Malinga ndi zofunikira posankha ma modules ozizira a thermoelectric, ma modules a TEC, zinthu za peltier

Malinga ndi zofunikira posankha ma module ozizira a thermoelectric, TEC module, zinthu za peltier.

Zofunikira zonse:

①, poganizira kugwiritsa ntchito kutentha kozungulira Th ℃

(2) Kutentha kotsika Tc ℃ komwe kumafikiridwa ndi malo ozizira kapena chinthucho

(3) Kulemera kodziwika kwa kutentha Q (mphamvu ya kutentha Qp, kutayikira kwa kutentha Qt) W

Popeza Th, Tc ndi Q, mulu wofunikira ndi chiwerengero cha milu zitha kuyerekezeredwa malinga ndi mawonekedwe a module ya thermoelectric, chipangizo cha peltier.

Monga gwero lapadera lozizira, gawo loziziritsa la thermoelectric (TE cooler) lili ndi zabwino ndi makhalidwe otsatirawa pakugwiritsa ntchito ukadaulo:

1, Sizifuna refrigerant iliyonse, imatha kugwira ntchito mosalekeza, palibe gwero la kuipitsa mpweya palibe ziwalo zozungulira, sizipanga mphamvu yozungulira, palibe ziwalo zotsetsereka ndi chipangizo cholimba, palibe kugwedezeka, phokoso, moyo wautali, komanso chosavuta kukhazikitsa.

2,

5, Kugwiritsa ntchito molakwika kwa Thermoelectric Module, Pletier Module, chipangizo cha Pletier ndi kupanga mphamvu yosiyana ndi kutentha, Jenereta yamagetsi ya Thermoelectric, jenereta yamagetsi ya thermoelectric, TEG module nthawi zambiri imakhala yoyenera kupanga magetsi m'chigawo chotentha kwambiri.

6, mphamvu ya chinthu chimodzi choziziritsira cha thermoelectric cooling module peltier module TE module ndi yaying'ono kwambiri, koma kuphatikiza kwa zinthu za thermoelectric semiconductor N,P, ndi mtundu womwewo wa zinthu za thermoelectric, njira yofananira ikaphatikizidwa mu dongosolo loziziritsira, mphamvuyo ikhoza kuchitika yayikulu kwambiri, kotero mphamvu yoziziritsira ikhoza kupezeka pakati pa ma milliwatts ochepa mpaka masauzande a ma watts.

7, Kusiyana kwa kutentha kwa ma module a peltier ndi ma module a thermoelectric, kuyambira kutentha kwabwino 90℃ mpaka kutentha kwabwino 130℃ kungapezeke.

Gawo loziziritsira la thermoelectric Peltier module (Thermoelectric module) ndi gawo lamagetsi la DC lolowera, liyenera kukhala ndi magetsi apadera.

1, magetsi a DC. Ubwino wa magetsi a DC ndikuti angagwiritsidwe ntchito mwachindunji popanda kusintha, ndipo vuto lake ndilakuti magetsi ndi mphamvu ziyenera kugwiritsidwa ntchito pa module ya peltier. Peltier element, thermoelectric module, ndipo zina zitha kuthetsedwa ndi mndandanda ndi njira yofananira ya ma module a TEC, ma element a peltier, ma module a thermoelectric.

2. Mphamvu yamagetsi ya Ac. Iyi ndi mphamvu yodziwika bwino, yomwe iyenera kukonzedwa kukhala DC kuti igwiritsidwe ntchito ndi ma modules a thermoelectric cooling modules TEC, ma modules a peltier. Popeza module ya Pletier thermoelectric cooling module ndi chipangizo chamagetsi otsika komanso chamagetsi okwera, kugwiritsa ntchito buck yoyamba, kukonza, kusefa, zina kuti zithandize kugwiritsa ntchito kuyeza kutentha, kuwongolera kutentha, kuwongolera magetsi ndi zina zotero.

3, Popeza gawo la Thermoelectric ndi magetsi a DC, kuchuluka kwa ripple coefficient ya magetsi kuyenera kukhala kochepera 10%, apo ayi kumakhudza kwambiri kuzizira.

4, Voliyumu yogwira ntchito ndi mphamvu ya chipangizo cha peltier ziyenera kukwaniritsa zosowa za chipangizo chogwira ntchito, mwachitsanzo: chipangizo cha 12706, 127 ndi ma thermoelectric module couples, PN ya logarithm ya ma electric couple, voltage yogwira ntchito ya thermoelectric module V= logarithm ya ma electric couple ×0.11, 06 ndi mtengo wapamwamba kwambiri wamagetsi womwe umaloledwa.

5, Mphamvu ya zipangizo zoziziritsira za thermoelectric zozizira ndi kusinthana kwa kutentha ziyenera kubwezeretsedwa kutentha kwa chipinda pamene malekezero awiriwa (nthawi zambiri zimatenga mphindi zoposa 5 kuti zichitike), apo ayi zimakhala zosavuta kuwononga magetsi ndi kusweka kwa mbale zadothi.

6, Chitoliro chamagetsi cha magetsi oziziritsira a thermoelectric ndi chofala.

Gawo lachitatu la kuziziritsa kwa thermoelectric: TES3-20102T125 specifications:
