Yuav Siv Thermocouples li cas txhawm rau txheeb xyuas qhov tsis sib xws hauv cov pwm kub khiav?

Kev tsis sib xws yog qhov teeb meem tshwm sim hauv cov pwm kub khiav uas ua rau muaj teeb meem zoo xws li warpage, dab dej, thiab qhov sib txawv ntawm qhov sib txawv. Thermocouples, ob qho tib si nyob rau hauv qhov kub khiav thiab lub tshuab cua txias, tuaj yeem siv los kuaj thiab kuaj xyuas tus mob no. Thawj qhov qhia txog qhov tsis sib xws yog qhov kub thiab txias ntawm thaj chaw. Yog hais tias qhov kub khiav thermocouples qhia tias ib cheeb tsam yuav tsum muaj qhov feem pua ​​​​ntawm lub zog ntau dua los tswj qhov teeb tsa, nws yuav yog vim tias cheeb tsam ntawd tau txias dua los ntawm cov kab txias. Qhov thib ob qhia yog qhov kub "droop" thaum lub caij txias. Tom qab kev txhaj tshuaj tiav, lub taub hau ntawm lub taub hau yuav tsum poob ntawm tus nqi sib xws. Yog tias ib cheeb tsam poob nrawm dua li lwm tus, nws qhia tau tias qhov txias txias ua haujlwm zoo dua hauv cheeb tsam ntawd. Qhov thib peb kauj ruam yog siv cov thermocouples ntxiv hauv cov kab dej txias. Nruab cov thermocouple sensors rau ntawm qhov nkag thiab qhov hluav taws xob ntawm txhua qhov cua txias. Qhov kub thiab txias sib txawv ntawm qhov hluav taws xob thiab qhov hluav taws xob qhia tau hais tias lub tshuab cua txias yog nqus cua sov, uas yog qhov qub. Txawm li cas los xij, yog tias ib lub voj voog muaj qhov sib txawv ntawm qhov kub thiab txias dua li lwm tus, nws qhia tias qhov cua txias tsis sib xws. Cov kauj ruam thib plaub yog ua qhov "txias-kev sim." Tso tseg kev tsim khoom, tua cov dej txias, thiab saib xyuas cov kub khiav thermocouple nyeem thaum pwm txias. Thaj chaw uas txias tshaj plaws yog qhov cuam tshuam tshaj plaws los ntawm cov dej txias. Kauj ruam tsib yog siv lub koob yees duab thermal. Thaum tsis yog thermocouple, lub koob yees duab thermal muab ib daim duab qhia pom ntawm pwm qhov kub thiab txias. Sib piv cov duab thermal nrog cov ntaub ntawv thermocouple kom paub meej tias cov hotspots lossis qhov chaw txias. Cov kauj ruam thib rau yog txhawm rau txheeb cov ntaub ntawv thermocouple nrog ib feem zoo. Yog hais tias ib cheeb tsam ib txwm tsim cov khoom nrog warpage lossis dab dej, thiab nws cov thermocouple qhia qhov sib txawv ntawm qhov sib txawv, qhov txuas tau tsim. Kauj ruam xya yog los kho cov dej txias ntws. Yog hais tias ib cheeb tsam yog overcooled, txo tus nqi ntws mus rau hauv Circuit Court, los yog ua kom cov dej kub. Yog hais tias ib cheeb tsam yog undercooled, nce qhov ntws. Cov ntaub ntawv thermocouple muab cov lus tawm tswv yim los ua cov kev hloov kho no. Kauj ruam yim yog siv "zoned cooling." Nyob rau hauv cov pwm nyuaj, siv cais cov cua txias rau txhua qhov chaw, thiab kho qhov ntws raws li cov ntaub ntawv thermocouple. Los ntawm kev sib koom ua ke cov ntaub ntawv thermocouple rau hauv kev tswj kom txias, cov pwm tuaj yeem kuaj xyuas thiab kho qhov tsis sib xws, txhim kho qhov zoo thiab txo cov khoom seem.
