Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a sirocco fan used for cooling a PDP monitor or the like, and more particularly to a PDP cooling sirocco fan capable of changing a direction of discharging hot air in accordance with an installation method of the PDP monitor. Related to the mounting structure.

[0002]

2. Description of the Related Art Problems of a conventional sirocco fan mounting structure will be described with reference to FIG. 2 showing an example of exhaust ventilation and a sirocco fan structure diagram of a conventional PDP monitor. (B) is a schematic perspective view of the sirocco fan.
The sirocco fan 1 includes a fan 5 having a number of rotating fins, a fan motor 3 for driving the fan to rotate, an inlet 6 flowing in from the axial direction, a guide portion 1A for flowing hot air in the axial direction and guiding it in the outer circumferential direction, This is a hot air discharge type fan configured with a discharge port 7 discharging in a specific direction.
The large-sized PDP monitor device 8 is manufactured in a thin structure, and the gas discharge type PDP consumes several hundred watts of power, so that the PDP, the driving circuit of the PDP, the power supply unit, and the like generate high temperatures. Therefore, the cooling of the PDP and the high-temperature part does not become natural cooling but constitutes a forced cooling system using an electric fan. An axial-flow type propeller fan is used as a general electric fan, but the sirocco fan 1, which has high exhaust efficiency and can be downsized, is used in the PDP monitor device 8 which has a large screen and is thin. . As shown in an example of exhaust air ventilation of a sirocco fan according to the prior art (a), the sirocco fan 1 is disposed above the PDP monitor device 8, and an exhaust air vent is also provided above the rear panel 8b. Ventilation inhalation on the back side is 8c
Or through a vent at the lower part of the back panel part 8b.

However, in the case of the multi-screen display system as shown in FIG. 2, the PDP monitor device 8 ′ arranged on the upper side uses the exhaust gas of a higher temperature than the PDP monitor device 8 ″ arranged on the lower side to ventilate the lower part. Due to the inhalation through the mouth, the internal cooling is incomplete and the internal temperature exceeds the maximum allowable value, and the interval between the PDP monitor devices 8 'and 8 arranged vertically must be made wider than necessary. The problem is that it is difficult to construct a multi-screen display system that displays on a single screen.In addition, in the case of a wall-mounted installation type that does not have sufficient exhaust space at the top, the exhaust ventilation resistance of the upper ventilation hole is large. Therefore, there is also a problem that the internal temperature easily exceeds the maximum allowable value.Therefore, as shown in (b), the outlet 7 of the sirocco fan 1 can be rotated in any direction as required. Proposal of the mounting structure of the fan there is a demand.
