In Fig. 10, second fender 721 ' is near by the heat radiation buffer unit 7' " dust free area 8 limited; the second fender 722 ' is away from dust free area 8, and the second fender 721 ' and 722 ' is respectively provided with the second passage (being designated as 721a ' and 722a ' respectively) that the width along its place the second fender runs through.There is the second ventilation space 72a ' between adjacent two-layer the second fender 721 ' and 722 '.And the passage of adjacent two-layer the second fender 721 ' and 722 ' misses one another.Second passage 722a ', the second ventilation space 72a ' and the second passage 721a ' form gas channel.
In the present embodiment, thermal current in dust free area 8 is discharged to the outside of dust free area from the gas channel of the heat radiation top first paragraph 71 of buffer unit, and cold airflow dust free area outside enters into inside dust free area 8 through the gas channel of heat radiation buffer unit second segment 72 ' on the lower.Due to airflow direction straight up, therefore the effect of stack effect reaches maximum.
It should be noted that the number of plies of the second fender of the second segment 72 ' of the heat radiation buffer unit shown in Figure 10 is 2 layers, the structure more than 2 layer of second fender can also be adopted in practice.
Simultaneously, the difficulty within dust free area is entered into through gas channel in order to increase dust granules further, preferably, when heat radiation buffer unit is when the side of display floater right edge, in second segment 72 ' in the second fender of adjacent two layers, surface away from the second fender of side, dust free area forms dust collecting trough and the second passage of the open communication of dust collecting trough and the second fender in the face of close side, dust free area.For Figure 10, second fender 722 ' forms dust collecting trough 722b ' on the surface of the second fender 721 ', and the second passage 722a ' that the opening surface of dust collecting trough 722b ' is to the second fender 721 ', and the second passage 722a ' connection of the opening of dust collecting trough 722b ' and the second fender 721 '.So, outside dust granules along with air be flowed into gas channel time, dust granules can because inertia enters in dust collecting trough, and because self gravitation is not easily escaped from from dust collecting trough.
The present invention is been described by by above-mentioned related embodiment, but above-described embodiment is only the example implementing the present invention.It must be noted that, the embodiment disclosed is not limiting as the scope of the present invention.On the contrary, the change made without departing from the spirit and scope of the present invention and retouching, all belong to the scope of patent protection of the present invention.
