Description
본 고안은 냉온수기 냉수통의 냉각코일에 관한 것으로 더 상세하게는 냉수통 외벽과 닿는 냉각코일 접촉부 단면을 변경하여 냉각코일을 따라 유동하는 냉매에 의한 냉각성능을 향상 시키고 냉각코일의 면 슬립(slip)을 줄이는 것이다.The present invention relates to a cooling coil of a cold water tank cold water tank, and more specifically, to change the cross section of the cooling coil contacting the outer wall of the cold water tank to improve the cooling performance by the refrigerant flowing along the cooling coil and to slip the surface of the cooling coil (slip) To reduce.
일반적으로 냉온수기의 냉수통(1)은 도 1과 같이 구멍이 있는 배플(2)을 설치하고, 배플(2) 중앙에 돌출된 구멍(3)을 통해 물을 유입시켜 히터 가열에 의해 온수로 만든다. 그리고 냉수통(1) 밑 부분의 외벽 둘레에 냉각코일(4)을 감아 놓아 배플(2)과 냉수통(1) 벽 사이의 틈새를 통해서 냉수통(1)으로 냉수를 공급하면서 냉수통(1)의 외벽 둘레에 감겨진 냉각코일(4)을 유동하는 저온 냉매에 의해 냉수통(1)을 따라 흐르는 물을 냉각 시켜 냉각수를 공급 하도록 되어 있다.In general, the cold water tank 1 of the cold and hot water heater is installed with a baffle 2 having a hole as shown in FIG. 1, and the water is introduced into the hot water by heating the heater through a hole 3 protruding from the center of the baffle 2. . The cold coil (1) is wound around the outer wall of the bottom of the cold bucket (1) to supply cold water to the cold bucket (1) through the gap between the baffle (2) and the cold bucket (1) wall. Cooling water flowing along the cold water tank (1) is cooled by the low temperature refrigerant flowing through the cooling coil (4) wound around the outer wall of the) to supply the cooling water.
냉수통(1)의 외벽에 감겨지는 냉각코일(4)은 냉각사이클에서 보면 증발기에 해당한다. 이 냉각코일(4)의 형태는 도 2와 같이 방사상의 면에 대하여 P점을 중심으로 점접촉 되는 원형 단면을 형성하고 있으며, 따라서 냉수통(1)의 외벽(5)과 접촉 되면 도 3과 점접촉 단면을 형성한다.The cooling coil 4 wound on the outer wall of the cold water container 1 corresponds to the evaporator in the cooling cycle. The cooling coil 4 has a circular cross section which is point-contacted with respect to the radial point with respect to the radial surface as shown in FIG. 2, so that when it contacts the outer wall 5 of the cold water container 1, FIG. A point contact cross section is formed.
냉각사이클에서 저온으로 압축된 냉매가 일정한 유동조건을 갖고 정해진 유동관을 따라 흐른다고 볼 때 냉매의 냉각성능은 냉매가 가지는 저온의 온도를 상대측에 전달하는 열교환 성능과 마찬가지다. 따라서 냉각코일(유동관)을 유동하는 저온의 냉매는 상대측과 열교환 될 때 가급적 냉매 접촉 단면적이 클 때 냉각성능이 향상 된다고 볼 수 있으며, 여기서의 냉각성능은 냉각사이클이 이루는 원래의 변수를 제외하고 유동 손실을 고려한 냉매의 열교환 효율만을 나타낸다.Considering that the refrigerant compressed to low temperature in the cooling cycle flows along a predetermined flow tube with a constant flow condition, the cooling performance of the refrigerant is the same as that of a heat exchanger that transfers the low temperature of the refrigerant to the other side. Therefore, the low-temperature refrigerant flowing through the cooling coil (flow tube) can be considered to have improved cooling performance when the refrigerant contact cross-sectional area is large when heat exchanged with the counterpart, where the cooling performance is different from the original variables of the cooling cycle. Only the heat exchange efficiency of the refrigerant in consideration of the loss is shown.
