3 Zitsanzo za kusamutsa kutentha pogwiritsa ntchito convection
1. Fotokozani pogwiritsa ntchito zitsanzo, tanthauzo lake kusamutsa kutentha pogwiritsa ntchito convection ?
Zokambirana
Kusamutsa kutentha kwa convection ndi kusamutsa kutentha komwe kumayenderana ndi kuyenda kwa zinthu. Mwachitsanzo, taganizirani madzi omwe ali mu chidebe cha aluminiyamu akutenthedwa pa chitofu. Poyamba, kutentha kumasamutsidwa ndi conduction ndi radiation kuchokera ku lawi kupita ku chidebe cha aluminiyamu, kenako ndi conduction kuchokera ku chidebe cha aluminiyamu kupita ku madzi.
Kusamutsa kutentha kwa convection kumayamba pamene madzi pafupi ndi chidebe cha aluminiyamu amalandira kutentha kowonjezera, kuonjezera kutentha kwake kenako n’kukula. Kukula kumeneku kumachepetsa kuchuluka kwake, zomwe zimapangitsa kuti madzi ayandama pamwamba. Madzi amenewa amalowedwa m’malo ndi madzi ndi kutentha kochepa komanso kuchuluka kwakukulu. Njirayi imapitirira mosalekeza, ndikupanga mphamvu ya convection mkati mwa chidebecho. Njirayi imasiya madzi onse akafika pamwamba. kutentha chomwecho kapena pamene madzi akuwira.
Chitsanzo china ndi mphepo. Mphepo ndi mpweya womwe ukuyenda. Mpweya umayenda kotero kuti kutentha kumatha kusuntha kuchokera kumadera otentha kwambiri kupita kumadera otentha pang'ono.
2. Kodi n'zotheka kuti kutentha kusamutsidwa ndi convection kuchitika pakati pa maatomu/mamolekyulu a zinthu zolimba?

Kusamutsa kutentha kwa convection ndi kusamutsa kutentha komwe kumayenderana ndi kuyenda kwa zinthu, mwachitsanzo, kuyenda kwa mpweya ndi madzi a m'nyanja. Mpweya woyenda umatchedwa mphepo. Mpweya ukayenda, kutentha kumayendanso nawo.
Kusamutsa kutentha kudzera mu convection kumachitika kokha mu zinthu zomwe zimatha kuyenda, zomwe zimadziwika kuti madzi. Zinthu zomwe zimatha kuyenda ndi zamadzimadzi ndi mpweya, pomwe zinthu zolimba sizingathe kuyenda.
3. Kusamutsa kutentha kudzera mu convection kungachitike mwachilengedwe kapena mwa kupanga. Lembani ndi kufotokoza zitsanzo zina!

Zitsanzo za kusamutsa kutentha kudzera mu convection zomwe zimachitika mwachilengedwe ndi njira yopangira mphepo (monga mphepo yapamtunda ndi mphepo ya m'nyanja), njira yopangira madzi otentha, utsi wochokera ku moto womwe nthawi zonse umapita mmwamba, ndi zina zotero.
Zitsanzo za kusamutsa kutentha kwa convection kopangidwa ndi anthu ndi kusamutsa utsi kudzera m'ma chimney, kusamutsa madzi muzipangizo zoperekera madzi otentha, zopukutira tsitsi, ndi zina zotero.
