Te whakamāramatanga o te kawe wera: Ko te tikanga ka tohuhia e te tohu "λ", ā, ko te waeine ko: Watt/mita·tohu (W/(m·K), ka taea te whakakapi i te K ki te ℃. Ko te kawe wera (e mōhiotia ana ko te kawe wera, ko te kawe wera rānei) he ine i te kawe wera o tētahi rauemi. Ka whakaahua i te kawe wera o tētahi rauemi i raro i ngā āhuatanga whakawhiti wera pumau (i raro i ngā āhuatanga whakawhiti wera pumau, ko te rauemi he 1 mita te matotoru, me te rerekētanga pāmahana o te 1 tohu i ngā taha e rua, ka whakawhiti i te wera mā roto i te rohe o te 1 mita tapawha i roto i te 1 hēkona). E tohu ana ko te kawe wera tētahi o ngā āhuatanga ā-tinana me te matū o te rauemi tonu, ā, e pā ana ki te momo, te āhua (hau, wai, totoka) me ngā āhuatanga (pāmahana, pēhanga, haumākū, me ētahi atu) o te rauemi. I roto i ngā tau, ko te kawe wera he rite ki te mātotoru rere wera i hangaia e te whakahekenga o roto o tētahi mea i raro i te mahi a te rōnaki waeine. He rerekē ngā uara kawe wera o ngā rauemi rerekē. Mō ngā rauemi whakamahana, ko te teitei ake o te kawe wera, ko te kino ake o te mahi whakamahana. I te nuinga o te wā, he nui ake te kawe wera o ngā totoka i te wai. he nui ake i tērā o ngā hau.
Ko te tauwehenga reti mākū µ he tawhā e whakaatu ana i te kaha o te rauemi ki te ātete i te urunga o te kohu wai, ā, he rahinga kore-ahu. Ko te waeine ko m, ko te tikanga he ōrite ki te urunga o te kohu wai o te hau o m. E whakaahua ana i te mahi a te rauemi, ehara i te mahi a te hua, te hanganga rānei.
Mō ngā rauemi whakamarumaru he rite tonu te kawe wera tīmatanga K engari he rerekē te µ, ka nui ake te uaua o te urunga o te mamaoa wai ki roto i te rauemi ki te teitei ake o te uara µ, nō reira ka puhoi ake te pikinga o te kawe wera, ā, ka roa ake te wā e rahua ai te whakamarumaru, ka roa ake hoki te ora mahi.
Ina iti iho te uara µ, ka poto ake te wā ka eke te kawe wera ki te uara rahunga nā te tere o te urunga o te mamaoa wai. Nō reira, ko te matotoru hoahoa matotoru anake ka taea te whakatutuki i te roa o te ora ratonga rite ki ngā rauemi uara µ teitei.
He nui ngā tauwehenga reti mākū e whakamahia ana e ngā hua Jinfulai hei whakarite i te pumau o te kawe wera, nō reira, mā te matotoru tīmatanga angiangi ka roa te ora.
He aha te whanaungatanga i waenga i te kawe wera me te tauwehe reti mākū o te rauemi whakamahana?
