Description

Device for improving durability based on dehumidifying elements

[0001] The present invention relates to a device for improving durability based on a dehumidifying element, and to a device for protecting electrical and electronic equipment, and more specifically, to a device for protecting electrical and electronic equipment, which can prevent problems caused by high heat generated from electrical and electronic equipment even when installed in an internal sealed space to protect the electrical and electronic equipment from dust, raindrops, moisture, etc. from the outside, that is, it relates to a device for protecting electrical and electronic equipment, which can dehumidify while maintaining the temperature of the internal sealed space in which the electrical and electronic equipment is installed.

[0002] For various reasons, in many situations where electrical and electronic equipment must be installed outdoors rather than indoors, it is necessary to prevent foreign substances such as raindrops, moisture, and dust from entering the electrical and electronic equipment, which can be fatal to the electrical and electronic equipment or at least accelerate its aging.

[0003] The simplest solution is to install electrical and electronic equipment inside a sealed structure, which blocks moisture and dust, but naturally, the problem of heat generation from the electrical and electronic equipment is that it cannot be addressed by adopting a sealed structure.

[0004] A related prior art patent document is Korean Patent No. 10-1717619 (registered on March 13, 2017, title of invention: DEHUMIDIFICATION APPARATUS). This prior art patent document discloses a "general purpose dehumidification device in which a housing having a built-in dehumidifying member is applied to a dehumidifying target (such as lighting such as streetlights or vehicle lamps, power distribution and communication equipment, security equipment, and outdoor or indoor electronic enclosures such as solar power systems, etc.), and an external valve that opens and closes the external communication part of the housing removes internal moisture (closes the external valve) when the dehumidifying target is low in temperature, and when the dehumidifying target is high in temperature, the moisture in the dehumidifying member is discharged to the outside by opening the external valve together with the temperature inside the lamp module."

[0005] However, as in the present invention, there is no disclosure at all of a protection device for electrical and electronic equipment that can prevent problems caused by high heat generated from electrical and electronic equipment even when installed in an internal sealed space to protect the electrical and electronic equipment from external dust, raindrops, moisture, etc., that is, that can dehumidify while maintaining the temperature of the internal sealed space where the electrical and electronic equipment is installed.

[0007] [Patent Document]

[0008] (Patent Document 1) Republic of Korea Patent No. 10-1717619 (registered on March 13, 2017, title of invention: Dehumidification Apparatus)

[0009] The present invention was created to solve the above-mentioned problems, and the purpose of the present invention is to provide a protection device for electrical and electronic equipment that can prevent problems caused by high heat generated from electrical and electronic equipment even when installed in an internal sealed space to protect the electrical and electronic equipment from external dust, raindrops, moisture, etc., that is, can dehumidify while maintaining the temperature of the internal sealed space in which the electrical and electronic equipment is installed.

[0010] In order to achieve the above object, a preferred embodiment of the present invention provides an electrical and electronic equipment protection device used in an internal sealed space in which electronic equipment is installed, which prevents the temperature of an internal sealed space from being higher than the outside air due to heat generation caused by electronic equipment located therein and prevents moisture from forming in the internal sealed space, the electrical and electronic equipment protection device comprising: a housing (100) provided on one wall surface of the internal sealed space; an external air passage forming unit (200) which, through a first fan provided on an upper portion of the housing, sucks in external air having a temperature lower than the temperature of the internal sealed space from a lower side of a first surface (110) of the housing, raises the external air, and discharges the external air to an upper side of the first surface of the housing; And a second fan and a third fan provided on the second surface (120) and the third surface (130) adjacent to the first surface of the housing, respectively, to suck in the internal air of the internal sealed space, so that the internal air sucked through the second fan and the internal air sucked through the third fan partially overlap with the external air passage and collide with each other, thereby cooling the internal air by the external air and causing it to descend, and then discharge it from the lower part of the second surface and the lower part of the third surface of the housing.

