Description

Technical Field

[0001] The present invention relates to a thermoelectric module and a power generation device including the thermoelectric module, and more specifically, to a thermoelectric module utilizing the temperature difference between a low-temperature part and a high-temperature part of a thermoelectric element and a power generation device including the thermoelectric module or a Peltier device for cooling or heating a specific object (such as a fluid). Background Technology

[0002] Thermoelectric phenomena are caused by the movement of electrons and holes within a material, and refer to the direct energy conversion between thermal energy and electrical energy.

[0003] Thermoelectric element is a general term for a component that utilizes the thermoelectric phenomenon. Its structure consists of a PN junction pair formed by bonding P-type thermoelectric material and N-type thermoelectric material between metal electrodes.

[0004] Thermoelectric elements can be classified into elements that utilize the change of resistance with temperature, elements that utilize the Seebeck effect (i.e., the phenomenon of electromotive force generated by temperature difference), and elements that utilize the Peltier effect (i.e., the phenomenon of heat absorption or heating generated by electric current).

[0005] Thermoelectric elements are widely used in household appliances, electronic components, and communication devices. For example, thermoelectric elements can be used in cooling devices, heating devices, and power generation devices. Therefore, the demand for the thermoelectric performance of thermoelectric elements is gradually increasing.

[0006] Recently, there has been a need to generate electricity using the high-temperature waste heat produced by engines and thermoelectric elements in vehicles, ships, and other applications. In this case, a fluid flow part through which a first fluid passes is located on the low-temperature section of the thermoelectric element, while a heat sink is located on the high-temperature section of the thermoelectric element, and a second fluid can pass through the heat sink. Therefore, electricity can be generated by utilizing the temperature difference between the low-temperature and high-temperature sections of the thermoelectric element. Summary of the Invention

[0080] Figure 1 This is a perspective view of a power generation device according to an embodiment of the present invention. Figure 2 This is an exploded perspective view of a power generation device according to an embodiment of the present invention.

[0081] refer to Figure 1 and Figure 2 The power generation device 1000 includes a fluid inlet 1100 and a thermoelectric module 1200 disposed on the surface of the fluid inlet 1100. Multiple power generation devices 1000 can be arranged in parallel to each other at predetermined intervals to form a power generation system.

[0082] According to an embodiment of the present invention, the power generation device 1000 can generate electricity by utilizing the temperature difference between a first fluid flowing through the interior of the fluid inlet 1100 and a second fluid flowing through the exterior of the fluid inlet 1100.

[0083] The first fluid introduced into the fluid inlet 1100 can be water, but is not limited thereto, and can be various types of fluids with cooling properties. The temperature of the first fluid introduced into the fluid inlet 1100 can be below 100°C, preferably below 50°C, more preferably below 40°C, but is not limited thereto, and can be a fluid with a lower temperature than the second fluid. The temperature of the first fluid discharged after passing through the fluid inlet 1100 can be higher than the temperature of the first fluid introduced into the fluid inlet 1100.

[0084] A first fluid is introduced into the fluid inlet of the fluid inlet portion 1100 and discharged through the fluid outlet. To facilitate the introduction and discharge of the first fluid and to support the fluid inlet portion 1100, an inlet flange (not shown) and an outlet flange (not shown) may also be provided on the fluid inlet and fluid outlet of the fluid inlet portion 1100, respectively. Optionally, a plurality of fluid inlets (not shown) may be formed on a first surface 1110, a second surface 1120 opposite to the first surface 1110, and a fifth surface 1150 configured to be perpendicular to a third surface 1130 between the first surface 1110 and the second surface 1120 of the fluid inlet portion 1100, and a plurality of fluid outlets 1162 may be formed on a sixth surface 1160 opposite to the fifth surface 1150. The plurality of fluid inlets (not shown) and the plurality of fluid outlets 1162 may be connected to a plurality of fluid channel pipes (not shown) in the fluid inlet portion 1100. Therefore, the first fluid introduced into each fluid inlet can be discharged from each fluid outlet 1162 after passing through each fluid channel pipe.

[0085] However, this is illustrative, and the number, location, shape, etc., of the fluid inlets and outlets are not limited thereto. A fluid inlet, a fluid outlet, and a fluid passage connecting the fluid inlet and the fluid outlet may also be formed in the fluid inlet section 1100.

[0086] Simultaneously, the second fluid flows through the outside of the fluid inlet 1100, for example, through the radiator 1220 of the thermoelectric module 1200 located outside the fluid inlet 1100. The second fluid may refer to waste heat generated from engines such as those in automobiles and ships, but is not limited thereto. For example, the temperature of the second fluid may be 100°C or higher, preferably 200°C or higher, more preferably 220°C to 250°C, but is not limited thereto, and may be a fluid with a higher temperature than the first fluid.

[0087] In this specification, an example will be described where the temperature of the first fluid flowing through the interior of the fluid inlet 1100 is lower than the temperature of the second fluid flowing through the radiator 1220 of the thermoelectric module 1200 located outside the fluid inlet 1100. Therefore, in this specification, the fluid inlet 1100 may be referred to as a conduit or a cooling section. However, embodiments of the present invention are not limited thereto, and the temperature of the first fluid flowing through the interior of the fluid inlet 1100 may also be higher than the temperature of the second fluid flowing through the radiator 1220 of the thermoelectric module 1200 located outside the fluid inlet 1100.

[0088] According to an embodiment of the present invention, the thermoelectric module 1200 includes a thermoelectric element 1210 and a heat sink 1220 disposed on the thermoelectric element 1210. The thermoelectric element 1210 according to an embodiment of the present invention may have... Figure 3 and Figure 4 The structure of the thermoelectric element 100 shown.

[0089] refer to Figure 3 and Figure 4 The thermoelectric element 100 includes a first panel 110, a first electrode 120, a P-type thermoelectric leg 130, an N-type thermoelectric leg 140, a second electrode 150, and a second panel 160.

[0090] The first electrode 120 is disposed between the first panel 110 and the lower bottom surfaces of the P-type thermoelectric legs 130 and N-type thermoelectric legs 140, and the second electrode 150 is disposed between the second panel 160 and the upper bottom surfaces of the P-type thermoelectric legs 130 and N-type thermoelectric legs 140. Therefore, multiple P-type thermoelectric legs 130 and multiple N-type thermoelectric legs 140 are electrically connected through the first electrode 120 and the second electrode 150. A pair of P-type thermoelectric legs 130 and N-type thermoelectric legs 140 disposed between the first electrode 120 and the second electrode 150 and electrically connected can form a unit cell.

[0091] For example, when a voltage is applied to the first electrode 120 and the second electrode 150 via wires 181 and 182, due to the Peltier effect, the panel of the current flowing from the P-type thermocouple 130 to the N-type thermocouple 140 can absorb heat and act as a cooling element, while the panel of the current flowing from the N-type thermocouple 140 to the P-type thermocouple 130 can be heated and act as a heating element. Optionally, when a temperature difference is applied between the first electrode 120 and the second electrode 150, the charges in the P-type thermocouple 130 and the N-type thermocouple 140 can move due to the Seebeck effect, and electricity can be generated.

[0092] Here, the P-type thermoelectric leg 130 and the N-type thermoelectric leg 140 can be bismuth telluride (Bi-Te) based thermoelectric legs containing bismuth (Bi) and tellurium (Te) as main materials. The P-type thermoelectric leg 130 can be a bismuth telluride (Bi-Te) based thermoelectric leg containing at least one of antimony (Sb), nickel (Ni), aluminum (Al), copper (Cu), silver (Ag), lead (Pb), boron (B), gallium (Ga), tellurium (Te), bismuth (Bi), and indium (In). For example, the P-type thermoelectric leg 130 can contain 99% to 99.999% by weight of Bi-Sb-Te, with Bi-Sb-Te as the main raw material, and based on 100% by weight, it contains 0.001% to 1% by weight of at least one of nickel (Ni), aluminum (Al), copper (Cu), silver (Ag), lead (Pb), boron (B), gallium (Ga), and indium (In). The N-type thermoelectric leg 140 may be a bismuth telluride (Bi-Te) based thermoelectric leg, comprising at least one of selenium (Se), nickel (Ni), aluminum (Al), copper (Cu), silver (Ag), lead (Pb), boron (B), gallium (Ga), tellurium (Te), bismuth (Bi), and indium (In). For example, the N-type thermoelectric leg 140 may comprise 99% to 99.999% by weight of Bi-Se-Te, with Bi-Se-Te as the main raw material, and based on 100% by weight, it may comprise 0.001% to 1% by weight of at least one of nickel (Ni), aluminum (Al), copper (Cu), silver (Ag), lead (Pb), boron (B), gallium (Ga), and indium (In).

