Dab tsi yog qhov zoo ntawm finned tube heat exchangers piv rau lwm cov cua kub exchangers?

Dab tsi yog qhov zoo ntawm finned tube heat exchangers nyob rau hauv tshav kub exchangers?
1. Lub siab thermal conductivity Performance index yog vim lub complex flow channel tsim los ntawm inversion ntawm cov vuas sib txawv, uas ua rau cov kua los nthuav qhia ib tug rotating peb-dimensional flow nyob rau hauv lub ntws channel ntawm corrugated daim hlau. Nyob rau hauv qis ntws tsis kam (Re=50-200), nws tuaj yeem ua rau qhov chaw ntws. Yog li ntawd, nws feem ntau suav hais tias yog 3-5 zaus ntawm lub plhaub thiab lub raj hom.
2. Qhov nruab nrab kub qhov sib txawv yog qhov loj, thaum tus Tsov tus tw kub sib txawv me me. Nyob rau hauv lub raj xa hluav taws xob lub plhaub hluav taws xob, ob hom kua dej yog nyob rau ntawm lub raj sab thiab lub plhaub sab, thiab cov qauv ntws tag nrho yog staggered. Feem ntau qhov nruab nrab qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv yog qhov me me, thiab finned tube heat exchangers feem ntau siv rau pem hauv ntej los yog rov qab ntws txoj kev, nrog kev kho coefficient feem ntau nyob ib ncig ntawm 0.95. Tsis tas li ntawd, cov dej ntws ntawm cov cua txias thiab cov cua kub exchangers nyob rau hauv finned tube heat exchangers yog tib yam thiab tsis muaj lateral flow, uas txhawb lawv txoj kev loj hlob.
3. Vim nws cov hneev taw me me thiab cov qauv sib txuas, tag nrho qhov chaw sib pauv cua sov nyob rau hauv lub lag luam ntim yog 2-5 lub sij hawm ntawm lub plhaub thiab lub raj kub exchangers, uas txawv ntawm qhov chaw txij nkawm uas yuav tsum tau faus los yog tshem tawm mus rau ua kom tiav tib qho kev sib pauv cua sov ua haujlwm. Kwv yees li 1/5-1/8 ntawm lub plhaub thiab lub raj cua kub exchangers yog finned tube heat exchangers.
4. Tag nrho cov tshav kub hloov chaw lossis cov kauj ruam muaj pes tsawg leeg tuaj yeem hloov tau yooj yim. Yog tias ntau daim hlau raug tsa los yog qis dua, tag nrho cov tshav kub hloov pauv tuaj yeem nce lossis txo; Los ntawm kev hloov cov phaj sib lawv liag los yog hloov ntau daim hlau, cov txheej txheem txheej txheem tuaj yeem ua tiav, thiab hloov cov cua sov tshiab tuaj yeem ua ke. Txawm li cas los xij, tag nrho cov tshav kub hloov chaw ntawm lub plhaub thiab lub raj kub hloov pauv tsis tuaj yeem nce ntxiv.
5. Lub phaj thickness ntawm lub plhaub thiab lub raj kub exchangers yog tsuas yog 0.4-0.8mm, thiab phab ntsa phaj thickness ntawm plhaub thiab raj kub exchangers yog 2.0-2.5mm. Lub plhaub ntawm lub plhaub thiab lub raj cua kub exchangers yog hnyav dua li cov qauv ntawm finned tube heat exchangers, feem ntau tsuas yog li 1/5 ntawm qhov hnyav ntawm lub plhaub thiab lub raj kub exchangers.
6. Xaiv cov kev xaiv pheej yig dua rau tib cov khoom siv raw. Thaum lub tshav kub hloov pauv tsis hloov pauv, tus nqi ntawm finned tube heat exchangers txo los ntawm 40 feem pua ​​​​rau 60 feem pua ​​​​piv rau lub plhaub thiab lub raj kub exchangers.
7. Lub tshav kub hloov pauv ntawm qhov yooj yim finned tube kub exchanger yog ua los ntawm cov khoom siv stamped, nrog rau qib siab ntawm cov qauv thiab tuaj yeem ua rau ntawm qhov loj. Plhaub thiab raj kub exchangers feem ntau yog xuas tes ua.
8. Ncej hom finned raj kub exchanger. Yog hais tias lub thauj tog rau nkoj ntsia liaj qhov rooj raug tso tawm thiab clamped, lub phaj bundles yuav tsum tau loosened thiab lub disc yuav raug tshem tawm los ntawm lub tshuab ntxhua khaub ncaws, uas yog yooj yim heev rau tag nrho cov tshav kub exchanger txheej txheem uas yuav tsum tau nquag tu lub tshuab.
9. Lub thermal puas ntawm lub tshav kub hloov phaj ntawm lub me me finned tube cua sov exchanger tsuas yog tshwm sim los ntawm lub plhaub phaj tau raug rau saum huab cua, thiab cov cua kub poob yuav tsis quav ntsej, tsis tas yuav tsum muaj kev ntsuas rwb thaiv tsev. Tab sis lub plhaub thiab lub raj cua kub exchangers muaj cov thermal puas thiab ntau cov rwb thaiv tsev.
10. Plhaub thiab raj kub exchangers nrog ib tug me me ntim ntawm 10 mus rau 20 feem pua.
11. Vim tias qhov sib txawv me me ntawm qhov chaw hloov hluav taws xob thiab qhov tsis sib xws ntawm cov cua sov hloov mus rau qhov chaw, qhov kev ua haujlwm siab ntawm ib chav tsev ntev yog ntau dua, ua rau muaj kev puas tsuaj ntau dua li cov kav dej ib txwm muaj.
12. Vim muaj kev kub ntxhov loj, kev ntsuas tsis yooj yim, thiab nws qhov ntsuas qhov ntsuas tsuas yog 1/3-10/10 ntawm lub plhaub thiab lub raj cua kub exchangers.