이런 측면에서 도 3과 같은 냉각코일(4)과 냉수통(1)의 접촉 형태는 열교환에 불리한 접촉 상태로 볼 수 있다. 즉 열교환 성능면에서 냉매에 의한 접촉 단면적은 클수록 좋아 지는데, P점 접촉 구조는 다른 어떤 접촉에 비해 열교환 성능이 떨어지기 때문이다. 이는 냉온수기에서 냉수통(1)을 유동하는 냉수의 온도를 저온화 시키는데 더 많은 냉매의 압축과 유동을 필요로 하는 원인이 된다. 냉매의 압축과 토출량을 늘려 보상할 수 있지만 더 많은 에너지가 필요하다. 예를들면 운전 모드를 '강'으로 하면 보통 충분한 저온의 냉각수 조성이 가능하지만 효율과는 무관하게 압축기의 운전에 드는 소비 에너지의 증가에 따른 것이고, 강/중/약은 냉각사이클에 의존하여 정해진 운전 모드일 뿐 역시 효율과는 무관하며, 운전에서 과냉은 에너지를 초과하여 사용한 것이다.In this aspect, the contact form of the cooling coil 4 and the cold water container 1 as shown in FIG. 3 may be regarded as a disadvantageous contact state for heat exchange. In other words, the larger the contact cross-sectional area by the refrigerant in terms of heat exchange performance, the better, because the P-point contact structure is inferior in heat exchange performance compared to any other contact. This causes a need for more compression and flow of the refrigerant to lower the temperature of the cold water flowing through the cold water tank 1 in the cold and hot water machine. This can be compensated by increasing the compression and discharge of the refrigerant, but more energy is required. For example, if the operation mode is set to 'strong', it is possible to form coolant at a low enough temperature, but regardless of the efficiency, the energy consumption of the compressor is increased, and the heavy / medium / weak is determined depending on the cooling cycle. The operation mode is also independent of efficiency, and in operation, subcooling is an excess of energy.
따라서 적은 에너지의 사용만으로 필요한 냉각성능을 유지할 수 있다면, '약'의 운전 모드로도 냉각수 온도를 저온화 시키는 것이 가능하다. 그러나 앞에서 냉각성능에 영향을 미치는 인자들 중 하나인 냉매의 열교환 단면적을 볼 때 종래의 구조는 열교환 성능이 떨어져 주위 온도 영향을 많이 받아 유동 손실이 커짐에 따라 빠른 시간에 냉수 저온화에 불리한 것이며, 냉각코일(4)과 냉수통(1)의 점 접촉은 냉각코일의 자중에 의한 슬립을 야기시켜 결속력에 약화되면 유동될 가능성이 크다.Therefore, if the required cooling performance can be maintained with only a small amount of energy, it is possible to lower the temperature of the coolant even in the 'about' operating mode. However, in view of the heat exchange cross-sectional area of the refrigerant, which is one of the factors affecting the cooling performance, the conventional structure is disadvantageous for cold water lowering in a short time as the flow loss increases due to the decrease in heat exchange performance and the influence of the ambient temperature. The point contact between the cooling coil 4 and the cold water container 1 is likely to flow when the cooling coil is slipped due to its own weight and weakened in the binding force.
따라서 본 고안의 목적은 냉수통에 감기는 냉각코일의 단면을 변경하여 유동 손실을 줄여 줌으로서 냉각코일을 흐르는 냉매와 냉수통을 유동하는 냉수의 열교환 성능을 향상 시키는 것이다.Therefore, an object of the present invention is to improve the heat exchange performance of the refrigerant flowing through the cooling coil and the cold water flowing through the cold water container by reducing the flow loss by changing the cross section of the cooling coil wound in the cold water container.
본 고안의 다른 목적은 냉수통과 냉각코일의 결합력을 강화 시키는 것이다.Another object of the present invention is to enhance the binding force between the cold water tank and the cooling coil.
