1 to 4, the sterilization module 10 according to an embodiment of the present invention includes a tubular housing in which an inlet 105a and an outlet 105b are formed so that air passes through the inside. 100) and a plurality of light emitting diode units 200 for outputting ultraviolet rays through the air introduced into the housing 100.

In this specification, the surface and direction in which the air inlet 105a is formed is defined as front and front, and the surface and direction in which the air outlet is formed is defined as rear and rear.

The sterilization module 10 may use a light emitting diode (LED) that emits light in an ultraviolet (UV) wavelength range for sterilization.

The plurality of light emitting diode units 200 may include one or more light emitting diode light sources.

On the other hand, in general, ultraviolet light may be subdivided according to the length of the wavelength.

For example, ultraviolet light may be divided into UVA having a wavelength of 320 to 400 nm, UVB having a wavelength of 280 to 320 nm, and UVC having a wavelength of 200 to 280 nm.

In particular, UVC, which is a short wavelength ultraviolet ray, has a property of destroying bacterial DNA and causing a chemical reaction to a special material, and thus can be effectively used for sterilization, removal of surface or water contamination, curing, and the like.

Therefore, the plurality of light emitting diode units 200 may be UV LEDs that emit light in the ultraviolet wavelength range, and more preferably UVC LEDs using short wavelength C light sources with good sterilization effect.

In addition, the plurality of light emitting diode units 200 may output ultraviolet rays in a direction toward the inlet 105a. Accordingly, the air introduced into the inlet 105a can be sterilized to purify the contaminated air.

That is, the plurality of light emitting diode units 200 are disposed on a surface on which a discharge port 105b is formed, or at least a part is disposed at a position that is a predetermined distance forward from a surface on which the discharge port 105b is formed, and irradiates ultraviolet rays forward. can do.

The present invention can sterilize suspended microorganisms passing through the air flow path using the UV LED 200 that irradiates ultraviolet rays.

According to an embodiment of the present invention, a UV LED 200 for sterilization may be installed facing the front of the flow path.

When the UV LED 200 is installed facing the front of the flow path to irradiate light to the front of the microorganisms flowing into the flow path, the amount of ultraviolet light and exposure time are longer than when the LED is installed on the side of the flow path to irradiate light vertically to the microorganism particles. Is advantageous in

Therefore, the UV LED 200 is irradiated with ultraviolet rays in the direction toward the inlet 105a, the ultraviolet rays are irradiated to the front of the air and microorganisms flowing into the flow path, and the sterilization efficiency is increased.

In addition, when the UV LED 200 is disposed in front of the flow path, since the total amount of light is increased than when it is disposed on the side, the number of uses of the UV LED 200 can be reduced.

The arrows indicated in the drawings of the present specification illustrate the flow of air and microbial particles.

When a plurality of UV LEDs 200 are installed in front of the particle inflow direction, as the distance between the UV LEDs 200 decreases, the total amount of light increases. However, uniform light irradiation may be difficult, such as an increase in the differential pressure and a region where ultraviolet rays are not irradiated or weakly irradiated in the flow path. Therefore, it is preferable that the plurality of UV LEDs 200 are arranged at a predetermined distance.

On the other hand, the arrangement interval and structure of the UV LED 200 may be varied according to the overall shape and the internal space of the sterilization module 10. For example, in the case of the cylindrical body 101 having a wide inlet 150a, in order to irradiate uniform ultraviolet light even in a circular area close to the inner surface of the cylindrical body 101, the plurality of UV LEDs 200 are up and down. It can be arranged symmetrically left and right.

According to an embodiment, the housing 100 may include a cylindrical body 101 connecting the inlet 105a and the outlet 105b. The two-way openings of the cylindrical body 101 may be formed to have the same shape and area. In this case, the inlet 105a and the outlet 105b may be formed to have the same area.

The inner surface of the cylindrical body 101 is treated with a reflective material such as aluminum coating to further improve the sterilization performance by ultraviolet light.

The sterilization module 10 is connected to the inner surface of the housing 100, and supports 110 for supporting the plurality of light emitting diode units 200, and the plurality of light emitting diode units 200 and the inlet port Between (105a), it is disposed spaced apart from each other, to switch the direction of the air flow, it may further include a plurality of blocking film (121, 122) to block the light toward the inlet (105a).

