Kev Taw Qhia Rau Thermoelectric txias module

Thermoelectric thev naus laus zis yog ib qho txheej txheem tswj kev kub raws li Peltier effect. Nws tau tshawb pom los ntawm JCA Peltier hauv xyoo 1834, qhov xwm txheej no cuam tshuam nrog kev cua sov lossis txias ntawm qhov sib koom ua ke ntawm ob lub thermoelectric khoom (bismuth thiab telluride) los ntawm kev dhau tam sim no los ntawm qhov sib koom ua ke. Thaum lub sijhawm ua haujlwm, tam sim no ncaj qha ntws los ntawm TEC module ua rau cua sov hloov pauv los ntawm ib sab mus rau lwm qhov. Tsim ib sab txias thiab kub. Yog tias qhov kev taw qhia ntawm tam sim no raug thim rov qab, sab txias thiab kub hloov pauv. Nws lub zog txias kuj tuaj yeem hloov kho los ntawm kev hloov nws qhov tam sim no ua haujlwm. Ib qho khoom siv txias ib theem (Daim Duab 1) muaj ob lub phaj ceramic nrog p thiab n-hom semiconductor khoom (bismuth, telluride) ntawm cov phaj ceramic. Cov ntsiab lus ntawm cov khoom siv semiconductor txuas nrog hluav taws xob hauv series thiab thermally hauv parallel.

Cov khoom siv cua txias thermoelectric, Peltier device, TEC modules tuaj yeem suav hais tias yog ib hom twj tso kua mis thermal solid-state, thiab vim nws qhov hnyav tiag tiag, qhov loj me thiab qhov nrawm ntawm kev teb, nws yog qhov tsim nyog heev rau kev siv ua ib feem ntawm cov tshuab cua txias hauv tsev (vim muaj qhov txwv ntawm qhov chaw). Nrog rau qhov zoo xws li kev ua haujlwm ntsiag to, tsis tawg, tiv taus kev poob siab, lub neej ntev dua thiab yooj yim txij nkawm, cov khoom siv cua txias thermoelectric niaj hnub, peltier device, TEC modules muaj ntau daim ntawv thov hauv cov teb ntawm cov khoom siv tub rog, aviation, aerospace, kev kho mob, kev tiv thaiv kab mob sib kis, cov khoom siv sim, cov khoom siv rau cov neeg siv khoom (dej txias, tsheb txias, tub yees hauv tsev so, tub yees cawv, tub yees me me, ntaub so pw txias & sov, thiab lwm yam).

Niaj hnub no, vim nws qhov hnyav tsawg, me me lossis muaj peev xwm thiab tus nqi qis, thermoelectric txias yog siv dav hauv kev kho mob, khoom siv tshuaj, aviation, aerospace, tub rog, spectrocopy systems, thiab cov khoom lag luam (xws li lub tshuab faib dej kub thiab txias, cov tub yees portable, lub tshuab txias tsheb thiab lwm yam).

Kev Taw Qhia Txog Daim Ntawv Thov Formulae rau TEC module

Q_c= 2N[α(T_c+273)-LI²/2σS-κs/Lx(T_h- T_c) ]

△T= [ Iα(T_c+273)-LI/²2σS] / (κS/L + I α]

U = 2 N [ IL /σS + α(T_h- T_c)]

ε = Q_c/UI

Q_h= Q_{c +} IU

△T_{siab tshaj plaws}= T_h+ 273 + κ/σα² x [ 1-√2σα²/κx (T_h+273) + 1]

I_{siab tshaj =}κS/ Lαx [√2σα²/κx (T)_h+273) + 1-1]

Iεsiab tshaj =ασS (T_h- T_c) / L (√1+0.5σα²(546+ T)_h- T_c)/ κ-1)
