Ungakhetha kanjani amamojula okupholisa e-thermoelectric (amamojula e-thermoelectric)?

I-Beijing Huimao Cooling Equipment Co., Ltd. yethule uchungechunge lwamamojula okupholisa e-thermoelectric, amamojula e-thermoelectric, izakhi ze-peltier, amadivayisi e-peltier, kufaka phakathi amamojula okupholisa e-thermoelectric ajwayelekile, amamojula e-TEC namamojula e-thermoelectric akhethekile enziwe ngokwezifiso, amamojula e-peltier, izakhi ze-peltier ngokwezidingo zamakhasimende. Kukhona amamojula e-thermoelectric esigaba esisodwa, amadivayisi e-peltier, amamojula e-TEC kanye namamojula okupholisa e-thermoelectric esigaba esiningi, amamojula e-thermoelectric, ama-peltier coolers afana nezigaba ezimbili, ezintathu kuya kweziyisithupha. Amamojula okupholisa e-thermoelectric (amamojula e-thermoelectric, izakhi ze-peltier) asebenzisa umphumela we-thermoelectric wama-semiconductor. Lapho ugesi oqondile udlula ku-thermocouple owakhiwe ngokuxhuma izinto ezimbili ezahlukene ze-semiconductor ochungechungeni, ukuphela okubandayo kanye nokuphela okushisayo ngokulandelana kumunca futhi kukhiphe ukushisa, okwenza kube ukukhetha okuhle kokusetshenziswa kokujikeleza kokushisa. Akudingi noma yisiphi isiqandisi, kungasebenza ngokuqhubekayo, akunamthombo wokungcola futhi akunazingxenye ezijikelezayo, futhi ngeke kukhiqize umphumela ojikelezayo. Ngaphezu kwalokho, ayinazo izingxenye ezishelelayo, isebenza ngaphandle kokudlidliza noma umsindo, inokuphila isikhathi eside kwenkonzo futhi kulula ukuyifaka. Amamojula okupholisa e-Thermoelectric, amamojula e-TEC, amamojula e-peltier, amamojula e-thermoelectric asetshenziswa kabanzi emikhakheni yezokwelapha, yezempi neyelebhu lapho kudingeka khona ukunemba nokuthembeka kokulawula izinga lokushisa eliphezulu.

Indlela yokukhetha uhlobo olufanele ukuqala kokusetshenziswa kwamamojula we-thermoelectric, amamojula okupholisa we-thermoelectric, amamojula we-TE. Umgomo wokulawula izinga lokushisa okulindelekile ungafinyelelwa kuphela ngokukhetha imojula yokupholisa ye-thermoelectric. Ngaphambi kokukhetha imojula ye-Peltier, imojula ye-TEC, imojula ye-thermoelectric, kubalulekile ukucacisa kuqala izidingo zokupholisa, ukuthi iyiphi into eqondiwe yokupholisa, uhlobo luni lobuchwepheshe bokupholisa okufanele ukhethe, uhlobo luni lwendlela yokuqhuba ukushisa, ukuthi izinga lokushisa eliqondiwe liyini, nokuthi amandla angakanani anganikezwa. Uma uhlela ukukhetha amamojula okupholisa we-thermoelectric, imojula ye-thermoelectric, amamojula we-peltier, imojula ye-TEC, izakhi ze-peltier ezivela eBeijing Huimao Cooling Equipment Co., Ltd., unganquma imodeli edingekayo ngezinyathelo ezilandelayo zokukhetha.

1. Linganisela umthwalo wokushisa

Umthwalo wokushisa ubhekisela enanini lokushisa okudingeka lisuswe ukuze kwehliswe izinga lokushisa lethagethi yokupholisa liye ezingeni elithile ngaphansi kwendawo ethile yokushisa, lapho iyunithi ingu-W (watt). Imithwalo yokushisa ihlanganisa kakhulu imithwalo esebenzayo, imithwalo engasebenzi, kanye nokuhlanganiswa kwayo. Umthwalo wokushisa osebenzayo umthwalo wokushisa okhiqizwa yithagethi yokupholisa uqobo. Umthwalo wokushisa ongasebenzi umthwalo wokushisa obangelwa imisebe yangaphandle, i-convection kanye nokuqhuba. Ifomula yokubala umthwalo osebenzayo

I-Qactive = V2/R = VI = I2R;

I-Qactive = Umthwalo wokushisa osebenzayo (W);

V = I-voltage esetshenziswa endaweni yokuqandisa (V);

R = Ukumelana kwenhloso yokuqandisa;

