Abstract

The invention discloses an electronic device, which comprises the following parts: case, channel and multiple first fans, wherein the case has internal space; the channel is set in the internal space; multiple first fans are cascaded in the channel, which can maintain lower rotary speed to reduce noise effectively.

Description

Electronic installation
Technical field
The present invention relates to a kind of electronic installation as projector module and so on, its fan that utilizes series connection to be provided with can reduce overall noise.
Background technology
Usually, in projector module, be provided with fan dispelling the heat, and reach the purpose of cooling.In the configuration of existing projector module, a desk fan generally only is set, perhaps be arranged in parallel the fan more than, to strengthen air quantity.
Yet, can strengthen air quantity though increase number of fans, reach the effect of fast cooling, the noise that fan produced also increases relatively.How to realize not only improving air quantity but also do not increase the main consideration point that noise has become the design projector module.
Summary of the invention
Given this, the object of the present invention is to provide and a kind ofly can improve the electronic installation that air quantity does not increase noise again.
Electronic installation provided by the present invention comprises housing, passage and many first fans.Housing has the inner space, and passage is arranged in the inner space, and many first fans in series are arranged in the passage.
In an embodiment, electronic installation also comprises second fan, and housing comprises air inlet, and second fan is arranged at the position of contiguous air inlet.
In another embodiment, second fan is arranged between air inlet and the passage.
In another embodiment, second fan has air intake surface and outlet air surface, and air intake surface is in the face of air inlet, and the part of outlet air surface is in the face of passage.
In an embodiment again, electronic installation also comprises the thermal source that is arranged in the passage.
In another embodiment, thermal source is a light source.
In another embodiment, two desk fans are set, they are placed in the both sides of thermal source respectively.
In an embodiment again, electronic installation is a projector.
In another embodiment, electronic installation also comprises ray machine, and passage is arranged at a side of ray machine.

Embodiment
Referring to Fig. 1, in this embodiment, electronic installation of the present invention is a projector module 10, employed large projector in the meeting particularly, it comprises housing 11, passage 12, light source L, ray machine E, two first fan F1, the second fan F2 and fan blower F3, its middle shell 11 has internal space S.
Housing 11 has air inlet 111 and air outlet 112, passage 12 is for being arranged at the coolant flow channel in the internal space S, it is used for the hot-air that projector module 10 is produced in work is discharged the outside of housing 11, passage has first port one 21 and second port one 22, wherein first port one 21 and second port one 22 respectively correspondence be arranged at air inlet 111 and air outlet 112 places, and walk around from the side of ray machine E.
Light source L is a heater element main in the projector module 10, and it is set in the passage 12, and the first fan F1 also is set in the passage 12, and its mode with series connection lays respectively at the both sides of light source L.
The second fan F2 is set in the internal space S, its position between air inlet 111 and passage first port one 21, and have air intake surface F21 and outlet air surface F22, air intake surface F21 is in the face of air inlet 111, and the part of outlet air surface F22 is in the face of first port one 21 of passage.
Fan blower F3 is set in the internal space S, and it generally is configured to contiguous light source L, is used in particular for light source is dispelled the heat.
Wind enters housing 11 by air inlet 111, through the second fan F2, part wind is imported into passage 12, part wind is imported into internal space S (shown in arrow among Fig. 1), the wind of admission passage flow through in regular turn first first fan F1, light source L and second first fan F1 are discharged by air outlet 112 at last.The wind that enters the inner space heat radiation that can circulate to other assembly in the internal space S.
In projector 10 of the present invention, the first fan F1 is arranged in the passage 12 by series connection, and cooperation reduces the rotating speed of this fan, not only can increase air quantity, also can reduce noise.That is to say, for making system held in uniform temperature, needing set air quantity dispels the heat, as providing this set air quantity by a single desk fan, need make fan maintain high rotational speed, noise is also higher thereupon, provide identical set air quantity as the many desk fans that are provided with by means of series connection, the fan that these series connection are provided with can be kept lower rotating speed, so, just can reach the effect that reduces noise.
Can drop to minimum by suitable selection fan dimension, good design and the influence of controlling fan noise.Cardinal rule is in the peak operating efficiency scope, selects to satisfy the fan dimension of institute's required airflow and pressure.Therefore, if cooperate suitable condition, for example in passage 12, be equipped with the first fan F1 that small one and large one different size and series connection are provided with, only need a little its rotating speed to be reduced, just can provide the air quantity that produces greater than single fan, and make the noise that is produced less than single fan.
Though the present invention discloses as above with preferred implementation; but this is not in order to limit the present invention; the any technician in this area is under the prerequisite that does not exceed design of the present invention and scope; can make some conversion and retouching, so protection scope of the present invention should be as the criterion with the claims restricted portion.
