Abstract
The utility model discloses a charger, including the casing, install heating element and radiator fan on the casing, characterized by: still be fixed with the heat dissipation mainboard on the casing, heating element closely laminates on the heat dissipation mainboard, it has a plurality of radiating fin still to arrange on the heat dissipation mainboard, is formed with heat dissipation chamber way between adjacent radiating fin, and the heat dissipation chamber says that both ends form air inlet end and air -out end respectively, and it is right that the air inlet is correcied radiator fan. This scheme provides the charger that the radiating effect is good.
Description
Technical field
The utility model relates to a kind of charger, belongs to electric product field.
Background technology
Charger is used to the articles for use of accumulators product charging, because inside needs through energy transferring, usually has larger caloric value, needs effectively to dispel the heat.Although conventional charger all arranges radiator fan, its radiating effect is limited, and inner member is still frequent due to high temperature appearance damage, causes charger normally to work.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the charger providing a kind of radiating effect excellent.
For achieving the above object, the utility model provides following technical scheme: a kind of charger, comprise housing, housing is provided with heater element and radiator fan, described housing is also fixed with heat-dissipating main, described heater element fits tightly on heat-dissipating main, described heat-dissipating main is also arranged with some radiating fins, be formed with heat radiation cavity between adjacent heat radiation fin, heat radiation cavity two ends form air intake and outlet air end respectively, and air intake is rectified described radiator fan.
Preferably, described heat-dissipating main is vertical with radiating fin to be arranged, and radiating fin thickness is thinning gradually from the root of radiating fin to top.
Preferably, described cooling fin surfaces is provided with some fins, and fin extends from air intake to outlet air end direction.
Preferably, described heat-dissipating main and radiating fin are wholely set.
Preferably, described heat-dissipating main top is provided with dust cover, and dust cover orthographic projection covers described radiating fin.
Compared with prior art, the beneficial effects of the utility model are: heater element is owing to being close on heat-dissipating main, can fast heat be delivered on heat-dissipating main, heat-dissipating main continues heat to be delivered on radiating fin, the surface area utilizing radiating fin larger realizes quick heat radiating, because radiator fan is just to the air intake of radiating fin, the air flowing of cooling fin surfaces can be accelerated.Program radiating effect compares the simple structure by fan cooling of tradition, can available protecting heat dissipation element, makes its fast cooling.

Fig. 3 is the enlarged drawing at A place in the utility model Fig. 2.
Reference numeral: 1, housing; 2, radiator fan; 3, heater element; 4, heat-dissipating main; 5, radiating fin; 5a, fin; 6, air intake; 7, outlet air end; 8, dust cover.
Embodiment
A kind of charger, comprise housing 1, housing 1 is provided with heater element 3 and radiator fan 2, described housing 1 is also fixed with heat-dissipating main 4, described heater element 3 fits tightly on heat-dissipating main 4, described heat-dissipating main 4 is also arranged with some radiating fins 5, is formed with heat radiation cavity between adjacent heat radiation fin 5, heat radiation cavity two ends form air intake 6 and outlet air end 7 respectively, and air intake 6 is just to described radiator fan 2.Heater element 3 is owing to being close on heat-dissipating main 4, can fast heat be delivered on heat-dissipating main 4, heat-dissipating main 4 continues heat to be delivered on radiating fin 5, the larger surface area of radiating fin 5 is utilized to realize quick heat radiating, because radiator fan 2 is just to the air intake 6 of radiating fin 5, the air flowing on radiating fin 5 surface can be accelerated.Program radiating effect compares the simple structure by fan cooling of tradition, can available protecting heat dissipation element, makes its fast cooling.Here heat dissipation element may be the electrical equipment of the various heat radiation such as transformer, flow straightener.
Wherein, heat-dissipating main 4 is vertical with radiating fin 5 to be arranged, and radiating fin 5 thickness is thinning gradually from the root of radiating fin 5 to top.First benefit of such setting strengthens the bond strength of radiating fin 5 at heat-dissipating main 4, difficult drop-off and distortion; Second benefit is the surface radiating area increasing radiating fin 5, and this is that relative radiating fin 5 vertically stretches out this effect, must tilt simultaneously, can prevent dust accretions owing to disputing its surface.
Wherein, radiating fin 5 surface is provided with some fin 5a, and fin 5a extends from air intake 6 to outlet air end 7 direction.Have fin 5a to form depression, the area of dissipation of such radiating fin 5 strengthens further, and radiating effect strengthens further.
Wherein, heat-dissipating main 4 and radiating fin 5 are wholely set.Be wholely set and radiating fin 5 intensity on heat-dissipating main 4 can be allowed higher, both can adopt die cast also can be one-body molded in later stage machine work.
Wherein, heat-dissipating main 4 top is provided with dust cover 8, and dust cover 8 orthographic projection covers described radiating fin 5.Dust cover 8 can avoid the too much dust of radiating fin 5 surface sediment, especially after radiating fin 5 offering fin 5a, dust is more easily piled up, and dust cover 8 can alleviate the appearance of this problem very well, fin 5a also can be set at dust cover 8 lower surface realize heat sinking function together with radiating fin 5, a burnishing surface is arranged to, its surface dirt of easy cleaning in the suggestion of dust cover 8 upper surface.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
