Beijing Huimao Cooling Equipment Co., Ltd. yayambitsa mndandanda wa ma module oziziritsa a thermoelectric, ma module a thermoelectric, ma element a peltier, zida za peltier, kuphatikiza ma module oziziritsa a thermoelectric standard batch, ma module a TEC ndi ma module apadera a thermoelectric, ma module a peltier, ma element a peltier malinga ndi zosowa za makasitomala. Pali ma module a thermoelectric a gawo limodzi, zida za peltier, ma module a TEC komanso ma module oziziritsa a thermoelectric a magawo ambiri, ma module a thermoelectric, ma cooler a peltier monga ma stage awiri, atatu mpaka asanu ndi limodzi. Ma module oziziritsa a thermoelectric (ma module a thermoelectric, ma element a peltier) amagwiritsa ntchito mphamvu ya thermoelectric ya ma semiconductor. Mphamvu yolunjika ikadutsa mu thermocouple yopangidwa polumikiza zida ziwiri zosiyana za semiconductor motsatizana, ma end ozizira ndi ma end otentha motsatana amatenga ndikutulutsa kutentha, zomwe zimapangitsa kuti zikhale chisankho chabwino kwambiri pakugwiritsa ntchito kutentha. Sichifuna refrigerant iliyonse, imatha kugwira ntchito mosalekeza, ilibe gwero la kuipitsidwa komanso ilibe magawo ozungulira, ndipo sipanga zotsatira zozungulira. Kuphatikiza apo, ilibe magawo otsetsereka, imagwira ntchito popanda kugwedezeka kapena phokoso, imakhala ndi moyo wautali wautumiki ndipo ndi yosavuta kuyiyika. Ma module oziziritsira a Thermoelectric, ma module a TEC, ma module a peltier, ma module a thermoelectric amagwiritsidwa ntchito kwambiri m'magawo azachipatala, ankhondo ndi a labotale komwe kumafunika kulondola komanso kudalirika kowongolera kutentha kwambiri.
Momwe mungasankhire mtundu woyenera ndiye chiyambi cha kugwiritsa ntchito ma module a thermoelectric, ma module oziziritsa a thermoelectric, ma module a TE. Pokhapokha posankha module yoziziritsa ya thermoelectric ndi pomwe cholinga chowongolera kutentha chomwe chikuyembekezeka chingapezeke. Musanasankhe module ya Peltier, module ya TEC, module ya thermoelectric, ndikofunikira choyamba kufotokozera zofunikira pakuziziritsa, cholinga cha kuziziritsa ndi chiyani, mtundu wa ukadaulo wozizira womwe mungasankhe, mtundu wa njira yoyendetsera kutentha, kutentha komwe mukufuna, komanso kuchuluka kwa mphamvu zomwe zingaperekedwe. Ngati mukufuna kusankha ma module oziziritsa a thermoelectric, module ya thermoelectric, ma module a peltier, module ya TEC, zinthu za peltier kuchokera ku Beijing Huimao Cooling Equipment Co., Ltd., mutha kudziwa mtundu wofunikira kudzera mu njira zotsatirazi zosankhira.
1. Yerekezerani kuchuluka kwa kutentha
Kulemera kwa kutentha kumatanthauza kuchuluka kwa kutentha komwe kumafunika kuchotsedwa kuti kuchepetse kutentha kwa choziziritsira kufika pamlingo winawake pansi pa kutentha kwina, ndipo unit ndi W (watt). Kulemera kwa kutentha kumaphatikizapo katundu wogwira ntchito, katundu wosagwira ntchito, ndi kuphatikiza kwawo. Kulemera kwa kutentha kogwira ntchito ndi katundu wotentha wopangidwa ndi choziziritsira chokha. Kulemera kwa kutentha kosagwira ntchito ndi katundu wotentha woyambitsidwa ndi kuwala kwakunja, convection ndi conduction. Fomula yowerengera katundu wogwira ntchito
Qactive = V2/R = VI = I2R;
Qactive = Kulemera kwa kutentha kogwira ntchito (W);
V = Voltage yomwe imagwiritsidwa ntchito pa cholinga choziziritsira (V);
R = Kukana kwa cholinga cha firiji;
I = Mphamvu yamagetsi ikuyenda kudzera mu chowunikira chozizira (A)
Kulemera kwa kutentha ndi katundu wotentha womwe umasamutsidwira ku chinthu chomwe chikufunidwa kudzera mu kuwala kwamagetsi. Fomula yowerengera:
Qrad = F es A (Tamb4 – Tc4);
Qrad = Kulemera kwa kutentha (W);
F = chinthu choyimira mawonekedwe (mtengo woyipa kwambiri = 1);
e = kutulutsa (mtengo woyipa kwambiri = 1);
s = Stefan-Boltzmann wosasintha (5.667 X 10-8W/m² k4);
A = Malo ozizira (m²);
Tamb = Kutentha kwa Ambient (K);
Tc = TEC – Kutentha kozizira (K).
