Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a heat exhaust device for removing heat generated from electronic equipment placed on a desk.

[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 devices 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.

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 require extensive construction work on the building, which would not be appropriate.

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. It is not possible.

In order to solve the above-mentioned problems, this invention aims to provide a heat exhaust device that can handle the exhaust heat even if the desk on which electronic equipment is placed can be freely arranged. do.

[Means for solving problems]

Next, means for achieving the above object will be explained with reference to FIGS. 1 and 2, which correspond to the first embodiment of the present invention.

That is, the present invention provides a heat exhaust device for electronic equipment 4 placed on a desk 1, which is fixed at a position below the top surface of the top plate 2 on the back of the desk 1 so as to be freely transportable together with the desk 1. A pipe-shaped heat exhaust duct section 5 is provided along the left-right direction of the desk 1, has a length substantially equal to the length of the desk 1 in the left-right direction, and has an upper surface of the top plate 2 of the desk substantially on the same plane. A heat exhaust port 7 communicating with the heat exhaust duct section 5 is formed at the position, and a heat exhaust port 7 is formed at the left and right ends so as to be freely connected to the connection openings at the left and right ends of the heat exhaust duct section of another adjacent desk. a heat exhaust duct portion 5 in which a connection opening 10 is formed; a hood device 11 having a shape that covers the upper part of the electronic equipment 4 and whose base portion is attached in communication with the heat exhaust port 7; It is characterized by comprising:

[Effect of idea]

As explained above, according to the heat exhaust device for electronic equipment according to the present invention, a heat exhaust duct section is provided on the back of the desk and has a length approximately equal to the left and right length of the desk so that it can be transported integrally with the desk. The connection openings on the left and right sides of the heat exhaust duct can be connected in a continuous manner with the connection openings of the heat exhaust duct of the desk installed adjacently. Since the heat generated by the electronic devices placed on each desk is exhausted through the device, the heat exhaust duct section of the heat exhaust device can be freely connected along the direction in which the office desks are arranged in the room. Heat generated from electronic devices on the desk can be dissipated,
The connection formation of the heat exhaust duct portion can be performed extremely easily and freely at the same time as the work of arranging each desk, and there is an excellent effect that the freedom of the layout and the workability of the arrangement work can be improved.

In addition, the heat exhaust port on the top surface of the heat exhaust duct is located on the same plane as the top surface of the desk, and the heat exhaust duct is fixed to the back of the desk at a position below the top surface of the desk. Unlike a structure in which the heat exhaust duct is formed at the top of the top plate, the worker's view is not obstructed, so there is no feeling of pressure, the top plate can be used widely, and the heat exhaust duct is not obstructed. The space for installing the device is small, and it is efficient as a heat exhaust device for the heat generated by small desktop electronic devices.
