Kev xaiv thiab kev teeb tsa ntawm lub tshuab cua sov yog cov theem tseem ceeb hauv kev npaj lub tsev nyob lossis chav tsev. Tus naj npawb ntawm cov radiators yuav tsum nyob ntawm lub zog ntawm cov khoom siv thiab thaj tsam ntawm chav tsev. Niaj hnub no, aluminium radiators yog suav tias yog nrov tshaj plaws. Cov yam ntxwv txuj ci, nrog rau qhov zoo thiab qhov tsis zoo ntawm cov cua sov no yuav tau tham hauv kab lus no.

Kev piav qhia

Lub ntsiab tseem ceeb ntawm cov khoom siv cua sov no yog cov ntu uas ntim dej. Dej yog tus yam ntxwv los ntawm lub peev xwm kub kub, uas tso cai rau nws khaws cov thermal zog rau lub sijhawm ntev, tsis tu ncua hloov mus rau qhov chaw nyob ib puag ncig.

Ntau yam

Aluminium radiators (cov kev qhia tshwj xeeb tau tham hauv qab no) raws li hom kev tsim khoom, muaj ob hom:

Extrusion.

Hom kawg suav nrog ntu cais, lawv tus lej tuaj yeem raug txo lossis nce ntxiv thaumtsim nyog thaum twg los tau. Lub tshuab cua sov extrusion muaj ib qho kev sib xyaw ua ke ntawm cov ntu, lawv cov naj npawb ntawm 6 txog 12. Cov neeg siv khoom nws tus kheej xaiv, tsom mus rau cov yam ntxwv ntawm lub tsev lossis chav tsev, hom khoom twg haum rau nws zoo tshaj plaws.

txheej txheem kub hloov pauv

Los ntawm cov raj xa dej, cov dej kub ntws mus rau hauv qab ntawm ntu, tom qab ntawd, vim yog convection, nws txav mus, yog li ua kom cua sov nyob ib puag ncig los ntawm cov vaj tsev aluminium. Cov dej txias dhau los ntawm txhua ntu, tom qab ntawd nws txuas ntxiv nws txoj hauv kev los ntawm cov cua sov los ntawm cov kav xa rov qab.

Cov ntu ntawm lub tshuab cua sov yog tsim los ntawm nias aluminium nrog qhov sib ntxiv ntawm ib qho me me ntawm silicon. Txhua ntu muaj cov khoom qis thiab sab sauv, uas txuas nrog cov kab ntsug ntsug thiab cov hlau fins uas ua rau kom muaj cua sov los ntawm kev nthuav dav ntawm thaj chaw. Cov seem yog interconnected los ntawm txoj kev threaded ntsiab kaw nrog paronite gaskets.

Cov khoom siv cua sov sau cov ntu, cua sov, ib txhij sau thiab tso tawm thermal zog rau hauv chav. Vim lub thermal conductivity zoo ntawm txhuas, cov cuab yeej no muaj lub siab inertia thiab efficiency, tsis zoo li bimetallic thiab cam khwb cia hlau counterparts.

Qhov ntau seem, qhov siab dua qhov hloov hluav taws xob ntawm aluminium radiators. Txawm li cas los xij, nws tsis tsim nyogtau nqa mus, raws li tus lej ntau dhau yuav ua rau qee qhov ntawm lawv ua tsis tau siv ballast. Hauv qhov no, tus naj npawb ntawm ntu yuav tsum raug xam raws li lub cev yam ntxwv ntawm lub tsev.

Tseem muaj cov khoom siv hluav taws xob muaj zog ntxiv. Cov yam ntxwv ntawm cov cuab yeej no tso cai rau koj los teeb tsa tus naj npawb ntawm cov seem, txij li lawv tus kheej tswj cov kua dej siab.

Heater section muaj tus qauv qhov ntev:

  • Height - 350-1000 mm.
  • Qhov tob - 110-140 mm.
  • Phab ntsa thickness - 2-3 mm.
  • Heating area - 0.4-0.6 m2.
  • Lub ntim ntawm txhuas radiator yog 0.35-0.5 litres.

Lub tshav kub hloov ntawm lub tshuab cua sov yog 50-60% hluav taws xob, convection - 40-50%.

  • Low thermal inertia.
  • Small mass.
  • High heat dissipation.
  • Cov cua sov no yog qhov ua tau zoo, thiab qhov tseem ceeb tshaj plaws - tiv taus cov tshuaj lom neeg ntawm cov dej txias.
  • Tus nqi pheej yig heev, uas yog qhov tshwj xeeb tau txais txiaj ntsig zoo ntawm cov khoom siv no.
  • Lub teeb yuag ntawm cov qauv ua rau nws yooj yim rau mount aluminium cua sov radiators. Cov yam ntxwv ntawm cov cuab yeej no yog nyob rau theem siab.
  • Lawv yooj yim tu - ntxuav thiab ntxuav.
  • Cov khoom siv tau them nrog cov txheej tshwj xeeb uas tiv taus cua sov uas tsis tev tawm.
  • Tus tsim yog xav tawm hauv txoj kev uas cov huab cua siab tshaj plaws yog siv nrog qhov me me.
  • Yog xav tau, ntawm aluminium radiators (tus yam ntxwv yuav zoo dua), koj tuaj yeem nruab lub taub hau thermal uas yuav tso cai rau koj tswj qhov kub hauv chav.
  • chav sov sai sai, uas tseem ceeb heev rau lub caij ntuj no.

