Kev Taw qhia txog Thermoelectric txias module
Thermoelectric Technology yog ib qho txheej txheem tswj kev tswj hluav taws xob siv rau ntawm Peltier effect. Nws tau tshawb pom los ntawm JCA Peltier hauv 1834, qhov kev tshwm sim no cuam tshuam nrog cov cua sov lossis cua txias ntawm cov khoom siv thermoelectric (bismuth thiab selitturide) los ntawm kev sib tshuam tam sim no los ntawm kev sib tshuam. Thaum lub sijhawm ua haujlwm, ncaj qha tam sim no ntws los ntawm TEC Module ua rau cov cua sov kom hloov ntawm ib sab mus rau lwm sab. Tsim kev txias thiab kub sab. Yog tias cov kev taw qhia ntawm qhov tam sim no tau thim rov qab, tus mob khaub thuas thiab kub tau hloov pauv. Nws lub zog txias kuj tuaj yeem hloov kho los ntawm kev hloov nws cov haujlwm tam sim no. Ib qho ib txwm theem tom qab txias dua (daim duab txias dua 1) muaj ob lub phiaj ceramic nrog p thiab n-hom soob cov khoom (bismuth, qhia tawm) ntawm cov phiaj xwm ceramic. Cov ntsiab lus ntawm cov khoom siv semiconductor tau txuas nrog hluav taws xob hauv cov koob thiab cua sov hauv kev sib txuas.
Thermoelectric txias module, TEC Modtier ntaus ntawv, thiab vim nws qhov hnyav, nws yog qhov tsim nyog siv los ua ib feem ntawm kev ua kom txias tshuab (vim txwv ntawm qhov chaw). Nrog cov txiaj ntsig zoo xws li kev ua haujlwm ntsiag to, kev ua haujlwm ntawm lub neej, kev txhawb nqa yooj yim, kev kho mob ntau, kev kho mob, kho mob Kev Tiv Thaiv, Kev sim cov cuab yeej siv (cov khoom siv dej txias, lub tub yees txias, lub tsev so dej txias, kom pw txias, pw tsaug zog zoo nkauj, lwm yam).
Niaj hnub no, vim hais tias ntawm nws qhov hnyav me, me me lossis muaj peev xwm thiab tus nqi lag luam (xws li cov khoom lag luam muag khoom, xws li cov tub yees duab kub, portable tub yees, portable tub yees, carcooler thiab lwm yam)
