1. An electronic apparatus comprising:
- a circuit board;
a frame formed by a plate having a size corresponding to the circuit board or a size larger than the size corresponding the circuit board and covering the circuit board, the circuit board being fixed to the frame;
a cooling fan located on an opposite side of the circuit board across the frame and attached to the frame, the cooling fan configured to rotate around a column-like stator that is directly attached to the plate of the frame with a rotation axis that overlaps a point at which the cooling fan is attached to the frame;
an air flow path on the frame through which air discharged from the cooling fan passes;
a cover having a shape for covering the air flow path and define a wall of the air flow path together with the frame; and
a heat sink disposed inside the cover,wherein the rotation axis is perpendicular to the circuit board,wherein the air flow path is formed in an outer circumference of the cooling fan,wherein the cooling fan includes a plurality of fins arranged in a circumferential direction around the column-like stator,wherein the column-like stator includes a disk-like bottom portion having a fixed hole for attaching the column-like stator to the frame, and thedisk-like portion is located on an interior of the plurality of fins near the rotation axis.

Abstract
Provided is an electronic apparatus including a cooling fan and a cover configuring an outer wall of an air flow path and having a heat sink arranged therein, and effectively utilizing a frame as a member for heat radiation.
A cooling fan 40 is arranged on the opposite side of a circuit board across an upper frame 20 and attached to the upper frame 20. The electronic apparatus includes a cover having a shape for covering the air flow path and defining a wall of the air flow path together with the upper frame 20. Heat sinks 61 and 62 are arranged on the inner side of the cover 50.

15. An electronic apparatus comprising:
-
a circuit board; a frame formed by a plate and covering the circuit board and attached to the circuit board; a cooling fan arranged on the frame, the cooling fan including a column-like stator arranged at a center of the cooling fan, wherein the column-like stator includes a disk-like bottom portion having a fixed hole for attaching the column-like stator directly to the plate of the frame, and the disk-like portion is located on an interior of the plurality of fins near a rotation axis of the cooling fan, wherein the rotation axis of the cooling fan is along a thickness direction of the circuit board, the rotation axis overlapping the fixed hole point at which the column-like stator is attached to the frame; and a projection projecting from the disk-like portion toward a top surface of the frame to secure a clearance between cooling fan and the frame. - View Dependent Claims (16, 17)
