Momwe mungasankhire ma module ozizira a thermoelectric (ma module a thermoelectric)?

Beijing Huimao Cooling Equipment Co., Ltd. yakhazikitsa ma modules ozizira a thermoelectric, thermoelectric modules, peltier elements, peltier devices, kuphatikizapo batch standard thermoelectric cooling modules, ma module a TEC ndi ma module apadera a thermoelectric, ma module a peltier, zinthu za peltier malinga ndi zosowa za makasitomala. Pali ma module a thermoelectric agawo limodzi, zida za peltier, ma module a TEC komanso ma module oziziritsa amitundu yambiri, ma module a thermoelectric, zoziziritsa kukhosi monga magawo awiri, magawo atatu mpaka asanu ndi limodzi. Thermoelectric cooling modules(thermoelectric modules,peltier elements) amagwiritsa ntchito mphamvu ya thermoelectric ya semiconductors. Mphamvu yolunjika ikadutsa mu thermocouple yopangidwa polumikiza zida ziwiri zosiyana za semiconductor motsatizana, kuzizira kozizira komanso kotentha kumatengera ndikutulutsa kutentha, zomwe zimawapanga kukhala chisankho chabwino pakugwiritsa ntchito panjinga kutentha. Sichifuna firiji iliyonse, imatha kugwira ntchito mosalekeza, ilibe gwero loipitsa komanso palibe magawo ozungulira, ndipo sichidzatulutsa mphamvu yozungulira. Kuphatikiza apo, ilibe magawo otsetsereka, imagwira ntchito popanda kugwedezeka kapena phokoso, imakhala ndi moyo wautali wautumiki ndipo ndiyosavuta kuyiyika. Thermoelectric kuzirala ma modules, TEC modules, peltier modules, thermoelectric modules amagwiritsidwa ntchito kwambiri m'madera azachipatala, asilikali ndi labotale kumene kuwongolera kutentha kwapamwamba ndi kudalirika kumafunika.

Momwe mungasankhire mtundu woyenera ndi chiyambi cha kugwiritsa ntchito ma module a thermoelectric, ma module ozizira a thermoelectric, ma module a TE. Pokhapokha posankha gawo lozizira la thermoelectric komwe cholinga chowongolera kutentha chikhoza kukwaniritsidwa. Musanasankhe gawo la Peltier, gawo la TEC, gawo la thermoelectric, m'pofunika choyamba kufotokozera zofunikira zoziziritsa, zomwe cholinga cha kuzizira ndi chiyani, ndi mtundu wanji wa teknoloji yozizira yomwe mungasankhe, ndi mtundu wanji wa njira yoyendetsera kutentha, kutentha kwa chandamale ndi chiyani, ndi mphamvu zingati zomwe zingaperekedwe. Ngati mukufuna kusankha ma module ozizira a thermoelectric, gawo la thermoelectric, ma module a peltier, gawo la TEC, zinthu za peltier kuchokera ku Beijing Huimao Cooling Equipment Co., Ltd., mutha kudziwa mtundu wofunikira kudzera munjira zotsatirazi.

1. Yerekezerani kuchuluka kwa kutentha

Kutentha kwa kutentha kumatanthawuza kuchuluka kwa kutentha komwe kumafunika kuchotsedwa kuti muchepetse kutentha kwa chandamale chozirira mpaka pamlingo wodziwika pansi pa kutentha kwina, pomwe chipangizocho chimakhala W (watt). Kutentha kwakukulu kumaphatikizapo zolemetsa zogwira ntchito, zolemetsa, ndi kuphatikiza kwake. Kutentha kwachangu ndi kutentha komwe kumapangidwa ndi cholinga chozizira chokha. Kutentha kwapang'onopang'ono ndi kuchuluka kwa kutentha komwe kumayambitsidwa ndi ma radiation akunja, convection ndi conduction. Fomula yowerengera yogwira

Qactive = V2/R = VI = I2R;

Qactive = Kutentha kwachangu (W);

V = Mphamvu yamagetsi yomwe ikugwiritsidwa ntchito ku cholinga cha firiji (V);

R = Kukana chandamale cha firiji;