Kulemera kwa kutentha kozungulira ndi kulemera kwa kutentha komwe kumasamutsidwa mwachibadwa ndi madzi omwe amadutsa pamwamba pa chinthu chomwe chikufunidwa kuchokera kunja. Fomula yowerengera ndi iyi:
Qconv = hA (Tair – Tc);
Qconv = Kulemera kwa kutentha kozungulira (W)
h = Kuchuluka kwa kutentha kosinthika (W/m² °C) (mtengo wamba wa ndege yamadzi pamlengalenga umodzi wokhazikika) = 21.7 W/m² °C;
A = Malo Ozungulira (m²);
Tair = Kutentha kozungulira (°C);
Tc = Kutentha kozizira (°C);
Katundu wotenthetsera ndi katundu wotenthetsera womwe umasamutsidwa kuchokera kunja kudzera mu zinthu zolumikizana pamwamba pa chinthu chomwe chikufunidwa. Fomula yowerengera ndi iyi:
Qcond =k A DT/L;
Qcond = Kutumiza kutentha (W);
k = Kuyendetsa kwa kutentha kwa zinthu zoyendetsera kutentha (W/m °C);
A = Malo ozungulira a zinthu zoyendetsera kutentha (m²);
L = Kutalika kwa njira yopititsira kutentha (m)
DT = Kusiyana kwa kutentha kwa njira yoperekera kutentha (°C) (nthawi zambiri kumatanthauza kutentha kwa malo ozungulira kapena kutentha kwa sinki yotenthetsera kupatula kutentha kwa kumapeto kozizira.)
Pa kutentha komwe kumaphatikizidwa kwa convection ndi conduction, njira yowerengera ndi iyi:
Q passive = (A x DT)/(x/k + 1/h);
Qpassive = Kulemera kwa kutentha (W);
A = Malo onse pamwamba pa chipolopolo (m2);
x = Kukhuthala kwa gawo lotetezera kutentha (m)
k = Kutenthetsa kwa kutentha kwa insulation (W/m °C);
h = Kuchuluka kwa kutentha kosinthika (W/m² °C)
DT = Kusiyana kwa kutentha (°C).
2. Werengani kutentha konse
Mu gawo loyamba, titha kuwerengera kuchuluka kwa kutentha komwe kumafunika pa malo oziziritsira.
Tiyerekeze kuti mu projekiti yeniyeni, mphamvu yogwira ntchito yotenthetsera ndi 8W, mphamvu yowala yotenthetsera ndi 0.2W, mphamvu yozungulira yotenthetsera ndi 0.8W, mphamvu yoyendetsa yoyendetsa ndi 0W, ndipo mphamvu yonse yotenthetsera ndi 9W.
3. Tanthauzirani kutentha
Fotokozani kutentha kwa kutentha, kutentha kwa kuzizira ndi kusiyana kwa kutentha kwa firiji pa pepala loziziritsira. Tiyerekeze kuti mu polojekiti yeniyeni, kutentha kwa malo ozungulira ndi 27°C, kutentha kwa malo oziziritsira ndi -8°C, ndipo kusiyana kwa kutentha kwa kuzizira DT = 35°C
Poganiza kuti kutentha konse kwa cholinga choziziritsira kukuyerekezeredwa kukhala 9W kutengera kuyerekezera kwapitako, Qmax yabwino kwambiri ingapezeke ngati 9/0.25=36W, ndipo Qmax yayikulu ingapezeke ngati 9/0.45=20. Fufuzani kabukhu kazinthu ka Beijing Huimao Cooling Equipment Co., Ltd kuti mupeze ma module oziziritsira a thermoelectric, ma module a peltier, zida za peltier, ma module a peltier.TEC ndikupeza zinthu zomwe zili ndi Qmax kuyambira 20 mpaka 36.
