Zipangizo Zoziziritsira za Thermoelectric mu Ntchito Zaukadaulo za Frontier
Zipangizo zoziziritsira za thermoelectric, ma module oziziritsira a thermoelectric—omwe amadziwika kuti thermoelectric coolers (TECs)—ndi njira zoyendetsera kutentha zomwe zimagwira ntchito popanda ziwalo zosuntha, zomwe zimathandiza kuziziritsa kopanda phokoso, koyankha bwino, komanso kowongoleredwa bwino. Ubwino wawo weniweni—kuphatikizapo compact form factor, scalability, kudalirika pansi pa mikhalidwe yovuta kwambiri, ndi malamulo a kutentha kwapafupi—zawayika ngati zinthu zofunika kwambiri m'madera osiyanasiyana, kuphatikizapo zomangamanga za luntha lochita kupanga, kulumikizana kwamphamvu kwa kuwala, sayansi ya cryogenic, kasamalidwe ka kutentha kwa ma microelectronics, machitidwe azachipatala, ndi kufufuza kwa ndege/nyanja.
1. Zida Zamakono Zamakono Za AI ndi Kulumikizana Kwachangu Kwambiri
Kuchuluka kwa mphamvu kwa ma accelerator a AI komanso kukhazikitsidwa kwa ma transceiver a 800G/1.6T kwawonjezera mavuto a kutentha m'makina ogwiritsira ntchito makompyuta ndi kulumikizana kwa m'badwo wotsatira. Ma TEC amathetsa "khoma lotentha" ili popereka malamulo oyendetsera kutentha omwe ali pamalo oyenera komanso olondola kwambiri.
• Kukhazikika kwa ma module a kuwala: Ma diode a laser m'ma module othamanga kwambiri a kuwala amasonyeza kudalira kwambiri kutentha kwa mafunde. Mwa kuphatikiza mwachindunji ndi chip ya kuwala, ma module a thermoelectric, zida za peltier, ma TEC amasunga kutentha kwa junction mkati mwa ±0.5 °C, potero amachepetsa kusuntha kwa mafunde ndikuchepetsa kuchuluka kwa zolakwika za bit (BER) pakutumiza deta.
• Kusamalira kutentha kwa seva ya AI: Mu ma racks okhala ndi kuchuluka kwa AI, zinthu za peltier, ma module a Thermoelectric, ma TEC akupangidwa kwambiri kuti azitha kutentha kwambiri (>100 W/cm²) komanso kugwiritsa ntchito mphamvu zochepa, zomwe zimapangitsa kuti kutentha kwa GPU, TPU, ndi ma interconnect kukhazikike bwino.
2. Zida Zapamwamba Zasayansi ndi Kuzindikira Kwambiri
Zipangizo zatsopano zamagetsi ndi zomangamanga zikuwonjezera malire ogwirira ntchito mpaka kutentha kochepa kwambiri pomwe zikuwonjezera kudalirika kozindikira.
• Kuziziritsa kwa deep-cryogenic: Ofufuza ku Tongji University adapanga choziziritsira cha Thomson kutengera zinthu za YbInCu₄ phase-transition. Pogwira ntchito mu 38 K regime (~−235 °C), idapeza kuziziritsa kokhazikika kwa ΔT kupitirira 5 K—kuyimira kupita patsogolo mu solid-state cryocooling ya ntchito za quantum ndi low-temperature physics.
• Kujambula zithunzi mozama kwambiri: Ma TEC ang'onoang'ono okhala ndi magawo ambiri, ma module ang'onoang'ono okhala ndi magawo ambiri a peltier (ma module a TEC) amathandizira kuti detector izizire kufika pa −60 °C–−80 °C mu infrared focal plane arrays, X-ray spectrometers, ndi astronomical sensors. Kuletsa phokoso la kutentha kumeneku kumathandizira kwambiri signal-to-noise ratio (SNR), zomwe zimathandiza kuti zithunzi zikhale zowoneka bwino kwambiri pansi pa kuwala kochepa kwambiri kapena vacuum conditions.
3. Kusamalira Kutentha kwa Microscale kwa Zida Zamagetsi Zapamwamba
Pamene ma semiconductor nodes akupitirira pansi pa 3 nm, malo opezeka m'malo osiyanasiyana amawopseza magwiridwe antchito, kudalirika, ndi kukolola. Ma micro-thermoelectric coolers (micro-TECs), ma micro thermoelectric modules, ndi zinthu za mico peltier zimapereka mphamvu yolamulira kutentha kwa pa die kapena pafupi kufa ndi nthawi yoyankha ya sub-milliseconds.
