Description

  The present invention relates to a cooling structure for a rack mount type electronic device.

  FIG. 5 is an exploded perspective view of a mounting example of a conventional electronic device apparatus in a rack-mounted electronic device cooling structure.

  Since rack-mounted electronic devices have multiple electronic devices mounted vertically in a single rack cabinet, the cooling structure is basically opened by the cooling fan mounted inside the front opening of electronic device 2. The air is sucked from 3 and exhausted from the rear opening 4.

  The electronic device 2 is mounted on the rack cabinet column 1 by a conventional mounting bracket 13 via a conventional slide rail 12 that can be pulled out so that maintenance can be performed while mounted on the rack cabinet.

  The conventional mounting bracket 13 includes a conventional front bracket 13a and a conventional rear bracket 13b, and has a slidable structure so that it can be mounted in accordance with the interval between the front and rear columns 1 of the rack cabinet.

  In the above-described mounting form, a plurality of interface connectors are provided on the back of the device, and as the electronic device 2 becomes thinner, it is difficult to secure a sufficient back opening 4 for cooling the inside of the electronic device 2. Yes.

  In addition, with high-density mounting in the electronic device 2, it has become difficult to secure a flow path for efficiently flowing cooling air from the front surface to the back surface inside the electronic device 2.

  For this reason, if you cannot secure a sufficient exhaust opening on the back of the device, or if you cannot efficiently secure a cooling air flow path from the front to the back, and you want to exhaust the air on the way, exhaust the air to the side of the electronic device 2. However, since the height of the electronic device 2 is low in the conventional mounting form, the conventional slide rail 12 and the conventional mounting bracket 13 cover the side surface of the electronic device 2, and the exhaust I could not do it.

  In addition, it is possible to exhaust air from the side of the device because the height of the electronic device 2 is high or the conventional slide rail 12 and the conventional mounting bracket 13 are provided lower than the height of the electronic device 2. Even in such a case, heat accumulates in the space between the front and rear posts 1 of the rack cabinet, and the internal temperature of the rack cabinet rises. This reduces the performance and reliability of the electronic components in the electronic device 2 and shortens the service life. Cause problems.

  Further, due to the rise in the internal temperature of the rack cabinet, there is a risk that the air whose temperature has risen will enter the intake side of the electronic device 2 and further raise the internal temperature of the electronic device 2.

  Therefore, when exhausting from the side surface of the electronic device 2, the exhausted air must be promptly guided to the back side of the electronic device 2 by an air duct or the like.

  A cooling structure of a rack mount type electronic device using such an air duct is described in Japanese Patent Application Laid-Open No. 2000-277956. However, in the above publication, an air duct is attached to the front and rear columns of the rack cabinet to guide the air discharged from the side of the electronic device to the back of the device. However, in the case of a device with a low electronic device height, the mounting bracket is There is a problem that the duct is not attached because the height of the apparatus is the same.

  Further, since the air duct is attached from the side of the rack cabinet, there is a problem that the attachment is difficult when the rack cabinets are connected.

  In addition, rack cabinets generally have four columns, and the front and rear frontage dimensions, the distance between the left and right mounting holes, and the vertical mounting hole pitch of each column are standardized. Since the interval between the columns and the shape of the columns vary depending on each rack manufacturer, when the air duct is mounted on the side of the rack cabinet, the shape of the mounting portion must be changed according to the various rack cabinets. In addition, some rack cabinets do not have an attachment portion from the side surface, and therefore there is a problem that the air duct itself cannot be attached.

JP 2000-277956 A

  The problem to be solved is that the rack mount type electronic equipment with low height enables the side exhaust of the air after cooling the inside of the equipment and the internal temperature of the rack cabinet rises, and the mounted rack mount type The purpose is to prevent the performance deterioration of electronic components in the electronic equipment, the deterioration of reliability, and the shortening of the service life.

