이하, 첨부된 도면에 따라서 본 고안을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안의 일 실시예에 따른 냉각장치를 보여주는 단면도이다.1 is a cross-sectional view showing a cooling apparatus according to an embodiment of the present invention.
상부가 폐쇄되고 하부가 개구된 중공형의 하우징(100)은 하부 캡(108)과 분리 가능하게 결합된다. 바람직하게, 하부 캡(108)은 열전도성이 우수한 재질로 만들어질 수 있다.The hollow housing 100 with the top closed and the bottom open is detachably coupled to the bottom cap 108. Preferably, the lower cap 108 may be made of a material having excellent thermal conductivity.
하우징(100)은 원적외선 방사 물질로 이루어지는 것이 바람직하며, 특히, 세라믹이나 황토재질은 원적외선을 방사하면서도 수분을 일정량 함유할 수 있어 냉각과정에서 발생될 수도 있는 수분을 흡수할 수 있어 더욱 바람직하다. The housing 100 is preferably made of a far-infrared radiating material. In particular, the ceramic or ocher material may contain a certain amount of moisture while emitting far-infrared rays, and thus may absorb moisture that may be generated during the cooling process.
하부 캡(108)의 표면에는 가장자리로부터 이격되어 가장자리를 따라 돌기(107)가 형성되고, 돌기(107)의 내측 저면에는 외부와 연통되는 배수공(109)이 형성된다. 배수공(109)은 배수용 튜브(110)에 연결된다.On the surface of the lower cap 108, projections 107 are formed along the edges spaced from the edges, and drain holes 109 are formed on the inner bottom of the projections 107 to communicate with the outside. The drain hole 109 is connected to the drain tube 110.
하우징(100)의 내부에는 중공형의 절연시트(104)가 돌기(107) 내측으로 강제 압입되어 세워지며, 절연시트(104)와 하우징(100)의 내측면 사이에 히터선(106)이 권취된다.Inside the housing 100, a hollow insulating sheet 104 is forcedly pressed into the protrusion 107, and a heater wire 106 is wound between the insulating sheet 104 and the inner surface of the housing 100. do.
절연시트(104)의 내부에는 실린더 형상의 냉각 포스트(102)가 배치된다. 냉각 포스트(102)는 열전도성이 우수한 재질로 이루어지며, 하단에서 하부 캡(108)에 용접 등의 방법으로 고정된다.A cylindrical cooling post 102 is disposed inside the insulating sheet 104. The cooling post 102 is made of a material having excellent thermal conductivity, and is fixed to the lower cap 108 by welding or the like at the bottom.
하부 캡(108)의 이면에는 펠티어소자(200)의 일면(냉각면)이 부착되고, 펠티어소자(200)의 타면(열방출면)에는 방열핀(300)이 부착되며, 방열핀(300)에는 냉각팬(400)이 설치된다.One surface (cooling surface) of the Peltier element 200 is attached to the rear surface of the lower cap 108, and a heat dissipation fin 300 is attached to the other surface (heat dissipation surface) of the Peltier element 200, and a cooling fan is attached to the heat dissipation fin 300. 400 is installed.
바람직하게, 하부 캡(108)과 방열핀(300) 사이에는 집수 플레이트(210)가 설치되며, 집수 플레이트(210)의 일측 단부는 펠티어소자(200)보다 외측으로 돌출된다.Preferably, a collecting plate 210 is installed between the lower cap 108 and the heat dissipation fin 300, and one end of the collecting plate 210 protrudes outward from the Peltier element 200.
이와 같은 구조를 갖는 냉각장치의 동작에 대해 설명한다.The operation of the cooling device having such a structure will be described.
먼저, 펠티어소자(200)에 전원이 인가되면, 펠티어 효과에 의해 펠티어소자(200)의 표면은 냉각되고 이면은 열을 방출한다.First, when power is applied to the Peltier element 200, the surface of the Peltier element 200 is cooled by the Peltier effect and the back surface releases heat.
