Ngenxa yokuthi izinjini zezimoto zikagesi eziyingxubevange kanye nezimoto zikagesi zidinga ukugijima njalo endaweni esebenza kahle kakhulu, lapho injini ingakwazi ukusetshenziswa njengomthombo wokushisa ngaphansi kwedrayivu kagesi ehlanzekile, imoto ngeke ibe nomthombo wokushisa.Ikakhulukazi ekulawuleni izinga lokushisa kwe-cab, imithombo yokushisa eyengeziwe iyadingeka ukuze kuqinisekiswe induduzo nokuphepha.Ukuze ukhulise ibanga lokushayela likagesi futhi uthuthukise ukusebenza kahle kukaphethiloli, kuyadingeka ukukhiqiza ukushisa ngokushesha, ngempumelelo nangokuphepha ngokusebenzisa amandla amancane ebhethri elidonsayo.Inkampani yethu isungule uhlobo olusha lwe-heater ene-voltage ephezulu esekelwe kubuchwepheshe obusha be-thermosphere.
1 Umsebenzi nenjongo yokushisisa imoto
Ukushisa kwe-cab kuwumsebenzi obalulekile wokuqinisekisa ukushayela okuphephile nokunethezeka kwemoto.Ngaphezu kokunethezeka kwekhebhu nezinga lokushisa ngaphakathi kwemoto, i-air conditioning system (HVAC) kufanele futhi iqinisekise imisebenzi ethile okuhlanganisa ukuhlangabezana nezidingo zokulawula.Isibonelo, ngokuya nge-European Regulation 672/2010 kanye ne-US Federal Motor Vehicle Safety Standard FMVSS103, ngaphezu kuka-80% weqhwa kuwindshield kufanele asuswe ngemva kwemizuzu engu-20.Ukucwiliswa kweqhwa kanye nokususa umswakama yiminye imisebenzi emibili edingwa yimithetho neziqondiso.Ukulawulwa okuhle kwezinga lokushisa kwe-cab kuyisisekelo sokunethezeka nokuphepha, okubuye kube yisici esibalulekile sokuqinisekisa ukuthi ukushayela akuthinteki.
2 Inkomba yokusebenza
Izidingo eziyinhloko ze-heater zincike ekusetshenzisweni kwemoto.Izici ezilandelayo zifinyeziwe:
(1) Ukusebenza kahle kakhulu;
(2) Izindleko eziphansi noma ezifanele;
(3) Isikhathi sokusabela esisheshayo kanye nokulawulwa okuhle;
(4) Usayizi wephakeji uzoncishiswa futhi isisindo sibe lula;
(5) Ukwethembeka okuhle;
(6) Ukusimama okuhle nokuvikelwa kwemvelo.
3 Umqondo wokushisa
Ngokuvamile, umqondo wokushisa ungahlukaniswa ube umthombo wokushisa oyinhloko kanye nomthombo wokushisa wesibili.Umthombo wokushisa oyinhloko umthombo wokushisa ongakhiqiza ngaphezu kuka-2kW wokushisa odingekayo ekulawuleni izinga lokushisa kwekhebhu.Ukushisa okukhiqizwa umthombo wokushisa wesibili kungaphansi kuka-2kW, okuvame ukuqondiswa ezingxenyeni ezithile, njengezifudumezi zezihlalo.
4 I-heater yomoya kanye nesistimu yokufudumeza amanzi
Isistimu yokushisisa ingahlukaniswa ngezigaba ezimbili eziyinhloko, ezincike ekushiseni okutholwa ama-heaters noma ama-heater kagesi:
(1) Isifudumezi somoya sishisa umoya ngokuqondile, esingakhuphula ngokushesha izinga lokushisa lendlu;
(2) Izifudumezi zamanzi ezisebenzisa okokupholisa njengesiphathi sokushisa okuphakathi zingasabalalisa kangcono ukushisa futhi zihlanganiswe ku-HVAC.
Esikhathini esidlule, ama-heater aphethwe uphethiloli afakwa ezimotweni zikagesi eziyingxubevange kanye nezimoto zikagesi, ukusetshenziswa kwazo okuphansi kwamandla kagesi kungenza amandla kagesi asetshenziswe ekushayeleni imoto, kunokufudumeza.Ngenxa yokuthi ukusebenzisa izifudumezi zikagesi ebusika kuzofinyeza ibanga lokushayela ngogesi cishe ngo-50%, ngokuvamile abantu bakhetha indlela yokushisisa uphethiloli.
5 Umqondo we-heater kagesi
Ngaphambi kwentuthuko, ubuchwepheshe obuningana obukhona nobungase bube khona, obufana nokumelana nenxeba lezintambo noma ukushisisa kwe-pozitemperature coefficient (PTC), kwahlaziywa.Izinjongo ezine zentuthuko ezinkulu zahlolwa futhi ubuchwepheshe obuncane obungase buqhathaniswe nalezi zinhloso:
(1) Mayelana nokusebenza kahle, isifudumezi esisha kufanele sisebenze kahle, futhi kufanele sikwazi ukuhlinzeka ngokukhipha ukushisa okudingekayo phakathi kwezinga elibanzi lokushisa lokupholisa kanye nangaphansi kwawo wonke amandla ombane;
(2) Ngokwezinga nosayizi, isifudumezi esisha kufanele sibe sincane futhi sikhanye ngangokunokwenzeka;
(3) Mayelana nokusebenziseka nezindleko, ukusetshenziswa kwezinto ezingavamile zomhlaba kanye ne-Pb kufanele kugwenywe, futhi izindleko zemikhiqizo emisha kufanele zincintisane;
(4) Ngokokuphepha, noma iyiphi ingozi yokushaqeka kukagesi noma ingozi yokushisa kufanele igwenywe ngaphansi kwazo zonke izimo.
Emcabangweni okhona we-heater kagesi ezimotweni, edume kakhulu ihitha ye-PTC esebenzisa i-resistor eyenziwe nge-barium titanate (BaTiO3) ene-coefficient yezinga lokushisa elihle.Ngenxa yalesi sizathu, imininingwane eminingana yesimiso sayo sokusebenza iyachazwa futhi iqhathaniswa ne-heater egqinsiwe eyenziwe ngokushohigh-voltage heater HVH.
Izakhi ze-PTC zinezici ezisobala kakhulu ezingaqondile.Ukumelana kunciphisa ekushiseni okuphansi, bese kukhula kakhulu lapho izinga lokushisa likhuphuka.Lesi sici sibangela ukuzikhawula kwamandla wamanje lapho kusetshenziswa i-voltage.
I-Hebei Nanfeng Automobile Equipment Group Co., Ltd. ingakhiqiza i-1.2kw-32kwama-heaters kagesi aphezulu (i-HVCH, i-PTC HEATER)ngobuchwepheshe obusha bokuhlangabezana nezidingo zezimoto ezahlukene.
