본 고안은 수냉식공기조화기의 열교환장치에 관한것으로, 특히 수중펌프로 끌어올린 물을 회전하는 접시형 확산판에 분사함으로써 열교환성능을 향상시킨 응축기 열교환장치에 관한 것이다.The present invention relates to a heat exchanger of a water-cooled air conditioner, and more particularly, to a condenser heat exchanger that improves heat exchange performance by spraying water drawn by an underwater pump onto a rotating plate-type diffusion plate.
일반적으로 수냉식공기조화기에 있어서는 열매체로서 물을 이용하여 응축기를 냉각하게 되는데 제1도는 참조하여 종래의 기술을 살펴보면, 냉각수(1)를 보유하고 있는 함체(10)가 구비되어 있고, 그 중앙하부에 수중펌프(20)가 제공되어 수중펌프에 연결된 상승관(30)을 통해 물을 올려주게되고, 상기 함체(10)에 냉각수안내판(40)이 구비되어 수중펌프(20)로부터 올려진 물을 응축기(50)로 유도하게 되며, 응축기브라켓트(60)의 외주연에 일정간격을 두고 배열되어 있는 응축기(50)는 안내판(40)에 유도되어 낙하하는 물에 의해 냉각되며 열교환을 이루게 된다.In general, the water-cooled air conditioner cools the condenser by using water as a heat medium. Referring to FIG. 1, the conventional technology is described with reference to FIG. 1, wherein a housing 10 having a cooling water 1 is provided. Submersible pump 20 is provided to raise the water through the riser pipe 30 connected to the submersible pump, the cooling water guide plate 40 is provided in the housing 10 condenser condenser water raised from the submersible pump 20 Induced by 50, the condenser 50 arranged at a predetermined interval on the outer periphery of the condenser bracket 60 is guided to the guide plate 40 is cooled by the falling water to form a heat exchange.
또한 안내판(40)의 상부에는 열교환되는 냉각수의 열을 덕트(90)를 통하여 외부로 방출하는 송풍팬(70)과 송풍팬모터(80)가 구비되어 있다.In addition, the upper part of the guide plate 40 is provided with a blowing fan 70 and a blowing fan motor 80 for discharging the heat of the cooling water to the outside through the duct 90.
그러나 이와같은 수냉식열교환장치에 있어서는 수중펌프(20)로 올려 보내진 냉각수(1)를 응축기(50)로 안내하는 안내판(40)이 함체 (10)에 고정되어 있고 또한 그 안내면이 평평하게 구성되어 있으므로 인해 냉각수가 미쳐 응축기(50)에 도달하기 전에 자중에 의해 낙하하는 량이 많아지게 되어 응축기 열교환성능이 저하되는 요인이 되었다.However, in such a water-cooled heat exchanger, the guide plate 40 for guiding the cooling water 1 sent to the submersible pump 20 to the condenser 50 is fixed to the enclosure 10 and the guide surface is flat. As a result, the amount of the coolant falls down by its own weight before reaching the condenser 50, resulting in a decrease in the condenser heat exchange performance.
즉 수중펌프(20)가 냉각수를 올려보내는 힘은 일정한데 비해 안내판(40)의 형상이 평평하고 또한 고정되어 있으므로 냉각수는 수중펌프로 부터 부여받은 힘만으로 응축기로 이동을 하여야 하는데, 이때 냉각수는 안내판에 분사될때 충격으로 그 힘이 감소되고, 또한 안내판면을 따라 이동도중에도 마찰력 및 중력에 의해 그 진행력이 약화되어 응축기에 미쳐 도달하기 전에 낙하하게 되는 것이다.That is, the power of the submersible pump 20 to raise the coolant is constant, but the shape of the guide plate 40 is flat and fixed, so the coolant must move to the condenser with only the force given by the submersible pump. When it is injected into the impact, the force is reduced, and even during the movement along the guide plate, the force is weakened by friction and gravity, and fall before reaching the condenser.
그러므로 상대적으로 응축기로 흘러내리는 냉각수의 양이 감속하게 되어 응축기의 열교환 효율이 떨어지게 되고, 그에 따라 전체적인 공기조화기의 효율감소의 원인이 되는 것이다.Therefore, the amount of cooling water flowing down to the condenser is relatively reduced, thereby reducing the heat exchange efficiency of the condenser, thereby reducing the efficiency of the overall air conditioner.
따라서 본 고안은 상기와 같은 점을 고려하여 안출한 것으로, 특히 그 목적은 수중펌프로 부터 올려지는 물을 손실됨이 없이 응축기로 이동시킴으로써 응축기의 열교환효율을 향상시킬수 있는 수냉식 공기조화기의 열교환장치를 제공함에 있다.Therefore, the present invention has been devised in consideration of the above points, in particular, the purpose of the heat exchanger of the water-cooled air conditioner that can improve the heat exchange efficiency of the condenser by moving the water from the water pump to the condenser without loss In providing.
상기의 목적은 상승관의 상부에 접시형의 확산판을 구비하고 이를 송풍팬모터 축에 고정함으로써 달성될 수 있다.The above object can be achieved by providing a dish-shaped diffusion plate on top of the riser and fixing it to the blower fan motor shaft.
