Dab tsi yog tus tiv thaiv thermal?

2024-10-29

Nyob rau hauv lub intricate ntiaj teb ntawm cov khoom siv hluav taws xob, kev nyab xeeb kev ua haujlwm hauv kev ua kom muaj kev phom sij, tiv thaiv kev phom sij muaj xws li kev kub ntxhov thiab hluav taws kub. Ntawm cov khoom siv kev nyab xeeb no,Cov Tiv Thaiv ThermalSawv ntsug los ua ib feem tseem ceeb, tshwj xeeb hauv cov motors. Yog li, dab tsi yog tus tiv thaiv thermal, thiab nws ua haujlwm li cas rau Safeeguard Motors los ntawm Thermal Khiav?

Txhais thiab Lub Hom Phiaj

A Tus Tiv Thaiv Thermalyog cov khoom siv nyab xeeb tshwj xeeb tau tsim rau cov motors saib xyuas thiab tswj lawv qhov kub thiab txias. Nws lub luag haujlwm tseem ceeb yog kom kaw cov hluav taws xob ntxiv rau lub cev muaj zog thaum nws pom tias lub cev muaj zog tau nce mus rau cov qib tsis zoo. Qhov no tsis siv neeg disconnection txwv tsis pub muaj lub cev muaj zog los ntawm kev ua haujlwm hauv qab ntau cov kev mob kub, uas tau txo lub neej, lossis txawm tias kev puas tsuaj tsis zoo li hluav taws.


Kev tso menyuam hauv sab hauv thiab kev siv tshuab

Thermal tiv thaiv tau muab tso rau hauv sab hauv, feem ntau nyob ze rau cov windings lossis lwm yam tseem ceeb ntawm kev kub ntxhov. Qhov kev tso cai no tso cai rau tus tiv thaiv kom ntsuas qhov ntsuas kub kom raug thiab teb nrawm.


Lub tshuab ua haujlwm ntawm cov tiv thaiv tus mob thermal yog qhov ncaj tsis tau muaj txiaj ntsig zoo. Nws feem ntau muaj cov khoom siv hluav taws xob rhiab, xws li ib lub bimetallic sawb lossis ib lub thermoplastic caij, uas hloov pauv cov khoom ntiag tug thaum ua kom sov. Raws li lub cev muaj zog kub sab, cov ntaub ntawv rhiab nthuav dav lossis khoov, ua kom lub zog hloov uas tsis sib haum lub zog. Thaum lub cev muaj zog txias, cov ntaub ntawv rov qab mus rau nws thawj lub xeev, tso cai rau tus tiv thaiv rov pib dua thiab lub cev ua kom muaj kev hloov pauv tau.


Tseem ceeb hauv kev nyab xeeb

Qhov tseem ceeb ntawm cov tiv thaiv thermal hauv kev nyab xeeb tsis tu ncua. Cov Motors, ua kev sib xyaw ua ke ntawm cov tshuab thiab cov khoom siv, los ntawm cov cuab yeej siv rau tsev neeg cov khoom siv hauv tsev, yog yuav ua haujlwm txuas ntxiv thiab sib txawv. Sij hawm dhau mus, cov mob no tuaj yeem ua rau hnav thiab kua muag, ua rau lub cev muaj zog los ua kom sov dua li ib txwm. Yog tsis muaj tus tiv thaiv thermal, xws li overheating tuaj yeem ua kom sai, muaj peev xwm ua kom lub cev muaj zog ua kom lub cev muaj zog thiab cov phom sij loj.


Ntxiv mus, cov tiv thaiv cua sov tsis yog tiv thaiv lub cev muaj zog nws tus kheej tab sis kuj tag nrho cov kab ke uas nws ua haujlwm. Los ntawm kev tiv thaiv kev kub ntxhov, lawv pab tswj cov txiaj ntsig tag nrho thiab kev ntseeg tau ntawm cov cuab yeej siv, txo qhov xav tau ntawm kev kho kom nquag thiab hloov pauv. Qhov no, nyob rau hauv lem, ua rau cov nqi txuag tau thiab txo qis kev cuam tshuam nrog kev ua haujlwm.


Hom thiab Kev Siv

Cov Tiv Thaiv ThermalLos rau hauv ntau hom ntawv thiab tau tsim kom haum rau ntau hom kev tsav tsheb thiab cov kev siv. Qee hom hom muaj xws li:


Bimetallic thermal tiv thaiv: cov no siv cov sawb ua los ntawm ob co me nrog cov sib txawv thermal nthuav tawm coeffal. Thaum rhuab, sawb khoov, ua kom lub pob nyem.

Tus cua nab kuab no: cov no siv lub tshuab cua sov, qhov kub-lub resistor, uas nws tsis kam hloov nrog qhov kub thiab txias, kom tswj hwm lub zog.

Fuse cov kws tiv thaiv: cov no yog ib lub sijhawm siv ib zaug thiab kaw cov Circuit Court thaum muaj qhov ntsuas kub tau mus txog.

Txhua hom muaj nws qhov tshwj xeeb zoo thiab raug xaiv raws cov cai tshwj xeeb ntawm lub cev muaj zog thiab lub zog nws lub zog.