[0093] P-type thermoelectric legs 130 and N-type thermoelectric legs 140 can be formed in bulk or stacked form. Generally, bulk P-type thermoelectric legs 130 or bulk N-type thermoelectric legs 140 can be obtained by: manufacturing ingots by heat-treating thermoelectric materials, obtaining powder for the thermoelectric legs by grinding and sieving the ingots, then sintering the powder for the thermoelectric legs, and cutting the sintered body. In this case, P-type thermoelectric legs 130 and N-type thermoelectric legs 140 can be polycrystalline thermoelectric legs. As mentioned above, when P-type thermoelectric legs 130 and N-type thermoelectric legs 140 are polycrystalline thermoelectric legs, their strength can be increased. Stacked P-type thermoelectric legs 130 or stacked N-type thermoelectric legs 140 can be obtained by applying a paste including thermoelectric materials onto a sheet panel to form a unit component, then stacking and cutting the unit component.

[0094] In this case, a pair of P-type thermoelectric legs 130 and N-type thermoelectric legs 140 can have the same shape and volume or different shapes and volumes. For example, due to the different electrical conductivity characteristics of the P-type thermoelectric legs 130 and N-type thermoelectric legs 140, the height or cross-sectional area of ​​the N-type thermoelectric leg 140 can also be formed to be different from the height or cross-sectional area of ​​the P-type thermoelectric leg 130.

[0095] In this case, the P-type thermoelectric leg 130 or the N-type thermoelectric leg 140 can be cylindrical, polygonal, elliptical, etc.

[0096] In the instruction manual, the thermoelectric leg can also be referred to as a thermoelectric structure, semiconductor device, semiconductor structure, etc.

[0097] According to an embodiment of the present invention, the performance of a thermoelectric element can be represented by a quality factor (ZT). The quality factor (ZT) can be represented as shown in Equation 1.

[0098] [Equation 1]

[0099] ZT=α 2 ·σ·T / k

[0100] Here, α refers to the Seebeck coefficient [V / K], σ refers to the conductivity [S / m], and α 2 σ refers to the power factor [W / mK] 2 Furthermore, T refers to temperature, and k refers to thermal conductivity [W / mK]. k can be expressed as a·cp·ρ, where a refers to thermal diffusivity [cm]. 2 / S], cp refers to specific heat [J / gK], ρ refers to density [g / cm³] 3 ].

[0101] To obtain the quality factor of a thermoelectric element, the Z-value (V / K) can be measured using a Z-meter, and the quality factor (ZT) can be calculated using the measured Z-value.

[0102] Here, the first electrode 120 disposed between the first panel 110 and the P-type thermocouple 130 and the N-type thermocouple 140, and the second electrode 150 disposed between the second panel 160 and the P-type thermocouple 130 and the N-type thermocouple 140, may contain at least one of copper (Cu), silver (Ag), and aluminum (Al), and have a thickness in the range of 0.01 mm to 0.3 mm. When the first electrode 120 or the second electrode 150 has a thickness of less than 0.01 mm, the functionality of the electrode is reduced, thereby reducing the conductivity. Furthermore, when the thickness exceeds 0.3 mm, the conductivity decreases due to the increase in resistance.

[0103] Furthermore, the first panel 110 and the second panel 160, which are opposite each other, can be metal plates with a thickness ranging from 0.1 mm to 1.5 mm. When the thickness of the metal plate is less than 0.1 mm or greater than 1.5 mm, the heat dissipation characteristics or thermal conductivity will increase excessively, thereby reducing the reliability of the thermoelectric element. Additionally, when the first panel 110 and the second panel 160 are metal plates, an insulating layer 170 may be formed between the first panel 110 and the first electrode 120, and between the second panel 160 and the second electrode 150. The insulating layer 170 may comprise a material having a thermal conductivity of 1 W / mK to 20 W / mK. In this case, the insulating layer 170 may be a layer composed of a resin composition comprising at least one of epoxy resin and silicone resin and an inorganic material, or a layer composed of a silicone resin composition comprising silicone resin and an inorganic material, or an alumina layer. Here, the inorganic material may be at least one of oxides, nitrides, and carbides of aluminum, boron, silicon, etc.

[0104] In this configuration, the first panel 110 and the second panel 160 can be formed with different dimensions. In other words, the volume, thickness, or area of ​​one of the first panel 110 and the second panel 160 can be greater than the volume, thickness, or area of ​​the other. Here, the thickness can be the thickness from the first panel 110 toward the second panel 160, and the area can be the area in a direction perpendicular to the direction from the first panel 110 toward the second panel 160. Therefore, the heat absorption or heat dissipation performance of the thermoelectric element can be enhanced. Preferably, the volume, thickness, or area of ​​the first panel 110 can be formed to be greater than at least one of the volume, thickness, and area of ​​the second panel 160. In this case, when the first panel 110 is disposed in a high-temperature region for the Seebeck effect, when the first panel 110 is used as a heating region for the Peltier effect, or when a sealing member (described below) for protecting the thermoelectric element from external environmental influences is disposed on the first panel 110, the first panel 110 can be formed to be greater than at least one of the volume, thickness, and area of ​​the second panel 160. In this case, the area of ​​the first panel 110 can be formed in the range of 1.2 to 5 times the area of ​​the second panel 160. When the area of ​​the first panel 110 is less than 1.2 times the area of ​​the second panel 160, the effect on improving heat transfer efficiency is not significant, while when the area of ​​the first panel 110 exceeds 5 times, the heat transfer efficiency is significantly reduced, and it may be difficult to maintain the basic shape of the thermoelectric module.

[0105] Furthermore, a heat dissipation pattern, such as an embossed pattern, may be formed on the surface of at least one of the first panel 110 and the second panel 160. This enhances the heat dissipation performance of the thermoelectric element. When the embossed pattern is formed on the surface in contact with the P-type thermoelectric leg 130 or the N-type thermoelectric leg 140, the bonding characteristics between the thermoelectric leg and the plate can also be improved.

[0106] Although not shown, a sealing member may also be provided between the first panel 110 and the second panel 160. The sealing member may be provided on the side surfaces of the first electrode 120, the P-type thermoelectric leg 130, the N-type thermoelectric leg 140, and the second electrode 150 between the first panel 110 and the second panel 160. Therefore, the first electrode 120, the P-type thermoelectric leg 130, the N-type thermoelectric leg 140, and the second electrode 150 can be sealed and isolated from external moisture, heat, contaminants, etc.

[0107] Refer again Figure 1 and Figure 2 According to an embodiment of the present invention, the thermoelectric module 1200 includes a thermoelectric element 1210 and a heat sink 1220 disposed on the thermoelectric element 1210. Figure 1 and Figure 2 Two thermoelectric modules 1200-1 and 1200-2 are shown to be disposed on the first surface 1110 of the fluid inlet 1100, and two thermoelectric modules 1200-3 and 1200-4 are also disposed on the second surface 1120. However, the invention is not limited thereto, and two or more thermoelectric modules may be disposed on one surface.

[0108] As described above, each thermoelectric element 1210 includes a first panel 110 configured to contact the fluid inflow portion 1100, a plurality of first electrodes 120 disposed on the first panel 110, a plurality of thermoelectric legs 130 and 140 disposed on the plurality of first electrodes 120, a plurality of second electrodes 150 disposed on the plurality of thermoelectric legs 130 and 140, a second panel 160 disposed on the plurality of second electrodes 150, and a heat sink disposed on the second panel 160. Furthermore, an insulating layer 170 may also be disposed between the first panel 110 and the plurality of first electrodes 120, and between the plurality of second electrodes 150 and the second panel 160.

[0109] In this configuration, the first panel of the thermoelectric element 1210 disposed on the fluid inlet 1100 can be a metal plate, which can be bonded to the surface of the fluid inlet 1100 via a thermal interface material (TIM) (not shown). Due to the excellent heat transfer properties of the metal plate, heat transfer between the thermoelectric element and the fluid inlet 1100 is facilitated. Furthermore, when the metal plate and the fluid inlet 1100 are bonded via the TIM, heat transfer between them is not interfered with. Here, the metal plate can be one of a copper plate, an aluminum plate, or a copper-aluminum plate, but the invention is not limited thereto.

[0110] As described above, according to an embodiment of the invention, a plurality of thermoelectric modules 1200 are disposed on the surface of the fluid inlet 1100. Each of the plurality of thermoelectric modules 1200 may include a connector for power supply, to extract the generated electricity to the outside, or to use the generated electricity as a Peltier device. According to an embodiment of the invention, a cover member 1400 may be disposed on the connector to uniformly maintain the engagement force between the thermoelectric module 1200 and the fluid inlet 1100 and to protect the conductive wires connected to the connector.