[0011] Here, the outside air passage forming part (200) includes: an outside air intake vent (210) for intake of outside air through an outside air intake port (211) provided on one side of the lower portion of the first surface of the housing; an outside air intake ball (220) coupled to the outside air intake vent and having a relatively wide central portion and relatively narrow suction and discharge sides so as to form a swirl in the flow of the outside air; a plurality of inner pipes (230) that provide a passage through which the outside air rises; a protector pipe (240) that rotates and surrounds the plurality of inner pipes; an outside air discharge ball (250) positioned above the plurality of inner pipes and the protector pipe and having a relatively wide central portion and relatively narrow suction and discharge sides so as to form a swirl in the flow of the outside air; And it includes an outside air discharge vent (260) that is combined with the outside air discharge ball and discharges the outside air through an outside air discharge port (261) provided on one side of the upper part of the first surface of the housing.

[0012] In addition, it is preferable to form a wrinkle structure on the inner surface of the external air intake ball (220) and the external air discharge ball (250) to better induce swirl formation in the flow of the external air.

[0013] In addition, it is preferable to further include a folded structure (212, 262) on the outside air passage in the direction toward the first surface of the outside air intake vent (210) and the outside air discharge vent (260) so that raindrops or foreign substances are not directly sucked in from the outside air.

[0014] In addition, in order to better induce swirl formation in the flow of the outside air, it is preferable that the positions of the outside air intake port (211) and the outside air exhaust port (261) be offset to the left and right with respect to the up-down direction of the first surface and are staggered from each other.

[0015] Meanwhile, the electrical and electronic equipment protection device according to the present invention further includes a dehumidifying unit (400) that removes moisture from the internal sealed space and maintains the humidity of the internal sealed space.

[0016] In addition, the dehumidifying unit (400) comprises a porous anode (410) positioned in the direction of the internal sealed space; a porous cathode (420) positioned toward the outside; a power supply unit (440) that applies a direct current voltage to the porous anode and the porous cathode; and a polymer electrolyte membrane (430) interposed between the porous anode and the porous cathode.

[0017] Here, in the porous anode (410), H20 → 2H + + O2+ 2e - The reaction occurs, and in the porous cathode (420), 2H + + O2+ 2e - → H20 As a reaction occurs, dehumidification and moisture release are achieved respectively, and as a result, the internal sealed space is dehumidified and humidity can be maintained at a constant level.

[0018] In addition, it is preferable that the dehumidifying unit is formed on the lower portion of the housing or the first surface adjacent to the lower portion so as to remove moisture generated as the bet is cooled.

[0020] It is possible to control the temperature and humidity of the internal sealed space to be maintained constant, and it is possible to maintain the temperature of the internal air of the internal sealed space at the same or slightly higher level than the temperature of the relatively low-temperature outside air. That is, the internal air sucked in through the second fan (310) and the internal air sucked in through the third fan (320) are made to partially overlap or overlap with the outside air path, and heat exchange occurs well between the protector pipe (240) and the plurality of internal pipes (230) by colliding with each other. In addition, it is possible to allow the high-temperature internal air to remain in the housing for a little longer through the housing, and it is possible to improve the heat exchange efficiency by additionally installing fins of various shapes on the outer surfaces of the plurality of internal pipes. Furthermore, efficient dehumidification of the internal sealed space is possible.

[0034] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Prior to this, it should be noted that the terms and words used in this specification and claims should not be construed as limited to their conventional or dictionary meanings. Based on the principle that the inventor can appropriately define the concepts of terms to best explain his or her invention, they should be interpreted in a way that conforms to the technical spirit of the present invention.

[0035] Accordingly, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Therefore, it should be understood that there may be various equivalents and modified examples that can replace them at the time of filing this application.

[0036] FIG. 1 is a transparent perspective view showing a protective device for electrical and electronic equipment according to a preferred embodiment of the present invention installed in an internal sealed space, FIG. 2 shows only the protective device for electrical and electronic equipment, excluding the internal sealed space in FIG. 1, in which the blue color indicates the external air path, and FIG. 3 shows a view excluding the wall surface of the internal sealed space in FIG. 2, in which the red color indicates the internal air path and collisions, etc.

[0037] As illustrated in FIGS. 1 to 4, an electrical and electronic equipment protection device according to a preferred embodiment of the present invention is an electrical and electronic equipment protection device used in an internal sealed space in which electronic equipment is installed, which prevents the temperature of the internal sealed space from being higher than the outside air due to heat generation caused by electronic equipment located therein, and prevents moisture from forming in the internal sealed space.

