Fig. 3 is the vertical view of preferred embodiment involved radiating module 100.Radiating module 100 has the first imaginary line 71 and the second imaginary line 72.First imaginary line 71 is parallel with the direction of the air flowed in conduit 5 and passes the imaginary line of stream central authorities.Second imaginary line 72 is through central axis J1 and the imaginary line vertical with exhaust outlet 36.First imaginary line 71 is passing through with the second imaginary line 72 to be the side that benchmark is contrary with tongue 321 by the position of exhaust outlet 36 side than central axis J1.
Fan 1 vertically air-breathing is also radially vented.The air sucked vertically is by changing flow velocity direction towards radial outside after air entry 51.In the utility model, because the air inhaled to air entry 51 has towards the velocity component of radial outside, the flow direction therefore without the need to changing air significantly just can be inhaled into.That is, without the need to providing useless energy just can be inhaled into and discharge, therefore, it is possible to discharge air efficiently to air.Thus, even the centrifugal fan of small-sized and low static pressure, with also can making smooth air by conduit 5.Thereby, it is possible to make to distribute from the heat of the thermal source 6 with conduit 5 thermo-contact by air cooling.
Impeller 4 rotates towards downstream for most upstream with tongue 321.Impeller 4 rotates the air stream produced and flows to downstream through the stream sidewall portion 32 and impeller 4.Along with by stream between sidewall portion 32 and impeller 4 of the air of air entry 51 towards downstream, the amount of the air of flowing increases, and discharges air from exhaust outlet 36.Now, near the exhaust outlet 36 of discharging air, the flow velocity of air is accelerated.That is, flow velocity is accelerated from upstream towards downstream.Flow velocity is faster, and air becomes negative pressure, and the inspiratory capacity from air entry 51 is just more.That is, the inspiratory capacity at the position of the close exhaust outlet 36 of air entry 51 increases.Further, the air stream produced by impeller 4 is sucked vertically, provides centrifugal force by impeller 4 to air, becomes towards the air-flow of radial outside.Be preferably the air-flow of position towards the direction of exhaust outlet 36 of the close exhaust outlet 36 increased from the inspiratory capacity of air entry 51 by the air stream of air entry 51 from conduit 5.First imaginary line 71 is by being the side that benchmark is contrary with tongue 321 with the second imaginary line 72, and flow towards the flow direction of exhaust outlet 36 in the air position of close exhaust outlet 36 of increasing along the inspiratory capacity from air entry 51 thus.Thus, the inertia force of the flowing in conduit 5 of air is combined with the centrifugal force produced by impeller 4, discharges from exhaust outlet 36 in the mode not against the flowing of air.That is, discharge from exhaust outlet 36 with flowing through the Efficient air of conduit 5.
About the position of the close exhaust outlet 36 of air entry 51, the position inspiratory capacity being especially positioned at the side contrary with tongue 321 relative to the second imaginary line 72 increases.That is, flowed towards this region from conduit 5 by air, discharge from exhaust outlet 36 in the mode not against the flowing of air.Further, owing to easily making the flow velocity direction of the air of discharging from exhaust outlet 36 consistent with the direction that conduit 5 extends, discharge from exhaust outlet 36 with therefore flowing through the Efficient air of conduit 5.
Radiating module 100 also has the 3rd imaginary line 73.3rd imaginary line 73 is through central axis J1 and the imaginary line parallel with exhaust outlet 36.Preferably the first imaginary line 71 is by between the second imaginary line 72 and the 3rd imaginary line 73.
With the first imaginary line 71 by the mode deployment catheter 5 between the second imaginary line 72 and the 3rd imaginary line 73, flow towards the flow direction of exhaust outlet 36 in the position of the close exhaust outlet 36 making air increase along the inspiratory capacity from air entry 51 thus further.Flowed towards this region from conduit 5 by air, discharge from exhaust outlet 36 in the mode not against the flowing of air.Further, owing to easily making the flow velocity direction of discharging air from exhaust outlet 36 consistent with the direction that conduit 5 extends, the air therefore flowing through conduit 5 is discharged from exhaust outlet 36 further efficiently.
Radiating module 100 also has the 4th imaginary line 74.4th imaginary line 74 is the imaginary lines of the end connecting the central axis J1 side contrary with the same tongue 321 of exhaust outlet 36.Preferably the first imaginary line 71 passes through between the second imaginary line 72 and the 4th imaginary line 74 further.
With the first imaginary line 71 by the mode deployment catheter 5 between the second imaginary line 72 and the 4th imaginary line 74, flow towards the flow direction of exhaust outlet 36 in the position of the close exhaust outlet 36 making air increase along the inspiratory capacity from air entry 51 thus further.Flowed towards this region from conduit 5 by air, discharge from exhaust outlet 36 in the mode not against the flowing of air.Further, owing to easily making the flow velocity direction of discharging air from exhaust outlet 36 consistent with the direction that conduit 5 extends, the air therefore flowing through conduit 5 is discharged from exhaust outlet 36 further efficiently.
Conduit 5 extends towards the side contrary with exhaust outlet 36 between the second imaginary line 72 with the 3rd imaginary line 73.
