DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which shelves for accommodating a plurality of panels on which circuits are formed in parallel are stacked in multiple stages to constitute an electronic device or the like. Regarding the structure.

[0002]

2. Description of the Related Art Telecommunications equipment and other electronic equipment are constituted by a plurality of panels formed with electronic circuits arranged in parallel and accommodated in a shelf so as to be able to be inserted and removed, and the shelves are appropriately stacked in several stages. Since these panels generate heat, they need to be cooled. There is a cooling fan provided with a cooling fan for this cooling and forcibly air-cooled by passing air.

FIG. 5 is a front perspective view showing a schematic structure of a shelf rack accommodating a conventional shelf in which forced cooling is performed, with a front portion cut away. The panels 1 are accommodated in a frame (not shown) constituting the shelf 2 so as to be freely inserted and removed from the front side. The shelves 2 are stacked in two stages as shown in FIG. The frame of the shelf 2 is also housed in the shelf rack 3 so as to be able to be inserted and removed from the front side. A cooling fan 4 is provided at a lower portion of the shelf rack 3 so that air is sucked from below the shelf rack 3 and discharged upward, and the panels 1 are cooled and discharged from the upper portion of the shelf rack 3. is there. For this reason,
The panels 1 are accommodated along the ventilation direction from the lower part to the upper part of the shelf rack 3 so that adjacent panels 1 form an air flow path. In addition, for example, shelf rack 3
Is placed on a free access floor, and cooling air is sucked from between the lower part and the floor surface.

[0004] The resistance value of the channel resistance of each panel 1 differs depending on the elements and components constituting the circuit of each panel 1 or the thickness of the panel 1. Therefore, the panels 1 having a large flow path resistance and the panels 1 having a small flow path resistance can be efficiently cooled.
Are separated and accommodated in the shelf 2, and a partition plate 5 for separating them is provided in the shelf 2 in parallel with the panels 1. This partition plate 5 is provided at a position corresponding to each shelf 2.
A partition plate 6 is provided between them so that each panel can be efficiently cooled. In addition, the cooling fan 4 is also configured to be able to be inserted into and removed from the shelf rack 3 from the front side so as to easily perform a failure or maintenance.

[0005]

However, as described above, since each shelf 2 can be inserted into and removed from the shelf rack 3, there is a gap between the upper and lower shelves 2, so that Such a problem occurs.
That is, since the flow resistances of the panels 1 are different, the pressures of the cooling air supplied to the left and right portions across the partition plates 5 and 6 are different. Since the gap also exists between the partition plates 5 and between the partition plates 5 and 6, the cooling air flows from one area partitioned by the partition plate 5 to the other area due to a difference in pressure. . That is, in the area where the panels 1 with a small flow path resistance are accommodated, the flow velocity becomes large, the static pressure becomes small, and air is sucked from the area with a large flow path resistance through the gap. For this reason, the flow rate of the cooling air in the area where the flow path resistance is large is reduced, and a predetermined cooling effect may not be obtained.

In view of the above, the present invention closes the sections having different flow path resistances, suppresses the flow of air between them, improves the cooling efficiency in each section, and inserts and removes the shelf and the cooling fan. It is an object of the present invention to provide a seal structure between shelves for accommodating panels or the like which does not hinder the operation.

[0007]

As a technical means for achieving the above object, a seal structure between panels and the like for accommodating panels according to the present invention comprises a shelf for accommodating panels for insertion and removal. A cooling fan for blowing cooling air to the panels is housed in a state of being stacked in a multistage manner so as to be freely inserted into and removed from a shelf rack, and a cooling fan that is housed in the shelf rack so as to be able to be inserted into and removed from the shelf rack. In the sealing structure, a shelf inner partition plate is provided on the shelf in parallel with the panels, and one of upper and lower end portions of the shelf inner partition plate is rubbed with an elastic seal member and the other is rubbed with the seal member. Seal receiving members to be provided, respectively, and in a state where the shelf is inserted into a shelf rack, the seal member and the seal receiving member of the shelf internal partition plate positioned vertically. It is characterized by adhesion.

When the seal member and the seal receiving member are in close contact with each other, the area between the upper and lower portions of the partition plate with the partition plate interposed therebetween is blocked. For this reason, the inflow and outflow of the cooling air from the upper and lower portions of the partition plate to the adjacent area can be prevented, and a decrease in the cooling efficiency can be suppressed.

