Kushandiswa kwema module epeltier, ma module ethermoelectric muzvinodzora tembiricha

Module yekutonhodza yeThermoelectric (peltier element)—inowanzonzi thermoelectric coolers (TECs)—izvinhu zvakakosha mumasystem ekudzora tembiricha zvine hungwaru. Kushanda kwavo kwakavakirwa paPeltier effect: kana direct current ichifamba nethermocouple yakagadzirwa nezvinhu zviviri zvakasiyana zve semiconductor, kupisa kunonyudzwa pane imwe junction (kurutivi runotonhora) uye panguva imwe chete kunorambwa pane imwe junction (kurutivi runopisa).

Mumasystem ekudzora tembiricha akabatanidzwa, mamodule ethermoelectric, mamodule epeltier, maTEC anobatanidzwa neanodzora tembiricha akangwara (kureva, mathermostat) kuti agone kudzora tembiricha yemativi maviri, inoshanda, uye yakavharwa nenzira yakarurama zvikuru. Pazasi pane ongororo yakarongwa yemitemo yavo yekushanda uye kushandiswa kwayo:

1. Nheyo huru yekushanda: Kudzora kupisa kwemativi maviri kwakavharwa-kutenderera

Iyo Thermoelectric cooling module, TEC inoshanda chete semudziyo wekutamisa kupisa uye haigone kusarudza yega kana ichitonhodza kana kupisa; kugona uku kwekusarudza kuri mukati memutongi wekupisa—“central processing unit” yesystem. Yakashongedzerwa ne sensor yekupisa yakasimba, mutongi anoramba achitarisa tembiricha chaiyo uye anoienzanisa ne setpoints dzakatsanangurwa nemushandisi:

• Kutonhodza: ​​Kana tembiricha yakayerwa ikadarika nzvimbo yepamusoro, muchina wekutonga unoisa simba remagetsi rinonanga mberi, zvichiita kuti kupisa kubudiswe zvakanyanya parutivi rwekutonhora.

• Kupisa: Kana tembiricha yadzikira pasi penzvimbo yepasi, muchina unodzora magetsi unodzosera kumashure polarity yemagetsi, nokudaro uchichinja mabasa ekupisa enzvimbo mbiri idzi uye wotanga kupisa kunoshanda.

Iyi nzira yekuchinja magetsi inogonesa kuchinja kwemamiriro ekupisa nekukurumidza—pasina kunonoka kwemagetsi kana kuti thermal inertia—zvichipa mhinduro yepamusoro-soro kana tichienzanisa nemasisitimu ekare ekutonhodza anovimba nezvinhu zvakasiyana zvekudziya uye anoratidza kunonoka kwemagetsi.

2. Madhomini ekushandisa anomiririra

Nekuda kwekushanda kwavo kwakasimba, kushanda kwavo kwakanyarara, kushanda kwavo pasina kudedera, uye kugadzikana kwekupisa (kusvika pakudzora kwakarurama kwe ±0.1 °C, uye kusvika ±0.01 °C mumagadzirirwo akagadziridzwa), Thermoelectric module (peltier cooler) TEC-based thermal management systems dzakashandiswa zvakanyanya muzvikamu zvakakosha:

• Sainzi yezvekurapa nehupenyu: Polymerase chain reaction (PCR) thermal cyclers, next-generation gene sequencers, clinical biochemical analyzers, uye ma container ekutakura majekiseni anonzwa tembiricha—zvose zvinoda kufanana kwakasimba kwekupisa kuti pave nechokwadi chekuti bvunzo dzacho dzakasimba uye murwere akachengeteka.

• Masisitimu ekuona nekuona: Laser diodes, optical sensors, uye infrared detectors, uko kushanduka kwekupisa kweminiti kunokonzera kudonha kwewavelength kana kukanganisa nzira yekuona; saka kugadzikana kwakaringana kweTEC kwakakosha pakuchengetedza kuvimbika kwechiratidzo mukutaurirana kwekuona uye metrology yepamusoro ye optics yakanyatsojeka.

• Kugadzira maindasitiri nemidziyo yemagetsi: Photolithography steppers, maturusi ekucheka plasma, ma ADAS imaging modules, uye ma LiDAR transceivers—apo kugadzikana kwekupisa kunodzora zvakananga kudzokorora kwemaitiro, goho, uye kuvimbika kwemidziyo kwenguva refu pasi pemamiriro ezvinhu anochinja-chinja.

