Zomwe zachitika posachedwa pakukula kwa ma module ozizira a thermoelectric

I. Kafukufuku Wopambana pa Zipangizo ndi Malire a Kugwira Ntchito

1. Kuzama kwa lingaliro la "galasi la phonon - kristalo wamagetsi": •

Zomwe zachitika posachedwapa: Ofufuza afulumizitsa njira yowunikira zinthu zomwe zingatheke zomwe zili ndi kutentha kochepa kwambiri komanso kuchuluka kwa Seebeck kudzera mu kompyuta yothamanga kwambiri komanso kuphunzira kwa makina. Mwachitsanzo, adapeza mankhwala a Zintl phase (monga YbCd2Sb2) okhala ndi mawonekedwe ovuta a kristalo ndi mankhwala ooneka ngati khola, omwe ma ZT awo amaposa a Bi2Te3 achikhalidwe mkati mwa kutentha kwina. •

Njira ya "Entropy engineering": Kuyambitsa kusokonezeka kwa kapangidwe ka zinthu mu ma alloys apamwamba a entropy kapena mayankho olimba azinthu zambiri, omwe amabalalitsa kwambiri ma phononi kuti achepetse kwambiri kutentha popanda kuwononga kwambiri mphamvu zamagetsi, kwakhala njira yatsopano yothandiza yowonjezerera mphamvu ya thermoelectric.

2. Kupita Patsogolo kwa Malire mu Mapangidwe Ochepa ndi A Nano:

Zipangizo zamagetsi zoyezera kutentha zamitundu iwiri: Kafukufuku wa SnSe imodzi/monolayer, MoS₂, ndi zina zotero wasonyeza kuti mphamvu zawo zosungira quantum ndi momwe zinthu zilili pamwamba zimatha kuyambitsa mphamvu zambiri komanso kutentha kochepa kwambiri, zomwe zimapangitsa kuti pakhale njira yopangira ma micro-TEC opyapyala komanso osinthasintha. Ma module oziziritsa a micro thermoelectric, ma micro peltier coolers (Micro peltier elements).

Uinjiniya wa mawonekedwe a nanometer: Kuwongolera bwino ma microstructures monga malire a tirigu, kusokonekera, ndi nano-phase precipitates, monga "zosefera za phonon", kufalitsa mosankha zonyamulira kutentha (ma phonon) pamene kulola ma elekitironi kudutsa bwino, motero kuswa ubale wachikhalidwe wa ma thermoelectric parameters (conductivity, Seebeck coefficient, thermal conductivity).

II. Kufufuza Njira ndi Zipangizo Zatsopano Zosungiramo Zinthu mu Firiji

1. Kuziziritsa kwa thermoelectric pogwiritsa ntchito thermoelectric:

Iyi ndi njira yatsopano yosinthira. Pogwiritsa ntchito kusamuka ndi kusintha kwa gawo (monga electrolysis ndi kulimba) kwa ma ayoni (m'malo mwa ma electron/mabowo) pansi pa mphamvu yamagetsi kuti akwaniritse kuyamwa bwino kwa kutentha. Kafukufuku waposachedwa akuwonetsa kuti ma ionic gels ena kapena ma electrolyte amadzimadzi amatha kupanga kusiyana kwakukulu kwa kutentha kuposa ma TEC achikhalidwe, ma peltier modules, ma TEC modules, ma Thermoelectric coolers, pamagetsi otsika, ndikutsegula njira yatsopano yopangira ukadaulo wozizira wosinthasintha, chete, komanso wogwira mtima kwambiri wa m'badwo wotsatira.

2. Kuyesera kuchepetsa kutentha kwa firiji pogwiritsa ntchito makadi amagetsi ndi makadi opondereza: •

Ngakhale kuti si njira yogwiritsira ntchito mphamvu ya thermoelectric, monga ukadaulo wopikisana pakuziziritsa kwamphamvu, zipangizozi (monga ma polima ndi ziwiya zadothi) zimatha kuwonetsa kusintha kwakukulu kwa kutentha pansi pa mphamvu zamagetsi kapena kupsinjika. Kafukufuku waposachedwa akuyesera kuchepetsa ndikuyika zinthu zamagetsi/zopopera mphamvu, ndikuchita kufananiza kochokera pa mfundo ndi mpikisano ndi TEC, module ya peltier, module yoziziritsa ya thermoelectric, chipangizo cha Peltier kuti afufuze njira zoziziritsira zamagetsi zamagetsi zochepa kwambiri.

