Patent ID: 7530385

Claim:
A rotary-type total heat exchanger comprising: a pair of blowers for providing a first airflow and a second airflow into the total heat exchanger, respectively; a rotary wheel defining therein a plurality of air passageways, and upon rotation, the rotary wheel being capable of exchanging heat and moisture between the airflows when the airflows separately flow though the air passageways of the rotary wheel; an air-guiding member in fluid communication with one blower for guiding one of the airflows toward the rotary wheel; and an air-regulating member located between the rotary wheel and the air-guiding member for distributing the guided airflow over the air passageways of the rotary wheel; wherein the air-regulating member is connected to an air-exiting end of the air-guiding member, the air-regulating member includes a solid bottom portion and a mesh-like top portion, the top portion defines therein a network of openings for passage of the guided airflow and divides the guided airflow into many smaller airflows, and the bottom portion has a thickness gradually reduced toward the top portion to form a slope for guiding the guided airflow to move toward the top portion.
