[0031] A protective shell 205 is fixedly installed on the outer wall of the middle part of the cooling pipe 201. The inner side of the protective shell 205 is fixedly installed with a liquid guide pipe 207. The two ends of the outer wall of the liquid guide pipe 207 extend towards the outer wall of the protective shell 205, and connection ports 208 are opened at both ends of the liquid guide pipe 207. As Figure 4 shown, the protective shell 205 shapes and supports the liquid guide pipe 207;

[0032] The end cover main body 1 includes a cover body 101. A sealing groove 102 is opened on the side of the outer wall of the cover body 101, and mounting holes 103 are opened around the surface of the cover body 101. As Figure 1 shown, a sealing structure is installed in the sealing groove 102 to improve the sealing performance between the end cover main body 1 and the carbon dioxide compressor body;

[0033] An exhaust port 105 is fixedly installed in the middle of the cover body 101. Reinforcing ribs 104 are fixedly connected to the periphery of the side wall of the exhaust port 105. The ends of each reinforcing rib 104 away from the exhaust port 105 extend outwards, and the inner sides of each reinforcing rib 104 are fixedly installed with the cover body 101. As Figures 1-2 shown, the reinforcing ribs 104 prevent the cover body 101 from deforming;

[0034] A plurality of internal threaded holes 107 are opened on the outer surface of the exhaust port 105. Each internal threaded hole 107 is arranged in a ring along the surface of the exhaust port 105. Positioning grooves 106 are symmetrically opened on the surface of the exhaust port 105, and the two positioning grooves 106 are respectively arranged outside the two internal threaded holes 107. An installation block 108 is fixed on the inner wall of the exhaust port 105. A plurality of ventilation holes 110 are opened on one side of the installation block 108.

When the overheated gas is discharged through the exhaust port 105, the air pressure pushes the check block 112 to move along the sliding groove 111, and the elastic member 113 is compressed and contracted. As a result, the ventilation hole 110 inside the mounting block 108 is communicated with the exhaust port 105. After the gas is completely discharged, the elastic member 113 resets, and the check block 112 blocks the ventilation hole 110 again to prevent the discharged gas from returning to the exhaust port 105 through the ventilation hole 110.

[0037] Connect the pipelines of the heat-conducting medium to the two connection ports 208, so as to circulate the heat-conducting medium into the liquid guide pipe 207. After the overheated gas passes through the heat-conducting plate 206, the heat is conducted to the heat-conducting medium inside the liquid guide pipe 207, and the heat-conducting medium flows out from the connection port 208 on the other side, thereby taking away the heat in the gas.
