Description

Technical Field

[0001] The utility model relates to the field of manufacturing of plate condensers, and particularly to a condensation channel plate for a plate condenser. Background Art

[0002] Existing plate condensers generally include heat exchange tubes and fins. The heat exchange tubes are dissipated by the fins, so that the refrigerant in the heat exchange tubes undergoes a phase change. Generally, an air-cooling method is used for heat dissipation. Since a structure of assembling the heat exchange tubes and the fins is adopted, it is necessary to open holes in the fins and insert the heat exchange tubes through the holes. The heat dissipation of this structure is uneven. The part in contact with the fins dissipates heat through the conduction of the fins, and the part not in contact with the fins dissipates heat through its own contact with the air. In such a case of uneven heat dissipation, the pressure of the refrigerant on the inner wall of the heat exchange tube is uneven, which easily leads to the rupture of the heat exchange tube and the damage of the fins; once damage occurs, it is simply impossible to disassemble and repair, and only the whole can be replaced, greatly increasing the use cost.
