Description

Fluid purification apparatus and power device including the same}

The present invention relates to a fluid purification device and a power device including the same, and more specifically, to a fluid purification device capable of pre-removing dust mixed in a fluid for cooling and a power device including the same.

Power devices refer to devices that can convert and transmit power by being connected to external power sources and loads. Power devices can receive power from an external power source, boost or step down the power, and transmit it to an external load.

In order to perform the above functions, various electrical devices are mounted inside the power device. As mounted electrical devices operate, heat is generated inside the power equipment. If the generated heat stays inside the power device, there is a possibility that the electrical devices may be thermally damaged.

Accordingly, general power equipment is equipped with components for cooling mounted electrical devices. As an example, a power device can cool mounted electrical devices in the form of air cooling using external air.

However, the outside air may contain various foreign substances such as dust and dirt. If external air flows into the power equipment without a separate filtration process, there is a possibility that the installed electrical devices may be damaged by foreign substances mixed with the external air for air cooling.

To prevent this, a filter is provided at the part where the power device communicates with the outside. The filter is configured to filter incoming external air and filter out foreign substances mixed in the external air.

As the use of power equipment progresses, filters accumulate significant amounts of debris. In the above case, it is difficult for the process of introducing external air to proceed smoothly, and the reliability of the filtration process may also decrease. Furthermore, the replacement cycle of the filter may be shortened, increasing the time and cost required to operate the power device.

Specifically, a cabinet having modules with a thermosiphon cooler arrangement capable of guiding the flow of incoming cooling air using a separate first aperture to receive the stream of cooling air is disclosed.

However, the cabinet disclosed in the prior literature only provides a method for guiding the flow of air for cooling, but does not provide a method for filtering foreign substances mixed in the air.

Korean Patent Document No. 10-0896777 discloses a multiple power supply device with improved mountability. Specifically, a multi-power supply device equipped with a separate cooling fan and capable of introducing cooling air to cool the power device is disclosed.

However, the multiple power supply device proposed in the preceding literature also only provides a method for introducing cooling air into the interior, but does not provide a method for filtering foreign substances mixed in the cooling air.

A vortex hollow 334 is formed inside the neck 332 that extends and penetrates the inside of the base 331, so that fluid from which dust, etc. are separated can flow into the second frame space 222.

Neck 332 is located adjacent to dust outlet 316. In the illustrated embodiment, the neck 332 is located above the dust discharge unit 316, so that dust separated from the fluid can be discharged into the first frame space 212 through the dust discharge unit 316. .

(2) Description of the flow of fluid formed inside the fluid purification device 40 according to an embodiment of the present invention

The fluid purification device 40 according to an embodiment of the present invention can form the flow of incoming external fluid into a vortex shape through the above-described configuration. The fluid flowing into the fluid purification device 40 flows in a vortex form, and mixed dust, etc. can be removed by centrifugation.

The fluid flowing into the fluid purification device 40 flows as described above, and after dust, etc. are separated, it may flow into the interior of the housing 10 through the filter member 20. That is, the fluid for cooling the components of the power device 1 is introduced into the housing 10 after going through at least two filtration processes.

Additionally, as the fluid flows in a vortex shape, the fluid may pass through the filter member 20 after large-sized dust, etc. are removed by centrifugation. Accordingly, the filter member 20 is prevented from being clogged by large-sized dust, etc., and the filtration efficiency and durability of the filter member 20 can be increased.

Hereinafter, with reference to FIGS. 17 to 19, the flow of fluid formed inside the fluid purification device 40 according to an embodiment of the present invention and the process by which dust mixed in the fluid are separated accordingly will be described in detail.

The term "first flow (F1)" used in the following description refers to the direction toward the second cover 120 among the flow of fluid formed in the body hollow 313, that is, toward the rear side in the illustrated embodiment. It means ongoing flow. The first flow F1 is formed in the body hollow 313 and is formed outside the second vortex forming member 330.

The term "second flow (F2)" used in the following description refers to the direction opposite to the second cover 120, that is, the front side in the illustrated embodiment, among the flow of fluid formed in the body hollow 313. It means a flow that progresses towards. The second flow F2 is also formed in the body hollow 313, and is formed outside the second vortex forming member 330.

At this time, it will be understood that the first flow (F1) corresponds to the relatively upstream side of the fluid flow, and the second flow (F2) corresponds to the relatively downstream side of the fluid flow.

In addition, the term "dust flow (FD)" used in the following description refers to the flow of dust, etc., mixed in a fluid and separated from the fluid by centrifugation by the flow of the fluid.

Referring to Figure 17, a partially cut away perspective view of a fluid purification device 40 according to an embodiment of the present invention is shown. In the illustrated embodiment, the front end of the purification module 300 communicates with the outside, allowing external fluid to flow into the purification module 300. The rear end of the purification module 300 is in communication with the second frame space 222, so that fluid from which dust, etc. are separated can flow into the second frame space 222.

