Waxqabadka qaboojinta kulaylka

Xisaabinta waxqabadka qaboojinta kulaylka:

Kahor intaadan codsan qaboojinta heerkulbeegyada, si loo sii fahmo waxqabadkeeda, dhab ahaantii, dhamaadka qabow ee moduleka peltier, modules thermoelectric, waxay nuugaan kulaylka hareeraha, waxaa jira laba: mid waa kulaylka joule Qj; Midda kale waa kulaylka conduction Qk. Xilligan waxa uu dhex maraa qaybta kuleyliyaha kuleyliyaha si uu u soo saaro kulaylka joule, kala bar kulaylka joule waxaa loo gudbiyaa dhamaadka qabow, qeybta kalena waxaa loo gudbiyaa dhamaadka kulaylka, kulaylka korantada waxaa laga soo qaadaa dhamaadka kulul ilaa dhamaadka qabow.

Soo saarista qabow Qc=Qπ-Qj-Qk

= (2p-2n).Tc.I-1/2j²R-K (Th-Tc)

Meesha R ay ka dhigan tahay wadarta iska caabbinta lamaanaha iyo K waa wadarta kulaylka.

Kulaylku wuxuu ka soo dareeray dhamaadka kulul Qh=Qπ+Qj-Qk

= (2p-2n).Th.I+1/2I²R-K (Th-Tc)

Waxaa laga arki karaa labada hab ee kor ku xusan in tamarta korontadu ay tahay faraqa u dhexeeya kulaylka uu kufsado dhamaadka kulul iyo kulaylka uu nuugo dhamaadka qabow, kaas oo ah nooc ka mid ah "bamka kulaylka" :

Qh-Qc=I²R=P

Marka la eego qaacidada sare, waxaa lagu soo gabagabeyn karaa in kulaylka Qh ee ay ka soo baxaan lammaanaha korontadu marka uu dhammaado kulaylku uu la mid yahay wadarta awoodda korontadu ku shubto iyo ka soo baxa qabowga dhamaadka qabowga, taas beddelkeeda, waxa la soo gunaanadi karaa in soo-saarka qabow ee Qc ​​uu la mid yahay farqiga u dhexeeya kulaylka ka dhalanaya dhammaadka kulaylka

Qh=P+Qc

Qc=Qh-P

Habka xisaabinta awoodda qaboojinta heerkulbeegga ugu sarreeya

A.1 Marka heerkulka dhamaadka kulul Th uu yahay 27℃±1℃, heerkulku waa △T=0, iyo I=Imax.

Awoodda qaboojinta ugu badan Qcmax(W) waxaa loo xisaabiyaa si waafaqsan qaacidada (1): Qcmax=0.07NI

Halka N - logarithm ee qalabka kuleyliyaha, I - farqiga heerkulka ugu sarreeya ee hadda ee qalabka (A).

A.2 Haddii heerkulka dusha kulul yahay 3 ~ 40 ℃, awoodda qaboojinta ugu badan ee Qcmax (W) waa in la saxo sida ku cad formula (2).

Qcmax = Qcmax×[1+0.0042(Th--27)]

(2) In formula: Qcmax - heerkulka dusha kulul Th = 27 ℃ ± 1 ℃ awoodda qaboojinta ugu badnaan (W), Qcmax
