Cooling pipe system

A cooling pipe system, comprising:

• an evaporation pipe slantly arranged, an input end of the evaporation pipe being higher than an output end of the evaporation pipe;
• a water inlet pipe, an output end of the water inlet pipe being connected to the input end of the evaporation pipe, the water inlet pipe being connected to a three-way valve for introducing gas into the evaporation pipe;
• and
• a water removal assembly located below the evaporation pipe and having a water sealing cavity, the output end of the evaporation pipe being connected to the water sealing cavity by means of a recovery pipe, the water sealing cavity being connected to a first pipeline extending upwards and communicated with the input end of the evaporation pipe, a lower end of the first pipeline being connected to a molecular sieve for preventing water vapor from passing through the molecular sieve, and the water removal assembly being configured for absorbing the water vapor.
