kobushushu, kunye nokunyuka kwe-thermal conductivity.Ngakolunye uhlangothi, ii-pores kwi-thermal insulation material zilula ukufunxa amanzi, kwaye ukufuduka kunye nokufuduka kwamanzi phantsi kwesenzo se-gradient yeqondo lokushisa kwandisa kakhulu ukubonakala kwe-thermal conductivity.
