Abstract

A flat panel display with a panel for heat dissipation, comprising: a flat display panel for displaying an image; a frame for supporting the flat display panel; a printed circuit board on which a plurality of elements generating heat energy are disposed; the shell is used for accommodating the flat display panel, the frame and the printed circuit board; the panel is provided with a hole for accommodating the flat display panel and is divided into a lower side plate, an upper side plate, a left side plate and a right side plate, at least one air inlet is arranged at the lower side plate of the panel, and an air outlet is arranged at the upper side plate of the panel. It has better air inlet and outlet design, and can meet the requirement of embedding the flat panel display into the wall.

Description

The flat-panel screens of dispelling the heat with panel

Technical field

The present invention relates to a kind of display, especially a kind of flat-panel screens of dispelling the heat (flat panel display) with panel (front panel).

Background technology

Along with the progress of technology and the reduction of cost, flat-panel screens can replace a part of video picture tubular type (CRT) display gradually, and occupies sub-fraction market gradually.

And the plane formula display has roughly comprised plasma type display (Plasma DisplayPanel-PDP) and LCD (Liquid Crystal Display-LCD) or the like.

How the arrangement of the cooling mechanism of plasma scope at present introduces cold air by below, display back or below, side, then discharges hot-air by top, above the display back or side or by the back side.The inlet and outlet opening that is to say air is located on two Different Plane of display at least.

The characteristic of the wall embeded formula arrangement of display is the whole thickness of display is inserted in the slotted eye of a wall, and expose on only surplus next display panel plane.Traditional heat dissipation design obviously can not be installed on the flat-panel screens embedding in the wall owing to the factor of heat dissipation design.

Summary of the invention

For overcoming the problems referred to above, the object of the present invention is to provide a kind of flat-panel screens with improved heat dissipation design, it has better inlet and outlet design, can satisfy flat-panel screens is embedded requirement in the wall.

The invention provides a kind of flat-panel screens of dispelling the heat with front panel, comprising: a flat display board is used for show image; One frame is used to carry this flat display board; One printed circuit board (PCB), it is provided with a plurality of elements that can produce heat energy; One housing is used to hold described flat display board, frame, printed circuit board (PCB); One panel, offer a hole on it and be used to hold described flat display board, described panel is divided into lower side panel, epipleural, left and right side panel, it is characterized in that at least one air inlet being set at the lower side panel place of described panel, be provided with the column type cross flow fan at this air inlet place, in this frame arranged outside fan is arranged, exhaust outlet is set at the epipleural place of described panel.

Description of drawings

Fig. 2 is the cutaway view of flat-panel screens of the present invention along the 2-2 line;

Fig. 3 is the cutaway view of flat-panel screens of the present invention along the 3-3 line.

Embodiment

Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described.

As shown in Figure 1, 2, 3, flat-panel screens 10 of the present invention comprises flat display board (glass) 12, a panel 14, a frame 25 (with reference to figure 2), an after-frame 23 (with reference to figure 2), a bracing frame 17 (with reference to figure 2) of a rectangle.Offer a hole on the panel 14 for holding this flat display board 12.

Flat display board 12 provides the usefulness of show image, and it can be a LCD-type, also can be the plasma display pattern.Panel 14 is used to provide the modification of outward appearance, and suitable inlet and outlet mouth position is provided.Frame 25 is mainly upper and lower, left and right four frames and constitutes, and flat display board 12 is vertically set on the side of frame 25, supports, combines with the housing 26 of display by frame 25 then.Then be mounted with after-frame 23 on the opposite side of frame 25, after-frame 23 be used for protecting flat-panel screens internal printed circuit board 22 and on element 24.Bracing frame 17 combines with the backboard (rear panel) of flat display board, supports large-area flat display board 12.

As shown in Figure 1, flat-panel screens of the present invention is in the lower side of panel 14, and arranging has at least one air inlet 16, and cold air air inlet 16 thus enters, and is driven by its internal fan, and hot-air is discharged by steam vent 18.That is to say that air inlet 16 and exhaust outlet 18 all are arranged on the single panel 14, thereby reach purpose of the present invention.

In order to reach preferable inlet and outlet effect, air inlet 16 places in the space of the display housing 26 of flat-panel screens of the present invention are provided with column type cross flow fan 20, as shown in Figure 2.

One goggles, 19 (not shown in figure 1)s, display panel glass 12, bracing frame 17, frame 25, after-frame 23, printed circuit board (PCB) 22, housing 26, electronic component 24 are arranged shown in Fig. 2.Cold air is entered in the space that (as the direction of arrow) housing 26 constituted by the air inlet 16 of below, and advances along the direction of arrow, and the heat that electronic component 24 is produced is taken away, and is discharged by exhaust outlet 18.As shown in Figure 1, exhaust outlet 18 is arranged in the both sides and the upside of panel 14.

Fig. 3 illustrates the associated components of 3-3 hatching among Fig. 1.Goggles 19, after-frame 23, frame 25 (right side), frame 25 (left side), fan 30 are wherein arranged.Wherein fan 30 is arranged on the outside of frame 25, assists hot-air to discharge and make the flow through element of high temperature of air.In Fig. 3, for asking simple, display panel 12, circuit board 22, electronic component 24 etc. are all not shown.

As seen by above-mentioned, flat-panel screens of the present invention concentrates on one single the inlet and outlet opening of display, can satisfy flat-panel screens is embedded requirement in the wall, and better inlet and outlet design can be arranged.

More than the preferred embodiments of the present invention are described, but the present invention is not limited to this specific embodiment, those of ordinary skills can make other modification and modification and without departing from the spirit and scope of the present invention.Protection scope of the present invention should be defined by appended claims.