[0112] refer to Figures 5 to 12The thermoelectric module 1200 is disposed on the first surface 1110 of the fluid inlet 1100. For ease of description, only the thermoelectric module 1200 disposed on the first surface 1110 of the fluid inlet 1100 will be described below; however, the invention is not limited thereto, and the same structure can also be applied to the second surface 1120, which is the surface opposite to the first surface 1110. Details regarding the fluid inlet 1100 and the thermoelectric module 1200 will be omitted from the references. Figures 1 to 4 Repeated descriptions of content that are identical.

[0113] According to an embodiment of the present invention, a first panel 1212 of the thermoelectric module 1200 is disposed on a first surface 1110 of the fluid inlet 1100. In this case, the first panel 1212 may be configured to directly contact the first surface 1110 of the fluid inlet 1100, or to indirectly contact the first surface 1110 via a TIM or the like. The first panel 1212 may be a reference... Figures 1 to 4 The first panel 110 is described. Therefore, regarding the first panel 1212, references will be omitted. Figures 1 to 4 The description of the first panel 110 is a repetition of the same content.

[0114] like Figure 6 and Figure 7 As shown, the first panel 1212 of the thermoelectric module 1200 may include a first region A1 and a second region A2. In this case, a plurality of first electrodes, a plurality of thermoelectric legs, a plurality of second electrodes, a second panel, and a heat sink 1220 are disposed in the first region A1, and connector components 210 and 220 connected to the first electrodes may be disposed in the second region A2, which is one side of the first region A1. Here, the plurality of first electrodes, the plurality of thermoelectric legs, the plurality of second electrodes, and the second panel may be referenced. Figures 1 to 4 The description includes a plurality of first electrodes 120, a plurality of thermoelectric legs 130 and 140, a plurality of second electrodes 150, and a second panel 160.

[0115] According to an embodiment of the present invention, the fluid inlet 1100 and the thermoelectric module 1200 can be connected by a connecting member 1300. For this purpose, a plurality of 1-1 through holes S11 can be formed in the first surface 1110 of the fluid inlet 1100, and a plurality of 1-2 through holes S12 corresponding to the plurality of 1-1 through holes S11 can also be formed in the first region A1 of the first panel 1212 of the thermoelectric module 1200. Furthermore, a plurality of 1-3 through holes S13 corresponding to the plurality of 1-1 through holes S11 and the plurality of 1-2 through holes S12 can also be formed in the second panel (not shown) and the heat sink 1220 of the thermoelectric module 1200. Therefore, as... Figures 8 to 11As shown, multiple first connecting members 1310 can be connected to multiple 1-1 through holes S11, multiple 1-2 through holes S12 and multiple 1-3 through holes S13, so that the fluid inflow section 1100 and the thermoelectric module 1200 can be connected.

[0116] Furthermore, according to an embodiment of the present invention, a plurality of 2-1 through holes S21 may be formed in the first surface 1110 of the fluid inflow portion 1100, and a plurality of 2-2 through holes S22 corresponding to the plurality of 2-1 through holes S21 may be formed in the second region A2 of the first panel 1212 of the thermoelectric module 1200. In addition, a cover member 1400 may be provided in the second region A2 of the first panel 1212, and as... Figure 12 As shown, a plurality of 2-3 through holes S23 corresponding to a plurality of 2-1 through holes S21 and a plurality of 2-2 through holes S22 can be formed in the cover member 1400. A plurality of second connecting members 1320 can be connected to the plurality of 2-1 through holes S21, the plurality of 2-2 through holes S22 and the plurality of 2-3 through holes S23, so that the fluid inlet 1100, the thermoelectric module 1200 and the cover member 1400 can be connected.

[0117] Therefore, since the first region A1 and the second region A2 of the first panel 1212 of the thermoelectric module 1200 can also be adjacent to the fluid inflow portion 1100, the entire first panel 1212 of the thermoelectric module 1200 can have a uniform bonding force with the fluid inflow portion 1100, and the heat can be evenly distributed on the entire first panel 1212.

[0118] In particular, such as Figure 11 As shown, when the first panel 1212 of the thermoelectric module 1200 and the fluid inlet 1100 are connected using the cover member 1400, the connection torque of the second connecting member 1320 can be increased by applying the cover member 1400. Therefore, since the second connecting member 1320 is unlikely to be released even under vibration conditions, the thermoelectric module 1200 can be more securely attached to the fluid inlet 1100.

[0119] In this case, the width D of the cover member 1400 can be substantially the same as the width D' of the first panel 1212 on which the cover member 1400 is disposed. For example, the width D of the cover member 1400 can be 0.9 to 1 times, preferably 0.925 to 1 times, and more preferably 0.95 to 1 times, of the width D' of the first panel 1212 on which the cover member 1400 is disposed. Therefore, the cover member 1400 can press down the entire width D' of the first panel 1212, thereby preventing the first panel 1212 from deforming or separating.

[0120] More specifically, multiple 2-3 through holes S23 can be formed on both sides of the cover member 1400 to uniformly support both sides of the second region A2 of the first panel 1212 in a balanced manner and prevent thermal deformation of the first panel 1212. In this case, the distance d3 between two 2-3 through holes S23 in a cover member 1400 can be greater than the distance d4 between two 1-3 through holes S13 in a heat sink 1220. Therefore, the cover member 1400 can uniformly support both sides of the second region A2 of the first panel 1212 in a balanced manner.

[0121] At the same time, such as Figure 12 As shown, the plurality of 2-3 through holes S23 formed on both sides of the cover member 1400 can be in the shape of having stepped inner walls. In other words, the diameter d1 of the 2-3 through holes S23 in the first surface 1402 facing the first panel 1212 of the cover member 1400 can be smaller than the diameter d2 of the 2-3 through holes S23 in the second surface 1404, which is the surface opposite to the first surface 1402, and a step 1406 can be formed on the inner wall of the 2-3 through holes S23. Therefore, the head of the second connecting member 1320 can be disposed on the step 1406 formed on the inner wall of the 2-3 through holes S23.

[0122] Here, the cover member 1400 may include an insulating material, such as a plastic material. Therefore, since the head of the second connecting member 1320 is in contact with the cover member 1400, the first panel 1212, which includes metal, can be insulated from the head of the second connecting member 1320, thereby improving the pressure resistance of the thermoelectric module 1200.

[0123] Furthermore, when the cover member 1400 comprises a plastic material, it can be easily molded into various sizes and shapes. More specifically, the cover member 1400 can be a plastic material used at high temperatures, such as polyphenylene sulfide (PPS). Therefore, the problem of deformation of the shape of the cover member 1400 due to the high temperature of the secondary fluid can be prevented.

[0124] As described above, since the cover member 1400 and the first panel 1212 are connected by a connecting member 1320 passing through a plurality of 2-3 through holes S23, the area including the plurality of 2-3 through holes S23 can be referred to as the connecting portion 1400A. The connecting portion 1400A includes a first side surface 1410 closest to the thermoelectric element 1210 and a second side surface 1420 opposite to the first side surface 1410. The second side surface 1420 of the cover member 1400 may extend along the edge E1 of the first panel 1212 (e.g., Figure 7(As shown) The first panel 1212 is configured such that, of the four edges of the first panel 1212, the edge E1 of the first panel 1212 can be located in the second region A2, and can be the edge in a direction parallel to the direction in which the plurality of connector components 210 and 220 are located. As described above, when the second side surface 1420 of the cover member 1400 is positioned along the edge E1 of the first panel 1212, the cover member 1400 presses down on the edge E1 of the first panel 1212, thus preventing the edge of the thermoelectric module 1200 from lifting off the fluid inlet 1100. In this case, a first groove 1412 recessed toward the second side surface 1420 can be formed in the first side surface 1410 of the cover member 1400, and a second groove 1422 recessed toward the first side surface 1410 can be formed in the second side surface 1420. As described above, when all grooves are formed in the first side surface 1410 and the second side surface 1420 of the cover member 1400, thermal stress is applied to both side surfaces of the cover member 1400 in a balanced manner, thus preventing the cover member 1400 from deforming due to an imbalance of thermal stress. In this case, the width B1 of the first groove 1412 is greater than the width B2 of the second groove 1422. For example, the width B1 of the first groove 1412 can be 1.5 to 3 times the width B2 of the second groove 1422. As described above, when the width B1 of the first groove 1412 is greater than the width B2 of the second groove 1422, the wires W1 and W2 can be easily connected to the connector parts 210 and 220. Furthermore, when the width B1 of the first groove 1412 provided near the connector components 210 and 220 is greater than the width B2 of the second groove 1422, the heat generated from the connector components 210 and 220 can be effectively discharged through the first groove 1412, and the rigidity of the cover member 1400 can be maintained by the second side surface 1420. Additionally, when the width of the second groove 1422 provided near the edge E1 of the first panel 1212 is less than the width of the first groove 1412, the contact area between the cover member 1400 and the edge E1 of the first panel 1212 increases on the edge E1 of the first panel 1212, resulting in a larger force exerted by the cover member 1400 on the edge E1 of the first panel 1212. This increases the bonding force between the edge E1 of the first panel 1212 of the thermoelectric module 1200 and the fluid inflow portion 1100, and prevents the edge E1 of the first panel 1212 of the thermoelectric module 1200 from being lifted.

