Description
본 고안은 열교환장치에 관한 것으로써, 특히 열교환효율이 향상되도록 방열관을 이중구조로 개선한 열교환장치에 관한 것이다.The present invention relates to a heat exchanger, and more particularly, to a heat exchanger having an improved heat dissipation tube in a double structure to improve heat exchange efficiency.

Since it is easy to cool, there is a problem that the heat exchange efficiency is lowered.
본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로써, 열교환효율이 향상되도록 그 구조가 개선된 열교환장치를 제공하는 데 그 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a heat exchanger having an improved structure to improve heat exchange efficiency.

이하 첨부된 도면을 참조하면서 본 고안에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 고안 열교환장치를 나타낸 도 2 내지 도 4를 참조하면, 이 열교환장치는 전원의 공급으로 발열되는 열선(20)과, 상기 열선(20)과 전기적으로 절연되면서 열선(20) 주위를 포위하는 내부방열관(30)과, 상기 내부방열관(30)을 포위하는 외부방열관(40)과, 상기 외부방열관(40)의 외주면에 일정간격으로 접촉설치되는 복수의 방열휜(50)을 구비한다.2 to 4 illustrating the inventive heat exchanger, the heat exchanger includes a heating wire 20 that generates heat by supply of power and an inner space surrounding the heating wire 20 while being electrically insulated from the heating wire 20. It is provided with a heat dissipation tube 30, an outer heat dissipation tube 40 surrounding the inner heat dissipation tube 30, and a plurality of heat dissipation fins 50 installed in contact with the outer circumferential surface of the outer heat dissipation tube 40 at regular intervals. do.
상기 외부방열관(40)의 양단부는 결합공(61a)(62a)이 형성된 지지대(61)(62)에 결합지지되며, 지지대(61)(62)에 일정간격으로 복수로 지지될 수 있다.Both ends of the outer heat dissipation tube 40 may be coupled to and supported by the supports 61 and 62 in which the coupling holes 61a and 62a are formed, and may be plurally supported by the supports 61 and 62 at a predetermined interval.
또한, 상기 외부방열관(40)은 중공의 타원형 단면으로 형성되어서, 유체와의 열교환면적이 증대되도록 하였다.In addition, the external heat dissipation tube 40 is formed in a hollow elliptical cross section, so that the heat exchange area with the fluid is increased.
또한, 도 5에 도시된 바와 같이, 상기 외부방열관(40)의 내부에는 상기 내부 방열관(30)을 복수로 채용할 수도 있다. 이 경우 열교환효율을 더욱 향상시킨다.In addition, as illustrated in FIG. 5, a plurality of internal heat dissipation tubes 30 may be employed inside the external heat dissipation tubes 40. In this case, the heat exchange efficiency is further improved.
상술한 바와 같은 본 고안은 전원의 공급에 의해서 열선(20)이 가열되고, 이에 따라서 내부방열관(30) 및 외부방열관(40)이 순차적으로 가열되어서, 외부방열관(40) 및 방열휜(50)을 통하여 외부로 열이 방출된다.In the present invention as described above, the heating wire 20 is heated by the supply of power, and thus the inner heat dissipation tube 30 and the outer heat dissipation tube 40 are sequentially heated, and thus, the outer heat dissipation tube 40 and the heat dissipation beam. Heat is released to the outside through (50).
이와 같이 외부방열관(40) 및 방열휜(50)을 통하여 외부로 열이 방출되는 동안 도 3에 도시된 바와 같이, 냉유체를 상기 외부방열관(40) 및 방열휜(50)에 유체를 접촉하여 경유시키면 온유체로 열교환이 이루어진다.As shown in FIG. 3 while the heat is discharged to the outside through the external heat dissipation tube 40 and the heat dissipation fan 50 as described above, a cold fluid is applied to the external heat dissipation pipe 40 and the heat dissipation fan 50. When contacted and diesel, heat exchange is performed with warm fluid.
이와 같이 냉유체가 온유체로 열교환이 이루어지는 동안, 냉유체가 열선(20) 및 내부방열관(30)에 직접 접촉되지 아니하고 외부방열관(40)에 접촉되어 열교환이 이루어지게 되므로, 열선(20) 및 내부방열관(30)의 발열이 안정적으로 이루어지게하여 계속적인 열교환효율이 향상되게 된다.As such, while the cold fluid is heat-exchanged with the warm fluid, the cold fluid is not directly in contact with the heating wire 20 and the inner heat dissipation tube 30, but is in contact with the outer heat dissipation tube 40, so that heat exchange is performed. And heat generation of the inner heat dissipation tube 30 is made to be stable to improve the continuous heat exchange efficiency.
더욱이, 도 5에 도시된 바와 같이 외부방열관(40) 내에 열선(20) 및 내부방열관(30)이 복수로 채용되는 경우에는 열교환효율이 더욱 향상되게 된다.Furthermore, as shown in FIG. 5, when a plurality of heat wires 20 and internal heat dissipation tubes 30 are employed in the external heat dissipation tube 40, heat exchange efficiency is further improved.
상술한 바와 같은 본 고안은 본원의 정신과 범위를 이탈함이 없이 상기 실시예에 한정되지 아니하고 많은 변형을 가하여 실시될 수 있다.The present invention as described above is not limited to the above embodiments without departing from the spirit and scope of the present application can be carried out with a number of modifications.
상술한 바와 같은 본 고안은 방열휜이 외주면에 형성된 외부방열관(40)내에 열선(20) 및 내부바열관(30)을 채용함으로써, 열선(20) 및 내부방열관(30)의 방열을 안정적으로 하여 외부방열관과 방열휜을 통한 열교환효율을 향상시킨다.As described above, the present invention employs the heating wire 20 and the inner bar heat pipe 30 in the outer heat pipe 40 formed on the outer circumferential surface of the heat dissipation to thereby stabilize heat dissipation of the heat wire 20 and the inner heat pipe 30. This improves the heat exchange efficiency through the external heat dissipation tube and the heat dissipation fan.
