Te tātai mahi Themoelectric:
I mua i te tono i te matao thermoelectric, kia mohio ai koe ki tana mahi, nga tauira makariri, he rua: kotahi ko Joule Hot Qj; Ko tetahi atu ko te tohe i te wera te Qk. Ko nga mea kua paahitia i roto i te waahanga thermoectric ki te whakaputa i te wera o te wera, ka tukuna te hawhe ki te wera o te wera, ka tukuna te wera mai i te makariri Whakamutu.
Te Whakanuitanga makariri QC = Qπ-QJ-Qk
= (2p-2n) .tc.i-1 / 2j²r-k (th-tc)
Kei hea r e tohu ana i te whakaeke katoa o te takirua me te k te katoa o te waiherea.
Ko te wera i pakaru mai i te wera wera QH = Qπ + qj-Qk
= (2p-2n) .th.i + 1 / 2i²r-k (th-tc)
Ka kitea mai i nga waahanga e rua i runga ake nei ko te mana hiko whakauru ko te rereketanga i waenga i te wera i te mutunga o te wera ka uru te wera ki te mutunga o te "papu wera":
Qh-qc = i²r = p
Mai i te tātai i runga ake nei, ka taea te whakatau ko te wera i tukuna e tetahi taangata hiko i te mutunga o te mana hiko me te putanga makariri o te mutunga makariri, a ka taea te whakaoti i te Ko te putanga makariri qc he rite ki te rereketanga i waenga i te wera i tukuna e te pito wera me te mana hiko whakauru.
QH = P + QC
QC = qh-p
Te tikanga tatauranga o te mana makariri nui
A.1 Ka mutu te pāmahana i te wera wera te 27 ℃ ℃ ± ±, te rereketanga o te pāmahana ko te △ t = 0, me te = imax.
Ko te mana nui o te mana o te VCMAX (W) ka kiia kia rite ki te tauira (1): QCMAX = 0.07ni
Kei hea te N - Logarithm o te Pūrere Thermoelectric, i - te rereketanga o te pāmahana o te taputapu (a).
A.2 Mena ko te pāmahana o te mata wera ko te 3 ~ 40 ℃, me whakatikatika te mana o te mana nui o te QCMAX kia rite ki te tauira (2).
QCMAX = QCMAX × [1 + 0,0042 (th - 27)]
(2) I roto i te tātai: QCMAX - Te pāmahana wera th = 27 ℃ ± te mana makariri (W
