Kugwiritsa ntchito ma module a peltier, ma module a thermoelectric mu owongolera kutentha
Gawo loziziritsira la thermoelectric (peltier element)—lomwe limatchedwa thermoelectric coolers (TECs)—ndi zigawo zofunika kwambiri mu makina owongolera kutentha kwambiri. Ntchito yawo imakhazikika mu Peltier effect: pamene mphamvu yolunjika idutsa mu thermocouple yopangidwa ndi zinthu ziwiri zosiyana za semiconductor, kutentha kumayamwa pa malo amodzi (mbali yozizira) ndipo nthawi imodzi kumakanidwa pa malo ena osiyana (mbali yotentha).
Mu machitidwe owongolera kutentha ophatikizidwa, ma module a thermoelectric, ma module a peltier, ma TEC amagwirizanitsidwa ndi owongolera kutentha anzeru (monga ma thermostat) kuti athe kulamulira kutentha kwa mbali ziwiri, kogwira ntchito, komanso kotsekedwa molondola kwambiri. Pansipa pali kusanthula kolinganizidwa kwa mfundo zawo zogwirira ntchito ndi momwe zimagwiritsidwira ntchito:
1. Mfundo yaikulu yogwirira ntchito: Kulamulira kutentha kwa mbali ziwiri zotsekedwa
Module yoziziritsira ya Thermoelectric, TEC imagwira ntchito ngati chipangizo chosamutsira kutentha chokha ndipo singathe kudziwa yokha ngati kuziziritsa kapena kutentha; luso lopanga zisankho limeneli lili mkati mwa chowongolera kutentha—“gawo loyendetsera pakati” la dongosololi. Chokhala ndi sensa yotenthetsera yodalirika kwambiri, chowongoleracho chimayang'anira kutentha kwenikweni ndikuyerekeza ndi malo omwe ogwiritsa ntchito amasankha:
• Njira Yoziziritsira: Pamene kutentha komwe kwayesedwa kwapitirira malo apamwamba, wolamulira amagwiritsa ntchito mphamvu yolowera kutsogolo, zomwe zimapangitsa kuti kutentha kutuluke kwambiri kumbali yozizira.
• Kutentha: Kutentha kukatsika pansi pa malo otsika, chowongolera chimabweza polarity yamagetsi, potero chimasintha ntchito za kutentha za malo awiriwa ndikuyambitsa kutentha kogwira ntchito.
Njira yosinthira mphamvu yamagetsi iyi imalola kusintha kwa kutentha nthawi yomweyo—popanda kuchedwa kwa makina kapena kusakhala ndi mphamvu ya kutentha—motero imapereka yankho labwino kwambiri poyerekeza ndi makina oziziritsira omwe amadalira zinthu zotenthetsera zosiyana ndikuwonetsa kuchedwa kwa makina.
2. Ma domain oyimira mapulogalamu
Chifukwa cha kulimba kwawo pang'ono, kugwira ntchito mwakachetechete, kugwira ntchito kosagwedezeka, komanso kukhazikika kwa kutentha (kukwaniritsa kulondola kwa ±0.1 °C, ndi kutsika mpaka ±0.01 °C muzokonzedwe zabwino), makina oyendetsera kutentha a Thermoelectric module (peltier cooler) TEC amagwiritsidwa ntchito kwambiri m'magawo ofunikira kwambiri:
• Sayansi ya zachipatala ndi zamoyo: Ma thermal cycler a Polymerase chain reaction (PCR), ma gene sequencers a m'badwo wotsatira, ma chemical analyzer a clinical biochemical, ndi ma trainer otengera katemera omwe amakhudzidwa ndi kutentha—zonsezi zimafuna kufanana kwa kutentha kuti zitsimikizire kuti mayeso ndi otetezeka kwa odwala.
• Makina a kuwala ndi a photonic: Ma laser diode, masensa owonera, ndi zowunikira za infrared, komwe kusinthasintha kwa kutentha kwa mphindi kumayambitsa kusuntha kwa wavelength kapena kusokoneza njira ya kuwala; Chifukwa chake, kukhazikika kwa TEC kolondola ndikofunikira kuti zizindikiro zisunge kukhulupirika mu kulumikizana kwa kuwala ndi metrology ya pamwamba pa ma optics olondola kwambiri.
• Kupanga mafakitale ndi ma semiconductor: Photolithography steppers, zida zolembera plasma, ma ADAS imaging modules, ndi ma LiDAR transceivers—kumene kukhazikika kwa kutentha kumalamulira mwachindunji kubwerezabwereza kwa njira, kukolola, ndi kudalirika kwa zida kwa nthawi yayitali pansi pa mikhalidwe yosinthasintha.
