    Chiller of refrigerator
    The present invention relates to a cooling device of a refrigerator, and more particularly, by circulating a fluid to one end of a heat sink fin and at the same time expanding the heat insulating area of a pipe through which the fluid is circulated, thereby inducing effective heat dissipation of the heat sink fins, thereby allowing the refrigerator to cool down. The refrigerator relates to a refrigerator of which the structure is improved to increase the cooling efficiency of the refrigerator.
    In general, a refrigerator cooling apparatus of a compressed refrigerator applied to a refrigerator is divided into a freezer compartment and a refrigerator compartment by a trimmer plate, and a storage is accommodated in an internal space in which a plurality of pockets and shelves are formed, The machine room is formed.
    In addition, a compressor and a condenser pipe are installed in the machine room, and an evaporator and a blower fan are installed at the rear of the freezer to circulate the cold air generated from the refrigerant into the inside of the refrigerator to perform the freezing and cooling functions.
    In the conventional refrigerator configured as described above, the expansion and evaporation of the refrigerant in the refrigerant pipe is performed by forcibly circulating the high pressure refrigerant by the operation of the compressor to the condenser and the evaporator communicating with each other through the refrigerant pipe by the operating pressure of the compressor.
    In addition, the refrigerant circulating through the refrigerant pipe constituting the refrigerant cycle through the interaction of each component as described above is operated to freeze and cool the inside of the refrigerator.
    However, since the compressed refrigerator as described above has many necessary parts, the manufacturing process and assembly process are not only complicated, but also increase the manufacturing cost, and the volume of the refrigerator is excessive compared to the internal space in which food can be stored. There is a problem in that it is inconvenient to carry and install the refrigerator.
    As shown in FIG. 1, in the refrigerator of the refrigerator to compensate for the above problems, the thermoelectric device 10 employing a peltier effect in which the flow direction of the heat flow is determined in the same direction as the current flow direction is shown. Is coupled to the coupling groove 21 formed at the upper end of the cabinet 20, the heat dissipation fin 30 coupled to one end of the cabinet 20 so as to be in contact with one surface of the thermoelectric element 10, and the thermoelectric element 10. The aluminum block 40 is coupled to the other side of the heat conduction cooling heat is transferred from the thermoelectric element 10, and the cooling fin receives the cooling heat from the aluminum block 40 to supply the low-temperature air required for cooling in the refrigerator (50) It is composed of
    The thermoelectric element 10 employed in the electronic refrigerator is made of a junction of two different metals. When a current flows in the thermoelectric element 10, thermal energy is absorbed at one junction and radiated to another junction. Since the flow of heat flows from the cooling fins 50 contacted to both surfaces of the thermoelectric element, respectively, to the heat dissipation fins 30, the freezing and refrigerating effects of the refrigerator are obtained.
    That is, the thermoelectric device 10 as described above uses a peltier effect in which a heat flow flows from the inside to which the heat dissipation fins 30 are coupled to the inside of the aluminum block 40. By applying a current to the device 10, a flow direction of heat flow is formed from the cooling fins 50 to the heat dissipation fins 30, and heat is released from the inside to the outside to operate at low temperatures.
    However, the cooling device of the refrigerator as described above has a structure for cooling the heat dissipation fins 30 by air in the air, and thus does not effectively suck high heat generated from the outer surface of the thermoelectric element 10. Due to the limitations, the cooling efficiency of the refrigerator becomes a factor.
    On the other hand, in order to improve the heat dissipation of the heat dissipation fin 30 as described above, although a predetermined blowing fan is installed at an adjacent position of the heat dissipation fin 30, the air in the air is a heat dissipation fin because the temperature is constant. The amount of heat absorbed from 30 is also constant, so that a separate heat dissipation device is required.
    The present invention has been made to solve the above problems, and has the following object.
    First, a heat flow path for heat dissipation of the thermoelectric element is formed at an end of the heat dissipation fin, and a fluid tank and a fluid pump for supplying and circulating fluid through the flow path are provided at a predetermined position in the refrigerator, thereby forcing the heat dissipation fin through the forced circulation of the fluid. Heat dissipation secondary. In addition, by providing a plurality of coil capacitors extending from the fluid pipe and an auxiliary heat dissipation pipe formed to expand the heat dissipation area of the fluid pipe, the heat dissipated fluid is reduced to a temperature below a predetermined temperature by passing through the flow path of the heat dissipation fin. An object of the present invention is to provide a refrigerator of a refrigerator having an improved structure such that the heat flow of the device is smooth and the cooling efficiency of the cooling fin is increased.
    Second, by adopting the Peltier effect by the thermoelectric element, the electronic cooling method, which proceeds with cooling and heat dissipation, reduces the number of parts compared to the compressed refrigerator and shortens the manufacturing and assembly processes, thereby reducing the production cost of the refrigerator. The object is to provide an improved refrigerator cooling device.
    Third, by adopting the electronic cooling method, the number of parts required is reduced, and the repair and maintenance work is easy when the refrigerator breaks down, and the power consumption is reduced by the thermoelectric element cooling by supplying current from the power source, thereby reducing the economic cost. It is an object of the present invention to provide a refrigerator of the refrigerator having an improved structure.

    Hereinafter, a preferred embodiment of a cooling apparatus of a refrigerator according to the present invention will be described in detail with reference to the accompanying drawings.
    2 and 3 schematically illustrating a cooling apparatus of the present invention, the present invention provides a coupling groove 130 at an upper end of the thick plate cabinet 100 so as to pass through the outer box 110 and the inner box 120 of the refrigerator.

    And the fluid supply means for circulating a predetermined fluid through the fluid inlet (410, 420), and the heat dissipation means provided between the heat dissipation fin 400 and the fluid supply means to dissipate the fluid passing through one end of the heat dissipation fin 400 of the refrigerator Is provided in a predetermined position has a structure to improve the heat dissipation performance of the heat dissipation fin 400.
    In addition, the fluid supply means as described above includes a fluid tank 500 in which a predetermined amount of fluid is installed and provided with a predetermined space provided between the outer box 110 and the inner box 120 of the lower end of the refrigerator, and the fluid tank 500. And a fluid pipe 600 which is provided to communicate the fluid inlets 410 and 420 of the heat dissipation fin 400 and serves as a circulation path of the fluid, and at one end of the fluid pipe 600 between the fluid tank 500 and the heat dissipation fin 400.

    On the other hand, the heat dissipation means further has an effect of extending the length of the fluid pipe 600 by further installing an auxiliary heat dissipation pipe 610 formed by bending a plurality of at one end of the fluid pipe 600, Heats the air in the air to the heat dissipation fin 400 by installing a blowing fan 900 at one end of the outer case 110 so as to sufficiently dissipate heat from the circulating fluid and adjacent to the heat dissipation fin 400.