Further, since a cooling fan for blowing the cooling air is also insertable into and removable from the shelf rack, in order to prevent the inflow and outflow of air between the portions accommodating the cooling fan. The sealing structure between panels for accommodating panels and the like according to the second aspect of the present invention is such that shelves accommodating panels are removably inserted and stacked in a multi-tiered manner on a shelf rack, and cooling air is supplied to the panels.

The seal member and the seal receiving member of the partition plate located at the position (1) are in close contact with each other, and the seal member provided on the partition plate in the fan chamber and the seal receiving member provided on the partition plate in the shelf are in close contact with each other.

[0010] Since the fan accommodating sections accommodating the fans are also partitioned by the fan chamber partition plate, the adjacent sections from the cooling fan to the discharge section at the upper portion of the shelf rack are cut off, and the ventilation path for the cooling air is blocked. As a result, the cooling efficiency can be further improved.

Further, in the sealing structure between the panels for accommodating the panels and the like according to the third aspect of the present invention, the shelves accommodating the panels and the like are accommodated in a state in which the shelves accommodating the panels can be freely inserted into and removed from the shelf rack.

A seal member having elasticity is provided on one of upper and lower peripheral ends of a panel storage section partitioned by the shelf inner partition plate, and a seal receiving member for rubbing the seal member is provided on the other side. In the state where the shelf is inserted into the shelf rack, the seal members of the panel storage units positioned above and below are in close contact with the seal receiving member. It is a symptom.

Since the seal member and the seal receiving member are disposed at the upper and lower peripheral ends of the partitioned panel accommodating portion, the duct is formed by the seal member, the seal receiving member, the partition plate in the shelf, and the like. A ventilation passage having the shape of a circle is formed. Therefore, the cooling air blown from the cooling fan surely passes through the ventilation path and is discharged to the outside of the shelf rack. For this reason, the flow of air between the adjacent panel storage sections is more reliably prevented, and the cooling efficiency can be further improved.

[0013] In the seal structure between the panels for accommodating the panels and the like according to the fourth aspect of the present invention, the shelves accommodating the panels for insertion and removal are accommodated in a state of being stacked in a multi-stage manner so as to be able to be inserted and removed from a shelf rack.

And the seal member disposed in the fan accommodating section and the seal receiving member disposed in the lowermost panel accommodating section are adhered to each other.

That is, since the cooling fan is configured to be housed in the duct-shaped ventilation passage, the flow of air is prevented even between the housing portions of the cooling fan, and the cooling efficiency can be further improved.

[0015] In the seal structure between panels or the like according to the fifth aspect of the present invention, the seal member is formed of a tubular elastic body, and the seal receiving member is formed of a flat plate. .

In a state where the seal member and the seal receiving member are in close contact with each other, since the seal member is formed of a tubular elastic body, the seal member is appropriately flattened, and the area of close contact with the seal receiving member is increased. Thus, the space between the panel storage sections and the like can be reliably sealed.

According to a sixth aspect of the present invention, there is provided a seal structure between panels or the like for accommodating panels or the like, wherein the seal member is made of a rubber material, and at least a surface of the seal receiving member on which the seal member is rubbed is made of synthetic resin. It is characterized by comprising.

By forming the seal member from a rubber material, the seal member can be provided with appropriate elasticity. As a material for the seal member, rubber such as silicon or neoprene is preferable, but any rubber-based material that can maintain its own shape may be used. In addition, by forming the surface of the seal receiving member on which the seal member is rubbed with synthetic resin, the sliding between the seal member and the seal receiving member becomes good, and the shelf and the fan housing can be smoothly inserted and removed. . The material of the seal receiving member is preferably a fluororesin, but other synthetic resins may be used as long as they can slide the seal member. Further, the seal receiving member may be made of solid synthetic resin, or the main body may be made of metal, and the synthetic resin may be adhered to the surface on which the seal member rubs.

Further, the sealing structure between panels or the like according to the invention of claim 7 is characterized in that a fluid of an appropriate pressure is sealed in the sealing member.

Then, with the frame 18 accommodating the shelf 11 and the cooling fan 17 inserted into the shelf rack 10,
The seal member 20 and the seal receiving member 21 are configured to be in close contact with each other.

