Chiyambi cha Plate Fin Heat Exchanger

2024-02-19

Aluminium plate fin heat exchanger nthawi zambiri imakhala ndi magawo, zipsepse, zisindikizo, ndi zopatuka. Zipsepse, zopindika ndi zosindikizira zimayikidwa pakati pa magawo awiri oyandikana kuti apange interlayer, yomwe imatchedwa njira. Ma interlayers oterowo amapakidwa molingana ndi njira zosiyanasiyana zamadzimadzi ndikumangirira muthunthu kuti apange mtolo wa mbale. Mtolo wa mbale ndi mbale. Pachimake cha fin heat exchanger. Plate fin heat exchanger yakhala ikugwiritsidwa ntchito kwambiri mumafuta, mankhwala, kukonza gasi ndi mafakitale ena.

Mawonekedwe a Plate Fin Heat Exchanger

(1) Kutentha kwa kutentha kumakhala kwakukulu. Chifukwa cha kusokonezeka kwa zipsepse zamadzimadzi, malirewo amathyoledwa mosalekeza, motero amakhala ndi coefficient yayikulu yotengera kutentha; pa nthawi yomweyo, chifukwa olekanitsa ndi zipsepse ndi woonda kwambiri ndi madutsidwe mkulu matenthedwe, mbale zipsepse kutentha Exchanger akhoza kukwaniritsa dzuwa mkulu.

(2) yaying'ono, popeza mbale zipsepse kutentha exchanger ali yaitali pamwamba yachiwiri, malo ake enieni pamwamba akhoza kufika 1000㎡/m3.

(3) Zopepuka, chifukwa ndizophatikizana ndipo makamaka zopangidwa ndi aluminium alloy, ndipo tsopano zitsulo, mkuwa, zida zophatikizika, ndi zina zambiri zapangidwanso.

(4) Wamphamvu kusinthasintha, mbale zipsepse kutentha exchanger angagwiritsidwe ntchito: kusinthana kutentha pakati pa madzi osiyanasiyana ndi gawo kusintha kutentha ndi gulu kusintha boma. Kupyolera mu dongosolo ndi kuphatikiza njira zoyendetsera, zimatha kusinthana ndi kutentha kosiyanasiyana monga kuthamanga kwa counter, kuwoloka, kutuluka kwa mitsinje yambiri, ndi kutuluka kwa ma pass-multi-pass. Zofunikira zosinthira kutentha kwa zida zazikuluzikulu zitha kukwaniritsidwa kudzera pakuphatikiza kwa mndandanda, zofananira, ndi zolumikizana zotsatizana pakati pa mayunitsi. M'makampani, amatha kumalizidwa ndikupangidwa mochuluka kuti achepetse ndalama, ndipo kusinthasintha kungathe kukulitsidwa kudzera muzitsulo zomangamanga.

(5) Njira yopangira mbale yopangira kutentha kwa mbale imakhala ndi zofunika kwambiri komanso zovuta.

Mfundo yogwiritsira ntchito mbale fin heat exchanger

Kuchokera pa mfundo yogwiritsira ntchito plate fin heat exchanger, mbale fin heat exchanger idakali ya partitioner wall heat exchanger. Mbali yake yaikulu ndi yakuti mbale fin kutentha exchanger ali yaitali yachiwiri kutentha kutengerapo pamwamba (chipezi), kotero kutentha kutengerapo ndondomeko si ikuchitika pa pulayimale kutentha kutengerapo pamwamba (baffle mbale), komanso pa yachiwiri kutentha kutengerapo pamwamba. khalidwe. Kutentha kwa sing'anga kumbali yotentha kwambiri kumatsanuliridwa mkatikati kumbali ya kutentha kochepa kamodzi, ndipo gawo la kutentha limasamutsidwa motsatira kutalika kwa nsonga, ndiko kuti, motsatira kutalika kwa chipsepse. , pali kugawa kutsanulira kutentha, ndiyeno kutentha ndi convectively anasamutsa kwa otsika kutentha mbali sing'anga. Popeza kutalika kwa zipsepsezo kumaposa makulidwe a zipsepsezo, njira yoyendetsera kutentha motsatira mbali ya kutalika kwake imakhala yofanana ndi ndodo yowonda yowongoka. Panthawiyi, kukana kwa kutentha kwa fin sikungathe kunyalanyazidwa. Kutentha kwakukulu kumalekezero onse a zipsepsezo ndi kofanana ndi kutentha kwa magawano, ndipo ndi kutentha kwa convective kumasulidwa pakati pa Finn ndi sing'anga, kutentha kumapitirirabe kuchepa mpaka kutentha kwapakati pakati pa fin.
