Tšebeliso ea li-module tsa peltier, li-module tsa thermoelectric ho balaoli ba mocheso

Mojule oa ho pholisa oa thermoelectric (element ea peltier)—o tsejoang hangata e le li-thermoelectric cooler (TECs)—ke likarolo tsa bohlokoa litsamaisong tsa taolo ea mocheso o nepahetseng haholo. Ts'ebetso ea tsona e thehiloe phellong ea Peltier: ha motlakase o tobileng o feta thermocouple e entsoeng ke thepa e 'meli e fapaneng ea semiconductor, mocheso o monngoa sebakeng se le seng (lehlakoreng le batang) 'me ka nako e le' ngoe o haneloa sebakeng se fapaneng (lehlakoreng le chesang).

Litsamaisong tse kopaneng tsa taolo ea mocheso, li-module tsa thermoelectric, li-module tsa peltier, li-TEC li kopantsoe le balaoli ba mocheso ba bohlale (ke hore, li-thermostat) ho nolofalletsa taolo ea mocheso ea mahlakore a mabeli, e sebetsang, le e koetsoeng ka ho nepahala ho ikhethang. Ka tlase ke tlhahlobo e hlophisitsoeng ea melao-motheo ea bona ea ts'ebetso le ts'ebetsong e sebetsang:

1. Molao-motheo oa ts'ebetso ea mantlha: Taolo ea mocheso ea selika-likoe se koetsoeng

Mojule oa ho pholisa oa Thermoelectric, TEC e sebetsa feela e le sesebelisoa sa phetisetso ea mocheso 'me e ke ke ea iketsetsa qeto ea hore na e pholise kapa e futhumatse; bokhoni bona ba ho etsa liqeto bo lula ka botlalo ka har'a molaoli oa mocheso - "yuniti e bohareng ea ts'ebetso" ea sistimi. E hlomelitsoe ka sensor ea mocheso e tšepahalang haholo, molaoli o lula a lekola mocheso oa 'nete 'me o o bapisa le li-setpoint tse hlalositsoeng ke mosebelisi:

• Mokhoa oa ho pholisa: Ha mocheso o lekantsoeng o feta ntlha e ka holimo, molaoli o sebelisa motlakase o sekametseng pele, o eketsa ho ntšoa ha mocheso ka lehlakoreng le batang.

• Mokhoa oa ho futhumatsa: Ha mocheso o theohela ka tlase ho ntlha e ka tlase, molaoli o fetola polarity ea hona joale, ka hona o fetola mesebetsi ea mocheso ea li-conjunction tse peli le ho qala ho futhumatsa ka mafolofolo.

Mokhoa ona oa ho fetola motlakase oa hona joale o nolofalletsa ho fetola mocheso ka mokhoa o batlang o le hang-hang—ntle le ho lieha ha mechine kapa ho se sebetse hantle ha mocheso—ka hona o fana ka karabelo e matla haholo ha e bapisoa le litsamaiso tsa sehatsetsi tse tloaelehileng tse itšetlehileng ka likarolo tse arohaneng tsa ho futhumatsa 'me li bontša tieho ea mechine e tloaelehileng.

2. Libaka tsa kopo tse emelang

Ka lebaka la mohato oa tsona o moqotetsane, ts'ebetso e khutsitseng, ts'ebetso e se nang ho thothomela, le botsitso ba mocheso (ho fihlella ho nepahala ha taolo ea ±0.1 °C, le ho theohela ho ±0.01 °C litlhophisong tse ntlafalitsoeng), litsamaiso tsa taolo ea mocheso tse thehiloeng ho TEC tsa module ea Thermoelectric (peltier cooler) li sebelisoa haholo mafapheng a bohlokoa a sepheo:

• Saense ea bongaka le ea bophelo: Li-cyclers tsa mocheso tsa Polymerase chain reaction (PCR), li-gene sequencer tsa moloko o latelang, li-chemical analyzer tsa kliniki, le lijana tsa lipalangoang tsa ente tse utloang mocheso—kaofela li hloka ho tšoana ho tiileng ha mocheso ho netefatsa botšepehi ba tlhahlobo le polokeho ea mokuli.

• Litsamaiso tsa mahlo le tsa photonic: Li-diode tsa laser, li-sensor tsa mahlo, le li-detector tsa infrared, moo ho feto-fetoha ha mocheso oa motsotsoana ho bakang ho kheloha ha bolelele ba leqhubu kapa ho sotha tsela ea mahlo; ka hona, ho tsitsisa TEC ka nepo hoa hlokahala bakeng sa ho boloka botšepehi ba lets'oao puisanong ea mahlo le metrology ea bokaholimo ba li-optics tse nepahetseng haholo.

• Tlhahiso ea indasteri le ea semiconductor: Li-stepper tsa Photolithography, lisebelisoa tsa ho fata ka plasma, li-module tsa litšoantšo tsa ADAS, le li-transceiver tsa LiDAR—moo botsitso ba mocheso bo laolang ka kotloloho ho pheta-pheta ha ts'ebetso, chai, le ts'epo ea lisebelisoa tsa nako e telele tlas'a maemo a feto-fetohang a tikoloho.

