Peltier phenomenon: Ob qhov sib txawv conductors tau txuas nrog rau ob peb galvanic thiab txuas nrog DC fais fab mov. Thaum ib qho tam sim no ntws los ntawm ob peb galvanic, qhov tshwm sim ntawm lub zog hloov pauv yuav tshwm sim, ib qho kev sib koom ua ke tawm cua sov thiab kub, thiab lwm qhov sib koom ua ke nqus cua sov thiab txias, qhov tshwm sim no hu ua Peltier nyhuv.

Cov qauv sab hauv ntawm Peltier lub caij muaj cov khoom siv semiconductor ua los ntawm N-hom thiab P-hom bismuth telluride cov ntaub ntawv. Cov chips yog cov khoom siv hluav taws xob txuas nrog hauv cov koob, tab sis nyob rau hauv ib qho kev sib txuas ntawm cov thermodynamic rau kev pom kev hloov hluav taws xob ntawm qhov ntsuas kub thiab qhov kub ntawm qhov chaw ceramic.

Thermoelectric txias yuav siv sij hawm kom zoo dua ntawm Peltier nyhuv: tshav kub yog absorbed los yog dissipated nyob rau hauv lub hlws ris ntawm ob txawv hluav taws xob conductors thaum hluav taws xob tam sim no dhau los ntawm nws. Thermoelectric modules sandwich ib Peltier lub caij nruab nrab ntawm ob lub thermally conductive ceramic daim hlau, nrog rau lub hwj huam mov uas muaj txiaj ntsig hloov hluav taws xob los ntawm lub cuab yeej los ntawm ib lub phaj ceramic mus rau lwm qhov. Tsis tas li ntawd, cov kev taw qhia ntawm cov cua sov tuaj yeem hloov pauv yooj yim los ntawm kev thim rov qab cov kev taw qhia ntawm cov dej ntws tam sim no.

Kev siv lub DC voltage ua rau cov neeg nqa khoom zoo thiab tsis zoo los nqus cov cua sov tawm ntawm qhov chaw ntawm ib lub substrate, uas tom qab ntawd xa mus rau lub substrate nyob rau sab nraud. Yog li ntawd, qhov saum npoo uas nqus lub zog yuav txias, thaum lwm sab uas tau tso tawm lub zog yuav sov.

Txhawm rau tsim kom muaj lub tshuab ua kom txias txias, Peltier module tau tsim rau hauv lub kaw lus, uas feem ntau yog tsim los ntawm ib qho thaiv ntawm cov thermal conductivity hlau (xws li aluminium alloy) thiab lub dab dej kub finned. Cov hlau thaiv yog siv los txuas cov cuab yeej kom txias, xws li laser diode lossis duab sensor, mus rau sab txias ntawm Peltier module. Lub thickness ntawm cov hlau thaiv yuav tsum raug xaiv los pab kom nws tiaj tus kom ntseeg tau tias muaj kev sib txuas ntawm thermal txuas mus rau lub phaj txias ntawm Peltier lub caij, tab sis yuav tsum paub tias cov thickness ntau dhau tuaj yeem tsim cov thermal inertia tsis tsim nyog. Txuas lub dab dej kub rau sab nraud ntawm Peltier caij txhawm rau txhawm rau tshem tawm cov cua sov rau ib puag ncig. Siv TIM rau txhua sab.

Muaj ntau ntau hom heatsink los tsim Peltier module, rau cov khoom siv hluav taws xob tsawg, cov khoom siv hluav taws xob ntau tshaj plaws yog aluminium extruded heatsink. Aluminium yog ib qho txawv tshaj plaw thermal conductor, thiab nws muaj peev xwm ua kom sov tau zoo heev; Tsis tas li txhuas muaj qee qhov zoo xws li tus nqi pheej yig, lub teeb yuag, yooj yim tsim, thiab lwm yam. cov no ua rau txhuas alloy ua cov khoom siv ntau tshaj plaws. Aluminium extruded Peltier heatsink yog qhov nrov tshaj plaws hauv kev tsim Peltier module.

Sinda Thermal yog cov chaw tsim khoom thermal, peb lub Hoobkas tau tsim muaj tshaj li 8 xyoo, peb yog cov kws tshaj lij hauv cov dab dej kub tsim thiab tsim khoom, peb tab tom tsim ntau yam ntawm cov dab dej kub xws li aluminium heat sink extrusion, skived fin heatsink, tooj liab pin fin heatsink. , aluminium zipper fin heat pipe heat sink, vapor chamber heat sink, kua txias txias phaj, thiab lwm yam rau cov neeg siv khoom thoob ntiaj teb. Sinda Thermal yog ib txwm muab kev pabcuam zoo tshaj plaws thiab zoo rau cov neeg siv khoom hauv ntiaj teb.