The support unit 110 supports the light emitting diode unit 200 and can receive circuits, electric wires, and the like necessary for supplying power to the light emitting diode unit 200 therein.

The sterilization module 10 according to an embodiment of the present invention performs sterilization work on the air flowing through the air flow path in which the UV LED 200 is installed, through which the harmful ultraviolet rays are exposed to the outside. Can.

Therefore, the sterilization module 10 according to an embodiment of the present invention may include a light leakage blocking structure capable of blocking ultraviolet rays while passing air, for external blocking of harmful ultraviolet rays.

The light leakage blocking structure according to an embodiment of the present invention may be composed of a plurality of shielding films 121 and 122 and may be composed of at least two shielding films 121 and 122.

Since the sterilization module 10 according to an embodiment of the present invention has a structure in which air is introduced into the interior, there is a possibility that ultraviolet rays for sterilization are exposed to the outside through a flow path.

Particularly, when exposed to high-power UVC, it can destroy DNA in cells in a short time, which can cause fatal results to the user's eyes and skin.

Therefore, the sterilization module 10 according to an embodiment of the present invention utilizes the straightness of light to block the external exposure of ultraviolet rays by arranging a plurality of screens 121 and 122 alternately to block light while passing air. Can.

That is, a plurality of masking films 121 and 122 may be used to form a kind of maze structure inside the sterilization module 10.

2 to 4, when viewed from the front, the two screens 121 and 122 are arranged to overlap a certain portion in the center of the sterilization module 10, so that light traveling straight ahead can be completely blocked from leaking. have.

The light moving straight is blocked by the plurality of screens 121 and 122 and does not pass through the inlet 105a. Referring to the front side of the inlet that is the flow path inlet illustrated in FIG. 3, only the screens 121 and 122 are visible, and the light emitting diode unit 200 therein is not blocked by the screens 121 and 122.

In addition, some of the light emitted by the UV LED 200 in the forward direction may be blocked by the first obstruction film 121 and blocked, and some of the light emitted by the UV LED 200 may be blocked by the second obstruction layer 122.

In addition, the air introduced through the inlet 105a is blocked by the plurality of obstruction membranes 121 and 122 so that the flow direction is changed, but passes between the plurality of obstruction membranes 121 and 122 and forwards toward the inlet 105a. It can be sterilized by ultraviolet light irradiated in the direction.

When the air volume is increased, the time for exposing the air to a sufficient amount of ultraviolet light is reduced, so that the sterilization efficiency may be reduced. The screens 121 and 122 may slow the movement speed of air, thereby improving sterilization efficiency.

Depending on the embodiment, one surface of the shielding films 121 and 122 may be UV-blocking and/or reflective coating. For example, one surface in the rear direction toward the UV LEDs 200 of the shielding films 121 and 122 may be treated with a sunscreen. The UV protection coating absorbs the ultraviolet light reflected by the internal structure and prevents it from going out.

5 is a conceptual view showing the appearance of a sterilization module according to an embodiment of the present invention, Figure 6 is a side view of a sterilization module according to an embodiment of the present invention.

The sterilization module illustrated in FIGS. 5 and 6 has the largest difference in shape between the sterilization module and the housing 100 described with reference to FIGS. 1 to 4, and other parts are the same or similar. Hereinafter, the differences will be mainly described.

5 and 6, the sterilization module 10 according to an embodiment of the present invention, the housing 100 and the air introduced into the housing 100, the inlet and outlet are formed so that the air passes through the inside It may include a plurality of light-emitting diode unit 200 for outputting ultraviolet rays.

The housing 100 may include a body 102 that connects the inlet and the outlet and increases in circumferential length from the inlet to the outlet. That is, the body 102 may gradually decrease in area of a surface parallel to the inlet and outlet as the air flows forward. Accordingly, the areas of the inlet and outlet may also be different.

5 and 6, the area of the inlet port may be smaller than the area of the outlet port. For example, the body 102 becomes narrower toward the front in which air is introduced, so that the area of the inlet may be smaller than the area of the outlet.

The size of the surface formed around the front inlet side of the body 102 may be formed to be smaller than the size of the surface formed around the rear outlet side of the body 102. The body 102 is formed such that the discharge area where air is discharged is larger than the inflow area where air is introduced. That is, the body 102 widens as the flow path through which air flows toward the rear. Accordingly, the body 102 may be formed so that the internal flow path reduces the flow rate of air.