이러한 목적을 달성하기 위한 본 고안의 특징은, 냉수통의 외벽 임의의 위치에 증발기에 해당하는 냉각코일을 여러번 감아 냉수통을 유동하는 냉수의 온도를 저온화 시키는 냉온수기 냉수통에 있어서,Features of the present invention for achieving this object, in the cold water heater cold water tank for reducing the temperature of the cold water flowing through the cold water container by winding the cooling coil corresponding to the evaporator several times on the outer wall of the cold water container,

The contact surface passing through is formed into a linear contact surface.
선택적으로, 냉각코일의 접촉면이 안으로 굴곡진 라운딩면으로 이루어지는 것을 특징으로 한다.Optionally, the contact surface of the cooling coil is comprised of a rounding surface curved inwardly.

You can.
이하, 본 고안의 실시예에 따른 냉수통의 구성예를 도면을 참고로 설명하면 다음과 같다.Hereinafter, a configuration example of a cold water container according to an embodiment of the present invention with reference to the drawings as follows.
도 4는 본 고안에 따른 냉수통의 외부 구조이고, 도 5는 도 4의 'B' 부 상세도 이며, 도 6은 냉수통 외벽과 닿는 냉각코일의 접촉 단면 형태 이며, 도 7은 냉각코일 접촉면의 다른 실시예를 나타낸다.Figure 4 is an external structure of the cold water container according to the present invention, Figure 5 is a detailed view 'B' of Figure 4, Figure 6 is a contact cross-sectional form of the cooling coil in contact with the outer wall of the cold water container, Figure 7 is a cooling coil contact surface Another embodiment of.
본 고안에 의한 냉수통의 구성은, 냉수통(10) 외벽(11)에 감겨져 냉수통(10) 외벽과 닿는 냉각코일(12)의 접촉면을 면접촉으로 유도하기 위해 냉각코일(12)에 선형 접촉면(13)을 형성하여 구성한다.The configuration of the cold water container according to the present invention is linear to the cooling coil 12 in order to guide the contact surface of the cooling coil 12 wound on the outer wall 11 of the cold water tank 10 to contact the outer wall of the cold water tank 10 with surface contact. The contact surface 13 is formed and comprised.
냉수통(10)의 외벽과 닿는 냉각코일(12)의 선형 접촉면(13)은 도 6과 같이 접촉 면적이 점 접촉에 비해 증가된 형태이며, 도 7과 같이 냉각코일(12)에 주어지는 선형 접촉면의 형태를 안으로 굴곡진 비선형 형태의 라운딩 접촉면(14)으로 형성하는 것도 가능하며, 마찬가지로 접촉 단면적이 점 접촉에 비해 증가된 형태이다.The linear contact surface 13 of the cooling coil 12 in contact with the outer wall of the cold water tank 10 has a form in which the contact area is increased as compared to point contact as shown in FIG. 6, and the linear contact surface given to the cooling coil 12 as shown in FIG. 7. It is also possible to form the shape of as a rounded contact surface 14 of a non-linear shape curved inwards, likewise having an increased contact cross-sectional area compared to point contact.
