Te mahi whakamatao hau wera

Te tataunga mahi whakamatao whakamatao:

I mua i te tono i te whakamahana whakamahana werawera, kia maarama ake ai ki tana mahi, inaa, ko te pito matao o te peltier module, ko nga waeine thermoelectric, ka momi i te wera o te taiao, e rua: kotahi ko te wera joule Qj; Ko tetahi atu ko te wera kawe Qk. Ka haere te naianei ki roto o te huānga thermoelectric ki te whakaputa i te wera joule, ko te haurua o te wera joule ka tukuna ki te pito makariri, ko te haurua ka tukuna ki te pito wera, ka tukuna te wera kawe mai i te pito wera ki te pito makariri.

Hanga makariri Qc=Qπ-Qj-Qk

= (2p-2n).Tc.I-1/2j²R-K (Th-Tc)

Ko te R e tohu ana i te tapeke parenga o te takirua me te K ko te katoa o te wera wera.

Te wera i marere mai i te pito wera Qh=Qπ+Qj-Qk

= (2p-2n).Th.I+1/2I²R-K (Th-Tc)

Ka kitea mai i nga tauira e rua o runga ake nei ko te mana hiko whakauru he rite tonu te rereketanga i waenga i te wera i marara e te pito wera me te wera ka mauhia e te pito makariri, he momo "paa wera" :

Qh-Qc=I²R=P

Mai i te tauira i runga ake nei, ka taea te whakatau ko te wera Qh e tukuna ana e te tokorua hiko i te pito wera he rite ki te tapeke o te mana hiko whakauru me te putanga matao o te pito makariri, me te rereke, ka taea te whakatau 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

Tikanga tātai o te mana whakamatao thermoelectric mōrahi

A.1 Ina 27 ℃ ± 1 ℃ te pāmahana i te pito wera Th, ko te rerekētanga o te pāmahana ko △T=0, me I=Imax.

Ka tatauhia te mana whakamatao nui Qcmax(W) i runga i te tauira (1): Qcmax=0.07NI

Kei hea te N - logarithm o te taputapu thermoelectric, I - te rereketanga o te pāmahana teitei o te waa o te taputapu (A).

A.2 Mena ko te 3 ~ 40 ℃ te pāmahana o te mata wera, me whakatika te mana whakamahana teitei Qcmax (W) kia rite ki te tauira (2).

Qcmax = Qcmax×[1+0.0042(Th--27)]

(2) I roto i te tātai: Qcmax — wera mata wera Th=27 ℃ ± 1 ℃ te mana whakamatao teitei (W), Qcmax∣Th — te wera wera o te mata Th — te mana whakamahana teitei (W) i te pāmahana ine mai i te 3 ki te 40 ℃
