[Problems to be solved by the device]

 However, the cooling device for the electronic device casing shown in FIGS. 5 and 6 still has the following problems to be improved. Usually, in a factory or the like, many electronic device housings 1 are installed in a small room. A passage is provided in front of the front surface 3a of the electronic device casing 1 so that the surveillance staff can monitor each electronic device while patrolling it. The rear surfaces 3b are arranged so as to face each other with a short gap.

As a result, as shown in FIG. 6, the exhaust windows 4 on the back surface 3b of each electronic device housing 1 face each other with a narrow gap therebetween. Therefore, the hot air 7 discharged from the exhaust windows 4 on the opposite side collide with each other, and the hot air 7 is not efficiently discharged to the outside.

Therefore, the cooling efficiency is reduced. In order to solve such a problem, it is necessary to change the exhaust fan 5 to a high output unnecessarily or rearrange it so that the gap between the back surfaces 3b of the electronic device housings 1 is widened. is there.

However, if the output of the exhaust fan 5 is increased, not only the manufacturing cost of the entire electronic device housing 1 is increased, but also the output of the exhaust fan 5 is increased on the other side. There is a concern that they will be offset.

Further, if the gap between the electronic device housings 1 is set to be wide, there arises a problem that a required area of a room in which a large number of electronic device housings 1 need to be installed is increased. The present invention has been made in view of such circumstances, and even if the electronic device housings are connected to each other by forming a skylight on the upper wall and attaching a swivel duct that can be rotated upward to the skylight. Even if the space is narrowed, it is possible to prevent the exhausted hot air from colliding with each other, and even if an exhaust fan with a small output is used, a sufficient cooling effect can be obtained and the inside of the electronic device housing can be obtained. (EN) Provided is a cooling device for an electronic equipment casing, which can improve the reliability of each stored electronic equipment, reduce the manufacturing cost, and reduce the installation area when a large number of electronic equipment casings are installed. With the goal.

[Action]

 In the cooling device for an electronic device casing configured as described above, a rotating duct that can be rotated upward is attached to one edge of the skylight, and an exhaust fan is attached to a free end of the rotating duct. . Further, a vertical window is formed on the vertical wall adjacent to the skylight. Then, if the exhaust fan is driven in a state where the rotating duct is rotated upward, the hot air inside the electronic device housing is exhausted above the electronic device housing.

Further, when the exhaust fan is driven with the shutter opened and the rotating duct is rotated downward to the position where the skylight is closed, the hot air inside the electronic device casing is reflected on the vertical wall of the electronic device casing. Air is exhausted horizontally from the punched vertical window with respect to the electronic device housing.

Therefore, when the two electronic device casings are arranged back to back or adjacent to each other, the rotation duct of one electronic device casing is rotated upward and the other electronic device casing is rotated. By setting the moving duct horizontally, that is, by closing the skylight and driving the exhaust fans, it is possible to prevent the hot air exhausted from directly colliding with each other. Therefore, the cooling efficiency in each electronic device housing can be improved.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 2A and 2B are external views of the electronic device housing of the embodiment, and FIGS. 1A and 1B are cross-sectional views of the electronic device housing shown in FIG. is there.

A plurality of chassis 12 are arranged in the electronic device housing 10 formed in a substantially rectangular parallelepiped shape so as to be spaced from each other at a constant interval and to project in the front direction of the front surface 13 a of the electronic device housing 10. It is stored.

A rectangular skylight 15 is formed at a position adjacent to a rear wall 13b as a vertical wall of the upper wall 14 of the electronic device housing 1. Further, one end of a rotating duct 16 is attached to one edge on the front surface side of the skylight 15 so as to be rotatable upward. The upper plate 16a of the rotating duct 16 has substantially the same shape as the skylight 15, and the pair of side plates 16b on both sides have a substantially right triangle shape. Then, three exhaust fans 18 are attached to the free end side of the rotating duct 16.

