Internally grooved tooj liab raj, tseem hu ua Inner Grooved Tubes (IGT), yog ib hom tshwj xeeb ntawm tshav kub exchanger raj. Lawv lub ntsiab lus txhais yog lub ntsej muag du thiab lub ntsej muag sab hauv nrog cov qauv meej ntawm grooves lossis fins. Cov qauv sab hauv no ua rau muaj txiaj ntsig zoo rau kev hloov pauv hluav taws xob los ntawm 20% mus rau 30% piv rau du - cov hlab ntsa.

Cov ntsiab lus tseem ceeb thiab lawv qhov cuam tshuam rau kev ua tau zoo
Kev ua tau zoo ntawm IGT yog txiav txim siab los ntawm ntau qhov sib cuam tshuam geometric tsis. Cov lus hauv qab no qhia txog cov ntsiab lus tseem ceeb no thiab lawv cov kev cuam tshuam ntawm kev hloov hluav taws xob thiab kev ua haujlwm.
| Parameter | Hom Ntau Yam / Hom Loj | Kev cuam tshuam rau kev hloov cua sov & kev xaiv xaiv |
|---|---|---|
| Sab nraud Diameter (OD) | 9.52mm, 7.00mm, 7.94mm, 6.35mm, 5 hli | Cov diameters me me txuag cov khoom siv thiab qhov chaw, txhawb nqa miniaturization tiam sis. Txawm li cas los xij, ib txoj kab me me dhau los ua rau cov tub yees txaus siab ua haujlwm, ua rau lub zog siab poob. |
| Base Phab Ntsa Thickness | 0.20-0.30 hli | Lub phab ntsa nyias ua kom cov cua sov ua kom zoo tab sis cuam tshuam lub zog ntawm lub zog, ua rau muaj kev pheej hmoo ntawm kev tawg, tawg, lossis deformation thaum khoov thiab vuam. |
| Fin Qhov siab | 0.10-0.25 hli | Lub fins siab dua ua rau cov cua sov hloov mus rau qhov chaw thiab cuam tshuam rau cov yeeb yaj kiab ua yeeb yaj kiab ua kom zoo dua, txhim kho kev ua haujlwm. Nws yog txwv los ntawm kev tsim muaj peev xwm. |
| Helix Angle | Qhov tshwj xeeb zoo tshaj plaws (vim los ntawm kev tsim) | Lub kaum sab xis loj tuaj yeem ua rau muaj kev kub ntxhov ("swirl") thiab cov coefficient hloov hluav taws xob, tab sis kuj ua rau lub siab poob. Yuav tsum pom qhov sib npaug zoo. |
| Fin Tip Angle | Nws tuaj yeem qis li ~ 20 degree | Ib lub kaum me me ua rau thaj tsam ntawm qhov chaw thiab thins cov yeeb yaj kiab ua kua. Txawm li cas los xij, yog tias me me dhau lawm, nws ua rau lub fins ntawm cov qauv kev ntseeg siab thaum lub sij hawm lub raj nthuav dav, ua rau lub cev qhuav dej thiab txo qis kev ua haujlwm. |
| Number of Fins (grooves) | Optimized rau tej diameters | Ntau cov fins muab ntau qhov chaw nucleation rau boiling tab sis tuaj yeem ua kom sib nrug nruj heev. Qhov no txo cov kua dej sib tov thiab ua kom cov kua nplaum ua kom tuab, uas tuaj yeem cuam tshuam cov txiaj ntsig. |
| Groove hauv qab dav | Dav dav feem ntau zoo dua | Lub hauv paus dav dua yog qhov zoo rau kev hloov pauv cua sov tab sis yuav tsum sib npaug nrog kev tswj xyuas lub zog thaum lub sijhawm tsim khoom thiab kev sib dhos. |
Kev Xaiv Txoj Cai rau Optimized Heat Transfer
Xaiv txoj cai IGT suav nrog ntsuas qhov ua haujlwm thermal nrog kev txwv kev siv tshuab thiab hydraulic. Nov yog lub hauv paus ntsiab lus rau kev xaiv:
Txhais cov ntsiab lus tseem ceeb:Pib nrog thawj daim ntawv thov (evaporator los yog condenser), yuav tsum tau tshav kub load, refrigerant hom, thiab tso cai rau lub siab poob.
Ua ntej qhov tseem ceeb Parameter rau koj lub hom phiaj:
Rausiab tshaj qhov kub hloov(feem ntau hauv cov evaporators): Ua ntej cov raj uas muaj qhov siab dua fin, lub kaum sab xis me dua, thiab qhov loj dua wetted perimeter.
Raubalanced kev ua tau zoo nrog kev txo qis qis(feem ntau nyob rau hauv condensers los yog ntev circuits): Lub kaum sab xis helix thiab ua tib zoo optimization ntawm fin suav yog ib qho tseem ceeb kom tsis txhob muaj kev tawm tsam ntau dhau.
Xyuas kom muaj kev ruaj ntseg ntawm txhua yam:Xyuas kom tseeb tias lub hauv paus phab ntsa thickness thiab fin geometry (lub kaum sab xis, zawj dav) muab lub zog txaus rau kev tsim cov txheej txheem xws li U- dabtsi yog khoov thiab brazing, nrog rau kev ua haujlwm siab.
Xav txog qhov System Trends:Ua ke nrog kev lag luam hloov mus rau me me diameters rau compactness thiab cov ntaub ntawv txuag, tab sis ib txwm siv tau tias qhov txo txoj kab uas hla tsis tsim kev tsis txaus siab nyob rau hauv koj cov txheej txheem tshwj xeeb.
Xaiv qhov zoo tshaj plaws nyob rau hauv grooved tooj liab raj yog ib tug multi-variable optimization hauj lwm. Tsis muaj ib qho "zoo tshaj" specification; lub raj zoo tagnrho yog ib qho uas cov geometric parameters - txoj kab uas hla, fin qhov ntev, thiab lub kaum sab xis helix - sib haum xeeb kom xa cov cua kub hloov mus rau qhov zoo tshaj plaws thaum tuav cov txheej txheem robustness thiab cov kua dej txaus txaus rau daim ntawv thov.
