Abstract
An apparatus may include a host circuit board supporting a heat-producing electronic component, a rotor for an axial flux motor, and fan blades supported by the rotor. The host circuit board may include traces forming windings for the axial flux motor. The rotor may be supported by and rotatable relative to the host circuit board to generate a flow of cooling fluid to cool the first heat-producing electronic component.
Claims30
An apparatus, comprising:
- a host circuit board including one or more traces forming one or more windings for an axial flux motor, the one or more windings being configured to generate first magnetic flux within an active region of the axial flux motor when energized with current;
- at least a first heat-producing electronic component supported by the host circuit board;
- a rotor for the axial flux motor, the rotor being supported by and rotatable relative to the host circuit board, the rotor being configured to generate second magnetic flux within the active region;
- and
- one or more fan blades supported by the rotor to generate a flow of cooling fluid to cool the first heat-producing electronic component.
2 more elements
A method, comprising:
- attaching at least a first heat-producing electronic component to a host circuit board that includes one or more traces forming one or more windings for an axial flux motor, the one or more windings being configured to generate first magnetic flux within an active region of the axial flux motor when energized with current;
- and
- attaching a rotor for the axial flux motor to the host circuit board so that the rotor is rotatable relative to the host circuit board, the rotor being configured to generate second magnetic flux within the active region and including one or more fan blades to generate a flow of cooling fluid to cool the first heat-producing electronic component.
