Thermoelectric kutonhora kuita

Thermoelectric kutonhora kuita kuverenga:

Usati washandisa iyo thermoelectric cooling, kuti uwedzere kunzwisisa kushanda kwayo, chaizvoizvo, kupera kunotonhora kwepeltier module, thermoelectric modules, inotora kupisa kubva kumativi akapoteredza, kune maviri: imwe ijoule kupisa Qj; Imwe yacho ndeye conduction kupisa Qk. Ikozvino inopfuura nemukati me thermoelectric element kuti ibudise kupisa kwejoule, hafu yejoule inopisa inotapurirwa kumagumo anotonhora, imwe hafu inoendeswa kumagumo anopisa, uye kupisa kwekufambisa kunoparidzirwa kubva kunopisa kusvika kunotonhora.

Cold production Qc=Qπ-Qj-Qk

= (2p-2n).Tc.I-1/2j²R-K (Th-Tc)

Apo R inomiririra kupikisa kwese kwepeya uye K ndiyo yakazara kupisa conductivity.

Kupisa kwakabviswa kubva kunopisa kunopisa Qh=Qπ+Qj-Qk

= (2p-2n).Th.I+1/2I²R-K (Th-Tc)

Zvinogona kuoneka kubva kune maviri mafomula ari pamusoro apa kuti simba remagetsi rekuisa ndiwo chaiwo mutsauko pakati pekupisa kwakabviswa nekupisa kunopisa uye kupisa kunotorwa nekupera kunotonhora, inova rudzi rwe "heat pombi" :

Qh-Qc=I²R=P

Kubva pane chirevo chiri pamusoro apa, zvinogona kugumiswa kuti kupisa kweQh kunobudiswa nevakaroorana vemagetsi pamagumo anopisa akaenzana nehuwandu hwekupinza simba remagetsi uye kutonhora kunobuda kwekupedzisira kunotonhora, uye zvakasiyana, zvinogona kugumiswa kuti iyo inotonhora yakabuda Qc yakaenzana nemusiyano pakati pekupisa kunobudiswa nemhepo inopisa uye simba remagetsi rinopinza.

Qh=P+Qc

Qc=Qh-P

Kuverengera nzira yeakanyanya thermoelectric kutonhora simba

A.1 Kana tembiricha panopisa Th i 27℃±1℃, musiyano wetembiricha uri △T=0, uye I=Imax.

Iyo yakanyanya kutonhora simba Qcmax(W) inoverengerwa zvinoenderana neformula (1): Qcmax=0.07NI

Ipo N - logarithm ye thermoelectric mudziyo, I - yakanyanya tembiricha mutsauko wazvino wemudziyo (A).

A.2 Kana tembiricha yenzvimbo inopisa iri 3 ~ 40 ℃, iyo yakanyanya kutonhora simba Qcmax (W) inofanira kugadziriswa maererano nefomati (2).

Qcmax = Qcmax×[1+0.0042(Th--27)]

(2) Mune fomula: Qcmax - kupisa kwepamusoro tembiricha Th=27℃±1℃ yakanyanya kutonhora simba (W), Qcmax∣Th - inopisa pamusoro tembiricha Th - yakanyanya kutonhora simba (W) pakuyerwa tembiricha kubva 3 kusvika 40 ℃
