US 12,692,871 B2 · Fan module with detachable dual-fan assembly

Abstract

A fan module for cooling electronic devices comprises a first fan and a second fan detachably coupled together. The first fan includes a first housing having latching slots, a first engagement member defining a first engagement slot with a first opening oriented toward a corresponding latching slot, and a first fan blade disposed within the first housing. The second fan includes a second housing, a second engagement member detachably fitted in the first engagement slot of the first engagement member, and a second fan blade disposed within the second housing. A latching member is disposed in the corresponding latching slots and configured to prevent the second engagement member from disengaging from the first engagement member. When assembled, the rotational axes of the fan blades are aligned to direct airflow from the first fan into the airflow path of the second fan, providing enhanced cooling performance.
