And a lens unit 124 condensing into 102, and a predetermined space 126 may be formed inside the secondary lens 120.

따라서 본 발명에 따른 태양전지 어셈블리(100)는 2차렌즈(120)의 커버부(122)에 의해 태양전지(102)와 회로기판(104)이 외부로부터 보호될 수 있기 때문에 태양전지(102)와 회로기판(104)을 보호하기 위한 별도의 구성이 필요없으며 따라서 그만큼 전체적인 구성과 조립을 간단히 할 수 있게 된다. Therefore, in the solar cell assembly 100 according to the present invention, the solar cell 102 and the circuit board 104 may be protected from the outside by the cover part 122 of the secondary lens 120. And a separate configuration for protecting the circuit board 104 is not required, and thus the overall configuration and assembly can be simplified.

히트파이프(110) 상부에는 길이방향으로 길게 형성되는 홈(114)이 구비되고, 회로기판(104)은 홈(114)에 구비됨이 바람직하다. 그러면 2차렌즈(120)를 회로기판(104) 상부에 구비시키기가 용이해질 수 있다.It is preferable that the groove 114 is formed to be elongated in the longitudinal direction on the heat pipe 110 and the circuit board 104 is provided in the groove 114. Then, the secondary lens 120 may be easily provided on the circuit board 104.

도 5는 태양전지 어셈블리가 베이스플레이트에 결합된 상태를 나타내는 도면이고, 도 6은 태양전지 어셈블리와 베이스플레이트의 분해 사시도이다. 5 is a view showing a state in which the solar cell assembly is coupled to the base plate, Figure 6 is an exploded perspective view of the solar cell assembly and the base plate.

도 2, 도 5 및 도 6을 참조하면, 베이스플레이트(30)에는 길이방향으로 길게 이루어지는 히트파이프(110)가 안착하는 안착부(33)가 가로방향(x)으로 길게 구비되는데, 이러한 안착부(33)는 베이스플레이트(30) 상부에 돌출형성되는 한 쌍의 안착부형성리브(32)가 가로방향(x)으로 길게 형성됨으로써 구비될 수 있다. 2, 5 and 6, the base plate 30 is provided with a seating portion 33 in which the heat pipe 110, which is formed in the longitudinal direction, is mounted in the horizontal direction (x). Reference numeral 33 may be provided by a pair of seating forming ribs 32 protruding from the base plate 30 is formed long in the horizontal direction (x).

또한 베이스플레이트(30)의 하부에는 방열리브(31)가 돌출형성될 수 있다. In addition, a heat dissipation rib 31 may protrude from a lower portion of the base plate 30.

따라서 본 발명에 따른 고집광형 태양전지모듈(10)은 태양전지(102)가 장착된 회로기판(104)을 자체로 방열기능을 가지는 길이방향으로 길게 이루어지는 히트파이프(110) 바로 위에 부착결합시키고, 이러한 히트파이프(110)를 하부에 방열리브(31)가 형성된 베이스플레이트(30) 바로 위에 결합시키기 때문에, 태양전지(102)에서 발생하는 열은 히트파이프(110)에 의해 넓은 영역으로 효과적으로 방열된 후 순차적으로 베이스플레이트(30)에 의해 외부로 보다 효과적으로 방열될 수 있으며 따라서 방열효과를 극대화시킬 수 있게 된다. Therefore, the highly-concentrated solar cell module 10 according to the present invention attaches and bonds the circuit board 104 on which the solar cell 102 is mounted directly on the heat pipe 110 which is elongated in the longitudinal direction having a heat dissipation function. Since the heat pipe 110 is coupled directly above the base plate 30 having the heat dissipation ribs 31 formed therein, heat generated from the solar cell 102 is effectively dissipated to a large area by the heat pipe 110. After the sequential base plate 30 can be more effectively radiated to the outside, thereby maximizing the radiating effect.

