Imikorere yo gukonjesha ya Thermoelectric

Kubara imikorere ya Thermoelectric:

Mbere yo gukoresha ubukonje bwa thermoelectric, kugirango urusheho gusobanukirwa imikorere yayo, mubyukuri, impera ikonje ya module ya peltier, moderi ya thermoelectric, ikurura ubushyuhe buturutse hafi, hariho bibiri: kimwe ni ubushyuhe bwa joule Qj; Ibindi ni ubushyuhe bwo gutwara Qk. Umuyoboro unyura imbere mubintu bya thermoelectric kugirango ubyare ubushyuhe bwa joule, kimwe cya kabiri cyubushyuhe bwa joule kwoherezwa kumpera ikonje, ikindi gice cyanduzwa kumpera ishyushye, naho ubushyuhe bwikwirakwizwa bwanduzwa kuva kumpera zishyushye kugera kumpera ikonje.

Umusaruro ukonje Qc = Qπ-Qj-Qk

= (2p-2n) .Tc.I-1 / 2j²R-K (Th-Tc)

Aho R igereranya imbaraga zose hamwe na K nubushuhe bwuzuye bwumuriro.

Ubushyuhe bwaturutse kumpera ishyushye Qh = Qπ + Qj-Qk

= (2p-2n) .Th.I + 1 / 2I²R-K (Th-Tc)

Birashobora kugaragara uhereye kuri formula ebyiri zavuzwe haruguru ko ingufu z'amashanyarazi zinjiza ari itandukaniro rwose hagati yubushyuhe bwakwirakwijwe nimpera zishyushye hamwe nubushyuhe bwinjizwa nimbeho ikonje, ni ubwoko bwa "pompe yubushyuhe":

Qh-Qc = I²R = P.

Duhereye kuri formula yavuzwe haruguru, dushobora kwanzura ko ubushyuhe Qh butangwa numugabo wamashanyarazi kumpera ishyushye bingana numubare wamashanyarazi yinjiza hamwe nubukonje bukonje bwimpera ikonje, kandi muburyo bunyuranye, dushobora kwemeza ko umusaruro ukonje Qc uhwanye no gutandukanya ubushyuhe butangwa numuriro ushushe nimbaraga zinjiza amashanyarazi.

Qh = P + Qc

Qc = Qh-P

Uburyo bwo kubara imbaraga ntarengwa zo gukonjesha

A.1 Iyo ubushyuhe kumpera ishyushye Th ni 27 ℃ ± 1 ℃, itandukaniro ryubushyuhe ni △ T = 0, na I = Imax.

Imbaraga ntarengwa zo gukonjesha Qcmax (W) ibarwa ukurikije formula (1): Qcmax = 0.07NI

Aho N - logarithm yigikoresho cya thermoelectric, I - itandukaniro ntarengwa ryubushyuhe bwibikoresho (A).

A.2 Niba ubushyuhe bwubuso bushyushye ari 3 ~ 40 ℃, imbaraga nyinshi zo gukonjesha Qcmax (W) zigomba gukosorwa ukurikije formula (2).

Qcmax = Qcmax × [1 + 0.0042 (Th - 27)]
