Lub npe "heat bridge" yog ib qhov samsam rau "thermal bridge" thiab suav sib piv los pab txhais lub teeb meem tshuaj tsho nyob hauv qex tsev. Nws txhais tau tias ib qhov cim lossis qhov chaw uas muaj kev sib txuas ntau dua li cov khoom nyob ze, tsim ib qhov kheej los sib txuas nrog lub tsev. Qhov siv "heat bridge" txhais tias muaj kev sib txuas ntawm hluv (thermal energy) los ntawm qhov no. Tswv yim feem ntau nyob hauv qex tsev: duab ntim thiab duab rooj uas sib txuas nrog hauv thiab nraud, duab consrete uas tsis muaj insulation uas tsim qhov balcony, duab I-beams uas nyob hauv duab insulation, thiab duab ties nyob hauv duab cavity walls. Cov khoom no, vim tias muaj thermal conductivity siab, yog qhov sib txuas los hluv tsha kom tshaug nyob hnub ci mus lossis tsha kom sov nyob hnub sov mus. Qhov kev phem yog tib yam li thermal bridge: kev siv ntau dua rau kev tshaug lossis sov, kev txo qhov temperature hauv qhov chaw, thiab muaj kev puag ncig tshaug thiab tuaj sau ntxhiab. Lub npe no txhais tias qhov chaw no yog ib qhov sib txuas rau kev tshaug uas tsis xav tau, thiab kev paub thiab kho qhov no yog qhov tseem ceeb rau kev tsim thiab qex tsev zoo. Yuav hu li cas los xav rau thermal bridge lossis heat bridge, qhov tseem ceeb yog kev tsim kho los ntawm thermal breaks thiab continuous insulation kom tso qhov kev tshaug uas tsis xav tau.