안착부형성리브(32)의 내측면에는 안착부(33)에 안착된 히트파이프(110)를 고정하는 내측걸림턱(34)이 형성될 수 있다. 그러면 히트파이프(110)를 안착부(33)에 억지끼움시키거나 또는 베이스플레이트(30)를 살짝 구부린 상태에서 히트파이프(110)를 안착부(33)에 결합시키면, 히트파이프(110)는 양측이 내측걸림턱(34)에 걸림된 상태로 고정될 수 있다. 따라서 본 발명에 따른 모듈(10)은 태양전지 어셈블리(100)를 별도의 나사결합없이도 쉽게 베이스플레이트(30)에 결합 고정시킬 수 있어서 전체적인 구성과 조립을 간단히 할 수 있게 된다. An inner locking jaw 34 may be formed on the inner surface of the seating forming rib 32 to fix the heat pipe 110 seated on the seating portion 33. Then, if the heat pipe 110 is forcibly fitted to the seating portion 33 or the heat pipe 110 is coupled to the seating portion 33 while the base plate 30 is slightly bent, the heat pipe 110 is formed on both sides. The inner locking jaw 34 can be fixed in a locked state. Therefore, the module 10 according to the present invention can easily fix and fix the solar cell assembly 100 to the base plate 30 without a separate screw coupling to simplify the overall configuration and assembly.

안착부(33)와 히트파이프(110) 사이에는 TIM(Thermal Interface Material) 소재로 이루어지는 열전도성 밀착부재 시트(70)가 개재될 수 있다. A thermally conductive adhesive member sheet 70 made of a thermal interface material (TIM) may be interposed between the seating portion 33 and the heat pipe 110.

On the other hand, the base plate 30 has a predetermined width in the longitudinal direction (y) and is arranged in the longitudinal direction (y) to combine, a plurality of pieces (base) base plate 40 each screwed to the vertical plate (50) It may be made of. In addition, a heat dissipation rib 31 is formed at each lower portion of the base plate 40, and coupling ribs 35 are formed at both ends thereof to engage with adjacent pieces of base plate 40, and a vertical plate 50 is formed at the upper end thereof. At least one screw coupling rib 36 and a pair of seating forming ribs 32 for screwing together may be formed. In the drawings, an embodiment in which one pair of seating ribs 32 is formed on one piece base plate 40 is illustrated, but the present invention is not limited thereto, and a pair of seating ribs 32 is provided. Two or more may be formed, and thus, the solar cell assembly 100 arranged in the horizontal direction (x) may be arranged in the longitudinal direction (y) in one piece base plate 40.

따라서 각각의 조각베이스플레이트(40)는 방열리브(31), 한 쌍의 안착부형성리브(32), 결합리브(35), 나사결합리브(36) 등에 의해 강성이 향상될 수 있으며, 방열리브(31)에 의해 외부와 접촉하는 면적이 넓어지게 되어 밀폐된 프레임 내부에서 발생하여 조각베이스플레이트(40)로 전달된 열을 원활하게 외부로 배출시킬 수 있으며, 또한 결합리브(35)와 나사결합리브(36)에 의해 얇은 판재로 이루어지는 조각베이스플레이트(40)의 결합 및 조립이 쉽게 이루어질 수 있다. Therefore, each piece base plate 40 can be improved in rigidity by the heat dissipation rib 31, a pair of seating forming ribs 32, the coupling rib 35, the screw coupling rib 36, etc. The area in contact with the outside is widened by the 31 to generate the inside of the sealed frame to smoothly discharge the heat transferred to the piece base plate 40 to the outside, and also coupled to the coupling rib 35 and screwed The rib 36 may be easily assembled and assembled with the piece base plate 40 made of a thin plate.

On the other hand, the highly focused solar cell module 10 according to the present invention may further include a fixed elastic member 60 coupled to the pair of mounting portion forming ribs 32 in a state in which the secondary lens 120 is compressed. have.

그리고 이와 같이 고정탄성부재(60)가 2차렌즈(120)를 압착하게 되면, 그와 동시에 히트파이프(110)를 압착하게 되므로, 2차렌즈(120)를 베이스플레이트(30)에 고정시키기가 용이할 뿐만 아니라 2차렌즈(120)와 함께 히트파이프(110)도 보다 견고하게 고정할 수 있게 된다. 또한 고정탄성부재(60)의 압착에 의해 회로기판(104)과 히트파이프(110)의 접촉 및 히트파이프(110)와 베이스플레이트(30)의 접촉이 보다 밀착될 수 있어서 그에 따라 방열효과가 더욱 극대화시킬 수 있게 된다. When the fixed elastic member 60 compresses the secondary lens 120 as described above, the heat pipe 110 is compressed at the same time, so that the secondary lens 120 is fixed to the base plate 30.

