Pehea e koho ai i nā modula hoʻoluʻu thermoelectric (mau modula thermoelectric)?

Ua hoʻokumu ʻo Beijing Huimao Cooling Equipment Co., Ltd. i kahi ʻano o ka thermoelectric cooling modules, thermoelectric modules, peltier elements, peltier device, me ka batch standard thermoelectric cooling modules, TEC modules and customized special thermoelectric modules, peltier modules, peltier element e like me ka makemake o ka mea kūʻai. Loaʻa nā modula thermoelectric hoʻokahi pae, nā mea peltier, nā modula TEC a me nā modula hoʻoluʻu thermoelectric multi-stage, nā modula thermoelectric, nā mea hoʻoluʻu peltier e like me ʻelua-pae, ʻekolu-pae a ʻeono-pae. Hoʻohana nā modula hoʻoluʻu Thermoelectric (thermoelectric modules, peltier elements) i ka hopena thermoelectric o semiconductors. Ke hele ke au pololei i loko o kahi thermocouple i hana ʻia e ka hoʻohui ʻana i ʻelua mau mea semiconductor like ʻole i ka moʻo, ʻo ka hopena anu a me ka wela wela e hoʻopaʻa a hoʻokuʻu i ka wela, e hoʻolilo iā lākou i koho kūpono no nā noi kaʻa uila. ʻAʻole ia e koi i kahi mea hoʻoheheʻe, hiki ke hana mau, ʻaʻohe kumu pollution a ʻaʻohe ʻāpana ʻōwili, ʻaʻole ia e hana i kahi hopena rotary. Eia kekahi, ʻaʻohe ona ʻāpana sliding, hana me ka ʻole o ka vibration a i ʻole ka walaʻau, he lōʻihi ke ola lawelawe a maʻalahi ke hoʻokomo. Hoʻohana nui ʻia nā modules cooling thermoelectric, TEC modules, peltier modules, thermoelectric modules i ka lāʻau lapaʻau, pūʻali koa a me nā kahua hoʻokolohua kahi e koi ʻia ai ka pololei a me ka hilinaʻi kiʻekiʻe.

Pehea e koho ai i ke ʻano kūpono ka hoʻomaka ʻana o ka hoʻohana ʻana i nā modules thermoelectric, thermoelectric cooling modules, TE modules. Ma ke koho wale ʻana i ka module hoʻoluʻu thermoelectric hiki ke hoʻokō ʻia ka pahu hoʻomalu wela i manaʻo ʻia. Ma mua o ke koho ʻana i kahi module Peltier, TEC module, thermoelectric module, pono e wehewehe mua i nā koi hoʻoluʻu, he aha ka pahuhopu o ka hoʻoluʻu ʻana, he aha ke ʻano o ka ʻenehana hoʻoluʻu e koho ai, he aha ke ʻano o ka wela conduction, he aha ke ʻano wela, a me ka nui o ka mana hiki ke hāʻawi ʻia. Inā hoʻolālā ʻoe e koho i nā modula hoʻoluʻu thermoelectric, module thermoelectric, modules peltier, module TEC, element peltier mai Beijing Huimao Cooling Equipment Co., Ltd., hiki iā ʻoe ke hoʻoholo i ke kumu hoʻohālike i makemake ʻia ma o nā ʻanuʻu koho.

1. E koho i ka ukana wela

ʻO ka haawe wela e pili ana i ka nui o ka wela e pono e hoʻoneʻe ʻia no ka hoʻohaʻahaʻa ʻana i ka wela o kahi pahu hoʻomaha i kahi pae i ʻōlelo ʻia ma lalo o kekahi ʻano wela, me ka ʻāpana W (watt). Hoʻokomo nui nā haʻawe wela i nā haʻawe hana, nā haʻawe passive, a me kā lākou hui pū ʻana. ʻO ka haʻawe wela ʻeleu ka haʻawe wela i hana ʻia e ka pahu hoʻomaha ponoʻī. ʻO ka haʻawe wela passive ka haʻawe wela i hoʻokumu ʻia e ka hoʻoheheʻe waho, convection a me ka conduction. ʻO ke ʻano hoʻohālikelike hoʻouka kaumaha

Qactive = V2/R = VI = I2R;

Qactive = Haawe wela ikaika (W);

V = ʻO ka voltage i hoʻohanaʻia i ka pahu hau hau (V);