5 and 6, the front plate 131 is disposed on the front inlet side of the body 102 to reinforce the support rigidity and to facilitate the attachment and connection of the sterilization module 10 to other devices or locations, A rear plate 132 may be disposed on the rear discharge port side of the body 102.

When a plurality of UV LEDs 200 are installed facing the front of the flow path and irradiating light to the front of the microorganisms flowing into the flow path, the amount of ultraviolet light and Advantageous in exposure time, the efficiency of sterilization flowing into the flow path may be increased.

When a plurality of UV LEDs 200 are installed in front of the particle inflow direction, as the distance between the UV LEDs 200 decreases, the amount of light increases and the microbial sterilization efficiency increases. can do.

In addition, when irradiating UV LED light in the vertical direction of the particle inflow direction, there is a problem that the number of LEDs needs to be increased because the total amount of light is reduced, compared to the front irradiation.

In addition, when the distance between the LEDs 200 is narrowly installed in the flow path, a differential pressure is generated, and thus an additional fan design is required to maintain a desired product air volume.

Accordingly, the plurality of UV LEDs 200 are disposed spaced a predetermined distance, and it is preferable to output ultraviolet light in front of the particle inflow direction.

The sterilization module 10 may include a support portion 110 connected to the inner surface of the body 102 to support the plurality of light emitting diode units 200.

Also in this embodiment, the sterilization module 10 may further include a plurality of screens that switch the direction of air flow and block light flowing out through the inlet.

In the present embodiment, the area of the cover layer disposed close to the inlet port among the plurality of cover layers may be smaller than the area of the cover layer disposed close to the discharge port.

The plurality of shielding membranes block ultraviolet rays by using a straight property of light, but a flow path can be secured.

7A and 7B are diagrams for reference to a description of an ultraviolet light leakage blocking structure according to an embodiment of the present invention.

7A and 7B, a light leakage blocking structure according to an embodiment of the present invention may include a plurality of shielding films 711, 712, and 713. By using the three masking films 711, 712, and 713, a kind of maze structure that blocks light can be formed inside the sterilization module 10.

7A and 7B, when viewed from the front, the three screens 711, 712, and 713 are arranged to overlap a certain portion in the center of the sterilization module 10, so that the light traveling straight through is leaking It can be completely blocked.

The light moving straight is blocked by at least one of the three screens 711, 712, and 713, so that it cannot pass through the inlet.

In addition, as shown in FIG. 7A, air introduced through the front inlet port may be blocked by the plurality of obstruction membranes 711, 712, and 713 and the flow direction may be changed while passing between the plurality of obstruction membranes 711, 712, and 713. . Light passing between the shielding layers 711, 712, and 713 may be sterilized by ultraviolet light irradiated from the UV LED 200.

When the air volume is increased, the time for exposing the air to a sufficient amount of ultraviolet light is reduced, so that the sterilization efficiency may be reduced. Conversely, the plurality of shielding films 711, 712, and 713 may slow the movement speed of air, thereby improving sterilization efficiency.

8A and 8B are diagrams for reference to a description of an ultraviolet light leakage blocking structure according to an embodiment of the present invention.

8A and 8B, a light leakage blocking structure according to an embodiment of the present invention may be formed of a plurality of shielding films 811, 812, and 813. By using three masking films 811, 812, and 813, a kind of maze structure that blocks light can be formed inside the sterilization module 10.

8A and 8B, when viewed from the front, three screens 811, 812, and 813 are arranged to overlap each other, so that light traveling in a straight line can be completely blocked from leaking.

The light moving straight is blocked by at least one of the three screens 811, 812, and 813, so that it cannot pass through the inlet.

In addition, as shown in FIG. 8A, air introduced through the front inlet port may be blocked by the plurality of obstruction membranes 811, 812, and 813 while the flow direction may be changed, and may pass between the plurality of obstruction membranes 811, 812, 813. . Light passing between the shielding films 811, 812, and 813 may be sterilized by ultraviolet light irradiated from the UV LED 200. Also in this case, the plurality of screens 811, 812, and 813 can slow the movement speed of the air, thereby improving sterilization efficiency.

