Description

Technical Field

[0001] This utility model relates to the field of communication base station system technology, and in particular to a rainproof and dustproof heat dissipation structure and an outdoor communication cabinet. Background Technology

[0002] Outdoor communication cabinets are specialized cabinets that provide a stable and reliable outdoor physical working environment for wireless communication base stations (such as 4G and 5G sites) and wired network equipment. They are widely deployed in various open or semi-open environments such as along highways, in mountainous areas, and on rooftop platforms. They typically integrate key devices such as communication transmission equipment, power modules, batteries, and temperature control systems. Due to long-term exposure to the natural environment, these cabinets not only need to cope with seasonal temperature changes but also face complex climatic conditions such as rain, snow, and dust.

[0003] Currently, common outdoor communication cabinets still suffer from several prevalent structural design flaws. Regarding heat dissipation, most traditional cabinets rely on ventilation holes or louvers for natural air cooling. While these openings provide some cooling, they are highly susceptible to rainwater ingress or leakage, leading to short circuits and corrosion of internal electrical components, severely impacting equipment safety and lifespan. Furthermore, during ventilation, dust and suspended particles from the outside air enter the cabinet and accumulate, not only covering the equipment surface and affecting heat dissipation efficiency but also potentially causing circuit board corrosion or poor contact, further threatening system reliability.

[0004] To enhance protection, some products adopt a sealed design to improve dust and water resistance. However, this significantly weakens the heat dissipation performance of the cabinet, which can easily cause internal temperature to rise, especially in hot seasons, leading to a decline in the performance of electronic equipment or even shutdown due to overheating. Utility Model Content

[0005] In view of the problem that outdoor communication cabinet heat dissipation structures are prone to dust and water ingress in the above-mentioned or existing technologies, this utility model is proposed.

[0006] Therefore, the purpose of this invention is to provide a heat dissipation structure that is rainproof and dustproof.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rainproof and dustproof heat dissipation structure, including an air inlet and an air outlet set on the cabinet, wherein air enters the cabinet through the air inlet and is discharged through the air outlet, and the openings of the air inlet and the air outlet are oriented to prevent rainwater from flowing in.

[0011] As a preferred embodiment of the rainproof and dustproof heat dissipation structure of this utility model, the top plate assembly further includes a cover plate, the cover plate has receiving grooves on both sides, the receiving grooves protrude from the side wall of the cabinet, and the bottom surface of the receiving grooves is provided with exhaust holes.

[0012] As a preferred embodiment of the rainproof and dustproof heat dissipation structure of this utility model, wherein: the air inlet and the air inlet hole constitute the air inlet end; the exhaust port, the exhaust fan and the exhaust hole constitute the air outlet end.

[0013] The beneficial effects of this rainproof and dustproof heat dissipation structure are as follows: By installing exhaust vents on the bottom surface of the cover, rainwater cannot enter the vents during outdoor rainy weather due to gravity and wind direction, effectively preventing rainwater from entering the cabinet and protecting electrical components from damage. The outer cover of the air inlet provides double protection against rain; even if a small amount of rainwater splashes near the air inlet, the cover can block it, ensuring that rainwater does not enter the cabinet through the air inlet.

[0014] In view of the problem of poor heat dissipation in outdoor communication cabinets in the above or existing technologies, this utility model is proposed.

[0015] Therefore, another objective of this utility model is to provide an outdoor communication cabinet with a heat dissipation structure that is rainproof and dustproof.

[0016] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an outdoor communication cabinet with a rainproof and dustproof heat dissipation structure, comprising several sets of air supply channels, wherein the several sets of air supply channels are arranged inside the cabinet and connected between the rainproof and dustproof heat dissipation structures, and air enters the air supply channels through the air inlet of the rainproof and dustproof heat dissipation structure and then gathers at the air outlet of the rainproof and dustproof heat dissipation structure and is discharged.

[0017] As a preferred embodiment of the outdoor communication cabinet with a rainproof and dustproof heat dissipation structure of this utility model, the cabinet is provided with a shelf, which is symmetrically arranged and has a gap reserved around its perimeter with the inner wall of the cabinet; shelf panels are arranged longitudinally along the shelf, and two electrical modules are placed on each pair of opposite shelf panels, with a pre-set gap between the two electrical modules.

