Abstract

The utility model relates to a structure of a power supply device, which is composed of a base seat and a cover body, wherein, a plug and an exhaust fan are arranged behind the base seat, the plug is led to connect commercial power, and therefore, the exhaust fan can draw hot air generated in the base and lead the hot air to flow out; the inner surface of the cover body is provided with at least a fan, the fan can suck in outside cold air to directly blow an electronic circuit, and then, the cold air passes through the exhaust fan on the rear of the base seat and is led to be discharged outward, so as to lead the interior and the exterior of the power supply device to form air convection; the plug on the back side of the base seat is connected with a socket and an electronic switch, when the power supply device supplies power to a computer host machine which is in the open state, the socket can simultaneously and externally connect the commercial power to supply power; when the computer host machine is closed, the electronic switch can be actuated via linking, so as to lead the socket to form an open circuit, and simultaneously stop supplying power to outside, in order to lead the power source supply device to further provide the external connection of the electric power and to achieve automatic switchover of an electric outlet mode.

Description

The structure of power supply unit

Technical field

The utility model is relevant for a kind of structure of power supply unit, is meant especially a kind ofly can effectively promote its heat dissipation, has the keying interlock that can be subjected to host computer simultaneously concurrently, and the power supply unit of its external powering mode that automaticallyes switch.

Background technology

Computer technology makes rapid progress, be example wherein with the system computerized device of present Mainstream Packs, the central processing unit that is installed (CPU) adopts Intel Pentium 4 or AMD K7 series no matter be, its speed has all reached the dominant frequency of 2.0GHZ, and CD-ROM drive (CD-R) that its device is some and digital CD-ROM drive (DVD-R) etc., the speed of its running reaches more respectively more than 56 times and 16 times, for satisfying aforementioned central processing unit (CPU) and in order to drive the respectively primary demand of the motor running of this CD-ROM drive, this power supply unit is the power output that must provide higher, in this computer, still need the again keyboard that has of device, built-in modem, network interface card, adapter, digiboard, peripheral equipment such as mouse and loudspeaker, all can obtain power supply from its bus, even some integrated computer, its computer screen, printers etc. also must be supplied with by computer, thereby make the computer power consumption heighten, reached the state that almost can't load, What is more, increase sharply at computer and its peripheral equipment processing speed, the heat that it produced also improves relatively, so be that the more fan of necessary means provides heat radiation (annotate: the power source of fan is still by computer to be obtained), the demand of computer has been unable to supply and has been satisfied to the power supply unit of working standard type (its power output is about 250W) for this reason, and essential its power output that effectively promotes, improving the problem of this power supply unit power output again, the first will be somebody's turn to do heat-generating electronic elements in order to step-down rectifier (transformer for example, commutator etc.) capacity increases; It two is the electronic heating elements that will solve aforementioned step-down rectifier, increases the high-temperature effect that is produced because of capacity; This is to have the dealer that this aforementioned problems is done one oppositely to think deeply for an edge, wherein as shown in Figure 1, is that power supply unit P1, the P2 of two standard types that will be commonly used folded row, and places in the framework by power connector and joint group, to promote its power output; For another shown in Figure 2, be in a hollow housing A, to be provided with two disposal areas, make this two disposal area be installed with for two groups of power supply casing B1, B2, and connect with power output, so with regard to aforementioned person, though can exert oneself for using, no matter but be to use power supply unit P1, P2 or power supply casing B1, B2, all be to utilize the power supply unit that connects two working standard type capacity to reach, except that accounting for if with, the space because of it is bulky, in its when combination, need in addition with connector and circuit parallel connection, and cost also improves more than two times at least, is not inconsistent economic benefit at all; Moreover, with regard to general computer internal layout and layout, there is not sufficient space can supply installing at all, in addition on the technological means with regard to its solution, be not under the space and specification condition of a reciprocity standard, solve to promoting high power and export high temperature and the heat dissipation problem that uses high power capacity electronic heating element to be derived, so its technological means is not brilliant and professional, really do not deal with problems, so the utilance of industry and wish are all not high yet.

Because the prostatitis deficiency, this creator is the improvement of being determined, and through constantly development test, finishes the utility model eventually.
