Heat dissipating fin for use in heat exchanger

Abstract

The invention relates to a heat dissipating fin of a heat exchanger, more particularly, which is designed to facilitate coupling the heat dissipating fin with a refrigerant pipe in an assembling process of a heat exchanger as well as to improve heat dissipating efficiency. According to an aspect of the invention for realizing the above objects, there is provided a heat dissipating fin 20 for used with a heat exchanger, which includes a refrigerant pipe 10 and the heat dissipating fin 20 coupled with the refrigerant pipe 10 . The heat dissipating fin 20 has slits 21 formed therein in series for allowing U-shaped bends 11 of the refrigerant pipe 10 to simultaneously pass through the slits 21 , whereby the bends 11 of the refrigerant pipe 20 formed by successively bending the refrigerant pipe 10 into a serpentine configuration are inserted into the slits 21 at the same time so as to couple the heat dissipating fin 20 with the refrigerant pipe 10.

1 . A heat dissipating fin for use in a heat exchanger, which includes a refrigerant pipe and the heat dissipating fin coupled with the refrigerant pipe, wherein the heat dissipating fin has slits formed therein in series for allowing U-shaped bends of the refrigerant pipe to simultaneously pass therethrough, whereby the bends of the refrigerant pipe formed by successively bending the refrigerant pipe into a serpentine configuration are inserted into the slits at the same time so as to couple the heat dissipating fin with the refrigerant pipe.  
   
   
       2 . The heat dissipating fin according to  claim 1 , wherein the slits are formed horizontally in parallel or oriented at a predetermined inclined angle in parallel.  
   
   
       3 . The heat dissipating fin according to  claim 1 , wherein each of the slits has coupling holes formed at both ends thereof with the same size as the diameter of the refrigerant pipe, and an opening formed between the coupling holes with a width smaller than the diameter of the refrigerant pipe, and wherein each of the U-shaped bends of the refrigerant pipe has a flat inserting portion formed by pressing the bend, with a thickness the same as the width of the opening, whereby when the inserting portions of the U-shaped bends are inserted into the openings, semicircular portions of the refrigerant pipe are stably inserted without movement through the coupling holes at both ends of the slits.  
   
   
       4 . The heat dissipating fin according to  claim 1 , wherein the heat dissipating fin has a reinforcing portion formed by pressing a predetermined area of the heat dissipating fin between the slits, to thereby increase the overall durability of the heat dissipating fin.  
   
   
       5 . The heat dissipating fin according to  claim 1 , wherein the heat dissipating fin has inwardly bent support pieces formed at predetermined regions of the heat dissipating fin, the support pieces being semicircularly shaped at both ends of the slits for receiving the refrigerant pipe, or at peripheral portions of the coupling holes, which are formed at both ends of the slits to be coupled with the refrigerant pipe.
