Description

  The present invention relates to a rack-mount type electronic device storage box for mainly storing units of electronic devices such as information communication devices.

  The rack mount type electronic device storage box is provided with a U-shaped mount unit for mounting a unit inside a box as shown in Patent Document 1, and a plurality of electronic device units are arranged in parallel with the mount unit. It has a structure that can be attached.

  Since such a unit generates a large amount of heat from the internal electronic devices, the inside of the unit will become hot if it is not dissipated, resulting in malfunctions such as device failure and reduced life. In particular, information communication equipment generates a lot of heat, and if the equipment that serves as the backbone of the communication network goes down, the impact becomes very large.

  Therefore, conventionally, as shown in FIG. 8, each unit 1 is provided with an exhaust fan 2 to cool the inside of the unit, but the mount unit 3 is disposed at a position that prevents smooth exhaust from these exhaust fans 2. In many cases, the mounting unit 3 is provided with the slit 4 to reduce the airflow resistance, but a sufficient cooling effect may not be obtained. Although it is conceivable to reduce the size of the mount unit 3, since the structural strength is required to support the unit of the heavy electronic device, the mount unit 3 is small enough not to prevent smooth exhaust from the exhaust fan 2. It is not easy to make it.

Further, even if the exhaust from the exhaust fan 2 of the unit 1 is successfully performed, the exhaust fills the inside of the box body 5, so that heat remains and prevents the unit 1 from being sufficiently cooled. In order to solve this problem, it is a general solution to attach a ventilation fan to the box 5 and exhaust the internal air. However, the cost increases, noise due to the noise of the ventilation fan, possibility of failure, periodic Disadvantages such as the need for proper maintenance.

  The present invention solves the above-mentioned conventional problems, allows the exhaust from the unit attached to the mount unit to be performed smoothly, and provides an excellent cooling effect without attaching a ventilation fan to the box. It was made to provide equipment storage boxes.

  The present invention made to solve the above problems is a rack-mount type electronic device storage box provided with a U-shaped mounting unit for mounting a unit inside a box, wherein the mounting unit has a unit mounting piece. An exhaust duct for passing exhaust from the unit is configured, and the tip thereof is communicated with an exhaust port formed in the wall surface of the box. In addition, it is preferable that the exhaust duct is provided with an opening at a position corresponding to the exhaust fan of the unit, and the exhaust duct is preferably provided with a slide part that can be expanded and contracted at the tip thereof.

  The rack mount type electronic device storage box of the present invention comprises an exhaust duct that allows exhaust from the unit to pass through the unit mounting piece of the mount unit, and its tip communicated with an exhaust port formed on the wall surface of the box. High-temperature exhaust generated by the heat generated by the electronic equipment inside the unit is guided to an exhaust port formed on the wall surface of the box through the exhaust duct of the mount unit, and is discharged to the outside of the box. This ensures that the unit is cooled. Moreover, even if a ventilation fan is not attached to the box, heat does not accumulate inside the box.

Hereinafter, preferred embodiments of the present invention will be described.
In FIG. 1, 10 is a box body of a rack mount type electronic device storage box of the present invention, and 11 is a door thereof. A mount unit 12 is installed inside the box 10. As shown in FIG. 2, the mount unit 12 includes a unit mounting piece 13 at the bottom, a side plate 14, and a unit mounting piece 15 at the top, and is U-shaped when viewed from the side. As shown in FIGS. 3 and 4, a plurality of units 16, 16 can be attached between 15. Exhaust fans 17 and 17 for cooling the inside of the units are provided on the upper surfaces of the units 16 and 16.

  In the present embodiment, an exhaust duct 18 is formed above the upper unit mounting piece 15. The exhaust duct 18 may be provided integrally with the unit mounting piece 15 or may be provided separately. The exhaust duct 18 is for passing exhaust from the exhaust fans 17 and 17 of the units 16 and 16, and an opening 19 is formed at a position corresponding to the exhaust fan 17 of the unit 16.

  The exhaust duct 18 extends toward the wall surface of the box 10 and communicates with an exhaust port 20 formed on the wall surface. The installation position of the exhaust port 20 is not particularly limited, but there are many cases such as a ceiling or wall of a building on the upper part or the left and right side walls of the box body 10, so the exhaust port 20 is formed in the front door 11. It is preferable to keep it. In this embodiment, an exhaust port 20 is formed in the door 11, and a hood 21 is provided on the outside thereof to prevent rainwater from entering.

  In the rack-mounted electronic device storage box of the present invention configured as described above, the heat generated inside the unit 16 enters the exhaust duct 18 from the exhaust fan 17 to above the unit mounting piece 15 and enters the wall surface of the box 10. It is discharged to the outside from the formed exhaust port 20. Since the exhaust duct 18 has a cylindrical shape surrounded by the periphery, sufficient exhaust can be performed only by the exhaust fan 17 of the unit 16, and heat does not accumulate inside the box body 10.

  This structure can be manufactured at a relatively low cost because the conventional mount unit 12 is simply enlarged to install a duct. Moreover, since it is not necessary to provide a ventilation fan in the box 10, it is possible to avoid disadvantages such as an increase in cost due to the installation of the ventilation fan, noise due to the operation sound of the ventilation fan, the possibility of failure, and the necessity of regular maintenance.

  However, when the amount of heat generation is particularly large, such as when the number of units 16 is large, an auxiliary ventilation fan 22 can be provided on the end face of the exhaust duct 18 as shown in FIG. However, even in this case, the auxiliary ventilation fan 22 can exhibit a sufficient effect even if it is downsized as compared with the case where it is attached to the box 10.

  In addition, as shown in FIG. 6, the exhaust duct 18 may be inclined so that the tip is widened so that the exhaust can be more easily removed.

  In addition, as shown in FIG. 7, an extendable slide portion 23 is added to the tip of the exhaust duct 18, so that the same device can cope with the case 10 having different depth dimensions.

  As described above, according to the present invention, exhaust from the unit 16 attached to the mount unit 12 can be performed smoothly, and an excellent cooling effect can be obtained without attaching a ventilation fan to the box 10. It is also possible to take a soundproofing measure by attaching a sound absorbing material or a temperature raising device to the exhaust duct 18.
