Abstract

PROBLEM TO BE SOLVED: To provide a PDP display device which can lower the temperature of the hot air discharged outside a PDP display device body by a cooling fan. SOLUTION: The PDP display device, which is provided with a cooling fan for discharging the high-temperature air in the PDP display device body outside within the PDP display device body is provided with a duct section for discharging the high-temperature air in the PDP display device body sucked by the cooling fan outside the PDP display device body. Outdoor air inhalation holes are formed on the flanks of the duct section.

2. Description of the Related Art Plasma display panels (hereinafter referred to as P
In a PDP display device equipped with a plasma display panel (DP), unlike a normal television receiver, a PD
Heat dissipation measures for the P panel and PDP drive power supply have become important issues.

In order to cope with this problem, as shown in FIG. 4, in a conventional PDP display device 10, a P
A plurality of cooling fans 11 for cooling radiant heat generated by the DP panel and the PDP drive power supply are provided. By these cooling fans 11, high-temperature air inside the housing is sucked and discharged outside the housing, and low-temperature outside air is sent into the housing.

[0004] As shown in FIG. 4, when a television program is viewed for a long time with the PDP display device 10 attached to the wall 200, the cooling fan 11 generates high-temperature hot air outside the housing. It will continue to be discharged. As a result, there has been a problem that the wallpaper formed on the wall surface is peeled off.

SUMMARY OF THE INVENTION An object of the present invention is to provide a PDP display device capable of lowering the temperature of hot air discharged from the PDP display device body by a cooling fan.

[0006]

According to the present invention, there is provided a PDP display device in which a cooling fan for discharging high-temperature air in the PDP display device main body to the outside is provided in the PDP display device main body. , A duct portion for discharging high-temperature air in the PDP display device main body sucked by the cooling fan to the outside of the PDP display device main body is provided, and an outside air suction hole is formed on a side surface of the duct portion. It is characterized by.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIGS. 1 and 2 show a PDP display device.

This PDP display device 100 is a conventional PDP display device.
A duct unit 20 for lowering the temperature of hot air discharged to the outside is attached to the upper surface of the P display device 10.

The duct unit 20 has a horizontal L-shaped cross section, and has a triangular left and right side wall 21 and a horizontally long rectangular front wall 2.
2 and a horizontally long rectangular lattice-like top plate 23. The duct unit 20 includes the PD sucked by the cooling fan 11.
A duct for discharging the high-temperature air inside the P display device body to the outside is formed, and the left and right side walls 21 and the front wall 2 are formed.
2 constitutes the side surface of the duct portion.

The left and right side walls 21 are provided with outside air intake holes 21a for taking in outside air. Also, front wall 2
2, a plurality of outside air intake holes 22a for taking in outside air are provided.

As shown in FIG. 2, high-temperature air (hot air) sucked from the inside of the PDP display device 100 by the cooling fan 11 passes through the duct unit 20 to the outside through the air circulation holes of the grid-like top plate 23. Released.

At this time, since the outside low-temperature air is sucked into the duct unit 20 from the outside air suction holes 21a and 22a (the outside air suction holes 21a and 22a formed on the side surface of the duct portion) of the duct unit 20, the PDP Display device 10
0 Duct unit 20 from inside by cooling fan 11
The high-temperature air sent into the inside is supplied to the outside air intake holes 21a, 2a.
It is cooled by the external low-temperature air sucked from 2a. Therefore, the temperature of the hot air discharged from the duct unit 20 to the outside is reduced as compared with the related art.

As shown in FIG. 3, when the front surface of the PDP display device 100 is on the opposite side of the front and rear sides of FIG. 2, the PDP display device 100 is used to allow outside air to be taken in from the outside air intake hole 22a. What is necessary is just to attach 100 to a wall via a spacer.

[0015]

According to the present invention, the temperature of the hot air discharged from the PDP display device by the cooling fan can be reduced.
