Ho ea ka litlhoko tsa ho khetha li-module tsa thermoelectric cooling, module ea TEC, likarolo tsa peltier.

Litlhoko tse akaretsang:

①, ho latela ts'ebeliso ea mocheso o teng oa Th ℃

(2) Mocheso o tlase oa Tc ℃ o fihletsoeng ke sebaka se pholileng kapa ntho

(3) Moroalo o tsebahalang oa mocheso Q (matla a mocheso a Qp, ho lutla ha mocheso Qt) W

Ho fanoe ka Th, Tc le Q, qubu e hlokahalang le palo ea liqubu li ka hakanngoa ho latela sebopeho sa mojule oa thermoelectric, sesebelisoa sa peltier.

Joalo ka mohloli o khethehileng o batang, mojule oa ho futhumatsa mocheso oa thermoelectric (TE cooler) o na le melemo le litšobotsi tse latelang ts'ebelisong ea tekheniki:

1, U se ke ua hloka sehatsetsi leha e le sefe, se ka sebetsa ka ho tsoelang pele, ha ho na mohloli oa tšilafalo ha ho na likarolo tse potolohang, li ke ke tsa hlahisa phello ea ho potoloha, ha ho na likarolo tse thellang ke sesebelisoa se tiileng, ha ho na ho thothomela, lerata, bophelo bo bolelele, ho kenya habonolo.

5, Tšebeliso e ka morao ea Thermoelectric Module, Pletier Module, Sesebelisoa sa Pletier ke phapang ea mocheso oa motlakase, jenereithara ea matla a Thermoelectric, jenereithara ea thermoelectric, module ea TEG hangata e loketse ho hlahisa matla a mocheso o tlase.

6, matla a karolo e le 'ngoe ea pholileng ea thermoelectric cooling module peltier module TE e nyenyane haholo, empa motsoako oa thermoelectric semiconductor N,P elements, ka mofuta o tšoanang oa letoto la lisebelisoa tsa thermoeletric, mokhoa o ts'oanang o kopantsoeng tsamaisong ea pholileng, matla a ka etsoa a maholo haholo, kahoo matla a pholileng a ka finyelloang ho likete tse seng kae tsa milliwatt.

7, Phapang ea mocheso oa li-module tsa peltier thermoelectric modules, ho tloha mocheso o motle oa 90 ℃ ho ea ho mocheso o fosahetseng 130 ℃ o ka finyelloa.

Thermoelectric cooling module Peltier module (Thermoelectric module) ke mosebetsi oa phepelo ea motlakase oa DC, o tlameha ho ba le phepelo ea motlakase e inehetseng.

1, phepelo ea motlakase ea DC. Molemo oa motlakase oa DC ke hore o ka sebelisoa ka ho toba ntle le phetoho, 'me bothata ke hore motlakase le hona joale li tlameha ho sebelisoa ho peltier module.peltier element, thermoelectric module,' me tse ling li ka rarolloa ka letoto le mokhoa o tšoanang oa li-module tsa TEC, likarolo tsa peltier, li-modules tsa thermoelectric.

2. Ac current. Ena ke phepelo ea motlakase e atileng haholo, e tlamehang ho lokisoa ho DC hore e sebelisoe ke thermoelectric cooling modlules TEC modules, peltier modules. Ho tloha ka Pletier module thermoelectric cooling module ke motlakase o tlase le sesebelisoa se phahameng sa hona joale, ho sebelisoa ha chelete ea pele, ho lokisoa, ho sefa, tse ling e le ho thusa ho sebelisa tekanyo ea mocheso, taolo ea mocheso, taolo ea hona joale joalo-joalo.

3, Hobane mojule oa Thermoelectric ke motlakase oa DC, sekhahla sa ripple sa phepelo ea motlakase se tlameha ho ba tlase ho 10%, ho seng joalo se na le tšusumetso e kholo ho phello ea pholileng.

4, Voltage e sebetsang le ea hajoale ea sesebelisoa sa peltier e tlameha ho fihlela litlhoko tsa sesebelisoa se sebetsang, mohlala: 12706 sesebelisoa, 127 ke thermoelectric module couples, PN ea logarithm ea motlakase ea banyalani, motlakase oa moeli oa ho sebetsa oa mojule oa thermoelectric V = logarithm ea banyalani ba motlakase × 0.11, 06 e lumelloa.

5, Matla a lisebelisoa tse futhumatsang tsa thermoelectric tse batang le phapanyetsano ea mocheso li tlameha ho khutlisetsoa mocheso oa kamore ha lipheletsong tse peli (ka kakaretso li nka metsotso e fetang 5 ho e phetha), ho seng joalo ho bonolo ho baka tšenyo ea potoloho ea elektroniki le ho phatloha ha lipoleiti tsa ceramic.

6, Potoloho ea elektroniki ea phepelo ea motlakase e pholileng ea thermoelectric e tloaelehile.