III. Malire a Kuphatikiza kwa Machitidwe ndi Kupanga Zinthu Mwatsopano

1. Kuphatikiza pa chip kuti kutentha kutayike "mulingo wa chip":

Kafukufuku waposachedwa akuyang'ana kwambiri pakuphatikiza micro TECgawo laling'ono la thermoelectric， (module yoziziritsira ya thermoelectric), zinthu za peltier, ndi tchipisi zochokera ku silicon modulally (mu chip imodzi). Pogwiritsa ntchito ukadaulo wa MEMS (Micro-Electro-Mechanical Systems), ma micro-scale thermoelectric column arrays amapangidwa mwachindunji kumbuyo kwa chip kuti apereke kuziziritsa kwa "point-to-point" nthawi yeniyeni kwa malo opezeka ma CPU/GPU, omwe akuyembekezeka kuswa bottleneck ya kutentha pansi pa kapangidwe ka Von Neumann. Iyi imaonedwa kuti ndi imodzi mwa njira zothetsera vuto la "khoma lotentha" la tchipisi lamphamvu zamakompyuta mtsogolo.

2. Kusamalira kutentha kogwiritsa ntchito mphamvu zamagetsi zomwe zimavalidwa komanso zosinthasintha:

Kuphatikiza ntchito ziwiri zopangira mphamvu zamagetsi ndi kuziziritsa. Zomwe zachitika posachedwa zikuphatikizapo kupanga ulusi wamagetsi wofewa komanso wamphamvu kwambiri. Izi sizimangopanga magetsi a zida zovalidwa pogwiritsa ntchito kusiyana kwa kutentha.，komanso kukwaniritsa kuziziritsa kwapafupi (monga kuziziritsa yunifolomu yapadera yogwirira ntchito) kudzera mu mphamvu yobwerera m'mbuyo， kukwaniritsa mphamvu zophatikizana komanso kasamalidwe ka kutentha.

3. Kuwongolera kutentha kolondola mu ukadaulo wa quantum ndi biosensing:

Mu magawo amakono monga ma quantum bits ndi masensa okhala ndi mphamvu zambiri, kuwongolera kutentha kolondola kwambiri pamlingo wa mK (millikelvin) ndikofunikira. Kafukufuku waposachedwa akuyang'ana kwambiri pa ma TEC ambiri, ma multi-stage peltier module (thermoelectric cooling module) machitidwe olondola kwambiri (± 0.001°C) ndipo amafufuza kugwiritsa ntchito TEC module, peltier device, peltier cooler, poletsa phokoso, cholinga chake ndikupanga malo otentha okhazikika kwambiri pamapulatifomu a quantum computing ndi zida zozindikira molekyulu imodzi.

IV. Kupanga Zinthu Zatsopano mu Masewero ndi Kukonza Zinthu Mwanzeru

Kapangidwe koyendetsedwa ndi Luntha Lochita Kupanga: Kugwiritsa ntchito AI (monga maukonde olimbana, kuphunzira kolimbikitsa) pakupanga "kapangidwe ka zinthu" motsatizana, kulosera kapangidwe ka zinthu ka multilayer, magawo ndi geometry ya chipangizo kuti akwaniritse kuzizira kwakukulu mkati mwa kutentha kwakukulu, zomwe zimafupikitsa kwambiri nthawi yofufuza ndi chitukuko.

Chidule:

Zomwe zachitika posachedwapa pa kafukufuku wa peltier element, thermoelectric cooling module (TEC module) zikusintha kuchoka pa "kusintha" kupita ku "kusintha". Zinthu zofunika kwambiri ndi izi: •

Mulingo wa zinthu: Kuyambira kugwiritsa ntchito mankhwala osokoneza bongo ambiri mpaka ma atomu-level interfaces ndi entropy engineering control.

Pa mlingo woyambira: Kuyambira kudalira ma elekitironi mpaka kufufuza zonyamulira zatsopano monga ma ayoni ndi ma polaron.

Mulingo wophatikiza: Kuyambira pazigawo zosiyana mpaka kuphatikizika kwakukulu ndi tchipisi, nsalu, ndi zida zamoyo.

Mulingo wa cholinga: Kusamuka kuchoka pa kuziziritsa kwa macro-level kupita ku kuthana ndi mavuto okhudzana ndi kasamalidwe ka kutentha kwa ukadaulo wamakono monga quantum computing ndi optoelectronics yolumikizidwa.

Kupita patsogolo kumeneku kukusonyeza kuti ukadaulo woziziritsa wa thermoelectric wamtsogolo udzakhala wogwira mtima kwambiri, wopangidwa mwanzeru, wanzeru, komanso wolumikizidwa kwambiri pakati pa ukadaulo wazidziwitso, sayansi ya zamoyo, ndi machitidwe amphamvu a m'badwo wotsatira.