냉각코일(12)의 제작 방법은 먼저 파이프의 끝을 바이스에 물리고 바이스 반대편에서 프레스 금형으로 눌러 축관부(15)를 만들고, 이 축관부(15) 부터 냉수통(10)의 외경에 끼워질 수 있는 정도의 직경이 주어진 회전 하는 롤러 지그에 직선상의 파이프를 공급하여 연속적인 코일 형태로 감는다. 코일의 권수는 대략 6회 정도로 설정하여 절단 하여 냉각코일(12)로 만든다. 만들어진 냉각코일(12)의 각 끝은 한쪽이 축관부(15)를 이루면서 뚤려 있고 다른 한쪽은 절단된 구멍으로 뚫려 있는 상태이며, 이는 냉각코일(12)을 유동하는 냉매의 순환 유로를 형성한다. 냉각코일(12) 제작 과정에서 축관부(15)의 밴딩 작업을 병행 할 수 있다.The method of manufacturing the cooling coil 12 is to first pinch the end of the pipe to the vise and press the press die on the opposite side of the vise to form the shaft portion 15, which can be fitted from the shaft portion 15 to the outer diameter of the cold water tank 10. A straight pipe is supplied to a rotating roller jig of a given diameter and wound in a continuous coil form. The number of turns of the coil is set to about 6 times and cut to make the cooling coil 12. Each end of the made cooling coil 12 is a state in which one side is bent while forming the shaft tube portion 15 and the other end is opened by a cut hole, which forms a circulation flow path of the refrigerant flowing through the cooling coil 12. In the manufacturing process of the cooling coil 12, the bending work of the shaft pipe part 15 may be performed in parallel.
본 고안에 의한 바람직한 냉각코일(12)의 제작은 회전하는 롤러 지그에 동파이프를 감아 돌려 코일로 형성 하기 전 단계에서 냉수통(10) 외벽과 닿는 접촉면 부위 즉, 파이프의 안쪽 부분을 선형 접촉면(13)으로 형성 시킨 뒤 원하는 권수의 냉각코일(12)로 형성하는 것이다.The fabrication of the preferred cooling coil 12 according to the present invention is to wrap the copper pipe around the rotating roller jig to form a coil in contact with the outer surface of the cold water tank 10, that is, the inner part of the pipe in the linear contact surface ( 13) and then to form a cooling coil 12 of the desired number of turns.
파이프의 내벽에 선형 접촉면(13)을 제공하는 방법은 파이프 압출 과정에서 다이 형상 선택으로 간단히 만들 수 있으며, 기존 처럼 원형 단면의 파이프를 만든 뒤 내벽을 롤러와 같은 가공 다이로 눌러 소성 변형에 의해 원하는 선형 접촉면(13)을 얻을 수 있다. 그러나 코일로 제작한 상태에서 내벽을 선형 접촉면으로 변경 하기는 어렵다.The method of providing the linear contact surface 13 on the inner wall of the pipe can be simply made by selecting the die shape during the pipe extrusion process, and after making the pipe with the circular cross section as before, the inner wall is pressed by a processing die such as a roller to be desired by plastic deformation. A linear contact surface 13 can be obtained. However, it is difficult to change the inner wall into a linear contact surface in the coil manufacturing state.
도 7과 같은 비선형 단면 즉 파이프 내벽 가운데를 중심으로 안으로 들어간 형태의 라운딩 접촉면(14)도 선형 접촉면(13) 제작과 유사한 방법으로 만들 수 있다.A non-linear cross-section as shown in FIG. 7, that is, a round contact surface 14 having a shape centered in the center of the inner wall of the pipe may also be made in a manner similar to that of manufacturing the linear contact surface 13.
냉각코일(12) 제작이 완료되면 냉수통(10)을 따라 냉각코일(12)을 조립하고 냉각코일(12)의 유동을 방지하기 위해 몇 군데를 용접 하거나 결속하여 냉수통(10) 외벽에 냉각코일(12)을 장착한다.When the manufacturing of the cooling coil 12 is completed, assembling the cooling coil 12 along the cold water container 10 and welding or binding several places to prevent the flow of the cooling coil 12 to cool the outer wall of the cold water container 10. Mount the coil 12.