• Zvishandiso zvemagetsi nezvinotakurika zvevatengi: mamodule ekutonga kupisa kwemafoni, zvinobvisa humidifiers zvine hunyoro, zvigadziko zvefriji zvidiki, uye zvishandiso zveganda zvinodzvinyirira kutonhora—zvichipa mhinduro dzekupisa dzakanyarara, dzisina firiji, uye dzinochengetedza nharaunda.

3. Masisitimu akakosha anoita kuti TEC ishande zvakanaka muthermoelectric

Kuti zvinyatso shandiswa kugona kwema module epeltier, zvishandiso zvepeltier, maTEC mukati mehurongwa hwekudzora tembiricha, masisitimu akati wandei anotsigirana anofanira kugadzirwa zvakanaka uye kugadziriswa pamwe chete:

• Kudzora mhinduro kwakavakirwa paPID: Zvichienderana nekushanduka kwekupisa uye hunhu hweTEC hwe nonlinear voltage-current-heat-transfer, mapeltier coolers, ma modules epeltier advanced proportional-integral-derivative (PID) anoshandiswa kugadzirisa dynamically drive current, kubvisa steady-state error, kudzvinyirira thermal oscillations, uye kuchengetedza kushanda kwechokwadi kwe isothermal.

• Kutarisira kupisa kwepadivi rinopisa zvine simba: Sezvo maTEC achishanda semapombi ekupisa—kwete madhishi ekupisa—kubvisa kupisa kwemarara kubva padivi rinopisa kunonyanya kukosha. Kukundikana kwesystem kunowanzo kukonzerwa nekutonhora kusina kukwana kwepadivi rinopisa; saka, madhishi ekupisa ealuminium kana mhangura ane conductivity yepamusoro, akawedzerwa nemhepo inomanikidzwa kana kuti mvura inotonhorera, ndiwo maitiro akajairika.

• Kunzwa tembiricha kwakanyatsojeka: Kuyera kwakarurama kunoenderana nemasensa akagadziriswa akadai seNTC thermistors kana PT100 platinum resistance thermometers. Kuti kuderedza resistance yeinterface yekupisa uye kuve nechokwadi chekuti mhinduro dzinoenderana, masensa anofanirwa kuiswa mumuviri mukati mekubatana kwekupisa kwakadzika nenzvimbo inodzorwa—kazhinji akachengetedzwa nemafuta esilicone anofambisa kupisa uye akasimbiswa nemechanically.

• Dziviriro yakakwana: Vatongi vekupisa vakasimba vanosanganisira dziviriro dzine mativi akawanda—kusanganisira over current, overvoltage, overtemperature, uye short-circuit dziviriro—kuderedza njodzi dzine chekuita nezviitiko zve transient reverse voltage, thermal runaway, kana mamiriro ekushanda asina kujairika ayo anogona kukanganisa Thermoelectric module, TEC module, TEC longevity kana system safety.

4. Kuongorora kuenzanisa: Zvakanakira nezvipingamupinyi

Zvakanakira:

• Kuvakwa kwakasimba kunobvisa zvinhu zvinofamba, zvichiita kuti pave nekushanda kwakanyarara, kusagadzirisa, uye hupenyu hwebasa hwakawedzerwa;

• Chimiro chechimiro chinokura zvikuru chinotsigira kubatanidzwa mumapuratifomu ane nzvimbo shoma;

• Kuchinja kwe polarity yekupisa nekukurumidza kunogonesa kushanda kwe agile pakati pekupisa kwakafara (semuenzaniso, −50 °C kusvika +80 °C);

• Dhizaini isina firiji inoenderana nemitemo yepasi rose yezvakatipoteredza uye zvinangwa zvekuchengetedza nharaunda.

Miganhu:

• Kushanda kwakaderera (COP), kunyanya kana tembiricha yakakura ichisiyana;

• Kukwanisa kutonhora kwakanyanya kunodzorwa zvakanyanya nekushanda zvakanaka kwekurambwa kwekupisa padivi pekupisa;

• Kushandiswa kwesimba kunowedzera zvakanyanya mumamiriro ezvinhu akaipisisa eΔT;

• Mamodule eTEC ane simba guru (thermoelectric modules) anosanganisira mitengo yakakwira yezvinhu nekugadzira, zvichikanganisa hupfumi hwese hwesystem.