I = Umsinga ogeleza endaweni epholile (A)

Umthwalo wokushisa ogqamile umthwalo wokushisa odluliselwa entweni eqondiwe ngemisebe kagesi. Ifomula yokubala:

I-Qrad = F es A (Tamb4 – Tc4);

I-Qrad = Umthwalo wokushisa okhanyayo (W);

F = isici somumo (inani elibi kakhulu = 1);

e = ukukhishwa kwegesi (inani elibi kakhulu = 1);

s = ukuqina kukaStefan-Boltzmann (5.667 X 10-8W/m² k4);

A = Indawo yokupholisa (m²);

I-Tamb = Izinga Lokushisa Eliphakathi (K);

I-Tc = I-TEC – Izinga lokushisa elibandayo (K).

Umthwalo wokushisa oguquguqukayo umthwalo wokushisa odluliselwa ngokwemvelo uketshezi oludlula ebusweni bento eqondiwe luvela ngaphandle. Ifomula yokubala ithi:

I-Qconv = hA (Tair – Tc);

I-Qconv = Umthwalo wokushisa oguquguqukayo (W)

h = I-coefficient yokudlulisa ukushisa okuguquguqukayo (W/m² °C) (inani elijwayelekile lendiza yamanzi endaweni eyodwa evamile) = 21.7 W/m² °C;

A = Indawo engaphezulu (m²);

I-Tair = Izinga lokushisa le-ambient (°C);

I-Tc = Izinga lokushisa lokuphela okubandayo (°C);

Umthwalo wokushisa oqhubayo umthwalo wokushisa odluliselwa usuka ngaphandle ngokusebenzisa izinto zokuxhumana ebusweni bento eqondiwe. Ifomula yokubala ithi:

I-Qcond =k A DT/L;

I-Qcond = Umthwalo wokushisa odluliselwe (W);

k = Ukuqhuba kwe-thermal kwezinto eziqhuba i-thermal (W/m °C);

A = Indawo enqamula ingxenye yezinto eziqhuba ukushisa (m²);

L = Ubude bendlela yokuqhuba ukushisa (m)

I-DT = Umehluko wokushisa kwendlela yokuqhuba ukushisa (°C) (ngokuvamile ubhekisela ekushiseni okuzungezile noma ekushiseni kokushisa ngaphandle kokushisa kokuphela kokubanda.)

Ngomthwalo wokushisa ohlangene we-convection kanye ne-conduction, ifomula yokubala yile:

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

Qpassive = Umthwalo wokushisa (W);

A = Indawo yonke yobuso begobolondo (m2);

x = Ubukhulu besendlalelo sokufaka umswakama (m)

k = Ukushisa kokushisa kokushisa (W/m °C);

h = I-coefficient yokudlulisa ukushisa okuguquguqukayo (W/m² °C)

I-DT = Umehluko wokushisa (°C).

2. Bala umthwalo wokushisa ophelele

Ngesinyathelo sokuqala, singabala inani eliphelele lomthwalo wokushisa wethagethi yokuqandisa.

Ake sithi kuphrojekthi yangempela, umthwalo wokushisa osebenzayo ungu-8W, umthwalo wokushisa okhanyayo ungu-0.2W, umthwalo wokushisa ojikelezayo ungu-0.8W, umthwalo wokushisa oqhubayo ungu-0W, kanti umthwalo wokushisa ophelele ungu-9W.

3. Chaza izinga lokushisa

Chaza izinga lokushisa lokushisa elishisayo, izinga lokushisa lokushisa elibandayo kanye nomehluko wokushisa lokushisa kweshidi lokuqandisa. Ake sithi kuphrojekthi yangempela, izinga lokushisa elizungezile lingu-27°C, izinga lokushisa eliqondiwe lokupholisa lingu-8°C, kanye nomehluko wokushisa lokushisa okupholisa u-DT=35°C.

Uma sicabanga ukuthi inani eliphelele lomthwalo wokushisa wethagethi yokupholisa lilinganiselwa ku-9W ngokusekelwe ekulinganisweni kwangaphambilini, i-Qmax engcono kakhulu ingatholakala njengo-9/0.25=36W, kanye ne-Qmax ephezulu njengo-9/0.45=20. Sesha ikhathalogi yomkhiqizo yeBeijing Huimao Cooling Equipment Co., Ltd ukuthola amamojula okupholisa e-thermoelectric, amamojula e-peltier, amadivayisi e-peltier, amamojula e-peltier.TEC bese uthola imikhiqizo ene-Qmax esukela ku-20 kuya ku-36.