[0125] Specifically, the cover member 1400 may be disposed on at least a portion of the connector components 210 and 220. As described above, when the connector components 210 and 220 include a first connector 210 and a second connector 220 spaced apart from each other, at least a portion of the first connector 210 and the second connector 220 may be disposed in the first recess 1412. Therefore, one end or the other end of the first connector 210 exposed by the first recess 1412 and one end or the other end of the second connector 220 exposed by the first recess 1412 can be easily connected to the wires W1 and W2. In other words, since the cover member 1400 can be fixed to the first panel 1212 of the thermoelectric module 1200, and the wires W1 and W2 can be connected, the wires W1 and W2 can be replaced or their connection paths can be changed.

[0126] In this case, since connector components 210 and 220 include a first connector 210 and a second connector 220, and the first connector 210 and the second connector 220 are set to be at the same distance h2 from the edge E1 of the first panel 1212, the cover member 1400 may include a first cover region 1430 disposed on at least a portion of the first connector 210 and a second cover region 1432 disposed on at least a portion of the second connector 220, and a first groove 1412 may be disposed between the first cover region 1430 and the second cover region 1432.

[0127] In this case, such as Figure 11 As shown, the distal ends of the first connector 210 and the second connector 220 can be configured to protrude from the side surfaces of the first cover region 1430 and the second cover region 1432. For example, the width C1 of each of the first cover region 1430 and the second cover region 1432 can be 0.8 to 0.95 times, preferably 0.85 to 0.9 times, the width C2 of each of the first cover region 1430 and the second cover region 1432. Therefore, each of the first cover region 1430 and the second cover region 1432 can protect each of the first connector 210 and the second connector 220 from external heat, etc., and the wires W1 and W2 can be easily connected. However, when the wires W1 and W2 are easily connected, the width C1 of each of the first cover region 1430 and the second cover region 1432 can be 0.8 to 1.1 times the width C2 of each of the first connector 210 and the second connector 220. Therefore, the first cover region 1430 and the second cover region 1432 can protect each of the first connector 210 and the second connector 220 from external heat and the like, and can also more effectively prevent damage to torsion caused by temperature differences applied to the thermoelectric module and / or occurring in the thermoelectric module.

[0128] In this configuration, the surfaces of the first cover region 1430 and the second cover region 1432 facing the connectors 210 and 220 can be configured to be spaced apart from the connectors 210 and 220. Therefore, the first cover region 1430 and the second cover region 1432 can protect the connectors 210 and 220 from external physical pressure, moisture, secondary fluids, or contaminants, and the first cover region 1430 and the second cover region 1432 can block the possibility of contact between the connectors 210 and 220 and the shielding member made of metallic material, thereby increasing the withstand voltage of the thermoelectric module 1200.

[0129] Simultaneously, the distal ends of each of the first cover region 1430 and the second cover region 1432 can be bent toward the first panel 1212. In other words, the cover member 1400 may also include a first guide region 1440 and a second guide region 1442 protruding from the first cover region 1430 and the second cover region 1432 toward the first panel 1212. The first guide region 1440 may be disposed on the side surface of the first connector 210, and the second guide region 1442 may be disposed on the side surface of the second connector 220. Therefore, it is possible to prevent the wires W1 and W2 connected to the first connector 210 and the second connector 220 from being pushed toward the electrodes of the thermoelectric element or from being separated. In this case, the first guide region 1440 and the second guide region 1442 may contact the first panel 1212. Therefore, since pressure can be applied to the first panel 1212 through the first guide region 1440 and the second guide region 1442, the engagement force between the first panel 1212 and the fluid inlet 1100 can be increased. As described above, the first cover region 1430 can be connected to the first guide region 1440, and the second cover region 1432 can be connected to the second guide region 1442. In this case, each of the first cover region 1430 and the second cover region 1432 can support each of the first guide region 1440 and the second guide region 1442. When the width C1 of each of the first cover region 1430 and the second cover region 1432 is within a predetermined range, for example, 0.85 times or greater than the width C2 of each of the first connector 210 and the second connector 220, the cover member 1400 can have high rigidity capable of supporting each of the first guide region 1440 and the second guide region 1442.

[0130] Furthermore, according to an embodiment of the present invention, in the connecting portion 1400A of the cover member 1400, the first surface 1402 of the two surfaces of the connecting portion 1400A facing the first panel 1212 can contact the first panel 1212, and a plurality of grooves R can be formed in the first surface 1402 at regular intervals. Therefore, the cover member 1400 is easy to injection mold, and deformation due to thermal deformation can be prevented even while reducing the amount of material used to mold the cover member 1400 and the weight of the cover member 1400, and the first panel 1212 can be pressed evenly relative to the entire area of ​​the cover member 1400.

[0131] Meanwhile, according to an embodiment of the present invention, the second groove 1422 of the cover member 1400 may include a curved surface with a predetermined curvature, and a third groove G may be formed in the edge E1 of the first panel 1212. The second groove 1422 and the third groove G may be configured to correspond to each other. In other words, the second groove 1422 and the third groove G may have the same size and shape, and may be aligned at the same position on the first surface 1110 of the fluid inflow portion 1100. Therefore, when the thermoelectric module 1200 is disposed on the fluid inflow portion 1100 and then the cover member 1400 is disposed, the position of the cover member 1400 is easily guided.

[0132] Furthermore, the thermal stress of the first panel 1212 can be reduced by the second groove 1422 of the cover member 1400 and the third groove G formed on the edge E1 of the first panel 1212, thereby reducing the thermal deformation of the first panel 1212 and thus increasing the bonding force between the first panel 1212 and the fluid inflow portion 1100.

[0133] Specifically, at least one of the second groove 1422 and the third groove G can be a smooth curved shape with a predetermined curvature. As described above, this prevents the problem of thermal stress concentration at the corners, thereby further enhancing the thermal stress relief performance of the first panel 1212.

[0134] Here, a second groove 1422 can be formed between the plurality of 2-3 through holes S23 formed on both sides of the cover member 1400, and a third groove G can be formed between the first connector 210 and the second connector 220 disposed in the second region A2 of the first panel 1212. In this case, the depth h1 of the third groove G can be less than the distance h2 from the edge E1 of the first panel 1212 to the connectors 210 and 220. Therefore, the bonding force between the first panel 1212 and the fluid inflow portion 1100 can be maintained, and the pressure resistance of the thermoelectric module 1200 can be enhanced.

[0135] like Figures 5 to 12As shown, multiple thermoelectric modules 1200 are disposed on the fluid inlet 1100, and cover members 1400 are disposed on connector parts 210 and 220. The multiple thermoelectric modules 1200, cover members 1400, and fluid inlet 1100 are connected by connecting members 1300. Then, the multiple thermoelectric modules 1200 are connected to wires W1 and W2. Subsequently, shielding members 1500 are also provided to prevent moisture or contaminants from penetrating into the multiple thermoelectric modules 1200.

[0136] Figure 13 This is a top view, in which multiple thermoelectric modules are arranged on one surface of the fluid inflow section included in the power generation device according to an embodiment of the present invention, wires are connected to connectors, and then a shielding member is provided. Figure 14 yes Figure 12 A three-dimensional view of the shielding components. Figure 15 It is shown in Figure 14 A view of the area on the shielding member where the sealing member is applied. Figure 16 yes Figure 14 A cross-sectional view of the shielding component along line A-A'. Figure 17 This is a perspective view of a shielding member according to another embodiment of the present invention.

[0137] For reference Figures 5 to 12 The thermoelectric element 1210 is disposed on a surface 1110 of the fluid inlet 1100, and the heat sink 1220 is disposed on the thermoelectric element 1210. As described above, the thermoelectric element 1210 includes a first panel 110 disposed on a surface 1110 of the fluid inlet 1100, a first electrode 120 disposed on the first panel 110, semiconductor elements 130 and 140 disposed on the first electrode 120, a second electrode 150 disposed on the semiconductor elements 130 and 140, and a second panel 160 disposed on the second electrode 150, and the heat sink 1220 may be disposed on the second panel 160.

