이는 도 1에서 보는 바와 같이 상부에 온수 배출파이프(11)가 연결되고, 하부에 냉수 유입파이프(12)가 연결되며, 바닥에 드레인 밸브(13)가 연결된 채 보온단열재(14)로써 둘러 싸여진 축열탱크(10), 상기 축열탱크의 내부에 구비된 열교환기(22)와, 상기 열교환기의 내부로 액상의 열매체가 순환하도록 연결하여 옥외에 노출시킨 태양열 집열용 집열기(21)와, 상기 열매체를 강제 이동시키기 위한 펌프(24)로 이루어진 열매체 가동수단(20), 상기 축열탱크(10)의 내부에 마련한 보조가열수단(30)을 포함하여 이루어진다. 1, the heat storage discharge pipe 11 is connected to the upper portion, the cold water inlet pipe 12 is connected to the lower portion, and the heat storage is surrounded by the heat insulating material 14 while the drain valve 13 is connected to the bottom. Tank 10, the heat exchanger 22 provided in the heat storage tank, the solar heat collector (21) connected to the liquid heat medium to circulate to the inside of the heat exchanger exposed to the outdoors and the heat medium It comprises a heating medium moving means 20 consisting of a pump 24 for forced movement, the auxiliary heating means 30 provided in the heat storage tank 10.

In addition, the heat medium moving means 20 is provided with a heat medium expansion tank 23 between the heat exchanger 22 and the pump 24 so that the end of the heat exchanger 22 is submerged in the heat medium therein.

At 40, the pump 24 is driven only when the temperature at the collector 21 side is high compared to the temperature value detected by another temperature sensor 28 provided at the lower end of the heat exchanger 22.

펌프(24)가 구동되면 열매체가 집열기(21)로부터 축열탱크(10) 내부의 열교환기(22) 속으로 흐르게 되고, 열교환기(22)에서는 다음의 열매체용 팽창탱크(23)로 보내진다. When the pump 24 is driven, the heat medium flows from the collector 21 into the heat exchanger 22 inside the heat storage tank 10, and the heat exchanger 22 is sent to the next expansion tank 23 for the heat medium.

상기 팽창탱크(23) 속에서는 열매체의 내부에 포함되어 있던 공기가 상측으로 모아지고, 모아진 다음에는 열매체 팽창탱크(23a)의 상부를 거쳐 체크밸브를 통해 밖으로 배출된다.In the expansion tank 23, the air contained in the heat medium is collected upwards, and after being collected, the air is discharged out through the check valve via the upper portion of the heat medium expansion tank 23a.

따라서 기포가 제거된 열매체는 펌프(24)의 구동에 따라 다시 집열기(21)로 보내지며, 집열기에서 다시 태양열을 축적하여 열교환기(22)로 순환하게 되는 것이다. Therefore, the heat medium from which bubbles are removed is sent to the collector 21 again according to the driving of the pump 24, and the solar medium accumulates solar heat again in the collector to circulate to the heat exchanger 22.

상기와 같은 작동되면, 집열기(21)로써 축적한 태양열이 축열탱크(10) 내부에서 열교환기(22)를 통해 물을 가열할 수 있게 되는 것이다. When the operation as described above, the solar heat accumulated by the collector 21 is able to heat the water through the heat exchanger 22 in the heat storage tank (10).

그리고 본 발명의 구성에 따르면, 상기한 열교환기(22) 속에 도 3에서 보는 바와 같이 축열탱크(10) 내부의 물이 순환할 수 있도록 물 순환 파이프(10a)가 내 장되어 있고, 순환 펌프(10b)로써 강제 순환시키고 있는 바, 태양열 집열기(21)에서 수집된 열이 축열매체로 전달된 후, 다시 순환 파이프(10a) 속의 물로 전달되며, 따라서 축열탱크(10) 내부의 물이 전체적으로 가열되는 것이다. According to the configuration of the present invention, the water circulation pipe 10a is built in the heat exchanger 22 so that the water in the heat storage tank 10 can circulate as shown in FIG. 10b), the heat collected by the solar collector 21 is transferred to the heat storage medium, and then is transferred to the water in the circulation pipe 10a, so that the water inside the heat storage tank 10 is heated as a whole. will be.

이와 같이 물 순환 파이프(10a)와 열교환기(22)의 내부에는 축열매체가 어느정도의 유속을 가지고 흐르고 있기 때문에 이물질이 축척되는 일이 없으며, 부식이 예방될 수 있다. As such, since the heat storage medium flows with a certain flow rate in the water circulation pipe 10a and the heat exchanger 22, foreign matters do not accumulate and corrosion can be prevented.

위에서 상세히 설명한 바와 같은 본 발명은 태양열 집열기로부터 집열된 열 에너지가 열교환기의 축열탱크 물속으로 전달되도록 하되, 상기 열교환기가 그 물 속에 잠기지 않고 별도의 물순환 파이프를 내장한 채 열매체의 흐름이 지속되도록 구성되어 있기 때문에 부식을 유발하는 이물질이 부착되지 못하게 된다. The present invention as described in detail above allows the heat energy collected from the solar heat collector to be transferred to the heat storage tank water of the heat exchanger, so that the heat medium flows without the heat exchanger being submerged in the water and having a separate water circulation pipe embedded therein. This prevents the attachment of foreign matters that cause corrosion.

따라서 이물질이 파이프의 내 외측면에 부착 또는 축적되지 않으므로 부식이 예방되고, 아울러 열교환기 내에 물순환 파이프를 내장함으로써 탁월한 열전달 효과를 얻을 수가 있으며, 열교환기 및 전체 보일러의 수명을 크게 연장시킬 수 있는 장점을 가지는 것이다. Therefore, since foreign matter does not adhere to or accumulate on the inner and outer surfaces of the pipe, corrosion is prevented, and an excellent heat transfer effect can be obtained by embedding a water circulation pipe in the heat exchanger, and can greatly extend the life of the heat exchanger and the entire boiler. It has an advantage.
