Thermal resistance yog qhov feem ntau siv ntsuas kub ntsuas hauv nruab nrab mus rau qhov kub tsawg

Thermal resistance yog qhov feem ntau siv ntsuas kub ntsuas hauv nruab nrab mus rau qhov kub tsawg. Platinum kub tsis kam muaj qhov ntsuas qhov tseeb tshaj plaws, thiab nws tsis yog tsuas yog siv dav hauv kev ntsuas kub, tab sis kuj tau ua rau hauv cov ntsuas ntsuas tus qauv. Nws cov yam ntxwv tseem ceeb yog qhov ntsuas qhov tseeb thiab kev ua haujlwm ruaj khov.

1. Cov ntsiab lus thiab cov ntaub ntawv ntawm kev ntsuas qhov kub thiab txias

Thermal resistance temperature ntsuas yog raws li tus yam ntxwv uas tus nqi kuj ntawm ib tug hlau conductor nce nrog rau qhov nce ntawm qhov kub thiab txias rau qhov ntsuas kub.

Feem ntau cov thermal resistors yog ua los ntawm cov khoom siv hlau ntshiab, nrog platinum thiab tooj liab feem ntau siv. Tsis tas li ntawd, cov ntaub ntawv xws li platinum, npib tsib xee, manganese, thiab rhodium tau siv los tsim cov thermal resistors.

2. Kev sib xyaw ntawm qhov ntsuas kub ntawm qhov ntsuas kub tsis kam

Ib qho kev ntsuas qhov ntsuas kub ntawm qhov ntsuas kub feem ntau muaj cov thermal tsis kam, txuas cov xov hlau, thiab cov cuab yeej tso saib. Ob lub ntsiab lus hauv qab no yuav tsum tau sau tseg:

① Cov lej kawm tiav ntawm cov thermal resistor thiab cov cuab yeej tso saib yuav tsum zoo ib yam

② Txhawm rau tshem tawm qhov cuam tshuam ntawm kev hloov pauv ntawm qhov kev tiv thaiv ntawm cov xov hlau sib txuas, yuav tsum tau siv peb txoj kev sib txuas.

Cov khoom tawg-pov thawj thermoelectric resistor siv cov qauv tshwj xeeb ntawm lub thawv sib txuas los txuas cov sib xyaw tawg hauv nws cov casing vim muaj kev cuam tshuam ntawm sparks lossis arcs.

Kev kho ntawm qhov qhib Circuit Court ntawm lub cev resistor inevitably yuav tsum tau hloov qhov ntev ntawm lub resistor hlau thiab cuam tshuam tus nqi kuj. Yog li ntawd, nws yog qhov zoo dua los hloov lub cev resistor nrog ib qho tshiab. Yog siv vuam siv, nws yuav tsum tau xyuas kom tsim nyog tom qab vuam ua ntej siv
