Abstract
The utility model relates to a power supplier with improved structure and function, in particular to a power supplier which has an upper cover and a seat in aluminum extrusion type corrugated structure, and two fans at the front and back of the power supplier are respectively provided with a rotation speed controller. By increasing the surface area of a casing, the utility model enhances the heat radiation. Based on the principle of front absorbing and back drawing by the two fans, the utility model quickly exhausts the high temperature heat generated by high speed operation in the computer out of the computer, so as to effectively reduce the temperature in the computer and promise no halted system during long time running of the computer; furthermore, the rotation speed controller for each fan aims at adjusting the rotation speed of the fans according to needs, so as to achieve the computer operation environment without noise.
Description
Technical field
The utility model relates to a kind of power supply unit, and particularly a kind of noiselessness, convection effect are strong, rapid heat dissipation, guarantee that computer can operate for a long time and the computer power supply unit that never crashes.
Background technology
The power supply unit that computer is used is installed in the main frame, and because of a large amount of electronic components are wherein arranged, during work, caloric value is big, if heat can not in time be discharged, just computer has the possibility of deadlock, concerning the user, is likely a kind of phenomenon of murther like this.Thereby improve the heat dispersion of power supply unit, just become people in the industry's a research topic.Used power supply unit is made up of base 21 and loam cake 23 with smooth surface as shown in Figure 1 in the located by prior art, and its louvre 20 is generally the punching press blowhole.Because of its inside only contains a fan and louvre is the non-open type structure, so still inadequate because of the high hot discharge that the long-time running of computer produces to inside.
Summary of the invention
The purpose of this utility model provides that a kind of noiselessness, convection effect are strong, rapid heat dissipation, guarantee the long-time running of computer and the computer power supply unit that never crashes.
The power supply unit that reaches described in the utility model, comprise loam cake, base, header board, back plate, electronic component, aft-fan and aft-fan radiator-grid, electronic component places on the base, be characterized in that described loam cake and base are respectively the one-body molded body of aluminium extruded type, there are the outstanding lines of many groups to strengthen heat radiation on its surface, also are installed with an external radiator fan and radiator-grid to add the convection effect of air blast in front plane surface to increase surface area; Other is polyphone one variable resistor on the fan loop, thereby forms a rotation speed of the fan controller.Wherein said radiator-grid is open ring channel structures; On the plate of back, be provided with the adjustment knob of rotation speed of the fan controller.
The utility model has mainly improved the cooling system of power supply unit, be about to advancing of fan airstream, outlet is improved to open radiator-grid, add a cover radiator fan and a radiator-grid forwardly, after making the air intake fan suction of air-flow by the place ahead, cooperate the ventilating fan at rear that thermal current is extracted out again, connect variable resistor on the fan circuit in power supply unit in addition and constitute the rotation speed of the fan controller, with generally commonly use product and compare, shell of the present utility model is that aluminium extruded type is one-body molded, surface area is bigger, heat radiation is very fast, in conjunction with coolant puller and puser fan and open radiator-grid, so under convection effect and the guiding of expedite air-flow, reach noiselessness of the present utility model, the power supply unit of Si Jiing never.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figures 2 and 3, the utility model mainly by loam cake 1, base 2, header board 3, back plate 4, etc. form a case structure.Tipping has electronic component 10,11 in this casing, and power line 14 stretches out from header board 3, is used for to the host computer power supply, and as shown in Figure 5, back plate 4 is provided with power supply input female seat 16 and mains switch 17 and fan radiator-grid 9.Improvement of the present utility model partly mainly is its radiator structure.Referring to accompanying drawing, loam cake 1 and base 4 are respectively the one-body molded body of aluminium extruded type, and its surface has the outstanding fold of many groups to strengthen heat radiation to increase surface area.On header board, offer an airflow inlet 6, its the place ahead sets firmly external air intake fan 13 with corresponding with the ventilating fan 8 at plate place, back and add the convection effect of air blast, when fan work, as shown in Figure 6, air stream A sucks from air intake fan 13, flow through the power supply unit box house, carry heat that wherein electronic component distributed and discharge casings and reach the effect of heat radiation from ventilating fan 8.For heat radiation better, the designed radiator-grid that matches with fan of the utility model is changed the punching hole structure of commonly using, and adopt the open ring channel structures that meets the air fluid mechanics principle, make the resistance of air-flow intake and exhaust reduce to minimum, and make runner more unobstructed.In order to satisfy user's different needs, polyphone one variable resistor 15 forms a rotation speed of the fan controller on the fan loop, and it is adjusted knob 18 and is placed on the plate 4 of back, can regulated at will rotation speed of the fan and air quantity of fan by this knob user, reach noiseless environment of operation.
Via the said structure assembly, the utility model has reached really that noiselessness, convection effect are strong, rapid heat dissipation, guarantee that computer can operate for a long time and never crash.
The foregoing description does not only limit this practicality with novel in order to explanation, and all any changes of being done within the scope of the claims all should belong to category of the present utility model.
