Description

TECHNICAL FIELD

[0001] The utility model relates to a case technical field, concretely is a portable waterproof case of natural heat dissipation type. BACKGROUND

[0002] Generally speaking, the existing cases in the current market are divided into two kinds, one is the case with active heat dissipation mode, and the other is the case with natural heat dissipation mode. The air-cooled case mainly relies on the rotation of the fan to promote air flow and heat dissipation. In order to achieve good heat dissipation capacity, the fan needs to use a fan with high air pressure and high speed. However, such a fan often makes a lot of noise. People working in this environment for a long time will cause many troubles. The fan runs at a high speed, which shortens the service life and increases the failure rate, which often brings great hidden dangers to the stable work of the case. The installation of the fan on the case means that the volume cannot be reduced, and space for the heat dissipation air duct also needs to be reserved, which will occupy a lot of space inside the case. It is not very friendly to users who have special requirements for small cases or internal space layout. The air-cooled case continuously inhales external air to dissipate heat, which also brings dust into the case. After a long time of use, the dust accumulates on the internal heat dissipation fins and fan blades, thereby affecting the heat dissipation efficiency. It also needs to waste manpower and material resources to clean regularly. The water-cooled case needs more space to arrange the heat exchanger and the heat dissipation waterway. Sometimes the external liquid cooling source needs to be considered to meet the use demand of high-power components. The case with such a heat dissipation mode cannot be used in outdoor scenes for a long time, and cannot be used in humid environments. People often consider the heat dissipation and maintenance aspects and prefer to use natural heat dissipation cases. Most of the natural heat dissipation cases on the market are made of plates, profiles and sheet metal splicing. There are too many assembly gaps. In order to meet the heat dissipation capacity, the volume is often made larger. The built-in heat dissipation device is provided with a large-area heat dissipation slot hole in the side wall of the case splicing plate to meet the natural heat dissipation. The case is heavy and not beautiful enough. The heat dissipation device is not compactly arranged, and the space utilization rate is low. CONTENT OF THE UTILITY MODEL

[0024] Example 1:

[0025] This embodiment provides a portable waterproof chassis with natural heat dissipation, specifically as follows: Figures 1-5 As shown, it includes: a housing, a module mounting bracket, and a fixing part. The housing includes a main frame 1, a power supply backplane mounting box 2, a power supply heat dissipation cover 3, a waterproof power amplifier module assembly 4, a front cover 5, and a module assembly interconnection backplane 13. The power supply backplane mounting box 2, the power supply heat dissipation cover 3, the waterproof power amplifier module assembly 4, and the front cover 5 are all mounted on the main frame 1. A docking cover 7 is installed on the waterproof power amplifier module assembly 4. The power supply module assembly 12 is placed in the power supply backplane mounting box 2. The main frame 1 is provided with multiple heat-conducting grooves. The module assembly interconnection backplane 13 is provided with positioning pins. The module mounting bracket is provided with guide sleeves that cooperate with the heat-conducting grooves. The module mounting bracket includes an interface module assembly box 17, a digital module assembly box 18, and an RF module assembly box 19. The RF module assembly... The component box 19 is provided with a lower cover plate 20 and an upper cover plate 21 for the radio frequency module assembly. The interface module assembly 9 is placed in the interface module assembly box 17. All external interfaces are built on the interface module assembly 9. All the interfaces of the chassis are arranged at the front of the chassis. Unlike traditional portable chassis, the radio frequency digital module assembly 11 is placed in the digital module assembly box 18 and the radio frequency module assembly box 19. Multiple fixing parts are respectively installed on the interface module assembly box 17, the digital module assembly box 18, and the radio frequency module assembly box 19. The fixing parts include a compression unit and an expansion unit. The compression unit is used to compress the expansion unit, so that the expansion unit expands and abuts against the box body, thereby achieving relative fixation between the interface module assembly box 17, the digital module assembly box 18, the radio frequency module assembly box 19 and the chassis.

[0026] During assembly, firstly, the conductive waterproof strip 14 with adhesive backing is embedded into the dedicated mounting slots of each component. The waterproof power amplifier module 4 is guided and connected to the main frame 1 through the positioning pin on the main frame 1. Then, the screw holes are aligned and tightened with screws. Similarly, for the RF module component box 19, the shielding cotton strip is first embedded into the slot, and then the lower cover plate 20 and the upper cover plate 21 of the RF module component are aligned with the RF module component box 19 and tightened with screws. When assembling the module mounting bracket with the chassis, simply push the module mounting bracket along the heat-conducting slide of the chassis until the module mounting bracket and the positioning pin on the module component interconnection backplate 13 are engaged and successfully connected. Then, the extrusion unit is used to extrude the expansion unit, causing the expansion unit to expand and contact the chassis. Under the action of friction, the module mounting bracket will not easily shake in the chassis, ensuring the stability of each module component. Then, the front cover 5, the power supply backplate mounting box 2, and the power supply heat dissipation cover 3 are installed in sequence.

