Description

Technical Field

[0001] The present invention relates to the field of heat dissipation technology of a 5G radio frequency remote unit for mining, and in particular to a heat dissipation device and equipment for a flameproof and intrinsically safe 5G radio frequency remote unit for mining. Background Art

[0002] At present, 5G (5th generation mobile networks, fifth generation mobile communication technology) systems are gradually being applied to the coal industry. 5G equipment cannot be directly used in coal mines, and must meet the requirements of the national standard GB3836.1-2010 "Explosive Environment", that is, 5G equipment must be explosion-proof. The 5G radio frequency remote unit for mining generates huge heat, which can reach hundreds of watts. Therefore, it is impossible to use the intrinsically safe explosion-proof type with a power range of 10w (watt) to 20w, and the flameproof explosion-proof type must be used. The flameproof explosion-proof type requires that the flameproof cavity must reach a certain strength, and the thickness of the steel plate generally ranges from 10mm (millimeter) to 15mm; at the same time, the space of the flameproof cavity needs to be closed, which puts higher requirements on the heat dissipation of the 5G radio frequency remote unit for mining.

[0003] See also Figure 1 , Figure 1 This is a structural diagram of an embodiment of a heat dissipation solution for an existing 5G radio remote unit for mining. Figure 1 As shown in the figure, the existing heat dissipation solution of the 5G RF remote unit for mining is that the explosion-proof type of the 5G RF remote unit for mining basically adopts the method of adding a flameproof cavity, that is, the 5G RF remote unit for mining itself is basically not modified, and is directly placed in a flameproof cavity that meets the explosion-proof requirements. The heat dissipation method adopted is natural heat dissipation by air convection. The heat flow generated by the 5G RF remote unit for mining is transferred to the flameproof cavity through the air in the closed flameproof cavity. The material of the flameproof cavity is steel plate with a thickness generally ranging from 10mm to 15mm, and then transferred to the external air, finally achieving the heat dissipation effect.

[0004] However, the inventors have found that the prior art has at least the following problems:

[0005] The existing cooling solution for 5G RF remote units for mining uses natural heat dissipation through air convection, which usually has low heat dissipation efficiency and slow heat flow transfer. In addition, due to the use of natural heat dissipation through air convection, the volume of the explosion-proof cavity is usually large, and the application scenarios of the 5G RF remote units for mining are limited. They cannot be deployed in important locations such as underground comprehensive mining working faces and hydraulic supports in coal mines, which greatly affects the support of 5G technology for the intelligentization of coal mines. At the same time, the volume and weight of the explosion-proof cavity are large, which makes it inconvenient to transport, install and maintain the 5G RF remote units for mining in coal mines, increasing construction and operation and maintenance costs. Summary of the invention

[0006] In view of this, the purpose of the present invention is to propose a heat dissipation device and equipment for a flameproof and intrinsically safe 5G radio frequency remote unit for mining, which can achieve efficient heat flow transfer, reduce the volume and weight of the flameproof cavity, improve the applicability of the 5G radio frequency remote unit for mining in underground coal mines, and reduce construction and operation and maintenance costs.

[0008] Wherein, the heat dissipation substrate is made of copper.

[0009] The flameproof cavity comprises a box and a temperature controller. The temperature controller is installed inside the box, and the temperature controller maintains the air in the box at a preset temperature environment.

[0010] The flameproof cavity comprises a box and a respirator. The respirator is installed inside the box, and a connecting pipe is arranged outside the box. The connecting pipe is connected to the respirator, and the respirator eliminates moisture from the air in the box.

[0011] Wherein, the heat dissipation substrate comprises a heat-conducting shell and a phase-change heat dissipation substrate, and the heat-conducting shell covers the phase-change heat dissipation substrate.

[0015] It can be found that in the above scheme, the heat dissipation device for the explosion-proof and intrinsically safe mining 5G radio frequency remote unit may include a flameproof cavity and a mining 5G radio frequency remote unit, the flameproof cavity is sealed, the mining 5G radio frequency remote unit is arranged in the flameproof cavity, a heat dissipation substrate is arranged on the flameproof cavity, the inner surface of the heat dissipation substrate is arranged with corresponding grooves, the outer surface of the heat dissipation substrate is arranged with heat dissipation teeth, the mining 5G radio frequency remote unit is arranged with a circuit board, the circuit board is arranged with a chip, the chip is fully fitted with the corresponding groove, and the chip is fully fitted with the corresponding groove. An insulating heat-conductive material is arranged at the reserved position which fits with the groove. When the mining 5G radio frequency remote unit generates heat, the heat is conducted to the inner surface of the heat dissipation substrate arranged on the fully-fitting explosion-proof cavity through the insulating heat-conductive material. The heat flow of the generated heat is quickly conducted to the outer surface of the heat dissipation substrate arranged on the explosion-proof cavity, and is conducted to the outside air through the outer surface of the heat dissipation substrate and the heat dissipation teeth, thereby realizing efficient heat flow transfer, reducing the volume and weight of the explosion-proof cavity, improving the applicability of the mining 5G radio frequency remote unit in underground coal mines, and reducing the construction and operation and maintenance costs.

[0016] Furthermore, in the above solution, the heat dissipation substrate is made of copper. This has the advantage that copper has excellent thermal conductivity and can effectively improve the transfer of heat flow and heat dissipation.

[0017] Furthermore, the above scheme, owing to the heat dissipation method of heat conduction, improves the 5G RF remote unit for mining and the inner surface of the explosion-proof cavity, so that the chip on the circuit board of the 5G RF remote unit for mining is fully bonded to the inner surface of the explosion-proof cavity. In order to prevent the contact with the inner surface of the explosion-proof cavity and cause the electronic device to conduct electricity, corresponding space needs to be reserved, and heat is conducted by insulating thermally conductive materials, so that the heat generated by the 5G RF remote unit for mining is quickly transferred to the explosion-proof cavity, and the efficiency of the heat conduction method is greatly improved.

[0018] Furthermore, the above scheme can set heat dissipation teeth on the outer surface of the heat dissipation substrate of the explosion-proof cavity, which can improve the heat flow conduction speed between the explosion-proof cavity and the external air, further improve the overall heat dissipation efficiency of the mining 5G radio frequency remote unit, and maximize the heat dissipation area while minimizing the volume of the explosion-proof cavity.

The temperature controller maintains the air in the box body at a preset temperature environment. The advantage of this is that the air in the explosion-proof cavity can be maintained at a constant temperature state in a preset temperature environment, which can effectively extend the service life of the electrical equipment in the explosion-proof cavity.

[0021] Furthermore, in the above scheme, the explosion-proof cavity may include a box body and a respirator. The respirator is installed on the inner side of the box body, and a connecting pipe is arranged on the outer side of the box body. The connecting pipe is connected to the respirator.
