Abstract

PURPOSE:To eliminate the need to provide a duct, an air suction fan, and a filter by cooling a screen through heat pipes and cooling fins fitted to parts of the heat pipes which project out from a display device main body. CONSTITUTION:One end of each of the heat pipes 8 fitted to the main body 1 through a support member 9 extends to nearby the screen 2, the other end projects out from the flank of the main body 1, and cooling fins 10 are fitted to the projection part. Then when working liquid absorbs heat from the screen 2 and moves to the other end of the heat pipe 8 projecting out from the main body 1, the other end and cooling fins 10 fitted to the other end exchange heat with the outside air, and the cooled working liquid moves to one end side of the heat pipe 8 again, absorbs heat from the screen 2, and moves. Consequently, the screen can be cooled even when none of the duct, fan, filter, etc., is provided.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to cooling of an image display device.

[Conventional technology]

3 and 4 are diagrams showing a conventional image display device disclosed in, for example, Japanese Utility Model Application Publication No. 60-96689. In the figures, (1) is the main body of the display device, and (2) is the front surface of this main body. Screen installed on the side, (3) is the outside air intake, (4)
is a filter, (5) is an intake duct whose one end communicates with the outside air intake (3), and whose a end is open to the back side of the screen (2), and (6) is installed inside this intake duct (5). The intake fan (7) is a louver.

Next, the operation will be explained. Since the screen (2) is a heating element, a fan (6) installed in the intake duct (5)
Clean air was taken in from the outside air intake (3) through the louver (7) and through the filter (4).

[Problem to be solved by the invention]

Conventional image display devices are installed at the bottom of the tank as described above, so there are issues such as the need to install a duct inside the main body, an intake fan, and a filter to prevent dripping and dust. there were.

This invention was made to solve the above-mentioned problems, and an object of the present invention is to obtain an image display device in which a duct and an intake fan can be eliminated, as well as a filter.

[T method to solve problems]

The image display device according to the present invention has a display device main body in a completely closed shape, eliminates the duct, fan and filter, and has one side 1 protruding inside the display device main body and the other side protruding outside the display device main body. A heat pipe is provided, and a cooling fan is attached to the part of the heat pipe that protrudes to the outside.

[For production]

In the image display device according to the present invention, the heat inside the display device body is released to the outside by the heat pipe and the cooling fan attached to the portion of the heat pipe that projects outside the display device body, thereby cooling the screen.

[Embodiment of the Invention] An embodiment of the invention will be described below with reference to the drawings. 1st
In Figures 2 and 2, (8) is attached to the main body (]) with a supporting member (

) protrudes outward from the side.

AO is a cooling fan tl-f attached to a portion protruding from the other end of the heat pipe.

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. One end of the heat pipe (8) extends to the vicinity of the screen (2) of the main body (1), so it absorbs the heat generated from the screen (2), and the working fluid protrudes outside the main body (1). pipe (8)
When it moves to the other end, the other end and the cooling fan aC+ attached to the other end exchange heat with the outside air and evaporate, and the cooled working fluid moves to one end of the heat pipe (8) again. It also absorbs heat from the screen (2) and moves.

〔Effect of the invention〕

As described above, according to the present invention, the display device main body is made into a completely closed shape, and a heat pipe is disposed with one side protruding inside the display device main body and the other side protruding outside the display device main body, and the heat pipe is displayed. Since the cooling fan is provided in the externally protruding portion of the main body of the device, the screen can be cooled even if the duct, fan, filter, etc. are eliminated.

Claims (1)

[Claims] A display device main body provided with a screen on the front surface, an air duct having one end communicating with an outside air intake provided in the display device main body and an outlet opening the other end opening on the back side of the screen, and an air duct inside the air duct. In the image display device equipped with an intake fan attached to the display device, the air duct and the fan are removed and the display device main body is made into a fully closed shape, so that one side protrudes into the display device main body and the other side protrudes outside the display device main body. A protruding heat pipe is installed in the
An image display device characterized in that a cooling fan is provided in a portion of the heat pipe that protrudes to the outside of the display device main body.
