Ts'ebetso ea ho futhumatsa ea thermoelectric

Palo ea ts'ebetso ea ho pholisa ea Thermoelectric:

Pele o sebelisa pholiso ea thermoelectric, ho utloisisa haholoanyane ts'ebetso ea eona, ha e le hantle, pheletso e batang ea mojule oa peltier, li-module tsa thermoelectric, li monya mocheso ho tsoa ho tse potolohileng, ho na le tse peli: e 'ngoe ke joule mocheso Qj; E 'ngoe ke conduction mocheso Qk. Hona joale e feta ka hare ho karolo ea thermoelectric ho hlahisa mocheso oa joule, halofo ea mocheso oa joule e fetisetsoa pheletsong e batang, halofo e 'ngoe e fetisetsoa pheletsong e chesang,' me mocheso oa conduction o fetisoa ho tloha pheletsong e chesang ho ea qetellong ea serame.

Tlhahiso e batang Qc=Qπ-Qj-Qk

= (2p-2n).Tc.I-1/2j²R-K (Th-Tc)

Moo R e emelang khanyetso e felletseng ea para le K ke kakaretso ea mocheso oa mocheso.

Mocheso o tlositsoe pheletsong e chesang Qh=Qπ+Qj-Qk

Ho ka bonoa ho tsoa ho liforomo tse peli tse kaholimo hore matla a motlakase a kentsoeng hantle ke phapang lipakeng tsa mocheso o felisitsoeng ke pheletso e chesang le mocheso o nkuoang ke pheletso e batang, e leng mofuta oa "pompo ea mocheso" :

Mokhoa oa ho bala oa matla a phahameng a ho futhumatsa a thermoelectric

A.1 Ha mocheso qetellong ea mocheso oa Th e le 27℃±1℃, phapang ea mocheso ke △T=0, le I=Imax.

Matla a phahameng a ho pholisa Qcmax(W) a baloa ho latela foromo (1): Qcmax=0.07NI

Moo N — logarithm ea sesebediswa thermoelectric, I - palo e kahodimodimo mocheso phapang hona joale ea sesebediswa (A).

A.2 Haeba mocheso oa sebaka se chesang o le 3 ~ 40 ℃, matla a mangata a ho pholile a Qcmax (W) a lokela ho lokisoa ho ea ka foromo (2).

Qcmax = Qcmax×[1+0.0042(Th--27)]
