Description

열전 발생기, 이의 제조 방법 및 이를 구비하는 열전 발생 장치. Thermoelectric generator, manufacturing method thereof, and thermoelectric generator comprising the same.
본 발명은 열전 발생기, 이의 제조 방법 및 이를 구비하는 열전 발생 장치에 관한 것이다.The present invention relates to a thermoelectric generator, a method of manufacturing the same, and a thermoelectric generator including the same.
열전소자는 양측면의 온도차로 인해 열에너지를 전기에너지로 변환하거나, 전기에너지를 열에너지로 변환하는 열전현상을 이용하는 소자이다. 이러한 열전소자를 활용하여 열을 전기로 변환시켜 전력을 회수하는 장치가 열전 발전기이다.A thermoelectric element is a device that uses the thermoelectric phenomenon to convert thermal energy into electrical energy or electrical energy into thermal energy due to a temperature difference between both sides. A thermoelectric generator is a device that uses these thermoelectric elements to convert heat into electricity and recover power.
이러한 열전 발전기는 내부에 고온의 배기가스와 열교환하는 고온부 열교환 핀, 열전 발전기 외부에 저온의 냉각수가 흐르는 저온부 열교환 핀으로 구성되어 있는데 열전 발전기의 효율을 높이기 위해서는 내부에 흐르는 배기가스의 높은 열에너지가 열전소자에 효율적으로 전달되어야 한다.This thermoelectric generator consists of a high-temperature heat exchange fin that exchanges heat with the high-temperature exhaust gas inside, and a low-temperature heat exchange fin through which low-temperature coolant flows outside the thermoelectric generator. In order to increase the efficiency of the thermoelectric generator, the high heat energy of the exhaust gas flowing inside is converted into thermoelectric energy. It must be efficiently delivered to the device.
하지만 종래의 사용하고 있는 고온부의 열교환 핀은 배기가스의 열에너지를 열전소자로 충분히 전달되지 않아 열전소자의 효율이 떨어져 전력을 회수하는 능력이 저하되는 문제점이 발생한다.However, the heat exchange fin of the high temperature part used in the related art does not sufficiently transfer the heat energy of the exhaust gas to the thermoelectric element, which causes a problem in that the efficiency of the thermoelectric element is reduced and the ability to recover power is reduced.
또한, 종래 고온부의 열교환 핀의 문제점은 내부에 들어오는 배기가스의 온도가 입구에서는 고온이고 출구쪽으로 이동하면서 열교환이 되기 때문에 배기가스의 온도가 감소하게 된다. 이에 따라 입구쪽의 배치된 열전소자는 온도차이가 커 효율이 증가하지만, 출구쪽에 배치된 열전소자는 온도차이가 작아 효율이 감소하여 전체적으로 열전소자 균일한 효율을 얻기 어렵다.In addition, the problem with the conventional high-temperature heat exchange fin is that the temperature of the exhaust gas entering the inside is high at the inlet and heat exchange occurs as it moves toward the outlet, so the temperature of the exhaust gas decreases. Accordingly, the efficiency of the thermoelectric element placed at the inlet increases due to the large temperature difference, but the efficiency of the thermoelectric element placed at the outlet decreases due to the small temperature difference, making it difficult to obtain uniform efficiency throughout the thermoelectric element.

또한, 본 발명에 따른 열전 발전기는 종래의 열전 발전기에 비해 열전 소자의 효율이 향상되어 폐열을 통해 더 많은 전력의 회수가 가능하다.In addition, the thermoelectric generator according to the present invention has improved thermoelectric element efficiency compared to the conventional thermoelectric generator, allowing more power to be recovered through waste heat.
또한, 본 발명에 따른 열전 발전기는 차량, 플랜트 등 다양한 열전 발전이 필요한 곳에 다양하게 적용 가능하다.In addition, the thermoelectric generator according to the present invention can be applied to various places where thermoelectric power generation is required, such as vehicles and plants.
