Peltier modul: nkọwa

Thermocouples (Peltier modul) arụ ọrụ na ụkpụrụ nke thermocouple abụghị mmetụta - ọdịdị nke okpomọkụ dị iche mgbe eletrik aga.

Olee otú a Peltier mmewere?

Nnọọ nanị tinye a Peltier modul, ụkpụrụ nke nke bụ na emission ma ọ bụ absorption nke okpomọkụ n'oge kọntaktị nke dị iche iche ihe site na-agafe therethrough a ugbu a. Njupụta nke ume agbanwe oge nke electrons tupu mgbe kọntaktị bụ dị iche iche. Ọ bụrụ na mmepụta bụ obere, ọ pụtara na e nwere ike igbanye okpomọkụ. Mgbe electrons na-decelerated na kọntaktị site na electric ubi, ha nweta kinetic ike na lattice, Okpomoku ya. Ọ bụrụ na ha na-ngwa ngwa na, okpomọkụ na-etinye obi gị dum. Nke a bụ n'ihi na eziokwu na akụkụ nke ike-e si crystal lattice na ya jụrụ-ewe ebe.

Ruo n'ókè dị ukwuu, nke a onu bụ pụta ụwa Semiconductors, n'ihi na oké ihe dị iche n'etiti ebubo.

Peltier modul, ojiji nke nke bụ isiokwu nke anyị nyochaa, na-eji ike a thermoelectric jụrụ ngwaọrụ (TEM). The mfe nke mejupụtara abụọ okporo ọkụ p- na n-ụdị, serially ejikọrọ via ọla kọpa kọntaktị.

Ọ bụrụ na electrons ịkwaga si okporo ọkụ "p" na "n", mbụ mgbanwe site na metal crosspiece ha recombine na ntọhapụ nke ike. The ọzọ mgbanwe site okporo ọkụ "p" na ọla kọpa na-eduzi ya na-esonyere "ndinyanade mbịne" nke electrons site nkwụsị site electric ubi. Usoro a na-eduga ná absorption nke ike na jụrụ nke ebe gburugburu kọntaktị. N'otu aka ahụ, e nwere ndị Filiks na ndị a na ikwu n'ụzọ.

Mgbe ọnọdụ nke kpo oku na obi jụrụ kọntaktsị na dị iche iche yiri ụgbọ elu na-bara uru, mmejuputa iwu nke usoro. Semiconductors na-mere nke selenium, bismuth, antimony na tellurium. Peltier modul accommodates a ọnụ ọgụgụ buru ibu nke thermocouples enịm n'etiti seramiiki efere nitride ma ọ bụ aluminum oxide.
