    Chiller of refrigerator
    The present invention relates to a cooling device for a refrigerator. In particular, one end of the refrigerator includes a fluid tank and a fluid pump for forced circulation of the fluid from the fluid tank, thereby forcibly cooling the radiating fins by the fluid, thereby improving the cooling efficiency of the refrigerator. It relates to a refrigerator of the refrigerator so that the structure is improved.
    In general, a refrigerator is divided into a freezer compartment and a refrigerating compartment by a predetermined trimming plate, and food is accommodated in an inner space in which a plurality of pockets and shelves are formed. Is installed, the rear of the freezing chamber is provided with an evaporator and a blower fan to circulate the cold air generated from the refrigerant into the inside, thereby performing the freezing and cooling action.
    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 evaporator communicating with each other through the refrigerant pipe by the operating pressure of the compressor. Refrigerant circulating through the refrigerant pipe, which forms a refrigerant cycle by the operation, 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. Since the refrigerator is difficult to transport and install, there is a need for a refrigerator having a lighter and simpler structure while significantly reducing the number of parts.
    In order to meet the above demands, the electronic refrigerator having a simplified structure is commercialized around some small refrigerators, which is illustrated in FIG.
    The core component of the electronic refrigerator is a thermoelectric element to which the peltier effect is applied, and a schematic configuration thereof includes a heat dissipation fin 20 coupled to the rear plate portion 10 of the cabinet, and one side of the heat dissipation fin 20. The thermoelectric element 30 which is contact-coupled, the aluminum block 40 coupled to one side of the thermoelectric element 30 to conduct cooling heat from the thermoelectric element 30, and the cooling heat is transferred from the aluminum block 40. It is composed of a cooling fin 50 for supplying low-temperature air required for cooling in the refrigerator.
    The thermoelectric element 30 employed in the electronic refrigerator is made of a junction of two different metals. When a current flows in the thermoelectric element 30, thermal energy is absorbed at one junction point, that is, an aluminum block 40. ) Is coupled to the inside of the heat dissipation fins 20 is coupled to the outside using the Peltier effect (peltier effect), the heat radiation fins from the cooling fins 50 by applying a current to the thermoelectric element 30 The flow direction of the heat flow is formed at 20 so that heat is released from the inside to the outside to maintain the low temperature in the inside.
    However, the cooling device of the refrigerator has a structure that cools the heat dissipation fins 30 by natural air in the air, and does not quickly and effectively suck high heat generated from the outer surface of the thermoelectric element 10, thereby cooling the refrigerator. It is a factor which lowers.
    On the other hand, although a predetermined blower fan for inducing effective heat dissipation of the heat dissipation fin 30 as described above may be installed at an adjacent position of the heat dissipation fin 30, the air in the atmosphere is kept at a constant temperature. The amount of heat absorbed by the air intake from the heat radiation fins has a certain limit, so that a predetermined heat radiation device is required.
    The present invention has been made to solve the above problems, has the following object.
    First, it is easy to repair and repair when the refrigerator breaks down due to the reduced number of parts, and the refrigerator is improved in structure to reduce the economic cost by reducing the power consumption by the thermoelectric element cooling by supplying current from the power source. The purpose is to provide a cooling device.
    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, a 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 of the refrigerator to force the heat dissipation fin through the circulation of the fluid. It is an object of the present invention to provide a refrigerator of a refrigerator having an improved structure so that heat flow of a thermoelectric element and cooling efficiency of a cooling fin are increased by dissipating heat.
