[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-2 An energy-saving air-cooled condenser includes a flat tube 1. Both sides of the flat tube 1 are provided with collecting pipes 2, which are connected to the flat tube 1. The two collecting pipes 2 are provided with connecting pipes 3 connected thereto. The two connecting pipes 3 are respectively used for the flow in and out of the refrigerant. The surface of the flat tube 1 is provided with a plurality of heat dissipation fins 4.
[0018] Side plates 5 are provided on both upper and lower sides of the flat tube 1, and the side plates 5 are used to connect with the frame of the chiller. Mounting holes 6 are provided on the side plates 5, and the entire air-cooled condenser is mounted and fixed on the frame by bolts.
[0019] Working principle: The refrigerant gas enters the manifold 2 through the connecting pipe 3. The manifold 2 distributes the refrigerant gas to each flat tube 1 for condensation and cooling. The air takes away the heat of the refrigerant in the flat tube 1 through the heat dissipation fins 4 between the flat tubes 1. The side plate 5 is used to fix the air-cooled condenser to the frame structure of the chiller, which is convenient for saving refrigerant. Under the premise of the same equipment performance, about half of the refrigerant can be saved.
[0020] In addition, a heat dissipation channel is left between two adjacent heat dissipation fins 4. The heat dissipation fins 4 are provided with a corrugated structure 7, which can play a role in turbulence, better reduce the temperature difference of each wind layer, thereby greatly improving the heat value contained in the unit air volume; under the same heat exchange area, the heat exchange efficiency of the corrugated fin is significantly improved than that of the ordinary flat plate type.
