Title:
COOLING DEVICE FOR ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2023127217
Kind Code:
A
Abstract:
To send air for cooling into an electronic apparatus efficiently by a fan.SOLUTION: A cooling device 3 sends air for cooling to a heat exchange unit 249 of an electronic apparatus 2. A fan 330 is accommodated in a casing 331 and has blades 336 rotating around a blade shaft, and exhausts air taken in from fan intake ports 333, 334 from a fan exhaust port 335. Housings 37, 38 have an air supply duct 346 for sending the air exhausted from the fan exhaust port to the heat exchange unit. A direction to send the air from the air supply duct to the heat exchange unit is defined as a first direction, a surface orthogonal to the first direction as a first surface, and a surface parallel to the first direction as a second surface. The fan has a first inclination θ1 with respect to the first surface so that the fan exhaust port is closer to the heat exchange unit than the blades in the first direction, and has a second inclination θ2 around the blade shaft so that the fan exhaust port is directed inclined from a direction parallel to the second surface when seen from the first direction.SELECTED DRAWING: Figure 8
