Ubwino wa PTC Coolant Heaters mu Automotive High Voltage Systems

Pamene ukadaulo wamagalimoto ukupitilira kupita patsogolo, kufunikira kwa makina otenthetsera ogwira ntchito bwino komanso odalirika pamagalimoto amphamvu kwambiri kwakhala kofunika kwambiri. Chotenthetsera choziziritsa kutentha cha PTC (positive temperature coefficient), chomwe chimadziwikanso kuti chotenthetsera choziziritsa kutentha champhamvu chamagalimoto (HVCH), ndi njira yatsopano yomwe ikukula kwambiri mumakampani opanga magalimoto. Mu blog iyi, tifufuza zabwino za ma heaters oziziritsa mpweya a PTC m'magalimoto amphamvu kwambiri komanso chifukwa chake ndi omwe amapanga magalimoto oyamba kusankha.

Kutentha kogwira mtima

Chimodzi mwa zabwino zazikulu zaChotenthetsera choziziritsira cha PTCs ndiye mphamvu yawo yotenthetsera bwino. Ma heater awa adapangidwa kuti azitenthetsa choziziritsira mofulumira m'magalimoto amphamvu kwambiri, kuonetsetsa kuti mkati mwa magalimoto ndi zinthu zofunika kwambiri zimakhalabe kutentha koyenera, makamaka nyengo yozizira. Ukadaulo wa PTC umalola kutentha mwachangu komanso kokhazikika, kupatsa okwera magalimoto mwayi woyendetsa bwino komanso wotetezeka.

Kudalirika ndi kulimba

Ma heater a PTC coolant amadziwika kuti ndi odalirika komanso olimba, zomwe zimapangitsa kuti akhale abwino kwambiri pamagalimoto okhala ndi mphamvu zambiri. Mosiyana ndi makina otenthetsera achikhalidwe, ma heater a PTC sakhala okalamba chifukwa cha mphamvu zawo zodzilamulira okha. Izi zikutanthauza kuti amatha kugwira ntchito bwino kwa nthawi yayitali popanda kufunikira kukonza kapena kusintha pafupipafupi, zomwe pamapeto pake zimachepetsa mtengo wonse wa umwini wa eni magalimoto.

chitetezo ndi ubwino wa chilengedwe

Kuwonjezera pa ntchito yake yotenthetsera, ma heater a PTC coolant amaperekanso chitetezo komanso ubwino pa chilengedwe. Ma heater amenewa adapangidwa kuti azigwira ntchito pamagetsi amphamvu popanda chiopsezo cha kutentha kwambiri, zomwe zimapangitsa kuti akhale chisankho chotetezeka komanso chodalirika pamagalimoto amphamvu kwambiri. Kuphatikiza apo, ma heater a PTC ndi abwino kwa chilengedwe chifukwa sadalira mafuta oyaka kuti atenthetse, zomwe zimachepetsa mpweya woipa womwe umalowa m'galimoto komanso zimathandiza kupanga malo oyera komanso obiriwira.

Kusinthasintha ndi kuphatikiza

Ma heater a PTC coolant ndi osinthasintha ndipo amatha kuphatikizidwa mosavuta m'magalimoto osiyanasiyana amphamvu kwambiri. Kaya ndi galimoto yosakanikirana, yamagetsi kapena yamagetsi, ma heater a PTC amatha kusinthidwa kuti akwaniritse zofunikira pakutenthetsa pamapulatifomu osiyanasiyana agalimoto. Kukula kwake kochepa komanso njira zokhazikika zokhazikika zimapangitsa kuti ikhale yoyenera pamapangidwe amakono agalimoto, zomwe zimapangitsa kuti ikhale yogwirizana bwino popanda kusokoneza magwiridwe antchito.

kugwiritsa ntchito mphamvu moyenera

Kugwiritsa ntchito bwino mphamvu ndi chinthu chofunikira kwambiri pamagalimoto amphamvu kwambiri, ndipo ma heater a PTC coolant ndi abwino kwambiri pankhaniyi. Ma heater amenewa adapangidwa kuti asinthe mphamvu zamagetsi kukhala kutentha kwambiri, kuchepetsa kuwononga mphamvu ndikuwonjezera kugwiritsa ntchito bwino kutentha. Izi sizimangothandiza kuchepetsa kugwiritsa ntchito mphamvu zonse za galimoto, komanso zimathandiza kukulitsa kuchuluka kwa magalimoto amagetsi, zomwe zimapangitsa kuti azikhala oyenera kugwiritsidwa ntchito tsiku ndi tsiku.

Pomaliza

Powombetsa mkota,Chotenthetsera choziziritsira cha EVMa s akhala osintha kwambiri machitidwe a magalimoto amphamvu kwambiri, omwe amapereka zabwino zambiri monga kutentha bwino, kudalirika, chitetezo, ubwino wa chilengedwe, kusinthasintha, kuphatikiza komanso kugwiritsa ntchito bwino mphamvu. Pamene makampani opanga magalimoto akupitiliza kugwiritsa ntchito magetsi ndi ukadaulo wamagetsi amphamvu kwambiri, ma heater a PTC coolant adzachita gawo lofunika kwambiri pakupanga tsogolo la makina otenthetsera magalimoto. Ndi mbiri yawo yotsimikizika komanso zabwino zambiri, sizosadabwitsa kuti ma heater a PTC coolant ndi chisankho choyamba cha opanga magalimoto omwe akufuna kukonza magwiridwe antchito ndi kukhazikika kwa magalimoto awo amphamvu kwambiri.
