[0025] Some embodiments of the present disclosure will be described in detail below with reference to the drawings. When referring to components in each drawing, it should be noted that the same components are given the same reference numerals as much as possible even if they are shown in different drawings. In addition, when describing the present disclosure, if a detailed description of related known configurations or functions is deemed to obscure the gist of the present disclosure, the detailed description will be omitted.

[0026] In describing components of the embodiments of the present disclosure, reference numerals such as 1, 2, i), ii), a), b) are used. Such reference numerals are used to distinguish the components from other components, and do not limit the essence, order, sequence, etc. of the components. When a part in this specification "includes" or "has" a certain component, this does not mean that other components are excluded, but that other components may be further included, unless explicitly stated to the contrary.

[0027] FIG. 1 is a rear perspective view of a wireless communication device according to an embodiment of the present disclosure.

[0028] FIG. 2 is a front perspective view of a wireless communication device according to an embodiment of the present disclosure.

[0029] 1 to 3, a wireless communication device 10 includes a main case 12, a radome 11, a heat sink 17, an upper shielding film 13, a cover 14, and a handle 15.

[0030] The main case 12 defines an accommodation space that is open forward, and is formed to have a narrow front-to-rear accommodation width that is approximately long in the vertical direction. The main case 12 is formed in a rectangular parallelepiped shape.

[0031] A radome 11 is disposed on the front surface of the main case 12. The radome 11 is made of a material that shields the accommodation space and allows electromagnetic waves to pass through.

[0032] An accommodation space is formed between the radome 11 and the main case 12. A large number of heat generating elements are arranged in the accommodation space. For example, the heat generating elements in the accommodation space include a PA (Power Amplifier) ​​element, a semiconductor element for RFIC, or an LNA (Low Noise Amplifier) ​​element. Here, the PA element is an RF element with high output power as a transistor that is the main heat generating component of a high frequency power amplifier, and generates a larger amount of heat than the semiconductor element for RFIC or the LNA element.

[0033] While the wireless communication device 10 is operating, the heat generating element continuously generates heat, and the heat dissipation part 17 disposed on the rear surface of the radome 11 dissipates the heat in the accommodation space to the outside. The heat dissipation part 17 has a plurality of heat dissipation fins 171 protruding from the opposite side of the accommodation space. The plurality of heat dissipation fins 171 improves heat dissipation efficiency by maximizing the surface area in contact with the outside. The heat dissipation part 17 is configured to integrally cover the entire rear surface of the accommodation space, but is not limited thereto, and one heat dissipation part 17 is disposed on each of the left and right sides as shown in FIG. 3.

[0034] The upper shielding film 13 is disposed to contact the rear end of the upper surface of the main case, and a plurality of first through holes 131 are formed in the upper shielding film 13. The first through holes 131 have various shapes (e.g., circular or elliptical) in cross section. Hereinafter, a case where the first through holes 131 have a circular shape will be described as an example.

[0035] The upper shielding film 13 is disposed adjacent to the rear upper end of the heat dissipation unit 17, and heat generated in the plurality of heat dissipation fins 171 is dissipated through the plurality of first through holes 131 of the upper shielding film 13. In addition, the upper shielding film 13 is made of a material that does not allow sunlight to pass through or that reflects sunlight in the areas other than the plurality of first through holes 131. Therefore, the upper shielding film 13 serves as a shielding film to prevent sunlight from directly irradiating the heat dissipation unit 17. In other words, the upper shielding film 13 is configured to prevent the heat dissipation unit 17 from being directly exposed to sunlight, while at the same time dissipating heat generated from the heat dissipation unit 17 to the outside.

[0036] 4 is a side cross-sectional view of a wireless communication device according to an embodiment of the present disclosure. Referring to FIG. 4, the thickness h of the upper shielding film 13 is formed thick to minimize the amount of sunlight irradiated inside. For example, the thickness h of the upper shielding films 13 is greater than or equal to twice the diameter d of the first through-hole 131. The first through-hole 131 is formed penetrating the upper shielding film 13 in a direction parallel to the longitudinal direction of the heat dissipation part 17.

