Abstract
A first printed wiring board extends in the vertical direction within a first duct that extends in the vertical direction. A first axial flow fan generates airflow which absorbs heat from the first printed wiring board. Second and third ducts extends in parallel with the first duct. A fourth duct extends between the second and third ducts. A second printed wiring board extends in the horizontal direction within the fourth duct. A second axial flow fan is connected to the third duct. The second axial flow fan generates airflow which absorbs heat from the second printed wiring board. The electronic apparatus can be reduced in size.
