Thermoelectric gas burner

Abstract

The present invention relates to a thermoelectric gas burner. In such a thermoelectric gas burner, the gas discharged from a gas cylinder comes into direct contact with the low-temperature part of the thermoelectric module to cool it, so that the low-temperature part of the thermoelectric module is directly contacted with a large amount of gas per unit time without providing a separate fan or cooling device for cooling the low-temperature part of the thermoelectric module, or the gas passes through the inside of the low-temperature part of the thermoelectric module. This allows the thermoelectric gas burner to be manufactured small and lightweight, and the temperature difference between the high-temperature part and the low-temperature part of the thermoelectric module is large, allowing a larger amount of electricity to be produced.

Description

[Technical field]

[0001] The present invention relates to a thermoelectric gas burner, and more particularly to a thermoelectric gas burner in which gas discharged from a gas cylinder comes into direct contact with a low-temperature part of a thermoelectric module to lower the temperature of the low-temperature part and then burns in the high-temperature part, thereby increasing the temperature difference between the low-temperature part and the high-temperature part that make up the thermoelectric module and enabling the production of a large amount of electricity. [Background technology]

[0002] A thermoelectric element is a device that can convert thermal energy into electrical energy by converting the temperature difference between both ends into electricity. The thermoelectric phenomenon of a thermoelectric element means the reversible and direct energy conversion between heat and electricity, and is a phenomenon that occurs when heat (phonons) are transferred by the movement of electrons and holes inside the material that constitutes the thermoelectric element.

[0003] Thermoelectric elements that use the thermoelectric phenomenon can be broadly classified into thermoelectric elements that use the Peltier effect for active cooling, and thermoelectric elements that use the Seebeck effect for waste heat power generation.

[0004] Among them, the demand and necessity of thermoelectric generating devices using the Seebeck effect of thermoelectric elements is increasing as a solution to environmental pollution problems and energy saving problems.

[0005] Such thermoelectric power generation devices are also applied in various ways to household appliances and devices, such as gas burners, stoves, or heating elements, and gas burners are now widely used in apartments and homes for heating or for cooking both indoors and outdoors, and in many places, where the power supply source is limited, gas burners are used for heating and cooking.

[0006] When using a gas burner, the waste heat remaining after heating the heat exchanger of the gas burner is sometimes simply released to the outside and wasted. Therefore, by applying a thermoelectric generator to a gas burner, the thermal energy of the wasted gas can be converted into electricity and used effectively as power for electric fans, lighting, televisions, chargers, etc.

[0007] On the other hand, it is preferable that a gas burner equipped with a thermoelectric generator (hereinafter referred to as a thermoelectric gas burner) is lightweight, small, highly portable, and capable of generating a large amount of electricity. However, conventional thermoelectric gas burners have the problem that they are large and heavy, and cannot generate a large amount of electricity due to their low conversion efficiency.

[0008] Therefore, it is necessary to develop a thermoelectric gas burner that is lightweight, compact, and capable of producing large amounts of electricity. Summary of the Invention [Problem to be solved by the invention]

[0035] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings and the accompanying claims. However, the present invention is not limited to the embodiments described herein, and may be embodied in other forms. Like reference numerals refer to like elements throughout the specification.

[0036] A thermoelectric gas burner 1 according to a first embodiment of the present invention will now be described. Fig. 1 is a cross-sectional view showing a thermoelectric gas burner according to a first embodiment of the present invention.

[0037] Referring to FIG. 1, the thermoelectric power generating gas burner (1) mainly includes a housing (100) and a thermoelectric module (200).

[0038] First, the housing (100) will be described. The housing (100) may have an inlet hole (110) formed on one side (the lower side as viewed in the drawing), and gas may be introduced into the inlet hole (110). The gas may be low-temperature compressed gas discharged from a gas cylinder of a gas burner. The housing (100) may also have a combustion hole (120) formed on the other side (the upper side as viewed in the drawing). Air may be introduced into the housing (100) through the combustion hole (120), and the air introduced into the combustion hole (120) may be mixed with gas and combusted in a high-temperature portion (220) of the thermoelectric module, which will be described later.

[0039] Meanwhile, a plurality of second heat dissipation fins (130) may be formed on the outer circumferential surface of the housing (100).

