1. Isisekelo:
Ukuhlukaniswa kwe-Fluid (imodi evamile)Amadivayisi amaningi okushintshanisa ukushisa kwezezimboni nezangaphandle ahlukanisa ngokuqinile uketshezi olushisayo nolubandayo ngokusebenzisa izindonga eziqinile ze-thermal conductivity (njengezindonga zamapayipi ensimbi, amapuleti ensimbi kathayela) ukuze kugwenywe ukuxubana nokungcoliswa koketshezi olubili, futhi avumele ukushisa ukuthi kudluliselwe odongeni kuphela; Ezimweni ezimbalwa ezikhethekile (njengemibhoshongo yokupholisa), uketshezi oluqondile lokuthintana kufanele kuhlangatshezwane nenqubo yokuxuba ukushisa kufanele kuhlangatshezwane nayo.
2.Amandla okushayela
Amandla okushayela: Umehluko wezinga lokushisa (ΔT)Amandla ashukumisayo okudlulisa ukushisa umehluko wezinga lokushisa phakathi koketshezi olushisayo nolubandayo. Uma umehluko omkhulu wezinga lokushisa umkhulu, izinga lokudlulisa ukushisa liyashesha.Inqobo nje uma kunomehluko wezinga lokushisa phakathi koketshezi olubili, ukudluliswa kokushisa kuzokwenzeka ngokuzenzakalelayo kuze kube yilapho umehluko wezinga lokushisa phakathi koketshezi olubili usondela ku-zero futhi kufinyelelwa ukulingana okuguquguqukayo, lapho ukudluliselwa kokushisa okuphumelelayo kuma ngokuyisisekelo.
3. Inqubo Eyinhloko
Inqubo Eyinhloko:Izinyathelo Ezintathu-Zokudlulisa Ukushisa Kwezinyathelo Sithatha isishintshi sokushisa esingaqondile esisetshenziswa kabanzi kakhulu njengesibonelo, ukudluliswa kokushisa kuhlanganisa izinyathelo ezintathu ezilandelanayo, asikho nesisodwa sazo esingashiywa:
- Ukudluliswa kokushisa kwe-convection (uketshezi → udonga): Uma uketshezi lwezinga lokushisa oluphezulu-lugeleza ohlangothini olulodwa lodonga, ama-molecule oketshezi ashayisana nodonga futhi adlulisele ukushisa odongeni. Ngesikhathi esifanayo, ukugeleza kwe-macroscopic (isiphithiphithi) soketshezi ngokuqhubekayo kudlulisa ukushisa kwangaphakathi odongeni. Lapho izinga lokugeleza lishesha futhi isiyaluyalu sinamandla, kulapho izinga lokushisa likhuphuka lisebenza kahle.
- Ukushisa (ngaphakathi kodonga): Ukushisa kwenziwa kusukela{1}kudonga oluseceleni lwezinga lokushisa eliphezulu ukuya{2}}obondeni oluseceleni lwezinga lokushisa eliphansi ngokusebenzisa ukudlidliza kwemolekyuli yento eqinile yodonga. I-thermal conductivity yento yodonga (njengethusi ne-aluminium, ene-thermal conductivity engcono kunensimbi engagqwali) kanye nobukhulu bodonga kanye nezinga lokungcolisa kuthinta ngokuqondile ukusebenza kahle kokuqhuba.
- Ukudluliswa kokushisa okuguquguqukayo (udonga → uketshezi): Udonga oluseceleni{1}}lwezinga lokushisa eliphansi ludlulisela ukushisa kuma-molecule{2}}ezinga lokushisa eliphansi eduze nodonga. Uketshezi lwezinga lokushisa eliphansi-luthwala ukushisa ngokugeleza kwalo, lugcine umehluko wezinga lokushisa phakathi kodonga noketshezi kanye nokuqinisekisa ukudluliswa kokushisa okuqhubekayo.
4. Ibhalansi Yamandla
Ibhalansi yamandla:Ukongiwa Kokushisa Ngaphansi kwezimo ezikahle (unganaki inani elincane lokulahlekelwa ukushisa), isamba sokushisa esikhishwa-uketshezi lwezinga lokushisa eliphezulu silingana nenani lokushisa elimuncwa uketshezi- lwezinga lokushisa eliphansi, oluvumelana nomthetho wokongiwa kwamandla. Njengoba ukushisa kudluliselwa, izinga lokushisa loketshezi oluphezulu-loketshezi oluphezulu, izinga lokushisa likhuphuka kancane kancane kanti izinga lokushisa liyancipha kancane kancane{4} bese lehla kancane kancane{4} phakathi kwalokhu okubili kuyancipha kancane kancane, ngaleyo ndlela kunciphisa izinga lokudlulisa ukushisa.
Isengezo
Umehluko Ezimisweni Ezisebenzayo Zezindlela Ezintathu Zokushintsha Ukushisa Ngokusekelwe ezigabeni ezivamile zomkhiqizo othekelisa ngaphandle, izimiso zokusebenza zezinhlobo ezihlukene zamadivayisi okushintshanisa ukushisa ziyahluka kancane. Izigaba eziyinhloko zimi kanje:
- Uhlobo olungaqondile{1}}lodonga:
Okusetshenziswa kakhulu (okufana negobolondo nohlobo lweshubhu, isishintshi sokushisa kwepuleti), ehlukanisa uketshezi olushisayo nolubandayo ngezindonga eziqinile futhi idlulise ukushisa ezinyathelweni ezintathu ezishiwo ngenhla. Uketshezi aluhlanganisi futhi lulungele izimo eziningi zezimboni.
- Ukukhiqiza kabusha:
Ukusebenzisa indawo yokugcina ukushisa okuqinile (njengezitini eziphikisayo) njengendawo ephakathi nendawo,{0}}izinga eliphezulu lokushisa eliphezulu kanye{1}}noketshezi olunezinga lokushisa eliphansi{1}}kugeleza ngokushintshana emzimbeni wesitoreji sokushisa ukuze kuzuzwe ukugcinwa kokushisa nokukhulula, okufanele izimo ezifana{2}}nokuthola ukushisa kwemfucumfucu yezinga lokushisa eliphezulu;
- Uhlobo lweHybrid:
Uketshezi olushisayo nolubandayo luxubene ngokuqondile ekuthintaneni, okuholela ekusebenzeni kahle kokudlulisa ukushisa kanye nesakhiwo esilula. Ifaneleka kuphela ezimeni lapho ukuxutshwa koketshezi kuvunyelwe (njengemibhoshongo yokupholisa nama-condenser).