[0038] An electrical and electronic equipment protection device according to a preferred embodiment of the present invention includes a housing (100), an external air passage forming portion (200), and an internal air passage forming portion (300). Here, the housing (100) is configured to be provided on one side wall of an internal sealed space in which electrical and electronic equipment is installed.

[0039] Next, the outside air flow path forming unit (200) is configured to suck outside air having a temperature relatively lower than that of the internal sealed space from the lower side of the first surface (110) of the housing (100) through the first fan (270) (see FIG. 12) provided on the upper side of the housing (100) described above, and cause the outside air to rise upward and be discharged to the upper side of the first surface (110) of the housing (100).

[0040] Such an external air flow path forming part (200) includes an external air intake vent (210), an external air intake ball (220), a plurality of internal pipes (230), a protector pipe (240), an external air discharge ball (250), an external air discharge vent (260), and a first fan (270).

[0041] First, the outside air intake vent (210), as illustrated in FIG. 2, intakes outside air having a relatively lower temperature than the inside through an outside air intake port (211) provided on one side of the lower portion of the first surface (110) of the housing (100). Here, the outside air intake port (211) may be formed as a plurality of long holes extending vertically, as illustrated in FIG. 2. By doing so, the inflow of water, moisture, foreign substances, such as raindrops, can be effectively prevented. Additionally, it is possible to install a filter to prevent the inflow of foreign substances, but it is preferable to select one that is not limited by the outside air flow.

[0042] Next, the outside air intake ball (220) is combined with the above-described outside air intake vent (210), and is formed so that the central portion thereof is relatively wide and the suction and discharge sides are relatively narrow, as illustrated in FIG. 10, etc., so as to form a swirl in the outside air flow. Furthermore, although not illustrated, a wrinkled structure may be formed on the inner surface of the outside air intake ball (220) to induce a better swirl in the outside air flow. By inducing a swirl in this way, the possibility or probability of heat exchange through contact between the high-temperature inside air and the swirling outside air increases.

[0043] Next, it further includes a plurality of internal pipes (230) that are long in the vertical direction and have internal holes that provide a passage or path for the outside air to rise through the outside air intake vent (210) and the outside air intake ball (220). The low-temperature outside air at the bottom rises through these internal pipes (230). The plurality of internal pipes (230) are also sections where the high-temperature inside air meets each other and heat exchange occurs. The outer surfaces of the plurality of required internal pipes (230) may further include fin structures of various shapes or forms.

[0044] Next, the protector pipe (240) is configured to rotate and surround the plurality of internal pipes (230) described above. By placing the protector pipe (240), a certain portion of the space is confined within the space between the internal pipes (230) described above, so that the internal and external air can overlap each other and collide with each other to cause heat exchange.

[0045] Next, the outside air discharge ball (250) is positioned on top of the plurality of internal pipes (230) and protector pipes (240) described above, and is formed so that the central portion thereof is relatively wide and the suction and discharge sides are relatively narrow so as to form a swirl in the outside air flow described above. Furthermore, if necessary, as already described in the outside air intake ball (220), a wrinkle structure may be formed on the inner surface of the outside air discharge ball (250) so as to better form a swirl in the outside air flow.

[0046] Next, the outside air exhaust vent (260) is coupled with the outside air exhaust ball (250) and discharges the outside air through the outside air exhaust port (261) provided on the upper side of the first surface (110) of the housing (100). As illustrated in Fig. 2, the outside air exhaust port (261) may be formed by a plurality of long holes extending in the vertical direction, similar to the outside air intake port (211). By doing so, the inflow of water, moisture, and foreign substances such as raindrops can be effectively prevented.

[0047] As illustrated in FIGS. 10 to 13, in the direction toward the first surface of the above-described outside air intake vent (210) and outside air exhaust vent (260), a folded structure (212, 262) may be further included on the outside air passage to prevent raindrops or foreign substances from being directly sucked in from the outside air. As illustrated in FIGS. 10 to 13, the folded structure on the outside air passage is indicated by a red dotted line.

