Power tool with fan duct for printed circuit board

A power tool comprising

• an electrically powerable drive unit;
• circuitry for controlling a supply of electrical energy to the electrically powerable drive unit;
• a housing assembly including:
• a generally longitudinal enclosure with a first interior volume for containing the electrically powerable drive unit, and
• a handle enclosure with a second interior volume for containing the circuitry, the handle enclosure extending generally perpendicularly with respect to the generally longitudinal enclosure proximate to a first end of the generally longitudinal enclosure, the second interior volume of the handle enclosure in fluid communication with the first interior volume of the generally longitudinal enclosure;
• an air mover disposed within the housing assembly at the first end of the generally longitudinal enclosure proximate to the handle enclosure, the air mover configured to direct air from outside of the housing assembly at the first end of the housing assembly into the housing assembly, and then to direct the air generally perpendicularly to a longitudinally extending direction of the generally longitudinal enclosure;
• and
• a duct adjacent to and in fluid communication with the air mover at the first end of the generally longitudinal enclosure to direct the air from the air mover into the handle enclosure and toward the circuitry, the duct including:
• an inflow segment having a first axis and defining a first area for receiving the air from the air mover,
• an outflow segment having a second axis and defining a second area for directing the air from the air mover toward the circuitry, and
• a connecting segment connecting the inflow segment to the outflow segment, the first area of the inflow segment axially offset from the second area of the outflow segment by the connecting segment, the first axis of the inflow segment and the second axis of the outflow segment each extending generally parallel to one another and generally perpendicularly with respect to the generally longitudinal enclosure, wherein at least one of the first area of the inflow segment or the second area of the outflow segment is generally rectangular-shaped, and an axis of the connecting segment is angled with respect to an axis of the inflow segment and an axis of the outflow segment when viewed from both a first orientation facing a short side of the at least one rectangular-shaped area and from a second orientation facing a long side of the at least one rectangular-shaped area.
