Abstract
The utility model relates to a computer power supply, which employs the standard ATX12V computer power supply electrical specification, wherein on the +5VSB circuit of the standard ATX12V computer power supply, the utility model divides two paths of electric voltage from an elementary transformer, one path thereof is transformed into +5VSB output through a control circuit, and the utility model adds a set of control and protection circuit to transform the other path into +12VSB output. The +12VSB output is connected with the computer component in the computer through output lines and supplies the power for a LCD displayer, a DVD playing device, a sound box and so on. In the main power supply closing situation, the utility model keeps the +12VSB output and the +5VSB output existed at the same time and supplies the power for part of the computer equipments. One side of the power supply casing is equipped with two fans, and the other side of the power supply casing or the other side and the back part of the casing all opened with radiating holes. The utility model provides a group of electric voltage output independent of the main power supply, realizes the function of the multimedia under the closing situation, effectively utilizes the space and increases the wind flow quantity, and can more effectively dissipate the heat, widely applicable for the personal computer.
Description
Technical field: the present invention relates to a kind of machine element, relate in particular to a kind of computer power supply.
Background technology: in order to adapt to the trend of current PC main frame miniaturization, the ATX power supply of standard can not satisfy the requirement of minicomputer system to high-power, small size and high efficiency and heat radiation.
Along with the rapid growth of PC performance, the consumer is more and more to the demand of multimedia recreation aspect, how to allow PC bring into play usefulness as much as possible, and becoming the one family multimedia hub is the trend of present PC development.In order to comply with this trend, must on PC, increase many additional functions, but the ATX power supply of standard only provides one tunnel+5VSB electric current, because the restriction of ATX power supply itself, all functions all will can realize under the situation of main frame start.
Miniature Power Unit in the past all exists a unavoidable problem, heat dissipation problem.Small-sized cabinet inner space is comparatively crowded, is not easy to form effective air channel, and the fan of Miniature Power Unit is little, and ventilation is little, for case radiation brings problem.
Summary of the invention:
The purpose of this utility model provides a kind of voltage output that is independent of primary power that has, and is the part parts power supply of system, realizes the computer power supply of multimedia function under the situation of not starting shooting.
The utility model purpose also is to provide a kind of computer power supply with good radiating effect.
Computer power supply of the present utility model adopts standard A TX12V computer power supply electrical specification, be provided be independent of primary power+12VSB standby current output circuit.
The utility model extrudes two-way voltage from the primary transformers branch on standard A TX12V computer power supply+5VSB circuit, wherein one tunnel process control circuit is converted to+5VSB output, sets up a cover and controls and holding circuit, is converted to+12VSB output other one the tunnel.
Computer power supply of the present utility model is provided with two fans in power supply casing one side.All offer louvre at power supply casing opposite side or opposite side and casing rear portion.Used fan is the 8CM fan.
The utility model provides one group of voltage output that is independent of primary power, and the part parts power supply for system realizes multimedia function under the situation of not starting shooting.
The utility model is considered the inner structure that adapts to cabinet, structure is elongated, and place two fans in the side, has effectively utilized the space, has increased wind flow.And increased louvre at opposite side and rear portion, can more effectively dispel the heat.

Embodiment:
The utility model designs according to the ATX12V standard on electrical specification; as shown in Figure 3, Figure 4; on original+5VSB circuit, make improvements; divide extrusion two-way voltage from primary transformers; wherein one tunnel process control circuit is converted to+5VSB output; increase by a cover control and a holding circuit, be converted to+12VSB output other one the tunnel.+ 12VSB electric current is connected with the equipment of main frame inside in main frame inside by power supply output line, is its power supply, peak power output 72W.As shown in Figure 2.Like this, can be under the situation that primary power cuts out, part parts (such as display, DVD playing device, the audio amplifier etc.) power supply for main frame realizes some multimedia functions.
As shown in Figure 1, it is system radiating that the utility model adopts the fan of two 8cm, is guaranteeing the reduced volume of trying one's best under enough heat-sinking capability prerequisites.Structurally, all opened louvre, provide good ventilation condition to system radiating in the side and the back of casing.
