Problems solved by technology

[0006] However, if the number of rotations of the cooling fan is increased to increase the supply capacity of cooling air to increase the volume of air when a malfunctioning mounting unit is taken out from the electronic device, noise and power will be increased.
Also, the cooling fan is expected to have a blowing capacity suitable for maximizing the volume of air, so using a high-performance motor capable of high-speed rotation, the large size and high price of the cooling fan are disadvantageous
[0007] In addition, when the shielding plate is mounted on the case, the case itself has a mounting structure for mounting the shielding plate, so restrictions on the structure of the case tend to occur

Embodiment Construction

[0048] Embodiments are described in detail below using drawings based on specific examples. Note that the same constituent members are described with the same reference numerals. In addition, although the mounting unit is described in the embodiment as an electronic instrument accommodated in a groove of a housing of an electronic device, examples of the electronic equipment may include a printed circuit board in addition to the mounting unit accommodated in the housing. and hard disk drive.

[0049] In addition, although the number of installation units is described as being small in the embodiment for convenience, the number of installation units accommodated in the housing is not particularly limited.

[0050] Figure 1A It is a perspective view of an example of the electronic device 1 installed with the installation unit 10, which is the electronic instrument of the embodiment. Figure 1B for Figure 1A A side cross-sectional view of the electronic device 1 depicted in ....

Abstract

The present invention discloses an electronic device, comprising: a plurality of slots capable of installing a plurality of electronic instruments; and an electronic instrument inserted in any one of the plurality of slots; wherein, the electronic instrument includes a flow limiting member, The flow restricting member protrudes to the side of the adjacent slot where no electronic equipment is installed and restricts the flow of cooling air flowing through the adjacent slot. The invention also discloses an electronic instrument.

Description

technical field [0001] The embodiments discussed herein relate to an electronic device and an electronic instrument thereof. Background technique [0002] In the related art, there is an electronic device in which a plurality of electronic instruments or rack-mounted electronic units (hereinafter referred to as mounting units) having the same height and width are arranged on a dedicated shelf for storage (which may be referred to as a shelf and below referred to in the text as the shell). In such an electronic device, the mounting unit serves to be arranged horizontally in the longitudinal direction of the case or vertically in the horizontal direction. [0003] In an air-cooled electronic device, in order to maintain a normal cooling state of each mounting unit, cooling air is properly supplied to each mounting unit in a uniform manner. However, when the mounting unit is taken out from the electronic device for repair or replacement, a large amount of cooling air flows in...
