Dab tsi yog txoj haujlwm ntawm cov thermistor diode hauv kev sib txuas lus hluav taws xob?

1. Cov ntsiab lus ntawm tus qauv ua haujlwm ntawm cov thermistor diode
Thermistor diode yog ib qho kub rhiab raws cov ntaub ntawv semiconductor, thiab nws cov kev ua haujlwm feem ntau yog nyob ntawm cov khoom kub ntawm cov ntaub ntawv kub semiconductor. Thaum qhov kub hloov pauv, cov cab kuj siab thiab kev mus ncig ntawm cov ntaub ntawv semiconductor yuav tseem hloov pauv, ua rau muaj kev hloov pauv ntawm cov thermistor diode. Raws li cov yam ntxwv ntawm kev hloov pauv nrog kub, thermal dodes tuaj yeem faib ua ob hom: Qhov zoo coefficient (PTC) thiab kub kub coefficient (NTC). NTC thermistor dodes tau siv dav hauv kev sib txuas lus lub zog.
Cov nqi tiv thaiv dhau los ntawm lub sijhawm B yog cov khoom siv tsis tu ncua ntawm cov thermistor diode. Qhov no tshwj xeeb tus yam ntxwv ua rau muaj cov cua sov NTC kom paub qhov kev hloov pauv thiab hloov chaw rau kev tswj hwm kub thiab kev tswj hwm ntawm kev sib txuas lus lub hwj chim.
2. Lub luag haujlwm tshwj xeeb ntawm thermal diodes nyob rau hauv kev sib txuas lus Hwj chim
(1) SUPPpress Surge tam sim no
Thaum cov kev sib txuas lus hluav taws xob tau pib, ib qho loj tshaj plaws tam sim no yuav tsim los vim cov nyhuv them ntawm lub tshuab lim dej. Qhov kev tawm tsam no tsis yog tsuas yog ua rau muaj kev puas tsuaj rau cov hluav taws xob hauv lub zog hluav taws xob, tab sis kuj tseem yuav cuam tshuam rau kev ua haujlwm ruaj khov ntawm tag nrho cov kev sib txuas lus. NTC tus cua sov ua kom pom qhov tseem ceeb ntawm lub zog pib thaum lub zog pib}}}}}}} Zoo rau kev cuam tshuam ntawm surge spurents.
Thaum lub zog tig mus, qhov kub ntawm NTC thermistor diode yog tsawg, uas muaj cov nyhuv muaj zog rau cov nyhuv tam sim no thiab txwv qhov tseem ceeb ntawm surge tam sim no. Nrog rau kev ua haujlwm ib txwm ntawm lub zog module, cov NTC thermistor diode heats li maj mam poob, txo qhov kev cuam tshuam ntawm qhov haujlwm tam sim no thiab tsis cuam tshuam rau kev ua haujlwm ib txwm muaj ntawm lub zog module. Piv txwv li, hauv qee qhov kev sib txuas lus me me, txuas ib qho teeb tsa NTC thermistor diode nyob rau hauv series nyob rau hauv series nyob rau hauv series nyob rau hauv series nyob rau hauv series nyob rau hauv series nyob rau hauv series nyob rau hauv surge diodes hauv lub zog module los ntawm kev puas tsuaj.
(2) ntsuas ntsuas kub thiab them nyiaj
Cov kev sib txuas lus hluav taws xob tsim hluav taws xob tsim kom muaj qee qhov kev ua haujlwm, thiab kev hloov pauv kub tuaj yeem cuam tshuam kev ua haujlwm thiab kev ruaj ntseg ntawm lub zog module. NTC cov cua sov tuaj yeem ua cov ntsuas kub kom sov los saib xyuas tiag tiag- sov hloov hauv lub zog fais fab. Los ntsuas ntsuas tus nqi tiv thaiv ntawm NTC thermistor diode thiab raws li kev tawm tsam kub cov xeeb cuj, qhov kub ntawm lub zog module tuaj yeem suav tau raug yog.
Tib lub sijhawm, cov yam kub ntawm cov thermistor diode kuj tseem siv tau los them rau qhov kub ntawm lub zog module. Hauv lub hwj chim module, kev ua yeeb yam ntawm cov hluav taws xob hluav taws xob yuav drift nrog cov kev hloov pauv ntawm qhov kub thiab txias ntawm cov neeg tiv thaiv kev tiv thaiv. Los ntawm kev qhia NTC thermistor diodes rau hauv lub voj voog thiab kho cov khoom siv hluav taws xob tau them nyiaj rau hauv tiag tiag, thiab qhov ntsuas qhov chaw ruaj khov thiab qhov tseeb ntawm lub zog module tuaj yeem txhim kho. Piv txwv li, hauv qee qhov siab- precision sib txuas lus lub zog uas raug them nyiaj rau cov zis hluav taws xob muaj peev xwm ua kom cov zis hluav taws xob muaj peev xwm ua kom lub zog hluav taws xob ruaj khov tshaj qhov ntau qhov kub.
(3) Kev tiv thaiv overheating
Thaum cov kev sib txuas lus hluav taws xob tau ua rau muaj kev phom sij thiab kub thiab txias dua
Nruab ntc thermistor diode ntawm lub zog tseem ceeb ntawm lub zog module los soj ntsuam qhov ntsuas kub nyob hauv lub sijhawm. Thaum qhov ntsuas kub tshaj qhov teeb tsa kev nyab xeeb, tus nqi tiv thaiv kab mob hluav taws xob txo qis qis, yog li kev puas tsuaj los ntawm kev puas tsuaj los ntawm overheating. Piv txwv li, hauv qee qhov kev sib txuas lus loj hauv paus chaw nres tsheb loj, NTC thermistor dodes yog siv rau kev tiv thaiv overheating. Thaum qhov kub ntawm lub zog hluav taws xob ntau dua 80 degree, kev tiv thaiv kev nyab xeeb ntau dhau los, txiav tawm cov khoom siv fais fab thiab kom muaj kev nyab xeeb ntawm cov khoom siv sib txuas lus.
