Lub tshuab vuam ntau zaus txawv ntawm lwm lub tshuab vuam. Nws lub hom phiaj thiab kev ua haujlwm tsis yog tsuas yog vuam ib leeg xwb. Kev siv vuam ntau zaus tuaj yeem siv tsis tau tsuas yog rau vuam ntawm ntau yam ntaub ntawv hlau, tab sis kuj rau diathermy, melting, kho cua sov thiab lwm yam txheej txheem. Vuam tsuas yog ib qho ntawm nws ntau siv.
Lub hauv paus ntsiab lus ua haujlwm yog:
Ua ntej, nyob rau hauv lub tshuab high-frequency, ib txheej ntawm cov cim hluav taws xob hluav taws xob hloov hluav taws xob tsawg zaus AC kis tau los ntawm daim phiaj hluav taws xob rau hauv high-frequency AC. Tom qab lub high-frequency tam sim no ntxiv rau lub induction kauj, nws yog hloov dua siab tshiab rau hauv ib tug high-frequency magnetic teb los ntawm kev siv lub hauv paus ntsiab lus ntawm electromagnetic induction thiab ua rau cov khoom hlau nyob rau hauv lub magnetic teb. Siv cov nyhuv eddy tam sim no, ib qho induced tam sim no proportional rau lub magnetic teb siv yog generated nyob rau hauv cov khoom hlau. Qhov eddy tam sim no cuam tshuam los ntawm cov nyhuv ntawm daim tawv nqaij. Qhov ntau zaus, qhov ntau concentrated nws yog nrog rau saum npoo ntawm cov khoom hlau. Thaum eddy tam sim no ntws hauv cov khoom siv hlau, nws yuav tsim kom muaj cua sov los ntawm kev siv lub hauv paus ntsiab lus ntawm cov nyhuv thermal tam sim no nrog kev pab los ntawm qhov muaj nuj nqis tsis kam. Cov cua sov no yog tsim ncaj qha rau hauv cov khoom, yog li cov cua kub ceev ceev thiab cov efficiency siab.
