Description

Technical Field

[0001] The utility model relates to the field of plate-type condenser manufacturing, in particular to a condensation assembly for a plate-type condenser. Background Art

[0002] Existing plate-type condensers generally include heat exchange tubes and fins. The fins are used to dissipate heat from the heat exchange tubes, causing the refrigerant in the heat exchange tubes to change phase. Air cooling is generally used to dissipate heat. Since a structure in which the heat exchange tubes and fins are assembled is adopted, holes need to be opened in the fins, and the heat exchange tubes need to be inserted into the holes. The heat dissipation of this structure is uneven. The portion in contact with the fins dissipates heat through conduction of the fins, and the portion not in contact with the fins dissipates heat through contact with the air. This uneven heat dissipation will cause uneven pressure of the refrigerant on the inner wall of the heat exchange tube, which can easily lead to rupture of the heat exchange tube and damage to the fins. Once damage occurs, it is impossible to disassemble and repair it, and it can only be replaced as a whole, which greatly increases the cost of use. Summary of the invention

The refrigerant inlet and the refrigerant outlet are respectively provided at the upper and lower ends of the welding edge on the left side of the condensing sheet.
