Musimboti weChitofu cheEv PTCInoshandisa hunhu hwePTC positive temperature coefficient thermistor, pamwe chete ne high-voltage power supply system uye thermal management circuit yemota dzemagetsi kuti dzipise. Chaizvoizvo, simba remagetsi rinoshandurwa zvakananga kuita simba rekupisa, uye rozoendeswa kukabhini kana bhatiri kuburikidza nepakati (coolant/air). Rine hunhu hunozvidzora uye hunozvidzora mukati menguva yese, pasina kudiwa kwezvimwe zvishandiso zvakaoma zvekudzora tembiricha, zvichiita kuti ive mhinduro yekupisa inoshanda uye yakachengeteka yemota itsva dzemagetsi.
Maitiro ese akakamurwa kuita zvikamu zviviri: nheyo dzezvinhu zvepakati uye mafambiro chaiwo ekushandiswa kwemotokari. Chekupedzisira chinogona kusiyana zvishoma zvichienderana nemamiriro ekushandiswa (kupisa kwekabhini/kupisa bhatiri). Chinhu chikuru chekushandisa mota ndechemahita ePTC anotonhorera nemvura(kuchinjana kwekupisa kunotonhodza), nepo huwandu hushoma hwekupisa mukamuri huchishandisa mahita ePTC anodziya nemhepo (kuchinjana kwekupisa nemhepo zvakananga). Zvinotevera zvinotsanangurwa zvakateerana:
1, Basic core: Kupisa uye kuzvidzikisira tembiricha musimboti wePTC thermistor
Chinhu chikuru chekupisa chePTC hitaiPTC ceramic sheet (barium titanate based semiconductor ceramic doped with trace rare earth elements), inova ndiyo mudzi wehunhu hwayo hwese:
Kupisa: PTC ceramic chips dzinogadzira nzira dzinofambisa mhepo dzine tambo dzemukati dzinofambisa mhepo dzine voltage yakayerwa (high voltage DC yekushandisa mota, senge 300V+/400V+), dzichigadzira Joule heat kana magetsi achipfuura, zvichiita kuti simba remagetsi rishandurwe zvakananga kuita simba rekupisa nekupisa kwakanyanya (pedyo ne100%, hapana kurasikirwa kwesimba rekushandura);
Tembiricha inodzikamisa yega (hunhu hwepakati): Kana tembiricha yemachipisi ePTC ceramic isingasvike patembiricha yeCurie (tembiricha yakakosha yezvinhu, kazhinji 120-180 ℃ yekushandiswa kwemotokari), kukosha kwekudzivirira kudiki kwazvo, uye kupisa kwakawanda kunoramba kuripo uye kupisa kwakasimba kunoitika, zvichiita kuti tembiricha ikwire nekukurumidza;
Kana tembiricha yadarika tembiricha yeCurie, nzira yemukati inofambisa magetsi ichakurumidza kupwanyika, uye resistance ichawedzera zvakanyanya (kusvika 10 ³~ 10 ⁶ times resistance patembiricha yemumba). Zvinoenderana nemutemo waOhm (P=U ²/R), pasi pemagetsi asingachinji, simba rekudziisa richadzikira zvakanyanya, uye mwero wekudziisa uchadzikira pane mwero wekudziisa kupisa. Tembiricha ichagadzikana zviri nyore pedyo netembiricha yeCurie uye haizorambi ichikwira, zvichidzivirira kupisa kwakaoma uye kupisa zvakanyanya kubva pamudzi;
Kuzvigadzirisa: Kana tembiricha yadzikira pasi petembiricha yeCurie nekuda kwekupiswa kwekupisa (senge kutonhora/kuyerera kwemhepo), kudzvinyirirwa kunokurumidza kudzika kusvika padanho rekudzivirira kushoma, kutangazve kupisa nesimba rakawanda, uye kuwana simba rekudzivirira kupisa rinozvidzora.
