  • the refrigeration cycle includes a compressor, a condenser, an evaporator and a capillary tube.
  • the compressor serves to compress a refrigerant into a high-temperature and high-pressure gas-phase refrigerant
  • the condenser serves to condense the refrigerant transmitted from the compressor into a high-temperature and high-pressure liquid-phase refrigerant.

  • the present invention provides a method of manufacturing a heat exchanger for a refrigerator, the heat exchanger including a refrigerant guiding tube for receiving refrigerant and a turbulent flow inducing member, comprising the steps of: inserting the turbulent flow inducing member into a refrigerant guiding tube; and bending the refrigerant guiding tube.
  • the method may further comprise the step of inserting the turbulent flow inducing member longitudinally in the direction of the refrigerant guiding tube.
  • the method wherein the turbulent flow inducing member may be a wire bent in a serpentine manner.
  • the method wherein the turbulent flow inducing member may have a coil spring shape.
  • the method wherein the turbulent flow inducing member may have a twisted plate shape.

  • the refrigeration cycle is a closed circuit and comprises a compressor 3, a condenser 4, a capillary tube 5, a drier 7, an evaporator 6, and interconnecting refrigerant tubes 8.
  • the capillary tube 5 may be replaced with another expansion device such as an expansion valve.
  • the compressor 3 serves to compress a refrigerant into a high-temperature and high-pressure gas-phase refrigerant.
  • the condenser 4 serves to condense the refrigerant from the compressor 3 into a high-temperature and high-pressure liquid-phase refrigerant.
  • the drier 7 may be installed on an intermediate position of the refrigerant tube 8 that connects the condenser 4 and capillary tube 5 to each other.
  • the drier 7 serves to remove moisture contained in the gas-phase refrigerant condensed in the condenser 4.
  • the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser 4 is subjected to a throttling expansion while passing through the capillary tube 5 and is thereby changed into a low-temperature and low-pressure liquid-phase refrigerant.
  • the evaporator 6 serves to evaporate the low-temperature and low-pressure liquid-phase refrigerant into a low-temperature and low-pressure gas-phase refrigerant.
  • the evaporator 6 and condenser 4 serve as heat exchangers.
  • the evaporator 6 and condenser 4 consistent with the present invention causes the refrigerant flowing therein to form turbulent flow thereby improving the heat transfer efficiency.
  • the refrigerator comprises a body 10 provided with constituent elements of a refrigeration cycle.
  • the body 10 is internally defined with a storage chamber 11 having an opening formed at a front surface thereof.
  • a door 20 may be coupled to the front surface of the body 10 by use of hinges in a pivotally rotatable manner, providing access to the storage chamber 11.
  • Both the compressor 3 and condenser 4 may be installed in a machine room 12 that may be defined in a lower portion of the body 10 separate from the storage chamber 11.

