Abstract

PURPOSE:To increase the load capacity of a heating component by providing first and second box bodies and arranging a heat pipe having one end projecting into the box body and the other end projecting to the outside thereby cooling the interior of the box body. CONSTITUTION:A first box body 6 containing a heating component 4 is provided and a second box body 7 communicated with the first body 6 is provided above the first box body 6. A heat pipe 9 having one end projecting into the box body 7 and the other end projecting to the outside is provided. When the air in the box body 6 is heated by the heating component 4 to increase its temperature, it is sucked upwardly through a suction type cooling fan 5 and subjected to heat-exchange with outer air through the heat pipe 9. Then the cooled air flows downwardly from the box body 7 into the box body 6 thus cooling the heating component 4. Consequently, the heating component is cooled continuously through circulation of air.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is applicable to, for example, the arrangement of a master disc of a large display device! This relates to a cooling device for a panel.

[Conventional technology]

The fourth factor in Figure 3 is the front view and measurement cross section of a conventional power distribution board, for example, a power supply panel used for a large display device. Door, (3I is a support plate provided inside the box body (fl), (4) is a heat-generating component such as a rectifier attached to this support plate, and (5) is a suction type that is also housed in the above support plate. This cooling fan is attached to the upper surface side of the heat generating component (4).

Next, the operation will be explained. The heat generating component (4) generates heat due to its load capacity. In order to cool down the generated heat, the generated heat (4) is cooled using a cooling fan/(5).
Forced cooling is performed by sucking up air from the direction of the

[Problem to be solved by the invention]

Since the conventional TA cooling system is configured as described above, the cooling fan only stirs the internal air, and it is necessary to cool the internal air inside the box, which results in the generation of Mm.
There were issues such as the product being unable to be cooled sufficiently and the load capacity of the heat-generating parts being unable to be increased.

This invention was made to solve the above-mentioned problems, and an object of the present invention is to obtain a cooling device for a power distribution board that can directly cool the inside air and increase the load capacity that heat-generating components can bear.

[Means to solve the problem]

The cooling device for a power distribution board according to J@Akira has a box body divided into a first box body and a second box body, and a first box body and a second box body. A heat pipe is disposed on at least one of the second boxes, the - side protruding inside the box, and the other side protruding outside the box.

[For production]

In the power distribution board cooling device according to the present invention, the inside air is directly cooled by the heat pipe, and the load capacity of the JA#1HB product is increased.

[Example M of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 5g
1. In Fig. 2, (6) is the first box body in which the heat generating parts (4) etc. are housed, and +7) is this first box body (6).
A second box body (8) is a lid attached to the first box body (6), and (9) is a lid attached to the first box body (6). The heat pipe is attached to the second box body, one part of which protrudes into the second box body, and the other side protrudes to the outside of the second box body.

Note that the old configuration is the same as the conventional one, so a description thereof will be omitted.

Next, the effect will be explained. When the air inside the first box body (6) is heated by the heat-generating parts (April) and the temperature rises, it is sucked into the upper mL by the suction type cooling fan (5), and the heat pipe (9) connects it to the outside air and heat. The cooling air of the second box body (7) that is cooled by the interaction flows into the lower blade and the first
The box (6) enters the circle and cools the heat generating parts (4). In this way, the air in the first box (6) and the second box (
7) The heat generating component (4) is constantly cooled by circulation with the circle.

In addition, in the above embodiment 1, the heat pipe is shown extending to the side of the second box body, but it may be made to protrude to the rear or top of the second box body.

In addition, in the actual N meat above, the second box body was provided above the first box body, but if the suction type cooling unit is located above the heat generating component, it may be equipped with a heat pipe. The second box body may be located below the first box body, and the same effect as the actual M91 described above can be achieved.

〔Effect of the invention〕

As described above, according to the present invention, the box body is divided into the first box body and the second box body, and at least one side of the first box body or the second box body protrudes into the inside of the box body, Since the heat pipe is arranged so that the other side protrudes outside the box, the air inside the box is cooled, which has the effect of sufficiently cooling the heat-generating components and increasing the load capacity that the heat-generating components can handle. .
