The drain pipe 13 may discharge condensed water generated during heat exchange in the refrigerant pipe 12 to the outside, and the drain pipe 13 needs to be kept warm during the process to prevent the condensed water from being generated outside the drain pipe 13 and leaking out. The refrigerant pipeline 12 and the drain pipe 13 are arranged in the heat preservation layer 11, the refrigerant pipeline 12 can be heat-preserved and insulated to ensure the effect of cold and heat exchange of the refrigerant pipeline 12, and the drain pipe 13 is heat-preserved.
