Imikorere yo gukonjesha hakoreshejwe thermoelectric

Imikorere yo gukonjesha hakoreshejwe thermoelectric:

Mbere yo gukoresha uburyo bwo gukonjesha bwa thermoelectric, kugira ngo dusobanukirwe neza imikorere yabwo, mu by'ukuri, impera ikonje ya module ya peltier, module za thermoelectric, ifata ubushyuhe buturutse mu nkengero, hari ebyiri: imwe ni ubushyuhe bwa joule Qj; Indi ni ubushyuhe bwo gutwara umuriro Qk. Umuriro unyura imbere mu gice cya thermoelectric kugira ngo utange ubushyuhe bwa joule, kimwe cya kabiri cy'ubushyuhe bwa joule cyoherezwa ku mpera ikonje, ikindi gice cyoherezwa ku mpera ishyushye, kandi ubushyuhe bwo gutwara umuriro bwoherezwa kuva ku mpera ishyushye kugera ku mpera ikonje.

Umusaruro ukonje Qc=Qπ-Qj-Qk

= (2p-2n).Tc.I-1/2j²R-K (Th-Tc)

Aho R ihagarariye uburinzi bwose bwa pair na K ikaba ari ubushyuhe bwose butwara.

Ubushyuhe bwavuye ku gice gishyushye Qh=Qπ+Qj-Qk

= (2p-2n).Th.I+1/2I²R-K (Th-Tc)

Bigaragara muri formula ebyiri zavuzwe haruguru ko ingufu z'amashanyarazi zinjira ari itandukaniro riri hagati y'ubushyuhe bukurwa n'inkombe ishyushye n'ubushyuhe bwinjizwa n'inkombe ikonje, aribwo bwoko bwa "pompe y'ubushyuhe":

Qh-Qc=I²R=P

Dukurikije formula yavuzwe haruguru, dushobora kwemeza ko ubushyuhe Qh butangwa n'amashanyarazi ku mpera ishyushye bungana n'igiteranyo cy'ingufu z'amashanyarazi zinjira n'umusaruro ukonje w'impera ikonje, kandi ku rundi ruhande, dushobora kwemeza ko umusaruro ukonje Qc ungana n'itandukaniro riri hagati y'ubushyuhe butangwa n'impera ishyushye n'ingufu z'amashanyarazi zinjira.

Qh=P+Qc

Qc=Qh-P

Uburyo bwo kubara imbaraga ntarengwa zo gukonjesha amashanyarazi

A.1 Iyo ubushyuhe ku mpera y'ubushyuhe bwa Th ari 27℃±1℃, itandukaniro ry'ubushyuhe ni △T=0, na I=Imax.

Ingufu ntarengwa zo gukonjesha Qcmax(W) zibarwa hakurikijwe formula (1): Qcmax=0.07NI

Aho N — logarithm y'igikoresho gikoresha amashanyarazi, I — itandukaniro ntarengwa ry'ubushyuhe bw'igikoresho (A).

A.2 Niba ubushyuhe bw'ubuso bushyushye ari 3 ~ 40℃, imbaraga ntarengwa zo gukonjesha Qcmax (W) zigomba gukosorwa hakurikijwe formula (2).

Qcmax = Qcmax×[1+0.0042(Th--27)]

(2) Muri formula: Qcmax — ubushyuhe bw'ubuso bushyushye Th=27℃±1℃ imbaraga ntarengwa zo gukonjesha (W), Qcmax∣Th — ubushyuhe bw'ubuso bushyushye Th — imbaraga ntarengwa zo gukonjesha (W) ku bushyuhe bwapimwe kuva kuri 3 kugeza kuri 40℃