한편 파이프 단면이 원형 단면을 이루지 않고 선형 또는 비선형 단면으로 처리되어 롤러 지그에 의해 임의의 권수로 감겨져 만들어 지는 냉각코일(12)을 냉수통(10)을 따라 조립하여 냉수통 외벽(11)에 냉각코일(12)을 장착하면, 냉각코일(12)의 내벽과 냉수통(10) 외벽이 서로 닿는 부위가 점 접촉이 아닌 면접촉 단면으로 접촉된다.On the other hand, the cooling coils 12, which are formed by winding the rollers in arbitrary turns by being processed in a linear or non-linear cross section rather than having a circular cross section, are assembled along the cold water tank 10 and cooled on the cold water tank outer wall 11. When the coil 12 is mounted, a portion where the inner wall of the cooling coil 12 and the outer wall of the cold water tank 10 come into contact with each other is not a point contact but a surface contact end face.
이는 동일한 유동 공간을 따라 저온의 냉매가 유동하는 조건에서 냉수통(10)을 유동하는 냉수측과 냉매에 의한 열교환 면적을 증가시켜 상대적으로 유체의 급속한 저온화 현상을 유도한다. 그러나 저온의 냉매가 열교환을 거친 뒤 온도가 상승하여 이를 다시 저온 냉매로 되돌려 주기 위해서는 냉각사이클의 운전에 더 많은 에너지를 필요로 하지만 적은 시간에 저온 냉매에 의한 열교환이 가능하기 때문에 냉매의 유동 손실이 적다. 따라서 빠른 시간에 상온의 냉수를 저온화 시킬 것을 요구하는 냉온수기에 이러한 형태의 냉각코일을 적용하여 냉수통을 구성할 경우 냉매의 유동 손실 없이 냉수의 급속 저온화가 가능하다.This increases the heat exchange area by the cold water side and the refrigerant flowing through the cold water tank 10 under the condition that the low-temperature refrigerant flows along the same flow space to induce a rapid low temperature phenomenon of the fluid. However, in order for the low temperature refrigerant to undergo a heat exchange and rise in temperature and return it to the low temperature refrigerant, more energy is required to operate the cooling cycle. little. Therefore, if a cold water container is configured by applying this type of cooling coil to a cold / hot water machine requiring a low temperature of cold water at a rapid time, it is possible to rapidly lower the cold water without loss of refrigerant flow.
냉각코일(12)과 냉수통(10) 접촉면을 증가 시킨 본 고안과 같은 실시예에 의하면, 냉각코일(12)의 내경 사이즈를 냉수통(10) 외경 사이즈와 억지 끼워 맞춤 정도로 맞출 경우 접촉 면부에서 생기는 수직 'C' 방향 하중 내지 자중에 면 슬립을 상당히 줄일 수 있는 다른 결과를 얻을 수 있다. 따라서 냉수통(10)을 따라 장착된 냉각코일(12)의 유동이 적다.According to the embodiment of the present invention in which the contact surface of the cooling coil 12 and the cold water container 10 is increased, when the inner diameter size of the cooling coil 12 is matched to the outer diameter size of the cold water container 10 to a degree of interference fitting, Other results can be obtained which can significantly reduce the surface slip at the resulting vertical 'C' direction load or its own weight. Therefore, the flow of the cooling coil 12 mounted along the cold water container 10 is less.
이와 같이 본 고안은 냉온수기 냉수통의 구성에서 냉각코일과 냉수통의 접촉 단면적을 넓혀 냉매의 열교환 면적을 증가 시켜 줌으로서 상온 냉수의 급속 저온화를 필요로 하는 순간 냉온수기에 등에서 큰 효과를 얻을 수 있다. 또한 냉매의 유동 손실을 줄일 수 있으며, 냉수통과 냉각코일의 결합력을 강화 시켜 제품 신뢰도를 향상 시키는 효과가 있다.As described above, the present invention increases the heat exchange area of the refrigerant by expanding the contact cross-sectional area of the cooling coil and the cold water tank in the configuration of the cold and hot water cooler, and thus can obtain a great effect in the instant cold and hot water machine requiring rapid temperature reduction of the room temperature cold water. . In addition, the flow loss of the refrigerant can be reduced, and the product can be improved by strengthening the coupling force between the cold water tank and the cooling coil.
