The liquid branch pipe 122 provides a low-temperature cooling medium. Several of the liquid inlet branch pipes 122 are located in the cooling chamber, and are used for the low-temperature cooling medium from the liquid inlet main pipe 121 to flow evenly into the cooling chamber, so that the temperature distribution of the cooling medium in the cooling chamber is relatively uniform, reducing the temperature difference of the cooling medium in different areas of the cooling chamber, thereby ensuring the uniformity of the surface temperature of the fixed anode furnace side door device 10 and improving the service life of the fixed anode furnace side door device 10; the liquid outlet pipe 13 is connected to the liquid outlet 112, and is used to discharge the high-temperature cooling medium after absorbing heat from the cooling chamber, thereby ensuring that the cooling chamber is always filled with relatively low-temperature cooling medium to protect the structure of the side door body 11.
