He Kupu Whakataki ki te wāhanga whakamatao Thermoelectric
Ko te hangarau thermoelectric he tikanga whakahaere wera hohe e ahu mai ana i te pānga Peltier. I kitea e JCA Peltier i te tau 1834, ko tēnei āhuatanga ko te whakamahana, te whakamatao rānei i te hononga o ngā rauemi thermoelectric e rua (bismuth me te telluride) mā te tuku i te iahiko mā roto i te hononga. I te wā e mahi ana, ka rere te iahiko tika mā roto i te kōwae TEC ka whakawhitia te wera mai i tētahi taha ki tētahi taha. Ka hangaia he taha makariri me te taha wera. Mena ka hurihia te ahunga o te iahiko, ka rerekē ngā taha makariri me te taha wera. Ka taea hoki te whakarite i tōna mana whakamatao mā te whakarerekē i tōna iahiko whakahaere. Ko te whakamatao kotahi-wāhanga noa (Pikitia 1) he mea hanga ki ngā pereti uku e rua me te rauemi semiconductor momo-p me te momo-n (bismuth, telluride) i waenganui i ngā pereti uku. Ka honoa ngā huānga o te rauemi semiconductor mā te hiko i roto i te raupapa me te wera i roto i te whakarara.
Ka taea te whakaaro ko te waeine whakamatao hiko wera, te taputapu Peltier, ngā waeine TEC he momo papu pūngao wera totoka, ā, nā tōna taumaha, tōna rahi me te tere o te tauhohenga, he tino pai hei whakamahi hei wāhanga o ngā pūnaha whakamatao kua whakauruhia (nā te iti o te wāhi). Me ngā painga pēnei i te mahi mārire, te ātete pakaru, te ātete ru, te roa o te ora me te ngāwari o te tiaki, he whānui te whakamahinga o te waeine whakamatao hiko wera hou, te taputapu peltier, ngā waeine TEC i roto i ngā mara o ngā taputapu hōia, te rererangi, te ātea, te maimoatanga hauora, te aukati mate urutā, ngā taputapu whakamātautau, ngā hua kaihoko (te whakamatao wai, te whakamatao motuka, te pouaka whakamātao hōtēra, te whakamatao waina, te whakamatao iti whaiaro, te moenga whakamatao me te wera, me ētahi atu).
I ēnei rā, nā te iti o te taumaha, te iti o te rahi, te iti rānei o te kaha, me te iti o te utu, he whānuitia te whakamahinga o te whakamatao hiko wera i roto i ngā mahi hauora, ngā taputapu rongoā, te rererangi, te ātea, te ope taua, ngā pūnaha irahiko, me ngā hua arumoni (pēnei i te tohatoha wai wera me te matao, ngā pouaka whakamātao kawe, te pouaka whakamatao waka me ētahi atu).