도 7은 도 5의 'A'영역 확대도이고, 도 8은 도 5의 'B'영역 확대도이다.7 is an enlarged view of region 'A' of FIG. 5, and FIG. 8 is an enlarged view of region 'B' of FIG. 5.

도 4, 도 7 및 도 8을 참조하면, 본 발명에 따른 리본와이어(130)는 히트파이프(110)에 구비된 복수개의 태양전지(102)가 서로 통전되도록 하는 제1리본와이어(140)와, 히트파이프(110)의 양측 단부에 구비되는 제2리본와이어(150)를 포함할 수 있다. 4, 7 and 8, the ribbon wire 130 according to the present invention may include a first ribbon wire 140 through which a plurality of solar cells 102 provided in the heat pipe 110 are energized with each other. The second ribbon wire 150 may be provided at both ends of the heat pipe 110.

제1리본와이어(140)는 제1길이부(142)와, 제1길이부(142)의 양측에서 하방으로 연장되는 한 쌍의 단차부(144)와, 단차부(144)로부터 연장되는 한 쌍의 플랜지부(146)를 포함하여 이루어질 수 있다. The first ribbon wire 140 extends from the first length portion 142, a pair of stepped portions 144 extending downward from both sides of the first length portion 142, and the stepped portion 144. It may comprise a pair of flange portions 146.

한 쌍의 플랜지부(146)는 회로기판(104)에 연결되는 부위로서, 회로기판(104)과 납땜 등에 의해서 부착결합될 수 있으며, 부착결합된 이후에는 제1리본와이어(140)를 지지한다. 즉, 제1리본와이어(140)는 한 쌍의 플랜지부(146)가 서로 인접하여 이격된 회로기판(104)에 각각 납땜(soldering), 용접(welding) 등에 의해 부착결합됨에 따라 자체적으로 고정된 구조를 가지게 된다. 제1리본와이어(140)는 자체적으로 더욱 안정된 상태로 고정될 수 있고, 충분한 통전능력을 갖도록 전체적으로 소정의 폭을 가지는 플레이트 형태로 이루어짐이 바람직하다. The pair of flange portions 146 is a portion connected to the circuit board 104, and may be attached to the circuit board 104 by soldering or the like. After the attachment, the pair of flange parts 146 may support the first ribbon wire 140. . That is, the first ribbon wire 140 is fixed by itself as the pair of flange portions 146 are attached to each other by soldering, welding, or the like, to the circuit board 104 spaced apart from each other. It has a structure. The first ribbon wire 140 may be fixed in a more stable state on its own, and is preferably made of a plate shape having a predetermined width as a whole to have sufficient current carrying capacity.

또한 제1리본와이어(140)는 한 쌍의 플랜지(146)와 한 쌍의 단차부(144)에 의해서 제1길이부(142)가 바닥으로부터 상방으로 소정거리 이격된 상태를 유지할 수 있으므로, 제1길이부(142)의 절연을 위한 별도의 구성이 필요없으며 따라서 그만큼 전체적인 구성과 조립을 간단히 할 수 있다. In addition, the first ribbon wire 140 may maintain a state in which the first length portion 142 is spaced apart from the bottom by a predetermined distance by the pair of flanges 146 and the pair of stepped portions 144. There is no need for a separate configuration for the insulation of the length unit 142, so that the overall configuration and assembly can be simplified.

제2리본와이어(150)는 회로기판(104)에 연결되는 플랜지부(156), 플랜지부(156)에 연결되는 단차부(154), 단차부(154)에 연결되는 제2길이부(156) 및 제2길이부(156)의 단부로부터 상방으로 절곡되는 절곡부(158)를 포함하여 이루어질 수 있다.The second ribbon wire 150 has a flange portion 156 connected to the circuit board 104, a stepped portion 154 connected to the flange portion 156, and a second length portion 156 connected to the stepped portion 154. ) And a bent portion 158 that is bent upward from the end of the second length portion 156.