I = Panopa ikuyenda mu chandamale chokhazikika (A)

Kutentha kwamphamvu ndi kuchuluka kwa kutentha komwe kumasamutsidwa kupita ku chinthu chomwe mukufuna kudzera mu radiation ya electromagnetic. Fomula yowerengera:

Qrad = F es A (Tamb4 – Tc4);

Qrad = Katundu wotentha kwambiri (W);

F = mawonekedwe a mawonekedwe (mtengo woipitsitsa = 1);

e = kutulutsa mpweya (mtengo woipa kwambiri = 1);

s = Stefan-Boltzmann nthawi zonse (5.667 X 10-8W/m² k4);

A = Malo ozizira (m²);

Tamb = Kutentha Kozungulira (K);

Tc = TEC – Kuzizira kozizira kutentha (K).

Convective kutentha katundu ndi kutentha katundu anasamutsidwa mwachibadwa ndi madzimadzi kudutsa pamwamba pa chandamale chinthu kuchokera kunja. Fomula yowerengera ndi:

Qconv = hA (Tair – Tc);

Qconv = Katundu wotentha wa Convective (W)

h = Convective heat transfer coefficient (W/m ² °C) (mtengo wamba wa ndege yamadzi pamlengalenga wokhazikika) = 21.7 W/m² °C;

A = Malo apamwamba (m²);

Tair = Kutentha kozungulira (°C);

Tc = Kutentha kozizira (°C);

Conductive kutentha katundu ndi kutentha katundu anasamutsidwa kuchokera kunja kudzera kukhudzana zinthu pamwamba pa chandamale chinthu. Fomula yowerengera ndi:

Qcond =k A DT/L;

Qcond = Kutumiza kutentha (W);

k = Thermal conductivity of thermal conductive material (W/m °C);

A = Malo opangira matenthedwe opangira matenthedwe (m²);

L = Kutalika kwa njira yoyendetsera kutentha (m)

DT = Kusiyana kwa kutentha kwa njira yopititsira kutentha (°C) (kawirikawiri kutanthauza kutentha kozungulira kapena kutentha kwa sinki ya kutentha kuchotsera kuzizira komaliza.)

Pakuphatikiza kutentha kwa convection ndi conduction, chilinganizo chowerengera ndi:

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

Qpassive = Katundu wa kutentha (W);

A = Chigawo chonse cha chipolopolo (m2);

x = makulidwe a insulation layer (m)

k = Insulation thermal conductivity (W/m °C);

h = kutengera kutentha kwapakati (W/m² °C)

DT = Kusiyana kwa kutentha (°C).

2. Werengani kuchuluka kwa kutentha

Kupyolera mu sitepe yoyamba, tikhoza kuwerengera kuchuluka kwa kutentha kwa cholinga cha firiji.

Tiyerekeze mu pulojekiti yeniyeni, kutentha kwachangu ndi 8W, kutentha kwa kutentha ndi 0.2W, kutentha kwa convective ndi 0.8W, kutentha kwa conductive ndi 0W, ndi kutentha kwathunthu ndi 9W.

3. Kutanthauzira kutentha

Tangoganizani kutentha kwakumapeto kotentha, kutentha kwakumapeto kozizira ndi kusiyana kwa kutentha kwa firiji. Tiyerekeze mu polojekiti yeniyeni, kutentha kozungulira ndi 27°C, kuzizira kwa cholinga chozizira ndi -8°C, ndi kusiyana kwa kutentha kwa DT=35°C.

Pongoganiza kuti kutentha kwathunthu kwa chandamale choziziritsa akuyerekezeredwa kukhala 9W kutengera zomwe zayerekeza kale, Qmax yokwanira imatha kupezeka ngati 9/0.25=36W, ndi Qmax yochuluka ngati 9/0.45=20. Sakani m'gulu lazinthu za Beijing Huimao Cooling Equipment Co., Ltd kuti mupeze ma module ozizirira a thermoelectric, ma module a peltier, zida za peltier, ma module a peltier.TEC ndikupeza zinthuzo ndi Qmax kuyambira 20 mpaka 36.
