1. Hakanya mojaro oa mocheso

Moroalo oa mocheso o bolela bongata ba mocheso o hlokang ho tlosoa ho theola mocheso oa sepheo sa ho pholisa ho ea boemong bo boletsoeng tlas'a tikoloho e itseng ea mocheso, 'me yuniti e le W (watt). Meroalo ea mocheso e kenyelletsa haholo-holo meroalo e sebetsang, meroalo e sa sebetseng, le metsoako ea eona. Moroalo oa mocheso o sebetsang ke mojaro oa mocheso o hlahisoang ke sepheo sa ho pholisa ka bosona. Moroalo oa mocheso o sa sebetseng ke mojaro oa mocheso o bakoang ke mahlaseli a kantle, convection le conduction. Foromo ea ho bala mojaro o sebetsang

Qeto = V2/R = VI = I2R;

Qactive = Moroalo o matla oa mocheso (W);

V = Motlakase o sebediswang ho sepheo sa sehatsetsi (V);

R = Ho hanyetsa sepheo sa ho futhumatsa;

I = Motlakase o phallang ka har'a sepheo se pholileng (A)

Moroalo o futhumatsang ke mojaro o futhumatsang o fetisetsoang nthong e reriloeng ka mahlaseli a motlakase. Foromo ea lipalo:

Qrad = F es A (Tamb4 – Tc4);

Qrad = Moroalo oa mocheso o matla (W);

F = ntlha ya sebopeho (boleng bo bobe ka ho fetisisa = 1);

e = ho ntša metsi (boleng bo bobe ka ho fetisisa = 1);

s = Stefan-Boltzmann e sa fetoheng (5.667 X 10-8W/m² k4);

A = Sebaka sa ho phodisa (m²);

Tamb = Mocheso o Tebileng (K);

Tc = TEC – Mocheso o batang (K).

Moroalo oa mocheso o feto-fetohang ke mojaro oa mocheso o fetisetsoang ka tlhaho ke mokelikeli o fetang holim'a ntho e reretsoeng ho tsoa kantle. Foromo ea lipalo ke:

Qconv = hA (Tair – Tc);

Qconv = Moroalo oa mocheso o feto-fetohang (W)

h = Koefficient ea phetisetso ea mocheso e feto-fetohang (W/m² °C) (boleng bo tloaelehileng ba sefofane sa metsi sepakapakeng se le seng se tloaelehileng) = 21.7 W/m² °C;

A = Sebaka sa bokaholimo (m²);

Tair = Mocheso oa tikoloho (°C);

Tc = Mocheso o batang (°C);

Moroalo o tsamaisang mocheso ke mojaro o fetisetswang ho tloha kantle ka dintho tse hokahaneng tse hodima ntho e rerilweng. Foromo ya ho bala ke:

Qcond =k A DT/L;

Qcond = Moroalo oa mocheso o fetiselitsoeng (W);

k = Ho tsamaisa mocheso ha thepa e tsamaisang mocheso (W/m °C);

A = Sebaka se nang le karolo e tšekaletseng ea thepa e tsamaisang mocheso (m²);

L = Bolelele ba tsela ea ho tsamaisa mocheso (m)

DT = Phapang ea mocheso oa tsela ea ho tsamaisa mocheso (°C) (hangata e bolela mocheso o potolohileng kapa mocheso oa ho futhumatsa mocheso ntle le mocheso oa pheletso e batang.)

Bakeng sa mojaro o kopaneng oa mocheso oa convection le conduction, foromo ea lipalo ke:

Q e sa sebetseng = (A x DT)/(x/k + 1/h);

Qpassive = Moroalo oa mocheso (W);

A = Sebaka sohle sa bokaholimo ba khetla (m2);

x = Botenya ba lera la ho thibela ho ruruha (m)

k = Ho tsamaisa mocheso ka mocheso o kenang kahare (W/m °C);

h = Koefficient ea phetisetso ea mocheso e feto-fetohang (W/m² °C)

DT = Phapang ea mocheso (°C).

2. Bala kakaretso ea mojaro oa mocheso

Mohatong oa pele, re ka bala kakaretso ea mocheso o felletseng oa sepheo sa sehatsetsing.

A re re morerong oa sebele, mojaro o sebetsang oa mocheso ke 8W, mojaro o khanyang oa mocheso ke 0.2W, mojaro o potolohang oa mocheso ke 0.8W, mojaro o tsamaisang mocheso ke 0W, 'me kakaretso ea mojaro oa mocheso ke 9W.

3. Hlalosa mocheso

Hlalosa mocheso oa pheletso e chesang, mocheso oa pheletso e batang le phapang ea mocheso oa sehatsetsing oa leqephe la sehatsetsi. A re re morerong oa 'nete, mocheso o potolohileng ke 27°C, mocheso o reretsoeng ho pholisa ke -8°C, 'me phapang ea mocheso oa ho pholisa DT=35°C

Ha re nahana hore kakaretso ea mocheso oa sepheo sa ho pholisa e hakanngoa hore ke 9W ho latela khakanyo e fetileng, Qmax e ntle ka ho fetisisa e ka fumanoa e le 9/0.25=36W, 'me Qmax e phahameng ka ho fetisisa e ka fumanoa e le 9/0.45=20. Batla kataloge ea lihlahisoa tsa Beijing Huimao Cooling Equipment Co., Ltd bakeng sa li-module tsa thermoelectric cooling, li-module tsa peltier, lisebelisoa tsa peltier, li-module tsa peltier.TEC 'me u fumane lihlahisoa tse nang le Qmax e tlohang ho 20 ho isa ho 36.
