Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings. Prior to this, the terms or words used in this specification and claims should not be construed as limited to their usual or dictionary meanings, and the inventor should appropriately define the concept of terms in order to explain his or her invention in the best way. Based on the principle of definability, it must be interpreted with meaning and concept consistent with the technical idea of the present invention.

Accordingly, the embodiments described in this specification and the configurations shown in the drawings are only one of the most preferred embodiments of the present invention and do not represent the entire technical idea of the present invention, so at the time of filing this application, various alternatives are available to replace them. It should be understood that equivalents and variations may exist.

Figure 1 is a transparent perspective view showing a protective device for electrical and electronic equipment with a dehumidifying function installed in an internal enclosed space according to a preferred embodiment of the present invention, and Figure 2 is a transparent perspective view showing the electric and electronic equipment in Figure 1, excluding the internal enclosed space. and only the protection device of the electronic equipment, FIG. 3 is a view of FIG. 2 excluding the wall of the internal enclosed space, and FIG. 4 is a perspective view of FIG. 3 excluding the housing 100.

As shown in Figures 1 to 4, the electrical and electronic equipment protection device according to a preferred embodiment of the present invention prevents the temperature of the internal enclosed space from being higher than the outside air due to heat generation due to electronic equipment located inside. , relates to an electrical and electronic equipment protection device used in an internal enclosed space where electronic equipment is installed, which prevents moisture from forming in the internal enclosed space.

An electrical and electronic equipment protection device according to a preferred embodiment of the present invention includes a housing 100, an external air flow path forming part 200, and an internal air flow path forming part 300. Here, the housing 100 is provided on one wall of an internal sealed space where electrical and electronic equipment is installed.

Next, the outside air flow path forming unit 200 supplies outside air at a temperature relatively lower than the temperature of the internal sealed space to the housing through the first fan 270 (see FIG. 12) provided on the upper part of the housing 100 described above. It is a configuration that sucks in air from the lower side of the first side 110 of the housing 100, raises the outside air upward, and discharges it to the upper side of the first side 110 of the housing 100.

This outside air flow path forming part 200 includes an outside air intake vent 210, an outside air intake ball 220, a plurality of internal pipes 230, a protector pipe 240, an outside air discharge ball 250, and an outside air discharge vent ( 260), including the first fan (270).

First, as shown in FIG. 2, the outside air intake vent 210, through the outside air intake port 211 provided on one lower side of the first surface 110 of the housing 100, provides low-temperature air that is relatively lower than the inside temperature. Inhale the outside air. Here, the outdoor air inlet 211 may be formed of a plurality of long holes extending in the up and down directions, as shown in FIG. 2. By doing this, the inflow of water, moisture, and 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 desirable to select one in a range that is not limited to the flow of external air.

Next, the outside air intake ball 220 is combined with the above-mentioned outside air intake vent 210, and its central part is relatively wide, as shown in FIG. 10, so as to form a vortex in the flow of outside air. The suction and discharge sides are relatively narrow. Furthermore, although not shown, a wrinkle structure may be formed on the inner surface of the outdoor air intake ball 220 to better induce the formation of a vortex in the flow of outdoor air. By inducing a vortex in this way, the possibility or probability of heat exchange through contact between the high temperature inside air and the swirling outside air increases.

Next, it further includes a plurality of internal pipes 230 that are elongated in the vertical direction and have internal apertures that provide a passage or path through which external air coming through the external air intake vent 210 and the external air intake ball 220 rises. . The low temperature outside air from the lower part rises through this internal pipe 230. The plurality of internal pipes 230 are also a section where high temperature air meets each other and heat exchange occurs. Fin structures of various shapes or shapes may be further included on the outer surfaces of the required plurality of internal pipes 230.

Next, the protector pipe 240 is configured to rotate and surround the plurality of internal pipes 230 described above. By placing the protect pipe 240, the internal and external air flow paths overlap in the space between the internal pipe 230 and collide with each other, thereby confining a certain portion of the internal space so that heat exchange can occur. has

Next, the outside air discharge ball 250 is located above the plurality of internal pipes 230 and the protector pipe 240, and its central part is relatively wide so as to form a vortex in the flow of outside air. The suction and discharge sides are relatively narrow. Furthermore, if necessary, as already described in the case of the outside air intake ball 220, a wrinkle structure may be formed on the inner surface of the outside air discharge ball 250 to better induce the formation of a vortex in the flow of outside air.

Next, the outdoor air discharge vent 260 is coupled to the outdoor air discharge ball 250 and discharges the outdoor air through the outdoor air outlet 261 provided on one upper side of the first surface 110 of the housing 100. . As shown in FIG. 2, the outdoor air outlet 261, like the outdoor air intake port 211, may be formed of a plurality of long holes extending in the up and down directions. By doing this, the inflow of water, moisture, and foreign substances such as raindrops can be effectively prevented.

