Embodiment
Shown in 1 figure, the utility model power-supply radiator comprises rectangle heat radiation group sheet 1, and heat radiation group sheet 1 is an aluminum alloy materials.Heat radiation group sheet 1 surrounds a heat dissipation wind channel 6, the both-side opening of described heat dissipation wind channel, one side is an air inlet 2, opposite side is an air outlet 3, is provided with the buffering dividing plate at air outlet 3 places of heat dissipation wind channel, and the buffering dividing plate comprises buffering internal partition 4 and buffering external partition 5, buffering internal partition 4 is provided with hollow space, the air outlet 3 corresponding settings of this hollow space and heat dissipation wind channel 6, buffering external partition 5 is connected with fan 7, is provided with gasket seal 8 cushioning internal partition 4 and cushion between the external partition 5.
Be provided with the conducting strip 9 that the parallel pectination of many rows is provided with in heat dissipation wind channel 6, the wind direction of the direction of conducting strip 9 and fan 7 is consistent.
The power of air channel air-flow produces blast from the running of fan.
Aluminum alloy heat sink:
Constitute a heat dissipation wind channel 6 by aluminum alloy materials, as shown in Figure 2, form by a lot of pectination heat conduction aluminum alloy sheets in the heat dissipation wind channel 6, their direction is identical to reduce the resistance in air channel with the direction of air-flow, 4 planes of the upper and lower, left and right of heat radiation group sheet 1 polish flat bright and clean, and high-power heater members is installed on these 4 planes.
The air channel buffering area:
Form (as Fig. 1, shown in Figure 3) by inside and outside air channel buffering area dividing plate and gasket seal.For easy for installation, the buffering internal partition is installed on aluminium alloy heat radiation group sheet 1 with screw earlier, and then the buffering area external partition is installed, be lined with gasket seal 8 between two dividing plates to guarantee the air-tightness in air channel.It is enough big that the capacity of buffering area is wanted, with guarantee air-flow in the air channel evenly, reduce duct resistance, reduce the radiating efficiency in noise and raising air channel.
Fan:
Fan 7 is installed and is adopted air suction mode, to reduce the wind speed at air flow inlet place in the air channel, plays the kinetic energy that reduces dust particle in the air.
The characteristics in air channel:
It is point-blank substantially that the air channel exports from entering the mouth to, and the direction of the conducting strip in the fin air channel is parallel with the flow direction of air in the air channel, as far as possible near fairing, guarantees that like this resistance of air-flow is accomplished minimum.Fan adds cushion space between heat radiation group sheet, steadily even with the air-flow that guarantees the formation of fan rotation generation blast, improves the operating efficiency of fan, reduces noise.