[0031] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0032] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0033] Reference Figure 1 The first embodiment of this utility model provides a rainproof and dustproof heat dissipation structure, which is a special device for providing an outdoor physical working environment for wireless communication base stations or wired network sites.

[0034] Specifically, it includes an air inlet N1 and an air outlet N2 installed on the cabinet 100. Air enters the cabinet 100 through the air inlet N1 and is discharged through the air outlet N2. The continuous flow of air through the cabinet 100 cools down the various electrical devices inside the cabinet 100.

[0035] Reference Figures 2-7The second embodiment of this utility model differs from the previous embodiment in that the cabinet 100 in this embodiment includes a bottom plate assembly 101, which is configured as a shell and is formed by riveting metal plates. An array of air inlets 101a is provided on its side wall 101b. In this embodiment, two sets of air inlets 101a are opened on each side wall, and each set includes six air inlets 101a, so that air can enter the cabinet 100 evenly from the bottom of the cabinet 100.

[0036] Furthermore, the top plate of the base plate assembly 101 serves as the base plate 101c of the cabinet 100, and an air inlet hole 101d is provided on it. In this embodiment, the air inlet holes 101d are set in two groups, symmetrically arranged along the length of the base plate 101c. The number of air inlet holes 101d in each group is adjusted according to the overall ventilation and cooling needs of the cabinet 100. Preferably, a filter screen M is installed on the top surface of the air inlet hole 101d. The filter screen M has a pore size of 1 to 5 micrometers. Installing the filter screen M on the top surface of the air inlet hole 101d can effectively prevent dust from entering the cabinet 100 through the air inlet hole 101d. The filter screen M is detachably connected to the base plate 101c. After a period of use, the filter screen M is easy for staff to replace or clean, ensuring the filtration effect.

[0037] Furthermore, each air inlet 101a is provided with a cover plate 101e, which protrudes from the air inlet 101a and completely covers the air inlet 101a to prevent rainwater from entering the base plate assembly 101 through the air inlet 101a; the lower part of the cover plate 101e has a downward opening notch, through which air can enter the base plate assembly 101.

[0038] It should be noted that the air inlet 101a and the cover plate 101e can be integrally formed by punching holes in a metal plate.

[0039] In addition, the cabinet 100 also includes a top panel assembly 102, which includes a top panel 102a, which also serves as the top panel of the cabinet 100.

[0040] The top plate 102a has an exhaust port 102b. In this embodiment, there are two exhaust ports 102b, which are symmetrically distributed along the width direction of the top plate 102a.

[0041] An exhaust fan 102c is installed on the bottom surface of the exhaust port 102b. The exhaust fan 102c runs continuously, so that the air filtered through the air inlet vent 101d forms a stable air circulation inside the cabinet, and removes the heat generated by the equipment in a timely manner.

[0042] A filter screen M is installed on the top surface of the exhaust port 102b. The filter screen M has a pore size of 1 to 5 micrometers, which can prevent dust from entering the cabinet 100 through the exhaust port 102b when the cover plate 102d is removed for cleaning. The filter screen M is detachably connected to the top plate 102a, which makes it easy for staff to replace or clean the filter screen M after a period of use, thus ensuring the filtration effect.

[0043] The top panel assembly 102 also includes a cover plate 102d, which covers and encloses the top of the cabinet 100. A buffer space is formed between the cover plate 102d and the top panel 102a to buffer the hot air discharged from the cabinet 100 by the exhaust fan 102c. Since hot air continuously fills the buffer space, it is discharged along the exhaust vent 102f. The cover plate 102d has receiving grooves 102e on both sides, which protrude from the side wall of the cabinet 100. The bottom surface of the receiving grooves 102e has an exhaust vent 102f to discharge the hot air brought by the exhaust fan 102c. The downward orientation of the exhaust vent 102f effectively prevents rainwater from flowing into the cabinet 100.

[0044] Furthermore, to prevent rainwater from remaining on the cover plate 102d, the top surface of the receiving trough 102e is inclined downwards to form a guide surface 102 so as to guide the rainwater to flow away.

