Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a heat exhaust structure for electronic equipment that discharges heat generated from the electronic equipment.

[Conventional technology]

Traditional offices, especially tenant buildings, are often old buildings with very poor facilities, and many people are crammed into them, and even air conditioning, a basic condition of human life, has deteriorated. In addition, with the recent trend toward office automation, many types of office automation equipment have come into use. Electronic devices called office automation devices that are placed on a desk include computers, printers, desk fax machines, desk copiers, and the like. Examples of items placed on the floor include office computers, fax machines, photocopiers, and paper shredders.

By the way, it is said that the human body generates a calorific value of 100 Kcal/hour per person, but it is generally said that each electronic device generates a calorific value of 150 to 350 Kcal/hour.

Although a wide variety of electronic devices are used as mentioned above, the concentration of these devices and the increase in the number of devices are significant, and it is difficult to deal with the heat generated by them simply by introducing partitions or using existing indoor general air conditioning equipment. I'm starting to be unable to do that. In other words, it is wasteful to control locally generated heat throughout the room, and it also causes variations in room temperature, which is not efficient and has many problems in terms of comfort.

[Problem that the invention attempts to solve]

Nowadays, the work environment has become a hot topic of attention as a health issue, and new ideas have become necessary to solve air conditioning problems caused by the introduction of new heat sources such as electronic devices into offices. Furthermore, the number and layout of office electronic devices must be flexible. Furthermore, if the current type of office air conditioning were to be used to exhaust heat from all electronic devices in order to maximize exhaust heat efficiency, this would be inappropriate as it would require extensive construction work on the building.

As conventional heat exhaust devices for electronic devices, it has been proposed to install an air conditioning function in the partition or to install personal cooling equipment in desks, etc., but none of these are sufficient to solve the above problems. I can't.

In order to solve the above-mentioned problems, this invention aims to provide a heat exhaust structure that has a simple structure and can efficiently process exhaust heat in accordance with the layout and number of electronic devices.

[Means for solving problems]

The structure of the present invention will be explained with reference to FIGS. 1, 2, and 5.

As shown in FIG. 5, the heat exhaust structure 21 of this invention has a heat exhaust duct section 22 extending laterally along the upper part of the back of electronic equipment 72 placed indoors (on the top plate 91 in the embodiment). are installed in succession.

Looking at FIGS. 1 and 2, a heat exhaust port 29 is opened on the upper surface of the heat exhaust duct portion 22 along the longitudinal direction (lateral direction) through which air flows. A pair of closing members 30, 30 are provided along the heat exhaust port 29. That is, the base edge portions 30a, 30a of the closing members 30, 30 are fixed to the longitudinal wall portions of the corresponding heat exhaust duct portions 22, and the free end portions 30b, 3
0b are in contact with each other and have elasticity.

The pipe-shaped insertion part 23a at the base of the hood 23 is inserted into the heat exhaust port 29, and at this time, the supporting member 23b, which has a substantially U-shaped cross section and is fixed to the outer peripheral wall surface of the insertion part 23a, is connected to the heat exhaust duct part 22. It fits in contact with the top surface and front and rear walls. At this time, the hood 23 is
It covers the upper surface of the electronic equipment 72, and its inner surface communicates with the upper opening of the insertion portion 23a.

[Effect]

The heat generated from the electronic devices 72 is cooled by cold air released from inside the heat exhaust duct 22 to the insertion section 23a and the inner surface of the hood 23, or is transferred from the inner surface of the hood 23 to the insertion section 23a and the heat exhaust duct 2.
Heat is exhausted through 2.

When moving to the side of the electronic equipment 72, either pull out the insertion part 23a of the hood 23 and insert it into the heat exhaust port 29 at the corresponding position, or slide the inside of the heat exhaust port 29 to the corresponding position to remove the insertion. The portion 23a pushes out the closing members 30, 30 at the corresponding position, and the lower opening of the insertion portion 23a communicates with the inside of the heat exhaust duct portion 22, so that the cooling or heat exhausting action is performed at this corresponding position.
The other parts of the heat exhaust port 29 are closed by the free edges of the closing members 30, 30 coming into contact with each other.

At the insertion position of the insertion part 23a of the hood 23, the position is reliably determined from the point where the support member 23b is fitted onto the upper part of the heat exhaust duct part 22,
Since the hood 23 does not tilt forward, backward, left, or right, and the heat exhaust port 29 around the insertion portion 23a is hermetically covered by the support member 23b, the closing material 30 around the insertion portion 23a ,3
Even if the free edge of 0 is deformed and a gap is created, cold air or waste heat will not leak from the gap.

It can also be fixed to the rear side of the top plate 91 of 0.

Incidentally, the heat exhaust duct portion of any heat exhaust structure can be connected to an adjacent heat exhaust duct portion. Alternatively, cold air can be applied to electronic devices through the heat exhaust duct and the heat exhaust port to cool the electronic devices. Also, a large number of the devices of any of the embodiments can be connected in the horizontal direction.

[Effect of idea]

As explained above, according to the present invention, the heat exhaust port leading to the heat exhaust duct is formed in the longitudinal direction of air flow, and the free end portions of the heat exhaust port are closed with a highly elastic closing material. Because they are in contact with each other,
Although it has a simple structure, it can efficiently exhaust heat according to the number and layout of electronic devices. In other words, when electronic devices are placed, they cannot always be placed in the same position. For this reason, even if heat exhaust ports are provided at specific locations, heat cannot be efficiently exhausted. However, in the structure of this invention, openings of a certain size are provided virtually continuously in the longitudinal direction of air flow. Is possible.

Further, according to the present invention, the heat exhaust port 2 is provided at the base of the hood 23 which is shaped to cover the upper part of the electronic equipment 72.
A pipe-shaped insertion part 23a to be inserted into the heat exhaust port 29 is fixed downward, and a heat exhaust duct is provided on the outer peripheral wall surface of the intermediate part of the insertion part 23a at a position where the insertion part 23a is inserted into the heat exhaust port 29. Since the support member 23b, which has a generally U-shaped cross section with the opening facing downward, is fixed in contact with the upper surface and the front and rear walls of the portion 22, the support member 23b is fixed when the hood 23 is attached or removed.
b acts as a guide to facilitate the operation, and
During use, the hood 23 does not tilt forward, backward, left, or right, and the usage state of the hood 23 is stabilized.Furthermore, the heat exhaust port 29 around the pipe-shaped insertion portion 23a at the base of the hood 23 is sealed by the support member 23b. Even if the free ends of the closing members 30, 30 are deformed and a gap is created around the insertion portion 23a, cold air or exhaust heat will not leak from the gap, improving heat exhaust efficiency. It has the effect of