2、 Mhinduro huru yekushandisa mota: Maitiro ekushanda kwePTC heater inotonhorera mumvura (yepasi rose yekupisa cabin/bhatiri)
Mota dzinopfuura 90% dzemagetsi dzinoshandisa maheater ePTC anotonhorera ane simba guru (compact structure, yunifomu heat exchange, yakakodzera cabin air circuit uye bhatiri temperature control circuit), zvakabatanidzwa mu coolant circuit circuit yemota itsva dzine simba. Kudziisa cabin nebhatiri kunongowanikwa nekuchinjana pakati pemacircuit akasiyana ePTC heating system imwe chete. Maitiro epakati akafanana, akakamurwa kuita matanho mana:
Kutanga kwemagetsi: Mota VCU (Vehicle Control Unit) inotumira chiratidzo chekutanga kuPTC heater zvichibva pamurairo wemhepo inotonhodza/chiratidzo che sensor yekupisa kwebhatiri (kana bhatiri richida kudziiswa pasi pe5 ℃), uye panguva imwe chete inobatanidza dunhu remagetsi rebhatiri remotokari rine voltage yepamusoro. Simba reDC rine voltage yepamusoro rinoiswa muPTC heating element;
Kuchinja magetsi kubva pakupisa: Maplate ePTC ceramic anokurumidza kuburitsa kupisa pasi pemagetsi akakwira, kusvika pakupisa kwekushanda mukati memasekonzi, uye kupisa kunoendeswa kuimba yekurasa kupisa/chubhu yekuchinjisa kupisa yePTC heater;
Kuchinjana Kwekupisa Kwemuchina Unotonhodza: Pombi yemvura yemagetsi yemuchina unochengetedza kupisa kwemotokari inofambisa chinotonhodza kuti chitenderere mumachubhu ekuchinjana kupisa ePTC heater. Mushure mekunwa kupisa kubva kuPTC heating element, chinotonhodza chinova chinotonhodza chekupisa kwepamusoro (kazhinji 40-60 ℃, chinogadziriswa zvichienderana nekudiwa);
Kutamisirwa kwekupisa
Kudziisa mukamuri: Chinotonhodza chekupisa kwakanyanya chinoyerera chichipinda mukati memhepo inodziya iri mukati memotokari, uye chinofefetera chemhepo inotonhodza yemotokari chinosunda mhepo inotonhora nepakati pemhepo inodziya. Mhepo inotonhora inotora kupisa kwechinhu chinotonhodza uye inova mhepo inopisa, iyo inotumirwa mumotokari kuburikidza nemhepo inobuda kuti iite kuti kabhini idziye;
Kupisa bhatiri: Chinotonhodza chekupisa kwakanyanya chinoyerera zvakananga muplate inotonhorera mvura/heat exchange circuit yebhatiri remagetsi, uye chinopisa bhatiri zvakafanana kuburikidza nekupisa, zvichikwidza tembiricha yebhatiri kusvika padanho rakakodzera rekuchaja nekuburitsa (kazhinji 10-35 ℃), kugadzirisa matambudziko ekudzikira kwekupisa uye kushaja nekuburitsa zvishoma.
Kuwedzera: Mushure mekunge chinhu chinotonhodza chapedza kuchinjana kwekupisa, tembiricha inoderera yozodzokera kuPTC heater kuburikidza nepaipi kuti itore kupisa zvakare, zvichiita kuti pave nedenderedzwa rakavharwa uye nguva dzose ichidziisa; Kana kabhini/bhatiri rasvika patembiricha yakatarwa, VCU inobvisa simba rePTC rine voltage yepamusoro uye inomisa kudziyisa.
3, Mhinduro diki: Kufamba kwemhepo inopisa PTC heater (inoshandiswa chete pakudziyisa kabhini zvishoma)
Kudziisa kwemukamuri kwemamwe mota dzemagetsi madiki uye mamodheru emhando yepamusoro zvinoshandisa maheater ePTC anotonhorera nemhepo (asina kuchinjana kupisa kunotonhorera, anopisa mhepo zvakananga), nechimiro chiri nyore uye maitiro makuru e:
Chinhu chinodziya chePTC ceramic chinopa simba rekupisa rinokwira zvakanyanya;
Chinofefetera mhepo inotonhorera chinofuridza mhepo inotonhora pamusoro pechinhu chinodziya chePTC, uye mhepo inotonhora inochinjana kupisa zvakananga neplate yeceramic yePTC inodziya zvakanyanya, yova mhepo inopisa;
Mhepo inopisa inotumirwa zvakananga mukamuri kuburikidza nemuchina wemhepo kuti iite kuti kupisa kuwedzere.
Zvakashata: Kutamiswa kwekupisa kusina kuenzana, mhepo inopisa yemuno, uye chinhu chinodziya chePTC zvinobata mhepo zvakananga, zvichida guruva rakawanda uye kudzivirira mvura. Nokudaro, zvinongoshandiswa chete kumamota madiki asingadhuri, uye kutonhora kwemvura kunoshandiswa kumota itsva dzine simba repakati kusvika repamusoro.