[0037] Depending on the thickness of the upper shielding film 13 and the penetrating direction of the first through-holes 131, sunlight can be blocked so that only light close to the penetrating direction of the first through-holes 131 is irradiated to the inside. That is, the upper shielding film 13 according to the embodiment of the present disclosure ventilates the internal heat generated by the heat dissipation part 17 to the outside, while minimizing the amount of sunlight irradiated from the outside, thereby increasing the heat dissipation effect.

[0038] The penetration direction of the first through-holes 131 is not limited thereto, and the first through-holes 131 may be formed to penetrate at a predetermined angle from the longitudinal direction of the heat dissipation part 17. The upper shielding film 13 is configured to be freely separated and assembled, and the upper shielding film 13 having the first through-holes 131 penetrating in a direction that blocks sunlight to the maximum extent according to the arrangement direction of the wireless communication device 10 is appropriately assembled to maximize the sunlight blocking efficiency.

[0039] The upper shielding film 13 is disposed so that one end abuts against the rear end of the upper surface of the main case 12 and the other end abuts against the upper end of the lid part 14. At least a portion of the upper shielding film 13 has a horizontal surface, and at least another portion is formed to have a downward slope as it goes outward. Here, the outward refers to the direction toward the lid part 14. That is, of the upper shielding film 13, the portion adjacent to the main case 12 has a horizontal surface, and the portion adjacent to the lid part 14 has a downward slope. As the upper shielding film 13 has a downward slope, the heat generated from the heat dissipation part 17 can be ventilated to the outside more efficiently.

[0040] The lid 14 is disposed on the rear surface of the main case 12 and is configured to be opened and closed, and has a plurality of second through holes 141 formed therein. The lid 14 can protect the cable 16 and the heat dissipation unit 17 disposed therein from external impact. Furthermore, by disposing the lid on the rear surface of the main case 12, the cable that extends to the lower end of the conventional wireless communication device 10 can be moved to the space between the lid 14 and the heat dissipation unit 17, thereby improving the aesthetics of the wireless communication device 10. The lid 14 has a plurality of second through holes 141 formed therein, but the second through holes 141 are formed so that the heat dissipation unit 17 and the cable 16 are not visible from the outside. The second through holes 141 are used as a passage for ventilating the heat generated from the heat dissipation unit 17 to the outside, similar to the first through holes 131.

[0041] FIG. 5 is a plan view of a wireless communication device according to an embodiment of the present disclosure.

[0042] Referring to FIG. 5, the cover 14 is opened and closed by rotating around the vertical rotation axes A1 and A2 located on at least one of the left and right sides of the wireless communication device 10. For convenience of explanation, the upper shielding film 13 is omitted in FIG. 5. As shown in FIG. 5, the cover 14 is composed of two parts, and is opened and closed by rotating around the vertical rotation axis A1 located on the left side of the wireless communication device 10 and the vertical rotation axis A2 located on the right side of the wireless communication device 10. However, the present invention is not limited to this, and the cover 14 may be composed of one cover 14 covering the entire back surface of the heat dissipation part 17, and may be opened and closed by rotating around the vertical rotation axes A1 and A2 located on one of the left and right sides of the wireless communication device 10. Other opening and closing methods that can be modified by ordinary engineers are within the scope of the present invention.

[0043] The cover 14 has an arch-shaped cross-sectional structure as a whole, but is not limited thereto, and may have any shape that has a sufficient space for arranging a cable between the heat dissipation part 17 and the cover 14. When the wireless communication device 10 is in operation, the heat dissipation fins 171 of the heat dissipation part 17 have a high temperature, so that when a worker or the like performs maintenance on the wireless communication device 10 in a place where many wireless communication devices 10 are installed, there is a risk of burns if the heat dissipation fins 171 are exposed to the outside. In the case of the present disclosure, by additionally configuring the cover 14, there is an effect of protecting the worker from such a risk of burns. In other words, the cover 14 serves as a finger guard.