As shown in FIGS. 10 to 13, in the direction toward the first surface of the above-described outside air intake vent 210 and outside air discharge vent 260, on the outside air flow path to prevent raindrops or foreign substances from being directly sucked from outside air. It may further include bending structures 212 and 262. As shown in Figures 10 to 13, the bending structure on the external air flow path is indicated with a red dotted line.

In addition, as shown in FIG. 2, the positions of the outdoor air inlet 211 and the outdoor air outlet 261 are located in the vertical direction of the first surface to better induce the formation of a vortex in the flow of outdoor air. They can be positioned in a staggered manner by deviating to the left and right based on the straight line. That is, in FIG. 2, it can be seen that the outdoor air intake port 211 is biased to the left based on the vertical straight line, and the location of the outdoor air outlet 261 is biased to the right based on the vertical straight line.

Next, as shown in FIGS. 2 and 3, the betting flow path forming portion 300 is formed on the second side 120 and the third side immediately adjacent to the first side 110 of the housing 100 described above. The second fan 310 and the third fan 320 provided in (130) respectively suck the relatively high temperature air from the internal enclosed space, and the air sucked through the second fan 310 and the third fan The air sucked through (320) partially overlaps or overlaps with the external air flow path, and heat exchange occurs between the protector pipe 240 and the plurality of internal pipes 230 as they collide with each other as described above. By the relatively low temperature outside air, the high temperature inside air is cooled down and then discharged from the lower part of the second side 120 and the third side 130 of the housing 100. Air discharge ports are formed on the lower second and third surfaces 120 and 130 of the housing, as well as on the fourth surface (opposite the first surface).

When maintaining temperature and humidity through electrical and electronic protection devices, it is possible to additionally provide a temperature sensor and a humidity sensor to perform feedback control, for example, PID control, to the desired target temperature and humidity. In addition, it is possible to accumulate the sensing results of the temperature sensor and humidity sensor as data and learn the data to find patterns using, for example, CNN, a deep learning algorithm. Furthermore, it is also possible to predict the temperature and humidity in the internal enclosed space in advance through a Kalman filter or extended Kalman filter.

Next, describing the dehumidifying unit 400, the dehumidifying unit 400 is configured to remove moisture from the internal enclosed space and maintain humidity in the internal enclosed space. 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 located toward the internal sealed space, and conversely, the porous cathode 420 is located toward the outside air. The power supply unit 440 applies a direct current voltage, typically about 3V, to the porous anode 410 and the porous cathode 420. The polymer electrolyte membrane 430 is sandwiched between the porous anode 410 and the porous cathode 420 described above.

Here, the porous anode 410 and the porous cathode 420 need to supply power evenly to the polymer electrolyte membrane 430 and allow air to pass through well. Therefore, the anode 410 and the cathode 420 need to be made of a porous material or the material needs to be treated to create pores.

For example, it is possible to use a porous carbon material that is excellent in terms of charge mobility and can easily create pores of hundreds of nanometers to several micrometers. In addition, the anode 410 and the cathode 420 support the polymer electrolyte membrane 430 and simultaneously serve to prevent problems such as distortion or bending of the polymer electrolyte membrane 430. In addition, resin materials, etc. may be further included for overall insulation of the dehumidifying unit 400.

O₂ + 2e^- 의 제습 반응이 일어나고, 다공성의 음극(420)에서는, 2H⁺ +

O₂ + 2e^- → H₂0 의 방습 반응이 일어나서, 각각 제습과 방습이 이루어진다. By configuring this, in the porous anode 410 described above, H ₂ 0 → 2H ⁺ +

A dehumidifying reaction of O ₂ + 2e ^- occurs, and at the porous cathode 420, 2H ⁺ +

O ₂ + 2e ^- → H ₂ 0 A moisture-proof reaction occurs, resulting in dehumidification and moisture-proofing, respectively.

In the internal enclosed space, water is decomposed into hydrogen cations and oxygen as it loses electrons, and in the outside air, the hydrogen cations that moved to the cathode 420 through the polymer electrolyte membrane 430 combine with oxygen in the outside air, that is, the atmosphere, and become water vapor. It is emitted. As a result, dehumidification occurs in the internal enclosed space.

Furthermore, the dehumidifier 400 is located at the lower part of the housing 100 or on the first side 110 adjacent to the lower part, so as to remove moisture that is likely to be generated when the high-temperature indoor air is cooled by the relatively low-temperature external air. It is desirable to be formed in .

As described above, although the present invention has been described with limited examples and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following will be understood by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalence of the claims to be described.
