Ungasarudza sei mamodule ekutonhodza ethermoelectric (mamodule ethermoelectric)?

Beijing Huimao Cooling Equipment Co., Ltd. yatanga nhevedzano yemamodule ekutonhodza ethermoelectric, mamodule ethermoelectric, maelement epeltier, zvishandiso zvepeltier, zvinosanganisira mamodule ethermoelectric cooling ebatch standard, mamodule eTEC uye mamodule ethermoelectric akagadzirwa, mamodule epeltier, maelement epeltier zvichienderana nezvinodiwa nevatengi. Kune mamodule ethermoelectric echikamu chimwe chete, zvishandiso zvepeltier, mamodule eTEC pamwe nemamodule ekutonhodza ethermoelectric echikamu chemulti-stage, mamodule ethermoelectric, macooler epeltier akadai semamodule maviri, matatu kusvika matanhatu. Mamodule ekutonhodza ethermoelectric (mamodule ethermoelectric, maelement epeltier) anoshandisa thermoelectric effect yemasemiconductor. Kana direct current inopfuura nepa thermocouple yakagadzirwa nekubatanidza zvinhu zviviri zvakasiyana zve semiconductor mumutsara, magumo echando nemagumo ekupisa zvinotora nekuburitsa kupisa, zvichiita kuti zvive sarudzo yakanaka yekushandisa tembiricha. Hazvidi refrigerant, zvinogona kushanda nguva dzose, hazvina kusvibiswa uye hazvina zvikamu zvinotenderera, uye hazvizoburitse mhedzisiro inotenderera. Pamusoro pezvo, haina zvikamu zvinotsvedza, inoshanda isina vibration kana ruzha, ine hupenyu hurefu hwebasa uye iri nyore kuisa. Mamodule ekutonhodza eThermoelectric, mamodule eTEC, mamodule epeltier, mamodule ethermoelectric anoshandiswa zvakanyanya muminda yekurapa, yemauto neyemarabhoritari uko kunodiwa kunyatsoongorora tembiricha uye kuvimbika.

Maitiro ekusarudza mhando chaiyo ndiwo kutanga kwekushandiswa kwemamodule ethermoelectric, mamodule ekutonhodza ethermoelectric, mamodule eTE. Chinangwa chekutonga tembiricha chinotarisirwa chete ndicho chinogona kuwanikwa nekusarudza module yekutonhodza yethermoelectric. Usati wasarudza module yePeltier, module yeTEC, module yethermoelectric, zvakakosha kutanga wajekesa zvinodiwa zvekutonhodza, kuti chinangwa chekutonhodza chii, rudzii rwetekinoroji yekutonhodza yekusarudza, rudzii rwenzira yekufambisa kupisa, kuti tembiricha yakatarwa chii, uye kuti simba rakawanda sei rinogona kupihwa. Kana ukaronga kusarudza mamodule ekutonhodza ethermoelectric, module yethermoelectric, mamodule epeltier, module yeTEC, zvinhu zvepeltier kubva kuBeijing Huimao Cooling Equipment Co., Ltd., unogona kusarudza modhi inodiwa kuburikidza nematanho ekusarudza anotevera.

1. Fungidzira mutoro wekupisa

Mutoro wekupisa zvinoreva huwandu hwekupisa hunofanirwa kubviswa kuti tembiricha yechinangwa chekutonhodza ideredzwe kusvika padanho rakatarwa pasi pemamiriro ekunze ekupisa, unit iri W (watt). Mutoro wekupisa unonyanya kusanganisira mitoro inoshanda, mitoro isingashande, uye kusanganiswa kwayo. Mutoro wekupisa unoshanda ndiwo mutoro wekupisa unogadzirwa nechinhu chinotonhodza pachacho. Mutoro wekupisa usingashande ndiwo mutoro wekupisa unokonzerwa nemwaranzi yekunze, convection uye conduction. Fomura yekuverenga mutoro unoshanda

Qactive = V2/R = VI = I2R;

Qactive = Mutoro wekupisa unoshanda (W);

V = Voltage inoshandiswa pachinangwa chekutonhodza (V);

R = Kuramba kwechinangwa chekutonhodza;