또한, 종래의 열전 발전기 열 교환 핀은 고온의 공기가 가진 열 에너지를 열전 소자로 충분히 전달하지 않기 때문에, 상기 열 교환핀에 배치된 열전 소자의 효율이 떨어져 전력 회수의 능력이 저하된다. 그러나, 본 발명에 따른 열전 발전기는 고온의 공기가 공기 분배 핀으로 인해 각각의 공기 방열핀으로 분배되고, 열전 소자가 위치한 영역에서 충돌이 일어난 후, 공기 방열핀을 거쳐 공기 배출부를 통해 유출되는 유동구조를 가진다. 이러한 공기 유동구조에 의해 열전 소자에서 충돌 효과가 일어남으로써 열 에너지를 충분히 전달되지 않는 문제점을 보완할 수 있다. 이에 따라 전력 회수 능력이 증가하기 때문에 에너지 및 비용 절감의 효과를 얻을 수 있다.In addition, because the heat exchange fin of a conventional thermoelectric generator does not sufficiently transfer the heat energy of high-temperature air to the thermoelectric element, the efficiency of the thermoelectric element disposed on the heat exchange fin is reduced, thereby reducing the power recovery ability. However, the thermoelectric generator according to the present invention has a flow structure in which high-temperature air is distributed to each air heat dissipation fin due to the air distribution fin, and after a collision occurs in the area where the thermoelectric element is located, it flows out through the air discharge portion through the air heat dissipation fin. have Due to this air flow structure, a collision effect occurs in the thermoelectric element, thereby solving the problem of insufficient transfer of heat energy. As a result, power recovery ability increases, resulting in energy and cost savings.
다만, 본 발명에서 얻을 수 있는 효과는 상기된 바와 같은 효과들로 한정되지 않으며, 또 다른 효과들이 존재할 수 있다.However, the effects that can be obtained from the present invention are not limited to the effects described above, and other effects may exist.

본 발명에 따른 열전 발전기(10)는 방열핀(200) 및 공기 분배핀(100)이 결합되어 형성된 것으로서, 이하의 설명은 도 1 내지 도 13 을 참고할 수 있다.The thermoelectric generator 10 according to the present invention is formed by combining a heat dissipation fin 200 and an air distribution fin 100, and the following description may refer to FIGS. 1 to 13.
일반적으로 열전 소자는 양측면의 온도차를 통해 열 에너지를 전기 에너지로 변환하거나, 또는 전기 에너지를 열 에너지로 변환하는 열전 현상을 이용하는 소자이다. 이러한 열전소자를 활용하여 열을 전기로 변환시켜 전력을 회수하는 장치가 열전 발전기(10)이다. 이러한 열전 발전기(10)는 내부에 고온의 배기가스와 열교환하는 고온부 열교환 핀, 열전 발전기(10) 외부에 저온의 냉각수가 흐르는 저온부 열교환 핀 등을 포함하고, 열전 발전기(10)의 효율을 높이기 위해서는 내부에 흐르는 배기가스의 높은 열에너지가 열전소자에 효율적으로 전달되어야 한다. 그러나, 종래의 열전 발전기(10)에서 사용되고 있는 고온부의 열교환 핀은 배기가스의 열 에너지를 열전 소자로 충분히 전달하지 못하는 단점이 있다. 또한, 열 교환핀의 입구에 들어오는 공기는 이동과정에서 열 교환되오 배기가스의 온도가 감소하게 되어, 입구쪽의 배치된 열전 소자는 높은 온도 차이에 의해 효율이 증가하지만, 출구쪽에 배치된 열전 소자는 온도 차이가 작아 효율이 감소하는 문제가 존재한다.In general, a thermoelectric element is a device that converts thermal energy into electrical energy through a temperature difference between two sides, or uses a thermoelectric phenomenon that converts electrical energy into thermal energy. A thermoelectric generator 10 is a device that recovers power by converting heat into electricity using such thermoelectric elements. This thermoelectric generator 10 includes a high-temperature heat exchange fin that exchanges heat with the high-temperature exhaust gas inside, a low-temperature heat exchange fin through which low-temperature coolant flows outside the thermoelectric generator 10, etc. In order to increase the efficiency of the thermoelectric generator 10, The high thermal energy of the exhaust gas flowing inside must be efficiently transferred to the thermoelectric element. However, the heat exchange fin of the high temperature portion used in the conventional thermoelectric generator 10 has the disadvantage of not sufficiently transferring the heat energy of the exhaust gas to the thermoelectric element. In addition, the air entering the inlet of the heat exchange fin exchanges heat during the movement process, which reduces the temperature of the exhaust gas. The efficiency of the thermoelectric element placed at the inlet increases due to the high temperature difference, but the thermoelectric element placed at the outlet increases. There is a problem of reduced efficiency due to the small temperature difference.