[0138] refer to Figures 13 to 17A shielding member 1500 is disposed on the thermoelectric element 1210. In this case, to allow the second fluid to pass through the heat sink 1220, a first through-hole 1502 can be formed in the shielding member 1500. The edge of the first through-hole 1502 can be disposed in the second panel of the thermoelectric element 1210, and the heat sink 1220 can be exposed through the first through-hole 1502. In other words, the edge of the first through-hole 1502 can be disposed on the second panel of the thermoelectric element 1210, and the heat sink 1220 can pass through the first through-hole 1502. Therefore, since the second fluid can pass directly through the heat sink 1220, even though the interior of the thermoelectric element 1210 can be protected from external contaminants, moisture, and the second fluid, heat can be effectively exchanged between the second fluid and the heat sink 1220. In this case, the edge of the first through hole 1502 can be set on the second panel of the thermoelectric element 1210, and the size of the first through hole 1502 can be smaller than the size of the second panel of the thermoelectric element 1210 and larger than the size of the heat sink 1220 (i.e. the size of the surface of the heat sink 1220 set on the second panel), so that the heat sink 1220 can pass through the first through hole 1502.

[0139] Meanwhile, as shown in the figure, multiple thermoelectric elements 1210 can be disposed on one surface 1110 of the fluid inflow portion 1100, and a heat sink 1220 can be disposed on each thermoelectric element 1210. For this purpose, multiple first through holes 1502 can be formed in the shielding member 1500, the edge of each first through hole 1502 can be disposed on the second panel of each thermoelectric element 1210, and each heat sink 1220 can pass through each first through hole 1502. Therefore, since multiple thermoelectric elements 1210 can be covered by a single shielding member 1500, the process and structure of assembling the shielding member 1500 can be simplified.

[0140] At the same time, such as Figure 15 As shown, the sealing member 1600 can be disposed on the second panel along the edge of the first through hole 1502 formed in the shielding member 1500. In other words, the sealing member 1600 can be disposed between the first through hole 1502 and the heat sink 1220. Furthermore, a sealing member 1610 can also be disposed along at least a portion of the edge of the shielding member 1500. Here, the sealing members 1600 and 1610 can be a sealing material or sealing tape containing heat-resistant silicone resin. Therefore, moisture, secondary fluids, or contaminants can be prevented from penetrating into the thermoelectric element 1210.

[0141] According to an embodiment of the invention, a plurality of second through holes 1504 may also be formed in the shielding member 1500. In this case, at least a portion of the plurality of second through holes 1504 may be configured such that the regions where connectors 210 and 220 are disposed in the second region A2 of the first panel 1212 of each thermoelectric element 1210 overlap in the vertical direction. Here, verticality may refer to a direction parallel to the direction from the first panel 110 to the second panel 160 of each thermoelectric element 1210. Therefore, since the shielding member 1500 made of metallic material is not disposed on at least a portion of the connectors 210 and 220, the pressure resistance characteristics of the thermoelectric element 1210 can be enhanced. In this case, the plurality of second through holes 1504 may be sealed by the sealing member 1620.

[0142] More specifically, see reference Figure 13 One of the multiple second through holes 1504, 1504-1, can be formed to overlap with the first connector 210 in the vertical direction, and another second through hole 1504-2 can be formed to overlap with the second connector 220 in the vertical direction. Figure 13 In the enlarged view, a portion of the cover member 1400 needs to be actually shown through the second through holes 1504-1 and 1504-2 of the shielding member 1500. However, for better understanding, all connectors 210 and 220 disposed below the shielding member 1500 and the cover member 1400 are shown. In this case, the width C3 of each second through hole 1504 can be greater than the width C2 of the first connector 210 or the second connector 220. Therefore, the edge of each second through hole 1504 can be configured not to overlap with the first connector 210 or the second connector 220 in the vertical direction. Thus, since the shielding member 1500, made of metallic material, is not disposed on the first connector 210 or the second connector 220, the pressure resistance characteristics of the thermoelectric element 1210 can be enhanced, and the heat generated from the first connector 210 or the second connector 220 will not be transferred through the shielding member 1500 and can be discharged to the outside through the second through holes 1504-1 and 1504-2.

[0143] In this case, as referenced above Figure 11 and Figure 12The cover member 1400 can be disposed on the upper surfaces of connector components 210 and 220. In other words, according to an embodiment of the invention, for a thermoelectric element 1210, the cover member 1400 can be disposed on the upper surfaces of the first connector 210 and the second connector 220, and the shielding member 1500 can be disposed on the thermoelectric element 1210 and the cover member 1400. The second through holes 1504-1 and 1504-2 of the shielding member 1500 can be disposed in each of the upper surfaces of the first connector 210 and the second connector 220 where the cover member 1400 is disposed. In other words, the first cover region 1430 of the cover member 1400 can be disposed on the first connector 210, and the second cover region 1432 of the cover member 1400 can be disposed on the second connector 220. The first cover region 1430 and the second cover region 1432 can be configured to overlap with the second through holes 1504-1 and 1504-2 of the shielding member 1500 in the vertical direction. Therefore, the first cover region 1430 and the second cover region 1432 not only physically protect the first connector 210 and the second connector 220, but also provide rigidity for the first guide region 1440 and the second guide region 1442 to prevent the wires connected to the first connector 210 and the second connector 220 from separating. Here, the area of ​​each second through hole 1504 can be smaller than the area of ​​each first through hole 1502. Therefore, the second through hole 1504 can be easily filled with the sealing member 1620, and moisture, second fluid, or contaminants can be prevented from penetrating into the second through hole 1504.

[0144] Meanwhile, according to an embodiment of the present invention, the shielding member 1500 may be formed with a step. In other words, the shielding member 1500 may include a first shielding region 1510 disposed on a surface 1110 of the fluid inflow portion 1100, a second shielding region 1520 connected to the first shielding region 1510 and including the region formed by the first through hole 1502, a third shielding region 1530 connected to the second shielding region 1520 and including the region formed by a plurality of second through holes 1504, and a fourth shielding region 1540 connected to the third shielding region 1503 and disposed on a surface 1110 of the fluid inflow portion 1100. In this case, the first shielding region 1510 and the fourth shielding region 1540 may be disposed on a surface 1110 of the fluid inflow portion 1100, the second shielding region 1520 may be disposed on the second panel of the thermoelectric element 1210, and the third shielding region 1530 may be disposed on the connectors 210 and 220. Therefore, relative to one surface 1110 of the fluid inlet 1100, the height of the second shielding region 1520 can be set to be greater than the heights of the first shielding region 1510 and the fourth shielding region 1540. Furthermore, since the heights of connectors 210 and 220 are greater than the height of the second panel of the thermoelectric element 1210, the third shielding region 1530 can be positioned higher than the first shielding region 1510, the second shielding region 1520, and the fourth shielding region 1540. Therefore, the shielding member 1500 can protect the fluid inlet 1100 and the thermoelectric element 1210 while minimizing the flow resistance of the second fluid.

[0145] Furthermore, the shielding member 1500 may also include a support region 1550 extending from the first shielding region 1510 and disposed on a surface 1130 perpendicular to a surface 1110 of the fluid inflow portion 1100. Therefore, since the shielding member 1500 can be disposed in a "┐" shape on the fluid inflow portion 1100, misalignment of the shielding member 1500 on a surface 1110 of the fluid inflow portion 1100 can be prevented, and assembly is easy. In this case, the support region 1550 may also include a plurality of support regions spaced apart from each other. Therefore, the material cost and weight of the shielding member 1500 can be reduced.

[0146] At the same time, such as Figure 17As shown, according to an embodiment of the present invention, a third through-hole 1506 may also be formed in the shielding member 1500. In this case, at least a portion of the third through-hole 1506 may be formed to overlap with the area where multiple wires W1 and W2 overlap in the third shielding region 1530 of the shielding member 1500. For example, the wires W1 and W2 connected to multiple thermoelectric modules 1200 may be pulled out to the outside. Optionally, multiple thermoelectric modules 1200 disposed on two surfaces of the fluid inlet 1100 may be connected in parallel or in series with each other via wires W1 and W2. In this case, a guide member (not shown) may be disposed at one end or the other end of the fluid inlet 1100 to guide the wires W1 and W2, and the multiple wires W1 and W2 may be guided by the guide member. In this case, the area where multiple wires W1 and W2 overlap may appear in a narrow space. To prevent the problem of needing to increase the height of the entire shielding member 1500 due to the overlap of multiple wires W1 and W2, the third through-hole 1506 may be formed to partially overlap with the area where multiple wires W1 and W2 overlap. Therefore, the problem of at least one of the multiple wires W1 and W2 needing to be bypassed due to the shielding member 1500 can be prevented. In this case, the third through-hole 1506 can be filled with a sealing member (not shown). Therefore, the problem of moisture, second fluid, or contaminants penetrating into the third through-hole 1506 can be prevented. For this purpose, the area of ​​the third through-hole 1506 can be smaller than the area of ​​one of the multiple first through-holes 1502 and larger than the area of ​​one of the multiple second through-holes 1504. In other words, since the first through-hole 1502 is the through-hole through which the radiator 1220 passes, the first through-hole 1502 has the largest size among the first to third through-holes, and preferably, the first through-hole 1502 is formed to be larger than the second through-hole 1504 because the third through-hole 1506 is located in the area where the wires overlap.

