Thermoelectric jụrụ ịrụ ọrụ

Mgbakọ arụmọrụ ọkụ ọkụ ọkụ:

Tupu itinye thermoelectric jụrụ, iji ghọtakwuo arụmọrụ ya, n'ezie, njedebe oyi nke modul peltier, modul thermoelectric, na-ekpo ọkụ na gburugburu, e nwere abụọ: otu bụ joule okpomọkụ Qj; Nke ọzọ bụ conduction okpomọkụ Qk. Ihe dị ugbu a na-agafe n'ime ihe ọkụ ọkụ ọkụ iji mepụta okpomọkụ joule, ọkara nke okpomọkụ joule na-ebufe na njedebe oyi, ọkara nke ọzọ na-ebufe na njedebe na-ekpo ọkụ, a na-ebute okpomọkụ conduction site na njedebe na-ekpo ọkụ na njedebe oyi.

Mmepụta oyi Qc=Qπ-Qj-Qk

= (2p-2n).Tc.I-1/2j²R-K (Th-Tc)

Ebe R na-anọchi anya nguzogide otu ụzọ na K bụ mkpokọta thermal conductivity.

Okpomọkụ na-esi na njedebe dị ọkụ chụpụ Qh=Qπ+Qj-Qk

= (2p-2n).Th.I+1/2I²R-K (Th-Tc)

Enwere ike ịhụ site na usoro abụọ a dị n'elu na ike eletrik ntinye bụ kpọmkwem ihe dị iche n'etiti okpomọkụ na-ekpochapụ site na njedebe na-ekpo ọkụ na ọkụ na-ekpo ọkụ na njedebe oyi, nke bụ ụdị "mgbapụta ọkụ" :

Qh-Qc=I²R=P

Site na usoro a dị n'elu, enwere ike ikwubi na okpomọkụ Qh na-esi na di na nwunye eletrik na-ekpo ọkụ na njedebe na-ekpo ọkụ hà nhata nchikota nke ike eletrik ntinye na mmepụta oyi nke njedebe oyi, ma n'aka nke ọzọ, enwere ike ikwubi na mmepụta oyi Qc hà nhata dị iche n'etiti okpomọkụ na-apụta site na njedebe ọkụ na ntinye ike eletrik.

Qh=P+Qc

Qc=Qh-P

Usoro mgbako nke kacha ike jụrụ oyi thermoelectric

A.1 Mgbe okpomọkụ na njedebe na-ekpo ọkụ Th bụ 27 ℃ ± 1 ℃, okpomọkụ dị iche bụ △T = 0, na I = Imax.

A na-agbakọ ike jụrụ oyi kacha elu Qcmax (W) dịka usoro (1): Qcmax=0.07NI.

Ebe N - logarithm nke thermoelectric ngwaọrụ, m - kacha okpomọkụ dị iche ugbu a nke ngwaọrụ (A).

A.2 Ọ bụrụ na okpomọkụ nke na-ekpo ọkụ elu bụ 3 ~ 40 ℃, kacha jụrụ ike Qcmax (W) kwesịrị mezie dị ka usoro (2).

Qcmax = Qcmax×[1+0.0042(Th--27)]

(2) Na usoro: Qcmax - ọkụ elu okpomọkụ Th = 27 ℃ ± 1 ℃ kacha jụrụ ike (W), Qcmax∣Th - ọkụ elu okpomọkụ Th - kacha jụrụ ike (W) na tụrụ okpomọkụ si 3 ka 40 ℃
