He aha ngā rauemi o te radiator?
E rua ngā momo matua o ngā whakamahana waka: ko te konumohe me te parahi, ko te tuatahi mō ngā waka pāhihi whānui, ko te tuarua mō ngā waka arumoni nunui.
Kei te tere te whanaketanga o ngā rauemi me ngā hangarau hanga o ngā pūwero waka. Me ōna painga mārama i roto i ngā rauemi mama, i roto i te mara o ngā waka me ngā waka māmā, ka whakakapia haeretia te pūwero parahi i roto i te mara o ngā waka me ngā waka māmā i te wā kotahi, kua tino whanakehia te hangarau me te tukanga hanga pūwero parahi, he mārama ngā painga o te pūwero parahi i roto i ngā waka pāhihi, ngā mīhini hanga, ngā taraka taumaha me ētahi atu pūwero miihini. Ko ngā pūwero o ngā waka ke he pūwero konumohe te nuinga, mai i te tirohanga tiaki taiao (ina koa i Ūropi me te Hononga o Amerika). I roto i ngā waka hou o Ūropi, ko te ōwehenga o ngā pūwero konumohe he toharite o te 64%. Mai i te tirohanga whanaketanga o te hanga pūwero waka i Haina, kei te piki haere haere te pūwero konumohe i hangaia e te whakapuru. Ka whakamahia hoki ngā pūwero parahi whakapuru i roto i ngā pahi, ngā taraka me ētahi atu taputapu hangarau.
