Rotary total heat exchange apparatus

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 through;
• a sensible heat exchanger spanning across said first and second airflows simultaneously for conducting a sensible heat exchange between the first and second airflows, wherein the sensible heat exchanger comprises a plurality of heat transfer elements thermally contacting with the first and second airflows and a plurality of spaced cooling fins attached to the heat transfer elements;
• and
• a total heat exchange wheel rotating through the first and second air passages for conducting a total heat exchange between the first and second airflows, wherein
• the total heat exchange wheel defines a plurality of air channels therein, for increasing heat exchange areas thereof, and wherein
• the rotary total heat exchange apparatus further comprises a system enclosure being divided into a first housing and a second housing by a first partition plate, the first housing contains the air-providing member therein, and the second housing receives the sensible heat exchanger and the total heat exchange wheel therein, the first partition plate diagonally defines a first and a second openings at two opposite corners thereof, the first and the second airflows enter into the second housing from the first housing through the first and the second openings, respectively, and flow through the total heat exchange wheel in a counter flow manner.