[0147] Alternatively, although not shown, a protrusion may be formed to at least partially overlap the area where multiple wires W1 and W2 overlap in the third shielding region 1530 of the shielding member 1500. Therefore, compared to forming the third through-hole 1506, the problem of at least one of the multiple wires W1 and W2 needing to be bypassed by the shielding member 1500 can be prevented, the problem of increased overall height of the shielding member 1500 due to the multiple wires W1 and W2 overlapping each other can be prevented, and the sealing process using individual sealing members can be reduced.

[0148] As described above, when the third through-hole 1506 or protrusion is formed in the area where multiple wires overlap, the problem of increasing the height of the entire shielding member 1500 can be prevented, thereby minimizing the problem of flow resistance of the second fluid generated by the shielding member 1500.

[0149] exist Figures 13 to 17The example described is an example of multiple thermoelectric modules 1200 and a shielding member 1500 disposed on a surface 1110 of a fluid inlet 1100. However, the present invention is not limited thereto. The multiple thermoelectric modules 1200 and the shielding member 1500 may also be configured to be symmetrical with respect to a surface 1110 of the fluid inlet 1100 and another surface 1120 opposite to that surface 1110.

[0150] Figure 18 This is a perspective view of a power generation device according to another embodiment of the present invention. Figure 19 This is a top view of a power generation device according to another embodiment of the present invention. Figure 20 This is an example in which multiple power generation devices are provided according to another embodiment of the present invention.

[0151] refer to Figure 18 and Figure 19 The plurality of thermoelectric modules 1200 and the shielding member 1500 can be configured to be symmetrical in the Y direction with respect to one surface 1110 of the fluid inlet 1100 and another surface 1120 spaced apart from the surface 1110 of the fluid inlet 1100. Components of the shielding member 1500 and the plurality of thermoelectric modules 1200 will be omitted from the reference. Figures 11 to 15 Repeated descriptions of content that are identical.

[0152] A shielding member 1500 disposed on one surface 1110 of the fluid inflow portion 1100 can be connected to one surface 1110 of the fluid inflow portion 1100 via a plurality of connecting members 1330. A shielding member 1500 disposed on another surface 1120 of the fluid inflow portion 1100 can be connected to the other surface 1120 of the fluid inflow portion 1100 via a plurality of connecting members 1340. For this purpose, a plurality of holes connecting to the plurality of connecting members 1330 can be formed in one surface 1110 of the fluid inflow portion 1100 and the shielding member 1500, and a plurality of holes connecting to the plurality of connecting members 1340 can be formed in the other surface 1120 of the fluid inflow portion 1100 and the shielding member 1500. In this case, the positions of the plurality of connecting members 1330 can be set to be offset from the positions of the plurality of connecting members 1340 in the Y direction. In other words, the plurality of holes formed in one surface 1110 of the fluid inlet 1100 and the shielding member 1500, which connect to the plurality of connecting members 1330, and the plurality of holes formed in another surface 1120 of the fluid inlet 1100 and the shielding member 1500, which connect to the plurality of connecting members 1340, can be configured to be staggered from each other in the Y direction. Here, when the plurality of holes are configured to be staggered from each other in the Y direction, this may mean that the extension lines of the plurality of connecting members 1330 and the plurality of connecting members 1340 in the Y direction are staggered from each other. When the plurality of holes are configured to be staggered from each other in the Y direction, this means that the plurality of connecting members 1330 and the plurality of connecting members 1340 are configured to be spaced apart from each other in the X direction. Therefore, since the connecting members 1330 and the connecting members 1340 do not intersect each other in the fluid inlet 1100, the thickness of the fluid inlet 1100 can be made small enough to connect only to one of the connecting members 1330 and the connecting members 1340. In other words, when the connecting member 1330 connected to one surface 1110 of the fluid inflow portion 1100 is configured to be offset from the connecting member 1340 connected to the other surface 1120 of the fluid inflow portion 1100, the connecting member 1330 and the connecting member 1340 will not intersect each other in the fluid inflow portion 1100. Therefore, the thickness of the fluid inflow portion 1100 in the Y direction can be made longer than the length of one of the connecting member 1330 and the connecting member 1340, and shorter than the length obtained by adding the lengths of the connecting member 1330 and the connecting member 1340.

[0153] Therefore, as Figure 20As shown, multiple power generation devices 1000-1, 1000-2, and 1000-3 can be densely arranged in a predetermined space. In other words, as the thickness of the fluid inflow portion 1100 in the Y direction decreases, the number of power generation devices arranged at predetermined distances in the Y direction can be increased. As the number of power generation devices that can be arranged within the predetermined distance increases, the amount of electricity generated per unit area or unit volume can be increased. For example, as in the embodiment of the present invention, when the positions of the multiple connecting members 1330 and the multiple connecting members 1340 are set to be staggered from each other in the Y direction, the thickness T1 of the fluid inflow portion 1100 in the Y direction can be at least 8 mm, preferably 8 mm to 20 mm, more preferably 8 mm to 15 mm, and even more preferably 8 mm to 12 mm. Therefore, the fluid inflow section 1100 included in the power generation device 1000-1 and the fluid inflow section 1100 included in the adjacent power generation device 1000-2 can each be provided with a minimum distance T2 of 28 mm, preferably 28 mm to 40 mm, more preferably 28 mm to 35 mm, and even more preferably 28 mm to 32 mm, and the distance T3 between one end of the power generation device 1000-1 and one end of the adjacent power generation device 1000-2 can be greater than or equal to 1 mm. As described above, when multiple power generation devices 1000-1, 1000-2, and 1000-3 are densely arranged in a predetermined space, the power generation in the predetermined space can be increased.

[0154] Furthermore, when the positions of the plurality of connecting members 1330 and the plurality of connecting members 1340 are offset in the Y direction, the length of each connecting member 1330 and 1340 can be greater than 1 / 2 of the thickness of the fluid inlet portion 1100. Therefore, the connection force and reliability between the connecting members 1330 and 1340 and the fluid inlet portion 1100 can be increased.

[0155] Although the above mainly describes the single thermoelectric module 1200 and the cover member 1400 disposed on the fluid inlet 1100, as Figures 8 to 10 As shown, multiple thermoelectric modules 1200 can be disposed on one surface of the fluid inlet 1100, and each thermoelectric module 1200 can be provided with a cover member 1400.

[0156] Throughout the specification, although thermoelectric elements 100 and 1210 are described as including a first panel 110, a first electrode 120, a P-type thermoelectric leg 130, an N-type thermoelectric leg 140, a second electrode 150, and a second panel 160, the definition of thermoelectric elements 100 and 1210 is not limited thereto. This also means that thermoelectric elements 100 and 1210 include a first electrode 120, a P-type thermoelectric leg 130, an N-type thermoelectric leg 140, a second electrode 150, and a second panel 160, and are disposed on the first panel 110.

[0157] Furthermore, throughout the specification, the power generation device 1000 has been described as including a fluid inlet 1100, a thermoelectric module 1200, a cover member 1400, and a shielding member 1500. The thermoelectric module 1200 includes a thermoelectric element 1210 and a radiator 1220. However, the invention is not limited thereto, and it may also mean that the thermoelectric module includes all of the fluid inlet 1100, thermoelectric element 1210, radiator 1220, cover member 1400, and shielding member 1500.

[0158] In the instruction manual, "width" can refer to the width in the direction in which multiple thermoelectric modules are arranged, i.e. Figure 19 and Figure 20 The width in the X direction is shown. For example, the width D of the cover member 1400, the width D′ of the first panel 1212, the width B1 of the first groove 1412 and the width B2 of the second groove 1422, the width C1 of each of the first cover region 1430 and the second cover region 1432, and the width C2 of each of the first connector 210 and the second connector 220 can refer to the width in the direction in which the multiple thermoelectric modules are arranged, that is, Figure 19 and Figure 20 The width in the X direction is shown.

[0159] Meanwhile, as described above, according to an embodiment of the present invention, a plurality of thermoelectric modules 1200 are disposed on the surface of the fluid inlet portion 1100. According to an embodiment of the present invention, a guide member 1700 is used to guide the wires connected to the plurality of thermoelectric modules 1200.

Figure 28 This is a view showing the area where a second shielding member is provided when multiple power generation devices are arranged in parallel according to an embodiment of the present invention.

