Ukadaulo wa Thermoelectric Cooling (TEC) wapita patsogolo kwambiri pa zipangizo, kapangidwe kake, kugwiritsa ntchito bwino mphamvu komanso momwe zimagwiritsidwira ntchito.

Kuyambira mu 2025, ukadaulo wa Thermoelectric Cooling (TEC) wapita patsogolo kwambiri pa zipangizo, kapangidwe kake, kugwiritsa ntchito bwino mphamvu komanso njira zogwiritsira ntchito. Izi ndi zomwe zikuchitika posachedwapa pakukula kwa ukadaulo komanso kupita patsogolo kwamakono.

I. Kupititsa patsogolo mfundo zazikulu mosalekeza

Zotsatira za Peltier zimakhalabe zofunika kwambiri: poyendetsa ma semiconductor awiriawiri a mtundu wa N/P (monga zinthu zopangidwa ndi Bi₂Te₃) ndi mphamvu yamagetsi yolunjika, kutentha kumatulutsidwa kumapeto otentha ndikuyamwa kumapeto ozizira.

Mphamvu yowongolera kutentha mbali zonse ziwiri: Imatha kuziziritsa/kutentha pongosintha njira yamagetsi, ndipo imagwiritsidwa ntchito kwambiri pazochitika zowongolera kutentha kwambiri.

II. Kupambana kwa zinthu zakuthupi

1. Zipangizo zatsopano zamagetsi

Bismuth telluride (Bi₂Te₃) ikadali yodziwika bwino, koma kudzera mu nanostructure engineering ndi doping optimization (monga Se, Sb, Sn, ndi zina zotero), mtengo wa ZT (optimal value coefficient) wakula kwambiri. ZT ya zitsanzo zina za labotale ndi yayikulu kuposa 2.0 (mwachikhalidwe pafupifupi 1.0-1.2).

Kupanga mwachangu zinthu zina zopanda lead/zopanda poizoni wambiri

Zipangizo zopangidwa ndi Mg₃(Sb,Bi)₂

SnSe single crystal

Half-Heusler alloy (yoyenera magawo otentha kwambiri)

Zipangizo zophatikizika/zowala: Kapangidwe ka mitundu yosiyanasiyana kangathe kukonza mphamvu zamagetsi ndi mphamvu zamagetsi nthawi imodzi, kuchepetsa kutaya kwa kutentha kwa Joule.

III, Zatsopano mu dongosolo la kapangidwe ka zinthu

1. Kapangidwe ka thermopile ya 3D

Gwiritsani ntchito njira zoyimirira kapena zomangira zazing'ono kuti muwonjezere mphamvu yozizira pa gawo lililonse.

Module ya TEC ya cascade, module ya peltier, chipangizo cha peltier, module ya thermoelectric imatha kutentha kwambiri mpaka -130℃ ndipo ndi yoyenera kafukufuku wasayansi komanso kuzizira kwamankhwala.

2. Kulamulira modular komanso mwanzeru

Sensa yolumikizira kutentha + njira ya PID + PWM drive, zomwe zimapangitsa kuti kutentha kukhale kolondola kwambiri mkati mwa ±0.01℃.

Imathandizira kuwongolera kutali kudzera pa intaneti ya Zinthu, yoyenera unyolo wanzeru wozizira, zida za labotale, ndi zina zotero.

3. Kukonza bwino kayendetsedwe ka kutentha mogwirizana

Kutentha kowonjezereka kwa mbali yozizira (microchannel, PCM)

Mapeto otentha amagwiritsa ntchito ma graphene heat sinks, Vapor chambers kapena micro-fan arrays kuti athetse vuto la "kusonkhanitsa kutentha".

IV, zochitika ndi minda yogwiritsira ntchito

Chisamaliro chamankhwala ndi thanzi: zida za thermoelectric PCR, zipangizo zokongoletsa za laser zoziziritsira kutentha, mabokosi onyamulira osungira katemera m'firiji

Kulankhulana kwa kuwala: Kulamulira kutentha kwa gawo la kuwala la 5G/6G (kukhazikika kwa kutalika kwa laser)

Zipangizo zamagetsi za ogula: Zitseko zoziziritsira kumbuyo za mafoni, kuziziritsa kwa ma headset a AR/VR a thermoelectric, mafiriji ang'onoang'ono oziziritsira a peltier, choziziritsira vinyo choziziritsira cha thermoelectric, mafiriji a magalimoto

Mphamvu yatsopano: Kabati yotenthetsera nthawi zonse ya mabatire a drone, kuziziritsa kwapafupi kwa makabati amagetsi a magalimoto

Ukadaulo wa zakuthambo: kuziziritsa kwa thermoelectric kwa zozindikira za infrared za satellite, kuwongolera kutentha mu malo opanda mphamvu yokoka a malo osungiramo zinthu zakuthambo

Kupanga ma semiconductor: Kuwongolera kutentha kolondola kwa makina ojambulira zithunzi, nsanja zoyesera ma wafer

V. Mavuto a Ukadaulo Amakono

Kugwiritsa ntchito mphamvu moyenera kumakhala kotsika poyerekeza ndi momwe compressor imasungidwira (nthawi zambiri COP imakhala yochepera 1.0, pomwe compressor imatha kufika 2-4).

Mtengo wokwera: Zipangizo zogwira ntchito bwino komanso ma phukusi olondola zimakweza mitengo

Kutaya kutentha kumapeto kwa kutentha kumadalira dongosolo lakunja, lomwe limaletsa kapangidwe kakang'ono.

Kudalirika kwa nthawi yayitali: Kusinthasintha kwa kutentha kumayambitsa kutopa kwa mafupa osweka komanso kuwonongeka kwa zinthu

VI. Malangizo a Chitukuko cha M'tsogolo (2025-2030)

Zipangizo zamagetsi zotentha kutentha kwa chipinda zokhala ndi ZT > 3 (Kupambana kwa malire a chiphunzitso)

Zipangizo za TEC zosinthika/zovalidwa, ma module a thermoelectric, ma module a peltier (a khungu lamagetsi, kuyang'anira thanzi)

Dongosolo lowongolera kutentha losinthika pamodzi ndi AI

Ukadaulo wopanga zinthu zobiriwira komanso wobwezeretsanso zinthu (Kuchepetsa Mapazi a Zachilengedwe)

Mu 2025, ukadaulo woziziritsa wa thermoelectric ukusintha kuchoka pa "kuwongolera kutentha kolondola" kupita ku "kugwiritsa ntchito bwino komanso kwakukulu". Ndi kuphatikiza kwa sayansi ya zinthu, kukonza kwa micro-nano ndi kuwongolera mwanzeru, kufunika kwake kwanzeru m'magawo monga kuzizira kopanda mpweya, kuyeretsa kutentha kwamagetsi kodalirika kwambiri komanso kuwongolera kutentha m'malo apadera kukuchulukirachulukira.