[0048] In addition, as illustrated in FIG. 2, in order to better induce swirl formation in the flow of outside air, the positions of the outside air intake port (211) and the outside air outlet port (261) may be staggered to the left and right with respect to the vertical straight line of the first surface. That is, in FIG. 2, it can be seen that the outside air intake port (211) is tilted to the left with respect to the vertical straight line, and the position of the outside air outlet port (261) is tilted to the right with respect to the vertical straight line.

[0049] Next, the inner air passage forming part (300) is formed by the second fan (310) and the third fan (320) respectively provided on the second side (120) and the third side (130) immediately adjacent to the first side (110) of the housing (100) described above, as illustrated in FIGS. 2 and 3, respectively, to suck in relatively high-temperature inner air of the internal sealed space, such that the inner air sucked in through the second fan (310) and the inner air sucked in through the third fan (320) partially overlap or overlap with the outside air passage, and heat exchange occurs between the protector pipe (240) and the plurality of inner pipes (230) as described above by colliding with each other. The high-temperature inner air is cooled by the relatively low-temperature outside air, descends, and then discharged from the lower part of the second side (120) and the lower part of the third side (130) of the housing (100). An exhaust outlet is formed on the lower second side (120) and third side (130) of the housing, and further on the fourth side (the opposite side of the first side).

[0050] When maintaining temperature and humidity through electrical and electronic protection devices, additional temperature and humidity sensors can be installed to achieve feedback control, such as PID control, to achieve the desired target temperature and humidity. Furthermore, the sensing results from the temperature and humidity sensors can be accumulated as data, and the data can be learned and used to identify patterns using deep learning algorithms such as CNNs. Furthermore, it is possible to predict the temperature and humidity in an enclosed space in advance using a Kalman filter or an extended Kalman filter.

[0051] Next, the dehumidifying unit (400) will be described. The dehumidifying unit (400) includes a porous anode (410), a porous cathode (420), a power supply unit (440), and a polymer electrolyte membrane (430). The porous anode (410) is positioned toward the internal sealed space, and conversely, the porous cathode (420) is positioned toward the outside air. The power supply unit (440) applies a DC voltage, typically a DC voltage of about 3 V, to the porous anode (410) and the porous cathode (420). The polymer electrolyte membrane (430) is a configuration interposed between the porous anode (410) and the porous cathode (420) described above.

[0052] Here, the porous anode (410) and the porous cathode (420) need to evenly supply power to the polymer electrolyte membrane (430) while allowing good airflow. Therefore, the anode (410) and the cathode (420) need to be implemented with a porous material or need to be treated to create pores in the implemented material.

[0053] For example, it is possible to utilize a porous carbon material that is excellent in terms of charge mobility and in which pores of several hundred nanometers to several micrometers are easily formed. In addition, the anode (410) and cathode (420) support the polymer electrolyte membrane (430), thereby simultaneously preventing problems such as distortion or warping of the polymer electrolyte membrane (430). In addition, a resin material or the like may be further included for the overall insulation of the dehumidifying unit (400).

[0054] By configuring it this way, in the porous anode (410) described above, H20 → 2H + + O2+ 2e - The dehumidification reaction occurs, and in the porous cathode (420), 2H + + O2+ 2e - → H20 A moisture-proof reaction occurs, and dehumidification and moisture-proofing occur respectively.

[0055] In the internal sealed space, water is decomposed into hydrogen cations and oxygen as electrons are stolen, and in the external air, hydrogen cations that have moved to the cathode (420) through the polymer electrolyte membrane (430) combine with oxygen in the external air, i.e., the atmosphere, and are discharged as water vapor. As a result, dehumidification is achieved in the internal sealed space.

[0056] Furthermore, it is preferable that the dehumidifying unit (400) be formed on the lower part of the housing (100) or on the first surface (110) adjacent to the lower part so as to remove moisture, etc., which is likely to occur when the high-temperature internal air is cooled by the relatively low-temperature external air.

[0057] As described above, although the present invention has been described by limited embodiments and drawings, the present invention is not limited thereto, and various modifications and variations are possible by a person having ordinary skill in the art to which the present invention pertains within the scope of the technical idea of ​​the present invention and the equivalent scope of the claims to be described below.
