[0012] Furthermore, the second limiting plate is detachably connected to the heat conducting plate.

[0013] By adopting the above technical solution, main control boards of different sizes can be tested, thereby improving the versatility and utilization rate of the device.

[0014] Furthermore, the heat conducting plate is a copper plate.

[0020] Furthermore, the nozzle is in a trumpet shape.

[0021] By adopting the above technical solution, the carbon dioxide fire extinguishing agent can be evenly sprayed to the fire source area with a large coverage area, reducing the oxygen concentration around the fire source to achieve fire extinguishing, while protecting undamaged electronic components.

[0022] In summary, compared with the prior art, the utility model has the following beneficial effects:

When the staff is not on site, the smoke alarm activates the valve of the carbon dioxide fire extinguishing device, and the liquid carbon dioxide is quickly converted into gaseous state and sprayed out at high speed. The released high-pressure gaseous carbon dioxide quickly spreads around the fire source and covers the surface of the burning object, thereby achieving the effect of extinguishing the fire. At the same time, carbon dioxide can absorb a large amount of heat when released, and assists in fire extinguishing through cooling. It ensures rapid heat dissipation and fire extinguishing of the main control board, and protects the safety of the staff and the working environment. BRIEF DESCRIPTION OF THE DRAWINGS
