Description

Cabinet for Electric Device {Cabinet for Electric Device}

This embodiment relates to a cabinet structure of an electronic apparatus used for protecting and effectively installing electric and electronic communication equipment.

In general, panel cabinets that store electricity, passenger, and communication equipments are equipped with various electric equipments in a rack type inside. At least one air outlet is formed on the upper surface or the side wall for discharging the heat generated from the electric components to the outside, and the air inside the cabinet containing the heat is discharged to the outside through the air outlet. As the air flow is more smooth, it is advantageous for the heat discharge. Therefore, it is possible to make the air flow by using a fan or the like, or to form a separate air flow path or the like.

However, in the case of the related art, the air inlet provided in the front part or the like and the fan unit mounted on the upper part are used to flow the outside air into the system to forcibly cool the heat generating parts. However, when the positions of the heat generating parts are arranged on the rear surface of the cabinet, There is a problem that cooling is difficult. That is, in the case of the upper surface provided with the cooling fan unit or in the vicinity of the air inlet where the outside air directly flows, cooling is easy, but relatively cool air can not flow into the rear surface of the cabinet to be. If the heat-generating components can not be sufficiently cooled, the temperature of the rear portion of the heat-generating component may rise above the safe temperature reference, which may cause problems in operation and reliability of the entire system.

1 and 2, the cabinet of the electronic apparatus according to the present embodiment may include a body 10, a duct unit 100, and a fan unit 200.

The body 10 may be formed of a metal material, and may be formed in a box shape by connecting a metal panel to a plurality of frames. A plurality of air intake openings 11 may be formed in the front surface of the body 10. The air intake openings 11 may be formed in various shapes such as a slit shape or a mesh shape as well as a square having a predetermined area. The air inlet 11 may be provided with a filter unit for preventing the inflow of foreign matter, and may be provided with an open-type through-hole.

The duct unit 100 may include a first intake frame 111 having an intake hole 101 and a first exhaust frame 112 having an exhaust hole 150. According to the present embodiment, the intake hole 101 of the duct unit 100 can be disposed on the front surface of the body 10, and the exhaust hole 150 can be disposed on the rear surface side of the body 10 . The construction of the duct unit 100 will be described later in more detail.

The fan unit 200 is disposed on the upper surface of the body 10 to forcibly discharge the air in the internal space of the body to the outside. According to the present embodiment, a plurality of fan units 200 may be provided, but not limited thereto, and one fan unit 200 may be disposed at the center. Alternatively, it may be provided on the side wall or rear wall side of the body 10, or on the bottom side, although not shown.

According to the present embodiment, the duct unit 100 may include the first intake and exhaust frames 111 and 112 as described above.

The first intake frame 111 is formed at an end portion of the intake hole 101. The intake hole 101 may be disposed in the front portion of the body 10. [ However, the present invention is not limited thereto, and the air intake hole 101 can be disposed at any position where external air such as a side wall or a bottom surface of the body 10 can be sucked.

At least one pair of the first intake frames 111 may be provided. As shown in FIG. 2, a pair of the first intake frames 111 having the same shape may be arranged in parallel to each other with a predetermined distance therebetween . The other end of the intake hole 101 may be connected to the first exhaust frame 112.

The first intake frame 111 may have various shapes. For example, they may be formed in a general rectangular frame shape as shown in FIGS. 2 to 4, or in a circular pipe shape as shown in FIGS. 5 to 7. Alternatively, it is also possible to provide a triangular or polygonal frame, though not shown. The shape of the first intake frame 111 may be variously changed depending on the shape of the electric component and other design factors.

The first exhaust frame 112 is provided in a shape corresponding to the first intake frame 111 and connects both ends of the first intake frame 111 to connect the air introduced from the intake hole 101 And can be discharged through the discharge hole 150. For example, if the first intake frame 111 is a square pipe structure, the first exhaust frame 112 may also be provided in a corresponding rectangular pipe structure.

According to the present embodiment, the first intake frame 111 and the first exhaust frame 112 may be vertically connected. Accordingly, it can be formed to have a substantially "C" shape as shown in the figure. However, the present invention is not limited thereto, and it may be a different form according to need. However, since it is necessary to simply configure the flow path to maintain the flow rate of the air passing through the inside of the frame, it is preferable to have a flow path of a straight line or a curved line as much as possible.

1 and 2, the duct units 100 are arranged at different heights, and the first to third intake frames 111 (first and second intake frames) 121) 131 and first to third exhaust frames 112, 122, 132, and each of the frames may have a predetermined height difference. In this case, the plurality of electrical parts are arranged at different heights, and the first to third intake holes 101, 102, and 103 suck the outside air, The heat exchange efficiency can be improved by intensively injecting air to a portion close to the rear and rear wall surfaces.

For example, as shown in FIG. 2, the first to third intake frames 111, 121 and 131 may be arranged to have different heights at regular intervals, (112) 122 and 132 may be arranged to have the same height difference. At this time, the first intake frame 111 and the second intake frame 121 communicate with the first connection duct 141, and the second intake frame 121 and the third intake frame 131 communicate with the second connection duct 141 142). At this time, the first and second connecting ducts 141 and 142 may be provided in the same shape, and a pair of the connecting ducts 141 and 142 may be provided.

3, the duct unit 100 includes only a pair of the first intake frames 111, and the air introduced through the first intake frames 111 And can be transmitted to the first and second exhaust frames 111 and 112 arranged at different heights. In this case, the electric components are installed in two stages, and the air is sucked by sucking the outside air through only the first number of the first intake holes 101 formed in the minimum number.

Alternatively, as in the third embodiment shown in FIG. 4, the duct unit 100 may be constituted by the first and second intake frames 111 and 121, and the first and second suction holes 101 and 102, The heat source of each electric component can be cooled.

Meanwhile, the exhaust hole 150 of the first exhaust frame 112 may have any one of a rectangular shape, a circular shape, a triangular shape, and a polygonal shape.

5, when the first intake frame 111 is circular, the first exhaust frame 112 may also be formed in a circular pipe shape. At this time, the exhaust hole 150 is formed in a rectangular shape So that the air can be introduced. Alternatively, as shown in FIG. 6, the discharge holes 150 may be formed in a circular shape, three of which may be formed at regular intervals, or a plurality of the discharge holes 150 may be closely arranged as shown in FIG.

According to such a configuration, when the air inside the cabinet is forcibly discharged to the outside by the fan unit 200, the inside of the cabinet forms a lower air pressure than the outside, and the first to third suction holes 101 (102) and (103).

Air sucked through the first to third suction holes 101, 102 and 103 is discharged through the discharge hole 150. The discharge hole 150 is formed in the rear surface of the cabinet So that the amount of air flow at this portion can be increased to improve the cooling efficiency according to the heat convection.

In particular, since cool air can be concentratedly supplied directly to the vicinity of the heat source, it is possible to prevent the malfunction of the device due to overheating of the electric component, and it is possible to effectively control the temperature inside the cabinet.

The first to third intake frames 111, 121, 131, and the first to third exhaust frames 112, 122, 132 are connected to each other through the first through third intake frames 121, A separate fan unit may be additionally provided in the inside of the heat exchanger to form forced air convection.

Meanwhile, the duct unit 100 configured as described above may be separately formed from an angle or a pedestal for installing electrical components, but it may also function as an angle pedestal if necessary.

It is also possible to adopt a separate heat insulating means for preventing the temperature of the air sucked on the outer surface of the duct unit 100 from dropping or a double pipe type in which cooling water or the like passes. Since the double pipe structure is a description of a known area, a detailed description thereof will be omitted.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
