Embodiment
The present invention is a kind of electronic installation with Natural Heat Convection structure.Though following examples illustrate technology of the present invention with the power supply unit (Power Supply) that is applied to removable computer (Desknote), yet the electronic installation that can use this case technology has more than the power supply unit that is limited to removable computer (Desknote), any electronic installation that is suitable for following technology, for example traditional power supply unit, power-supply adapter, charger, transformer etc. all can be incorporated reference at this.
Power supply unit with Natural Heat Convection structure of the present invention mainly has plate, a first circuit board and at least one support component that a shell structure, has first hole.In this case embodiment, power supply unit with Natural Heat Convection structure also comprises input element and output element, wherein input element can be plug, socket and power line etc. one of them, and output element according to input element also can be selected from with changing plug, socket and power line etc. one of them.For convenience of description, following examples will be input element (that is socket can an external power-line plug import civil power) with the socket, power line is that output element (that is can be electrically connected to an information equipment by power line, removable computer (Desknote) for example), to describe technology of the present invention more in detail.
Please cooperate and consult Fig. 2 and Fig. 3, wherein Fig. 2 is the schematic diagram of preferred embodiment surface structure of the present invention, and Fig. 3 is the schematic diagram of preferred embodiment internal structure shown in Figure 2.As shown in Figures 2 and 3, the present invention's the electronic installation with Natural Heat Convection structure comprises that at least a shell structure 21, has the plate of first hole 22, a first circuit board 23 and at least one support component 24.Wherein, be respectively equipped with corresponding opening on the end face of shell structure 21 and the bottom surface, this plate places the inside of this shell structure 21, first hole 22 runs through this plate and is connected with opening on the bottom surface 212 with the end face 211 of shell structure 21, first circuit board 23 is arranged at shell structure 21 inside, and straight parallel on the spot places a side of the plate with first hole 22 in fact, and support component 24 places the bottom surface 212 of shell structure 21, and support component 24 has certain height h, wherein certain height h must cooperate the size of electronic installation and change, minimum height is approximately more than or equal to 3mm, uses and put to form one between the surface of electronic installation the space that produces natural convection air can be provided.
Usually, electronic installation of the present invention is arranged on the desktop or on the ground, when electronic installation uses, the temperature of the first circuit board 23 of shell structure 21 inside can raise gradually, mode by conduction or radiation, the heat energy that first circuit board 23 is produced just can be passed to the case surface of electronic installation gradually, and at this moment, near the air the electronic installation bottom surface 212 just can be subjected to the influence of first circuit board 23 high temperature and heat and temperature begins to raise gradually.Because, the certain height h that the support component 24 of shell structure 21 bottom surfaces 212 is had can make to have specific range between the shell structure 21 of electronic installation and desktop of being put or ground, therefore near the air Yin Wendu shell structure 21 bottom surfaces 212 raises, after density diminishes, the air that is heated just can begin upwards to flow, then first hole 22 that can upwards run through via shell structure 21 bottom surfaces 212 and upwards loss, cold air around making is filled vacancies in the proper order the hot-air that upwards flows, one radiating airflow that makes progress of mobile formation by air like this, to get rid of electronic installation because of using the heat that is produced, and, will produce higher thermal convection effect on the electronic installation surface, so easier heat with the surface is taken away, and then reduce the bulk temperature of electronic installation, reach the effect of heat radiation.The more important thing is,, make area of dissipation be increased, so more can further strengthen radiating effect because first hole 22 for running through structure, also can further increase the whole surface area of electronic installation.Certainly, in an embodiment of the present invention, shell structure 21 inside also can comprise a second circuit board (not shown), its also can be parallel and relative first circuit board 23 place the opposite side of plate with first hole 22, when power supply unit was in user mode, the radiating airflow that is produced in first hole 22 can be taken away the heat that first circuit board 23 and second circuit board (not shown) are produced simultaneously.
In addition, for avoiding when the careless overturning of power supply unit, first hole 22 can't provide the situation in natural convection air space, electronic installation of the present invention also can comprise one second hole 25, it can run through the sidewall 213 of shell structure 21 accordingly, 214, and it is identical and parallel in fact with the direction of first hole 22, thus, when electronic installation of the present invention collapses or tilts, support component 24 so just can avoid electronic installation to take place because of the problem that careless overturning causes dispelling the heat from these shell structure sidewall 213 outward extending spaces that natural convection air can be provided too greater than the specific width of 3mm in fact.
Certainly, configurable circuit board quantity and indefinite in the electronic installation of the present invention, and the quantity of hole, size and shape also do not limit.Usually, in order to improve radiating efficiency, first hole with and/or the optimum position of the second hole arrangement be located at the centre position of electronics, so that first hole with and/or second hole equal in fact to the distance of the arbitrary periphery of shell structure, so can make radiating efficiency comparatively average, the position near internal circuit board or big pyrotoxin also is preferable selection certainly.In general, for the convenience on the manufacturing process, plate with first hole with and/or second hole mostly and the shell structure of electronic installation one-body molded, and cooperate circuit board mostly in shape and be designed to long strip type, decide locus on electronic installation internal circuit board configuration, first hole with and/or second hole also can be other different shape.
In sum, electronic installation of the present invention is owing to have first hole that runs through shell structure, with and/or when the electronic installation overturning, second hole in free convection space can be provided equally, and the electronic installation bottom has support component so that certain height h to be provided, the air that makes electronic installation bottom be heated be able to along first hole with and/or the loss that makes progress of second hole, and by around cold air fill vacancies in the proper order after, the radiating airflow that can form one circulation to be strengthening the surface heat convection effects of electronic installation, and first hole that runs through with and/or the area that increased of second hole also can increase total area of dissipation of electronic installation integral body.Therefore, can improve the shortcoming that present electronic installation heat radiation is difficult for greatly, increase the radiating efficiency of electronic installation.In addition, on making, the shell structure of this electronic installation can with first hole with and/or second hole one-body molded, and be unlikely to increase manufacturing cost and time cost.So the present invention has industrial value.
