2. Zvishandiso zveSainzi zvepamberi uye Kuona Zvakadzama
Zvinhu zvitsva zvemagetsi zvinoshandisa thermoelectric uye magadzirirwo ari kuwedzera miganho yekushanda kusvika pakupisa kwakanyanya ukuwo zvichiwedzera kuvimbika kwekuona.
• Kutonhodza kwakadzika-kwe-cryogenic: Vaongorori vepaTongji University vakagadzira Thomson cooler yakavakirwa paYbInCu₄ phase-transition material. Ichishanda mu38 K regime (~−235 °C), yakawana kutonhodza kwakasimba ΔT inopfuura 5 K—zvichimiririra budiriro mu solid-state cryocooling yekushandiswa kwequantum uye low-temperature physics.
• Kufungidzira mifananidzo ine hunyanzvi hwepamusoro: MaTEC madiki ane nhanho dzakawanda, mamodule epeltier madiki ane nhanho dzakawanda (TEC modules) anogonesa detector kutonhora kusvika −60 °C–−80 °C mu infrared focal plane arrays, X-ray spectrometers, uye astronomical sensors. Kudziviswa uku kweruzha rwekupisa kunovandudza zvikuru signal-to-noise ratio (SNR), zvichiita kuti kuratidzwa kwemifananidzo kuve ne resolution yepamusoro pasi pechiedza chakaderera zvakanyanya kana kuti vacuum conditions.
3. Kutarisirwa kweThermal yeMicroscale yeAdvanced Electronics
Sezvo ma semiconductor nodes achifambira mberi pasi pe3 nm, nzvimbo dzinopisa dzinokanganisa kushanda, kuvimbika, uye goho. Micro-thermoelectric coolers (micro-TECs), micro thermoelectric modules, mico peltier elements dzinopa mutemo wekupisa wepa-die kana pedyo ne-die nenguva dzekupindura dze sub-millisecond.
• Kubatanidzwa kwezvinhu zvitsva: Chikwata chekutsvagisa paHarbin Institute of Technology (Shenzhen) chakagadzira micro-TEC ine magnesium-bismuth, micro peltier module (micro peltier device) inoratidza simba rekutonhodza rinopisa zvakanyanya mukamuri (>500 W/cm³) uye mhinduro yekukurumidza yenguva pfupi. Yakashandiswa zvinobudirira kudzora kupisa kwema microcontroller unit (MCU) cores.
• Kutonhodza kwepa-chip uye padanho rezvikamu: Micro-TECs, micro-peltier elements, micro thermoelectric modules, Micro TEC modules dzakabatanidzwa zvakananga kumaCPU anoshanda zvakanyanya, LiDAR emitters, uye RF front-end modules. Dhizaini yavo inoenderana netsoka inobvumira kubviswa kwehotspot pa micron scale, zvichiita kuti kuve nechokwadi chekuti computer inoramba iripo pasi pekupisa kwakasimba.
4. Zvishandiso zveBiomedical uye Kutarisa Cold-Chain
MaTEC, maTEC modules (ma thermoelectric cooling modules) anotsigira mabasa ekurapa akakosha kuburikidza nekuunganidza simba risingashande uye kudzora kupisa kunoshanda—zvose zvakakosha pakushandisa zvinoiswa mumiti uye zvinotarisa mafambiro ezvinhu.
• Simba rinoiswa uye kutonhora: Vaongorori veMIT vakaratidza firimu rethermoelectric rakatetepa zvikuru, rinochinjika rakaiswa pasi peganda mumhando dzenguruve. Vachishandisa tembiricha ye ~2.5 K pakati penyama yemuviri ne epidermis, mudziyo uyu wakashandisa pacemaker yemwoyo nguva dzose kwemwedzi mipfumbamwe—zvichisimbisa kuzvitonga kwesimba kwenguva refu.
• Kutarisa otomatiki kwechando: Ma tags anonzwa tembiricha anosanganisira ma thermoelectric generators (TEGs) akaiswa muPfizer's mRNA vaccine logistics. Aya ma sensors anozvishandira ega anounganidza simba rekupisa kubva mu internal-external temperature differential ye cargo hold kuti aendese wireless telemetry—kubvisa kushandiswa kwemabhatiri uye zvichiita kuti tembiricha irambe ichiongororwa nguva dzose, isingakanganiswe nechinhu panguva yekufamba.
5. Masisitimu Ezvakatipoteredza Akaoma: Kutsvaga Mudenga neGungwa Rakadzika
Tekinoroji yeThermoelectric inopa simba rakasimba, risingagadzirisike uye risingagadzirisike munzvimbo umo masisitimu akajairwa anokundikana—kunyanya pasi pevacuum, panowanikwa mwaranzi, kana kuti panopisa zvakanyanya.
• Mapuratifomu egungwa rakadzika uye emuchadenga: MuMariana Trench Observation Network inotungamirwa neJapan, majenereta emodular thermoelectric (TEGs) anoshandura >340 K gradient pakati pe hydrothermal vent fluid (~350 °C) nemvura yegungwa iri mumhepo (~2 °C) kuita kilowatt-level continuous power ye HD video systems yakadzika mugungwa. Panguva imwe chete, zvivakwa zve thermoelectric superlattice zvakabatanidzwa muInternational Space Station's experimental module yekudzoreredza marara-kupisa uye kudzora kupisa kwakanyatsojeka.
• Kunzwa kwe infrared nekudzivirira kubva muchadenga: Ma TEC e micro-stage asingatsvedzere, ma micro-stage akawanda eTEC, ma micro-stage peltier modules ma micro-stage akawanda e thermoelectric cooling modules, ma micro-thermoelectric coolers, anoshandiswa zvakanyanya mu infrared detectors dzinofambiswa nesatellite uye dziri mumhepo. Kugona kwavo kuwana tembiricha dze <100 K detector mukati me ultra-compact footprints kunotsigira high-sensitivity, long-wave infrared (LWIR) imaging yekutarisa zvine hungwaru uye kuongorora pasi.
