Embodiment
The present invention is a kind of electronic installation of tool radiator structure.Though following examples illustrate technology of the present invention with the power-supply adapter of tool radiator structure, the electronic installation that can use the technology of the present invention is not limited to power-supply adapter, and any electronic installation that is suitable for following technical characterictic all can be incorporated reference at this.
See also Fig. 2 (a), it is the structural representation of the power-supply adapter of the present invention's first preferred embodiment.Shown in Fig. 2 (a), power supply transfer 20 of the present invention is an ac/dc adapter, converts the required d. c. voltage signal of an electronic product (not icon) running in order to the ac voltage signal with a civil power.Please consult Fig. 2 (a) and Fig. 2 (b) again, as shown in the figure, power-supply adapter 20 of the present invention is combined by body 21, elastic component 22 and insulating component 23.Certainly, above-mentioned elastic component 22 with heat radiation function and insulating component 23 can according to user's design requirement be arranged at power-supply adapter 20 arbitrary side and also can be in order to strengthen radiating effect in many sides setting of power-supply adapter 20.
In addition, elastic component 22 can use to have the material that expands with heat and contract with cold and do not have conductive characteristic and makes, in the embodiment of the invention with rubber blanket as elastic component, and it can present swelling state when being heated, on the contrary the temperature cooling then can be withdrawn.
Wherein, the coefficient of heat conduction of elastic component 22 must be greater than the coefficient of heat conduction of body 21, when the high heat that is produced during because of the running of each electronic building brick in the power-supply adapter 20 causes the temperature of body 21 to raise, elastic component 22 is an expanded by heating and upwards drum is bent, and drive this insulating component 23 together with ground and upwards promote, insulating component 23 is removed from the surface of these perforates 211, and then between body 21 and elastic component 22, produce heat-dissipating space 24 (shown in Fig. 2 (c)), make air be circulated between above-mentioned perforate 211 and the heat-dissipating space 24, so that electronic installation is dispelled the heat, reduce the high heat that each electronic building brick is produced in the body 21 fast when running.
See also Fig. 3 (a) and reach (b), it is the solid and the cross-sectional view of the electronic installation of the present invention's second preferred embodiment.In the present embodiment, elastic component is made of sheet metal 321 and insulating sleeve 322, wherein sheet metal 321 has the high characteristic that expands, and is when power-supply adapter 30 is heated that the rapid expanding drum is bent, can reduce the high heat that each electronic building brick is produced when running in the body 31 at short notice.In addition, insulating sleeve 322 is the structure of a hollow, can make the inside of 322 sockets of part sheet metal and insulating sleeve 321, in order to the situation of avoiding leaking electricity.
When sheet metal 321 will drive insulating sleeve 322 because of temperature overheating expanded by heating drum when bent and insulating component 33 is removed on the surface of above-mentioned perforate 311, and generation heat-dissipating space 34 (shown in Fig. 3 (c)) between body 31 and the elastic component 32, the above-mentioned perforate 311 of body 31 is communicated with the external world, and be able to by the mode of circulation of air between above-mentioned perforate 311 and heat-dissipating space 34, come electronic installation is dispelled the heat.
Otherwise when the temperature of elastic component 32 descended, elastic component 32 drove insulating component 33 withdrawals with the Yin Wendu cooling, makes insulating component 33 be covered in the surface of above-mentioned perforate 311 again, leaks electricity via above-mentioned perforate 311 to prevent body 31.
Certainly, in the present embodiment, elastic component 32 and insulating component 33 equally can according to design requirement be arranged at power-supply adapter 30 arbitrary side and also can be in order to strengthen radiating effect in many sides setting of power-supply adapter 20.And insulating component 33 utilizes rubber material or acryl material made, but not as limit.
See also Fig. 4 (a) again and reach (b), it is the solid and the cross-sectional view of the electronic installation of the present invention's the 3rd preferred embodiment.In this embodiment, radiator structure is arranged at the different dual-side of power-supply adapter 40 respectively, in order to increase the effect of heat radiation.Wherein, insulating component 43 is a paster, it is pasted on the elastic component 42 in the mode of twining, and its position that is pasted on elastic component 42 corresponds to the perforate 411 of body 41, on the surface that is covered in these perforates 411, in order to prevent body 41 situation of electric leakage takes place via above-mentioned perforate 411.
In addition, the two ends of elastic component 42 can embed the inside of bodies 41 by various fixed forms, for example fix, adhere to or mode such as locking.When the temperature of body 41 raises, because the inside of body 41 is fixed at the two ends of elastic component 42, therefore the central portion branch of elastic component 42 expands toward specific direction, be that elastic component 42 can be a bowed state by the state balloon song on plane, and drive insulating component 43 together with ground and on the surface of above-mentioned perforate 411, remove, make and produce heat-dissipating space 44 (shown in Fig. 4 (c)) between body 41 and the elastic component 42, make air be circulated between above-mentioned perforate 411 and the heat-dissipating space 44, so that electronic installation is dispelled the heat, reduce the high heat that each electronic building brick is produced in the body 41 fast when running.
See also Fig. 5 (a) and reach (b), it is the structural representation of the power-supply adapter of tool radiator structure of the present invention as for a surface.As shown in the figure, when the temperature of power-supply adapter 50 is not overheated, do not place on the surface 55 with the power-supply adapter of known technology smooth with having difference, for example: desktop or ground, when power-supply adapter 50 comes into operation and temperature when raising gradually, elastic component 52 will begin to expand, and together with ground with the insulating component 53 outward bulge songs that originally are covered in the perforate, and make between body 51 and the elastic component 52 and to form heat-dissipating space 54, because the both sides up and down of body 51 all have elastic component 52 (shown in Fig. 5 (c)), just the air in the perforate of the both sides up and down of body 51 and the external world can produce convection effect.Thus, by the circulation of air, the heat that power-supply adapter 50 is produced because of running just can be taken away to loose by air gradually and remove, and so just can reach the function of heat radiation, and then avoid power-supply adapter 50 because of the too high and issuable every shortcoming of temperature.
In sum, the electronic installation of tool radiator structure of the present invention, its when the electronic installation temperature improves the elastic component by having the characteristic of expanding with heat and contract with cold together with ground with the insulating component outward bulge song that originally is covered in the perforate, make electronic installation can utilize the formed heat-dissipating space hot gas discharge external world that it is inner between body and the elastic component, the height that is produced when turning round in order to each electronic building brick in the quick reduction body is warm.And then the power-supply adapter that solves known technology will produce fault because of overheated situation, or cause the failure rate of electronic product to increase because of electricity is unexpected or the life-span such as shortens at shortcoming.
The present invention can carry out various modifications by those of ordinary skill in the art, but neither disengaging the application's claim.
