Abstract

The application discloses a super-hydrophilic and super-hydrophobic heat exchange surface combined evaporation heat exchange tube and a manufacturing method thereof. The heat exchange tube comprises a tube body, wherein an outer surface of the tube body is provided with outer fins extending spirally in a length direction of the tube body and an outer ditch formed between the outer fins and extending spirally in the length direction of the tube body; the outer ditch is provided with a copper stranded wire winding the tube body, and the copper stranded wire is formed by twisting at least two copper wires, at least one of the copper wires has a super-hydrophilic surface and the other one has a super-hydrophobic surface. The heat exchange tube has the super-hydrophilic and super-hydrophobic surfaces at the same time, the heat exchange surface formed by the different hydrophilic and hydrophobic surfaces integrates advantages respectively, a higher heat exchange coefficient is kept in the whole period of a boiling phenomenon and the boiling heat exchange coefficient is improved.

Description

technical field [0001] The present application relates to an evaporative heat exchange tube, in particular to an evaporative heat exchange tube with combined superphilic and hydrophobic heat exchange surfaces and a manufacturing method thereof. Background technique [0002] The enhanced evaporation heat exchange tube is an important part of the flooded evaporator. At present, commercial enhanced evaporation heat exchange tubes are often called "T" shaped tubes. It is characterized in that the surface of the heat exchange tube has dimples, and the dimples communicate with the refrigerant on the shell side through the narrow slit at the top. After a large number of bubbles are generated, they leave the heat exchange tube through the slit to form sufficient boiling. The total heat transfer coefficient of this evaporative heat exchange tube is more than 3 times higher than that of the light tube, which has obvious performance advantages. However, the processing of this type of...
