Kodi chotchinga kutentha ndi chiyani?Malamulo ambiri a zida ndi ukadaulo wotchinjiriza mapaipi, zida zotenthetsera zotenthetsera zimatanthawuza kuti kutentha kwapakati kumakhala kofanana kapena kuchepera 623K (350 ° C), kuwongolera kwamafuta kumakhala kosakwana 0. 14W/(mK) zakuthupi.Zipangizo zoyatsira moto nthawi zambiri zimakhala zopepuka, zotayirira, za porous, komanso kutsika kwamafuta.Nthawi zambiri amagwiritsidwa ntchito poletsa kutayika kwa kutentha m'zida zotenthetsera ndi mapaipi, kapena kugwiritsidwa ntchito pozizira (komwe kumatchedwanso kuzizira) komanso kutentha pang'ono (komwe kumatchedwanso cryogenic), kotero kuti zinthu zoteteza kutentha m'dziko langa zimatchedwanso kuteteza kutentha kapena kuzizira.Panthawi imodzimodziyo, chifukwa cha mapangidwe a porous kapena fibrous of thermal insulation material with good sound mayamwidwe ntchito, amagwiritsidwanso ntchito kwambiri mu zomangamanga.

Zida zotetezera kutentha zimakhala ndi zizindikiro zotsatirazi.

(1) Thermal conductivity.Monga zida zopangira matenthedwe, kutentha kwamafuta kuyenera kukhala kochepa momwe kungathekere.Nthawi zambiri, matenthedwe matenthedwe ayenera kukhala osachepera 0.14W/(mK).Monga matenthedwe kutchinjiriza zakuthupi kuteteza kuzizira, kufunikira kwa matenthedwe madutsidwe ndi apamwamba.
(2) Kachulukidwe kachulukidwe, kulemera kosowa kwa zida zotchinjiriza-zambiri kuyenera kukhala kocheperako, nthawi zambiri kutentha kumakhala kochepa, koma nthawi yomweyo mphamvu ya makinawo idzachepetsedwa, kotero kusankha koyenera kuyenera kupangidwa. .
(3) Mphamvu zamakina.Pofuna kupewa kuti zinthu zotchinjiriza kutentha zisawonongeke kapena kuwonongeka chifukwa cha kulemera kwake ndi mphamvu yake, mphamvu yake yopondereza siyenera kukhala yosachepera 3kg/cm.
(4) Kuchuluka kwa madzi.Pambuyo pazitsulo zotentha zotentha zimatenga madzi, sizidzangochepetsa kwambiri ntchito yotentha yamoto, l Ndizovulaza kwambiri zitsulo skimming.Choncho, mpesa ayenera kusankha kutentha-kuteteza zinthu ndi mlingo otsika mayamwidwe madzi.
(5) Kutentha kwa kutentha ndi kutentha kwa ntchito, zipangizo zotetezera kutentha zokhala ndi katundu wotsutsa kutentha ziyenera kusankhidwa malinga ndi kutentha kwa malo ogwiritsira ntchito."Kugwiritsa ntchito kutentha" ndilo maziko a kutentha kwa kutentha kwa zipangizo zotentha.

Zomwe zili pamwambazi ndizofunikanso zokhudzana ndi zomwe zimatchinjiriza kutentha ndi zinthu zodzitchinjiriza zomwe zidayambitsidwa ndi kampani yaukadaulo yoteteza moto.Nkhaniyi ikuchokera ku goldenpower Group
