Makina otenthetsera magalimoto amafuta
Choyamba, tiyeni tionenso gwero la kutentha kwa galimoto yamafuta.
Kutentha kwa injini yagalimoto kumakhala kochepa, pafupifupi 30% -40% ya mphamvu yomwe imapangidwa ndi kuyaka imasinthidwa kukhala mphamvu yamakina agalimoto, ndipo ena onse amachotsedwa ndi mpweya woziziritsa komanso wotulutsa.Mphamvu ya kutentha yomwe imachotsedwa ndi zoziziritsa kukhosi zimatengera pafupifupi 25-30% ya kutentha kwa kuyaka.
Makina otenthetsera agalimoto yanthawi zonse amawongolera choziziritsa munjira yozizirira injini kupita ku chotenthetsera mpweya/madzi mu kabati.Mphepo ikamadutsa mu radiator, madzi otentha kwambiri amatha kutumiza kutentha kumlengalenga, motero amawomba Mphepo yomwe imalowa mu kabati ndi mpweya wofunda.
Njira yatsopano yotenthetsera mphamvu
Mukamaganizira za magalimoto amagetsi, zingakhale zophweka kuti aliyense aganize kuti makina otenthetsera omwe amagwiritsira ntchito mwachindunji waya wotsutsa kutentha mpweya sakwanira.Mwachidziwitso, ndizotheka kwathunthu, koma pali pafupifupi palibe makina opangira magetsi opangira magetsi.Chifukwa chake ndi chakuti waya wotsutsa amadya magetsi ambiri..
Pakali pano, magulu atsopanomachitidwe otenthetsera mphamvumakamaka magulu awiri, imodzi ndi Kutentha kwa PTC, inayo ndi ukadaulo wa kupopera kutentha, ndipo Kutentha kwa PTC kumagawidwampweya PTC ndi ozizira PTC.
Mfundo yotenthetsera ya mtundu wa PTC thermistor ndi yosavuta kumva.Ndizofanana ndi makina otenthetsera waya wotsutsa, omwe amadalira pakali pano kuti apange kutentha kupyolera mu kukana.Kusiyana kokha ndi zinthu za kukana.Waya wokaniza ndi waya wachitsulo wosasunthika kwambiri, ndipo PTC yomwe imagwiritsidwa ntchito pamagalimoto oyera amagetsi ndi semiconductor thermistor.PTC ndiye chidule cha Positive Temperature Coefficient.Mtengo wotsutsa udzawonjezekanso.Chikhalidwe ichi chimatsimikizira kuti pansi pa chikhalidwe cha voteji nthawi zonse, chowotcha cha PTC chimatentha mofulumira pamene kutentha kuli kochepa, ndipo pamene kutentha kumakwera, mtengo wotsutsa umakhala waukulu, wamakono umakhala wocheperako, ndipo PTC imagwiritsa ntchito mphamvu zochepa.Kusunga kutentha kosasintha kumapulumutsa magetsi kuyerekeza ndi kutentha kwa waya.
Ndizo zabwino za PTC zomwe zakhala zikugwiritsidwa ntchito kwambiri ndi magalimoto amagetsi oyera (makamaka zitsanzo zotsika).
Kutentha kwa PTC kumagawidwaChowotcha chozizira cha PTC ndi chowotcha mpweya.
PTC chotenthetsera madzinthawi zambiri amaphatikizidwa ndi madzi ozizira agalimoto.Pamene magalimoto amagetsi akuyenda ndi injini ikuyenda, galimotoyo imatenthedwanso.Mwa njira iyi, makina otenthetsera amatha kugwiritsa ntchito gawo la injini kuti ayambe kutentha pamene akuyendetsa galimoto, komanso amatha kusunga magetsi.EV high voltage coolant heater.
Pambuyo paKutentha kwa madzi PTCKutenthetsa kozizira, koziziritsira kumadutsa pakati pa kutentha mu cab, ndiyeno kumakhala kofanana ndi kutenthetsa kwa galimoto yamafuta, ndipo mpweya mu cab udzayendetsedwa ndikuwotchedwa pansi pa chowombera.
TheKutentha kwa mpweya PTCndi kukhazikitsa PTC mwachindunji pa heater pachimake cha kabati, amazungulira mpweya m'galimoto kudzera blower ndi mwachindunji kutentha mpweya mu kabati kudzera PTC chotenthetsera.Mapangidwewo ndi osavuta, koma ndi okwera mtengo kuposa PTC yotenthetsera madzi.
