Daim ntawv thov ntawm peltier modules, thermoelectric modules hauv cov tswj kub

Cov khoom siv cua txias thermoelectric (peltier element) - feem ntau hu ua thermoelectric coolers (TECs) - yog cov khoom tseem ceeb hauv cov txheej txheem tswj kub siab. Lawv txoj haujlwm yog grounded nyob rau hauv Peltier effect: thaum ib qho tam sim no ncaj qha hla lub thermocouple tsim los ntawm ob lub semiconductor cov ntaub ntawv sib txawv, cua sov raug nqus ntawm ib qho kev sib tshuam (sab txias) thiab tib lub sijhawm tsis lees txais ntawm qhov sib tshuam (sab kub).

Hauv cov txheej txheem tswj kub sib xyaw ua ke, cov thermoelectric modules, peltier modules, TECs tau txuas nrog cov tswj kub ntse (piv txwv li, thermostats) kom ua rau muaj kev tswj hwm kub bidirectional, nquag, thiab kaw-loop nrog qhov tseeb tshwj xeeb. Hauv qab no yog kev tshuaj xyuas cov qauv ntawm lawv cov hauv paus ntsiab lus ua haujlwm thiab kev siv ua haujlwm:

1. Lub hauv paus ntsiab lus ua haujlwm: Kev tswj hwm thermal bidirectional kaw-voj

Ib lub thermoelectric cooling module, TEC ua haujlwm tsuas yog ib lub cuab yeej hloov cua sov thiab tsis tuaj yeem txiav txim siab seb puas yuav txias lossis cua sov; qhov kev txiav txim siab no nyob hauv lub tshuab tswj qhov kub thiab txias - lub kaw lus "chav ua haujlwm hauv nruab nrab." Nruab nrog lub sensor kub siab, lub tshuab tswj xyuas tas li saib xyuas qhov kub thiab txias tiag tiag thiab piv rau cov chaw teeb tsa uas tus neeg siv tau teev tseg:

• Hom txias: Thaum qhov kub ntsuas tau siab tshaj qhov teev tseg sab saud, lub maub los siv hluav taws xob mus tom ntej, ua kom qhov kub rho tawm ntawm sab txias siab tshaj plaws.

• Hom cua sov: Thaum qhov kub poob qis dua qhov chaw teeb tsa qis dua, tus maub los yuav thim rov qab qhov polarity tam sim no, yog li ntawd hloov pauv lub luag haujlwm thermal ntawm ob qhov kev sib txuas thiab pib ua kom sov nquag.

Lub tshuab hloov tam sim no ua rau muaj kev hloov pauv hom thermal ze li sai tau - tsis muaj mechanical latency lossis thermal inertia - yog li muab cov lus teb dynamic zoo dua piv rau cov tshuab tub yees ib txwm muaj uas vam khom cov khoom cua sov sib cais thiab qhia txog kev ncua sijhawm kho tshuab.

2. Cov npe ntawm cov ntawv thov sawv cev

Vim lawv qhov chaw me me, kev ua haujlwm ntsiag to, kev ua haujlwm tsis muaj kev co, thiab qhov kub thiab txias ruaj khov (ua tiav qhov kev tswj hwm qhov tseeb ntawm ± 0.1 ° C, thiab nqis mus rau ± 0.01 ° C hauv cov kev teeb tsa zoo tshaj plaws), Thermoelectric module (peltier cooler) TEC-based thermal management systems tau siv dav thoob plaws cov haujlwm tseem ceeb:

• Kev kho mob thiab kev tshawb fawb txog lub neej: Cov tshuab ua kom lub cev muaj zog polymerase chain reaction (PCR), cov tshuab ua kom cov noob caj noob ces tshiab, cov tshuab ntsuas tshuaj lom neeg hauv tsev kho mob, thiab cov thawv thauj cov tshuaj tiv thaiv kab mob uas rhiab rau qhov kub thiab txias—txhua yam no yuav tsum tau ua kom muaj kev sib npaug ntawm qhov kub thiab txias kom ntseeg tau tias kev kuaj mob zoo thiab kev nyab xeeb ntawm tus neeg mob.

