The first infusion pipe 75 and the second infusion pipe 76 are both provided with infusion connectors 8 at positions relative to the installation space 3, and the infusion connector 8 is detachably connected to the sealing cover 25.

[0022] refer to Figure 2 , Figure 3 The equipment assembly board 2 includes a board body 21, a liquid cooling tube 22 coiled and laid in the board body 21, two ends of the liquid cooling tube 22 extend out of the first side of the board body 21 and are respectively a liquid inlet end 221 and a liquid outlet end 222, the infusion connector 8 of the first infusion tube 75 is detachably connected and communicated with the liquid inlet end 221, and the infusion connector 8 of the second infusion tube 76 is detachably connected and communicated with the liquid outlet end 222, so that the first side of the board body 21 is positioned on the first infusion tube 75 and the second infusion tube 76. Preferably, the liquid inlet end 221 and the liquid outlet end 222 are both sleeve structures sleeved on the infusion connector 8.

[0023] The inner wall of the cabinet body 1 is provided with a support frame 16, which is arranged opposite to the liquid cooling assembly 7. The support frame 16 is provided with a support seat 17 at a position relative to the installation space 3. The support seat 17 is used to support the second side of the plate body 21, so that the second side of the plate body 21 is positioned on the support frame 16. The first infusion tube 75 and the second infusion tube 76 are both provided with a support portion 18 corresponding to the support seat 17, and the support portion 18 is located below the infusion connector 8, and the support portion 18 is used to support the first side of the plate body 21.

[0024] An elastic telescopic mechanism 19 is arranged above the support seat 17, and the telescopic end of the elastic telescopic mechanism 19 is pressed against the side of the plate body 21. The elastic telescopic mechanism 19 includes a slider 191 and an elastic member 192. The slider 191 is the telescopic end of the elastic telescopic mechanism 19.

When installing the equipment assembly plate 2, first insert the liquid inlet end 221 and the liquid outlet end 222 on the first side of the equipment assembly plate 2 into the corresponding two infusion connectors 8 respectively, and then press the second side of the equipment assembly plate 2 down to the inclined surface 23 of the slider 191. Under the guidance of the inclined surface 23, the slider 191 is pressed back and the elastic member 192 contracts so that the second side of the equipment assembly plate 2 is placed on the top surface of the corresponding support seat 17. Under the action of the elastic member 192, the slider 191 is pressed against the second side of the equipment assembly plate 2 to cooperate with the first infusion tube 75 and the second infusion tube 76 to clamp the equipment assembly plate 2 and ensure that the liquid inlet end 221 and the liquid outlet end 222 are reliably plugged with the two infusion connectors 8.

[0025] refer to Figure 2 , Figure 3 , Figure 4 The first cooling cover 73 and the second cooling cover 74 are both C-shaped. The first cooling cover 73 is fixedly arranged at the bottom of the air-cooling tube 5, and the second cooling cover 74 is slidably connected to the side wall of the air-cooling tube 5 away from the air-cooling hole 501. The first cooling cover 73 and the second cooling cover 74 are both provided with positioning grooves 10. The outer wall of the air-cooling tube 5 is provided with an outer convex strip 502 extending along its height direction. The positioning groove 10 and the outer convex strip 502 are matched with each other in a concave-convex manner, so as to position the orientation of the first cooling cover 73 and the second cooling cover 74 on the air-cooling tube 5, prevent the first cooling cover 73 and the second cooling cover 74 from interfering with the blowing operation of each air-cooling hole 501, and the cooperation between the positioning groove 10 of the second cooling cover 74 and the outer boss of the air-cooling tube 5 can also guide the sliding movement of the first cooling cover 73 on the air-cooling tube 5. A mounting plate 15 is provided between the lifting end of the lifting drive device 77 and the second cooling cover 74 . The lifting drive device 77 is a screw motor. The lifting drive device 77 adjusts the height position of the second cooling cover 74 through screw transmission.

[0026] The first cooling cover 73 and the second cooling cover 74 are both hollow inside and are provided with cooling pipes 9. The cooling pipes 9 in the first cooling cover 73 are connected to the water cooling box 71 and the lower end of the first infusion pipe 75, and the cooling pipes 9 in the second cooling cover 74 are connected to the second infusion pipe 76 and the water cooling box 71. A temperature sensor 4 is provided at a position of the inner wall of the cabinet body 1 relative to the installation space 3, and the temperature sensor 4 detects the temperature in the corresponding installation space 3. A position sensor 14 is also provided at a position of the inner wall of the cabinet body 1 relative to the installation space 3. The position sensor 14 can be a metal sensor, and the mounting plate 15 is made of induction metal. The mounting plate 15 and the position sensor 14 are inductively matched. A controller 24 is provided inside the cabinet body 1, and the temperature sensor 4, the air pump 6, the water pump 72, the lifting drive device 77, and the position sensor 14 are all connected to and controlled by the controller 24.

[0027] Under the action of the water pump 72, the coolant in the water cooling box 71 can flow through the first cooling cover 73, the first infusion pipe 75, the liquid cooling pipe 22, the second infusion pipe 76, and the second cooling cover 74 in sequence, and finally flow to the water cooling box 71 for circulation. In this process, the coolant flows through the first cooling cover 73 to pre-cool the bottom of the air cooling pipe 5. The cold air in the air cooling pipe 5 is output to each installation space 3 through each air cooling hole 501 through the air pump 6. The coolant flows through the liquid cooling pipe 22 to perform liquid cooling and heat dissipation treatment on the equipment assembly plate 2. The electromagnetic shielding cabinet performs liquid cooling and heat dissipation treatment on the equipment assembly plate 2 and the air cooling pipe 5 through the liquid cooling component 7, which effectively improves the heat dissipation efficiency.