• Kuphatikiza zinthu zatsopano: Gulu lofufuza ku Harbin Institute of Technology (Shenzhen) linapanga chipangizo cha micro-TEC chochokera ku magnesium-bismuth, micro peltier module (chipangizo cha micro peltier) chomwe chikuwonetsa mphamvu yoziziritsira kutentha kwa chipinda (>500 W/cm³) komanso yankho lachangu. Chagwiritsidwa ntchito bwino polamulira kutentha kwa microcontroller unit (MCU) cores.
• Kuziziritsa pa chip ndi pa component level: Ma Micro-TEC, ma micro-peltier elements, ma micro thermoelectric modules, ma Micro TEC modules amaphatikizidwa mwachindunji ku ma CPU apamwamba, ma LiDAR emitters, ndi ma RF front-end modules. Kapangidwe kawo kogwirizana ndi mapazi kumathandiza kuchotsa ma hotspot pa micron scale, kuonetsetsa kuti makompyuta amakhala olimba nthawi zonse pansi pa kutentha kwanthawi zonse.
4. Zipangizo Zamankhwala ndi Kuwunika kwa Unyolo Wozizira
Ma TEC, ma module a TEC (ma module oziziritsira a thermoelectric) amathandizira ntchito zofunika kwambiri za biomedical kudzera mu kukolola mphamvu zopanda mphamvu komanso kulamulira kutentha mwachangu—zonse zofunika pakugwiritsa ntchito zinthu zomwe zimayikidwa m'thupi komanso zomwe zimakhudzidwa ndi zinthu.
• Mphamvu ndi kuziziritsa zomwe zimayikidwa m'thupi: Ofufuza a MIT adawonetsa filimu yopyapyala kwambiri komanso yosinthasintha ya thermoelectric yomwe imayikidwa pansi pa khungu la nkhumba. Pogwiritsa ntchito kutentha kwa ~2.5 K pakati pa minofu yapakati ya thupi ndi khungu, chipangizochi chinagwiritsa ntchito pacemaker ya mtima mosalekeza kwa miyezi isanu ndi inayi—kutsimikizira mphamvu yokhazikika ya bio-integrated kwa nthawi yayitali.
• Kuyang'anira unyolo wozizira wodziyimira pawokha: Ma tag ozindikira kutentha omwe ali ndi ma thermoelectric generators (TEGs) adayikidwa mu katemera wa Pfizer's mRNA. Masensa odziyendetsa okhawa amasonkhanitsa mphamvu ya kutentha kuchokera ku kutentha kwamkati ndi kwakunja kwa katundu kuti ayendetse telemetry yopanda zingwe—kuchotsa kudalira kwa batri ndikulola kuti kutentha kusungidwe kosalekeza komanso kosasinthika nthawi yonse yoyendera.
5. Machitidwe Ovuta a Zachilengedwe: Kufufuza Zamlengalenga ndi Kuzama kwa Nyanja
Ukadaulo wa thermoelectric umapereka mphamvu yolimba, yopanda kukonza kutentha ndi mphamvu m'malo omwe machitidwe achikhalidwe amalephera—makamaka pansi pa vacuum, radiation, kapena kutentha kwambiri.
• Mapulatifomu akuya ndi ozungulira: Mu Mariana Trench Observation Network yotsogozedwa ndi Japan, ma modular thermoelectric generators (TEGs) amasintha >340 K gradient pakati pa hydrothermal vent fluid (~350 °C) ndi madzi am'nyanja (~2 °C) kukhala mphamvu yopitilira ya kilowatt ya machitidwe a kanema wa HD akuya. Nthawi yomweyo, zomangamanga za thermoelectric superlattice zaphatikizidwa mu gawo loyesera la International Space Station kuti libwezeretse kutentha ndi zinyalala komanso kuwongolera kutentha molondola.
• Chitetezo ndi kuzindikira kwa infrared pogwiritsa ntchito mlengalenga: Ma TEC ang'onoang'ono osasinthika, ma module ang'onoang'ono a peltier, ma module ang'onoang'ono a thermoelectric ozizira, ma module ang'onoang'ono a thermoelectric ozizira, amagwiritsidwa ntchito kwambiri mu ma infrared detector oyendetsedwa ndi satellite komanso oyendetsedwa ndi mlengalenga. Kutha kwawo kukwaniritsa kutentha kwa <100 K detector mkati mwa mapazi ang'onoang'ono kwambiri kumathandizira kujambula kwa infrared (LWIR) yokhala ndi mphamvu zambiri, kuti iwonetse bwino komanso kuti iwonetse dziko lapansi.