I = Mvura inoyerera ichipinda nepachinangwa chakatonhorera (A)

Radiant heat load ndiwo mutoro wekupisa unotamisirwa kuchinhu chaunoda kuburikidza nemwaranzi yemagetsi. Fomura yekuverenga:

Qrad = F es A (Tamb4 – Tc4);

Qrad = Kupisa kunopenya Mutoro (W);

F = chimiro (kukosha kwakanyanya = 1);

e = emissivity (yakaipisisa kukosha = 1);

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

A = Nzvimbo inotonhorera (m²);

Tamb = Tembiricha yemhepo (K);

Tc = TEC – Tembiricha yekunze inotonhora (K).

Convective heat load imhando yekupisa inotamiswa nenzira yechisikigo nemvura inopfuura nepamusoro pechinhu chakanangana nacho kubva kunze. Fomura yekuverenga ndeiyi:

Qconv = hA (Tair – Tc);

Qconv = Mutoro wekupisa unochinjika (W)

h = Kuwanda kwekuchinja kwekupisa kweConvective (W/m² °C) (kukosha kwakajairika kwenzvimbo yemvura pane imwe nzvimbo yakajairika) = 21.7 W/m² °C;

A = Nzvimbo yepamusoro (m²);

Tair = Tembiricha yeAmbient (°C);

Tc = Tembiricha yekupera kwechando (°C);

Mutoro wekupisa unofambiswa nemhepo (conductive heat load) mutoro wekupisa unotamiswa kubva kunze kuburikidza nezvinhu zvinosangana pamusoro pechinhu chakanangana nacho. Fomura yekuverenga ndeiyi:

Qcond =k A DT/L;

Qcond = Mutoro wekupisa wakachinjirwa (W);

k = Kufambisa kwekupisa kwezvinhu zvinofambisa kupisa (W/m °C);

A = Nzvimbo yepakati pechinhu chinofambisa kupisa (m²);

L = Kureba kwenzira yekupisa (m)

DT = Musiyano wekupisa kwenzira yekupisa (°C) (kazhinji zvinoreva tembiricha yemhepo kana tembiricha yekupisa kunze kwetembiricha yekuguma kwechando.)

Pamusanganiswa wemafuta anodziya e convection ne conduction, fomura yekuverenga ndeiyi:

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

Qpassive = Mutoro wekupisa (W);

A = Nzvimbo yose yeganda (m2);

x = Ukobvu hwechikamu chekudzivirira (m)

k = Kufambisa kwekupisa kwekudzivirira (W/m °C);

h = Kuwanda kwekuchinja kwekupisa kweConvective (W/m² °C)

DT = Musiyano wekupisa (°C).

2. Verenga huwandu hwese hwekupisa

Kuburikidza nedanho rekutanga, tinogona kuverenga huwandu hwese hwekupisa hwechinangwa chekufiriji.

Ngatitii muprojekiti chaiyo, mutoro wekupisa unoshanda i8W, mutoro wekupisa unopenya i0.2W, mutoro wekupisa unochinjika i0.8W, mutoro wekupisa unofambisa mhepo i0W, uye mutoro wekupisa wese i9W.

3. Tsanangura tembiricha

Tsanangura musiyano wekupisa kwekunze, kupisa kwekunze kunotonhora uye kupisa kwefiriji kwepepa refiriji. Ngatitii mupurojekiti chaiyo, tembiricha yemhepo iri 27°C, tembiricha yekutonhodza iri -8°C, uye musiyano wekupisa kwekunze DT=35°C

Tichifunga kuti huwandu hwese hwekupisa hwechinangwa chekutonhodza hunofungidzirwa kuva 9W zvichibva pane zvakambofungidzirwa, Qmax yakakwana inogona kuwanikwa se 9/0.25=36W, uye Qmax yepamusoro se 9/0.45=20. Tsvaga mukatalogu yezvigadzirwa zveBeijing Huimao Cooling Equipment Co., Ltd kuti uwane mamodule ekutonhodza ethermoelectric, mamodule epeltier, zvishandiso zvepeltier, mamodule epeltier.TEC uye tsvaga zvigadzirwa zvine Qmax kubva pa20 kusvika 36.
