Monometallic finned tubes thiab bimetallic finned raj yog hom finned raj, txawv hauv qab no. Finned tubes, tseem hu ua cov kav dej kub, muab faib ua ib leeg hlau finned leeg thiab bimetallic finned leeg.
Tus neeg hlau fin raj yog qhov txhab nrog lub raj txhuas txhuas, hu uaaluminium dov fin tube, uas tsis yog-hu rau thermal kuj, siab zog, tsis kam mus rau tshav kub thiab txhua yam kev co, zoo thermal expansion kev ua tau zoo, thiab muaj ib tug considerably ncua tshav kub exchanger nto. Lub tshav kub exchanger ua los ntawm no finned raj yog zoo dua tandem los yog winding tshav kub exchanger thiab yog ib tug ntau yam ntawm tshav kub exchanger. Txhua tus neeg hlau finned raj kuj tuaj yeem dov ncaj qha los ntawm cov raj hlau lossis cov raj tooj liab.
Bimetallic composite finned tubes tau muab faib ua steel-aluminium composite finned leeg thiab tooj liab-aluminium composite finned leeg. Lub steel aluminium puas finned raj yog ua los ntawm (steel raj, txhuas raj; LOSSIS stainless hlau raj, txhuas raj) tom qab composite thiab ces dov tawm ntawm fin, tooj liab thiab composite fin tube txhuas los ntawm (tooj tooj liab, txhuas raj) tom qab compounding thiab tom qab ntawd dov tawm ntawm lub fin, nrog nruj sib koom ua ke, me me thermal tsis kam, zoo tshav kub hloov kev ua tau zoo, siab zog, me ntws poob, muaj zog tiv thaiv corrosion, tsis yooj yim rau deform nyob rau hauv lub sij hawm ntev kub thiab txias tej yam kev mob, ntev kev pab cuam lub neej thiab lwm yam zoo.
Cov khoom siv dov fin yog burr-dawb, wrinkle-dawb, yooj yim los ntxuav, thiab yooj yim kom tshem tawm condensation nyob rau sab nrauv ntawm lub fin thaum ntub dej txias hauv cov cua sov thiab cua txias, thiab tsis yooj yim rau plua plav thiab nplai hauv cua sov kom qhuav. thiab lwm lub sijhawm sib pauv cua sov.
