The schema in accompanying drawing is refer to, wherein identical element numbers represent identical component.The following description is to be based on
Illustrated the utility model specific embodiment, it is not construed as limiting the utility model other specific realities not detailed herein
Apply example.
Referring to Fig.1 and 2, Fig. 1 is the knot of the preferred embodiment of remote control property cellular phone signal shielding device of the present utility model
Structure schematic diagram；Fig. 2 is heat sink, fin and the wind of the preferred embodiment of remote control property cellular phone signal shielding device of the present utility model
The structural representation of fan.
The remote control cellular phone signal shielding device of the present embodiment includes housing 11, circuit board 12, shroud module 13 and radiating knot
Structure.
Specifically, housing 11 includes the bottom plate 111 positioned at the bottom of housing 11；Circuit board 12 is arranged on the bottom plate in housing 11
On 111；Shroud module 13 is used to shield mobile phone signal, and it is set on the circuit board 12；Radiator structure is arranged on the outer of bottom plate 111
Side, it includes heat sink 14, case 15, fin and fan 17；
Heat sink 14 is fixedly connected on bottom plate 111, and it is connected by Heat Conduction Material 18 and circuit board 12；Case 15 covers at
The periphery of heat sink 14, case 15 and heat sink 14 define to form a heat-dissipating space；Fin is arranged on heat sink 14；Fan
17 are arranged on one end of fin 14, and the bottom in case 15；
Multiple heat conduction through holes are provided with bottom plate 111, Heat Conduction Material 18 is provided with heat conduction through hole, wherein, corresponding to screen
The number density for covering the heat conduction through hole set on the bottom plate 111 of the region of module 13 is more than the number density in other regions.
It should be noted that the number density of heat conduction through hole is expressed as the number of heat conduction through hole in unit area.
In the present embodiment, centralized radiating is carried out for shroud module 13, it is steady to improve the work of shroud module 13
It is qualitative, on the one hand it is because shroud module 13 is the groundwork module for shielding mobile phone signal, as long as the work of shroud module 13
Stabilize, the job stability of embodiment can be reached；On the other hand, such setting, the purpose of function piecemeal radiating is played,
Improve radiating efficiency and save cost again.
In addition, optional Heat Conduction Material 18 is one kind in heat conductive silica gel, heat conductive rubber or conductive filler glue.It is by
Heat at shroud module 13 conducts to heat sink 14 and distributed.
And the setting of fan 17, improve the radiating efficiency of radiator structure.
In the present embodiment, heat sink 14 is included corresponding to the first radiating area 141 of the region of shroud module 13 and right
Should be in second radiating area 142 in other regions, fin is divided into the first fin 161 for being arranged on the first radiating area 141 and set
Put the second fin 162 in the second radiating area 142；
First fin 161 is consistent with the bearing of trend of the second fin 162, and the distance between first fin 161
Less than the distance between second fin 162.
Such setting so that the quantity of the first fin 161 on the first radiating area 141 is more than the second radiating area 142
On the second fin 162 quantity, the radiating efficiency to shroud module 13 is improved, so as to improve the work of shroud module 13
Make stability.
Further, the first fin 161 and the second fin 162 are staggered setting.Such setting so that pass through second
Air-flow between fin 162 when entering the first fin 161, can be divided into by the first fin 161 two strands of air-flows and from
The both sides of first fin 161 are flowed through, and improve the time of contact of air-flow and the first fin 161, so as to improve radiating effect
Rate.
In addition, fan 17 is arranged on case 15 close to one end of the second fin 162, and outside the both sides of the second radiating area 142
The second fin 162 enclosed extends from close to one end of fan 17 towards the direction of fan 17；So that the second adjacent fin
A flow-guiding channel is formed between 162, is easy to the air-flow of fan 17 to rapidly enter the second radiating area 142 of periphery.
And second fin 162 define to form a cancave cambered surface close to the end face of one end of fan 17, fan 17 is located at concave arc
At the arc core in face.Such setting so that synchronous the second radiating area of entrance 142 that the air-flow that fan 17 is blown out can be balanced,
So as to improve the harmony of radiating.
In the present embodiment, case 15 also includes the substrate for being located at the bottom of case 15 and three surface sides for being arranged on substrate the week side of boss
Plate, three surface side plates and substrate form case 15；And case 15 and heat sink 14 define to form a radiating with side's opening 19
Space；
Wherein, it is arranged on the side plate at the back side of fan 17 and is provided with some air admission holes 151, the air-out direction face of fan 17
Opening 19.
Because air admission hole 151 and opening 19 are oppositely arranged so that air-flow passes through the second radiating area 142 and the first radiating area
141 path shortens, so as to improve radiating efficiency, on the other hand because the heat dissipation capacity of the first radiating area 141 is larger, therefore will
Opening 19 close to the first radiating area 141 setting, further shorten the first radiating area 141 by heat give out the external world when
Between, so as to improve radiating efficiency.
The radiation processes of embodiment are：
First, the shroud module 13 and other electronic components and circuit board 12 being arranged on the circuit board 12 in housing 11
Body heat production because of work, and shroud module 13 and other electronic components conduct heat to circuit board 12 simultaneously；
Then, the heat in circuit board 12 conducts the heat sink 14 into radiator structure through Heat Conduction Material 18, and heat sink
14 distribute a heat part in heat-dissipating space, and a branch conducts heat to the first fin 161 and the second fin
162, and distributed by the first fin 161 and the second fin 162 in heat-dissipating space；
Finally, fan 17 is worked, and air-flow is blowed to from air admission hole 151 to the second fin in the second radiating area 142, and will
Air with heat flows to the first radiating area 141 from the second radiating area 142, and with the heat in heat-dissipating space from opening 19
Place is distributed in the external world.
So just complete the radiation processes of the present embodiment.
Compared to the remote control cellular phone signal shielding device of prior art, remote control property cellular phone signal shielding device of the present utility model
By carrying out the arrangement of centralization to the signal shielding module for being directed to high heating of Heat Conduction Material and fin, this reality is improved
With new radiating efficiency and cost-effective；Solves the relatively low skill of the heat dispersion of existing remote control property cellular phone signal shielding device
Art problem.
In summary, although the utility model is disclosed above with preferred embodiment, above preferred embodiment is not used
To limit the utility model, one of ordinary skill in the art, do not departing from spirit and scope of the present utility model, can make
Various changes and retouching, therefore the scope of protection of the utility model is defined by the scope that claim defines.
