Ukusebenza kwe-thermoelectric cooling

I-Thermoelectric COOLING CATUCATION CALISE:

Ngaphambi kokusebenzisa ukupholisa kwe-thermoelectric, ukuze uphinde uqonde ukusebenza kwawo, eqinisweni, ama-module amakhaza, amamojula we-thermoelectric, amunca ukushisa okuzungezile, kukhona ama-Joule Heat QJ; Enye indlela yokushisa ye-versiction. Ukudlula kwamanje ngaphakathi kwento ye-thermoelectric ukukhiqiza ukushisa kwe-jeule, uhhafu wokushisa kwejuule udluliselwa ekugcineni okubandayo, enye ingxenye idluliselwa endaweni eshisayo, futhi ukushisa okuvuthayo kudluliswa kusuka ekugcineni okushisayo kuya emakhazeni qeda.

Ukukhiqizwa Okubandayo QC = Qπ-QJ-QK

= (2p-2n) .tc.i-1 / 2J²r-K (Th-TC)

Lapho r imele ukumelana okuphelele kwe-pair ne-K Ingabe ukuvumelanisa okuphelele okushisayo.

Ukushisa okuhlanjululwe kusuka ekugcineni okushisayo QH = Qπ + QJ-QJ-QK

= (2p-2n) .th + 1 / 2i²r-K (Th-TC)

Kungabonakala kusuka kumafomula amabili angenhla wokuthi amandla kagesi wokufaka anomehluko ncamashi phakathi kokushisa okuhlaselwe ukuphela okushisayo nokushisa okudonsa ngokuphela okubandayo, okuwuhlobo lwe- "pump yokushisa":

Qh-qc = i²r = P

Kusuka kufomula engenhla, kungaphethwa ngokuthi ukushisa kwe-QH kukhishwe ngumbhangqwana kagesi endaweni eshisayo kulingana nenani lamandla kagesi wokufaka, futhi ngakolunye uhlangothi, kungaphethwa ngokuthi Ukukhishwa okubandayo kwe-QC kulingana nomehluko phakathi kokushisa okukhishwe ukuphela okushisayo kanye namandla kagesi wokufaka.

Qh = p + qc

Qc = qh-p

Indlela yokubala yamandla wokupholisa we-thermoelectric aphezulu

A.1 Lapho amazinga okushisa esiphelweni esishisayo th uneminyaka engama-27

I-QCMax (W) ephezulu kakhulu ibalwa ngokuya ngefomula (1): qcmax = 0.07NI

Lapho n - i-logarithm yedivaysi ye-thermoelectric, i - ukumelana okuphezulu kokumelana kwamanje kwedivayisi (a).

A.2 Uma izinga lokushisa lendawo eshisayo lingu-3 ~ 40 ℃, i-QCMax ephezulu kakhulu ye-QCMAX (W) kufanele ilungiswe ngokusho kwefomula (2).

QCMAX = QCMAX × 1 + 0.0042 (th - 27)]
