Yuav ua li cas xaiv qhov zoo yog qhov pib ntawm daim ntawv thov ntawm cov thermoelectric modules, thermoelectric txias modules, TE modules. Tsuas yog los ntawm kev xaiv cov thermoelectric txias module tuaj yeem ua tiav qhov kev cia siab ntawm qhov ntsuas kub. Ua ntej xaiv Peltier module, TEC module, thermoelectric module, nws yog ib qho tsim nyog yuav tsum tau ua ntej kom meej meej cov kev xav tau ntawm cov cua txias, lub hom phiaj ntawm kev ua kom txias yog dab tsi, cov tshuab cua txias yuav xaiv li cas, hom kev siv hluav taws xob zoo li cas, lub hom phiaj kub yog dab tsi, thiab yuav muab lub zog npaum li cas. Yog tias koj npaj yuav xaiv cov thermoelectric txias modules, thermoelectric modules, peltier modules, TEC module, peltier ntsiab los ntawm Beijing Huimao Cooling Equipment Co., Ltd., koj tuaj yeem txiav txim siab tus qauv tsim nyog los ntawm cov kauj ruam xaiv hauv qab no.

1. Kwv yees lub tshav kub load

Thaum tshav kub kub thauj khoom yog hais txog cov cua kub uas yuav tsum tau muab tshem tawm kom txo qhov kub ntawm lub hom phiaj cua txias mus rau ib theem teev nyob rau hauv ib puag ncig kub, nrog rau chav tsev yog W (watt). Thaum tshav kub kub loads feem ntau muaj xws li active loads, passive loads, thiab lawv ua ke. Lub active tshav kub load yog lub tshav kub load generated los ntawm lub hom phiaj txias nws tus kheej. Passive heat load yog lub tshav kub load tshwm sim los ntawm sab nraud hluav taws xob, convection thiab conduction. Active load xam mis

Qactive = V2/R = VI = I2R;

Qactive = Active tshav kub load (W);

V = Qhov hluav taws xob siv rau lub hom phiaj tub yees (V);

R = Resistance ntawm lub hom phiaj tub yees;

I = Tam sim no ntws los ntawm lub hom phiaj txias (A)

Radiant tshav kub load yog lub tshav kub load kis mus rau lub hom phiaj khoom los ntawm electromagnetic hluav taws xob. Kev suav cov mis:

Qrad = F es A (Tab4 – Tc4);

Qrad = Radiant tshav kub Load (W);

F = tus qauv zoo (tus nqi phem tshaj = 1);

e = emissivity (tus nqi phem tshaj = 1);

s = Stefan-Boltzmann tas li (5.667 X 10-8W/m² k4);

A = Qhov chaw txias (m²);

Tamb = Ambient Temperature (K);

Tc = TEC – Cold end temperature (K).

Convective tshav kub load yog lub tshav kub load kis tau los ntawm cov kua uas dhau los ntawm qhov chaw ntawm lub hom phiaj khoom los ntawm sab nraud. Cov mis laij lej yog:

Qconv = hA(Tair – Tc);

Qconv = Convective tshav kub Load (W)

h = Convective heat transfer coefficient (W/m ² °C) (tus nqi ntawm lub dav hlau dej ntawm ib qho chaw cua) = 21.7 W / m ² ° C;

A = Qhov chaw (m²);

Tair = Ambient kub (°C);

Tc = Txias kawg kub (°C);

Conductive heat load yog lub tshav kub thauj khoom los ntawm sab nraud los ntawm cov khoom sib cuag ntawm qhov chaw ntawm lub hom phiaj. Cov mis laij lej yog:

Qcond = k A DT/L;

Qcond = Transferred tshav kub load (W);

k = Thermal conductivity ntawm cov khoom siv thermal conductive (W / m ° C);

A = Qhov chaw hla ntawm cov khoom siv thermal conductive (m ²);

L = Length ntawm tshav kub conduction txoj kev (m)

DT = Kub qhov sib txawv ntawm txoj kev tshav kub (°C) (feem ntau yog xa mus rau qhov kub thiab txias los yog lub dab dej kub kub rho tawm qhov txias kawg.)

Rau kev sib xyaw ua ke cua sov ntawm convection thiab conduction, cov qauv kev suav yog:

Q passive = (A x DT)/(x/k + 1/h);

Qpassive = Kub load (W);

A = Tag nrho thaj tsam ntawm lub plhaub (m2);

x = Thickness ntawm rwb thaiv tsev txheej (m)

k = Rwb thaiv tsev thermal conductivity (W / m ° C);

h = Convective heat transfer coefficient (W/m² °C)

DT = Kub qhov sib txawv (°C).

2. xam tag nrho cov cua sov load

Los ntawm thawj kauj ruam, peb tuaj yeem suav tag nrho cov khoom cua sov ntawm lub hom phiaj ntawm lub tub yees.

Piv txwv li, nyob rau hauv qhov tseeb project, lub active tshav kub load yog 8W, lub radiant tshav kub load yog 0.2W, lub convective tshav kub load yog 0.8W, conductive tshav kub load yog 0W, thiab tag nrho cov tshav kub load yog 9W.

3. Txhais qhov kub thiab txias

Txhais qhov kub kawg kub, txias kawg kub thiab txias txias qhov sib txawv ntawm daim ntawv tub yees. Piv txwv li nyob rau hauv qhov project tiag tiag, qhov kub thiab txias yog 27 ° C, lub hom phiaj txias txias yog -8 ° C, thiab qhov sib txawv ntawm qhov txias txias DT = 35 ° C.

Piv txwv tias tag nrho cov cua sov ntawm lub hom phiaj txias yog kwv yees li 9W raws li kev kwv yees yav dhau los, qhov zoo tshaj plaws Qmax tuaj yeem tau txais li 9/0.25 = 36W, thiab qhov siab tshaj plaws Qmax li 9/0.45 = 20. Tshawb nrhiav cov khoom catalog ntawm Beijing Huimao Cooling Equipment Co., Ltd rau thermoelectric txias modules, peltier modules, peltier li, peltier ntsiab.TEC modules thiab nrhiav cov khoom nrog Qmax xws li 20 txog 36.
