SOLUTION: Air being fed into a radiator 2 by an up-blow fan ascends along a radiator panel 5 and flows into a vent because a collar 7 fixed to the vicinity thereof functions to produce an air pressure difference across the vent. Consequently, cooling power is enhanced at the upper part of the radiator panel 5. Since covers 8 are fixed to the opposite side face parts at the upper part of the radiator panel 5, air can be fed collectively to the vent even if the flow direction is deflected by the collar 7. Even if air flows through a gap 10, it can be fed collectively to the vent through action of the cover 8 and cooling power of the radiator 2 can be enhanced furthermore.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric device having a radiator having an upper blow fan attached to a lower portion thereof, and more particularly to an electric device in which a radiator panel constituting the radiator is improved.

[0002]

2. Description of the Related Art Hitherto, there has been known an electric device provided with a radiator for cooling the main body of the device. FIG. 13 shows a configuration of an electric device having a conventional radiator. A radiator 2 is provided on one side of the electric device 1.

Usually, a plurality of radiators 2 are arranged in parallel along the side surface of the electric device 1. Further, an upper blower fan 3 for blowing air upward is provided below the radiator 2. Note that reference numeral 9 in the figure indicates the main body of the electric device 1.

[0003]

In the electric apparatus 1 having the above-described structure, the flow rate of the air sent from the top blower fan 3 into the radiator 2 is higher than the flow rate 4a near the lower part of the radiator 2 above the radiator 2. In general, the flow velocity 4b in the vicinity is slower. However, the amount of heat radiation per unit area of the radiator panel 5 is larger near the upper portion of the radiator 2 than near the lower portion. Furthermore, the amount of heat radiation increases as the radiator panel 5 approaches the main body 9 of the electric device 1. Therefore, the radiator panel 5 tends to overheat at the upper part of the radiator 2, and the radiator panel 5 closer to the main body 9 of the electric device 1 has a further problem of overheating.

The present invention has been proposed to solve the above-mentioned problems, and an object of the present invention is to control a local overheating of a radiator panel by controlling a flow of air sent from a top blowing fan into a radiator. It is an object of the present invention to provide an electric device that can exhibit excellent cooling performance by preventing the occurrence of the cooling.

In order to achieve the above object, according to the first aspect of the present invention, a radiator having a plurality of radiator panels arranged in parallel is attached, and an air radiator is provided below the radiator in an upward direction. In an electric device in which a top blower for blowing air is installed, a vent is formed at an upper portion of the radiator panel, and collars for generating a pressure difference at both ends of the vent are attached near the vent, and A vertically extending cover is attached to both side surfaces of the upper part of the radiator panel.

According to the first aspect of the present invention, a ventilation hole is formed in the upper part of the radiator panel, and a collar attached near the ventilation hole generates a pressure difference between both ends of the ventilation hole. The air sent into the radiator can be sent to the vent. Therefore, a large amount of air can be supplied to the upper part of the radiator panel, which has a large amount of heat radiation per unit area, and the upper part of the radiator panel can exhibit excellent cooling ability. Moreover, since the covers are attached to both side portions of the upper part of the radiator panel, it is possible to prevent the air sent from the top blower from flowing out of the radiator panel. Therefore, it is possible to concentrate and send air to the ventilation port, that is, the upper part of the radiator panel.

According to a second aspect of the present invention, there is provided an electric apparatus, wherein a radiator having a plurality of radiator panels arranged in parallel is attached thereto, and an upper blower for blowing air upward is provided below the radiator. With the electric device main body side inside and the side away from the electric device as the outside, the radiator panel in the middle part excluding the innermost radiator panel and the outermost radiator panel rises as approaching the electric device main body side. And a horizontal collar extending horizontally from the radiator panel side where the ventilation port is formed toward the adjacent outer radiator panel is mounted above the ventilation port. It is characterized by having been done.

According to the second aspect of the present invention having the above-described structure, the air is fed from the top blower fan into the radiator by the function of the horizontal collar attached above the ventilation port located above the electric equipment body. Air 1
It flows sequentially from one vent to the adjacent vent. That is, the air flows in the radiator so as to rise in a stepwise manner toward the electric device main body. Therefore, it is possible to intensively send air to the vicinity of the upper part of the radiator panel on the side of the electric device main body which has a large amount of heat radiation, and the cooling capacity of this part is improved, thereby preventing local overheating of the radiator. In addition, by adjusting the width and length of the horizontal collar, the flow velocity and the direction of air flow can be easily controlled, so that a desired cooling capacity can be secured.

According to a third aspect of the present invention, in the electric device according to the second aspect, a cover extending vertically is attached below the horizontal collar and on both side surfaces of the radiator panel.

According to the third aspect of the present invention, the cover can prevent air from flowing out of the radiator panel. Therefore, it becomes possible to concentrate air near the upper part of the radiator panel on the side of the electric device main body which has a large amount of heat radiation, and the cooling capacity of that part is further improved.

According to a fourth aspect of the present invention, in the electric device according to the second or third aspect, the horizontal collar is attached across an adjacent radiator panel, and the horizontal collar on an outer radiator panel to which the horizontal collar is attached. A second ventilation hole is formed above the first ventilation hole.

[0012] In the fourth aspect of the present invention,
Since the second ventilation port is formed above the horizontal collar, air from the additional fan can be sent also above the radiator panel. In other words, according to the fourth aspect of the invention, it is possible to form two air steps rising in the radiator toward the electric device main body side. As a result, it is possible to increase the degree of air concentration near the upper part of the radiator panel on the side of the electric device main body which has a large amount of heat radiation, prevent local overheating of the radiator panel, and further improve the cooling capacity of the radiator.

According to a fifth aspect of the present invention, a radiator in which a plurality of radiator panels are arranged in parallel is mounted, and an upper blow fan for blowing air upward is installed below the radiator, and the plurality of radiators are arranged. In the electrical equipment, a wide-area collar is attached so as to straddle between the radiators, and the outer peripheral portion of the entire radiator has a vertical surface extending between the radiators and between the radiator panels on three surfaces excluding the electrical equipment main body side. Is attached to the cover.

In an electric device having a plurality of radiators, the air flowing between the radiators does not contribute much to the cooling, but in the invention of the fifth aspect having the above-mentioned structure, the air flowing between the radiators is arranged so as to extend between the radiators. Since the wide area collar is attached and the cover is attached to the outer periphery of the plurality of radiators, these members can take air between the radiators into the radiator. Therefore, local overheating of the radiator is prevented, and the cooling capacity of the radiator is improved.
