Assembly device for power supplies

An assembly device for a power supply is composed of a rectangular case which is provided with a transversal spacer grid in a horizontal direction, with an upper spacer grid and a lower spacer grid being vertically installed above and below the transversal spacer grid, to divide the rectangular case into four rectangular positioning holes; and four rectangular power supplies which are inserted and fitted into the four rectangular positioning holes respectively, such that when the four power supplies start, four fans at their front parts can be activated, thereby allowing air inside and outside the rectangular case to be able to flow uniformly.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to an assembly device for an power supply, and more particularly to an assembly device wherein when four power supplies which are emplaced in a rectangular case start, air can flow in the rectangular case with a superior mobility and uniformity.

(b) Description of the Prior Art

It is known that a conventional power supply is installed at a side of a computer casing; therefore, when the power supply starts, air which is caused by a rotation of an interior fan will not flow with a good uniformity in the computer casing, and an air permeability of the computer casing is not sufficient, which causes an inferior flow and circulation of the air within an interior of the computer casing, thereby further affecting a heat dissipating effect of internal electronic parts.

SUMMARY OF THE INVENTION

The primary object of present invention is to provide an assembly device for a power, supply such that four power supplies can be equally assembled and fitted into a rectangular case, and when the power supplies start, the air can be uniformly flowing within a space of the rectangular case and the power supplies, while the effect of permeability in interchanging with air outside of the rectangular case can be increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring toFIG. 1andFIG. 2, the present invention is to provide an assembly device for a power supply, including a rectangular case10which is provided with transversal spacer grid12in a horizontal direction, with an upper spacer grid14and a lower spacer grid16being vertically located above and below the transversal spacer grid12respectively, to divide the rectangular case10into four rectangular positioning holes15,17,18,19; and four rectangular power supplies20which are inserted into the four rectangular positioning holes15,17,18,19respectively, such that when the four power supplies20start, four fans22at their front parts (as shown inFIG. 3) can be activated to achieve a uniform flow of air inside and outside the rectangular case10.

As shown inFIG. 1, two rectangular through-holes121are located in middles of the transversal spacer grid12, a back surface of the rectangular case10is provided with meshes101, a top surface of the rectangular case10is provided with meshes102, a bottom surface of the rectangular case10is provided with meshes103, and two side surfaces of the rectangular case10are provided with through-holes104, in order to facilitate the air to access the internal space of rectangular case10through the meshes101,102,103, and the through-holes104,121.

The upper and lower spacer grids14,16are provided with through-holes141,161to provide for a circulation of the air between the neighboring positioning holes15,17,18,19.

As shown inFIG. 3, for each power supply20, a peripheral wall of its case is provided with meshes25, and an outlet end of its fan22is positioned at an outlet end of the positioning hole15,17,18,19.

Referring toFIG. 1andFIG. 2, a rectangular case10is equally divided into four rectangular positioning holes15,17,18,19with an identical shape and an identical size, by upper and lower spacer grids14,16. Four rectangular power supplies20can be exactly inserted into the four positioning holes15,17,18,19, and air outlet openings or air suction openings of their fans22are all positioned at outlet ends of the positioning holes15,17,18,19. As shown inFIG. 2andFIG. 3, when the four power supplies20start simultaneously, the four fans22are activated to proceed with air suction (or air discharging). As a peripheral wall of the power supply20is provided with meshes25, the air inside the rectangular case10will be flowing out towards the air outlet openings of fans22along the meshes25. Referring toFIG. 1andFIG. 2, as the rectangular case10is provided with meshes101,102,103, and through-holes104,121, the air inside the rectangular case10is connected with the air outside the rectangular case10. By a design that every one of the four power supplies20is interconnected with each other by the through-holes141,161and121, when the four power supplies20are equally allocated and positioned into the rectangular case10, and the fans22of four power supplies20are rotating to perform the air discharging (or air suction), a convection is caused between the air inside the four positioning holes15,17,18,19within the rectangular case10and the air inside the four power supplies20, through the through-holes141,161,121, with an extremely good uniformity and permeability of circulation.

Referring toFIGS. 3 to 5, a U-shape upper lid30can be covered on a top of the rectangular case10, and at least more than one insertion-hole32is formed between the upper lid30and a top panel of the rectangular case10to provide for an insertion of at least more than one computer module40(or server module). A U-shape lower lid50can be covered on a bottom of the rectangular case10, and at least more than one insertion-hole52is formed between the lower lid50and a bottom panel of the rectangular case10, to provide for an insertion of at least more than one computer module40, server module, or other expansion module. At this time, air (as shown by an arrow sign inFIG. 5), in an internal space of the rectangular case10can be flowing on a peripheral surface of the computer module40through the meshes101,102,103, thereby achieving a purpose of uniformly dissipating heat from a plurality of computer modules40. The design of through-holes104can enable a circulation and permeability between the neighboring power supplies20, and can allow a human finger to easily grab for facilitating a carrying of the entire rectangular case10. In addition, the design of through-holes141,161is to increase the air circulation between the neighboring left and right power supplies20, whereas the design of through-holes121is to increase the air circulation between the neighboring top and bottom power supplies20.

Accordingly, in the present invention, four power supplies20are equally inserted into four positioning holes15,17,18,19of equal size of the case10, so as to improve the circulation of air inside and outside the entire case10, and the uniformity of air flowing inside the case10. In addition, the effect of uniformly dissipating heat caused by the power supplies20and the computer modules40which are inserted into the upper and lower insertion-holes32,52of the case10can be improved.