The operation of the embodiment of the sealing structure between the panels for accommodating the panels and the like according to the present invention constructed as described above will be described below.

When the frame 11 of the shelf 11 and the cooling fan 17 is inserted into the shelf rack 10, the seal member 20 and the seal receiving member 21 are brought into close contact with each other. 11a and first fan housing 15a
And the second panel housing 11b and the second fan housing 15b are shut off. That is, the first fan housing section
Duct-shaped air paths are formed by the first fan housing 15b and the second panel housing 11b, respectively, and by the second fan housing 15b and the second panel housing 11b. Then, when the cooling fan 17 arranged in the first fan housing portion 15a is operated, the air sucked from under the floor is discharged into the shelf rack 10, and the air is sucked from the first fan housing portion 15a to the first panel housing portion 11a. The air is blown, and the panels 12 stored in the first panel storage section 11a are cooled. The air provided for cooling is
After passing through the net 10a from the top of the shelf rack 10, the shelf rack 10
Is discharged to the outside. Similarly, when the cooling fan 17 arranged in the second fan accommodating portion 15b is operated, the panels 12 accommodated in the second panel accommodating portion 11b are cooled, and the air provided for cooling is supplied to the shelf rack 10 Exhausted from the top.

Since the flow resistance of the panels 12 accommodated in the first panel accommodating section 11a and the panel 12 accommodating the second panel accommodating section 11b are different from each other, cooling flowing through the inside of the panel accommodating sections 11a and 11b is performed. The air flow velocity is low for panels 12 with low flow resistance.
The second panel accommodating portion 11b accommodating the air becomes larger and tries to suck air from outside. But the first
Since the panel accommodating portion 11a and the first panel accommodating portion 15a are shut off, no air is sucked from these accommodating portions 11a and 15a. For this reason, the first panel storage section
The flow rate of the air flowing through the first fan accommodating portion 15a and the first fan accommodating portion 15a does not decrease, and the panels 12 are reliably cooled by being accommodated in the first panel accommodating portion 11a.

When performing maintenance or repair of the panels 12 and the cooling fan 17, the shelf 11 and the frame 18 are
Pull out from 10 and do. At this time, since the seal member 20 and the seal receiving member 21 can slide as appropriate, the shelf 11 and the frame 18 can be pulled out smoothly. When the maintenance or the like is completed, the shelf 11 or the frame 18 may be pushed in and housed in the shelf rack 10.

The embodiment described here is a preferred embodiment of the present invention, and the present invention is not limited to this, and can be variously modified and implemented without departing from the gist. Of course. For example, in the present embodiment, the seal member 20 and the seal receiving member 21 are shown as being wound around the peripheral ends of the panel accommodating portions 11a and 11b. This means that even if the structure is provided only at the upper and lower ends of the partition plate 13 in the shelf and at the upper end of the fan chamber partition plate 16, it is possible to shut off the space between the adjacent panel accommodating portions 11a and 11b. In addition, a sealing member 20 is provided at the upper end of the panel accommodating sections 11a and 11b and the fan accommodating section.
Although the structure has been described in which the seal receiving member 21 is attached to the lower end portions of the 11a and 11b, the seal receiving member 21 is provided at the upper end portions of the panel accommodating portions 11a and 11b and the fan accommodating portion, and the panel accommodating portions 11a and 11b are provided. A structure in which the seal members 20 are respectively attached to the lower ends may be used.

Although the seal member 20 has been described as a solid member having a circular or elliptical cross section, it may be formed in a tubular shape. If it is formed into a tube,
It is easier to provide greater elasticity than solid ones. In the case where the seal member is formed in a tubular shape, if the internal pressure thereof is smaller than the internal pressure of the panel accommodating portions 11a and 11b, the seal member is crushed and a gap is formed between the seal member and the seal receiving member. Then, there is a possibility that air may flow therefrom. For this reason, it is preferable that the internal pressure of the tubular seal member is set to be higher than the internal pressure of the panel storage portions 11a and 11b.

The seal receiving member 21 only needs to be able to slide on the surface in close contact with the seal portion 20. For this reason, the seal receiving member 21 may be configured such that the main body is formed of metal, and the close contact surface with the seal portion 20 is formed by attaching a synthetic resin plate or the like to the main body.