[0028] When the information equipment in the installation space 3 generates more heat, the height position of the second cooling cover 74 is adjusted by the lifting drive device 77 so that the portion of the air-cooling pipe 5 corresponding to the installation space 3 with more severe heat corresponds to the second cooling cover 74, thereby performing secondary cooling on the gas inside the air-cooling pipe 5. The corresponding air-cooling holes 501 output cold air with lower temperature toward the installation space 3 with more severe heat, and can centrally cool the installation space 3 with higher temperature, thereby ensuring stable operation of the information equipment, effectively improving the heat dissipation capacity of the electromagnetic shielding cabinet, and ensuring the stability of the information equipment in the working environment.

[0029] refer to Figure 1 , Figure 5 , Figure 6The top or bottom surface of the plate body 21 is provided with a locking groove 28, and the inner wall of the cabinet door 11 is provided with a self-locking mechanism 29 that locks with the locking groove 28. The self-locking mechanism 29 includes a housing 291, a locking member 292, and a memory spring 293. The housing 291 is provided with a movable groove 30 for the locking member 292 to be slidably connected. The inner wall of the movable groove 30 is provided with a travel groove 31. The locking member 292 is provided with a travel block 32 that is slidably connected to the travel groove 31. The two ends of the memory spring 293 are respectively fixedly provided on the opposite sides of the travel groove 31 and the travel block 32. Under the action of the memory spring 293, the locking member 292 has a tendency to extend out of the housing 291, and the locking member 292 extends out of the housing 291, and the end of the locking member 292 forms a guide surface 33 that is inclined toward the plate body 21. When the cabinet door 11 is closed close to the cabinet body 1, the self-locking mechanism 29 is close to the corresponding equipment assembly plate 2, and the guide surface 33 abuts against the corresponding plate body 21. As the cabinet door 11 is closed, under the action of the guide surface 33, the plate body 21 tends to move the locking piece 292 back into the movable groove 30 until the movable groove 30 corresponds to the locking groove 28. The memory spring 293 recovers its deformation to drive the locking piece 292 to extend outward, and the end of the locking piece 292 is inserted into the locking groove 28. The inner groove wall of the locking groove 28 contacts and cooperates with the guide surface 33. The cabinet door 11 is locked on the cabinet body 1 through its respective locking mechanism 29 to prevent the cabinet door 11 from being opened due to external force.

[0030] The memory spring 293 is made of memory alloy. The heat generated when the information device is running is transferred to the self-locking mechanism 29. The memory spring 293 is subjected to too high a temperature, causing it to shrink. For example, the memory spring 293 is made of CuZnAl memory alloy wire, and its expansion and contraction temperature is 65°C-85°C. The free state, i.e., low temperature (room temperature), is 200mm, and the shortened state, i.e., high temperature (65°C-85°C), is 100mm. This is prior art and will not be described in detail here.

[0031] When the information equipment in the installation space 3 is overheated, the liquid cooling component 7 is used to perform liquid cooling on the equipment assembly plate 2 and the air cooling pipe 5. In this case, if the information equipment is still overheated but the overheating is not serious, the memory spring 293 contracts due to the heat to drive the locking member 292 to translate upward. When the temperature to which the memory spring 293 is subjected does not reach the expansion temperature, the translation stroke of the locking member 292 is small, and the locking member 292 is still located in the locking groove 28. The air cooling pipe 5 cooperates with the liquid cooling component 7 to cool the inner wall of the cabinet body 1 to ensure that the heat can be discharged when the cabinet door 11 is closed, while ensuring that the shielding function of the electromagnetic shielding cabinet is not affected.

[0032] Preferably, a temperature alarm 36 is provided on the cabinet door 11. When the temperature inside the cabinet body 1 exceeds a critical value set by the user, an alarm is issued to the outside world. The critical value may be the expansion and contraction temperature of the memory spring 293. The temperature alarm 36 is a prior art and will not be described in detail here.

[0033] When the information equipment in the installation space 3 is overheated, the liquid cooling component 7 is used to perform liquid cooling on the equipment assembly plate 2 and the air-cooling pipe 5. In this case, if the information equipment is still overheated and the overheating is serious, the memory spring 293 is heated and stretched to drive the locking member 292 to translate upward. The temperature to which the memory spring 293 is subjected reaches the expansion and contraction temperature, and the translation stroke of the locking member 292 is large, so that the locking member 292 is disengaged from the locking groove 28, and the cabinet door 11 is unlocked from the equipment assembly plate 2. At the same time, the temperature alarm 36 alarms and notifies the staff so that the staff can quickly open the cabinet door 11 in time to dissipate heat and cool down, and perform emergency operations such as cutting off the power supply. In addition, opening the cabinet door 11 helps air to quickly enter for heat exchange, thereby enhancing the cooling effect of the air-cooling pipe 5 and the liquid cooling component 7 and reducing the risk of equipment damage.

[0034] Preferably, the movable groove 30 passes through the shell 291, and the end of the locking piece 292 away from the plate body 21 extends to the outside of the shell 291. An electric push rod 34 is provided on the inner wall of the cabinet door 11 at a position relative to the self-locking mechanism 29. The push rod end of the electric push rod 34 is connected to the end of the locking piece 292 away from the plate body 21. A switch button 35 is provided on the outer wall of the cabinet door 11. The switch button 35 is electrically connected to the electric push rod 34 and is controlled by it. Before opening the cabinet door 11, the staff needs to press the switch button 35 to start the electric push rod 34. When the electric push rod 34 is started, it drives the locking piece 292 to overcome the memory spring 293 and move upward, thereby unlocking the self-locking mechanism 29 and the equipment assembly plate 2, preventing misoperation and preventing the staff from opening the cabinet door 11 at will due to carelessness or accidental touch.

[0035] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