• Zipangizo zamagetsi ndi zonyamulika: Ma module oyendetsera kutentha kwa mafoni, zochotsera chinyezi pogwiritsa ntchito condensation, ma miniaturized refrigeration units, ndi zipangizo zoziziritsira khungu—zimapereka mayankho a kutentha chete, opanda firiji, komanso oteteza chilengedwe.
3. Ma subsystem ofunikira omwe amalola kuti TEC igwire bwino ntchito
Kuti mugwiritse ntchito bwino mphamvu za ma module a peltier, zida za peltier, ndi ma TEC mkati mwa kapangidwe kowongolera kutentha, njira zingapo zodalirana ziyenera kukonzedwa bwino ndikukonzedwa bwino:
• Kuwongolera mayankho pogwiritsa ntchito PID: Popeza mphamvu ya kutentha ndi mphamvu yamagetsi yosakhala ya mzere wamagetsi ndi mphamvu yamagetsi yosakhala ya mzere wamagetsi ya TEC, ma cooler a peltier, ma algorithms a peltier advanced proportional-integral-derivative (PID) amagwiritsidwa ntchito kusintha mphamvu yamagetsi yoyendetsa, kuchotsa cholakwika cha steady-state, kuletsa kusinthasintha kwa kutentha, ndikusunga ntchito yeniyeni ya isothermal.
• Kusamalira kutentha kwa mbali yotentha pogwiritsa ntchito mphamvu zambiri: Popeza ma TEC amagwira ntchito ngati mapampu otenthetsera—osati ma heat sinks—kutaya bwino kutentha kwa zinyalala kuchokera mbali yotentha n'kofunika kwambiri. Kulephera kwa dongosolo nthawi zambiri kumayamba chifukwa cha kuzizira kosakwanira mbali yotentha; chifukwa chake, ma heat sinks a aluminiyamu kapena mkuwa okhala ndi mphamvu zambiri, owonjezeredwa ndi kukakamiza mpweya kapena malo ozizira amadzimadzi, ndi njira yodziwika bwino.
• Kuzindikira kutentha molondola kwambiri: Kuyeza molondola kumadalira masensa okonzedwa bwino monga ma thermistors a NTC kapena ma thermometers a PT100 platinum resistance. Kuti muchepetse kukana kwa kutentha ndikuwonetsetsa kuti pali mayankho ofanana, masensa ayenera kuyikidwa mwakuthupi pamalo olamulidwa ndi kutentha—nthawi zambiri otetezedwa pogwiritsa ntchito mafuta a silicone oyendetsera kutentha komanso okhazikika mwamakina.
• Chitetezo chokwanira: Zowongolera kutentha zolimba zimaphatikizapo chitetezo cha zigawo zambiri—kuphatikizapo overcurrent, overvoltage, overtemperature, ndi short-circuit—kuti achepetse zoopsa zokhudzana ndi zochitika za reverse voltage zosakhalitsa, kutentha komwe kumachoka, kapena zinthu zosazolowereka zomwe zingasokoneze Thermoelectric module, TEC module, TEC lifelong kapena chitetezo cha makina.
4. Kuyerekeza: Ubwino ndi zopinga
Ubwino:
• Kapangidwe kolimba kamachotsa ziwalo zosuntha, kuonetsetsa kuti sizikugwira ntchito bwino, sizikukonzedwanso, komanso nthawi yayitali yogwirira ntchito;
• Chinthu cholimba kwambiri chomwe chimathandiza kuti zinthu zigwirizane ndi malo ochepa;
• Kutembenuka kwachangu kwa kutentha kumathandiza kuti ntchito ya agile igwire ntchito pa kutentha kwakukulu (monga −50 °C mpaka +80 °C);
• Kapangidwe kopanda firiji kakugwirizana ndi malamulo apadziko lonse lapansi okhudza chilengedwe komanso zolinga zosamalira chilengedwe.
Zoletsa:
• Kuchuluka kwa magwiridwe antchito (COP), makamaka pa kutentha kwakukulu;
• Mphamvu yayikulu yoziziritsira imachepetsedwa kwambiri ndi mphamvu yokana kutentha mbali yotentha;
• Kugwiritsa ntchito mphamvu kumawonjezeka kwambiri pamikhalidwe yovuta kwambiri ya ΔT;
• Ma module a TEC amphamvu kwambiri (ma module a thermoelectric) amatanthauza ndalama zambiri zopangira zinthu ndi kupanga, zomwe zimakhudza chuma cha dongosolo lonse.
