A kind of power supply adaptor that can effectively radiateTechnical field
The utility model is related to power supply adaptor technical field, more particularly to a kind of power supply adaptor that can effectively radiate.
Background technology
Power supply adaptor is the power supply conversion equipment of electronic equipment and electronic apparatus, typically by outer casing of power supply, power supplyTransformer and rectification circuit composition, at present, due to there is no special heat dissipation equipment on power supply adaptor, with user it is long whenBetween use, adapter circuit will produce substantial amounts of heat in power supply adaptor, if radiated not in time, can influence itThe job stability of internal electron circuit, causes the stability of its output voltage to be affected, and then have influence on electronic equipmentService behaviour and its life-span, and the long-term electronics also easily having influence on inside it that worked in the environment of heating of power supply adaptorThe life-span of component.
The line footpath of the enamel-covered wire of primary coil in power transformer is general relatively thin, causes primary voltage high, electricStream is low, and the line diameter ratio primary coil line footpath of secondary coil is big, causes secondary current high, easily heating inside line bag, noEasy heat radiation, makes coil expansion cause line bag to become fat, influences the normal work and use life-span of power transformer.In order that radiating effectReally good, design principle now is to widen winding slot, and to cause line bag good heat dissipation effect, but such a design but makes coiling boneFrame is widened, and consumable material resource will be more, and internal heat, which is distributed, not to be solved fundamentally but.

Implement the technical scheme for the power supply adaptor that the utility model can effectively radiate, have the following advantages that or beneficial effectReally：The radiator for the power supply adaptor that the utility model can effectively radiate the heat of generation can be carried out it is effective distribute, it is realNow to the high efficiency and heat radiation of adapter, radiating effect is good, significantly improves the radiating condition of supply convertor, prevents power supply from fittingThe temperature of orchestration itself is too high and influences the normal work and use life-span of whole power supply adaptor.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme of the utility model embodiment, required in being described below to embodimentThe accompanying drawing used is briefly described, it is therefore apparent that drawings in the following description are only some embodiments of the present utility model,For those of ordinary skill in the art, on the premise of not paying creative work, it can also be obtained according to these accompanying drawingsIn other accompanying drawings, accompanying drawing：
Fig. 1 is the structural representation for the power supply adaptor embodiment that the utility model can effectively radiate.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, what be will be described below is variousEmbodiment will refer to corresponding accompanying drawing, and these accompanying drawings constitute a part for embodiment, which describe and realize that this practicality is newThe various embodiments that type may be used.It should be appreciated that it is also possible to use other embodiments, or embodiment enumerated herein is carried outModification structurally and functionally, without departing from scope and spirit of the present utility model.
As shown in figure 1, a kind of power supply adaptor embodiment that can effectively radiate of the utility model offer, including housing 10,The control unit 20 that is arranged in housing 10, the adapter circuit 30 being connected with control unit 20, for monitoring housing in real timeThe temperature sensor 40 of temperature and the radiator 50 for effectively being radiated to the inside of housing 10 in 10；Wherein, control singleThe temperature that member 20 monitors temperature sensor 40 is compared and output control signal control radiator 50 with preset temperature threshold valueBe turned on and off.
The adapter circuit 30 for the power supply adaptor that the utility model can effectively radiate includes being sequentially connected for accessing cityThe EMI filter circuit 301 of electricity, current rectifying and wave filtering circuit 302, isolating transformer 303, output filter circuit 304 and with isolating changeDepressor 303 connected voltage and current monitoring circuit 305.Wherein, the output end of output filter circuit 304 and control unit 20,Temperature sensor 40 and radiator 50 are homogeneously used in conjunction in power supply.Specifically, by output filter circuit 304 to control unit 20,Temperature sensor 40 and radiator 50 are powered, it is preferred that radiator 50 is radiator fan.
The housing 10 for the power supply adaptor that the utility model can effectively radiate is provided with the corresponding surrounding of radiator 50 to be used forThe thermal vias of radiating, housing 10 is the PPS polyphenylene sulfides of high heat conductive insulating or the housing of PA46 nylon, the inner wall surface of housing 10Insulating waterproof layer is also coated with, and then can prevent water droplet from entering adapter to damage to be adapter circuit.
The power supply adaptor that the utility model can effectively radiate uses generation amount of heat in the long-time of adapter circuit 30When, control unit 20 sends control life when the temperature that temperature sensor 40 is detected in housing 10 exceedes preset temperature threshold valueOrder starts radiator 50, and then adapter circuit 30 is radiated, and can be effective by the thermal vias on housing 10Heat is evacuated, heat discharges power supply adaptor finally by the thermal vias on shell 10, and then causes adapter enclosure interiorProblem is controlled in suitable scope, is unlikely to temperature too high.
The radiator for the power supply adaptor that the utility model can effectively radiate can carry out effective dissipate to the heat of generationHair, realizes the high efficiency and heat radiation to adapter, and radiating effect is good, significantly improves the radiating condition of supply convertor, preventsThe temperature of power supply adaptor itself is too high and influences the normal work and use life-span of whole power supply adaptor.
Preferred embodiment of the present utility model is the foregoing is only, those skilled in the art know, do not departing from thisIn the case of the spirit and scope of utility model, various changes or equivalent substitution can be carried out to these features and embodiment.SeparatelyOutside, under teaching of the present utility model, these features and embodiment can be modified to adapt to particular situation and materialWithout departing from spirit and scope of the present utility model.Therefore, the utility model is not by specific embodiment disclosed hereinLimitation, the embodiment fallen with the range of claims hereof belongs to protection domain of the present utility model.
