1.Electric Vehicle Thermal Management Zvinodiwa(HVCH)
The passenger compartment ndiyo nzvimbo yezvakatipoteredza inogara mutyairi apo motokari iri kumhanya.Kuti uve nechokwadi chenzvimbo yekutyaira yakagadzika yemutyairi, iyo inodziya manejimendi yekamuri yevatyairi inoda kudzora tembiricha, hunyoro, uye tembiricha yekupa mweya yemukati memotokari nharaunda.Izvo zvinodikanwa zvekutonga kwemafuta ekamuri yevatyairi pasi pemamiriro akasiyana zvinoratidzwa muTafura 1.
Simba bhatiri tembiricha yekudzora chinhu chakakosha chinodiwa kuti uve nechokwadi chekushanda kwakanaka uye kwakachengeteka kwemotokari dzemagetsi.Kana tembiricha yanyanya kukwira, zvinokonzeresa kubuda kwemvura uye kupisa kwega, izvo zvinokanganisa kuchengetedza kwekutyaira;kana tembiricha yakadzikira, bhatiri rinochaja uye simba rekuburitsa rinozodzikiswa kune imwe nhanho.Nekuda kwehuremu hwayo hwepamusoro uye huremu huremu, mabhatiri e-lithium ave mabhatiri emagetsi anoshandiswa zvakanyanya kumotokari dzemagetsi.Izvo zvinodiwa zvekudzivirira kwekushisa kwemabhatiri e-lithium uye bhatiri kupisa mutoro pasi pemamiriro akasiyana-siyana anofungidzirwa maererano nezvinyorwa zvinoratidzwa muTebhu 2. Nekuwedzera zvishoma nezvishoma musimba remagetsi emagetsi emagetsi, kuwedzera kwekushisa kwenzvimbo yekushanda, uye kuwedzera kwekukurumidza kuchaja kumhanya, kukosha kwesimba rekudzora tembiricha yebhatiri mune thermal manejimendi system yave yakakurumbira, kwete chete kusangana nemamiriro akasiyana emigwagwa uye nzira dzakasiyana dzekuchaja uye yekuburitsa.Iyo tembiricha yekudzora mutoro inoshanduka pasi pemamiriro ekushanda emotokari, kufanana kwenzvimbo yekushisa pakati pemabhatiri mapaketi uye kudzivirira uye kudzora kwekupisa kunopisa kunodawo kuzadzisa zvese zvinodikanwa zvekudzora tembiricha pasi pemamiriro akasiyana ezvakatipoteredza senge kutonhora kwakanyanya, kwakakwira. nzvimbo dzinopisa uye dzine hunyoro hwepamusoro, uye nzvimbo dzinopisa dzezhizha uye dzinotonhora dzechando.need.
2. Danho rekutanga PTC kupisa
Muchikamu chekutanga chekugadzirwa kwemotokari dzemagetsi, iyo yakakosha tekinoroji yakavakirwa pakutsiviwa kwemabhatiri, mota uye mamwe masisitimu emagetsi.zvichibva pakuvandudza zvishoma nezvishoma.Iyo air conditioner yemotokari yemagetsi yakachena uye air conditioner yemotokari yemafuta zvese zvinoziva basa refiriji kuburikidza nemhepo yekumanikidza kutenderera.Musiyano uripo pakati pezviviri ndewekuti air conditioner compressor yemafuta emotokari inotyairwa zvisina kunanga neinjini kuburikidza nebhandi, nepo mota yemagetsi yakachena inoshandisa zvakananga electric drive compressor kutyaira firiji.cycle.Kana mota dzemafuta dzichidziiswa munguva yechando, kupisa kwetsvina kweinjini kunoshandiswa zvakananga kupisa imba yevafambi pasina imwezve yekupisa.Zvisinei, kupisa kwemarara kwemotokari yemotokari yakachena yemagetsi haigoni kuzadzisa zvinodiwa zvekupisa kwechando.Naizvozvo, kupisa kwechando idambudziko iro mota dzemagetsi dzakachena dzinoda kugadzirisa..Positive tembiricha coefficient heater (yakanaka tembiricha coefficient, PTC) inoumbwa nePTC ceramic heat element uye aluminium chubhu (PTC Inotonhorera hita/PTC air heater), iyo ine mabhenefiti ekushomeka kudiki kwekupisa uye kupisa kwakanyanya kwekufambisa, uye inoshandiswa mugadziko remotokari dzemafuta Naizvozvo, mota dzemagetsi dzekutanga dzakashandisa vapor compression refrigeration cycle refrigeration pamwe nePTC kudziyisa kuti iwane kutonga kwekupisa kwekamuri yevatyairi.
2.1 Kushandiswa kwepombi yekupisa tekinoroji muchikamu chechipiri
Mukushandiswa chaiko, mota dzemagetsi dzine kudiwa kukuru kwekupisa simba rekushandisa munguva yechando.Kubva pane thermodynamic point of view, iyo COP yePTC kupisa inogara isingasviki 1, iyo inoita kuti simba rekushandisa rePTC kupisa rive rakakwirira uye chiyero chekushandisa simba chakaderera, icho chinorambidza zvakanyanya mota dzemagetsi.mileage.Iyo tekinoroji yepombi yekupisa inoshandisa vapor compression cycle kuti ishandise yakaderera-giredhi kupisa munzvimbo, uye theoretical COP panguva yekupisa yakakura kupfuura 1. Naizvozvo, kushandisa kupisa pombi system panzvimbo yePTC kunogona kuwedzera huwandu hwekufamba kwemotokari dzemagetsi pasi pekupisa. mamiriro.Nekumwe kuvandudzwa kwesimba uye simba rebhatiri remagetsi, kupisa kwemafuta panguva yekushanda kwebhatiri remagetsi kunowedzerawo zvishoma nezvishoma.Iyo yechinyakare mhepo yekutonhodza chimiro haigone kuzadzisa tembiricha inodiwa yebhatiri remagetsi.Naizvozvo, kutonhora kwemvura kwave nzira huru yekudzora tembiricha yebhatiri.Uyezve, sezvo tembiricha yakasununguka inodiwa nemuviri wemunhu yakafanana netembiricha iyo bhatiri remagetsi rinoshanda zvakajairika, zvinodiwa zvekutonhodza zvekamuri yevatyairi uye bhatiri remagetsi zvinogona kuzadzikiswa nekubatanidza zvinochinjisa zvinopisa zvakafanana mukamuri yekupisa yepombi. system.Kupisa kwebhatiri remagetsi kunotorwa zvisina kunanga neanopisa kupisa uye kutonhora kwechipiri, uye dhigirii yekubatanidza yeiyo thermal management system yemotokari yemagetsi yakagadziridzwa.Kunyangwe iyo dhigirii yekubatanidza yakagadziridzwa, iyo yekudziya manejimendi system panguva ino inongobatanidza kutonhora kwebhatiri nekamuri yevatakuri, uye kupisa kwemarara kwebhatiri uye mota hakuna kunyatso shandiswa.
