Nzira yekusarudza sei thermoelectric cooling modules (thermoelectric modules)?

Beijing Huimao Cooling Equipment Co., Ltd. yakaparura nhevedzano ye thermoelectric kutonhora modules, thermoelectric modules, peltier elements, peltier devices, zvinosanganisira batch standard thermoelectric cooling modules,TEC modules uye customized special thermoelectric modules,peltier modules,peltier elements maererano nezvinodiwa nevatengi. Kune single-stage thermoelectric modules, peltier zvishandiso,TEC modules pamwe ne-multi-stage thermoelectric cooling modules, thermoelectric modules,peltier coolers senge-matanho maviri, matatu-nhanho kusvika matanhatu-nhanho. Thermoelectric cooling modules (thermoelectric modules, peltier elements) shandisa thermoelectric effect yemasemiconductors. Kana yakananga ikozvino ichipfuura nepakati thermocouple inoumbwa nekubatanidza maviri akasiyana semiconductor zvinhu munhevedzano, iyo inotonhora yekupedzisira uye inopisa inopera zvichiteerana inotora uye kuburitsa kupisa, zvichiita kuti ive sarudzo yakanaka yekushisa bhasikoro maapplication. Izvo hazvidi chero firiji, inogona kushanda nguva dzose, haina kusvibiswa kwemhepo uye haina zvikamu zvinotenderera, uye haizobudisi inotenderera. Mukuwedzera, haina mativi anotsvedza, inoshanda pasina kuzunguzika kana ruzha, ine hupenyu hurefu hwebasa uye iri nyore kuisa. Thermoelectric cooling modules,TEC modules,peltier modules,thermoelectric modules anoshandiswa zvakanyanya munzvimbo dzekurapa, dzechiuto uye murabhoritari uko kunodiwa kwepamusoro tembiricha yekudzora kurongeka uye kuvimbika.

Nzira yekusarudza rudzi rwakakodzera ndiko kutanga kwekushandiswa kwe thermoelectric modules, thermoelectric cooling modules, TE modules. Chete nekusarudza iyo thermoelectric kutonhora module ndiyo inotarisirwa kutonga tembiricha tarisiro inogona kuwanikwa. Usati wasarudza Peltier module, TEC module, thermoelectric module, zvinodikanwa kuti utange wajekesa zvinodiwa zvekutonhodza, kuti chinangwa chekutonhora chii, rudzii rwehunyanzvi hwekutonhodza husarudze, rudzii rwekupisa conduction nzira, chii chinotarirwa tembiricha, uye ingani simba rinogona kupihwa. Kana ukaronga kusarudza thermoelectric cooling modules, thermoelectric module, peltier modules, TEC module, peltier elements kubva kuBeijing Huimao Cooling Equipment Co., Ltd., unogona kuona modhi inodiwa kuburikidza nematanho anotevera ekusarudza.

1. Fungidzira mutoro wekupisa

Heat load (heat load) zvinoreva huwandu hwekupisa hunoda kubviswa kudzikisa tembiricha yechinhu chinotonhodza kusvika padanho rakatarwa pasi peimwe tembiricha, unit iri W (watt). Mitoro yekupisa inonyanya kusanganisira mitoro inoshanda, mitoro inongomira, uye misanganiswa yavo. Iyo inoshanda yekupisa inotakura mutoro wekupisa unogadzirwa neinotonhora chinangwa pachayo. Passive heat load ibasa rinopisa rinokonzerwa neradiation yekunze, convection uye conduction. Active load calculation formula

Qactive = V2/R = VI = I2R;

Qactive = Active kupisa mutoro (W);

V = Mhepo inoshandiswa kune chinangwa chefriji (V);

R = Kupokana kwechinangwa chefiriji;

Ini = Yazvino inoyerera kuburikidza neyakatonhorera chinangwa (A)

Radiant heat load ibasa rekupisa rinoendeswa kune chakanangana nemwaranzi yemagetsi. Calculation formula:

Qrad = F es A (Tamb4 – Tc4);

Qrad = Radiant kupisa Mutoro (W);

F = chimiro chechimiro (yakanyanya kukosha = 1);

e = emissivity (yakaipisisa-yakanyanya kukosha = 1);

s = Stefan-Boltzmann nguva dzose (5.667 X 10-8W/m ² k4);

A = Nzvimbo inotonhorera (m ²);

Tamb = Ambient Temperature (K);

Tc = TEC – Cold end tembiricha (K).

Convective heat load ndiko kupisa kwemoto kunotamiswa nemhepo inopfuura nepamusoro pechinhu chakanangwa kubva kunze. Iyo calculation formula ndeye:

Qconv = hA (Tair – Tc);

Qconv = Convective heat Load (W)

h = Convective heat transfer coefficient (W/m ² °C) (yakajairika kukosha kwendege yemvura pane imwe yakajairika mhepo) = 21.7 W/m ² °C;

A = Nzvimbo yepamusoro (m ²);

Tair = Tembiricha yeAmbient (°C);

Tc = Kutonhora kunopera kupisa (°C);

Conductive heat load ibasa rinopisa rinotamiswa kubva kunze kuburikidza nezvinhu zvinosangana pamusoro pechinhu chakananga. Iyo calculation formula ndeye:

Qcond =k A DT/L;

Qcond = Kutamiswa kupisa mutoro (W);

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

A = Iyo yakayambuka-chikamu nharaunda ye thermal conductive zvinhu (m²);

L = Kureba kwenzira yekupisa yekupisa (m)

DT = Musiyano wetembiricha wenzira yekupisa yekupisa (°C) (kazhinji zvichireva tembiricha yakadzikama kana tembiricha yekunyura inobvisa kutonhora kwekupera.)

Kune iyo yakasanganiswa yekupisa mutoro we convection uye conduction, iyo yekuverenga formula ndeye:

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

Qpassive = Kupisa mutoro (W);

A = Yese pamusoro penzvimbo yegoko (m2);

x = Hukobvu hweiyo insulation layer (m)

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

h = Convective heat transfer coefficient (W/m ² °C)

DT = Musiyano wetembiricha (°C).

2. Verenga huwandu hwekupisa

Kuburikidza nedanho rekutanga, tinokwanisa kuverenga huwandu hwekupisa huwandu hwechinangwa chefiriji.

Ngatitii mupurojekiti chaiyo, iyo inoshanda kupisa mutoro ndeye 8W, iyo inopenya kupisa mutoro ndeye 0.2W, iyo convective kupisa mutoro ndeye 0.8W, iyo conductive kupisa mutoro i0W, uye yakazara kupisa mutoro i9W.

3. Tsanangura tembiricha

Tsanangura tembiricha yekupisa yekupedzisira, kutonhora kwekupedzisira tembiricha uye firiji tembiricha musiyano wefiriji sheet. Ngatitii mupurojekiti chaiyo, tembiricha yepakati i27°C, tembiricha yekutonhora iri -8°C, uye musiyano wetembiricha yekutonhora iDT=35°C.

Tichifunga kuti kupisa kwese kwechinangwa chekutonhora kunofungidzirwa kuva 9W zvichienderana nefungidziro yapfuura, iyo yakakwana Qmax inogona kuwanikwa se 9/0.25 = 36W, uye yakakura Qmax se9/0.45=20. Tsvaga iyo chigadzirwa katalogi yeBeijing Huimao Cooling Equipment Co., Ltd ye thermoelectric cooling modules,peltier modules,peltier devices,peltier elements.TEC modules uye tsvaga zvigadzirwa neQmax kubva pamakumi maviri kusvika makumi matatu nematanhatu.