By air from conduit 5 towards the region flowing that the particularly inspiratory capacity of air entry 51 is more, and discharge from exhaust outlet 36 in the mode not against the flowing of air.Further, owing to easily making the flow velocity direction of discharging air from exhaust outlet 36 consistent with the direction that conduit 5 extends, discharge from exhaust outlet 36 with therefore flowing through the Efficient air of conduit 5.
Conduit 5 diametrically towards leave central axis J1 direction extend, conduit 5 relative to the direction vertical with exhaust outlet 36 centered by central axis J1 with exhaust outlet 36 side for starting point to tongue 321 side towards more than 90 degree and the direction of less than 180 degree extend.
Flow path area in the cross section vertical with path direction of conduit 5 is less than the area of air entry 51.
When the flow path area of conduit 5 is large and the air quantity of fan 1 is little, in conduit 5, the flow velocity of the air of flowing is slack-off.Further, when the flow path area of conduit 5 is large, the temperature near the inner peripheral surface becoming conduit 5 is the situation that rises of local easily, and the air entirety in conduit 5 not easily affects cooling characteristics.If there is above-mentioned flow velocity this problem comparatively slow simultaneously, then only have the temperature near the inner peripheral surface of conduit 5 to rise relative to slower air stream, consider this point, the flow path area of preferred conduit 5 is little.
By making the flow path area of conduit 5 less than the area of air entry 51, the flowing high speed of the air in conduit 5 can be made.The specific heat of the specific heat ratio metal of air is high.That is, even if give a small amount of air by heat trnasfer, temperature rises also little.Thus, tail off by making the air in conduit 5 thus make air high-speed circulating, the air of low temperature can be made at conduit 5 Inner eycle, and the heat being passed to conduit 5 is distributed.
Further, in the present embodiment, the area of preferred flow path area ratio exhaust outlet 36 is little.
Fan 1 is little by the area of the area ratio air entry 51 making exhaust outlet 36, accelerates the flow velocity of the air stream of discharge.By making the flow path area of conduit 5 less than the area of exhaust outlet 36, the flow velocity of the air of flowing in conduit 5 can be accelerated, thus the radiating effect of the heat being passed to conduit 5 can be improved.
Flow path shape in the cross section vertical with path direction of conduit 5 is the width in the direction vertical with central axis J1 and the path direction flat pattern longer than axial height.
The heat being passed to conduit 5 is passed to the inner peripheral surface of conduit 5, and is dispelled the heat by flowing through of air.Such as, when conduit 5 being set to the rounded tubulose in cross section, although the air near the inner peripheral surface of conductive pipe 5 carries out heat trnasfer, the heat being passed to conduit 5 is not easily passed to the air near the central authorities of stream.Flat pattern is set to, being increased by the ratio of the air near the inner peripheral surface of conduit 5 in the air passed through in stream by the cross section of the stream by conduit 5.That is, easily distribute by air the heat being passed to conduit 5.
The axial height of the air flow circuit in conduit 5 is lower than the axial height of exhaust outlet 36.
Conduit 5 extends towards the direction leaving central axis J1 diametrically.Conduit 5 relative to the direction vertical with exhaust outlet 36 centered by central axis J1 with exhaust outlet 36 side for starting point towards more than 90 degree and the direction of less than 270 degree extend.
Impeller 4 rotates towards downstream for most upstream with tongue 321.Impeller 4 rotates the air stream produced and flows to downstream through the stream sidewall portion 32 and impeller 4.Along with by stream between sidewall portion 32 and impeller 4 of the air of air entry 51 towards downstream, the amount of the air of flowing increases, and discharges air from exhaust outlet 36.Now, near the exhaust outlet 36 of discharging air, the flow velocity of air is accelerated.That is, flow velocity is accelerated from upstream towards downstream.Flow velocity is faster, and air becomes negative pressure, and the inspiratory capacity from air entry 51 is just more.That is, the inspiratory capacity at the position of the close exhaust outlet 36 of air entry 51 increases.Further, the air stream produced by impeller 4 is sucked vertically, provides centrifugal force by impeller 4 to air, becomes towards the air-flow of radial outside.
Be preferably the air-flow of position towards the direction of exhaust outlet 36 of the close exhaust outlet 36 increased from the inspiratory capacity of air entry 51 by the air stream of air entry 51 from conduit 5.By conduit 5 relative to the direction vertical with exhaust outlet 36 centered by central axis J1 towards more than 90 degree and the direction of less than 270 degree extend, air flows along the position of the close exhaust outlet 36 from air entry 51 towards the flow direction of exhaust outlet 36.Thus, the inertia force of the flowing in conduit 5 of air is combined with the centrifugal force produced by impeller 4, discharges from exhaust outlet 36 in the mode not against the flowing of air.That is, discharge from exhaust outlet 36 with flowing through the Efficient air of conduit 5.
Radiating module involved by the utility model can be used in the cooling of the equipment of the electronic equipment internal of notebook computer or desktop computer, the cooling of other equipment and provides air etc. to various object.Further, can be used in other purposes.
Further, each key element occurred in above-mentioned execution mode or variation can be carried out appropriately combined in the scope not producing contradiction.
Preferred implementation of the present utility model according to the above description can be thought, the distortion and the change that do not exceed scope and spirit of the present utility model are to those skilled in the art obvious.Therefore scope of the present utility model is determined by these claims uniquely.