여기서, 본 발명에 따른 리본와이어(130)가 제1리본와이어(140)와 제2리본와이어(150)를 포함하는 이유는 태양전지 어셈블리(100)의 상호 연결을 용이하게 하기 위한 것이다. The reason why the ribbon wire 130 according to the present invention includes the first ribbon wire 140 and the second ribbon wire 150 is to facilitate interconnection of the solar cell assembly 100.

일반적으로 본 발명에 따른 고집광형 태양전지모듈(10)은 어셈블리(100)가 제조되는 장소와 모듈(10)이 조립되는 장소는 서로 상이하기 때문에 다수의 어셈블리(100)는 별도로 제작된 후 모듈(10)을 조립하기 위한 장소로 이송되어 베이스플레이트(30)에 결합하게 된다. In general, since the high-concentration solar cell module 10 according to the present invention is different from the place where the assembly 100 is manufactured and the place where the module 10 is assembled, the plurality of assemblies 100 are manufactured separately and then the module ( 10) is transported to a place for assembling to be coupled to the base plate (30).

이때 어셈블리(100)는 이송의 편의성을 위하여 양측 단부에 구비되는 리본와이어(130) 즉, 제2리본와이어(150)는 제1리본와이어(140)가 완전한 하나의 리본와이어(130)로 이루어지는 것과는 달리 소정부위가 끊어진 상태로 어셈블리(100)에 조립된다. 그리고 이와 같이 조립된 다수의 어셈블리(100)의 연결은 모듈(10) 조립시 베이스플레이트(30)에 결합한 상태에서 제2리본와이어(150)를 서로 연결시킴으로써 이루어질 수 있다.At this time, the assembly 100 is a ribbon wire 130 provided at both ends for convenience of transfer, that is, the second ribbon wire 150 is that the first ribbon wire 140 is made of a complete ribbon wire 130 and Otherwise assembled to the assembly 100 in a predetermined state is broken. The connection of the plurality of assemblies 100 assembled as described above may be performed by connecting the second ribbon wires 150 to each other while being coupled to the base plate 30 when the module 10 is assembled.

이 경우, 본 발명에 따른 리본와이어(130)는 소정의 폭을 가지는 평평한 플레이트 형태로 이루어지기 때문에 소정부위가 끊어진 상태로 어셈블리(100)에 조립된 제2리본와이어(150)를 서로 연결하기는 용이하지 않다. In this case, since the ribbon wire 130 according to the present invention is formed in the form of a flat plate having a predetermined width, the second ribbon wire 150 assembled to the assembly 100 in a state where a predetermined portion is broken is not connected to each other. Not easy

그러나, 상술한 바와 같이, 제2리본와이어(150)가 제2길이부(152)의 단부에 상방으로 절곡된 절곡부(158)를 포함하게 되면, 서로 인접한 어셈블리(100)에 조립된 제2리본와이어(150)의 절곡부(158)를 서로 면 접촉시킨 후 용접, 리벳팅, 전도성 재료를 이용한 접합 등의 방법으로 쉽게 연결할 수 있기 때문에, 모듈(10)의 전체적인 조립성을 매우 향상시킬 수 있다.However, as described above, when the second ribbon wire 150 includes the bent portion 158 bent upward at the end of the second length portion 152, the second ribbon wire 150 is assembled to the adjacent assembly 100. Since the bent portions 158 of the ribbon wire 150 are brought into surface contact with each other and can be easily connected by welding, riveting, or bonding using a conductive material, the overall assembly of the module 10 can be greatly improved. have.

도면에는 어셈블리(100)에 두개의 태양전지(102)가 구비된 것이 도시되지만, 본 발명은 그에 한정하지 않으며, 하나의 어셈블리(100)에는 하나 또는 3개 이상의 태양전지(102)가 구비될 수 있으며, 하나의 어셈블리(100)에 구비되는 리본와이어(130)의 구성은 하나의 어셈블리(100)에 구비되는 태양전지(102)의 개수에 따라 달라질 수 있다. 예를 들어, 어셈블리(100)에 하나의 태양전지(102)가 구비되는 경우에는 제1리본와이어(140) 없이 2개의 제2리본와이어(150)만이 어셈블리(100)에 구비되며, 어셈블리(100)에 복수개의 태양전지(102)가 구비되는 경우에는 2개의 제2리본와이어(150)와 적어도 하나 이상의 제1리본와이어(140)가 어셈블리(100)에 구비될 수 있다.Although the drawings show that two solar cells 102 are provided in the assembly 100, the present invention is not limited thereto, and one assembly 100 may include one or three or more solar cells 102. The configuration of the ribbon wire 130 provided in one assembly 100 may vary depending on the number of solar cells 102 provided in one assembly 100. For example, when one solar cell 102 is provided in the assembly 100, only two second ribbon wires 150 are provided in the assembly 100 without the first ribbon wire 140 and the assembly 100. In the case where a plurality of solar cells 102 are provided, two second ribbon wires 150 and at least one first ribbon wire 140 may be provided in the assembly 100.