[0027] All metal parts are made of high-strength anti-rust aluminum alloy material, and are designed according to the structure, material mechanics and thermal characteristics, processed by high-precision machine tools, with accurate size, high strength, and high surface hardness after point oxidation treatment, not easy to damage, all exposed surfaces are sprayed with magnetic paint for protection, taking into account the conductivity while the appearance is elegant and atmospheric, the overall waterproof level is IP65, and the performance is not affected in extreme environments such as concentrated salt spray, high humidity, high altitude and drought. There are no excess flexible cables inside the case, and most of the overall assembly uses a plug-in and buckle method to prevent the impact of excess cable swinging on internal components during transportation. The case and the module mounting rack are integrated, and there is no stress interference to the internal components to cause disassembly. The front end cover 5 uses high-heat-resistant, high-strength, acid and alkali-resistant, IP65 waterproof level connectors, and the mechanical clamping performance is excellent, making it easy and fast to operate and connect.

[0028] The overall heat dissipation of the case uses natural conduction cooling and natural radiation heat dissipation. The heat transfer of each functional module is from the heat generating chip to the heat conducting silica gel pad, then to the cavity of each module component box body, then to the heat dissipation unit and heat conducting sliding groove, and then to the case shell, and finally to the surrounding environment for natural radiation heat dissipation. The heat accumulation is small, the heat transfer path is short and fast, and compared with the traditional air transfer inside the case, the heat accumulation is greatly reduced. Especially in outdoor use, in the external variable environment, the wind and rain, the case becomes a kind of air-cooled and water-cooled case, and the performance is greatly improved. The natural cooling is achieved by the main heat transfer of each module component box cavity, that is, the high-thermal-conductivity silica gel pad is filled between each heat generating device or heat generating surface and the heat conducting cavity to enhance the heat transfer capacity and provide certain buffering capacity for the heat dissipation components.

[0029] Through the above arrangement, the stability of each module component placed on the module mounting rack in the case is improved, and at the same time, the heat conduction path is shortened and the heat conduction speed is improved, so that the case has better heat dissipation effect. The module mounting rack is used to carry each module component box, the overall assembly is convenient and flexible, the space utilization rate is high, the overall volume is small, and the handle is arranged on the waterproof power amplifier module component to realize the portable purpose.

[0030] Embodiment 2:

[0031] This embodiment further extends the fixed part based on the above embodiment, as shown in Figure 3 The extrusion unit includes a puller 15, and the expansion unit includes a plurality of linearly arranged wedge-shaped expansion locking blocks 16. The wedge-shaped expansion locking blocks 16 are made of soft rubber or other materials that are easy to deform.

[0032] The puller 15 does not compress the wedge-shaped expansion locking block 16 in its initial state. At this time, pulling the puller 15 by hand can easily pull out the interface module component box 17, digital module component box 18, and radio frequency module component box 19 from the module mounting bracket. When the puller 15 is moved and fixed, it will compress the wedge-shaped expansion locking block 16. At this time, the wedge-shaped expansion locking block 16 is deformed by force and compresses the heat-conducting groove, so that the interface module component box 17, digital module component box 18, and radio frequency module component box 19 will not easily shake.

[0033] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0036] When the puller 15 squeezes the wedge-shaped expansion locking block 16, the adjacent wedge-shaped expansion locking blocks 16 will slide relative to each other, thereby further moving and squeezing the heat-conducting groove, further increasing the squeezing contact area, thereby improving the heat transfer speed between the wedge-shaped expansion locking block 16 and the heat-conducting groove, and further improving the heat dissipation effect of the chassis.

[0037] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0039] This embodiment further extends the above embodiment, specifically as follows: Figures 4-5 As shown, the main frame 1, power supply heat dissipation cover 3, and waterproof power amplifier module assembly 4 are all equipped with heat-conducting fins. By providing heat-conducting fins on multiple sides of the chassis, the heat dissipation effect can be further improved when heat is transferred from the wedge-shaped expansion locking block 16 to the chassis.

[0040] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0041] Example 5:

[0042] This embodiment further extends the above embodiment, specifically as follows: Figure 1 As shown, a debugging port is provided on the front cover 5, a debugging end cover 6 is installed on the debugging port, and a device nameplate 8 is provided on the debugging end cover 6.

[0043] By setting the debugging end cover 6 on the front cover 5, the convenience of function upgrades, product debugging and other operations is greatly increased.

[0044] Other parts of this embodiment are the same as the above-described embodiments, and will not be described again.

[0045] Embodiment 6:

[0046] This embodiment is further extended on the basis of the above-described embodiments, and specifically as shown in Figure 4 The corner guards 10 are installed on the corners of the box body.
