It can be understood that the integrated double pipe for heat exchange according to an embodiment of the present invention includes a supply pipe 100 and a control pipe 200.

The supply pipe 100 is formed with a flow path in one direction and may serve as a passage through which water flows from a water supply source such as a water supply pipe or a bottle of water.

The control pipe 200 is in contact with the supply pipe 100 along the longitudinal direction of the supply pipe 100, and serves to change the water temperature in the supply pipe 100 by the energy supplied from the outside.

Here, the supply pipe 100 and the control pipe 200 is formed integrally and the heat transfer between each other is made directly.

In this case, the control pipe 200 may heat or cool the water in the supply pipe 100 by the energy supplied from the temperature control unit C connected to the control pipe 200 as shown in FIG. 1.

The present invention is applicable by the embodiment as described above, will be described in more detail for the main part of the present invention for a more detailed description.

As described above, the supply pipe 100 has a flow path in one direction, and as shown in FIG. 1, one side is connected to the water supply pipe 500 ′ and the other side is connected to the drain valve 500.

As described above, the control pipe 200 is formed integrally with the supply pipe 100 to cool or heat the water in the supply pipe 100, and the supply pipe 100 and the control pipe 200 are made of aluminum or an aluminum alloy. The inner and outer circumferential surfaces of the supply pipe 100 and the control pipe 200 are preferably anodized, anticorrosive coating, or anticorrosive resin coating.

When the anticorrosive coating or the anticorrosive resin is applied to the object to be coated, a material such as epoxy or Teflon having excellent heat resistance and impact resistance may be coated on the inner and outer circumferential surfaces of the supply pipe 100 and the control tube 200.

The anodizing treatment protects the inside of the aforementioned metals by making a thin oxide film on the surface of the above-described metals, which are highly reactive with oxygen such as aluminum, titanium, magnesium, and the like, to form an oxide film on their own surface.

The anodizing treatment described above artificially produces an oxide film having a uniform thickness by promoting the oxidation of the surface of the aforementioned metals while allowing the aforementioned metals to function as an anode in a specific solution such as sulfuric acid.

Like the metals described above, metals having a high degree of reaction with oxygen form an oxide film by themselves to protect themselves, but due to its high reactivity, impurities such as iron, silicon, or copper are inevitably included.

When the content of the above-mentioned impurities is high, the metals such as Al ₃ Fe, Al ₆ Fe, Al ₅ FeSi, Al ₂ Cu, etc., are formed between the above-mentioned impurities and the above-described metals (hereinafter, aluminum) during the manufacture of the product using the above-described metals. Compounds (Intermetallics, hereinafter referred to as IMC) are generated, and the aforementioned IMC, unlike aluminum, cannot generate an oxide film by itself.

Here, if the aluminum or aluminum alloy having a high impurity content is left in the air and used as it is, a fatal problem may occur such that the above-mentioned IMC is formed with holes or corroded and stress is concentrated.

Therefore, the above-described anodizing applies the principle that the above-mentioned IMC can also form an oxide film when an IMC that cannot form an oxide film in air is added to a specific solution such as sulfuric acid.

Meanwhile, as described above, the supply pipe 100 and the control pipe 200 are formed to be integrally formed by casting or extruding aluminum or an aluminum alloy, and by turning at least one or more times as shown in FIGS. 2 and 3 to form a coil shape as a whole. The control pipe 200 is disposed inside the coil shape, and the supply pipe 100 is disposed outside the coil shape.

The control tube 200 is arranged to be inside the coil shape in order to allow cooling or heating of the water in the supply pipe 100 continuously without cooling air or warm air to the outside.

Here, the supply pipe 100 and the control pipe 200 is not limited to the coil shape as shown, and various modifications of the design, such as linear or plural curved meandering shapes, depending on the environment and the size of the space to be installed. It is possible.

At this time, the supply pipe 100 and the control pipe 200 may be used by anodizing, anticorrosive coating or anticorrosive resin coating on the inner and outer circumferential surfaces as described above, as well as to improve the thermal conductivity to the supply pipe 100 side or In order to improve corrosion resistance or to maintain good hygiene, a separate pipe material may be additionally inserted into the supply pipe 100 and the control pipe 200 respectively or selected.

That is, the control tube 200 is inserted into the inner tube 210 made of copper or copper alloy excellent in thermal conductivity, as shown in the enlarged portion A of Figure 1, the outer peripheral surface of the inner tube 210 is the inner peripheral surface of the control tube 200 It is possible to apply a structure for fixing in contact with.

And, the control tube 200 is inserted into the first inner tube 220 made of copper or copper alloy as shown in the enlarged portion B of Figure 1 and the outer peripheral surface of the first inner tube 220 and the inner peripheral surface of the control tube 200 It is fixed in contact with the supply pipe 100 is inserted into the second inner tube 120 made of stainless steel, synthetic resin, or ceramic and the outer peripheral surface of the second inner tube 120 is fixed in contact with the inner peripheral surface of the supply tube 100 You can also apply

In this case, when the water in the supply pipe 100 is to be cooled in the control tube 200, the inner tube 210 may be inserted as shown in the enlarged portion A of FIG. 1 to allow the refrigerant to flow. When the heating is to be carried out by the heat transfer device, the configuration of the inner tube 210 may be omitted, or if the steam flows, the inner tube 210 may be selectively installed and modified.

At this time, the control tube 200, if you want to heat the water in the supply pipe 100, as shown in Figure 2 built-in the heater rod 301 connected to the external power source 700, or not shown in particular, but connected to the steam generating device high temperature Of course, it is possible to apply such that the steam of the flow.

In addition, the control tube 200 may cool the water in the supply pipe 100 by flowing a refrigerant as shown in FIG. 3.

That is, one side of the control tube 200 is the capillary tube 310, the other side of the control tube 200 is connected to the compressor 330, respectively, between the capillary tube 310 and the compressor 330 The condenser 320 is mounted, and the refrigerant forms a cooling cycle circulating in one direction from one side of the control tube 200 to the other side to continuously cool the water in the supply pipe 100.

At this time, it is preferable that the dryer 340 is mounted between the condenser 320 and the capillary tube 310.

That is, the compressor 330 converts the refrigerant into a saturated steam of high temperature and high pressure by thermally compressing the refrigerant, and the condenser 320 converts the refrigerant discharged from the compressor 330 into a saturated liquid of low temperature and high pressure, and the dryer 340. Removes foreign substances contained in the refrigerant in a saturated liquid state at low temperature and high pressure.

Subsequently, the refrigerant from which foreign substances have been removed is throttled in the capillary tube 310 to become a low-temperature low-pressure wet vapor, and vaporized in a control tube 200 which is an evaporator to absorb latent heat of external air to cool the surrounding air. Let's do it.

 Thereafter, although the refrigerant discharged from the control tube 200 is not particularly illustrated, the accumulator is separated into a liquid refrigerant and a gaseous refrigerant, and only one gaseous refrigerant is returned to the compressor 330, thereby completing one rotation of the cooling cycle. The cycle is repeated.