따라서, 펠티어소자(200)의 표면 - 하부 캡(108) - 냉각 포스트(102)를 통한 열전달 경로가 형성됨으로써 냉각 포스트(102)에 의해 하우징(100)이 냉각되며, 이에 따라 하우징(100)에 접촉되는 곡물, 예를 들어, 쌀이 냉각된다.Thus, the heat transfer path through the surface-lower cap 108-cooling post 102 of the Peltier element 200 is formed, thereby cooling the housing 100 by the cooling post 102, and thus the housing 100 The grains contacted, for example rice, are cooled.
또한, 펠티어소자(200)의 이면 - 방열핀(300) - 냉각팬(400)으로 형성되는 경로를 통하여 펠티어소자(200)로부터 방출되는 열을 배출하게 된다.In addition, the heat discharged from the Peltier element 200 is discharged through a path formed by the back surface of the Peltier element 200-the heat dissipation fin 300-the cooling fan 400.
이와 같은 냉각이 진행되면서, 예를 들어, 하우징(100) 내에 설치된 습도센서(미도시)에 의해 일정한 레벨 이상의 습도가 감지되면, 냉각 포스트(102)의 외표면에 결로가 발생한 것으로 판단하여 결로제거 작업을 수행한다.As the cooling proceeds, for example, when a humidity level or higher is sensed by a humidity sensor (not shown) installed in the housing 100, it is determined that condensation has occurred on the outer surface of the cooling post 102 to remove condensation. Do the work.
즉, 히터선(106)에 전원을 인가하면, 히터선(106)이 가열되고 이 열에 의해 냉각 포스트(102)의 외표면에 형성된 결로가 녹아 물로 변화하면서 냉각 포스트(102)를 타고 흘러내린다.That is, when power is applied to the heater wire 106, the heater wire 106 is heated, and the condensation formed on the outer surface of the cooling post 102 melts by this heat and flows through the cooling post 102 while changing to water.
냉각 포스트(102)의 하단에는 하부 캡(108)과 돌기(107)에 의해 공간이 형성되며, 흘러내리는 물은 이 공간에 집수된 후, 배수공(109)를 통해 외부로 배출된다.A space is formed at the lower end of the cooling post 102 by the lower cap 108 and the protrusion 107, and the flowing water is collected in the space and then discharged to the outside through the drain hole 109.
이때, 배수공(109)에 연결된 배수용 튜브(110)를 통하여 집수 플레이트(210)에 집수된다. 결과적으로, 집수된 물은 펠티어소자(200)의 이면으로부터 방출되어 집수 플레이트(210)에 전달되는 열에 의해 증발된다.At this time, the water collecting plate 210 is collected through the drainage tube 110 connected to the drain hole 109. As a result, the collected water is discharged from the back surface of the Peltier element 200 and evaporated by the heat transferred to the collecting plate 210.
이상에서는 일 실시예를 중심으로 설명하였지만 당업자의 수준에서 다양한 변경이 가능하다.Although the above has been described with reference to one embodiment, various changes are possible at the level of those skilled in the art.
예를 들어, 집수 플레이트를 별도로 구비하지 않고 펠티어소자와 대면하는 방열핀의 면을 가공하여 집수홈을 형성하여 이 집수홈에 물이 집수되도록 하는 것도 가능하다.For example, it is also possible to form a water collecting groove by processing the surface of the heat dissipation fin facing the Peltier element without separately providing a water collecting plate so that water is collected in the water collecting groove.
따라서, 본 고안의 권리범위는 상기한 실시예에 한정되어 해석되어서는 안되고 이하에 기재되는 실용신안등록청구범위에 의해서 해석되어야 할 것이다.Therefore, the scope of the present invention should not be construed as limited to the above embodiment but should be interpreted by the utility model registration claims described below.
이상에서 설명한 바와 같이, 본 고안에 따르면 구조가 간단하기 때문에 고장이 적다는 이점이 있다.As described above, according to the present invention, since the structure is simple, there is an advantage that the failure is small.
또한, 이 구성에 적합한 결로방지구조를 제공함으로써 결로에 의한 수분이 하우징을 통과하여 곡물에 전달되는 것을 방지할 수 있다.In addition, by providing a condensation preventing structure suitable for this configuration, it is possible to prevent moisture due to condensation from passing through the housing to the grain.