즉, 종래의 안내판의 형상을 접시형으로 구성하여서된 확산판을 구비하여 상승관으로 부터 토출되는 냉각수의 이동력에 대한 충격을 최소한으로 하고, 또한 확산판을 모터의 회전에 따라 회전시킴으로써 확산판에 접하는 냉각수에 원심력을 작용시켜 냉각수를 확산판의 외주단부 측에서 낙하시킴으로써 냉각수의 이동도중의 손실을 최소화 할수있게 된 것이다.That is, the conventional guide plate is provided with a diffuser plate configured in the shape of a plate to minimize the impact on the movement force of the cooling water discharged from the riser, and also rotates the diffuser plate by rotating the motor according to the rotation of the diffuser plate. By applying centrifugal force to the coolant in contact with the coolant, the coolant drops on the outer peripheral end side of the diffuser plate, thereby minimizing the loss of the coolant's movement.
이하 본 고안의 바람직한 일실시예를 첨부도면에 의거하여 좀더 구체적으로 설명하면 다음과 같다(제2도 참조).Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings (see FIG. 2).
전술한 바와 같은 종래의 수냉식 공기조화기의 열교환장치에 있어서, 상승관(130)의 상부에 접시형의 확산판(140)을 구비하고, 이 확산판(140)은 그 상부의 송풍팬 모터축(82)을 연장하여 너트(150)로서 고정되어 있다.In the heat exchanger of the conventional water-cooled air conditioner as described above, the plate-shaped diffuser plate 140 is provided on the upper part of the riser 130, and the diffuser plate 140 has a blower fan motor shaft thereon. The 82 is extended and fixed as the nut 150.
상기 너트(150) 제3도에서 나타낸 바와같이 일측으로만 조립이 가능하게 되고 타측은 유선형으로 형성하여 상승관(130)으로 부터 투출되는 냉각수(1)에 마찰저항을 최소화하여 확산판(140)면으로 안내하게 되어있다.As shown in FIG. 3, the nut 150 may be assembled to only one side, and the other side may be streamlined to minimize frictional resistance to the coolant 1 discharged from the riser 130. It is directed to the side.
미설명부호 100은 증발기이다.Reference numeral 100 is an evaporator.
이와같은 구성을 갖는 본 고안에 따른 수냉식 공기조화기의 열교환장치의 작용효과를 살펴보면, 수중펌프(20)의 작동에 의해 냉각수(1)가 상승관(130)을 통해 확산판(140)으로 투출되고, 이때 냉각수(1)는 너트(150)의 유선형면에 안내되며 확산판면으로 이동하고, 또한 확산판이 접시형으로 이루어져 있음에 따라 냉각수는 확산판면을 따라 이동하게 된다.Looking at the effect of the heat exchange device of the water-cooled air conditioner according to the present invention having such a configuration, by the operation of the submersible pump 20 the cooling water 1 is discharged to the diffusion plate 140 through the riser 130. In this case, the cooling water 1 is guided to the streamlined surface of the nut 150 and moves to the diffusion plate surface, and the cooling water moves along the diffusion plate surface as the diffusion plate is formed in a plate shape.
한편 확산판은 송풍팬 모터(80)에 의해 회전하게 되어 표면장력으로 인해 확산판에 일시 보유하게 되는 냉각수에 원심력을 부여함으로써 냉각수는 2차적인 힘을 부여받게 되어 확산판의 끝단까지 이동하게 되고 따라서 확산판(140)의 끝단 하부에 설치되는 응축기(50)상에 낙하하게 된다.On the other hand, the diffusion plate is rotated by the blower fan motor 80 to impart centrifugal force to the cooling water temporarily held in the diffusion plate due to the surface tension, and thus the cooling water is applied to the end of the diffusion plate. Therefore, it falls on the condenser 50 installed at the lower end of the diffusion plate 140.
그리고 제4도는 본 고안의 다른 실시예로서 송풍팬 모터축(82)에 접시형의 확산판(140)을 구비하되, 그 중앙하부로 유선형 돌출부(160)를 형성한 것으로서, 결국 너트와 확산판을 일체화 함으로써 부품수를 감소시킬수 있는 장점이 있다.And Figure 4 is provided with a plate-shaped diffuser plate 140 in the blower fan motor shaft 82 as another embodiment of the present invention, the streamlined protrusions 160 formed in the lower center of the end, the nut and the diffuser plate There is an advantage that can reduce the number of parts by integrating.
상술한 바와같이 본 고안은 냉각수를 접시형 확산판을 이용하여 냉각수의 손실을 최소하여 응축기로 이동시킬수 있게되어, 수중펌프의 효율향상을 기할수 있을뿐만 아니라, 특히 응축기에 냉각수의 공급이 늘어남에 따라 응축기의 열교환 성능이 향상되고 그러므로써 전제적인 공기조화기의 성능향상에도 크게 기여할수 있는 것이다.As described above, the present invention enables the cooling water to be moved to the condenser by minimizing the loss of the cooling water by using a dish-type diffusion plate, which not only improves the efficiency of the submersible pump, but also increases the supply of the cooling water to the condenser. Therefore, the heat exchange performance of the condenser is improved, and thus it can greatly contribute to the improvement of the overall air conditioner performance.
