Compared with other types of condensers, finned condensers usually have certain advantages in terms of cost; they are relatively simple to manufacture and install, with low cost, and can meet the heat dissipation needs of commercial display cabinets; the structure of finned condensers usually includes the following parts;

[0003] Base tubes: The core of the finned condenser is a set of neatly arranged metal tubes, usually copper or aluminum tubes; these tubes are responsible for transporting the refrigerant so that it can exchange heat in the condenser;

[0004] Fins: Fins are thin sheets of metal attached to the base tube. They increase the surface area for heat transfer. The shape and arrangement of the fins can affect air flow and heat transfer efficiency.

[0005] Connecting parts: The base tube in the finned condenser is connected to the refrigerant pipeline through connecting parts, such as elbows and tees, to form a complete cooling system;

[0006] Frame: The condenser usually has a frame to support and fix the fins and base tubes to ensure the stability of the entire structure;

[0007] Fan: To increase air flow and improve cooling, finned condensers may be equipped with a fan; the fan blows air across the fins, helping to remove heat;

[0008] The heat dissipation fins on the finned condenser are exposed. During transportation, the condenser may be subjected to collision, extrusion or other forms of external force impact, which may cause the fins to deform. Utility Model Content

At the same time, the gas inside the condenser tube 22 condenses into liquid and is discharged from the tube outlet 25, completing the condensation work;

[0032] As a preferred implementation, the heat dissipation fins 23 are made of metal copper and are of an "S"-shaped structure, and the distances between two adjacent groups of heat dissipation fins 23 are consistent.

[0033] like Figure 1-4 As shown: the plurality of groups of heat dissipation fins 23 are all of "S"-shaped structure, and the heat dissipation area of ​​the heat dissipation fins 23 in "S"-shaped structure is larger than that of rectangular fins;

[0034] By increasing the heat dissipation area, the efficiency of heat transfer is improved; the contact area between air and condenser can be increased, making it easier for heat to dissipate into the surrounding environment, thereby effectively reducing the temperature.

[0035] The space between the heat dissipation fins 23 is wider, which helps to guide the air flow, form a good air duct, improve the air convection effect, and improve the heat dissipation efficiency.

[0036] As a preferred embodiment, the front and back sides of the outer frame 21 are both equipped with protective grilles 212, and the protective grilles 212 are composed of a plurality of protective frames arranged in a regular six-shaped manner.

[0037] Protective grilles 212 are installed on the front and back of the outer frame 21. The two sets of protective grilles 212 can respectively protect the two sides of the heat dissipation fins 23. When the heat dissipation fins 23 are transported or moved, the heat dissipation fins 23 in the condenser are prevented from being impacted by collision, extrusion or other forms of external force, and the heat dissipation fins 23 are prevented from being deformed by force.

[0045] The arrangement of multiple groups of openings 231 can increase the heat dissipation area of ​​the heat dissipation fins 23: the openings 231 can create more surface area on the fins, thereby increasing the area for heat dissipation; this helps to improve the heat dissipation efficiency of the condenser;