A rectangular vertical window 19 is formed at the upper end position of the rear wall 13b of the electronic device casing 10. The vertical window 19 can be closed by a shutter 20 which is slidably attached to the inner surface of the rear wall 13b.

As shown in FIG. 1B, when the rotating duct 16 is rotated upward with respect to the upper wall 14, the exhaust fan 18 faces diagonally upward. Further, as shown in FIG. 1 (a), when the upper plate 16a is rotated downward to a position where the skylight 15 is closed, the exhaust fan 18 is moved to the vertical window 19 formed on the rear wall 13b. opposite.

In the cooling device for the electronic device housing 10 configured as described above, when the exhaust fan 18 is driven in the state shown in FIG. 1A, the outside air 21 flows from the gap between the chassis 12 into the electronic device housing. It flows into 10. Then, the outside air 21 that has flowed in absorbs the heat generated by the electronic devices housed in the chassis 12 in the process of flowing through the gap between the chassis 12 and the inside of the chassis 12, and becomes the hot air 22 to form the rotating duct 16. Through the exhaust fan 18, the air is exhausted in the horizontal direction from the vertical window 18 provided on the rear wall 13b.

Further, when the exhaust fan 18 is driven in a state where the rotary duct 16 shown in FIG. 1B is rotated upward, the hot air 22 inside the electronic device casing 10 is discharged through the rotary duct 16. The air fan 18 exhausts the gas obliquely upward.

A method of setting each rotating duct 16 and each shutter 20 when a plurality of electronic device casings 10 having such a configuration are installed adjacent to each other will be described with reference to FIGS. 3 and 4. FIG. 3 is an external view showing a state in which a plurality of electronic device casings 10 are arranged back to back with each other, and FIG. 4 is a sectional view of each electronic device casing 10 taken along an alternate long and short dash line and seen from the direction of arrow A. FIG.

As described above, when a plurality of electronic device casings 10 are arranged back to back, the rotating duct 16 of one electronic device casing 10 is rotated upward and the shutter is released. The vertical window 19 is closed at 20. Then, the turning duct 16 of the other electronic device housing 10 is turned downward to close the skylight 15 by the upper plate 16a, and the shutter 20 is lowered to open the vertical window 19.

When each exhaust fan 18 of each electronic device housing 10 is driven in such a state, the hot air 22 inside one electronic device housing 10 is exhausted obliquely upward, and inside the other electronic device housing 10 The hot air 22 is exhausted horizontally from the vertical window 19. Therefore, the hot air 22 exhausted from both electronic device housings 10 is prevented from colliding with each other.

Further, since the vertical window 19 of the electronic device casing 10 on the side where the rotating duct 16 is rotated upward is closed by the shutter 20, the vertical window 19 of the adjacent electronic device casing 10 is removed. The exhausted hot air 22 does not flow into the electronic device housing 10 of its own.

As described above, even if the electronic device housings 10 are arranged with a minute gap therebetween, the cooling efficiency of each electronic device housing 10 does not decrease. Therefore, it is not necessary to increase the output of the exhaust fan or arrange the electronic device casings 10 sufficiently apart from each other, unlike the conventional electronic device casings.

The present invention is not limited to the above embodiment. In the embodiment, the turning direction of the turning duct 16 is directed toward the back wall 13b, but it may be turned to the left and right sides when viewed from the front surface 13a, for example. In this case, it is necessary to install vertical windows on each side wall.

[0026]

[Effect of device]

 As described above, according to the present invention, the skylight is formed on the upper wall, and the swivel duct which is rotatable upward is attached to the skylight. Therefore, even if the electronic device housings are arranged with a narrow gap between them, it is possible to prevent the hot air exhausted from colliding with each other, and it is sufficient even if an exhaust fan with a small output is used. The cooling effect can be obtained, the reliability of each electronic device housed in the electronic device housing can be improved, the manufacturing cost can be reduced, and the installation area for installing a large number of electronic device housings can be reduced.
