plate fin 130 includes anupper plate fin 134 and alower plate fin 132. - The
lower plate fin 132 includes agroove 133 corresponding to an outer circumferential surface portion of therefrigerant pipe 110, so that therefrigerant pipe 110 is inserted into the groove along a path of therefrigerant pipe 110. - The
groove 133 may be implemented to correspond both of theheat radiating pipe 113 and thebent pipe 114, but in the present disclosure, thegroove 133 is provided to correspond to theheat radiating pipe 113. Therefore, thegroove 133 may be provided in at least two units thereof along the first direction 'W1' white corresponding to theheat radiating pipes 113. - As the main
refrigerant pipe 112 is inserted into thegroove 133, an upper portion thereof may be covered by theupper plate fin 134. One surface portion of theupper plate fin 134 may be provided to cover thelower plate fin 132 together with thegroove 133 into which the mainrefrigerant pipe 112 is inserted. - An
inner plate part 134a and anouter plate part 132a may be provided with structures identical to theupper plate fin 134 and thelower plate fin 132, respectively. - As described above, the

upper plate fin 134, thewave fin 140 may be provided. - The
wave fin 140 may have a plurality of first wave surfaces 142 and a plurality of second wave surfaces 144 that are correspondingly disposed in a bent manner to form a zigzag, and edge portions of the first wave surfaces 142 making contact with edge portion of the second wave surfaces 144 may form acrest part 148 and atrough part 146. - The first wave surface 14 and the
second wave surface 144 may be formed in the shape of, for example a plane surface, but as to increase the heat radiating surface, as in an embodiment of the present disclosure, the first wave surface 14 and thesecond wave surface 144 are preferred to be formed in a bent manner. - The

crest part 148 and thetrough part 146 may be provided to be disposed in a repeated manner in a plurality of times along the first direction 'W1', that is, the direction along which theheat radiating pipe 113 is wound. That is, thecrest part 148 and thetrough part 146 may be provided in a second direction 'W2' that is perpendicular to the first direction 'W1'. - The
crest part 148 and thetrough part 146 of thewave fin 140 are provided in the second direction 'W2' that is perpendicular to the first direction `W1' so that thewave fin 140 may be wound while maintaining thecrest part 148 and thetrough part 146 when therefrigerant pipe 110 provided in the first direction 'W1' is wound up in the direction perpendicular to theplate fin 130. - In addition, through the structure as such, the air that passes through the
wave fin 140 through theblower fan 56 may be guided through thecrest part 148 and thetrough part 146, and the structure as such may be able to enhance draft efficiency as the air is passed through in a direction perpendicular to the lengthways of theheat radiating pipe 113, and since the air being drafted may be concentrated in between thewave fin 140 and theplate fin 130, heat radiating efficiency may be enhanced. - The
condenser 100 may be formed of material having superior heat conductivity to enhance heat radiating efficiency. The refrigeratingpipe 110 and theplate fin 130 may be formed of aluminum material. - The above described components of the
condenser 100 may be assembled through a brazing method as to prevent leaking of refrigerant. That is, therefrigerant pipe 110, theplate fin 130, and thewave fin 140 each may be coated with clad material for a brazing method. - Thus, the
refrigerant pipe 110 is settled at thegroove 133 of thelower plate fin 132, theupper plate fin 134 is covered on thelower plate fin 132, and thewave fin 140 is disposed at one surface of theupper plate fin 134 to be inserted into a brazing furnace, so that thecondenser 100 may be assembled. - As the temporarily assembled
condenser 100 is heated at the temperature of about 600 and 700 in the brazing furnace, the clad material coated on the each component is melt as the melted clad material seals the joint portions the each component and firmly places the components together. Thus, the joint portions of the each component may be formed while having a certain gap as to seal the gap by use of the melted clad material. - The structure of the
condenser 100 in accordance with an embodiment of the present disclosure is not only applied to thecondenser 100, but may be applied to theevaporator 40 as a heat exchanger, as well as to an air conditioner and a refrigerator. - Through the above, within the limited space of the
machinery compartment 50, the heat radiating efficiency of the plurality of freezing cycles may be improved, and the energy that is consumed in heat radiation may be reduced. - Through the structure as such, the
condenser 100 that includes therefrigerant pipe 110 and the heat radiating part 120 may be provided with the shape of, for example a barrel as theplate fin 130 is wound up in a direction that surrounds thewave fin 140. - That is, the
plate fin 130 may be wound up in a perpendicular direction with respect to the first direction `W1' at which theheat radiating pipe 113 is disposed, and in detail, thelower plate fin 132 may be wound up in a way that thelower plate fin 132 is disposed at an outside that surrounds thecondenser 100. - The shape of a barrel may be formed in the shape of a body that is wound up in various shapes, such as the rectangular pillar shape as well as a cylindrical shape.
- Within the limited space of the
machinery compartment 50, the heat radiating efficiency of thecondenser 100 may be needed to be improved as to dispose theminiaturized condenser 100. - While using the pipe-
type refrigerant pipe 110 other than the tube-type refrigerant pipe 110 for thecondenser 100 in the wound-up shape of a barrel, the structure is provided in a way that thewave fin 140 is disposed at a space in between theplate fins 130. Through the structure as such, by using the pipe-type refrigerant pipe 110, the controlling of the flow of refrigerant is convenient, and in addition, the refrigerant may be made to be evenly distributed, while the improved heat radiating effect may be achieved as the heat radiation is taken place by thewave fin 140 even in the space in between theplate fins 130. - Hereinafter, the
condenser 100 having the structure as the above and the flow of refrigerant of a refrigerator having thecondenser 100 as such will be described. -
FIG. 8 is a drawing showing the flow of a refrigerant of thecondenser 100 in accordance with an embodiment of the present disclosure. - The flow of refrigerant by the structures of the
compressor 10, thecondenser 100, theexpansion valve 30, and theevaporator 40 is already described above and thus will be omitted, and the flow of the refrigerant at an inside thecondenser 100 will be described. - First, the refrigerant introduced through the
inlet part 116 is passed through therefrigerant pipe 113 disposed on the first virtual surface 'P1'. Then, after passing through thebent pipe 114 that connects therefrigerant pipe 113 on the first virtual surface `P1' to therefrigerant pipe 113 on the second virtual surface 'P2', the refrigerant flows through therefrigerant pipe 113 disposed on the second virtual surface 'P2', and after passing through thebent pipe 114 connected to therefrigerant pipe 113 on the second virtual surface 'P2', the refrigerant flows through therefrigerant pipe 113 on the third virtual surface 'P3'. Through the above the refrigerant that flows to therefrigerant pipe 113 on the fourth virtual surface 'P4' is released through theoutlet part 118 and is communicated to theexpansion valve 30. - During the process as the above, the
refrigerant pipe 113 primarily delivers heat to thelower plate fin 132 and theupper plate fin 134 that surrounds therefrigerant pipe 113, and secondarily, the heat is delivered to thewave fin 140 making contact with theupper plate fin 134. During the heat-delivering process as such, by the flow of the air that passes by the side surface of thecondenser 100, the heat may be discharged to an outside thecondenser 100. - By having the
wave fin 140 disposed in between theplate fins 130, the heat radiating surface is increased, and thus the heat radiating efficiency is enhanced, and even in a case of having the identical amount of heat radiation, the miniaturization of the condenser may be possible. - Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
