Copper vs Aluminium High- Lub Hwj Chim Lub Hwj Chim: Thermocouple Teb nrawm nrawm hauv cov txheej txheem cua sov ceev
Cov khoom siv preheating ncua sijhawm thiab kev txwv ntau lawm yog cov ntsiab lus mob hauv kev kho kom zoo dua qub. Ntau lub tuam txhab xaiv qis- nqi siab- lub zog cam khwb cia txhuas cov cua sov rau kev hloov pauv cua sov, tab sis pom tau tias qhov kub nce ceev tseem qeeb thiab cov lus qhia thermocouple ncua yog pom tseeb hauv kev ua haujlwm tiag tiag. Raws li kev sib piv cov ntaub ntawv sib piv, siab - lub zog cam khwb cia tooj liab cua sov muaj qhov zoo tseem ceeb hauv thermal conductivity, thermal teb ceev thiab qis hysteresis kev ua tau zoo piv nrog cam khwb cia txhuas cov qauv, tsim cov thermocouple dynamic tswj cov teebmeem hauv cov txheej txheem cua sov ceev.
High-lub zog cam khwb cia txhuas cov cua sov tso siab rau aluminium alloy thermal conduction, uas muaj qhov nruab nrab thermal conductivity efficiency thiab pom tseeb thermal hysteresis yam ntxwv. Cov ntaub ntawv txhuas muaj qhov kub thiab txias ceev ceev, tab sis tsis zoo nyob rau hauv lub tshav kub conduction uniformity nyob rau hauv siab - lub hwj chim instantaneous tso zis. Concentrated internal heat tsis tau diffused nyob rau hauv lub sij hawm, uas ua rau lub internal kub tsub zuj zuj thiab qeeb tag nrho kub tshuav nyiaj li cas. Nyob rau hauv cov txheej txheem cua kub ceev uas yuav tsum tau ceev kub nce thiab ceev stabilization, thermal hysteresis ua rau asynchronous qhov tseeb kub thiab teem kub. Thermocouple sensors tsis tuaj yeem ntes tau tiag tiag -lub sijhawm hloov pauv qhov kub thiab txias, ua rau muaj kev kub ntxhov hnyav thiab oscillation nyob rau theem kub nce.
High-lub zog cam khwb cia tooj liab cua sov ua kom zoo dua ntawm high-purity tooj liab ultra-siab thermal conductivity, realizing instantaneous heat diffusion thiab ceev ceev qhov kub. Copper thermal conduction efficiency yog ze li ob npaug ntawm cov ntaub ntawv aluminium alloy, uas tuaj yeem xa tawm cov cua kub ceev uas tsim los ntawm sab hauv siab - fais fab cua sov xov hlau rau cov khoom siv sib cuag. Tsis muaj cov cua sov sab hauv los yog thermal lag tshwm sim nyob rau hauv cov txheej txheem cua sov, thiab kub nce tsis tu ncua thiab synchronously. Lub ultra- thermal teb sai ua rau lub tshuab thermocouple txhawm rau taug qab qhov kub thiab txias hloov ntawm lub sijhawm tiag tiag yam tsis muaj teeb liab ncua sijhawm, paub meej meej kaw- voj kev tswj hwm hauv cov xwm txheej kub ceev.
Lub thermal stability sib txawv ntawm tooj liab thiab txhuas cov ntaub ntawv yog ntxiv amplified nyob rau hauv sib txawv load ua hauj lwm tej yam kev mob. Nyob rau hauv cov txheej txheem ntau lawm nrog nquag pib- nres thiab thauj khoom hloov pauv, cov qauv txhuas tau qeeb thermal stress tso tawm thiab pom tseeb qhov kub thiab txias inertia. Tom qab hloov hluav taws xob, qhov kub thiab txias tseem nce los yog poob rau lub sijhawm ntev, ua rau lub thermocouple kaw - voj tswj tsis yooj yim kom ruaj khov. Cov qauv tooj liab muaj qhov hloov pauv thermal teb thiab qhov ntsuas kub me me, uas tuaj yeem hloov kho sai sai rau kev hloov pauv ntawm lub zog thiab kev hloov pauv, tswj xyuas qhov ntsuas qhov ntsuas qhov tseeb thiab tswj kev ruaj ntseg.
Cov ntaub ntawv ntsuas cua kub ceev sib piv intuitively qhia kev ua haujlwm tsis zoo. Raws li lub zog sib xws thiab kev teeb tsa loj, siab - lub zog cam khwb cia txhuas cua sov siv sijhawm 185 vib nas this kom ruaj khov ntawm 320 degree, nrog qhov siab tshaj plaws thermocouple overshoot ntawm 2.1℃. High- lub zog cam khwb cia tooj liab tso cua sov ua kom ruaj khov hauv 98 vib nas this, nrog qhov siab tshaj plaws tsuas yog 0.4 degree. Nyob rau hauv 10 sib law liag pib- nres cua sov cycles, aluminium heater thermocouple qhov nruab nrab dynamic yuam kev nce mus txog 1.5 degree, thaum tooj liab rhaub yuam kev yog tswj nyob rau hauv 0.35℃.
Cov khoom siv thermal conductivity thiab hysteresis cov yam ntxwv yog cov tseem ceeb hauv kev txiav txim siab ceev cua sov ua haujlwm. Rau cov kab ntau lawm uas nrhiav kev ua haujlwm siab - ua kom muaj cua sov ua kom zoo thiab ua kom nrawm nrawm, siab - lub zog cam khwb cia tooj liab cua sov koom tes nrog siab - teb cov tshuab thermocouple kom daws tau cov teeb meem cua sov qeeb. Kev cob qhia cov khoom sib txuam thiab dynamic parameter optimization tuaj yeem ua kom muaj txiaj ntsig sai ntawm cov khoom siv.
