Description

Fluid purification device and power device including the same

The present invention relates to a fluid purification device and a power device including the same, and more particularly, 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 capable of converting and transmitting power by being energized with external power sources and loads. The power device may receive power from an external power source, boost or step down the power, and transmit the power 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 device. When the generated heat stays inside the power device, there is a possibility that the electrical devices may be thermally damaged.

Therefore, a typical power device includes a component for cooling mounted electrical devices. For example, the power device may cool mounted electrical devices in the form of air cooling using external air.

However, various foreign substances such as dust and dirt may be mixed in the external air. When external air is introduced into the power device without a separate filtering process, mounted electrical devices may be damaged by foreign substances mixed in the external air for air cooling.

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

As the use of power equipment progresses, a significant amount of foreign matter accumulates in the filter. In this case, it is difficult to smoothly introduce the outside air, and the reliability of the filtration process may also be deteriorated. Furthermore, since the replacement cycle of the filter is shortened, time and cost required for operation of the power device may increase.

Korean Registered Patent Document No. 10-1476003 discloses a cabinet with modules having a thermosiphon cooler arrangement. Specifically, a cabinet having modules having a thermosiphon cooler arrangement capable of guiding a flow of incoming cooling air with 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 suggest a method for filtering foreign substances mixed in the air.

Korean Patent Registration No. 10-0896777 discloses a multiple power supply device having improved mountability. Specifically, a multiple power supply device capable of introducing cooling air for cooling the power device by including a separate cooling fan is disclosed.

However, the multiple power supply device presented in the prior literature also only proposes a method for introducing air for cooling into the inside, but does not suggest a method for filtering foreign substances mixed in the air for cooling.

First, the fluid purification device includes a purification module. The purification module includes a plurality of vortex forming members to form a flow of fluid introduced from the outside in the form of a vortex. As the fluid flows inside the purification module, the dust mixed with the fluid is moved radially outward by centrifugal force and is centrifuged.

A dust discharge unit is formed through the outer circumference of the purification module. The centrifuged dust is discharged into one of the spaces of the frame unit through the dust discharge unit. Fluid from which dust and the like are separated may flow into the power device through a filter member.

The external fluid may be introduced into the power device only when it sequentially passes through the fluid purifying device and the filter member. That is, the introduced external fluid is primarily filtered by the fluid purification device and then is secondarily filtered by the filter member.

Accordingly, the external fluid may firstly remove dust through a centrifugal separation process by the fluid purifying device and secondarily remove dust by the filter member and then flow into the power device. Accordingly, dust and the like mixed with the fluid can be removed multiple times, and the degree of purification of the introduced fluid can be improved.

Therefore, by the centrifugal separation process, dust having larger particles and mass among foreign substances mixed with the external fluid may be separated.

The filter member is configured to filter minute-sized particles and dust having a mass remaining in the external fluid. That is, fluid in a state in which relatively large particles and dust having a mass are previously removed passes through the filter member.

Therefore, the foreign matter mixed with the external fluid is introduced into the power device after being removed in various forms according to its size and mass. Accordingly, the foreign matter may be removed in various ways due to the physical properties of the foreign matter to be removed.

In addition, according to the configuration described above, in the fluid purifying device according to the embodiment of the present invention and the power device including the same, the durability of the filter for filtering foreign substances mixed with the fluid may be increased.

According to the configuration described above, among the foreign substances mixed with the external fluid, relatively large-sized dust and the like are separated by the fluid purification device. That is, dust mixed with the fluid flowing into the filter member has a minute size.

Accordingly, clogging of the filter member due to dust or the like separated by the filter member can be minimized. Accordingly, damage to the filter member can be prevented and durability can be increased.

The fluid purification device is removably coupled to the housing of the power appliance. A coupling member is provided on one side, for example, an upper portion of the fluid purification device, and is detachably coupled to a coupling protrusion provided in the housing. In one embodiment, the coupling member is provided in the form of a toggle clamp, so that the fluid purification device and the housing can be separated with a simple pressing operation.

(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 may form the flow of the introduced external fluid in a swirl form through the above-described configuration. The fluid introduced into the fluid purification device 40 flows in a swirl form, and mixed dust and the like may be centrifuged to be removed.

The fluid introduced into the fluid purification device 40 flows as described above, and after dust and the like are separated, the fluid may be introduced into 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 passing through at least two filtration processes.

In addition, as the fluid flows in the form of a vortex, the fluid may pass through the filter member 20 after large-sized dust and the like are removed by centrifugation. Accordingly, a phenomenon in which the filter member 20 is clogged with large-sized dust or the like can be prevented, 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 the fluid formed inside the fluid purification device 40 according to an embodiment of the present invention and the process of separating dust mixed with the fluid according to the flow will be described in detail.

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

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

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

In addition, the term "dust flow (FD)" used in the following description means a flow of dust mixed with a fluid and then separated from the fluid by being centrifuged by the flow of the fluid.

Referring to FIG. 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, so that an external fluid may flow into the purification module 300 . The rear end of the purification module 300 communicates with the second frame space 222 , so that the fluid from which dust and the like 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 introduced into the purification module 300 does not flow out arbitrarily.

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

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

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

As the first flow F1 is formed as a swirling vortex, centrifugal force is generated in the fluid in a radially outward direction, that is, in a direction toward the inner circumference 312 of the body. Accordingly, particles having a relatively large mass, that is, dust or the like of a relatively large size are moved radially outward.

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

Dust discharge units 316 are formed through the outer circumference of the body 311 and the inner circumference of the body 312 to communicate the hollow body 313 and the first frame space 212 . In one embodiment, the dust discharge unit 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 to the first frame space 212 .

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

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

Thereafter, the fluid passes through the filter member 20 and is filtered again, and then flows into the inner space of the housing 10 via the blowing fan 30 to cool the components of the power device 1 . In the above process, it will be understood that the blowing fan 30 is operated to provide a transfer force to the external fluid.

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

Therefore, components accommodated inside the housing 10 are not damaged by dust mixed with the cooling fluid. Furthermore, since the filter member 20 is configured to filter dust or the like of a relatively small size, clogging of the filter member 20 can be prevented.

In the embodiment shown in (b) of FIG. 20 , the fluid purification device 40 is in a relatively rotated state with respect 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 state is a state in which replacement or maintenance of components such as the filter member 20 can be performed.

In this state, the coupling member 235 is detached from the coupling protrusion 15 . In one embodiment, it is as described above that the coupling member 235 can be separated from the coupling protrusion 15 by application of an external force.

Meanwhile, the hinge member 233 is maintained in a rotatably coupled state to the support protrusion 14 by the shaft member 234 . As the upper side of the fluid purifying device 40 is separated from the housing 10 by the separation of the coupling member 235, the fluid purifying device 40 is rotated around the shaft member 234 to be spaced apart from the housing 10. It can be. In the illustrated embodiment, the fluid purification device 40 may be separated from the housing 10 by rotating in a counterclockwise direction.

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 can be rotated until its lower end comes into contact with the outer surface 11 extending downward of the filter frame 12 . In the illustrated embodiment, the fluid purification device 40 can be rotated by a right angle.

When replacement or maintenance of components such as the filter member 20 is completed, the fluid purification device 40 may be rotated toward the filter frame 12 again. In the illustrated embodiment, the fluid purification device 40 may be rotated in a clockwise direction to be tightly coupled to the housing 10 again.

When the rotation of the fluid purification device 40 is completed, an external force is applied so that the coupling member 235 and the coupling protrusion 15 are coupled. Accordingly, the fluid purification device 40 is again coupled to the housing 10 at a plurality of locations, 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 .
