Abstract
A heat recovery wheel for a heat exchanger includes a wheel rim defining an outer perimeter of the heat recovery wheel, and a plurality of wheel passages located between the wheel rim and the wheel axis. The plurality of wheel passages are at least partially defined by one or more passage fins. At least a portion of a passage fin of the plurality of passage fins extends non-parallel to the wheel axis between a first wheel end and a second wheel end. The plurality of wheel passages are configured for flow of a first airflow and a second airflow therethrough for thermal energy exchange between the first airflow and the second airflow.
Claims20
A heat exchanger, comprising:
- a housing, the housing defining:
- a first airflow chamber through which a first airflow is directed;
- and
- a second airflow chamber through which a second airflow is directed;
- and
- a heat recovery wheel disposed in the housing and rotatable about a wheel axis, the heat recovery wheel including:
- a wheel rim defining an outer perimeter of the heat recovery wheel;
- and
- a plurality of wheel passages located between the wheel rim and the wheel axis, the plurality of wheel passages at least partially defined by one or more passage fins, at least a portion of a passage fin of the plurality of passage fins extending non-parallel to the wheel axis between a first wheel end of the heat recovery wheel and a second wheel end of the heat recovery wheel;
- wherein the plurality of wheel passages are configured for flow of the first airflow and the second airflow therethrough for thermal energy exchange between the first airflow and the second airflow.
