Abstract

PURPOSE:To obtain a display device in which heat exchange between the inside and the outside of a housing can be performed even when the housing is tightly sealed and which has a dustproof and rainproof effect by disposing a heat pipe whose one side extends near the display part in the housing and whose other side protrudes outside the housing. CONSTITUTION:When heat is evolved from the display part 2 in the housing 1, the temperature in the housing 1 rises. Since the heat pipe 8 whose one side protrudes inside the housing 1 and whose other side protrudes outside the housing 1 is attached, the heat exchange between the inside and the outside of the housing 1 is performed through the heat pipe. Then, the inside of the housing is cooled and the display part is cooled.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device having a display section formed by arranging a large number of electron tubes in a matrix.

[Conventional technology]

3 and 4 are diagrams showing a conventional display device disclosed in, for example, Japanese Patent Application Laid-Open No. 59-204084. The display section (2
) on the front surface (3), and a desired image is displayed on the display section (2) by selectively operating the electron tubes.

Next, the operation will be explained. The display section (2) usually uses tens of thousands of electric light tubes, and the amount of heat generated here is considerable. Therefore, a fan unit (5) is provided along the back surface (4) of the box (1) of the large-sized display device in order to cool the display section (2). This fan unit (5) usually consists of a plurality of fans (6
), which takes in outside air through the outside air inlet (7) installed on the back (4) of the large display device (11)
Cool 2 tons.

[Problem to be solved by the invention]

Since the conventional display device is configured as described above, it requires a large number of cooling fans, and also has the problem that it cannot be dust-proof or rain-proof because it sucks in outside air.

This invention has been made to solve the above-mentioned problems, and aims to provide a display device that can eliminate the need for a cooling fan and is also dust- and rain-proof.

[Means to solve the problem]

The display device according to the present invention includes a heat pipe whose one side extends to the vicinity of the display section inside the box through at least one of the back, side, top, and bottom surfaces of the box and whose other side protrudes outside the box. This is what was installed.

[For production]

In the display device according to the present invention, the inside of the box is cooled by the heat pipe to cool the display section.

[Embodiments of the invention]

Hereinafter, one embodiment of this invention will be explained with reference to the drawings.

? In FIG. 41 and FIG. 2, (8) is a heat pipe attached via the back part (4) of the box body (1),
The - side extends to the vicinity of the display section (2) inside the box (1), and the other side protrudes to the outside of the box (1).

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. When the display section (2) inside the box (1) generates heat, the filter inside the box (13) rises.
Inside the box (1), one side is attached to the box (a heat pipe (8) with the other side protruding is attached to the outside of the box 11, so the heat pipe connects the inside of the box (1) and the box Q). is subjected to heat exchange with the outside.

C. Effects of the Invention] As described above, according to the present invention, the - side extends to the vicinity of the display part inside the box body through at least one of the side faces, top surface, and bottom surface of the box body, and the other side extends to the vicinity of the display part of the box body. Since the heat pipe is arranged so as to protrude to the outside, there is an effect that heat exchange can occur between the inside and outside of the box even if the box is sealed.

[Brief explanation of drawings]

1-1 and 2 are views showing a display device according to one aspect of the present invention, in which FIG. 1 is a plan view, FIG. 2 is a perspective view seen from the rear of FIG. 1, and i! 3 and 4 are diagrams showing a conventional display device, where FIG. 3 is a plan view and FIG. 4 is a perspective view as seen from the rear direction in FIG. 3. In the figure, (1) is the box of the display device, (2) is the display section, (3) is the front surface, (4) is the back surface, and (8) is the heat pipe. In addition, in the figures, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Claims] In a display device having a display part housed in a box and having a large number of electron tubes arranged in a matrix on the front surface of the shaft, at least one of the back, side, top and bottom surfaces of the box is A display device characterized in that a heat pipe is provided, one side of which extends to the vicinity of a display portion within the box body, and the other side of which protrudes outside the box body.