[0044] The fixing portion 18 is configured to fix the lid portion 14 in an open state when the lid portion 14 is opened. A locking portion is formed to protrude from a free end of the fixing portion 18. The locking portion is configured to fit into a part of the inner wall of the lid portion 14 when the lid portion 14 is in an open state. A fitting groove is formed in the inner wall of the lid portion 14 at a position corresponding to the locking portion. When the lid portion 14 is opened to perform maintenance on the wireless communication device 10, the fixing portion 18 is used to prevent the lid portion 14 from closing due to wind, etc.

[0045] The handle portion 15 is disposed so as to protrude outwardly through at least a portion of the lid portion 14. Correspondingly, an opening corresponding to the position and shape of the handle portion 15 is formed in the lid portion 14. At least one handle portion 15 is disposed on the wireless communication device 10, and may be disposed on the upper or lower part of the back surface of the wireless communication device 10 as shown in the figure. The handle portion 15 serves as a handle when the wireless communication device 10 is carried.

[0046] Furthermore, the handle portion 15 also serves as a guide for guiding the movement of the cover portion 14 when the cover portion 14 is closed. When the wireless communication device 10 is laid on its side so that its back faces the floor, the handle portion 15 also serves as a support base.

[0047] A fixing surface 151 for fixing the closed state when the lid portion 14 is closed is formed on the handle portion 15. After the lid portion 14 is closed following maintenance of the wireless communication device 10, the closed state of the lid portion 14 can be stably maintained by a screw connection, a magnetic connection, or the like between at least a part of the lid portion 14 and the fixing surface 151.

[0048] The handle 15 further includes a handle support 152 disposed within the cover 14 to support the position of the handle 15. One end of the handle support 152 engages with the main case 12 and / or the heat dissipation part 17. For example, one end of the handle support 152 is screwed to an engagement part formed on the heat dissipation part 17. A part of the handle support 152 is disposed between the cover 14 and the heat dissipation part 17, and the internal cables 16 can be arranged using the handle support. The cables 16 hung on the handle support 152 do not affect the arrangement of the wireless communication device 10 even if the wireless communication device 10 is arranged upright in the longitudinal direction. That is, in the past, the cables protruding from the bottom of the wireless communication device 10 were arranged within the cover 14 so as not to be visible from the outside, and the arrangement of the cables was fixed using the handle support 152.

[0049] FIG. 6 is a rear view of a wireless communication device according to an embodiment of the present disclosure.

[0050] Referring to FIG. 6, when the wireless communication device 10 is installed in an upright position in the longitudinal direction, the cable 16 moves downward due to the direction of gravity. Therefore, a separate support is required to fix the cable 16 in the cover 14 and the heat dissipation part 17. For convenience of explanation, the configuration of the cover 14 is omitted in FIG. 6. According to an embodiment of the present disclosure, the cable 16 is hung on the handle support part 152 of the handle part 15 disposed on the upper part of the wireless communication device 10, so that the space for organizing the cable 16 can be efficiently utilized. Furthermore, since the cable 16 is hung and fixed on the handle support part 152, it is possible to prevent the cable 16 from falling out when the cover 14 is opened for maintenance of the wireless communication device 10.

[0051] The above description is merely an illustrative example of the technical idea of ​​the present embodiment, and various modifications and variations are possible within the scope of the essential characteristics of the present embodiment, if one has ordinary knowledge in the technical field to which the present embodiment belongs. Therefore, the present embodiment is intended to explain, rather than limit, the technical idea of ​​the present embodiment, and the scope of the technical idea of ​​the present embodiment is not limited by such an embodiment. The scope of protection of the present embodiment should be interpreted according to the claims, and all technical ideas within the scope equivalent thereto should be interpreted as being included in the scope of the present embodiment.
