Cov yam ntxwv ntawm extruded aluminium finned raj

Cov yam ntxwv ntawm cov extruded aluminium finned raj yog tias nws txais yuav daim ntawv ntawm lub hauv paus raj lub tes tsho aluminium raj. (Lub hauv paus raj tuaj yeem ua los ntawm carbon steel, stainless hlau, lossis tooj liab), uas yog compressed los ntawm lub tshuab los ua fins. Lub hauv paus ntawm cov fins yog nruj me ntsis adhered rau lub sab nrauv phab ntsa ntawm lub raj, nrog ib tug high tshav kub hloov coefficient thiab zoo heev tshav kub hloov kev ua tau zoo. Rolling finned tube

Cov fins yog du, burr free, wrinkle dawb, zoo nkauj thiab ci, thiab yooj yim los ntxuav. Raws li cov khoom siv cua sov thiab cov cua txias, lawv yooj yim tshem tawm cov dej condensation, thiab tsis yooj yim rau cov plua plav thiab nplai hauv ziab, cua sov, thiab lwm yam. Rolled fin tube fins yog transverse thiab trapezoidal, uas ua rau muaj zog fins thiab nthuav cov cua sov dissipation nto, yog li ua kom siv cov ntaub ntawv zoo tshaj plaws.

Squeezed finned tube yog cov khoom sib xyaw ntawm cov hlau, tooj liab, thiab txhuas raj uas tau muab dov rau hauv fins. Nws muaj qhov zoo ntawm kev sib raug zoo, tsis muaj thermal tsis kam, kev ua haujlwm zoo thaum tshav kub kub, siab zog, tsis tshua muaj dej ntws, muaj zog corrosion kuj, thiab tsis yooj yim deformed nyob rau hauv lub sij hawm ntev txias thiab kub ua hauj lwm tej yam kev mob, nrog ib tug ntev kev pab cuam lub neej.

Tag nrho cov dov fins yog du thiab tsis muaj burrs, yooj yim los ntxuav. Thaum ntub dej txias yog siv rau hauv cov cua sov thiab cua txias engineering, nws yog ib qho yooj yim los ua condensation rau saum npoo ntawm fins. Nyob rau hauv qhuav, cua sov, thiab lwm yam kub pauv kub, nto yog anodized, nrog zoo nkauj thiab dav xim, thiab muaj peev xwm tiv thaiv nto corrosion.

Aluminium dov finned tubes yog tsim los ntawm dov aluminium raj tag nrho, tsis muaj kev tiv thaiv thermal, siab zog, kub tsis kam rau kev poob siab thiab cov neeg kho tshuab kev co, zoo thermal expansion kev ua tau zoo, thiab loj expansion tshav kub exchanger nto. Thaum tshav kub kub exchangers ua los ntawm hom finned tube no muaj kev ua tau zoo dua piv rau cov khoom siv hluav taws xob los yog qhov txhab kub.

Raws li cov neeg siv xav tau, ntau yam tshwj xeeb ntawm steel sawb qhov txhab finned hlab thiab steel aluminium puas finned leeg tuaj yeem ua tiav.
