He Introduction To Thermoelectric cooling module
ʻO ka ʻenehana Thermoelectric kahi ʻenehana hoʻokele wela e pili ana i ka hopena Peltier. Ua ʻike ʻia e JCA Peltier i ka makahiki 1834, pili kēia ʻano i ka hoʻomehana ʻana a i ʻole ka hoʻoluʻu ʻana o ka hui ʻana o nā mea thermoelectric ʻelua (bismuth a telluride) ma ke kahe ʻana i kēia manawa ma ka hui. I ka wā o ka hana, kahe pololei ke au ma ka module TEC e hoʻoneʻe ʻia ka wela mai kekahi ʻaoʻao a i kekahi. Ke hana ʻana i kahi ʻaoʻao anu a wela. Inā hoʻohuli ʻia ka ʻaoʻao o ke au, hoʻololi ʻia nā ʻaoʻao anu a me ka wela. Hiki ke hoʻololi ʻia kona mana hoʻoluʻu ma ka hoʻololi ʻana i kāna ʻano hana. ʻO kahi mea hoʻomaʻamaʻa maʻamau maʻamau (Figure. 1) ʻelua mau papa seramika me ka p a me n-type semiconductor material (bismuth ,telluride) ma waena o nā papa seramika. Hoʻopili ʻia nā mea o nā mea semiconductor me ka uila ma ke ʻano a me ka thermally i ka like.
Thermoelectric cooling module, Peltier device, TEC modules hiki ke noʻonoʻo ʻia e like me ke ʻano o ka pāpaʻi ikaika wela, a ma muli o kona kaumaha maoli, ka nui a me ka wikiwiki o ka pane ʻana, kūpono loa ia e hoʻohana ʻia ma ke ʻano o nā ʻōnaehana hoʻomaha inbuilt (ma muli o ka palena o ka lewa). Me nā mea maikaʻi e like me ka hana mālie, ka haki ʻana, ke kūpaʻa haʻalulu, ʻoi aku ka maikaʻi o ke ola a me ka maʻalahi o ka mālama ʻana, ʻo ka thermoelectric cooling module, peltier device, TEC modules he ākea ākea i nā kahua o ka pūʻali koa, mokulele, aerospace, lāʻau lapaʻau, pale ʻana i ka maʻi maʻi, nā mea hoʻokolohua, nā huahana mea kūʻai (wai hoʻomaʻamaʻa, hoʻoluʻu kaʻa, pahu hau hokele, wai hoʻoluʻu, a me nā mea ʻē aʻe.
I kēia lā, ma muli o kona kaumaha haʻahaʻa, liʻiliʻi liʻiliʻi a i ʻole ka liʻiliʻi a me ke kumu kūʻai haʻahaʻa, hoʻohana nui ʻia ka thermoelectric cooling i ka lāʻau lapaʻau, lāʻau lapaʻau equiment, mokulele, aerospace, pūʻali koa, spectrocopy system, a me nā huahana pāʻoihana (e like me ka dispenser wai wela a me ke anuanu, nā pahu hau portable, carcooler a pēlā aku)

| I | Ke hana nei i kēia manawa i ka module TEC (ma Amps) |
| Imax | ʻO ke ʻano hana e hana i ka ʻokoʻa wela kiʻekiʻe loa △Tmax(ma Amps) |
| Qc | Ka nui o ka wela e hiki ke komo ma ka ʻaoʻao anuanu o ka TEC (ma Watts) |
| Qmax | ʻO ka nui o ka wela e hiki ke komo ma ka ʻaoʻao anu. Hana ʻia kēia ma I = Imaxa i ka manawa Delta T = 0. (i Watts) |
| Twela | Ka wela o ka ʻaoʻao wela i ka wā e hoʻohana ana ka module TEC (ma °C) |
| Tanu | Ka wela o ka maka ʻaoʻao anu i ka wā e hana ana ka module TEC (ma °C) |
| △T | ʻO ka ʻokoʻa ma waena o ka ʻaoʻao wela (Th) a me ka aoao anu (Tc). Delta T = Th-Tc(i ka °C) |
| △Tmax | ʻO ka ʻokoʻa kiʻekiʻe loa o ka wela e hiki ke loaʻa i kahi module TEC ma waena o ka ʻaoʻao wela (Th) a me ka aoao anu (Tc). Loaʻa kēia (ka hiki ke hoʻoluʻu kiʻekiʻe) ma I = Imaxa me Qc= 0. (i ka °C) |
| Umax | Ka lako uila ma I = Imax(ma Volts) |
| ε | ʻO ka pono hoʻoluʻu ʻana o ka module TEC (%) |
| α | Seebeck coefficient o ka mea thermoelectric (V/°C) |
| σ | Ka helu uila o ka mea thermoelectric (1/cm·ohm) |
| κ | ʻO ka hoʻoheheʻe wela o nā mea thermoelectric (W/CM·°C) |
| N | Ka helu o ka mea thermoelectric |
| Iεmax | Hoʻopili ʻia kēia manawa i ka ʻaoʻao wela a me ka mahana ʻaoʻao kahiko o TEC module kahi waiwai kikoʻī a pono e loaʻa ka ʻoi loa o ka pono (ma Amps) |
Hoʻokomo i nā palapala noi i ka module TEC
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)
