[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic device apparatus typically typified by a small-sized information processing device such as a laptop computer or a personal word processor, and particularly to an electronic device apparatus having improved cooling characteristics.

[0002]

[Prior art]

 This type of electronic equipment device is configured by housing electronic components such as a board or a disk device or a fan in a housing. The heat generation amount of these electronic components, which are generally heat generation sources, tends to increase with high-density mounting. Since electronic components are required to have an operating environment that does not exceed the specified temperature conditions, it is necessary to implement the above-mentioned high-density mounting from the viewpoints of ensuring the reliability of the device and ensuring the specified performance. It is necessary to take effective measures against high heat generation.

Generally, not only small electronic devices such as laptop computers and personal word processors, but also electronic devices having various electronic components and device units housed in a housing, forced air cooling or A mechanism is provided to realize natural air cooling.

FIG. 7 and FIG. 8 show a housing structure in an electronic device having a mechanism for forced air cooling, and a ventilation part 16 is provided in various parts of the housing 1. The ventilation part 16 has a plurality of ventilation holes that are hollowed out in a rectangular shape and are arranged in a line to form a substantially slit shape. In the vicinity of the housing 1 provided with the ventilation part 16, electronic parts (not shown) such as a CPU that generates relatively high heat and fans (not shown) for intake and exhaust are provided.

According to the conventional electronic device having such a configuration, the heat generated from the electronic components is taken away by the cooling air 30 generated by the rotation of the fan, and the cooling air 30 is transferred to the outside of the housing 1. Is discharged.

[0006]

[Problems to be solved by the device]

 However, since the ventilation part 16 is simply configured by arranging a plurality of ventilation holes that are hollowed out in a rectangular shape in a linear manner, the ventilation resistance is large, and the air flow 30 smoothly moves into and out of the housing 1. The air may not be ventilated, and the recirculation air 30b may be generated in the vicinity of the ventilation part 16 to recirculate inside the housing 1. As a result, the cooling performance is deteriorated, and the reliability of the device is impaired.

Therefore, an object of the present invention is to provide an electronic device apparatus in which an air flow is smoothly ventilated to the inside and the outside of a housing, thereby preventing a decrease in cooling performance.

[0008]

[Means for Solving the Problems]

 The present invention is configured as follows in order to solve the above problems and achieve the object. That is, according to the present invention, an electronic component is housed in the housing part of a housing having a housing part inside and forming a ventilation part for allowing air to flow between the housing part and the outside. According to another aspect of the present invention, there is provided an electronic device apparatus, wherein the ventilation part of the housing is provided with a rectifying mechanism for rectifying the flow of the air.

[0009]

[Action]

 According to the present invention having the above-described configuration, since the ventilation part is provided with the rectifying mechanism for rectifying the air flow, the air flow is smoothly ventilated to the inside and the outside of the housing. Therefore, it is possible to effectively prevent the deterioration of the cooling performance.

【Example】

 Hereinafter, a first embodiment of an electronic device according to the present invention will be described with reference to FIGS. As shown in FIG. 1, a ventilation portion 11 is provided at a specific portion of the housing 10, for example, a side surface portion and a back surface portion. In general, the ventilation part 11 is provided near a unit 12 provided with a fan 12 for intake / exhaust and an electronic component 13 such as a CPU that generates relatively high heat, and also at a position suitable as an air intake port. To be

As shown in FIGS. 2 and 3, the ventilation part 11 has a large number of ventilation holes 16 which are hollowed out in a rectangular shape as shown in FIG. A plurality of slits 15 are arranged side by side along the above, and ribs 17 are formed on both sides of the vent hole 16 in the plurality of slits 15. The ribs 17 extend in the height direction of the housing 10 and are arranged side by side in the housing 10 so as to extend in the horizontal direction. According to the electronic device apparatus of the present embodiment configured as described above, since the ventilation part 11 has the configuration in which the convex ribs 17 are formed on both sides of the ventilation port 16, the air flow 30 is vented. The airflow 30a passing through the mouth 16 is rectified by the ribs 17. This reduces the air flow resistance. Therefore, the conventional reflux is prevented, the cooling performance is not deteriorated, and the reliability of the device is secured.

Further, since the deterioration of the cooling performance is prevented, it is not necessary to attach a fan having a large airflow and a large static pressure. This means that various measures such as changing the mounting structure that are necessary when installing a fan with a large air flow and static pressure are not required, and it is possible to prevent cost increases before they occur. It also eliminates the need for expansion of the mounting space required by.

Further, since the air flow 30a when the air flow 30 passes through the vent 16 is rectified by the ribs 17 and the resistance of the air flow becomes small, the wind noise generated at the vent 16 is reduced. It is small and does not give the operator any discomfort.

In the above-described embodiment, the rib 17 is used as a mechanism for rectifying the air flow 30a when the air flow 30 passes through the ventilation port 16. However, in addition to this, another rib of the present invention is used. As an example, as shown in FIG. 4, a taper 18 may be formed on each side of the vent hole 16 in the plurality of slits 15.

Even with such a configuration, as in the above-described embodiment, it is possible to prevent the cooling performance from deteriorating, and to eliminate the need for various measures such as changing the mounting structure, and to eliminate wind noise. It can be reduced.

Next, still another embodiment of the present invention will be described with reference to FIGS. 5 and 6. As shown in FIG. 5, in this embodiment, the rib 17, taper 18 or rib 17 and taper 18 are provided at a specific portion of the housing 20 depending on the necessity of rectification. As shown in the figure, for example, as shown in FIG. 6, a ventilation part 11 provided with a rib 17 and a taper 18 is provided on the back face portion and the side face portion connected to the back face portion shown in FIG. On the side surface portion connected to the front surface shown in X in the drawing, for example, an air passage portion 11 provided with a rib 17 shown in FIG. 2 is provided.

With such a configuration, the rectification is performed in the right place in the right material, and the same effect as that of the above-described embodiment becomes more practical. The rib 17 and the taper 18 should be formed on at least the inner wall of the housing, but may be formed on the inner and outer walls. The present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.

[Effect of device]

 As described above, in the present invention, since the ventilation part is provided with the rectifying mechanism for rectifying the air flow, the air flow can be smoothly ventilated to the inside and the outside of the housing. Therefore, according to the present invention, it is possible to provide an electronic device device capable of preventing a decrease in cooling performance.