Flaws

Ntxiv rau qhov pom tseeb qhov zoo, aluminium cua sov radiators, cov yam ntxwv ntawm cov uas tau tham saum toj no, kuj muaj qee qhov tsis zoo. Ib qho ntawm lawv yog qhov tsis muaj zog ntawm cov phab ntsa kom cia li poob siab hauv cov cua sov. Kev xaiv ntawm tus qauv radiator yuav tsum tau ua kom zoo zoo. Yog hais tias, piv txwv li, lawv tau tsim rau tej yam kev mob nyob rau hauv ltalis, ces rau Russia qhov tseeb lawv lub zog yuav tsis txaus. Txij li thaum no lub siab "dhia" muaj zog thiab ntau zaus. Thiab qee zaum nws yog ob peb zaug siab dua tus qauv tus nqi.

Lwm qhov tsis zoo yog qhov siab rhiab heev rau impurities muaj nyob hauv dej kub. Qhov zoo ntawm cov coolant nkag mus rau hauv peb lub tshuab cua sov tawm ntau yam xav tau. Hauv dej, koj tuaj yeem pom cov neeg kho tshuab impurities nyob rau hauv daim ntawv ntawm xeb, xuab zeb, pob zeb me me. Kev sib cuag nrog cov phab ntsa sab hauv ntawm tag nrho cov no yog qhov ua rau corrosion. Ntxiv acidity ntawm lub coolant tuaj yeem ua rau oxidation sai. Qhov no yuav tsum tau coj mus rau hauv tus account thiab hloov cov khoom qub raws sijhawm rau cov tshiab aluminium radiators (cov yam ntxwv tau qhia saum toj no).

Cas tsis ua haujlwm

Nws paub tias hauv cov nroj tsuag cua sov cov dej nkag mus rau kev npaj alkaline, thiab thaum sib cuagaluminium radiators nrog ib puag ncig alkaline, muaj kev tso tawm ntawm cov hydrogen dawb. Thaum tsis muaj cov khoom siv degassing tsis siv neeg, hydrogen accumulating hauv aluminium radiators ua rau lawv tawg.

Tshuaj txo qis hydrogen los ntawm lub coolant tshwm sim hauv txhua lub tshuab cua sov yam tsis muaj kev zam. Txawm li cas los xij, cov cua vents ntsia tau rau hauv qhov system tiv nrog kev tshem tawm cov roj tso tawm yam tsis muaj teeb meem. Cov aluminium alloy, los ntawm cov khoom siv cua sov tau tsim, ua lub luag haujlwm ntawm cov khoom siv hauv cov tshuaj tiv thaiv, vim li ntawd, tus nqi ntawm hydrogen, nrog rau cov tshuaj tiv thaiv, nce ntau zaus.

Yog li, txawm tias muaj kev ua txhaum me ntsis hauv kev ua haujlwm ntawm cov cua sov (qhov cua tsis qhib lossis txhaws) tuaj yeem ua rau tawg ntawm lub tshuab hluav taws xob aluminium, ob qho tib si cam khwb cia thiab extruded. Hauv qhov no, qee qhov xwm txheej, kev siv cov khoom siv cua sov aluminium yog qhov tsis zoo.

Xaiv tus lej ntawm ntu

Yog tias koj xaiv yuav lub tshuab hluav taws xob txhuas, ces koj yuav muaj peev xwm xam tus kheej seb koj yuav tsum tau ua kom sov ib chav twg. Nws tsis tas yuav muaj kev txawj lej tshwj xeeb txhua.

Kev suav, koj yuav tsum paub lub zog ntawm lub tshuab hluav taws xob txhuas (P), uas, raws li txoj cai, tau qhia hauv daim ntawv qhia kev, thiab koj tseem yuav tau suav cov cheeb tsam ntawm qhov chaw. cua sovthaj chaw (S). Kev suav yog ua raws li cov qauv hauv qab no:

S × 100 / P=N, qhov twg N yog tus lej ntawm ntu.

Piv txwv li, thaj tsam ntawm chav tsev yog 36 m 2, rau lub tshuab hluav taws xob aluminium, tus qauv P tus nqi yog 190 W. Txoj kev no:

N=36 × 100 / 190=18, 95.

Yog li, 19 ntu yuav tsum tau ua kom sov peb chav.
