Abstract

An electronic apparatus includes a circuit board (1), an MPU (8) which is provided on the circuit board (1) and produces heat, an attachment stay (6) which is provided on the circuit board (1) and has a plurality of attachment areas, and a fan unit (7) which is attached to at least one selected from the plurality of attachment areas of the attachment device (6), and cools the MPU (8).

Description

technical field [0001] An embodiment of the present invention relates to an electronic device in which a fan unit for cooling electronic components is installed. Background technique [0002] Generally, in an electronic device such as a personal computer, an IC, an LSI, an MPU, and the like are disposed on a circuit board (hereinafter, these components are representatively referred to as "MPU"). In order to process various multimedia information such as characters, sounds, and images, the processing speed and functions of the MPU have been continuously enhanced. [0003] Meanwhile, in the MPU, as integration density develops and functions increase, power consumption also increases, and heat generated during operation also tends to increase accordingly. [0004] In order to improve the heat radiation of the MPU, a motor-driven fan unit is provided inside the device (see Japanese Patent Application Laid-Open Publication No. 2000-13070). [0005] However, in the related art, ...