  • the refrigerant circulating in the refrigeration cycle emits heat when condensed in the condenser 4 via heat exchange with the air in the machine room 12, and absorbs heat from the air inside the storage chamber 11 when evaporated in the evaporator 6 via heat exchange with the air inside the storage chamber 11.
  • the air inside the storage chamber 11 is cooled into cold air via heat exchange with the evaporator 6. Accordingly, the evaporator 6 and condenser 4 serve as heat exchangers for the refrigerator.
  • FIG. 3 illustrates the heat exchanger 4 or 6 for the refrigerator consistent with the present embodiment.
  • Each heat exchanger 4 or 6 includes a refrigerant guiding tube 30 similar to a conventional refrigerant tube and a plurality of heat exchange fins 40 coupled around an outer peripheral surface of the refrigerant guiding tube 30 to increase a heat exchange area.
  • Each heat exchanger 4 or 6 may also include a supporting member 50 and another supporting member 51.
  • the refrigerant guiding tube 30 is preferably made of a flexible material, such as copper, and may have a circular cross section.
  • the refrigerant guiding tube 30 is initially manufactured to have a straight pipe shape.
  • the refrigerant guiding tube 30 After coupling the plurality of heat exchange fins 40 around the outer peripheral surface of the refrigerant guiding tube 30, the refrigerant guiding tube 30 is repeatedly bent in a generally serpentine manner, to have a multistage multiple-row structure. Then, a pair of supporting members 51 and 52 may be coupled to the ends of the multistage multiple-row structure to maintain the shape of the heat exchanger 4 or 6.
  • the refrigerant guiding tube 30 is provided therein with a turbulent flow inducing member 60 to cause the refrigerant flowing along the tube 30 to form a turbulent flow.
  • the turbulent flow inducing member 60 is arranged along a longitudinal direction of the refrigerant guiding tube 30, and extends throughout the refrigerant guiding tube 30 to cause the refrigerant to form a turbulent flow throughout the refrigerant guiding tube 30.
  • the turbulent flow inducing member 60 may be configured as a wire, bent in a serpentine manner to have a plurality of bent portions 61 substantially orthogonal to the longitudinal direction of the refrigerant guiding tube 30.
  • the turbulent flow inducing member 60 When the turbulent flow inducing member 60 is disposed in the refrigerant guiding tube 30, the refrigerant flowing along the refrigerant guiding tube 30 collides with each bent portion 61 of the turbulent flow inducing member 60, thereby forming a turbulent flow rather than a laminar flow. Because the refrigerant passing through the refrigerant guiding tube 30 has an irregular turbulent flow, the refrigerant flowing closest to an inner surface of the refrigerant guiding tube 30 and refrigerant flowing in the center of the tube 30 actively exchanges heat across the walls of the refrigerant guiding tube 30. Thus, substantially all the refrigerant actively exchanges heat with air surrounding the refrigerant guiding tube 30, resulting in improved heat transfer efficiency for heat exchanger 4 or 6.
  • the turbulent flow inducing member 60 is preferably made of an elastically deformable material and is adapted to have a width slightly smaller than a diameter of the refrigerant guiding tube 30, to allow insertion into the refrigerant guiding tube 30.
  • Each heat exchange fin 40 is centrally perforated with a tube penetration hole 42 adapted to be coupled around the outer peripheral surface of the refrigerant guiding tube 30.
  • FIGS. 6 to 8 illustrate turbulent flow inducing members 60', 60", 60"' consistent with alternative embodiments of the present invention.
  • the turbulent flow inducing member 60' may have a coil spring shape.
  • the turbulent flow inducing member 60" may have a twisted plate shape.
  • the turbulent flow inducing member 60"' may include a rod shaped body 61"' extending in the longitudinal direction of the refrigerant guiding tube 30 and a plurality of protrusions 62"' formed at an outer peripheral surface of the body 61"' to protrude substantially orthogonal to a flow direction of the refrigerant flowing along the refrigerant guiding tube 30.
  • the turbulent flow inducing members 60, 60', 60" and 60'" may have other various shapes so long as they can create a resistance against the refrigerant flowing in the refrigerant guiding tube 30, thereby causing the refrigerant in the refrigerant guiding tube 30 to form a turbulent flow.
  • the heat exchange fins 40 may first be coupled around the outer peripheral surface of the refrigerant guiding tube 30.
  • the turbulent flow inducing member 60 is completely inserted into the refrigerant guiding tube 30 in a manner as shown in FIG. 10.
  • the refrigerant guiding tube 30 is bent in a serpentine manner to have a multistage multiple-row structure as shown in FIG. 11.
  • the supporting members 51 and 52 may be coupled to the sides of the multistage multiple-row structure formed from bending the refrigerant guiding tube 30.
  • the turbulent flow inducing member 60 was inserted into the refrigerant guiding tube 30 prior to bending the refrigerant guiding tube 30, the turbulent flow inducing member 60 is bent together with the refrigerant guiding tube 30 in the course of bending the refrigerant guiding tube 30. Therefore, in one embodiment, when the refrigerant guiding tube 30 is bent in a serpentine manner, the turbulent flow inducing member 60 is caught by bent portions of the refrigerant guiding tube 30 and supported thereby. Thus, the turbulent flow inducing member 60 can be secured in the refrigerant guiding tube 30 in a fixed position.
  • each of the turbulent flow inducing members 60', 60" or 60"' may be fixedly secured by bending the refrigerant guiding tube 30 while assembling the heat exchanger 4 or 6, similar to the turbulent flow inducing member 60 of the previously described embodiment.
  • the heat exchanger 4 or 6 for the refrigerator having the turbulent flow inducing member 60 consistent with the present invention can eliminate the need for a separate securing means for securing the turbulent flow inducing member 60 at a fixed position and improve heat transfer efficiency. Therefore, eliminating separate securing means and improving heat transfer efficiency can reduce the cost associated with adding the turbulent flow inducing member 60.
  • the present invention provides a heat exchanger for a refrigerator in which a refrigerant guiding tube has a turbulent flow member disposed therein.
  • a refrigerant guiding tube has a turbulent flow member disposed therein.
  • the refrigerant flowing along a refrigerant guiding tube forms an irregular turbulent flow.
  • the entire refrigerant being guided along the refrigerant guiding tube can be moved toward an inner surface of the refrigerant guiding tube, and thus, actively exchange heat with the air surrounding the refrigerant guiding tube, resulting in a considerably improved heat transfer efficiency.