[0045] Specifically, the cover plate 102d is formed by bending a metal plate; after the metal plate is cut, holes are punched at both ends, and then it is bent downwards at an angle, then bent perpendicular to the ground, and finally bent inwards simultaneously to form a receiving groove 102e; the other two ends are bent perpendicular to the ground and welded to the two ends of the receiving groove 102e, as shown in the figure. Figure 7 .

[0046] Preferably, a plurality of connecting posts 102g are welded at equal intervals to the bottom surface of the cover plate 102d. The connecting posts 102g are adapted to the connecting pipes 102h welded to the top surface of the top plate 102a. When the cover plate 102d is placed on the top plate 102a, the connecting posts 102g are inserted into the connecting pipes 102h to facilitate the positioning and fixed connection between the cover plate 102d and the top plate 102a. Furthermore, a support rib 102i is riveted to the top surface of the top plate 102a. The support ribs 102i are distributed on both sides of the top plate 102a, and the cross-section of the support ribs 102i is Z-shaped. This is used to support the cover plate 102d to prevent the cover plate 102d from deforming and affecting the buffer space between the cover plate 102d and the top plate 102a.

[0047] Understandably, the air inlet 101a and the air inlet vent 101d constitute the air inlet end N1; the exhaust port 102b, the exhaust fan 102c, and the exhaust vent 102f constitute the air outlet end N2. The air inlet end N1 is located at the bottom of the cabinet 100, and the air outlet end N2 is located at the top of the cabinet 100.

[0048] Reference Figure 8 and 9 The third embodiment of this utility model provides an outdoor communication cabinet with a rainproof and dustproof heat dissipation structure. It includes the heat dissipation structure described in the previous embodiment, and further includes several sets of air supply channels N. These air supply channels N are disposed within the cabinet body 100 and connected to the rainproof and dustproof heat dissipation structure. Air enters the air supply channels N through the air inlet N1 of the rainproof and dustproof heat dissipation structure and then collects at the air outlet N2 of the structure before being discharged. The air supply channels N are arranged in an orderly manner within the cabinet body 100, effectively carrying away hot air from inside the cabinet body 100.

[0049] In this embodiment, a shelf 200 is provided inside the cabinet 100. The shelf 200 is symmetrically arranged, and a gap is reserved between its four sides and the inner wall of the cabinet 100; that is, the four sides of the shelf 200 maintain a predetermined distance from the inner wall of the cabinet 100.

[0050] Shelf 200 is bolted with shelf 201. Shelf 201 is installed at equal intervals along the longitudinal direction of shelf 200. Two electrical modules 300 are placed on each pair of opposite shelf 201. A gap 301 is preset between the two electrical modules 300.

[0051] When the exhaust fan 102c exhausts air, air enters the cabinet 100 from the air inlet N1 and flows along the gaps between the electrical modules 300 and the gaps between the electrical modules 300 and the side wall of the cabinet 100 to the air outlet N2. After merging in the buffer space of the cover plate 102d, it is discharged; that is, the gaps between the electrical modules 300 and the gaps between the electrical modules 300 and the side wall of the cabinet 100 form the air supply channel N.

[0052] Preferably, the cabinet 100 also has a door panel 103, on which a DC air conditioner 104 is installed. The air outlet of the DC air conditioner 104 is aligned with the inverter in the electrical module 300. Since the inverter in the electrical module 300 generates the most heat inside the cabinet 100, the DC air conditioner 104 is installed facing the inverter.

[0053] When the temperature and humidity controller 102k installed on the top surface of the top plate 102a senses that the temperature and humidity inside the cabinet 100 exceed the threshold, it activates the DC air conditioner 104. The temperature and humidity controller 102k detects that environmental parameters exceed the preset suitable range and quickly coordinates with the DC air conditioner to adjust them. When the temperature inside the cabinet is too high, the DC air conditioner activates its cooling function to lower the temperature; when the humidity is too high, the DC air conditioner can also reduce the humidity through the corresponding mode, ensuring that the electronic equipment inside the cabinet is always in a stable working environment.

[0054] The working process of this utility model is described below: First, air enters the cabinet 100 from the air inlet N1. When it passes through the filter M, dust and other impurities in the air are intercepted.

[0055] The continuous operation of the exhaust fan 102c promotes a stable air circulation inside the cabinet after filtration, and promptly removes the heat generated by the equipment from the cabinet 100.

[0056] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
