Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sealed cubicle device with a built-in electronic device.

[0002]

[Prior art]

 Conventionally, there is a closed cubicle device, and its outline will be described below with reference to FIG.

That is, 11 is a peripheral wall of a closed cubicle, 12a is an electronic device arranged in the lower part of the cubicle, 12b is an electronic device arranged in the upper part of the cubicle, and 12c and 12c are electronic devices 12a, 12b. It is a mount that supports.

Reference numeral 13 denotes a heat exchanger for releasing the heat generated from the electronic device to the outside air, which is a heat pipe 13a for moving the heat, and the heat transfer for the inside air which is in close contact with the heat pipe 13a. The fins 13b and the heat transfer fins 13c for outside air are included.

Reference numeral 14a is an inside air fan for circulating the inside air of the cubicle, and 14b is an outside air fan for flowing the outside air.

[0006] Next, the operation of this device will be described. In the electronic devices 12a and 12b, the allowable upper limit temperature is determined by the material of which the electronic devices 12a and 12b are made, and the electronic devices 12a and 12b are kept so as not to exceed this temperature. It is necessary to release the heat generated by to the outside air.

For this reason, the inside air fan 14a is rotated to cause the inside air of the cubicle to flow in the direction of the arrow f1, whereby the inside air also circulates inside the cubicle with a convection effect, and in this process, the lower electronic device is first. At the same time as cooling 12a, it itself is heated by the heat generated by this electronic device 12a and its temperature rises.

Subsequently, the inside air reaches the upper electronic device 12b and cools it, and the temperature of the inside itself further rises. Then, the inside air reaches the heat exchanger 13, where it contacts the inside air fin 13b. After the heat is removed, it is circulated again as described above.

On the other hand, the heat taken by the inside air fin 13b reaches the outside air fin 13c through the heat pipe 13a and is then carried away by the outside air flowing in the outside air fan 14b.

[0010]

[Problems to be solved by the device]

 In the above-described closed cubicle device, the inside air cooled by the heat exchanger 13 first acts to cool the lower electronic device 12a and then to cool the upper electronic device 12b. The difference between the temperature of the device 12b and the temperature of the inside air for cooling the device 12b is smaller than that in the case of the lower electronic device 12a, and therefore the temperature of the upper electronic device 12b is lower. 12a is higher than that of the electronic device 12a, the performance of the electronic devices 12a and 12b as a whole may be impaired, and the life of the electronic device 12b on the upper side may be shortened. An object of the present invention is to provide a closed-type cubicle device which can solve such problems.

[0011]

[Means for Solving the Problems]

 The present invention cools the upper electronic device located in the upper part of the cubicle and the lower electronic device located in the lower part of the cubicle, so that the inside air of the cubicle is circulated by a fan and heat exchange is performed in the middle of the circulation path. This is a closed cubic device that is cooled by an air conditioner, and is equipped with a duct for guiding the air cooled by the heat exchanger, and the air outlets of this duct are connected to the upper electronic device and the lower electronic device. It is characterized by being located in the vicinity of each of.

At this time, it is preferable that the air outlet is opened on the lower surface side of each of the upper electronic device and the lower electronic device so that air is blown upward from the air outlet.

Further, the structure can be simplified by replacing a part of the side surface of the cubicle with a heat exchanger.

[0014]

[Action]

 The duct is to blow the inside air cooled by the heat exchanger from the air outlet to the upper electronic device and the lower electronic device separately, so that each electronic device is exposed to the air of the same temperature, It will be cooled to the same temperature.

The air blown upward from the air outlets opened on the lower surface side of each electronic device smoothly flows upward through the gaps of each electronic device to cool each electronic device to a uniform temperature. Contribute above.

【Example】

 FIG. 2 is a sectional view of a closed type cubicle showing an embodiment of the present invention.

In the drawing, 21 is a peripheral wall of a closed cubicle, 22a is an electronic device arranged in the lower part of the cubicle, 22b is an electronic device arranged in the upper part of the cubicle, 22c and 22c are both electronic devices 22a, The mount 22b is supported, and p and p are through holes provided in the mount 22c.

Reference numeral 23 denotes a heat exchanger for discharging the heat generated by the electronic devices 22a and 22b to the outside air, and is a passage 23a for the inside air for circulating the inside air of the cubicle, and is orthogonal to the passage 23a for the inside air. The external air passage 23b is arranged as described above and through which the external air flows.

Reference numeral 24a is an inside air fan for circulating the inside air, and 24b is an outside air fan for flowing the outside air.

Reference numeral 25a denotes a duct for supplying the inside air emitted from the heat exchanger 23 to the electronic device 22a on the lower side, and 25b for supplying the inside air emitted from the heat exchanger 23 to the electronic device 22b on the upper side. Air ducts m, m of the ducts 25a, 25b are opened on the lower surface side of the electronic devices 22a, 22b.

The operation of this embodiment configured as described above will be described. The inside air cooled by the heat exchanger 23 is diverted to the duct 25a and the duct 25b by being flown to the inside air fan 24a, and then a uniform temperature state is obtained from the lower surface side of the electronic devices 22a and 22b. Is blown upwards at.

Subsequently, the inside air reaches the respective electronic devices 22a and 22b through the vertical passages (not shown) of the pedestals 22c and 22c, and the heat of the electronic devices 22a and 22b is absorbed therein to rise in temperature.

At this time, since each of the electronic devices 22a and 22b is exposed to the inside air of a uniform temperature, both are cooled to substantially the same temperature.

After that, the inside air flows in the direction of arrow f2 and reaches the heat exchanger 23, where it is cooled by coming into contact with the wall surface w that separates the inside air passage 23a and the outside air passage 23b, and the duct again. It is made to flow toward 25a and 25b.

On the other hand, the heat transferred to the wall surface w is carried away by the outside air flowing by the outside air fan 24b.

In the above embodiment, a part of the side surface of the cubicle peripheral wall 21 is replaced with the heat exchanger 23, but instead of this, the heat exchanger 23 is placed inward or outward of the cubicle. It can also be provided independently.

[0027]

According to the present invention configured as described above, the upper and lower electronic devices in the cubicle can be cooled to substantially the same temperature, which can maintain good performance of the entire electronic device. The life of the electronic device can be extended.