한편, 본 발명에 따른 어셈블리(100)는 도 7에서 보이는 바와 같이, 가로방향(x)으로 배열되어 서로 평행하게 연결될 수도 있지만, 도 8에서 보이는 바와 같이, 가로방향(x)의 끝단에 구비되는 어셈블리(100)의 경우에는 인접하는 가로방향(x)의 끝단에 구비되는 어셈블리(100)와 수직하게 연결될 필요가 있다. Meanwhile, as shown in FIG. 7, the assembly 100 according to the present invention may be arranged in a horizontal direction (x) and connected in parallel to each other. However, as shown in FIG. 8, the assembly 100 is provided at an end of the horizontal direction (x). In the case of the assembly 100, it is necessary to be vertically connected to the assembly 100 provided at the end of the adjacent horizontal direction (x).

이 경우, 제2리본와이어(150)의 제2길이부(152)는 가로방향으로 소정의 길이를 갖는 가로방향길이부(153)와, 가로방향길이부(153)로부터 수직 연결되어 세로방향(y)으로 소정의 길이를 갖는 세로방향길이부(155)로 이루어질 수 있다. In this case, the second length part 152 of the second ribbon wire 150 is vertically connected from the horizontal length part 153 and the horizontal length part 153 having a predetermined length in the horizontal direction, and thus the vertical length ( y) it may be made of a longitudinal length portion 155 having a predetermined length.

도 9는 회로기판의 개략적인 평면도이다.9 is a schematic plan view of a circuit board.

도 9를 참조하면, 태양전지(102)는 회로기판(104)의 대략 중심부에 장착되고, 회로기판(104)의 표면에는 태양전지(102)를 기준으로 양측으로 서로 전기적으로 연결되지 않는 2개의 전기전도성 연결부(105,106)가 형성될 수 있으며, 2개의 전기전도성 연결부(105,106) 중 어느 하나(105)는 태양전지(102)에 직접 연결되고, 다른 하나(106)는 리드선(108)에 의해 태양전지(102)에 연결될 수 있으며, 2개의 전기전도성 연결부(105,106) 사이에는 바이패스다이오드(by-pass diode)(107)가 구비될 수 있으며, 2개의 전기전도성 연결부(105,106)에는 리본와이어(130)의 플랜지부(146,156)가 납땜(soldering), 용접(welding) 등의 방법으로 부착결합됨에 따라 연결될 수 있다. 따라서 서로 소정간격으로 이격된 복수의 태양전지(102)는 리본와이어(130)에 의해 서로 통전될 수 있게 된다. Referring to FIG. 9, the solar cell 102 is mounted at an approximately center portion of the circuit board 104, and two surfaces of the circuit board 104 are not electrically connected to each other on both sides of the solar cell 102. Electroconductive connections 105, 106 may be formed, either one of the two electrically conductive connections 105, 106 being directly connected to the solar cell 102, and the other 106 being connected to the sun by a lead wire 108. It may be connected to the battery 102, the by-pass diode (107) may be provided between the two electrically conductive connectors 105, 106, the two electrically conductive connectors 105, 106, the ribbon wire 130 The flange portions 146 and 156 of the s) may be connected as they are attached to each other by soldering, welding, or the like. Therefore, the plurality of solar cells 102 spaced apart from each other at predetermined intervals may be energized with each other by the ribbon wire 130.