[0161] refer to Figures 21 to 28A pair of guide members 1700-1 and 1700-2 are spaced apart from each other on the first surface 1110 of the fluid inflow portion 1100, and a plurality of thermoelectric modules 1200 are disposed between the pair of guide members 1700-1 and 1700-2. A pair of guide members 1700-3 and 1700-4 are also disposed on a second surface 1120 opposite to the first surface 1110 of the fluid inflow portion 1100, and a plurality of thermoelectric modules 1200 are disposed between the pair of guide members 1700-3 and 1700-4. The first guide member 1700-1 and the third guide member 1700-3 are disposed opposite to each other with the fluid inflow portion 1100 between them, and the second guide member 1700-2 and the fourth guide member 1700-4 are disposed opposite to each other with the fluid inflow portion 1100 between them.

[0162] Regarding the fluid inlet 1100 and the thermoelectric module 1200, repeated descriptions of the same content as above will be omitted.

[0163] According to an embodiment of the present invention, a first shielding member 1500 is disposed on a plurality of thermoelectric elements 1210 disposed on a surface 1110 of a fluid inflow portion 1100, and protects the plurality of thermoelectric elements 1210 from external moisture, contaminants, second fluids, etc. However, when the first shielding member 1500 is manufactured to be disposed on a plurality of thermoelectric elements 1210, there is a situation where empty spaces are generated between the first shielding member 1500 and the fluid inflow portion 1100 depending on the number of thermoelectric elements 1210. For example, when the number of thermoelectric elements 1210 disposed on a surface of the fluid inflow portion 1100 is sixteen and includes six first through holes 1502, such that the first shielding member 1500 can be disposed on six thermoelectric elements 1210, a total of three first shielding members 1500 are required to shield all thermoelectric elements 1210, but the thermoelectric elements 1210 may not be disposed in the space corresponding to two thermoelectric elements 1210, and this space remains empty. When an empty space is formed in the side surface of the thermoelectric element 1210, moisture, contaminants, or a second fluid may penetrate into it, thus reducing the performance of the thermoelectric module.

[0164] According to an embodiment of the present invention, the guide member 1700 is intended to be disposed on the side surface of the thermoelectric element 1210 to reduce empty space. Here, the guide member 1700 may refer to a structure having a similar size and shape to the thermoelectric element 1210 but not used as a thermoelectric element. Therefore, in the specification, the guide member may also be referred to as a virtual module, virtual component, or guide module.

[0165] According to an embodiment of the present invention, a guide member 1700 is disposed on the side surface of a plurality of thermoelectric modules 1200. When the direction in which the plurality of thermoelectric modules 1200 are disposed is referred to as the X direction, the guide member 1700 may be disposed in the X direction relative to the plurality of thermoelectric modules 1200. In this case, the width X1 of the guide member 1700 in the X direction may be 0.9 to 1.1 times, preferably 0.92 to 1.08 times, more preferably 0.94 to 1.06 times, and more preferably the same as the width X2 of each thermoelectric module 1200, and the height from one surface 1110 of the fluid inlet 1100 to the upper surface of the guide member 1700 may be 0.8 to 1 times, preferably 0.9 to 1 times, more preferably 0.95 to 1 times, and more preferably the same as the height from one surface 1110 of the fluid inlet 1100 to the upper surface of the second panel of each thermoelectric module 1200. Therefore, since a guide member with a size similar to that of the thermoelectric module can be provided on the fluid inlet 1100, the process of assembling the thermoelectric module 1200 and the guide member 1700 on the fluid inlet 1100 is easy. It is not necessary to have different manufacturing processes for the fluid inlet 1100 on which the guide member 1700 is located and the fluid inlet 1100 on which the guide member 1700 is not located, and the same first shielding member 1500 can be used for assembly. Furthermore, the empty space in the side surface of the thermoelectric module 1200 on the fluid inlet 1100 can be minimized, thereby reducing the possibility of moisture or a second fluid penetrating into the empty space.

[0166] In particular, such as Figure 24 and Figure 25As shown, the guide member 1700 may have a stepped structure. In other words, guide members 1700-1 and 1700-2 may include first regions 1700-1A and 1700-2A and second regions 1700-1B and 1700-2B. The first regions 1700-1A and 1700-2A are regions disposed on the edges, and the second regions 1700-1B and 1700-2B are regions surrounded by the first regions 1700-1A and 1700-2A. The second regions 1700-1B and 1700-2B may be formed to be thicker than the first regions 1700-1A and 1700-2A. For example, when the guide members 1700-1 and 1700-2 are disposed on one surface of the fluid inlet 1100, the height from one surface of the fluid inlet 1100 to the upper surface of the first regions 1700-1A and 1700-2A can be 0.8 times to 1 times, preferably 0.9 times to 1 times, more preferably 0.95 times to 1 times, and more preferably the same as the height from one surface of the fluid inlet 1100 to the upper surface of the second panel of the thermoelectric element 1210. The height from one surface of the fluid inlet 1100 to the upper surface of the second regions 1700-1B and 1700-2B can be greater than the height from one surface of the fluid inlet 1100 to the upper surface of the first regions 1700-1A and 1700-2A. Therefore, the edge of the first through hole 1502 of the first shielding member 1500 can be disposed in the first regions 1700-1A and 1700-2A of the guide members 1700-1 and 1700-2, just like the thermoelectric element 1210, and the second regions 1700-1B and 1700-2B can pass through the first through hole 1502 of the first shielding member 1500, just like the heat sink 1220. Thus, the empty space between the fluid inflow portion 1100 in the side surface of the thermoelectric element 1210 and the first shielding member 1500 can be minimized.

[0167] Furthermore, according to embodiments of the present invention, a guide member can be used to guide the wires connected to the connector.

[0168] More specifically, see reference Figure 24 and Figure 25 , Figure 24 This is a perspective view of the first guide member 1700-1 disposed on one side of the first surface 1110 of the fluid inlet 1100. Figure 25This is a perspective view of a second guide member 1700-2 disposed on the other side of the first surface 1110 of the fluid inlet 1100. Each guide member 1700 may have at least one groove 1702 extending along a first direction, and wires connected to connectors 210 and 220 can be guided in the X direction through the groove 1702. For this purpose, like the first panel 1212, the guide member 1700 may include a first guide region B1 disposed on the side surface of the first region A1 of the first panel 1212 and a second guide region B2 disposed on the side surface of the second region A2 of the first panel 1212 and protruding from the first guide region B1. Furthermore, the groove 1702 may be formed in the second guide region B2. Therefore, the wires W connected to connectors 210 and 220 disposed in the second region A2 of the first panel 1212 can be fixedly accommodated in the groove 1702 in the X direction.

[0169] Furthermore, multiple grooves 1702 and 1704 may also be formed in the second guide region B2 of the guide member 1700. In other words, another groove 1704 may also be formed adjacent to and extending parallel to one groove 1702. As described above, when multiple grooves 1702 and 1704 are formed in the second guide region B2, one of the multiple grooves 1702 and 1704 may be selectively used depending on the positions of the connectors 210 and 220.

[0170] Furthermore, according to an embodiment of the invention, the two holes 1706 and 1708 may also be formed in the first guide region B1 of each guide member 1700 along a Y direction perpendicular to the X direction. The wire W, connected to connectors 210 and 220 and guided through the groove 1702, can be guided through the two holes 1706 and 1708 in a second direction and then pulled out to the outside. For example, the wire W can be guided from the upper surface to the lower surface of the first guide region B1 through one hole 1706, and then guided back to the upper surface of the first guide region B1 through the other hole 1708. Therefore, the wire W can be secured by the guide member 1700, and the possibility of wire W separation can be minimized even in environments with frequent vibrations. Therefore, the width X3 of the second guiding region B2 in the first direction can be smaller than the width X1 of the first guiding region B1 in the X direction. The second guiding region B2 can be positioned on one side closer to the sides of the first guiding region B1 in the X direction, and the two holes 1706 and 1708 can be positioned on the other side closer to the sides of the first guiding region B1 in the X direction. Thus, the wire guided through the first groove 1702 in the X direction can easily pass through the two holes 1706 and 1708 in the Y direction after a vertical bend.

[0171] In this case, one side of the first guiding region B1 in the X direction can be the portion adjacent to the thermoelectric element 1210, and the other side of the first guiding region B1 in the X direction can be the portion facing the edge of the fluid inflow portion 1100. Therefore, the positions of the grooves 1702 and holes 1706 and 1708 formed in the first guiding member 1700-1 and the second guiding member 1700-2 on the two edges of the fluid inflow portion 1100 can be different from each other.

