1. Choyamba tiyeni tifotokoze kuti njira yoyendetsera kutentha ndi chiyani komanso kuti njira yabwino yoyendetsera kutentha ndi chiyani.
Kuchokera pamalingaliro a wogwiritsa ntchito, ntchito yayikulu ya makina oyendetsera kutentha m'nthawi ya magalimoto amagetsi imawonekera mkati ndi kunja. Mkati mwake ndi kusunga kutentha mkati mwa galimoto kukhala kofunda nthawi yozizira komanso kozizira nthawi yachilimwe, monga kutentha mipando ndi chiwongolero, kapena kuyatsa choziziritsira mpweya pasadakhale, ndi zina zotero. - posintha mwachangu kutentha kwa kabati, zimatenga nthawi yayitali bwanji kuti zifike kutentha komwe kwatchulidwa, mphamvu zomwe zimagwiritsidwa ntchito, ndi momwe Kulinganiza kulili chinsinsi; kunja, ndikofunikira kuonetsetsa kuti batire ili pa kutentha koyenera kugwira ntchito - osati kotentha kwambiri, kungayambitse kutentha koopsa komanso moto; kapena kozizira kwambiri, kutentha kwa batire kukakhala kotsika kwambiri, kutulutsa mphamvu kudzatsekedwa, ndipo mphamvu zomwe zimagwiritsidwa ntchito kwenikweni ndi moyo wa batri. Mtunda watsika kwambiri.
Kusamalira kutentha kudzakhala kofunika kwambiri m'nyengo yozizira, chifukwa kupewa kutentha kwa mpweya kwaganiziridwa mokwanira pakupanga batri, koma m'nyengo yozizira, momwe mungagwiritsire ntchito mphamvu zochepa kuti batri likhale pa kutentha koyenera kugwira ntchito ndiye cholinga chachikulu cha kuyang'anira kutentha.
Zikuoneka kuti njira yoyendetsera kutentha kwa magalimoto amagetsi si njira yoziziritsira mpweya yokha ya magalimoto amafuta, komanso imafunika kuchita zinthu zina mozama pamaziko awa, ndipo iyenera kugwirizanitsidwa ndikukonzedwa bwino pamodzi ndi kapangidwe ka magetsi ndi zamagetsi, mphamvu zamagetsi, makina oletsa mabuleki, ndi zina zotero. Chifukwa chake, pali njira zambiri komanso kukongola kwake.
2. Momwe mungayang'anire kutentha
Njira yachikhalidwe: Kutentha kwa PTC
Mu kapangidwe kachikhalidwe, kuti pakhale gwero la kutentha kwa chipinda cha okwera ndi batire, galimoto yamagetsi idzakhala ndi gawo lina la gwero la kutentha PTC. PTC imatanthauza thermistor yotsika bwino kutentha, kukana ndi kutentha kwa gawoli zimagwirizana bwino. Mwanjira ina, kutentha kozungulira kukachepa, kukana kwa PTC kudzachepanso. Mwanjira imeneyi, pamene mphamvu yamagetsi ipatsidwa mphamvu pa voltage yosasintha, kukana kumakhala kochepa ndipo mphamvu yamagetsi imawonjezeka, ndipo mphamvu yamagetsi imawonjezeka moyenerera, zomwe zimapangitsa kuti kutentha kukhale koyenera.
Pali njira ziwiri zotenthetsera PTC, kutentha madzi (Chotenthetsera choziziritsira cha PTC) ndi kutentha kwa mpweya (Chotenthetsera mpweya cha PTCKusiyana pakati pa ziwirizi ndikuti chotenthetsera ndi chosiyana. Kutenthetsa kwa mapaipi kumagwiritsa ntchito PTC kutentha choziziritsira, kenako kusinthana kutentha ndi radiator; kutentha kwa mpweya kumagwiritsa ntchito mpweya wozizira kusinthana kutentha ndi PTC mwachindunji, ndipo pamapeto pake kumachotsa mpweya wofunda.
3. Njira yopititsira patsogolo ukadaulo wowongolera kutentha
Kodi tingapange bwanji chitukuko mu ukadaulo wotsatira wowongolera kutentha?
Chifukwa chofunikira cha kasamalidwe ka kutentha(HVCH)) ndi kulinganiza kutentha kwa kabati ndi mphamvu ya batri, njira yopangira ukadaulo wowongolera kutentha ikufunikabe kuyang'ana kwambiri pa ukadaulo wa "kulumikiza kutentha". Mwachidule, ndi kuganizira kwathunthu pamlingo wagalimoto ndi momwe zinthu zilili: momwe mungaphatikizire ndikugwiritsa ntchito kulumikizana kwa mphamvu, Kuphatikiza: kugwiritsa ntchito mphamvu zamagetsi, ndi kusamutsa mphamvu kumalo ofunikira kudzera mu kuphatikiza kapangidwe ka zigawo zamakina ndi kulamulira kophatikizana kwa malo olumikizirana; kuphatikiza apo, kulamulira kwanzeru kutengera kapangidwe kanzeru nakonso n'kotheka.
