Description

High-efficiency heat exchange structure for thermoelectric power generation

[0001] The present invention relates to a high-efficiency heat exchange structure for thermoelectric power generation, and more specifically, to a high-efficiency heat exchange structure for thermoelectric power generation for extracting high temperatures for thermoelectric power generation more effectively and efficiently.

[0002] A thermoelectric element is a general term for devices that utilize various effects resulting from the interaction of heat and electricity. Examples include thermistors, which are devices with a negative resistance temperature coefficient characteristic where electrical resistance decreases as temperature increases; devices utilizing the Seebeck effect, a phenomenon in which an electromotive force is generated by a temperature difference; and devices utilizing the Peltier effect, a phenomenon in which heat is absorbed (or generated) by an electric current.

[0003]

[0004] Here, a device made to perform a cooling function similar to that of a Freon compressor or an endothermic refrigerator using a small solid-state device as a thermoelectric heat pump by utilizing the Peltier effect will be referred to as a thermoelectric device.

[0005]

[0006] The Peltier effect is a phenomenon in which, when a direct current power source is applied to two different electrical conductors, one side heats up and the other side cools down depending on the direction of the current. This phenomenon occurs because electrons absorb thermal energy to raise their energy levels as they move from one semiconductor to the other.

[0007]

[0008] Thermoelectric power generation is an eco-friendly power generation system that utilizes temperature differences, and its performance largely depends on how efficiently the heat source to be utilized is transferred to the thermoelectric power generation device.

[0009]

[0010] In particular, air convection heat at around 400 degrees Celsius, which has an extremely low regeneration rate, is currently hardly being regenerated.

[0011]

[0012] Since such unused convective heat takes on various forms depending on the characteristics of the source, it is crucial to thoroughly understand the properties of air convection to ensure an optimal heat-absorbing structure for heat flow. Nevertheless, proposals for heat exchange structures capable of effectively extracting high-temperature air convective heat sources, which currently exhibit the most widespread applications, remain minimal.

[0013]

[0014] Due to such problems, the inventor has proposed a heat exchange structure that is utilized in thermoelectric power generation using high-temperature air convection as a heat source for the high-temperature section, capable of collecting a constant and large amount of heat from the element end even with vertical and horizontal convection.

[0015] Therefore, the present invention is proposed to improve upon such conventional problems and aims to solve the problem of providing a new type of high-efficiency heat exchange structure for thermoelectric power generation to extract high temperatures for thermoelectric power generation more effectively and efficiently.

[0016]

[0017] In particular, the objective is to provide a new type of high-efficiency heat exchange structure for thermoelectric power generation that allows heat to be effectively and efficiently extracted by forming a plurality of heat extraction fins, which are spaced apart at intervals set in a direction perpendicular to one side of a coupling plate.

[0018] According to the features of the present invention for achieving the above-described purpose, a heat exchange structure (100) is installed on one side of a thermoelectric semiconductor (1) to absorb heat passing through the passage and to increase thermal efficiency, wherein the heat exchange structure (100) is characterized by comprising: a coupling plate (200) formed on one side of the thermoelectric semiconductor (1) and formed in a plate shape; and a plurality of heat collection pins (300) spaced apart at intervals set in a direction perpendicular to one side of the coupling plate (200) and for collecting heat.

[0019]

[0020] In the high-efficiency heat exchange structure for thermoelectric power generation according to the present invention, the heat collection fins (300) of the heat exchange structure (100), which are installed facing each other on the wall of the passage, are positioned to intersect each other.

[0021]

[0022] In addition, in the high-efficiency heat exchange structure for thermoelectric power generation according to the present invention, the heat collection fin (300) is characterized by being formed at an angle so as to narrow from the upper side to the lower side.

[0023]

[0024] In addition, in the high-efficiency heat exchange structure for thermoelectric power generation according to the present invention, the heat exchange structure (100) is characterized by having a plurality of auxiliary heat collection fins (400) on the outside of the heat collection fin (300).

[0025]

[0026] In the high-efficiency heat exchange structure for thermoelectric power generation according to the present invention, the auxiliary heat collection fins (400) are characterized by being formed spaced apart in the upper and lower directions on the outer side of the heat collection fins (300), or formed in multiple numbers in the vertical direction on the outer side of the heat collection fins (300).

[0027]

[0028] In the high-efficiency heat exchange structure for thermoelectric power generation according to the present invention, the auxiliary heat collection fin (400) located farther away from the connecting plate (200) is characterized by being formed with a longer horizontal length from the heat collection fin (300).

