1. Mee atụmatụ ibu okpomọkụ

Ibu okpomọkụ na-ezo aka na oke okpomọkụ nke a ga-ewepụ iji wedata okpomọkụ nke ihe mgbaru ọsọ oyi ruo ọkwa akọwapụtara n'okpuru gburugburu okpomọkụ ụfọdụ, ebe nkeji ahụ bụ W (watt). Ibu okpomọkụ na-agụnyekarị ibu ọrụ, ibu na-agafe agafe, na njikọta ha. Ibu okpomọkụ na-arụ ọrụ bụ ibu okpomọkụ nke ihe mgbaru ọsọ oyi n'onwe ya na-emepụta. Ibu okpomọkụ na-agafe agafe bụ ibu okpomọkụ nke radieshon mpụga, convection na conduction kpatara. Usoro ngụkọ ibu na-arụ ọrụ

Ngwakọta = V2/R = VI = I2R;

Qaactive = Ibu okpomọkụ na-arụ ọrụ (W);

V = Voltaji etinyere na ihe mgbaru ọsọ friji (V);

R = Nguzogide nke ihe mgbaru ọsọ nke friji;

I = Ọkụ na-agafe ihe mgbaru ọsọ oyi (A)

Ibu okpomọkụ na-enwu enwu bụ ibu okpomọkụ e bufere na ihe a na-elekwasị anya site na radieshon elektrọnik. Usoro ngụkọ:

Qrad = F es A (Tamb4 - Tc4);

Qrad = Ibu okpomọkụ na-enwu enwu (W);

F = ihe ọdịdị (uru kacha njọ = 1);

e = mmịpụta (uru kacha njọ = 1);

s = Stefan-Boltzmann na-agbanweghi agbanwe (5.667 X 10-8W/m² k4);

A = Mpaghara elu jụrụ oyi (m²);

Tamb = Okpomọkụ Gburugburu (K);

Tc = TEC – Okpomọkụ njedebe oyi (K).

Ibu okpomọkụ convective bụ ibu okpomọkụ ebufe site na mmiri mmiri na-agafe n'elu ihe ebumnuche site na mpụga. Usoro ngụkọ bụ:

Qconv = hA (Tair – Tc);

Qconv = Ibu Okpomọkụ Convective (W)

h = Ọnụọgụ mbufe okpomọkụ Convective (W/m ² °C) (uru nkịtị nke mbara mmiri n'otu ikuku ọkọlọtọ) = 21.7 W/m ² °C;

A = Mpaghara elu (m²);

Tair = Ọnọdụ okpomọkụ (°C);

Tc = Okpomọkụ njedebe oyi (°C);

Ibu okpomọkụ na-eduzi bụ ibu okpomọkụ e si n'èzí bufee site na ihe kọntaktị dị n'elu ihe ebumnuche ahụ. Usoro ngụkọ bụ:

Qcond = k A DT/L;

Qcond = Ibu okpomọkụ ebufere (W);

k = Ọkwa okpomọkụ nke ihe na-eduzi okpomọkụ (W/m °C);

A = Mpaghara nkebi nke ihe na-eduzi okpomọkụ (m²);

L = Ogologo ụzọ mbugharị okpomọkụ (m)

DT = Ọdịiche okpomọkụ nke ụzọ mbugharị okpomọkụ (°C) (na-ezo aka na okpomọkụ gburugburu ma ọ bụ okpomọkụ sink okpomọkụ ma e wezụga okpomọkụ njedebe oyi.)

Maka njikọta okpomọkụ nke convection na conduction, usoro ngụkọ bụ:

Q passive = (A x DT)/(x/k + 1/h);

Qpassive = Ibu ọkụ (W);

A = Mkpokọta oke elu nke shei ahụ (m2);

x = Ọkpụrụkpụ nke oyi akwa mkpuchi (m)

k = Ọkwa okpomọkụ nke mkpuchi (W/m °C);

h = Ọnụọgụ mbufe okpomọkụ Convective (W/m ² °C)

DT = Ọdịiche okpomọkụ (°C).

2. Gbakọọ mkpokọta ibu okpomọkụ

Site na nzọụkwụ mbụ, anyị nwere ike ịgbakọ mkpokọta ibu okpomọkụ nke ihe mgbaru ọsọ friji.

Ka e were ya na ọrụ ahụ n'ezie, ibu okpomọkụ na-arụ ọrụ bụ 8W, ibu okpomọkụ na-enwu enwu bụ 0.2W, ibu okpomọkụ convective bụ 0.8W, ibu okpomọkụ na-eduzi bụ 0W, na mkpokọta ibu okpomọkụ bụ 9W.

3. Kọwaa okpomọkụ

Kọwaa ọdịiche dị n'etiti okpomọkụ dị n'akụkụ okpomọkụ, okpomọkụ dị n'akụkụ oyi na okpomọkụ dị n'akụkụ oyi. Ka e were ya na ọrụ ahụ, okpomọkụ dị n'akụkụ gburugburu bụ 27°C, okpomọkụ dị n'akụkụ oyi bụ -8°C, na ọdịiche dị n'etiti okpomọkụ dị n'akụkụ oyi DT = 35°C

Ọ bụrụ na a na-eme atụmatụ na mkpokọta oke okpomọkụ nke ihe achọrọ maka ime ka oyi dị 9W dabere na atụmatụ gara aga, enwere ike nweta Qmax kachasị mma dị ka 9/0.25=36W, yana Qmax kachasị dị ka 9/0.45=20. Chọọ katalọgụ ngwaahịa nke Beijing Huimao Cooling Equipment Co., Ltd maka modulu thermoelectric cooling, modulu peltier, ngwaọrụ peltier, ihe ndị ọzọ. modulu TEC wee chọta ngwaahịa nwere Qmax site na 20 ruo 36.
