Nekuti injini dzemotokari dzemagetsi dzakasanganiswa uye mota dzemagetsi dzinoda kumhanya nguva zhinji munzvimbo yepamusoro inoshanda, kana injini isingagone kushandiswa senzvimbo yekupisa pasi peiyo yakachena yemagetsi drive, mota haizove neinopisa.Kunyanya kune iyo tembiricha mutemo we cab, mamwe ekuwedzera ekupisa anodiwa kuti ave nechokwadi chekunyaradza uye kuchengeteka.Kuti uwedzere huwandu hwekutyaira kwemagetsi dhiraivha uye nekuvandudza kushanda kwemafuta, zvinodikanwa kugadzira kupisa nekukurumidza, zvinobudirira uye zvakachengeteka nekushomeka kwesimba rekushandisa kwebhatiri rekudhonza.Kambani yedu yakagadzira mhando nyowani yeakakwira-voltage heater zvichibva pane itsva thermosphere tekinoroji.
1 Basa uye chinangwa chekudziya kwemotokari
Cab kupisa ibasa rakakosha kuona kutyaira kwakachengeteka uye kwakagadzikana kwemotokari.Pamusoro pekunyaradza kwekabhu uye tembiricha mukati memotokari, iyo air conditioning system (HVAC) inofanirwawo kuve nechokwadi chemamwe mabasa anosanganisira kusangana nezvinodiwa zvemitemo.Semuenzaniso, maererano neEuropean Regulation 672/2010 uye US Federal Motor Vehicle Safety Standard FMVSS103, inopfuura 80% yechando pamhepo inofanira kubviswa mushure memaminitsi makumi maviri.Defrosting uye dehumidification mamwe maviri mabasa anodiwa nemitemo nemirairo.Yakanaka tembiricha kudzorwa kwekabhu ndiyo hwaro hwekunyaradza uye chengetedzo, iriwo chinhu chakakosha kuve nechokwadi chekuti kutyaira hakukanganiswe.
2 Performance index
Izvo zvinonyanya kudiwa kune hita zvinoenderana nekushandiswa kwemotokari.Zvinhu zvinotevera zvinopfupikiswa:
(1) Kunyanya kushanda zvakanaka;
(2) Mutengo wakaderera kana une musoro;
(3) Yekukurumidza kuita nguva uye yakanaka controllability;
(4) Saizi yepasuru ichaderedzwa uye huremu huchareruka;
(5) Kuvimbika kwakanaka;
(6) Kuchengetedza kwakanaka uye kuchengetedza kwezvakatipoteredza.
3 Kupisa pfungwa
Kazhinji, iyo pfungwa yekupisa inogona kukamurwa kuita yekutanga kupisa sosi uye yechipiri kupisa sosi.Nzvimbo huru yekupisa ndiyo sosi yekupisa iyo inogona kuburitsa inodarika 2kW yekupisa inodiwa pakudzora tembiricha yekabhu.Kupisa kunogadzirwa nechipiri kupisa sosi iri pazasi 2kW, iyo inowanzo endeswa kune dzakananga zvikamu, senge zvigaro zvinopisa.
4 Air heater uye mvura yekudziya system
Iyo yekudziya system inogona kukamurwa kuita mapoka maviri makuru, ayo anoenderana nekudziya kunoitwa nemafuta ekudziya kana magetsi emagetsi:
(1) Mhepo inopisa inopisa zvakananga mhepo, iyo inogona kukurumidza kusimudza tembiricha yekombi;
(2) Maheater emvura anoshandisa chinotonhodza semutakuri wekupisa wepakati anogona kugovera kupisa zvirinani uye kubatanidza muHVAC.
Munguva yakapfuura, mafuta anopisa mafuta akaiswa mumagetsi emagetsi emagetsi emagetsi uye motokari dzemagetsi, dzine simba shoma rekushandisa rinogona kuita simba remagetsi rinoshandiswa pakufambisa motokari, pane kupisa.Nekuti kushandisa maheater emagetsi munguva yechando kuchapfupisa huwandu hwekutyaira kwemagetsi ne50%, vanhu vanowanzo sarudza nzira yekupisa mafuta.
5 Magetsi hita pfungwa
Pamberi pekuvandudzwa, akati wandei aripo uye anogona kuve matekinoroji, akadai sewaya ronda kuramba kana yakanaka tembiricha coefficient (PTC) kudziyisa, akaongororwa.Zvinangwa zvina zvikuru zvebudiriro zvakaongororwa uye akati wandei matekinoroji akaenzaniswa achipesana neizvi zvinangwa:
(1) Panyaya yekushanda, hita itsva inofanira kushanda zvakanaka, uye inofanira kukwanisa kupa kupisa kunodiwa kunobuda mukati mehupamhi hwakasiyana-siyana hwekutonhora kwemhepo uye pasi pemagetsi ose;
(2) Panyaya yemhando uye saizi, hita itsva inofanira kunge idiki uye yakareruka sezvinobvira;
(3) Panyaya yekushandisa uye mutengo, kushandiswa kwezvinhu zvisingawanzo pasi uye Pb kunofanirwa kudziviswa, uye mutengo wezvigadzirwa zvitsva unofanirwa kukwikwidza;
(4) Panyaya yekuchengetedzwa, chero njodzi yemagetsi kana njodzi yekupisa inofanira kudzivirirwa pasi pemamiriro ese.
Mune pfungwa iripo yemagetsi hita yemotokari, inonyanya kufarirwa ndeye PTC heater inoshandisa resistor yakagadzirwa nebarium titanate (BaTiO3) ine yakanaka tembiricha coefficient.Nechikonzero ichi, akati wandei maratidziro emusimboti wayo wekushanda anotsanangurwa uye kuenzaniswa neyakaiswa heater yakagadzirwa zvinoenderana neiyohigh-voltage hita HVH.
PTC zvinhu zvine hunhu hwakajeka husina mutsara.Kupokana kunoderera pane tembiricha yakaderera, uyezve inowedzera zvakanyanya kana tembiricha ichikwira.Hunhu uhu hunokonzeresa kuzvimisikidza kwezvino kana voltage yaiswa.
Hebei Nanfeng Automobile Equipment Group Co., Ltd. inogona kugadzira 1.2kw-32kwhigh-voltage electric heaters (HVCH, PTC HEATER)nehunyanzvi hutsva hwekuzadzisa zvinodiwa nemotokari dzakasiyana siyana.
