Sisitemu yo gushyushya ibinyabiziga ikoresheje lisansi
Mbere na mbere, reka turebere hamwe aho ubushyuhe bw'imodoka ikoresha lisansi buturuka.
Ubushobozi bw'ubushyuhe bwa moteri y'imodoka buri hasi cyane, hafi 30%-40% by'ingufu zikomoka ku gutwika ni zo zihinduka ingufu za mekanike z'imodoka, naho izindi zigakurwaho n'icyuma gikonjesha n'imyuka isohora umwuka. Ingufu z'ubushyuhe zikurwaho n'icyuma gikonjesha zigira hafi 25-30% by'ubushyuhe buturuka ku gutwika.
Sisitemu yo gushyushya imodoka isanzwe ikoresha lisansi ni ukuyobora icyuma gikonjesha kiri muri sisitemu yo gukonjesha moteri ku cyuma gihindura ubushyuhe bw'umwuka/amazi kiri muri kabine. Iyo umuyaga unyuze muri radiator, amazi afite ubushyuhe bwinshi ashobora kohereza ubushyuhe mu kirere byoroshye, bityo agahuha. Umuyaga winjira muri kabine ni umwuka ushyushye.
Sisitemu nshya yo gushyushya ingufu
Iyo utekereje ku binyabiziga bikoresha amashanyarazi, bishobora korohera buri wese gutekereza ko sisitemu y'ubushyuhe ikoresha insinga zirwanya umuyaga mu gushyushya umwuka idahagije. Mu by'ukuri, birashoboka rwose, ariko nta sisitemu z'ubushyuhe zirwanya amashanyarazi zibaho ku binyabiziga bikoresha amashanyarazi. Impamvu ni uko insinga zirwanya amashanyarazi zikoresha amashanyarazi menshi cyane.
Muri iki gihe, ibyiciro by'ibishyasisitemu zo gushyushya ingufuahanini ni ibyiciro bibiri, kimwe ni ugushyushya PTC, ikindi ni ikoranabuhanga rya pompe y'ubushyuhe, naho gushyushya PTC bigabanyijemo ibicePTC y'umwuka n'icyuma gikonjesha PTC.
Ihame ryo gushyushya rya sisitemu yo gushyushya ya PTC thermistor ryoroshye kandi ryoroshye kumva. Risa n'isitemu yo gushyushya insinga zirwanya ubushyuhe, ishingiye ku muyoboro w'amashanyarazi kugira ngo itange ubushyuhe binyuze mu muyoboro w'amashanyarazi. Itandukaniro ryonyine ni ibikoresho bya resistance. Insinga zirwanya ubushyuhe ni insinga isanzwe y'icyuma irwanya ubushyuhe bwinshi, kandi PTC ikoreshwa mu modoka z'amashanyarazi zidafite ubushyuhe ni semiconductor thermistor. PTC ni impfunyapfunyo ya Positive Temperature Coefficient. Agaciro k'ubushyuhe na ko kaziyongera. Iki kimenyetso kigaragaza ko iyo umuriro w'amashanyarazi uhoraho, icyuma gishyushya PTC gishyuha vuba iyo ubushyuhe buri hasi, kandi iyo ubushyuhe buzamutse, agaciro k'ubushyuhe kaba kanini, umuyoboro w'amashanyarazi uba muto, kandi PTC ikoresha ingufu nke. Gukomeza ubushyuhe buringaniye bizazigama amashanyarazi ugereranije n'insinga zirwanya ubushyuhe.
Izi nyungu za PTC ni zo zakoreshejwe cyane n'imodoka zikoresha amashanyarazi (cyane cyane izo mu bwoko bworoshye).
Gushyushya PTC bigabanyijemo ibiceIgishyushya gikonjesha cya PTC n'igishyushya cy'umwuka.
Igishyushya amazi cya PTCakenshi bihuzwa n'amazi akonjesha ya moteri. Iyo ibinyabiziga bikoresha amashanyarazi bikorana na moteri ikora, moteri nayo irashyuha. Muri ubu buryo, sisitemu yo gushyushya ishobora gukoresha igice cya moteri kugira ngo ishyushye mbere yo kuyikoresha, kandi ishobora no kuzigama amashanyarazi. Ifoto iri hepfo niIgishyushya gikonjesha gifite ingufu nyinshi za EV.
Nyuma yaPTC yo gushyushya amaziishyushya icyuma gikonjesha, icyuma gikonjesha kizanyura mu gice cy'ubushyuhe kiri mu kabati, hanyuma kikamera nk'uburyo bwo gushyushya bw'imodoka ikoresha lisansi, kandi umwuka uri mu kabati uzazenguruka kandi ugashyuha bitewe n'igikoresho cy'umwuka uhumeka.
ItsindaPTC yo gushyushya umwukani ugushyira PTC ku gice cy'imbere cy'icyuma gishyushya amazi, kuzenguruka umwuka uri mu modoka unyuze mu cyuma gishyushya amazi no gushyushya umwuka uri mu cyuma gishyushya amazi unyuze mu cyuma gishyushya amazi. Imiterere yayo ni yoroshye, ariko irahenze kurusha PTC ishyushya amazi.