At this time, since the purification module 300 communicates only with the first frame space 212 and the second frame space 222, the fluid flowing into the purification module 300 does not leak out to the outside.

18 to 19, the flow process of the fluid formed inside the fluid purification device 40 according to an embodiment of the present invention is shown.

First, external fluid flows into the body hollow 313 through the front end of the purification module 300. At this time, a plurality of purification modules 300 are provided and disposed at different positions, and external fluid flows into the plurality of body cavities 313 formed inside the plurality of purification modules 300, respectively.

At this time, the external fluid passes through the first vortex forming member 320 located adjacent to the front end of the purification module 300 and then flows into the body hollow 313. Accordingly, the first flow F1 is formed as a vortex-shaped vortex and flows in the body hollow 313. At this time, it will be understood that the direction in which the first flow F1 progresses is from the first vortex forming member 320 to the second vortex forming member 330.

As the first flow F1 is formed as a vortex-shaped vortex, a centrifugal force is generated in the fluid in a direction radially outward, that is, toward the inner circumference of the body 312. Accordingly, particles with a relatively large mass, that is, relatively large-sized dust, etc., are moved radially outward.

The fluid that reaches the second vortex forming member 330 collides with the second cover 120 and then flows back toward the first vortex forming member 320. At this time, due to the shape of the second vortex forming member 330, the second flow F2 is also formed as a vortex-shaped vortex. Accordingly, a centrifugal force in the direction toward the inner circumference of the body 312 is generated in the fluid, and dust, etc. is further moved radially outward.

A dust discharge portion 316 is formed through the outer circumference of the body 311 and the inner circumference of the body 312 to communicate with the body hollow 313 and the first frame space 212. In one embodiment, the dust discharge portion 316 may be formed on the lower side of the body portion 310. Accordingly, dust separated from the fluid passes through the dust discharge unit 316 and is discharged into the first frame space 212.

That is, the dust flow FD extends from the radial outside of the body hollow 313 to the first frame space 212 through the dust discharge portion 316.

Meanwhile, the second flow F2 extends toward the first vortex forming member 320 along the neck 332 of the second vortex forming member 330, toward the front side in the illustrated embodiment. The second flow F2 extending to the front end of the neck 332 flows into the open vortex hollow 334. The fluid flowing into the vortex hollow 334 flows into the second frame space 222 connected to the vortex hollow 334.

Thereafter, the fluid passes through the filter member 20 and is filtered again, and then flows into the internal space of the housing 10 through the blowing fan 30 to cool the components of the power device 1. It will be understood that in the above process, the blowing fan 30 may be operated to provide conveying force to the external fluid.

The power device 1 according to the embodiment of the present invention described above can filter the fluid at least twice, including centrifugation by the fluid purification device 40 and filtration by the filter member 20.

Accordingly, components accommodated inside the housing 10 are not damaged by dust mixed in the cooling fluid. Furthermore, since the filter member 20 is configured to filter relatively small-sized dust, etc., clogging of the filter member 20 can be prevented.

5. Description of the coupling relationship between the fluid purification device 40 and the housing 10 according to an embodiment of the present invention

In the embodiment shown in (b) of FIG. 20, the fluid purification device 40 is rotated relative to the housing 10. In this state, the filter member 20 is exposed to the outside and can be removed from the fluid purification device 40. That is, the above state is a state in which replacement or maintenance work on components such as the filter member 20 can be performed.

In this state, the engaging member 235 is removed from the engaging protrusion 15. In one embodiment, as described above, the coupling member 235 can be separated from the coupling protrusion 15 by applying an external force.

Meanwhile, the hinge member 233 is maintained rotatably coupled to the support protrusion 14 by the shaft member 234. As the upper side of the fluid purification device 40 is separated from the housing 10 by removing the coupling member 235, the fluid purification device 40 is rotated about the shaft member 234 and spaced apart from the housing 10. It can be. In the illustrated embodiment, the fluid purification device 40 may be rotated counterclockwise to be spaced apart from the housing 10 .

At this time, the rotation radius of the fluid purification device 40 may be limited by the outer surface 11 of the housing 10. That is, although not shown in FIG. 20, the fluid purification device 40 may be rotated until its lower end contacts the outer surface 11 extending downwardly of the filter frame 12. In the illustrated embodiment, fluid purification device 40 may be rotated by a right angle.

When replacement or maintenance work on components such as the filter member 20 is completed, the fluid purification device 40 may be rotated back toward the filter frame 12. In the illustrated embodiment, the fluid purification device 40 can be rotated clockwise to tightly engage the housing 10 again.

When the rotation of the fluid purification device 40 is completed, an external force is applied to couple the coupling member 235 and the coupling protrusion 15. Accordingly, the fluid purification device 40 is again coupled to the housing 10 at a plurality of positions, that is, at the upper and lower sides in the illustrated embodiment.

Accordingly, maintenance of the fluid purification device 40 can be performed even if the fluid purification device 40 is not completely separated from the housing 10.