On the other hand, the light emitting diode unit 200, the higher the light output, the better the sterilization ability. However, when increasing the light output, it may be difficult to secure stable quality due to heat generation or the like. Therefore, an effective heat dissipation structure is required.

The sterilization efficiency can be improved by increasing the light output of the UV LED. In addition, it is possible to increase the sterilization efficiency by installing the UV LED in the direction and front of the flow path.

High-power UV LED, there is a problem in that a large amount of heat is generated when driving, and if the generated heat is not properly radiated to the outside, efficiency is reduced.

9 is a view referred to in the description of a conventional heat dissipation structure.

Referring to FIG. 9, the ultraviolet LED 910 is mounted on the substrate 920, and a heat radiation plate 930 having a general heat dissipation structure is disposed on the rear surface of the substrate 920 to contact.

However, when the UV LED 910 is installed in the direction and the front of the flow path, turbulence may occur in the front end of the UV LED 910 and the substrate 920, resulting in a decrease in heat dissipation efficiency.

Therefore, it is necessary to improve the heat dissipation efficiency by installing the LEDs in the direction and front of the flow path while maximizing the sterilizing power and simultaneously deforming the heat dissipation structure.

10 and 11 are views for reference to the description of the heat dissipation structure according to an embodiment of the present invention.

10 and 11, a plurality of light emitting diode units 200 according to an embodiment of the present invention includes a substrate 1020, a light emitting diode 1010 mounted on the substrate 1020, and the substrate 1020 ) May include a heatsink (1030) connected to.

A light emitting diode 1010 and circuit elements for driving the light emitting diode 1010 may be mounted on the substrate 1020.

According to an embodiment, the heat sink 1030 may include a cylindrical base 1110 and a plurality of heat dissipation fins 1130 extending in an outer direction away from the substrate 1020 from the base 1110. have. The outer direction may be a direction toward the inner surface of the housing 100 described with reference to FIGS. 1 to 4.

That is, when the substrate 1020 and the light emitting diode 1010 mounted on the substrate 1020 are disposed to face the front direction of the sterilization module 10, the plurality of heat radiation fins 1130 may be formed to extend in the lateral direction. Can.

Accordingly, a long heat dissipation fin 1130 can be formed to secure a sufficient heat dissipation area.

In addition, by passing air through the space formed between the adjacent heat sink fins 1130, turbulence is prevented, and the heat radiation effect can be further improved.

The present invention can improve cooling efficiency by using a heat sink 1030 including a heat dissipation fin 1130 extending in a lateral direction from the base 1110 to secure a sufficient heat dissipation area. In addition, the plurality of heat dissipation fins 1130 are formed to be spaced apart from each other so that air can pass therethrough, preventing turbulence, and the heat dissipation effect can be further improved. The space between the spaced apart heat dissipation fins 1130 has an effect of increasing the heat dissipation efficiency while smoothing the flow of air.

In addition, the light emitting diode unit 200 according to an embodiment of the present invention can minimize the volume by configuring the LED and the heat dissipation structure as one module.

10 and 11, the plurality of heat dissipation fins 1130 may be formed to have two or more bending angles b, respectively.

In order to increase the effectiveness of fins in the effectiveness of heat dissipation fins, the heat conduction coefficient and the receiving circumference must be large, and the convective heat transfer coefficient and the cross-sectional area of the fin must be small. Assuming that the heat conduction coefficient and the convective heat transfer coefficient are constant values, the pin validity increases when the circumference of the pin is larger than the cross-sectional area of the pin.

That is, in order to increase the heat dissipation performance by convection cooling, a high surface area ratio to the heat radiation fin cross-sectional area is required. To this end, in the heat dissipation structure having the same volume, as the angle of bend (b) is increased, an effect of increasing the surface area may be obtained, and heat dissipation performance may be improved.

The spacing (d) of the heat dissipation fins may be set to increase the number of heat dissipation fins and heat dissipation performance by convection cooling.

The larger the thickness t of the heat dissipation fin, the greater the number of Nu. This is because as the thickness increases, the basic area received by the heat flux increases, and thus receives a lot of heat energy, and heat dissipation increases due to convective heat transfer rather than conduction heat transfer.