  The present invention provides a rack-mounted electronic device having an opening coinciding with a side opening of the electronic device on a slide rail or mounting bracket for mounting the same, and forming a cylindrical duct by the mounting bracket. The air exhausted from the device side is easily exhausted to the back of the electronic device.

  According to the present invention, the mounting bracket is made into a cylindrical duct, so that the side exhaust of the electronic device can be raised to the internal temperature of the rack cabinet in a form equivalent to a general rack mounting without adding special parts. There is an advantage that can be realized without doing.

  Further, by providing the slide rail that can be pulled out with the opening on the side surface of the electronic device and the opening of the mounting bracket, there is an advantage that it is possible to exhaust the side surface of the electronic device with a low height.

  In addition, there is an advantage that the mounting portion on the back side of the mounting bracket can be mounted on various rack cabinets in which the distance between the front and rear columns of the rack cabinet is different by adjusting the length.

  As a method of realizing side exhaust of rack mount type electronic equipment while preventing the internal temperature rise of the rack cabinet, it was realized in the same form as the conventional mounting method.

FIG. 2 is a perspective view of a slide rail in an extended state according to an embodiment of the present invention. FIG. 3 is a mounting perspective view of a mounting bracket according to an embodiment of the present invention on a rack cabinet. FIG. 4 is a perspective view of a rack-mount type electronic device that is an embodiment of the present invention in a pulled-out state.

  The electronic device 2 has a cooling structure that sucks air from the front opening 3 and exhausts air from the back opening 4 and the side opening 5.

  The electronic device 2 is mounted on the rack cabinet column 1 by a mounting bracket 8 via a slide rail 6 that can be pulled out.

  The slide rail 6 includes an outer member 6a, an inner member 6b, and a drawer member 6c, and is configured to be slidable in the longitudinal direction. Each member has a slide rail stored in the side opening 5 of the electronic device 2. A slide rail opening 7 is provided so as to penetrate the matching position.

  The mounting bracket 8 includes a front bracket 8a and a rear bracket 8b, and threaded portions 11 for attaching to the rack cabinet column 1 are provided at both ends. The front bracket 8a is formed in a cylindrical shape, and the opposite surface side of the screw portion 11 is in an open state. The length is longer than the depth dimension of the electronic device 2. A bracket air inlet 9 is provided on the mounting surface of the slide rail 6 at a position matching the slide rail opening 7. The rear bracket 8b is formed in a U-shape, and is inserted so that the opposite side of the screw portion 11 can slide into the cylindrical shape of the front bracket 8a. Thereby, the bracket exhaust port 10 is formed.

  The mounting bracket 8 is attached to the front and rear columns 1 of the rack cabinet by the screw portions 11 at both ends. At this time, the front bracket 8a and the rear bracket 8b slide so that they can be mounted in accordance with the distance between the front and rear columns 1. The outer member 6a of the slide rail 6 is attached to the front bracket 8a, and the drawer member 6c is attached to the side surface of the electronic device 2. Thus, the electronic device 2 is mounted in a state where it can be pulled out from the rack cabinet.

  When the electronic device 2 is in the stowed state, the air discharged from the side opening 5 passes through the slide rail opening 7 of the slide rail 6 and enters the mounting bracket 8 from the bracket inlet 9, and the rear bracket 8b The air is exhausted from the bracket exhaust port 10 formed in the shape.

  With this mounting form, there is an effect that the side exhaust of the electronic device can be led to the back of the device in a form equivalent to mounting of a general rack mount electronic device. Further, since the mounting bracket 8 is mounted so that the length thereof can be adjusted, there is an effect that the mounting bracket 8 can be mounted on rack cabinets having different intervals between the front and rear columns 1. Further, since the length of the front bracket 8a is secured to be equal to or greater than the depth of the electronic device 2, the bracket exhaust port 10 is always formed on the back side of the electronic device 2.

  It can be applied to mounting of a rack mount type electronic device having a side exhaust.