이러한 문제를 해결하기 위해, 본 발명에 따른 열전 발전기(10)는 공기가 유입되는 유로와 배출되는 유로를 분리함으로써 입구 쪽의 열전 소자(230)와 출구 쪽의 열전 소자(230) 사이의 열전 발전 효율 차이를 낮출 수 있다.To solve this problem, the thermoelectric generator 10 according to the present invention generates thermoelectric power between the thermoelectric element 230 on the inlet side and the thermoelectric element 230 on the outlet side by separating the flow path through which air flows in and the air discharge path. The efficiency gap can be reduced.

Referring to Figure 1, it can be seen that a hexagonal empty space surrounded by the air distribution pin 100 is located. Since thermoelectric generators are generally applied to vehicles and plants, the empty space is a space where the shaft is connected to fix the thermoelectric generator, and serves as a distribution guide for high temperature exhaust gas to move from the inlet to the thermoelectric generator (10). It is a space to practice.
본 발명의 일 구현예에 따르면, 공기 유로(300)는, 열전 발전기(10)의 외부로부터 공기가 유입되는 공기 유입 유로(310), 열전 발전기(10)의 내부로부터 공기가 배출되는 공기 배출 유로(330), 및 공기 유입 유로(310)와 공기 배출 유로(330)를 연결하는 공기 분배 유로(320)를 포함할 수 있으나, 이에 제한되는 것은 아니다.According to one embodiment of the present invention, the air flow path 300 includes an air inlet flow path 310 through which air flows in from the outside of the thermoelectric generator 10, and an air discharge path through which air is discharged from the inside of the thermoelectric generator 10.

It may be discharged to the discharge area formed by the other side 132 and the air distribution unit 101, but is not limited thereto.
도 10 및 도 11 을 참조하면, 공기 유입 유로(310)는 공기 유입부(120)의 일면(121), 유로 분리판(111), 및 공기 배출부(130)의 일면(131)에 의해 형성된 유로이고, 공기 배출 유로(330)는 공기 배출부(130)의 타면(132), 유로 분리판(111), 및 공기 유입부(120)의 타면(122)에 의해 형성된 유로를 의미한다. 이와 관련하여, 열전 발전기(10)에 유입되는 공기의 흐름이 7시 방향에서 1시 방향으로 향할 때, 공기 유입부(120)의 일면(121)을 통해 유입되는 공기는 공기 배출부(130)의 일면(131)에 의해 배출되지 않고, 공기 유입부(120)의 타면(122)에 의해 공기의 유입이 차단되어 있어 공기 배출부(130)는 공기를 배출할 수 없는 문제가 있다. 10 and 11, the air inlet flow path 310 is formed by one side 121 of the air inlet 120, the flow path separator 111, and one side 131 of the air outlet 130. It is a flow path, and the air discharge flow path 330 refers to a flow path formed by the other surface 132 of the air discharge unit 130, the flow path separator plate 111, and the other surface 122 of the air inlet 120. In this regard, when the flow of air flowing into the thermoelectric generator 10 is directed from the 7 o'clock direction to the 1 o'clock direction, the air flowing in through one side 121 of the air inlet 120 is directed to the air outlet 130. There is a problem in that air cannot be discharged from the air outlet 130 because the air is not discharged by one side 131 and the inflow of air is blocked by the other side 122 of the air inlet 120.