For example, the spacing (d) of the heat dissipation fin is 1.0 to 1.5 mm, and the thickness (t) of the heat dissipation fin at .0 to 1.5 mm spacing is 1.9 mm for optimal heat dissipation performance.

The light emitting diode unit 200 according to the present invention is arranged to face the air flow path in front, and the heat sink 1030 disposed on the rear side can further increase the heat dissipation performance by using air without inhibiting the flow of air. .

That is, the spacing between the radiating fins, the thickness of the radiating fins, and the bending angle of the radiating fins can be the main variables in the radiating performance. At this time, in order to facilitate the flow of air passing through the flow path, the spacing between the radiating fins is appropriate, and the thicker the radiating fin is, the larger the bending angle of the rotating fin is to increase the surface area of the heat sink.

In the case of a device for air sterilization by installing the LED inside, the LED is usually attached to the inside of the product, and there is a disadvantage in that the sterilization efficiency is reduced by shining light on the side of the flow path.

However, in the present invention, UV LEDs are arranged to face the flow path in order to increase the sterilization efficiency of the LED for sterilization.

In this case, the heat dissipation performance may be deteriorated by installing a heat sink having a general structure.

In order to compensate for this, the present invention can manufacture the heatsink structure to a structure that does not inhibit the flow of air, thereby maintaining the disinfection performance of the UV LED while maximizing the heat dissipation performance.

12 and 13 are views for reference to a description of a heat dissipation structure according to an embodiment of the present invention.

12 and 13, a plurality of light emitting diode units 200 according to an embodiment of the present invention includes a substrate 1220, a light emitting diode 1210 mounted on the substrate 1220, and the substrate 1220 It may include a heat sink 1230 connected to.

According to an embodiment, the heat sink 1230 may include a cylindrical base 1310 and a plurality of heat dissipation fins 1330 extending in an outer direction away from the substrate 1220 from the base 1310. have. The outer direction may be a direction toward the inner surface of the housing 100 described with reference to FIGS. 1 to 4.

That is, when the substrate 1220 and the light emitting diode 1210 mounted on the substrate 1220 are disposed to face the front direction of the sterilization module 10, the plurality of heat radiation fins 1230 may be formed to extend in the lateral direction. Can.

In addition, the heat sink 1230 according to an embodiment of the present invention may be configured to streamline the front portion of the heat dissipation fin 1330 to minimize air resistance. Based on the sterilization module 10 described with reference to FIGS. 1 to 4, the plurality of heat dissipation fins 1330 may have a streamlined front face toward the inlet 105a.

That is, by forming the front portion of the heat dissipation fin 1330 disposed in a direction in which air flows in a streamlined shape, air can be more smoothly passed through.

If the cross-section of the heat sink fin is perpendicular to the air flow direction, a structure for restraining the flow of air is formed, there is a risk of turbulence, and the air resistance coefficient is high, so the flow velocity may be lowered.

Therefore, a heat sink fin structure in a direction in which air is introduced can be formed in a streamlined shape. In the case of a streamlined heat dissipation fin, it is possible to increase the heat dissipation effect due to the heat dissipation fin by smoothing the flow of air by reducing the air resistance coefficient.

14 is a view referred to for a description of a heat dissipation structure according to an embodiment of the present invention.

Referring to FIG. 14, a plurality of light emitting diode units 200 according to an embodiment of the present invention is connected to a substrate 1420, a light emitting diode 1410 mounted on the substrate 1420, and the substrate 1420 It may include a heat sink (1430).

According to an embodiment, the heat sink 1430 may be a mesh type heat sink having a plurality of openings 1435 through which air passes.

In the case of a mesh-type heat dissipation structure, it can be formed of a material or structure having high thermal conductivity while easily passing air, such as porous aluminum or aluminum mesh.

The larger the size of the opening 1435, and the thinner the thickness of the mesh frame skeleton, the more advantageous the heat dissipation efficiency.

In the present invention, a high-power UV LED is disposed on the front of the flow path, and a heat sink having a structure through which air can flow can be installed on the back of the UV LED to increase both air sterilization efficiency and heat dissipation efficiency.

The present invention relates to an ultraviolet (UV) LED air sterilization module, and more particularly, to a sterilization module that is effectively installed in an air conditioner including an air flow path and sterilizing microorganisms in the air.
