Description
Technical field
The present invention is a kind of power supply device with electromagnetic compatibility function heat dissipating structure, and this device can provide a kind of have electromagnetic compatibility and heat sinking function, and can conversion electric power.
Background technology
Power supply device, for example: power supply unit or power supply adaptor etc., it has the galvanic function that the alternating current that general supply socket is provided is transformed into required by electronic product, so power supply device is used in various electronic products widely.
Existing power supply device please cooperate with reference to shown in Figure 3, and it has a circuit board 30, is provided with some electronic components 31 in a side of circuit board 30.On portions of electronics part 31, baffle 33 can be set, wherein electronic component 31 coats within the baffle 33, be mainly and cover electromagnetic interference, in addition, between electronic component 31 and baffle 33, be provided with heat conduction material 32, utilize heat conduction that heat conduction material 32 produces electronic component 31 to baffle 33, avoid because of baffle 33 when disturbing electromagnetic wave, the heat that electronic component 31 is produced can't derive, and the life-span of minimizing electronic component 31, between baffle 33 and circuit board 30, be provided with liner 34, one housings with aforementioned circuit board 30 in addition, electronic component 31 is coated in it with baffle 33.
Comprehensive above institute says, though existing baffle 33 provides the effect of heat sinking function and compatible electromagnetic wave, but baffle 33 main purposes are compatible electromagnetic wave, because baffle 33 is whole coatings, must consider the heat radiation of electronic component 31, therefore the heat conduction of heat conduction material 32 is set, the high heat conduction that electronic component 31 can be produced is to baffle 33 places, reach the effect of heat radiation by this, so baffle 33 can not be directly with electronic component 31 coolings, therefore its radiating effect is limited, and this device is each coating, time-consuming taking a lot of work on handling.
Summary of the invention
In view of this present inventor is actively to set about research and development, in the hope of a kind of power supply device with the compatible function heat dissipating structure of electromagnetic compatibility with electromagnetic compatibility and heat sinking function can be provided, through constantly experiment and effort, develops the present invention finally.
Main goal of the invention of the present invention is to provide a kind of have electromagnetic compatibility and heat sinking function, and the device of energy conversion electric power.
In order to reach aforementioned goal of the invention, technological means of the present invention is to provide a kind of power supply device with electromagnetic compatibility function heat dissipating structure, and it has a circuit board, is provided with electronic component in a side of circuit board;
One catch, it is located at the another side of circuit board, and the side of catch is connected with the fin through bending, and circuit board is between fin, and at least one electronic component and fin fit tightly.
When electronic component will be transformed into direct current from the alternating current of general socket, it can generate electromagnetic waves and high temperature, the compatible electromagnetic wave of catch, make it can't leak to the outside of power supply device with electromagnetic compatibility function heat dissipating structure, and the fin of fitting mutually with electronic component, the high temperature that electronic component produced can be lowered the temperature, and fin also can reach high temperature the catch place, and making catch also have the effect of heat radiation, electronic component can remain in suitable working temperature by this.
Therefore the present invention can reach compatible electromagnetism and have radiating effect concurrently, and electronic component directly can be dispelled the heat for full wafer extends, so radiating effect of the present invention is preferable, and assembles more or less freely.

Embodiment
The present invention is a kind of power supply device with electromagnetic compatibility function heat dissipating structure, this power supply device can be power supply unit or power supply adaptor, please cooperate with reference to Figure 1 and Figure 2, it has a circuit board 10, one side of circuit board 10 is provided with electronic component 20, and this electronic component 20 can be power transistor 21, transformation coil 22, several capacitors 23 and a socket 24;
One catch 12, it is located at the another side of circuit board 10, and the dual-side of catch 12 is connected with the fin 121 once bending respectively, and fin 121 closely pastes with at least one electronic component 20, and circuit board 10 is between two fin 121;
One insulator 11, it is located between circuit board 10 and the catch 12;
At least one intermediate plate 13, it is clamped at least one electronic component 20 and fin 121 places, and this electronic component 20 is more closely pasted with fin 121, and can strengthen the heat sinking function of fin 121, in present embodiment, this electronic component 20 is a power transistor 21.
When reality is used; when being used as the power supply unit use as power supply device; but on-line equipment is in the inside of electronic product; and when being used as the power supply matching device and using as power supply device; need aforesaid each member is coated on a housing 25 inside, can give the suitable protection of each member and attractive in appearance by this.
When power supply device interconnects with a general supply socket and an electronic product respectively, electronic component 20 can convert the alternating current from supply socket to the direct current of required by electronic product, because electronic component 20 can produce electromagnetic wave is arranged in the conversion electric power process, influence the running of other electronic product or human body is produced unpredictable injury for fear of electromagnetic wave, so pass through the compatible of catch 12, make its electromagnetic wave can't leak to the outside of power supply device, and catch 12 is made by metal, therefore the function of insulator 11 is to prevent that each solder joint of electronic component 20 and catch 12 are in contact with one another, and guarantees electronic component 20 normal operations by this.
And electronic component 20 is in the conversion electric power process, its power transistor 21 can produce the highest working temperature than all the other electronic components 20, by fitting tightly of itself and fin 121, and make the high temperature of power transistor 21 can conduct to fin 121 places, make power transistor 21 fully to dispel the heat by this, in addition, the high temperature on the fin 121 also can conduct to catch 12 places, and catch 12 also can dispel the heat.
So the high heat conduction that is produced when electronic component 20 is to fin 121, when high heat also can conduct to catch 12 places, and reach the effect of heat radiation by catch 12 and fin 121, and catch 12 compatible electromagnetic waves, make its outside that can't leak to power supply device, therefore have the convenience that it uses.