한편, 본 발명에 따른 리본와이어(130)는 얇은 플레이트 형태로 이루어지기 때문에 외부 충격에 의해 단차부(134)의 지지가 무너져 길이부(132)가 처질 염려가 있으며, 이 경우 처진 길이부(132)가 바닥면과 닿으면 단선 또는 합선 등의 문제를 야기하게 되므로, 리본와이어(130)의 처짐 방지 구조가 필요하다.On the other hand, since the ribbon wire 130 according to the present invention is formed in a thin plate shape, the support of the stepped portion 134 is collapsed due to an external impact, and thus the length portion 132 may sag. In this case, the sagging length portion 132 ) Causes a problem such as disconnection or short circuit when it comes into contact with the bottom surface, and thus a sag prevention structure of the ribbon wire 130 is required.

도 10은 본 발명의 다른 실시 예에 따른 리본와이어를 나타내는 사시도이다.10 is a perspective view showing a ribbon wire according to another embodiment of the present invention.

도 10을 참조하면, 본 실시 예에 따른 리본와이어(160)의 길이부(162)에는 양측면에서 하방으로 절곡되는 절곡부(165)가 구비될 수 있다. Referring to FIG. 10, the length portion 162 of the ribbon wire 160 according to the present embodiment may be provided with a bent portion 165 that is bent downward from both sides.

절곡부(165)는 길이부(162)의 양측면으로부터 연장형성될 수도 있지만, 상기 실시 예에 따른 평평한 형태의 길이부(162)의 양측면을 소정의 힘으로 눌러 절곡함에 의해 형성됨이 바람직하다. The bent portion 165 may be formed to extend from both sides of the length portion 162, but is preferably formed by pressing both sides of the length portion 162 of the flat form according to the embodiment by pressing a predetermined force.

이와 같이, 길이부(162)에 절곡부(165)가 형성되면, 리본와이어(160)가 외부 충격에 의해 그 구조가 무너지더라도 길이부(162)가 처지는 현상을 방지할 수 있다. As such, when the bent portion 165 is formed in the length portion 162, even if the structure of the ribbon wire 160 collapses due to external impact, the length portion 162 may be prevented from sagging.

본 발명에 따른 리본와이어(130,160)는 얇은 플레이트 형태로 이루어지기 때문에, 상기 실시 예에서와 같이 길이부(162)가 평평한 상태로만 이루어지게 되면, 외부 충격에 의해 단차부(164)가 무너지는 경우에 길이부(162)는 그대로 하방으로 처지게 된다.Since the ribbon wires 130 and 160 according to the present invention have a thin plate shape, when the length portion 162 is formed only in a flat state as in the above embodiment, the stepped portion 164 is collapsed by an external impact. The length portion 162 is sag downwards as it is.

그러나, 본 실시 예에 따른 리본와이어(160)와 같이, 길이부(162)에 절곡부(165)가 구비되면, 외부 충격에 의해 단차부(164)가 무너지더라도 길이부(162)는 하방으로 처지지 않게 된다. However, like the ribbon wire 160 according to the present embodiment, when the bent portion 165 is provided in the length portion 162, the length portion 162 is downward even if the stepped portion 164 collapses due to an external impact. Will not sag.

따라서, 본 실시 예에 따른 리본와이어(160)에 의하면, 외부 충격에 의해 길이부(162)가 처져 바닥면과 닿을 때 발생하는 단선 또는 합선 등의 문제를 방지할 수 있다. Therefore, according to the ribbon wire 160 according to the present embodiment, it is possible to prevent a problem such as disconnection or short circuit, which occurs when the length portion 162 sags due to external impact and contacts the bottom surface.

이상에서 살펴본 바와 같이, 본 발명은 상호 연결이 용이하며 처짐 방지 구조를 갖는 리본와이어를 구비하는 태양전지 어셈블리와, 이를 구비하는 고집광형 태양전지모듈에 관한 것으로서, 그 실시 형태는 다양한 형태로 변경가능하다 할 것이다. 따라서 본 발명은 본 명세서에서 개시된 실시 예에 의해 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 변경 가능한 모든 형태도 본 발명의 권리범위에 속한다 할 것이다.As described above, the present invention relates to a solar cell assembly having a ribbon wire that is easy to interconnect and has a sag-proof structure, and a highly condensed solar cell module having the same, the embodiment of which can be modified in various forms. Will do. Therefore, the present invention is not limited to the embodiments disclosed in the present specification, and all forms changeable by those skilled in the art to which the present invention pertains will belong to the scope of the present invention.
