[0003] Mine explosion-proof control boxes are a crucial component of mining equipment, used to control its operation. However, due to the harsh and high temperatures of mining environments, high temperatures can easily build up inside the control box, impacting the equipment's normal operation and service life. Currently, there are cooling devices on the market, but most are external and require connection to the control box via pipes or other connections. This makes installation and maintenance difficult, and the cooling effect is limited. Therefore, effectively reducing the temperature inside the control box to ensure proper operation of the equipment remains a pressing issue in the field of mining equipment technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example:

[0027] like Figures 1 to 6 As shown, a built-in cooling device for a mine explosion-proof control box includes a control box body 3, heat absorption components 2 are provided on the left and right sides of the inner wall of the control box body 3, an energy storage box 5 is installed on the top of the inner wall of the control box, the energy storage box 5 is filled with heat absorption filler 11, and multiple groups of plug-in copper tubes 9 are provided on the left and right sides of the energy storage box 5. Multiple groups of heat-conducting rods 10 are evenly inserted in the heat-absorbing filler 11. A radiator 7 is fixed on the upper side of the control box body 3, and the upper end of the heat-conducting rod 10 passes through the control box body 3 and is welded to the radiator 7. This design solves the problem in the prior art that due to the harsh mining environment and high temperature, high temperature is easily generated in the control box, which affects the normal operation and service life of the equipment. At present, most cooling devices on the market are external and need to be connected to the control box through pipes and other connection methods. They are inconvenient to install and maintain, and the cooling effect is limited.

[0028] The heat absorption assembly 2 consists of multiple groups of heat pipes 21 and a heat absorption sheet 22. The bottom surface of the heat absorption sheet 22 is coated with resin and bonded to the inner wall of the control box 3. This design ensures good thermal contact between the heat absorption sheet 22 and the control box 3, thereby quickly absorbing heat from the box. The resin not only provides good adhesion but also has certain thermal conductivity, further enhancing the heat transfer effect. Multiple groups of heat pipes 21 are evenly arranged inside the heat absorption sheet 22, and the upper ends of the heat pipes 21 are connected to the plug-in copper tube 9. The heat pipe 21 is a highly efficient heat conduction element that transfers heat by converting the internal working medium into a liquid and gaseous state during the phase change process. The heat in the heat absorption sheet 22 can be absorbed by the heat pipe 21. The design facilitates the absorption of heat from the control box 3 by the heat absorption assembly 2, reducing the accumulation of heat inside the control box 3 and effectively lowering the temperature inside the control box 3.

[0029] Heat sink 22 is made of thin copper sheet, an excellent thermal conductor that absorbs and transfers heat quickly and efficiently. This design provides a large heat exchange area, improving heat absorption efficiency. Furthermore, the sheet contains a cavity filled with coolant, which absorbs a significant amount of heat and quickly transfers it to other parts of the sheet. This design, combining copper's high thermal conductivity with the coolant's efficient heat absorption, allows heat sink 22 to quickly and effectively absorb heat from within the control box, ensuring the proper functioning of the equipment within.

[0030] The thermal filler is alumina powder, which has high thermal conductivity and excellent thermal stability. It can quickly absorb the heat transferred from the heat pipe 21 to the energy storage box 5, store the heat, and transfer the heat through the thermal rod 10.

[0031] The radiator 7 is composed of a heat sink 71, heat dissipation holes 72 and a base plate 73. The base plate 73 is installed on the top of the control box 3 by screws. A plurality of heat sinks 71 are evenly fixed on the base plate 73. The heat sink 71 greatly increases the heat dissipation area and improves the heat dissipation efficiency. In addition, a plurality of heat dissipation holes 72 are evenly opened inside the heat sink 71. The holes not only increase the heat dissipation area, but also help air circulation, so that heat can be transferred to the air more quickly. An arc-shaped groove is opened at the center of the upper end face of the heat sink 71. This design helps to break the laminar state of the air on the surface of the heat sink 71, forming turbulence, thereby enhancing the convection heat dissipation effect, while promoting air flow and improving heat dissipation efficiency. The heat sink 7 can effectively dissipate the heat generated inside the control box to the external environment, which is beneficial to the cooling and heat dissipation inside the control box 3.

[0032] A dust cover 1 is provided on the upper side cover of the radiator 7. The dust cover 1 can form a protective layer for the radiator 7 to prevent dust particles in the air from adhering to the radiator 7 and affecting its heat dissipation effect. A heat dissipation port is provided on the right side of the dust cover 1, and a heat dissipation fan 8 is installed on the inside of the heat dissipation port. The heat dissipation fan 8 can generate forced convection to accelerate the air flow, thereby taking away the heat on the radiator 7 and improving the heat dissipation efficiency. An exhaust pipe 4 is connected to the right side of the heat dissipation port. The function of the exhaust pipe 4 is to guide the hot air blown out by the cooling fan 8 to the external environment to prevent the hot air from flowing back and circulating inside the dust cover 1, and a dustproof net 6 is provided at the lower end of the exhaust pipe 4. The dustproof net 6 can prevent dust and particulate matter in the external environment from entering the dust cover 1 through the exhaust pipe 4 and affecting the normal operation of the radiator 7.

[0033] The working principle of this built-in cooling device for a mine explosion-proof control box is as follows: In actual use, the upper end of the heat pipe 21 on the heat absorbing sheet 22 is first connected to the plug-in copper tube 9. The heat absorbing sheet 22 is then affixed to the inner wall of the control box 3 using resin. When the temperature inside the control box 3 rises, the heat absorption assembly 2 inside the control box 3 begins to operate. The heat absorbing sheet 22, made of thin copper sheet, can quickly and efficiently absorb the heat generated within the box. The coolant inside the heat absorbing sheet 22 further enhances the heat absorption effect, allowing heat to be absorbed and transferred to the heat pipe 21 more quickly. The heat pipe 21 then transfers the absorbed heat to the alumina powder filler in the energy storage box 5 through the plug-in copper tube 9. Alumina powder has high thermal conductivity and excellent thermal stability, which can quickly absorb and store this heat. The heat conducting rod 10 inside the energy storage box 5 then transfers the heat from the alumina powder to the heat sink 7. Then the cooling fan 8 starts to generate forced convection, accelerates the air flow, speeds up the heat dissipation efficiency of the radiator 7, and guides the hot air to the external environment through the exhaust pipe 4 to avoid the backflow of the hot air.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
