A connection pipe group 250 and a cooler 260 are connected to the surface of the bottom plate 100. The connection pipe group 250 is communicated with the cold water chamber 240 and the cooler 260 respectively, and the cooler 260 is communicated with the water delivery member 210. In specific implementation, by starting the water delivery member 210, cold water enters the cold water chamber 240 of the fixing block 230 through the delivery pipe group 220. Since the fixing block 230 is attached to the surface of the furnace tube 120, the furnace tube 120 can be cooled down, reducing the possibility that the furnace tube 120 requires a long time for natural cooling and cannot be cooled quickly and effectively. The water in the cold water chamber 240 will be transported into the connection pipe group 250 and then into the cooler 260, which is beneficial to cooling the water with too high a temperature. The cooled water will be transported into the water delivery member 210, which is beneficial to recycling the water.

[0027] In this embodiment, the water delivery member 210 includes a water tank 211 and a water pump 212.

[0031] Specifically, the working principle of the cooling structure and the tubular heat treatment furnace: When in use, the furnace tube 120 is arranged between the lower furnace body 110 and the upper furnace body 300, which is beneficial to heat-treat the workpiece. By starting the water pump 212 on the surface of the bottom plate 100, the cold water in the water tank 211 is conveyed into the first connecting pipe 221 through the pipe body, and then conveyed into the cold water cavity 240 of the fixing block 230 through the first three-way pipe 222 and the conveying pipe 270.