[0029]

[0030] In addition, in the high-efficiency heat exchange structure for thermoelectric power generation according to the present invention, the heat exchange structure (100) is configured in a modular form including the coupling plate (200), heat collection fin (300), and auxiliary heat collection fin (400), wherein the coupling plate (200) is formed spaced apart so that the heat collection fin (300) and auxiliary heat collection fin (400) are positioned inwardly, and the heat exchange structure (100) is characterized by including a connecting member (500) for connecting the spaced-apart coupling plate (200) on both sides of the coupling plate (200).

[0031] As described above, the high-efficiency heat exchange structure for thermoelectric power generation according to the present invention has the effect of enabling heat extraction of high temperatures for thermoelectric power generation more effectively and efficiently.

[0032]

[0033] In particular, by forming a plurality of heat collection pins that are spaced apart at intervals set in a direction perpendicular to one side of the coupling plate and for collecting heat, the heat can be effectively and efficiently collected by the heat collection pins.

[0034]

[0035] In addition, by forming the heat collection fins at an angle so that they narrow from the upper side to the lower side, heat can be effectively collected by the widely formed heat collection fins even if the temperature on the upper side is low.

[0036]

[0037] In addition, by configuring auxiliary heat collection fins horizontally so as to be perpendicular to the heat collection fins, the heat contact area is widened, which has the effect of allowing more heat to be absorbed.

[0038]

[0039] In addition, by configuring the auxiliary heat fins located further away from the connecting plate to be longer horizontally from the heat fins compared to the auxiliary heat fins adjacent to the connecting plate, the heat contact area is expanded by the longer auxiliary heat fins, thereby enabling the absorption of more heat even if the temperature decreases towards the center.

[0040]

[0041] In addition, by configuring the heat exchange structure, which includes a connecting plate, heat collection fins, and auxiliary heat collection fins, in a modular form, when connecting multiple thermoelectric semiconductors to increase thermal efficiency, the modular heat exchange structure can be installed by simple coupling between the thermoelectric semiconductors, thereby enabling easy installation while effectively increasing thermal efficiency.

[0050] Figure 9 is a plan view of Figure 8.

[0051] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings, and in FIGS. 1 to 9, the same reference numerals are used for components that perform the same function. Meanwhile, in the drawings and detailed description, detailed descriptions and drawings of specific technical configurations and operations of elements not directly related to the technical features of the present invention have been omitted, and only the technical configurations related to the present invention have been briefly illustrated or described.

[0052]

[0053] Referring to FIGS. 1 to 9, the high-efficiency heat exchange structure (100) for thermoelectric power generation according to a preferred embodiment of the present invention is a heat exchange structure that is utilized for thermoelectric power generation using high-temperature air convection as a heat source for the high-temperature part, and is a heat exchange structure capable of collecting a constant amount of heat in both vertical and horizontal convection.

[0054]

[0055] The heat exchange structure (100) is preferably installed on the wall of a passage (2), such as a chimney, and is installed on one side of a thermoelectric semiconductor (1) to absorb heat passing through the passage (2) so as to increase thermal efficiency by collecting heat.

[0056]

[0057] The heat exchange structure (100) is formed in a plate shape and comprises a coupling plate (200) formed on one side of a thermoelectric semiconductor (1), and a plurality of heat collection pins (300) for collecting heat, which are spaced apart at intervals set in a direction perpendicular to one side of the coupling plate (200).

[0058]

[0059] Meanwhile, the heat collection pin (300) is formed to be inclined so as to narrow from the upper side to the lower side. This is to ensure that heat can be effectively collected by the heat collection pin (300) formed widely, even if the temperature of the upper side is low.

[0060]

[0061] When a heat exchange structure (100) including heat collection fins (300) having such a structure is installed on the wall of a passage (2), as shown in FIGS. 2 and FIGS. 3, the heat collection fins (300) are installed on the wall of the passage (2) so as to cross sequentially.

[0062]

[0063] As described above, the high-efficiency heat exchange structure for thermoelectric power generation according to the present invention has the effect of enabling heat extraction of high temperatures for thermoelectric power generation more effectively and efficiently.

[0064]

[0065] In particular, by forming a plurality of heat collection pins that are spaced apart at intervals set in a direction perpendicular to one side of the coupling plate and for collecting heat, the heat can be effectively and efficiently collected by the heat collection pins.

[0066]

[0067] In addition, by forming the heat collection fins at an angle so that they narrow from the upper side to the lower side, heat can be effectively collected by the widely formed heat collection fins even if the temperature on the upper side is low.

[0068]

[0069] Meanwhile, a high-efficiency heat exchange structure (100) for thermoelectric power generation according to a preferred embodiment of the present invention comprises a plurality of auxiliary heat collection fins (400) as shown in FIGS. 4 to 7.

[0070]

[0071] A plurality of auxiliary heat collection pins (400) are formed on both sides of the heat collection pin (300) and configured to collect heat.

