AI Technical Summary
Technical Problem
The existing refrigerant flow channels in the evaporator of the snow melting machine have cooling dead zones, resulting in poor heat exchange efficiency.
Method used
The evaporator cylinder adopts a tubular structure, with outward-protruding spiral protrusions and spiral concave parts on the outer side of the inner cylinder, forming continuous or spliced spiral protrusions. The inner and outer cylinders cooperate to form a spiral flow channel, ensuring that the refrigerant is completely filled and eliminating cooling dead zones.
Benefits of technology
This improved the heat exchange efficiency of the evaporator cylinder, enhanced heat conduction, reduced energy consumption, and extended the service life of the equipment.

Abstract
The utility model discloses a tubular structure, an evaporation cylinder and a snow melting machine, the outer side surface of the tubular structure is provided with a spiral convex part protruding outwards, the part of the outer side surface except the spiral convex part forms a spiral concave part, and the head part and the tail part of the spiral concave part are respectively provided with a through hole; the head end and the tail end of the spiral convex part are close to the two ends of the outer side face respectively, and the axial distance between the head end and the tail end of the spiral convex part is smaller than that between the head end and the tail end of the spiral concave part. When the tubular structure is configured to be the inner barrel of the evaporation cylinder, a refrigerant flow channel formed by the outer wall of the tubular structure can be completely filled with a refrigerant, and the head end and the tail end of the spiral convex part are completely immersed in the refrigerant. When the tubular structure is used as an inner barrel of the evaporation cylinder, a refrigerant can be fully covered in a flow channel on the outer side face of the tubular structure, and cooling dead angles are eliminated.
