[0089] Two conical flanges 401, a groove 402, and several bolt holes 403 are provided on the retaining ring 400; the two conical flanges 401 are matched with the No. 1 conical flange 101 and the No. 2 conical flange 705 of the cabin 100 respectively; bolts 500 are installed in the bolt holes 403 to splice the retaining ring 400 into a full circle.

[0090] The heat dissipation tube 600 is provided with an external thread 601, a sealing gasket 602 and a bent section 603; the external thread 601 matches the refrigerant diffusion hole 704 on the end cover 700; the tail end of the heat dissipation tube 600 is closed to prevent refrigerant leakage; the sealing gasket 602 fits with the outer surface 706 of the end cover to prevent refrigerant leakage; the bent section 603 is used to increase the heat dissipation area and improve the heat dissipation efficiency.

[0091] A number of through-holes 702, a number of threaded holes 703, a refrigerant diffusion hole 704 and a No. 2 conical flange 705 are provided on the end cover 700; the through-holes 702 are used to install cable through-holes to realize the transmission of power and signals of the electronic equipment 300 in the cabin; the threaded holes 703 match the heat exchange plate mounting holes 202; the refrigerant diffusion hole 704 cooperates with the No. 2 sealing ring 204 at one end of the inner surface 701 of the end cover, and cooperates with the external thread 601 and the sealing gasket 602 at one end of the outer surface 706 of the end cover to realize the diffusion and reflux of the refrigerant from the heat exchange plate 200 to the heat dissipation pipe 600.

[0098] When the electronic device 300 generates heat, the heat is transferred to the refrigerant through the heat exchange plate 200, causing the refrigerant to vaporize. The gaseous refrigerant diffuses to the heat pipe 600 outside the electronic compartment through the refrigerant diffusion port 203. The gaseous refrigerant transfers the heat to the outside in the heat pipe 600, turns back into liquid, and flows back to the heat exchange plate 200. Through the continuous vaporization and liquefaction process of the refrigerant, the function of exporting the heat in the electronic compartment to the outside is achieved.
