Patent ID: 7445038

Claim:
A rotary total heat exchange apparatus comprising: at least an air-providing member for providing a first airflow from outdoors and a second airflow from indoors into the rotary total heat exchange apparatus; a first air passage and a second air passage isolating from each other for guiding the first and second airflows respectively passing therethrough; and a total heat exchange wheel facing to the first and second airflows provided by the air-providing member and rotating through the first and second air passages for conducting a total heat exchange between the first and second airflows, the first and second airflows flowing through the total heat exchange wheel along a same direction, after flowing through the total heat exchange wheel, the first and second airflows flowing into two regions, respectively, the two regions being hermetically separated from each other by an air spacing member including a pair of plates inclining in different directions; wherein the air spacing member comprises a spacing plate from which the pair of plates extend toward the total heat exchange wheel; and wherein the air spacing member comprises another spacing plate connecting two adjacent sides of the pair of plates and dividing the total heat exchange wheel into two halves.