[0172] According to an embodiment of the present invention, a connecting member can be used to connect the guide member 1700 to the fluid inlet 1100. For this purpose, a plurality of through holes S31 can be formed in the fluid inlet 1100, and a plurality of through holes S32 corresponding to the plurality of through holes S31 can be formed in the first guiding region B1 of the guide member 1700. The guide member 1700 and the fluid inlet 1100 can be connected by a connecting member 1360 passing through the plurality of through holes S31 and the plurality of through holes S32. In this case, since the head of the connecting member 1360 can be disposed in the plurality of through holes S32, the inner wall surface of the plurality of through holes S32 can have a stepped structure. Furthermore, the virtual lines connecting the plurality of through holes S32 can form a predetermined polygon. For example, the virtual lines connecting the plurality of through holes S32 can form a rectangle or a square. Therefore, the bonding force can be distributed throughout the entire first guiding region B1.

[0173] Furthermore, according to an embodiment of the present invention, a second shielding member 1800 may be disposed on the guide member 1700. Therefore, the wire W guided along the guide member 1700 can be prevented from being exposed to moisture, a second fluid, or contaminants. Figure 21 and Figure 22 As shown, the second shielding member 1800 disposed on each of the first to fourth guide members 1700-1, 1700-2, 1700-3 and 1700-4 can be referred to as shielding members 1800-1, 1800-2, 1800-3 and 1800-4, as 2-1 to 2-4.

[0174] Figure 26 a and Figure 26 b is a perspective view of shielding component 1800-1 (2-1) and shielding component 1800-3 (2-2). Figure 26 c and Figure 26Figure d is a perspective view of shielding members 1800-2 (2-2) and 1800-4 (2-4). In this case, each second shielding member 1800 may include a first shielding surface 1810 disposed on the upper surface of the guide member 1700 and a second shielding surface 1820 protruding from the first shielding surface 1810 toward the first surface 1110 of the fluid inflow portion 1100. The second shielding surface 1820 may be disposed between a side surface of the guide member 1700 and a side surface of the thermoelectric element disposed adjacent to the guide member 1700, and the edges of the second shielding surface 1820 and the first shielding surface 1810 may be sealed by a sealing member (not shown). Therefore, moisture, a second fluid, or contaminants can be prevented from penetrating into the thermoelectric element.

[0175] Although not shown, a heat insulation member may also be provided between the fluid inlet 1100 and the second shielding member 1800, or between the side surface of the guide member 1700 and the side surface of the thermoelectric element disposed adjacent to the guide member 1700. In this case, the heat insulation member may be provided between a surface 1110 of the fluid inlet 1100 and the second shielding surface 1820. Therefore, heat from the second fluid flowing along the second shielding member 1800 can be prevented from being transferred to the fluid inlet 1100 through the second shielding member 1800.

[0176] Meanwhile, the second shielding member 1800 can be connected to the guide member 1700 using the connecting member 1370. For this purpose, a plurality of through holes S42 can be formed in the first guide region B1 of the guide member 1700, and a plurality of through holes S43 corresponding to the plurality of through holes S42 can be formed in the second shielding member 1800. The second shielding member 1800 can be connected to the guide member 1700 through the connecting member 1360 passing through the plurality of through holes S42 and the plurality of through holes S43.

[0177] Therefore, not only the plurality of through holes S32 connected to the fluid inlet 1100, but also the plurality of through holes connected to the second shielding member 1800 can be formed in the first guiding region B1 of the guiding member 1700. Similar to the plurality of through holes S32, the plurality of through holes S42 can also be configured such that the virtual lines connecting the plurality of through holes S42 form a predetermined polygonal shape, such as a rectangle or a square. In this case, in a first guiding region B1, the plurality of through holes S32 and the plurality of through holes S42 can be configured to be staggered from each other in the X direction or the Y direction. For example, the plurality of through holes S42 in a row can be disposed between the plurality of through holes S32 in two rows, and the plurality of through holes S42 in a row can be disposed between the plurality of through holes S32 in two rows. Therefore, the connection force between the guiding member 1700 and the fluid inlet 1100 and the connection force between the guiding member 1700 and the second shielding member 1800 can be balanced.

[0178] Meanwhile, in the power generation device according to an embodiment of the present invention, the first guide member 1700-1 may be disposed on one side of the first surface 1110 of the fluid inflow portion 1100, and the second guide member 1700-1 may be disposed on the other side thereof. Each of the shielding member 1800-1 (2-1) and the shielding member 1800-2 (2-2) may be disposed on each of the first guide member 1700-1 and the second guide member. As described above, the positions of the grooves 1702 and holes 1706 and 1708 formed in the first guide member 1700-1 and the positions of the grooves 1702 and holes 1706 and 1708 formed in the second guide member 1700-2 may be different from each other. Similarly, at least one of the shape, position, and number of the plurality of through holes S32 and S42 formed in the first guide member 1700-1 may be different from at least one of the shape, position, and number of the plurality of through holes S32 and S42 formed in the second guide member 1700-2. The position and number of multiple through holes S32 and S42 can be varied to effectively guide the wires and distribute the connection force evenly.

[0179] As described above, in the power generation device according to an embodiment of the present invention, the first guide member 1700-1 may be disposed on one side of the first surface 1110 of the fluid inflow portion 1100, the second guide member 1700-2 may be disposed on the other side thereon, the third guide member 1700-3 may be disposed on one side of the second surface 1120, and the fourth guide member 1700-4 may be disposed on the other side thereon. Furthermore, each of the shielding members 2-1 (1800-1), 2-2 (1800-2), 2-3 (1800-3), and 2-4 (1800-4) may be disposed on each of the first guide member 1700-1, the second guide member 1700-2, the third guide member 1700-3, and the fourth guide member 1700-4.

[0180] The first guide member 1700-1 and the third guide member 1700-3 are disposed opposite to each other, with a fluid inflow portion 1100 between them. The second guide member 1700-2 and the fourth guide member 1700-4 can also be disposed opposite to each other, with a fluid inflow portion 1100 between them. Furthermore, each of the shielding members 2-1 (1800-1), 2-2 (1800-2), 2-3 (1800-3), and 2-4 (1800-4) may also include a third shielding surface 1830 extending from the first shielding surface 1810 and disposed on the third surface 1130 of the fluid inflow portion 1100. Furthermore, the wire W can be extracted from at least one gap between the third shielding surface 1830 of shielding member 2-1 1800-1 and the third shielding surface 1830 of shielding member 2-3 1800-3, and between the third shielding surface 1830 of shielding member 2-2 1800-2 and the third shielding surface 1830 of shielding member 2-4 1800-4, and at least one gap between the third shielding surface 1830 of shielding member 2-1 1800-1 and the third shielding surface 1830 of shielding member 2-3 1800-3, and between the third shielding surface 1830 of shielding member 2-2 1800-2 and the third shielding surface 1830 of shielding member 2-4 1800-4 can be sealed by a sealing member (not shown).

[0181] When multiple power generation devices are installed in a predetermined space, the power generation efficiency can be increased as the number of power generation devices accommodated per unit volume increases. Therefore, it is necessary to effectively accommodate multiple power generation devices.

[0182] According to an embodiment of the present invention, the positions of the plurality of through holes S42 of the first guide member 1700-1 and the plurality of through holes S42 of the third guide member 1700-3 can be staggered from each other, and the positions of the plurality of through holes S43 of the 2-1 shielding member 1800-1 and the plurality of through holes S43 of the 2-3 shielding member 1800-3 can be staggered from each other. Similarly, the positions of the plurality of through holes S42 of the second guide member 1700-2 and the plurality of through holes S42 of the fourth guide member 1700-4 can be staggered from each other, and the positions of the plurality of through holes S43 of the 2-2 shielding member 1800-2 and the plurality of through holes S43 of the 2-4 shielding member 1800-4 can be staggered from each other. Therefore, as Figure 28 As shown, when multiple power generation devices are connected in parallel, even when the spacing between the power generation devices becomes narrower, the possibility of contact between the connecting members of the shielding member connected to another power generation device can be reduced. Therefore, interference between different power generation devices can be reduced, and the power generation performance per unit volume can be improved.

[0183] In this specification, power generation devices, including thermoelectric modules or Peltier devices, may be collectively referred to as thermoelectric devices.

[0184] Power generation systems can generate electricity from heat sources such as ships, automobiles, power plants, and geothermal energy, and can incorporate multiple power generation units to effectively pool the heat. In this scenario, each power generation unit can improve the cooling performance of the cryogenic section of the thermoelectric element by increasing the bonding force between the thermoelectric module and the fluid inflow section, thereby enhancing the efficiency and reliability of the power generation unit. This, in turn, can improve the fuel efficiency of transportation equipment (such as ships or vehicles). Therefore, in the shipping and transportation industries, when power generation units are applied to manufacturing industries (such as steel mills), it can reduce transportation costs, create an eco-friendly industrial environment, and lower material costs.
