본 발명은 태양열 난방기기의 태양열흡수판에 관한 것으로, 특히 알루미늄판에 상호 엇갈리게 반원형의 절곡부를 연속 반복 형성하여, 동관을 끼운뒤 강구가 동관을 강제 통과되게 하므로써, 알루미늄판과 동관이 밀착된 태양열흡수판을 제조하고자 발명한 태양열흡수판 및 그 제조방법에 관한 것이다.The present invention relates to a solar heat absorbing plate of a solar heating apparatus, and in particular, the semi-circular bent portion is repeatedly formed alternately on the aluminum plate, so that the steel ball is forced through the copper tube after inserting the copper tube, so that the aluminum plate and the copper tube are in close contact with each other. The present invention relates to a solar heat absorbing plate and a method for manufacturing the same.

종래 태양열흡수판의 제조방법은 제1도와 같이 2장의 알루미늄판(1a)(1b) 사이와 동관(2)을 끼워 넣고 압착로울러(5a)(5b)를 이용하여 알루미늄과 동관을 일체로 납작하게 성형하여 평판(4')을 제작하며, 그 평판(4')을 적절한 크기로 절단한다.Conventionally, the solar heat absorbing plate is manufactured by sandwiching the copper tube 2 between two aluminum plates 1a and 1b as shown in FIG. 1 and flattening the aluminum and the copper tube together using a compression roller 5a and 5b. The flat plate 4 'is manufactured by molding, and the flat plate 4' is cut to an appropriate size.

그후, 납작하게 성형된 동관에 초고압으로 공기를 주입시켜 동관을 확관시키므로써 유로가 형성되게 하여 태양열흡수판(4)을 제2도와 같이 제조하였다.Thereafter, air was injected into the flat copper tube at a very high pressure to expand the copper tube to form a flow path, thereby manufacturing a solar heat absorbing plate 4 as shown in FIG.

그러나, 제3도(a)와 같은 동관(2)의 원형 상태에서 (b)와 같이 압착로울러(5a)(5b)에 의해 납작하게 성형한뒤 (c)와 같이 초고압으로 공기를 주입시켜 동관(2)을 확관시킬때 접혀진 부분에 기계적 스트레스가 발생하게 되어 알루미늄과 동관의 접합부위에서 균열이 발생하게 되었으며, 태양열흡수판(4)끼리의 연결 작업시 알루미늄과 동은 서로 다른 재질이므로 용접작업이 매우 어려운 문제점이 있었다.However, in the circular state of the copper tube 2 as shown in FIG. 3 (a), it is flatly formed by the pressing rollers 5a and 5b as shown in (b), and then air is injected at a very high pressure as shown in (c). When expanding (2), mechanical stress occurred on the folded part, causing cracks at the junction between aluminum and copper pipes. There was a very difficult problem.

본 발명은 이러한 종래의 결점을 해결하고자 한 것으로, 알루미늄판에 상호 엇갈리게 반원형의 절곡부를 연속반부 형성하여 동관을 끼운뒤 강구가 동관을 강제 통과되게 하여 확산시키므로써 알루미늄판과 동관을 밀착시켜 태양열흡수판을 제조하기 때문에 동관에 어떠한 기계적 변형을 주지 않아 동관의 균열방지 및 유체의 손실을 없애고자 한 것이다.The present invention has been made to solve the above-mentioned drawbacks, the semi-circular bent portion of the aluminum plate to form a continuous half cross-inserted copper tube after the copper tube is forced to pass through the copper tube diffused by closely adhering the aluminum plate and copper tube to absorb solar heat. Since the plate is manufactured, no mechanical deformation is given to the copper tube, so that the copper tube is prevented from cracking and fluid loss.

이하 본 발명을 첨부도면에 의하여 상세히 설명한다.Hereinafter, the present invention will be described in detail by the accompanying drawings.

도면 제4도 내지 제6도는 본 발명의 실시예로써, 알루미늄판(1)에 동관(2)이 끼워질 수 있도록 반원형의 절곡부(11)를 상호 엇갈리게 상, 하로 연속 반복하여 돌출형성하고, 그 상, 하로 돌출절곡된 절곡부(11)에 의해 형성된 동관삽입구로 동관(2)을 끼운다.Figures 4 to 6 is an embodiment of the present invention, the semi-circular bent portion 11 to be alternately alternately projected to form a semi-circular bending portion 11 so as to be fitted to the aluminum plate (1), The copper tube 2 is inserted into the copper tube insertion opening formed by the bent portion 11 protruding bent upward and downward.

상기 알루미늄판(1)은 금형으로 성형하며, 상기 절곡부(11)를 다수열로 성형할 수도 있다.The aluminum plate 1 is molded in a mold, and the bent portion 11 may be molded in a plurality of rows.

상기와 같이 동관(2)이 끼워진 상태에서 강구(3)를 동관(2)의 일단에서 타단으로 특수펌프를 이용하여 강제로 밀어낸다.As described above, the steel ball 3 is forcibly pushed from one end of the copper pipe 2 to the other end by using a special pump while the copper pipe 2 is fitted.

상기 강구(3)이 크기는 동관(2)이 절곡부(11)에 완전히 밀착될 수 있을 정도의 크기이면 무방하다.The steel ball 3 may have a size such that the copper tube 2 can be completely adhered to the bent portion 11.

따라서, 강구(3)가 강제로 동관(2)을 통과하게 되면서 동관(2)을 확관시키게 되고, 동관(2)의 확관으로 절곡부(11)와 동관(2)이 제6도와 같이 완전히 밀착하여 태양열흡수판(4)이 제조되는 것이다.Therefore, the steel ball 3 is forced through the copper tube 2 to expand the copper tube 2, and the bent portion 11 and the copper tube 2 are completely in close contact with each other as shown in FIG. 6 by the expansion of the copper tube 2. The solar heat absorbing plate (4) is to be manufactured.

이때, 확관된 동관(2)의 두께는 변화없으나, 길이상으로 약간 신장하게 된다.At this time, the thickness of the expanded copper tube (2) is not changed, but is slightly elongated on the length.

또, 본 발명의 태양열흡수판(4)은 알루미늄판(1)을 1장을 사용하므로 재료절감을 도모할 수가 있는 것이다.In addition, since the solar heat absorbing plate 4 of the present invention uses one aluminum plate 1, the material can be reduced.

이와 같이 본 발명은 강구슈팅(ball shooting) 공법을 이용하여 태양열흡수판을 제조하므로써 동관에 어떠한 기계적 변형을 주지 않고 그대로의 동관을 유지하므로 동관에 균열이 발생할 염려가 없어 유로내의 유체손실을 없앨 수가 있는 것이다.As described above, the present invention maintains the copper tube as it is without any mechanical deformation in the copper tube by manufacturing a solar heat absorbing plate using a ball shooting method, so there is no fear of cracking in the copper tube, thereby eliminating fluid loss in the flow path. It is.
