Further, the first air duct is crossing with the second air duct, to form heat loss through convection, improves radiating efficiency.
Be appreciated that in other embodiments, this radiator fan 50 can also be scavenger fan, for being discharged from described exhaust outlet 111 by the air-flow of this housing 10 inside.
See also Fig. 5, in the present embodiment, described radiator 70 is heat-conducting plate.Described radiator 70 is roughly in " L " matrix shape, and it is pasted by the Heat Conduction Material such as heat conductive silica gel, heat-conducting silicone grease and is fixed on this electronic component 41-49, for carrying out auxiliary heat dissipation to described electronic installation 100 entirety.Certainly, in other embodiments, the shape of this radiator 70 and structure also can adjust accordingly according to the position of the electronic component be laid on this substrate 30.Such as, when being arranged on the entirety of the electronic component on this substrate 30 in " U " type structural arrangement, described radiator 70 also can be " U " matrix shape.
Be appreciated that, when being arranged at the electronic component on substrate 30, when such as, having the electronic component to temperature is more responsive in electronic component 42-49, described radiator 70 also can be the described electronic component more responsive to temperature and arranges corresponding radiating fin, effectively to improve the radiating efficiency of the described electronic component more responsive to temperature.Such as, in the present embodiment, multiple electronic component more responsive to temperature is provided with in described electronic component 41-49, such as electronic component 45,48,49.Therefore, on described radiator 70, the position of the corresponding described electronic component 45,48,49 more responsive to temperature is provided with the first radiating fin group 71 and the second radiating fin group 73.First radiating fin group 71 and the second radiating fin group 73 are all located at described radiator 70 and deviate from the surface of described electronic component 42-49.Be appreciated that described radiating fin group can be arranged along the airintake direction of described first air entry 151 and/or the second air entry 153, to improve its radiating efficiency further.Such as, in an embodiment, described first radiating fin group 71 entirety is arranged along the airintake direction of described first air entry 151, and described second radiating fin group 73 entirety is arranged along the airintake direction of described second air entry 153.
See also Fig. 6, in the electronic installation 100 of the present embodiment, its housing 10, substrate 30, radiator fan 50 and radiator 70 form radiator structure jointly.When described radiator fan 50 works, the air of flowing enters described receiving space 17 by the first air entry 151 and the second air entry 153, and blow to corresponding electronic component respectively along two different air ducts, then by described exhaust outlet 111, the heat that described electronic component 41-49 produces is derived fast.Concrete, when the air flowed enters the first air duct by the first air entry 151, the air of described flowing will flow through and directly acts on the electronic component be arranged in the first air duct, to take away the heat that this electronic component produces, and arrives radiator 70.Meanwhile, when the air flowed enters the second air duct by the second air entry 153, the air of described flowing will flow through and directly acts on the electronic component be arranged in the second air duct, to take away the heat of this electronic component, and arrives radiator 70.Described radiator 70 converges the heat from the first air duct and the second air duct, and carries out heat convection with described radiator fan 50, and then is discharged through described exhaust outlet 111 by the heat that described electronic component 41-49 produces.
In addition, due to described radiator 70 being provided with radiating fin, therefore the radiating efficiency of its corresponding electronic component can be accelerated, make its temperature lower than the temperature not having correspondence to arrange the electronic component of radiating fin, and then guarantee that the electronic component of different temperatures sensitiveness all can well be dispelled the heat, effectively can reduce system wind resistance, to reduce the noise of this electronic installation 100 simultaneously.
Fig. 7 is the Temperature Distribution analogous diagram of each electronic component in electronic installation 100, and wherein more to deeply feel temp. displaying function higher for color.Obviously, above-mentioned radiator structure and there is this radiator structure electronic installation 100 by arranging two air entries and exhaust outlet, the radiating layout of formation like this " two enter one goes out ", the heat of this housing 10 inside is conducive to all to be discharged, and improve radiating efficiency, thus without the need to heat-pipe radiator, such that the structure of this radiator structure is simple and cost is lower.In addition, because described electronic component 41-49 is all arranged near two air entries, after air so can be made to enter from two air entries, directly flow through electronic component, and then high efficiency and heat radiation.Meanwhile, because described electronic component 41-49 separates layout, such as, be separately positioned in different air ducts, so can make full use of product structure space, effectively reduce density of heat flow rate.Again, described radiator 70 only arranges radiating fin group near temperature sensitive electronic component, so can effectively reduce system wind resistance, to reduce the noise of this electronic installation 100.
Be appreciated that in other embodiments, the cold air of outside also can suck from described exhaust outlet 111 by described radiator fan 50, then discharges respectively by described first air entry 151 and the second air entry 153.That is, above-mentioned wind path can reverse by this electronic installation 100, by original exhaust outlet 111 as inlet port, and using the first original air entry 151 and the second air entry 153 as exhaust outlet, to form the radiator structure of " enters scene 2 ", and then reach same radiating effect.
Be appreciated that, the quantity of described air entry can be not limited to two in the present embodiment, it can adjust according to actual conditions, such as, only arrange an air entry (first air entry 151 or the second air entry 153), or arrange more than three or three air entries.Accordingly, described air entry can form the air duct of, more than three or three with this exhaust outlet 111.
