Abstract

The utility model provides a radiating structure of a multimedia device. The multimedia device is provided with a casing body, one side of the casing body is provided with a side cover, and the surface of the side cover is provided with a filter screen; a blower fan is arranged in the casing body, and the blower fan is opposite to the filter screen, and a filter membrane is clamped between the blower fan and the filter screen; after the multimedia device is started, cold air can be induced into the casing body after passing through the filter screen and the filter membrane due to the running of the blades of the blower fan of which the air is induced inwards, hardwares in the casing body are cooled, and the cold air induced into the casing body can be discharged from a broadcasting hole on the front surface of the casing body or from a radiating hole on the rear surface of the casing body. Due to the blades of the blower fan of the radiating structure of the multimedia device are reversely moulded, outside air can be blown into the multimedia device to achieve more effective radiation effect.

Description

The radiator structure of multimedia device

Technical field

The utility model relates to radiator structure, relates in particular to the radiator structure of multimedia device.

Background technology

General multimedia device, its inner hardware all can cause certain high temperature when running, the energy of this high temperature just can be stored in the hardware or reach in air, though this hardware high temperature more can not scalded the user, but often the time is untreated and just can reduces the smoothness that the hardware signal transmits, again even may make dangerous phenomenons such as the lower material of internal structure burning-point catches fire.

Therefore, the shell that prior art is convenient to this multimedia device is offered a peristome, and be equiped with a fan assembly with respect to this peristome in multimedia device inside, the heat energy that this multimedia device internal hardware can be produced by this fan assembly drains into the external world, and after getting rid of heat energy, extraneous cold wind just can be along distinguished and admirable by the slit between the textural association of multimedia device, or sees through the air-guiding hole that its shell offers and enter, for replenishing the air that is run off.

Yet, no matter whether existing multimedia device have this air-guiding hole, its heat extraction effect all can't reach the effect as expection, because though outside air can enter in this multimedia device smoothly, but, common air in entering this multimedia device can heat up immediately gradually, therefore can't reduce the high temperature of hardware effectively fast.

The utility model content

Problem for the radiating effect that solves above-mentioned multimedia device, the utility model provides a kind of radiator structure of multimedia device, comprise a housing, group is provided with a fan assembly in this housing, these fan assembly two opposite ends respectively are formed with a fixed part, the blade of this fan assembly is with respect to the prior art reverse molding, make that promptly the wind direction that is blown out is in reverse to the wind direction that this existing fan blows out, and this housing is provided with a side cover with respect to this radiator structure one side group, this side cover surface is formed with a peristome, and be provided with a screen pack in this peristome group, this screen pack is corresponding to this fan assembly, and and fan assembly between seized a filter membrane on both sides by the arms, in addition, this housing is formed with several broadcast holes in its front side surface, then is formed with several louvres in rear side surface.

Described fixed part is locked in this housing with self-tapping screw.

Described fixed part is mounted in this housing in the mode that fastens.

Compared with prior art, the utlity model has following beneficial effect:

The blade of fan assembly of the present utility model is with respect to the prior art reverse molding, and the air in the external world is seen through screen pack and filter membrane to multimedia device, and the direct various hardware of cooled interior; The air that is transmitted by the external world just can absorb the part high temperature of hardware, and through the outside air extruding of newly coming in, can be discharged outside this multimedia device by this broadcast hole and louvre smoothly, so, can reduce the high temperature of hardware apace.
