Abstract

PURPOSE:To eliminate the necessity of an air conditioner and reduce the weight of a display by providing the inside of an air introducing duct with heat pipes with one side projected inside the air introducing duct and the other side projected outside a casing body. CONSTITUTION:Heat pipes 8 with one side projected inside an air introducing duct 5 in a casing body 1 and the other side projected outside the casing body 1 are provided. The warm air flowing into the air introducing duct 5 from an air collecting duct 4 is cooled by the heat pipes 8 with one side projected inside the air introducing duct 5 and with the other side projected outside the casing body 1. The air which has become heavy by being cooled circulates in the air introducing duct 5 via a falling cool air blowoff opening 61, a cool air inlet 71 and a cool air outlet 72. The warm air which has been lightened after cooling a light emitting display 2 rises upward and is introduced again to the air introducing duct 5. Thus, the necessity of an air conditioner in the display in eliminated and the weight of the display can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device for displaying characters, images, etc.

[Conventional technology]

Figure 2 is a cross-sectional side view showing a conventional display device shown in, for example, Japanese Utility Model Application Publication No. 57-065380. The light-emitting display section (3) is placed on the front, and the separator (1) is placed behind the light-emitting display section (2). The air collection duct (5) collects the warm air in the air collection duct (4) and sends it to the air conditioner (
6), (7) is a cold air inlet (71) facing the cold air outlet (61) of the air machine (6), and a cold air outlet D (facing the lower part of the light emitting display section (2)). 72) is the floor of the box body (1).

Next, the operation will be explained. The back of the light-emitting display 5 (2) is completely sealed by the old pallet (3rd part), so
As shown by the solid line arrow, the light emitting display part (22) is blown out from the cold air outlet (62) below.
2) is cooled, and the warm air is drawn out from above and collected in the air collection duct (4), passes through the air intake duct (5), and is sent to the air conditioner (
6). This warm air is cooled by the air conditioner (6), blown out under the floor from the air outlet (61) and cold air inlet (71) of the air conditioner (6), and guided to the light emitting display section (2) through the cold air outlet (72). He will be circulated again by the same route.

[Problem to be solved by the invention]

Since the conventional display device is configured as described above, it is necessary to install 11 air conditioners, a power source for the air conditioner is also required, and since the air mis is P3M inside the box, the amount of one display device is Like becoming heavier: a! 8 is there:.

This invention was made to solve the above-mentioned problem, and aims to provide a display device that does not require an air conditioner and can also reduce the weight of the display device.

[Means to solve the problem]

The display device according to the present invention is provided with a heat pipe whose one side protrudes into the air conduction tact and the other side protrudes to the outside of the box.

[For production]

In the display device according to the present invention, heat is exchanged between the air inside and outside the box body using the heat pipe, and the light emitting display section is cooled.

[Embodiment of the Invention] An embodiment of the invention will be described below with reference to the drawings. 1st
In the figure, (8) has a minus side protruding into the air conduction duct (5) inside the box (1), and the other side protruding outside the box (1). 1: Heat pipe.

4. Note that the other configurations are the same as those of the prior art, so explanations will be omitted.

Next, the operation will be explained. The warm air flowing from the air collection duct (4) to the air guide duct (511ζ) is transferred to the 4 air tact (5)
One side of the circle protrudes and the other side protrudes to the outside of the box body (1), which is cooled by the heat pipe and becomes heavier as it cools.
This air flows down inside the air guide tact (5) and cool air outlet (
61) to the cold air inlet (71), and then the cold air outlet (7
2) And? ii) The light-emitting display section (2) is cooled and lightened, and the warm air rises and is led to the air-conducting tact (5).

〔Effect of the invention〕

As described above, according to the present invention, a heat pipe is provided with one side protruding into the air conduction tact and the other side protruding outside the box body, thereby eliminating the need for an air conditioner inside the display device. This has the effect of reducing the weight of the display device.

[Brief explanation of drawings]

FIG. 1 is a cross-sectional side view of a display device according to an embodiment of the present invention, side view (2). In the figure, is the air intake duct, and is Eve. In addition, in the figure, is shown. 2) Cross section of a conventional display device (1) is the box, (2) is the light emitting display, (5) is the air conduction duct, (8) is the heat bar. Same symbols are the same or 1 are corresponding parts.

Claims (1)

[Claims] A light-emitting display section that is arranged on the front side of the inside of the box body and displays characters, images, etc.; an air collection duct and an air guide duct that are provided on the back side of the light-emitting display section that circulate the air inside the box body; A display device including a heat pipe with one side protruding into the air conduction duct and the other side protruding outside the box.
