Iipakethi zebhetri ezilungiselelweyo zinesantya esazo sokutshaja nokukhupha, nto leyo evelisa ubushushu obuthile ngokwendalo. Ukufudumala okuncinci kulungile, kodwa kakhulu kunokuba yingxaki. Amaqondo obushushu okusingqongileyo nawo anendima – iimeko ezishushu zinokuba yingozi, ngelixa ezibandayo zinciphisa ukusebenza kakuhle.
Yingakho ulawulo lwe-thermal lubalulekile ekuyileni ezi zixhobo zebhetri; iqinisekisa ukusebenza kakuhle ngokugcina ubushushu obufanelekileyo kunye nokuthintela ukufudumala okanye ukugqithisa ngexesha lokusetyenziswa kunye nokutshaja.
Yintoni uLawulo lweThermal?
Ulawulo lwe-Thermal yinkqubo egcina inkqubo ngaphakathi kweqondo lokushisa lokusebenza.
Kwizixhobo zombane, inceda ukukhupha ubushushu obugqithisileyo ukuthintela ubushushu. Kuba uninzi lweenkqubo zivelisa ubushushu, kukho umngcipheko wokonakalisa izinto ezibuthathaka ukuba ubushushu buqokelelana kakhulu. Ngaphezu koko, ubushushu obugqithisileyo bangaphandle bunokuphazamisana nombane.
Iinjineli zisebenzisa izisombululo zolawulo lobushushu kuwo wonke amashishini ahlukeneyo, anje nge-aerospace, iimoto, iibhetri, kunye namaziko edatha. Ukugcina amaqondo obushushu afanelekileyo kubalulekile kuyilo kuba konyusa ukusebenza kunye nokuqina.
Ukulawula ubushushu, bahlala bexhomekeke kwizixhobo ezinje ngeesinki zobushushu kunye neefeni zokupholisa okanye iinkqubo ezipholileyo zolwelo ezinolwelo lwe-cryogenic lokupholisa ngokukhawuleza. Ukongeza, iinjineli ze-thermal zinokusebenzisa izixhobo zokukhusela ukunciphisa ukuhanjiswa kobushushu kwiindawo ezibuthathaka.
Uthini Umahluko phakathi koLawulo oluSebenzayo kunye nolwePassive Thermal?
Iinjineli ziphuhlisa iinkqubo zolawulo lwe-thermal zisebenzisa zombini itekhnoloji esebenzayo kunye ne-passive.
Izinto ezisebenzayo, ezifana neefeni kunye neempompo, zifuna umthombo wamandla wangaphandle, ngelixa izinto ezisebenzayo, ezifana ne-heat sinks kunye nemibhobho, ayenzi.
Itekhnoloji ye-Passive iphucula iinkqubo zendalo ezifana ne-convection, i-convection, okanye i-radiation ngaphakathi kwenkqubo.
Zombini iintlobo zijolise ekuphuculeni ukutshatyalaliswa kobushushu kunye nokugcina ubushushu bokusebenza. Ekubeni izixhobo ezisetyenziswayo azidingi amandla ongezelelweyo, zihlala zilungele uhlahlo lwabiwo-mali kunokhetho olusebenzayo lolawulo lwe-thermal.
Imizekelo yeeNdlela zokuPholisa eziSebenzayo
Ukuhanjiswa ngenkani
Uninzi lwezixhobo zokupholisa ezisebenzayo zisebenzisa iifeni okanye izivutheli ukonyusa umoya ojikeleze iindawo ezishushu, ezinceda ukupholisa izinto. Ngokutyhala umoya oshushu ngokukhawuleza, le ndlela iyayinyusa i-convection kwaye yenza ukukhutshwa kobushushu kusebenze ngakumbi.
Iicoolers ze-Thermoelectric
Izipholileyo ze-Thermoelectric, okanye iimpompo zobushushu eziqinileyo, ziqhelekile xa usebenza neesemiconductors. Zincinci kwaye zixinene, zihlala zifakwe phakathi kwesitya sobushushu kunye nomthombo wobushushu.
Xa usebenzisa i-voltage kubo, benza umahluko wobushushu phakathi kwamacala amabini. Lo msantsa mkhulu wobushushu unceda ukonyusa izinga lokuqhuba.
Imizekelo yeeNdlela zokuPholisa eziPhambili
Ubushushu butshona
Iisinki zobushushu zixhaphakile kwizixhobo zokupholisa ezingenzi nto.
Ngokusisiseko, isitya sobushushu, esenziwe ngentsimbi efana nobhedu okanye i-aluminiyam eqhuba ubushushu kakuhle, incamathela kumthombo wobushushu. Amandla e-thermal ahamba ngentsimbi ngokuqhuba ukusuka kwindawo eshushu kwaye akhululwe emoyeni ojikelezileyo ngokuhambisa kwendalo ukusuka kumphezulu wobushushu.
Izisasazi zobushushu
Izisasazo zobushushu zizixhobo ezithandwayo zokupholisa ezisetyenziswayo ezisebenzisa iifoyile ze-thermal conductive okanye iipleyiti zentsimbi ukusasaza ubushushu obugxininisiweyo kwindawo enkulu. Ngokuqhelekileyo zisebenza njengesixhobo esiphakathi phakathi komthombo wobushushu kunye nabatshintshisi bobushushu besibini.
Ulawulo lweThermal kwiKhemistry yeBattery eyahlukeneyo
Iindidi ezahlukeneyo zeebhetri zisebenza ngcono phakathi kobushushu obuthile. Nantsi inkcazo ekhawulezayo kwintlawulo yabo efanelekileyo kunye namaxesha okukhupha:
- I-Lithium-ion: Intlawulo phakathi kwe-0 ° C kunye ne-45 ° C; Ukukhutshwa ukusuka ku-20°C ukuya kuma-60°C

Le mizekelo inceda abaqulunqi baqonde imida ye-thermal ukuze bakwazi ukudala iinkqubo zokulawula ukushisa, ukuqinisekisa ukuba iipakethi zebhetri zisebenza kakuhle kuzo zonke iintlobo zeemeko.
Kwenzeka ntoni xa iibhetri zingenaLawulo lweThermal
Iibhetri zifudumala ngenxa yokumelana nombane. Njengoko umsinga utyhutyha kwiindawo ezifana nodibaniso kunye ne-electrolytes, yenza ubushushu. Ukuxhathisa okungaphezulu kubangela ubushushu obuninzi, obunokugqoka phantsi izixhobo kunye nokunciphisa umthamo webhetri, ngamanye amaxesha kubangele ukubaleka kwe-thermal.
Ngokuchaseneyo, amaqondo obushushu abandayo athoba i-conductivity, okwenza kube nzima ukuba ii-electron zihambe kunye nokwandisa ukuxhathisa. Oku kunokukhokelela ekusebenzeni kakubi kunye nemiba yokutshaja ngeentlobo ezithile zeebhetri.
Ukuqukumbela
Ukubaleka kwe-Thermal kunye nokuncipha kwemveliso yimiba ephambili yolawulo lobushushu kwiibhetri. Iinkampani ezininzi zifuna iipakethi zebhetri ukuze ziphumelele uvavanyo lwe-thermal lwesiqinisekiso. Ukuqonda isicelo sakho esithile kunye neshishini kunceda ukuyila ipakethi yebhetri ehambelanayo ebonisa ukusebenza okukhuselekileyo.