[0072]

[0073] Meanwhile, the auxiliary heat collection pins (400) may be formed horizontally on the heat collection pins (300) as shown in FIG. 4 (a), and may be formed in multiple numbers spaced apart vertically.

[0074]

[0075] And, as shown in Fig. 4 (b), the auxiliary heat collection pins (400) may be formed in multiple numbers in the vertical direction on the outer side of the heat collection pins (300).

[0076]

[0077] Meanwhile, the auxiliary heat collection pin (400) may be formed with different lengths when formed outwardly on the heat collection pin (300) as shown in FIG. 5.

[0078]

[0079] Referring to FIG. 5, the length (L₁) of the auxiliary heat collection pin (400) adjacent to the coupling plate (200) may be formed to be shorter than the length (L₂) of the auxiliary heat collection pin (400) located far from the coupling plate (200).

[0080]

[0081] In this way, by configuring the auxiliary heat fins located further away from the connecting plate to be longer horizontally from the heat fins compared to the auxiliary heat fins adjacent to the connecting plate, the heat contact area is expanded by the longer auxiliary heat fins, thereby enabling the absorption of more heat even if the temperature decreases towards the center.

[0082]

[0083] When a heat exchange structure (100) having auxiliary heat collection fins (400) is installed on a passage (2), it is installed so as to face each other as described in FIGS. 1 to 3, but the heat collection fins (300) are installed to cross each other. At this time, at the same time as the heat collection fins (300) cross, the auxiliary heat collection fins (400) may also be positioned to cross each other with the facing auxiliary heat collection fins (400) as shown in FIGS. 6 and 7.

[0084]

[0085] As described above, by configuring the auxiliary heat collection fins horizontally so as to be perpendicular to the heat collection fins, the heat contact area is widened, allowing for the absorption of more heat.

[0086]

[0087] Meanwhile, a high-efficiency heat exchange structure (100) for thermoelectric power generation according to a preferred embodiment of the present invention may be configured in a modular manner, including a coupling plate (200), a heat collection fin (300), and an auxiliary heat collection fin (400).

[0088]

[0089] A heat exchange structure (100) configured in a modular manner is formed such that a connecting plate (200) is spaced apart so that a heat collection fin (300) and an auxiliary heat fin (400) are positioned inside, and includes a connecting member (500) for connecting the spaced connecting plates (200) on both sides of the connecting plate (200).

[0090]

[0091] A heat exchange structure (100) may be configured in a modular form by forming a connecting plate (200) that is spaced apart and faces each other, a connecting member (500) that connects both sides of the connecting plate (200), and a heat collection fin (300) and an auxiliary heat collection fin (400) formed on the inside of the connecting plate (200).

[0092]

[0093] Meanwhile, the connecting member (500) for connecting both sides of the connecting plate (200) is configured to be integral with the connecting plate (200) in a preferred embodiment of the present invention, but it may be configured separately as a separable or assembled type.

[0094]

[0095] In this way, by configuring a heat exchange structure including a connecting plate, heat collection fins, and auxiliary heat collection fins in a modular form, when connecting multiple thermoelectric semiconductors to increase thermal efficiency, the modular heat exchange structure can be installed by simple coupling between the thermoelectric semiconductors, thereby enabling easy installation while effectively increasing thermal efficiency.

[0105]

[0106] In the high-efficiency heat exchange structure for thermoelectric power generation according to the present invention, the auxiliary heat collection fins (400) are formed spaced apart in the upper and lower directions on the outer side of the heat collection fins (300), or are formed in multiple numbers in the vertical direction on the outer side of the heat collection fins (300) as a form for implementing the invention.

[0107]

[0108] In the high-efficiency heat exchange structure for thermoelectric power generation according to the present invention, the auxiliary heat collection fin (400) located farther away from the auxiliary heat collection fin (400) adjacent to the coupling plate (200) is formed to have a longer horizontal length from the heat collection fin (300) for the implementation of the invention.

[0109]

[0110] In addition, in the high-efficiency heat exchange structure for thermoelectric power generation according to the present invention, the heat exchange structure (100) is configured in a modular form including the coupling plate (200), heat collection fin (300), and auxiliary heat collection fin (400). In the modular heat exchange structure (100), the coupling plate (200) is formed spaced apart so that the heat collection fin (300) and the auxiliary heat collection fin (400) are positioned inwardly, and the invention is implemented in a form that includes a connecting member (500) for connecting the spaced-apart coupling plate (200) on both sides of the coupling plate (200).

[0118]

[0119] In addition, it is expected to be widely used in industry because, by configuring the auxiliary heat collection fins located further away from the connecting plate to be longer horizontally from the heat collection fins compared to the auxiliary heat collection fins adjacent to the connecting plate, the heat contact area is expanded by the longer auxiliary heat collection fins, thereby enabling the absorption of more heat even if the temperature decreases towards the center.
