Embodiment
Below in conjunction with Figure of description, the utility model is described further:
A kind of electric automobile battery charger wind-cooling heat dissipating mechanism, comprise housing 1, cover plate 2, gland 4 and fan 3, housing 1 forms components and parts thermal source chamber 5 with gland 4, interior components and parts and the wiring board of arranging in components and parts thermal source chamber 5, housing 1 forms heat radiation chamber 6 with cover plate 2, in heat radiation chamber 6, some fin 7(being evenly set is side by side fin), adjacent fin 7 forms air channel 8, the inlet side in air channel 8 arranges fan 3, fan 3 is fixed on cover plate 2, the air side in air channel 8 is communicated with atmosphere, wind in cover plate 2 Main Function Shi Shi air channels flows towards a direction, be the wind of the fan generation of inlet side, along air channel, to air-out, sidle, and finally from air side, discharge.
Components and parts thermal source chamber 5 is not communicated with heat radiation chamber 6, and the fin 7 by heat radiation chamber 6 interior settings increases area of dissipations, and fin 7 be waveform, thereby make air channel, is also waveform, increases the time of stop in Feng air channel, takes away to greatest extent heat; The two sides of fin 7 are light face or toothed surface, and toothed surface is to increase contact area, and the cross section in air channel can be set to square or semicircle as required.
Air channel is waveform, and when fan blows into from inlet side, wind will enter by waveform air channel, takes away the heat on wave shaped radiator, through helical wave several times, out from air side finally.Fin effect is to increase area of dissipation, takes away fast heat.
Conventionally the air quantity of fan has a minimum value, and in order to ensure reaching radiating effect, air quantity is generally greater than 32CFM, and preferably the 1-2 of minimum air quantity is doubly best.
In order to improve the resistance to elevated temperatures in heat radiation chamber, can high temperature resistant silver powder enamelled coating be set in the inner surface spraying in heat radiation chamber; Between gland and housing, sealing ring is set, prevents that liquid from flowing into components and parts thermal source chamber.
It is naturally cooling or air-cooled, easy for installation again that the utility model adopts waveform, cross section to be that square or semicircular air channel replaces single straight line fin, increased crushing resistance, increasing heat radiation area, and raising cooling effectiveness, has avoided amount of localized heat to accumulate phenomenon.
