The present invention relates to a heat exchanger of a cooling and heating system, and in particular, after winding a spiral tube in which a refrigerant moves, to a spiral groove of a spiral jig, separating the spiral jig or two inner and outer spiral jigs having different diameters from each other. After wrapping the inner and outer spiral pipes together, the two inner and outer spiral jig are separated, and the inner and outer spiral pipes are pushed horizontally to overlap each other, so that the spiral heat exchanger made of a double is simple and convenient. The present invention relates to a jig for manufacturing a spiral heat exchanger and a manufacturing method using the same.

In general, a cooling device liquefies a refrigerant by compressing the refrigerant at a high pressure with an outdoor heat exchanger driven by a motor, and vaporizes the refrigerant in the indoor heat exchanger by evaporating the refrigerant condensed at this high pressure into a tube having a small diameter. Therefore, the temperature is lowered to generate cold air, and the cold air generated at this time is discharged to the room to perform cooling.

In addition, the refrigerant vaporized while absorbing heat in the indoor heat exchanger moves from the compressor to the outdoor heat exchanger to condense and liquefy to release heat to the outside to continuously cool through the above process.

On the other hand, in recent years, there has been a trend to use a combination of cooling and heating air conditioners that use both a cooling operation and a cooling operation, and this cooling and heating combined cooling device absorbs heat from the outside during the heating operation and releases it into the room. In the cooling operation, it has a dual operation structure that absorbs heat from the room and releases it to the outside.

Such cooling devices are used in air conditioners, refrigerators, and kimchi storages.

Looking at the configuration of the cooling, heating system of Figure 1, the compressor 14 for compressing the refrigerant moving through the pipeline to a high pressure; An outdoor heat exchanger (condenser) 15 for condensing the refrigerant compressed by the compressor 14 and discharging the heat to the outside; An expansion valve (4) for instantaneously expanding the refrigerant condensed in the outdoor heat exchanger (15); It consists of an indoor heat exchanger (evaporator) 2 to evaporate the external heat by evaporating the refrigerant expanded in the expansion valve 4 to lower the temperature.

As shown in FIG. 2, a configuration of a conventional outdoor heat exchanger 15 is connected to a refrigerant pipe in which heat is exchanged by being connected to an outlet 6 6 through which refrigerant is discharged from an inlet tube 5 through which refrigerant is introduced. (8) is stacked in a hexahedral shape consisting of a plurality of layers, between which the horizontal movement portion (7) is fixed by welding a thin wire to assist the discharge of the refrigerant transfer pipe (8) heat and to support the horizontal It is done by

The vertical connection part 9 is fixed to be installed to vertically connect the horizontal connection part 7.

On the other hand, as shown in Figure 8, look at the state of use of the outdoor heat exchanger 15, the refrigerant introduced through the inlet pipe (5) to move through the refrigerant moving pipe (8) stacked in a plurality of layers. do.

At this time, the blowing fan 16 installed on the bottom plate 13 by the support 18 rotates by the driving motor 19 to supply the cool air to the refrigerant moving tube 8, and moves along the inside thereof. The heat of the refrigerant is discharged to the outside to condense.

On the other hand, as shown in Figure 4, a view showing a state of an embodiment of applying the conventional outdoor heat exchanger 15 to the kimchi storage, the door 11 is rotated by a hinge on the top of the kimchi storage (10). It is mounted so that it can be opened and closed when putting or removing food such as kimchi in an inner container (not shown).

In addition, an operation panel for selecting and inputting ripening time and kimchi taste is attached to the upper part of the front side of the kimchi refrigerator 10, and a machine room in which various mechanical parts constituting the cooling device are installed below the kimchi refrigerator 10. 12) is provided.

At this time, on the bottom plate 13 in the machine room 12, a compressor 14 for compressing the refrigerant, and an outdoor heat exchanger 15 for cooling and condensing the refrigerant compressed at high temperature and high pressure are installed.

And, in front of the outdoor heat exchanger 15, a blowing fan 16 for pumping ambient air in accordance with the operation of the drive motor 19 is installed, to dissipate heat of the outdoor heat exchanger (15).

Accordingly, the refrigerant compressed by the compressor 14 is sent to the outdoor heat exchanger 15 through the refrigerant pipe 17, and the refrigerant condensed by the blower fan 16 is stored at the upper portion through the refrigerant pipe 17. It is supplied to an evaporator (not shown) wound in a container to keep food in the refrigerator fresh.

However, as described above, the conventional outdoor heat exchanger is laminated with a refrigerant moving tube for moving the refrigerant from the inlet pipe to the discharge pipe to have a constant interval and width, and the horizontal position between the refrigerant movement is fixed by supporting the position with a horizontal connection portion, Since the horizontal connector is fixed by using a vertical connector, the configuration is complicated, and thus manufacturing costs are increased, and manufacturing is deteriorated.

In addition, since the outdoor heat exchanger is formed in a stacked shape, the cooling efficiency is significantly reduced because the wind generated from the blower fan is not uniformly supplied as a whole, and thus the overall area of the outdoor heat exchanger is increased or blown to achieve cooling efficiency. It has disadvantages such as increasing the blowing capacity of the fan.
