Ma armoelectric chiyeso chozizira

Thermoelectric zozizira magwiridwe antchito:

Musanagwiritse ntchito Kuzizira kwa thermoelertric, kuti mumvetsetse momwe akugwirira ntchito, module module, ma module a thermoelectric, ma booplectric module, pali awiri: m'modzi ndi joule kutentha QJ; Wina wapanga QK. Zomwe zimadutsa mkati mwa thermoelectric fornment kuti ipange moto wotentha, theka la kutentha kwa Joule amafalikira kumapeto, ndipo kutentha kwa mafilimu kumaperekedwa kuchokera kotentha TSIRIZA.

Kuzizira Kuzizira QC = Qπ-qj-qk

= (2P-2n) .tc.i-1 / 2Jj-k (th-tc)

Pomwe r imayimira kukana kwathunthu kwa awiri ndi k ndi mawonekedwe athunthu.

Kutentha kusungunuka kuchokera kumapeto qh = qπ + qj-qk

= (2p-2n) .th.i + 1 / 2i

Itha kuwoneka kuchokera pamapulogalamu awiri omwe ali pamwambawa omwe mphamvu yamagetsi yophatikizira ndi kusiyana pakati pa kutentha kosasunthika ndi kutentha kwa ozizira, komwe ndi mtundu wa "kutentha kwa"

QH-QC = IEM = P

Kuchokera pamwambapa, zitha kunenedwa kuti kutentha qh kunatha ndi banja lamagetsi kumapeto kwa mphamvu yamagetsi ndi kutulutsa kwamphamvu kwa madzi ozizira, komanso, zitha kunenedwa kuti Kutulutsa kozizira QC ndikofanana ndi kusiyana pakati pa kutentha komwe kunatulutsidwa ndi kumapeto kotentha ndi mphamvu yamagetsi.

Qh = p + qc

QC = QH-P

Njira yowerengera mphamvu yozizira yozizira ya thermoelectric

A.1 pomwe kutentha kumapeto kwa Th ndi 27 ℃ ± 1 ℃, kutentha kutentha ndi △ t = 0, ndi i = imax.

Kuchuluka kwamphamvu kwa QCmax (W) kumawerengedwa malinga ndi formula (1): QCMAX = 0.07NI

Komwe n - logarithm ya chipangizo cha thermoelectric, i - kutentha kutentha kwa chipangizocho (a).

A.2 Ngati kutentha kwa otentha ndi 3 ~ 40 ℃, mphamvu yayikulu kwambiri yozizira qcmax (w) iyenera kukonzedwa molingana ndi formula (2).

QCMAX = QCMAX × (1 + 0.0042 (27)]

.
