Embodiment
Please be simultaneously with reference to Fig. 1, Fig. 2, Fig. 1 illustrates the stereographic map according to a kind of radiating module of the utility model one embodiment, and the radiating module that Fig. 2 illustrates Fig. 1 is loaded onto the stereographic map behind the fan.Radiating module 100 is mainly by array radiating fin modules 110, heat pipe (101; 103) and 120 formations of centrifugal fan.Heat pipe (101; 103) a end is connected in a side of array radiating fin modules 110, and the other end is connected in the pyrotoxin that needs heat radiation, arrives array radiating fin modules 110 in order to the heat conduction that pyrotoxin is produced.120 of centrifugal fans are taken away the heat on the radiating fin in order to output gas flow to array radiating fin modules 110.
Array radiating fin modules 110 is arranged by multi-disc radiating fin almost parallel and is constituted, and its function increases area of dissipation exactly.Each radiating fin is a strip, and its length L is greater than its height H.Array radiating fin modules 110 has along the air intake vent 110a of its long axis direction and the first air outlet 110c.The outgassing direction 150 of the long axis direction almost parallel centrifugal fan 120 of array radiating fin modules 110 can be exported the air-flow of centrifugal fan 120 along the long axis direction of array radiating fin modules 110.Array radiating fin modules 110 has one second air outlet 110b in addition, and the second air outlet 110b and heat pipe (101; 103) be positioned at the two opposite sides of array radiating fin modules 110.
In the present embodiment, the second air outlet 110b is positioned at the top margin of array radiating fin modules 110, and the distance first air outlet 110c is near apart from air intake vent 110a.The second air outlet 110b also can apart from the first air outlet 110c with equate apart from air intake vent 110a.Under the considering of usefulness, the second air outlet 110b distance first air outlet 110c design near than air intake vent 110a, the usefulness of array radiating fin modules 110 is preferable.Another considers the louvre of the position need corresponding housing that is the second air outlet 110b.
On the top margin of array radiating fin modules 110, a barricade 112 also can be set, be used to stop that the thermal current adverse current of first air outlet 110c output is returned in the housing, be unfavorable for the usefulness of dispelling the heat.In the present embodiment, barricade 112 is between the first air outlet 110c and the second air outlet 110b.In another embodiment; Also can set up another barricade 112 on the top margin of array radiating fin modules 110; And between the air intake vent 110a and the second air outlet 110b (not being illustrated in drawing); The thermal current that is used to stop second air outlet 110b output is inhaled back air intake vent 110a, is unfavorable for the usefulness of dispelling the heat.Barricade 112 and heat pipe (101; 103) be positioned at the two opposite sides of array radiating fin modules 110.Barricade 112 material can be non-metallic spring material, rubber etc. for example.
The gas outlet 120b of centrifugal fan 120 is connected to the air intake vent 110a of array radiating fin modules 110.In principle, the size of the gas outlet 120b of centrifugal fan 120 equals the air intake vent 110a size of array radiating fin modules 110, can make the usefulness of radiating module 100 best.When centrifugal fan 120 runnings, air-flow gets into from axial air intake 120a, is exported to the air intake vent 110a of array radiating fin modules 110 by gas outlet 120 radially.
Heat pipe (101; 103) a end is connected in a side of array radiating fin modules 110, and the other end is connected in the pyrotoxin that needs heat radiation.In the present embodiment, an end of heat pipe 101 is connected to CPU heat radiation block 102.CPU heat radiation block 102 also utilizes heat radiation paster 104 and screw 102a that it can be close proximity on the cpu chip, takes away the heat energy of generation rapidly.Heat pipe (101; 103) be connected in other chip cooling blocks 105 simultaneously in order to pyrotoxins such as heat radiation display chip, north bridge chips, south emigrant's chips.Other chip cooling blocks 105 also have with heat radiation paster 106 and screw 105a makes it can be close proximity to corresponding chip surface, increases heat dissipation.
" air intake vent adds the design of two air outlets " of above-mentioned array radiating fin modules 110, have preferable heat dissipation compared to " air intake vent adds the design of an air outlet " in experiment.In experiment, the heat radiation power 36W of " air intake vent adds an air outlet " further the is promoted to heat radiation power 38.1W of " air intake vent adds two air outlets ".CPU also drops to 90.1 degree (adding at an air intake vent under the design of two air outlets) at maximum temperature 93.32 degree (adding at an air intake vent under the design of an air outlet) of full load; Reduced by 3.2 degree, it serves to show in the array radiating fin modules to increase the lifting that an air outlet helps radiating module efficient in addition.
Can know that by above-mentioned the utility model embodiment the radiating module of using the utility model utilizes " air intake vent adds the design of two air outlets " of its array radiating fin modules, makes the air-out efficient of radiating module better, helps the lifting of radiating module efficient.
