Nhanganyaya kuThermoelectric kutonhora module
Thermoelectric tekinoroji ndeye inoshanda yekupisa manejimendi nzira yakavakirwa paPeltier maitiro.Yakawanikwa naJCA Peltier muna 1834, chiitiko ichi chinosanganisira kudziyisa kana kutonhora kwemusanganiswa wezvinhu zviviri zvethermoelectric (bismuth uye telluride) kuburikidza nekupfuura ikozvino kuburikidza nejunction.Panguva yekushanda, ikozvino yakananga inoyerera kuburikidza neTEC module inokonzera kupisa kutamiswa kubva kune rumwe rutivi kuenda kune rumwe.Kugadzira rutivi runotonhora uye runopisa.Kana kutungamirirwa kwezvino kuchinjwa, kutonhora uye kupisa mativi kunochinjwa.Simba rayo rekutonhodza zvakare rinogona kugadziriswa nekuchinja kushanda kwayo ikozvino.Chinotonhodza chinhanho chimwe chete (Mufananidzo. 1) chine mahwendefa maviri eceramic ane p uye n-mhando semiconductor zvinhu (bismuth,telluride) pakati pemahwendefa eceramic.Izvo zvinhu zve semiconductor zvinhu zvakabatanidzwa nemagetsi munhevedzano uye thermally mune parallel.
Thermoelectric cooling module,Peltier device,TEC modules inogona kutariswa semhando yepombi yakasimba-nyika inopisa simba, uye nekuda kwehuremu hwayo chaihwo, saizi uye chiyero chekuita, yakakodzera kwazvo kushandiswa sechikamu chekutonhora kwemukati. masisitimu (nekuda kwekuganhurwa kwenzvimbo).Nezvakanakira senge kunyarara kushanda, shatter proof, shock resistance, hupenyu hurefu hunobatsira uye kugadzirisa zviri nyore, yemazuva ano thermoelectric cooling module,peltier device,TEC modules ine huwandu hwakasiyana hwekushandisa muminda yemidziyo yemauto, ndege, ndege, kurapwa, denda. kudzivirira, midziyo yekuedza, zvigadzirwa zvevatengi (mvura inotonhorera, inotonhorera mota, firiji yehotera, inotonhorera yewaini, inotonhorera yemunhu mini, inotonhorera & kupisa yekurara pad, nezvimwe).
Nhasi, nekuda kwehuremu hwayo hushoma, hukuru hudiki kana huwandu uye mutengo wakaderera, thermoelectric kutonhora inoshandiswa zvakanyanya mukurapa, mishonga yemagetsi, ndege, aerospace, mauto, spectrocopy masisitimu, uye zvigadzirwa zvekutengesa (sezvinopisa & inotonhora mvura inoburitsa, inotakurika mafiriji, carcooler uye zvichingodaro)
| Parameters | |
| I | Kushanda Parizvino kune TEC module (muAmps) |
| Imax | Kushanda Parizvino kunoita kuti musiyano mukuru wekushisa △Tmax(muAmps) |
| Qc | Huwandu hwekupisa hunogona kunyudzwa padivi rinotonhora kumeso kweTEC (muWatts) |
| Qmax | Kunyanya huwandu hwekupisa hunogona kubatwa padivi rinotonhora.Izvi zvinoitika pana I = Imaxuye apo Delta T = 0. (muWatts) |
| Tinopisa | Tembiricha yedivi rinopisa kumeso kana TEC module ichishanda (mu ° C) |
| Tkutonhora | Tembiricha yekutonhora yedivi kumeso kana TEC module ichishanda (mu ° C) |
| △T | Musiyano wekushisa pakati perutivi rwunopisa (Th) uye rutivi runotonhora (Tc)Delta T = Th-Tc(mu °C) |
| △Tmax | Musiyano mukuru wetembiricha iyo TEC module inogona kuwana pakati penzvimbo inopisa (Th) uye rutivi runotonhora (Tc)Izvi zvinoitika (Maximum cooling capacity) paI = Imaxuye qc= 0. (mu °C) |
| Umax | Magetsi anopihwa paI = Imax(muVolts) |
| ε | TEC module kutonhora kutonhora (%) |
| α | Seebeck coefficient of thermoelectric material (V/°C) |
| σ | Magetsi coefficient of thermoelectric material (1/cm·ohm) |
| κ | Thermo conductivity ye thermoelectric material (W/CM·°C) |
| N | Nhamba ye thermoelectric element |
| Iεmax | Yazvino yakabatanidzwa kana iyo inopisa side uye yekare tembiricha yeTEC module iri kukosha kwakatarwa uye yaida kuwana iyo Maximum kunyatsoshanda (muAmps) |
Kuunzwa kweMafomu ekushandisa kuTEC module
Qc= 2N[α(Tc+273)-LI²/2σS-κs/Lx(Th- Tc)]
△T= [ Iα(Tc+273)-LI/²2σS] / (κS/L + I α]
U = 2 N [ IL /σS +α(Th- Tc)]
ε = Qc/UI
Qh= Qc + IU
△Tmax= Th+ 273 + κ/σα² x [ 1-√2σα²/κx (Th+273) + 1]
Imax =κS/ Lαx [√2σα²/κx (Th+273) + 1-1]
Iεmax =ασS (Th- Tc) / L (√1+0.5σα²(546+ Th- Tc)/ κ-1)