본 발명에 따른 열전 발전기(10)는, 공기 유입 유로(310)와 공기 배출 유로(330) 사이에 형성되고, 유로 분리판(111)과 방열 분배핀(220)이 접촉하여 형성된 공기 분배 유로(320)를 포함할 수 있으며, 공기 분배 유로(320)는 방열 분배핀(220) 사이의 영역을 의미한다. 즉, 공기 유입 유로(310)에 유입된 공기는, 공기 분배 유로(320)를 거쳐 공기 배출 유로(330)로 이동할 수 있다.The thermoelectric generator 10 according to the present invention is formed between the air inlet flow path 310 and the air discharge flow path 330, and the air distribution path formed by contact between the flow path separator plate 111 and the heat dissipation distribution pin 220 ( 320), and the air distribution passage 320 refers to an area between the heat dissipation distribution fins 220. That is, the air flowing into the air inflow passage 310 may move to the air discharge passage 330 through the air distribution passage 320.
본 발명의 일 구현예에 따르면, 공기 유입부(120)에 유입된 공기가 공기 유로(300)를 통과하는 과정에서, 열전 소자(230)는 공기에 의해 가열되어 발전할 수 있으나, 이에 제한되는 것은 아니다.According to one embodiment of the present invention, while the air introduced into the air inlet 120 passes through the air flow path 300, the thermoelectric element 230 may be heated by the air and generate power, but is limited thereto. That is not the case.
공기 유입부(120)의 일면(121)을 통해 유입된 고온의 공기는, 공기 분배 유로(320)를 통과하는 과정에서 방열핀(200)의 방열 기판(210)과 충돌 또는 접촉할 수 있다. 이 때 방열 기판(210)의 타측면 상에는 열전 소자(230)가 존재하기 때문에, 고온의 공기가 이동하는 과정에서 방열 기판(210)을 가열시키고, 가열된 방열 기판(210)은 열전 소자(230)가 발전할 수 있는 열원을 제공할 수 있다.High-temperature air introduced through one surface 121 of the air inlet 120 may collide with or contact the heat dissipation substrate 210 of the heat dissipation fin 200 while passing through the air distribution passage 320. At this time, since the thermoelectric element 230 is present on the other side of the heat dissipation substrate 210, the heat dissipation substrate 210 is heated in the process of moving the high temperature air, and the heated heat dissipation substrate 210 is connected to the thermoelectric element 230. ) can provide a heat source for power generation.
본 발명의 일 구현예에 따르면, 방열 분배핀(220) 및 공기 분배부(101)가 이루는 각도는 70° 내지 110° 일 수 있으나, 이에 제한되는 것은 아니다.According to one embodiment of the present invention, the angle formed by the heat dissipation distribution fin 220 and the air distribution part 101 may be 70° to 110°, but is not limited thereto.
앞서 언급하였듯 방열 분배핀(220)과 공기 분배부(101)는 서로 접촉하여 공기 분배 유로(320)를 형성해야 한다. 이 때, 방열 분배핀(220)과 공기 분배부(101), 구체적으로 방열 분배핀(220)과 유로 분리판(111)이 서로 평행할 경우 공기 분배 유로(320)의 형성이 이루어지지 않기 때문에, 방열 분배핀(220)과 공기 분배부(101)가 이루는 각도는 70° 내지 110° 일 수 있다. 다만, 방열 분배핀(220)과 공기 분배부(101) 사이의 각도는, 공기 분배 유로(320)가 형성될 수 있도록 엇갈리기만 하면 되는 것으로서, 공기 분배 유로(320)가 형성되지 않을 경우 유입된 공기가 배출되지 못하는 문제가 발생한다.As mentioned earlier, the heat dissipation distribution pin 220 and the air distribution part 101 must contact each other to form an air distribution passage 320. At this time, when the heat dissipation distribution fin 220 and the air distribution unit 101, specifically the heat dissipation distribution fin 220 and the flow path separator plate 111, are parallel to each other, the air distribution flow path 320 is not formed. , the angle formed by the heat dissipation distribution fin 220 and the air distribution unit 101 may be 70° to 110°. However, the angle between the heat dissipation distribution pin 220 and the air distribution unit 101 need only be staggered so that the air distribution passage 320 can be formed, and if the air distribution passage 320 is not formed, the inflow A problem occurs in which the contaminated air cannot be discharged.