R = Kū'ē o ka pahu hau hau;

I = ʻO kēia e kahe ana ma ka pahu hoʻomaha (A)

ʻO ka haʻahaʻa wela kaila ka haʻawe wela i hoʻoili ʻia i ka mea i hoʻopaʻa ʻia ma o ka pāhawewe electromagnetic. Ka helu helu:

Qrad = F es A (Tamb4 – Tc4);

Qrad = Hoʻouka wela ʻulaʻula (W);

F = kumu hoʻohālike (waiwai maikaʻi loa = 1);

e = emissivity (waiwai o ka hihia ino loa = 1);

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

A = ʻāpana ʻili hoʻoluʻu (m ²);

Tamb = Kūlana Kūlohelohe (K);

Tc = TEC – Ka wela wela wela (K).

ʻO ka haʻawe wela convective ka haʻawe wela i hoʻoili maoli ʻia e ka wai e hele ana ma ka ʻili o ka mea i ʻimi ʻia mai waho. ʻO ke kumu helu helu:

Qconv = hA (Tair – Tc);

Qconv = Kaumaha wela convective (W)

h = Huina hoʻoili wela convective (W/m ² °C) (waiwai maʻamau o ka mokulele wai ma hoʻokahi lewa maʻamau) = 21.7 W/m ² °C;

A = ʻAhi ʻili (m ²);

Tair = Ka wela ambient (°C);

Tc = Ka wela wela wela (°C);

ʻO ka haʻawe wela conductive ka haʻawe wela i hoʻoili ʻia mai waho ma o nā mea pili ma ka ʻili o ka mea i hoʻopaʻa ʻia. ʻO ke kumu helu helu:

Qcond =k A DT/L;

Qcond = Hoʻoili ʻia ka ukana wela (W);

k = Ka wela wela o ka mea hoʻoheheʻe wela (W/m °C);

A = ʻO ka ʻāpana keʻa o ka mea hoʻokele wela (m ²);

L = Ka lōʻihi o ke ala lawe wela (m)

DT = ʻO ka ʻokoʻa wela o ke ala hoʻoheheʻe wela (°C) (e pili mau ana i ka wela a i ʻole ka wela wela e hoʻemi ʻia ka wela wela wela.)

No ka haawe wela hui o ka convection a me ka conduction, ka helu helu:

Q hāliu = (A x DT)/(x/k + 1/h);

Qpassive = Haawe wela (W);

A = Ka huina ili o ka pūpū (m2);

x = Mānoanoa o ka papa hoʻopulapula (m)

k = Ka hoʻokaʻawale ʻana i ka wela (W/m °C);

h = Huina hoʻoili wela convective (W/m ² °C)

DT = ʻokoʻa wela (°C).

2. E helu i ka haawe wela a pau

Ma o ka ʻanuʻu mua, hiki iā mākou ke helu i ka huina wela o ka pahu hau.

Inā paha i loko o ka papahana maoli, ʻo 8W ka haʻawe wela ʻeleu, ʻo 0.2W ka haʻawe wela wela, ʻo 0.8W ka haʻawe wela convective, 0W ka haʻawe wela conductive, a ʻo 9W ka nui o ka ukana wela.

3. E wehewehe i ka mahana

E wehewehe i ka wela wela wela, ka wela wela a me ka ʻokoʻa o ka wela wela o ka pepa pahu hau. Inā paha i loko o ka papahana maoli, ʻo 27°C ka wela o ka hoʻoluʻu, ʻo -8°C ka wela hoʻoluʻu, a ʻo ka ʻokoʻa o ka mahana hoʻoluʻu DT=35°C.

Ke manaʻo nei ʻo ka nui o ka haʻalulu wela o ka pahu hoʻomaha i manaʻo ʻia he 9W ma muli o ka manaʻo mua, hiki ke loaʻa ka Qmax maikaʻi loa e like me 9/0.25=36W, a ʻo ka Qmax kiʻekiʻe e like me 9/0.45=20. E ʻimi i ka papa inoa huahana o Beijing Huimao Cooling Equipment Co., Ltd no nā modula hoʻoluʻu thermoelectric, nā modula peltier, nā ʻenehana peltier, nā mea peltier. Nā modula TEC a loaʻa nā huahana me Qmax mai 20 a 36.