• Cov tshuab kho qhov muag thiab cov tshuab photonic: Laser diodes, cov khoom siv kho qhov muag, thiab cov khoom siv infrared detectors, qhov twg qhov kub thiab txias hloov pauv me ntsis ua rau muaj qhov wavelength drift lossis optical path distortion; yog li ntawd, kev ruaj khov TEC kom raug yog qhov tseem ceeb rau kev tswj hwm qhov tseeb ntawm cov teeb liab hauv kev sib txuas lus kho qhov muag thiab kev ntsuas qhov chaw ntawm cov khoom siv kho qhov muag siab.

• Kev tsim khoom lag luam thiab semiconductor: Cov steppers Photolithography, cov cuab yeej plasma etching, ADAS imaging modules, thiab LiDAR transceivers—qhov twg thermal stability tswj hwm ncaj qha rau cov txheej txheem rov ua dua, cov txiaj ntsig, thiab kev ntseeg tau ntawm cov khoom siv mus sij hawm ntev nyob rau hauv cov xwm txheej ib puag ncig sib txawv.

• Cov khoom siv hluav taws xob thiab cov khoom siv nqa tau: Cov modules tswj kev kub ntawm xov tooj ntse, cov tshuab dehumidifiers me me uas siv condensation, cov tub yees me me, thiab cov khoom siv txias uas siv dermatological—muab cov kev daws teeb meem kub uas ntsiag to, tsis muaj refrigerant, thiab ib puag ncig ruaj khov.

3. Cov kab ke tseem ceeb uas ua rau muaj kev ua tau zoo tshaj plaws ntawm thermoelectric TEC

Yuav kom siv tau tag nrho cov peev xwm ntawm peltier modules, peltier devices, TECs hauv lub tsev tswj kub, ntau lub subsystems sib txuas yuav tsum tau tsim kho thiab sib koom ua ke:

• Kev tswj hwm raws li PID: Muab qhov thermal inertia thiab nonlinear voltage-current-heat-transfer yam ntxwv ntawm TECs, peltier coolers, peltier modules advanced proportional-integral-derivative (PID) algorithms siv los kho qhov drive current, tshem tawm qhov yuam kev steady-state, suppress thermal oscillations, thiab tswj kev ua haujlwm isothermal tiag tiag.

• Kev tswj cua sov sab kub zoo: Vim tias TECs ua haujlwm zoo li cov twj tso cua sov—tsis yog cov dab dej cua sov—kev tshem tawm cov cua sov pov tseg los ntawm sab kub yog qhov tseem ceeb heev. Kev ua tsis tiav ntawm lub kaw lus feem ntau yog los ntawm kev txias sab kub tsis txaus; yog li ntawd, cov dab dej cua sov txhuas lossis tooj liab uas muaj kev coj ua siab, ntxiv los ntawm kev sib xyaw cua lossis cov voj voog txias kua, yog cov qauv kev coj ua.

• Kev ntsuas kub kom raug: Kev ntsuas kom raug yog siv cov sensors uas tau calibrated xws li NTC thermistors lossis PT100 platinum resistance thermometers. Yuav kom txo qhov tsis kam ntawm thermal interface thiab xyuas kom meej tias muaj kev tawm tswv yim zoo, cov sensors yuav tsum tau mounted rau hauv qhov sib cuag thermal nrog qhov chaw tswj hwm - feem ntau ruaj ntseg siv cov roj silicone thermally conductive thiab mechanically stabilized.

• Kev tiv thaiv kab ke uas muaj txhij txhua: Cov tswj kub uas ruaj khov muaj ntau txheej kev tiv thaiv—xws li kev tiv thaiv tam sim no dhau, kev tiv thaiv hluav taws xob ntau dhau, kev tiv thaiv kub dhau, thiab kev tiv thaiv luv luv—kom txo tau cov kev pheej hmoo uas cuam tshuam nrog cov xwm txheej hluav taws xob rov qab ib ntus, kev khiav tawm ntawm lub zog thermal, lossis cov xwm txheej ua haujlwm tsis zoo uas yuav ua rau Thermoelectric module, TEC module, TEC lub neej ntev lossis kev nyab xeeb ntawm lub kaw lus puas tsuaj.

4. Kev ntsuam xyuas sib piv: Cov txiaj ntsig thiab kev txwv

Cov txiaj ntsig:

• Kev tsim kho ruaj khov tshem tawm cov khoom txav mus los, ua kom ntseeg tau tias ua haujlwm ntsiag to, tsis muaj kev saib xyuas, thiab lub neej ua haujlwm ntev dua;
