Kev daws (Los ntawm Pab Pawg Examveda) Cov kauj ruam hauv qab no yog siv los txo cov thermal tsis kam: Nyob rau hauv conduction, txo cov thickness ntawm cov khoom thiab nce hauv thermal conductivity. Nyob rau hauv convection, nplawm cov kua thiab ntxuav lub cua sov saum npoo.
Yuav ua li cas thiaj txo tau cov thermal resistance?
Vim li ntawd, cov kws tsim khoom yuav tsum nrhiav txoj hauv kev los txo qhov thermal tiv thaiv los ntawm cov khoom siv hluav taws xob sib txuas mus rau huab cua ambient. Yog li ntawd, ib txoj hauv kev los txo Rja yog txo Rcs, kev tiv thaiv kev tiv thaiv ntawm cov khoom siv hluav taws xob thiab ambient-txias, finned cua sov dab dej lossis cov kua dej txias txias
Yuav ua li cas ua rau thermal resistance?
Tus lej tsawg thiab qhov loj ntawm cov chaw sib cuag tau ua rau thaj chaw tiv tauj tiag tiaguas yog qhov me dua li thaj chaw sib cuag. Qhov chaw tiv tauj tsawg no ua rau muaj kev tiv thaiv thermal, tiv thaiv kev tiv thaiv lossis kev tiv thaiv thermal.
Dab tsi cuam tshuam rau thermal conduction?
Cov txheej txheem ntawm kev ua kom sov yog nyob ntawm plaub yam tseem ceeb: qhov kub thiab txias, ntu ntu ntawm cov khoom cuam tshuam, lawv txoj kev ntev, thiab cov khoom ntawm cov ntaub ntawv.
Puas yog qhov hloov pauv thermal hloov nrog qhov kub?
Rau hluav taws xob tam sim no txhais tau tias tig hluav taws xob mus rau hauv tshav kub. Tab sis rau thermal conduction nws zoo li tig cov cua sov tam sim no rau hauv tshav kub. Kev sib tsoo ntawm ions thiab electrons pab ua kom sov. Yog vim li cas thermal resistance txo nrog kub.