• Lisebelisoa tsa elektroniki le tse nkehang habobebe tsa bareki: Li-module tsa taolo ea mocheso oa li-smartphone, li-dehumidifier tse nyane tse thehiloeng ho condensation, li-unit tsa sehatsetsi tse nyane, le lisebelisoa tsa khatello ea serame sa letlalo—li fana ka litharollo tsa mocheso tse khutsitseng, tse se nang sehatsetsing le tse tšoarellang tikolohong.

3. Litsamaiso tse nyane tsa bohlokoa tse nolofalletsang ts'ebetso e ntle ka ho fetisisa ea thermoelectric TEC

Ho sebelisa ka botlalo bokhoni ba li-module tsa peltier, lisebelisoa tsa peltier, li-TEC ka har'a meralo ea taolo ea mocheso, litsamaiso tse 'maloa tse itšetlehileng ka tse ling li tlameha ho etsoa ka mokhoa o tiileng le ho ntlafatsoa hammoho:

• Taolo ea maikutlo e thehiloeng ho PID: Ka lebaka la ho se sebetse hantle ha mocheso le litšobotsi tsa phetisetso ea mocheso tse seng tsa linear tsa TEC, li-cooler tsa peltier, li-algorithms tsa modules tsa peltier tse tsoetseng pele tse nang le proportional-integral-derivative (PID) li sebelisoa ho fetola motlakase oa drive ka mokhoa o feto-fetohang, ho felisa phoso ea boemo bo tsitsitseng, ho thibela ho sisinyeha ha mocheso, le ho boloka ts'ebetso ea 'nete ea isothermal.

• Taolo ea mocheso o sebetsang hantle haholo lehlakoreng le chesang: Kaha li-TEC li sebetsa e le lipompo tsa mocheso—eseng li-heat sink—ho qhala mocheso o litšila ka katleho ho tsoa lehlakoreng le chesang ke habohlokoa haholo. Ho hloleha ha sistimi hangata ho bakoa ke ho pholisa ho sa lekaneng lehlakoreng le chesang; ka hona, li-heat sink tsa aluminium kapa tsa koporo tse nang le conductivity e phahameng, tse ekelitsoeng ke ho khannoa ha moea ka matla kapa li-loop tsa ho pholisa metsi, ke mokhoa o tloaelehileng.

• Ho lemoha mocheso ka ho nepahala ho hoholo: Tekanyo e nepahetseng e itshetlehile ka di-sensor tse lekantsweng jwalo ka di-thermistors tsa NTC kapa di-thermometer tsa kganyetso ya platinum tsa PT100. Ho fokotsa kganyetso ya sebopeho sa mocheso le ho netefatsa maikutlo a emelang, di-sensor di lokela ho kenngwa ka mmele kamanong e haufi ya mocheso le bokahodimo bo laolwang—hangata di tiisetswa ka ho sebedisa grease ya silicone e tsamaisang mocheso le ho tsitsiswa ka mechini.

• Tšireletso e felletseng ea potoloho: Balaoli ba mocheso ba matla ba kenyelletsa tšireletso ea mekhahlelo e mengata—ho kenyeletsoa le ts'ireletso ea motlakase o fetang, motlakase o feteletseng, mocheso o fetang, le potoloho e khuts'oane—ho fokotsa likotsi tse amanang le liketsahalo tsa motlakase o khutlelang morao ka nakoana, ho baleha ha mocheso, kapa maemo a sa tloaelehang a ts'ebetso a ka behang module ea Thermoelectric kotsing, module ea TEC, bophelo bo bolelele ba TEC kapa polokeho ea sistimi kotsing.

4. Tlhahlobo ea papiso: Melemo le lithibelo

Melemo:

• Kaho ea boemo bo tiileng e felisa likarolo tse tsamaeang, e netefatsa ts'ebetso e khutsitseng, ha e hloke tlhokomelo, 'me e nka nako e telele ea ts'ebeletso;

• Sebopeho se ka atolosoang haholo se tšehetsa ho kopanngoa ha liforomo tse nang le sebaka se fokolang;

• Ho fetoha ha polarity ea mocheso ka potlako ho nolofalletsa ts'ebetso ea agile ho pholletsa le maemo a pharaletseng a mocheso (mohlala, −50 °C ho isa ho +80 °C);

• Moralo o se nang sehatsetsing o tsamaisana le melaoana ea lefats'e ea tikoloho le lipheo tsa botsitso.

Meeli:

• Koefficient e tlase haholo ea ts'ebetso (COP), haholo-holo tlas'a liphapang tse kholo tsa mocheso;

• Bokgoni bo phahameng ba ho phodisa bo thibelwa haholo ke bokgoni ba ho hana mocheso lehlakoreng le chesang;

• Tšebeliso ea matla e eketseha haholo maemong a feteletseng a ΔT;

• Di-module tsa TEC tse nang le matla a maholo (di-module tsa thermoelectric) di kenyelletsa ditjeo tse phahameng tsa thepa le tlhahiso, tse amang moruo wa sistimi ka kakaretso.