[0040] Next, the thermoelectric module 200 will be described. The thermoelectric module 200 includes a thermoelectric element 210, a high temperature section 220, and a low temperature section 230. The thermoelectric element 210 may be a conventional thermoelectric element using the Seebeck effect. The high temperature section 220 may be configured to burn gas and may be in contact with one side (upper side as viewed in the figure) of the thermoelectric element 210 to transfer heat to the thermoelectric element 210. The low temperature section 230 may be in contact with the other side (lower side as viewed in the figure) of the thermoelectric element 210 to cool the thermoelectric element 210.

[0041] The thermoelectric module (200) may be disposed inside the housing (100) such that the high temperature portion (220) faces the combustion hole (120) of the housing (100) and the low temperature portion (230) faces the inlet hole (110) of the housing (100). In this case, a plurality of first heat dissipation fins (232) may be formed on one side of the low temperature portion (230) facing the inlet hole (110).

[0042] Also, as shown in FIG. 1, the thermoelectric module (200) may be disposed inside the housing (100) such that a mixing flow path (10) is formed between the outer peripheral surface of the thermoelectric module (200) and the housing (100).

[0043] Next, the operation of the thermoelectric power generating gas burner (1) will be described.

[0044] Since the thermoelectric module 200 is disposed inside the housing 100, the gas flowing into the inlet 110 can directly contact the low temperature portion 230 and cool the low temperature portion 230. Since the gas flows into the inlet 110 at a high speed, the low temperature portion 230 can come into contact with a large amount of gas per unit time and be cooled.

[0045] At this time, since a plurality of first heat dissipation fins (232) are formed on one side of the low temperature portion (230) that comes into contact with the gas, the low temperature portion (230) can dissipate a larger amount of heat and cool when it comes into contact with the gas.

[0046] 1, the low temperature section (230) and the housing (100) may be connected by a first heat transfer member (20) capable of transferring heat. When the low temperature section (230) and the housing (100) are connected by the first heat transfer member (20), the heat of the low temperature section (230) may be transferred to the housing (100) and dissipated by the second heat dissipation fins (130).

[0047] The gas that has come into contact with and cooled the low temperature section (230) is transferred to the high temperature section (220) while being mixed with air along the mixing flow path (10). Since the high temperature section (220) is disposed opposite the combustion hole (120), the gas transferred to the high temperature section (220) can be mixed with the air flowing in from the combustion hole (120) and completely combusted.

[0048] A thermoelectric gas burner 2 according to a second embodiment of the present invention will now be described. Fig. 2 is a cross-sectional view showing a thermoelectric gas burner according to the second embodiment of the present invention.

[0049] Referring to FIG. 2, the thermoelectric power generating gas burner (2) mainly includes a housing (300) and a thermoelectric module (400).

[0050] First, a description will be given of the housing (300). The housing (300) may be formed with an inlet hole (310), a combustion hole (320), and a fourth heat dissipation fin (350), and may include a first bypass pipe (330) and a second bypass pipe (340).

[0051] The inlet hole 310 may be formed on one side (the lower side as viewed in the drawing) of the housing 300, and gas may be introduced into the inlet hole 310. The combustion hole 320 may be formed on the other side (the upper side as viewed in the drawing) of the housing 300, and air may be introduced into the housing 300 through the combustion hole 320. The air that has flowed into the combustion hole 320 may be mixed with gas and combusted in a high temperature portion 420 of the thermoelectric module, which will be described later.

[0052] Meanwhile, a plurality of fourth heat dissipation fins (350) may be formed on the outer circumferential surface of the housing (300).

[0053] Next, the thermoelectric module 400 will be described. The thermoelectric module 400 includes a thermoelectric element 410, a high temperature part 420, and a low temperature part 430. The thermoelectric element 410 may be a conventional thermoelectric element using the Seebeck effect. The high temperature part 420 may be configured to burn gas and may be in contact with one side (upper side as viewed in the figure) of the thermoelectric element 410 to transfer heat to the thermoelectric element 410. The low temperature part 430 may be in contact with the other side (lower side as viewed in the figure) of the thermoelectric element 410 to cool the thermoelectric element 410, and may have a gas passage 432 passing through the inside.

[0054] In this case, the first bypass pipe (330) may be configured so that one end is connected to the inlet hole (310) and the other end is connected to one end of the gas flow path (432), and the second bypass pipe (340) may be configured so that one end is connected to the inlet hole (310) and the other end is connected to the other end of the gas flow path (432).

[0055] On the other hand, as shown in FIG. 2, the distance between one end of the first bypass pipe (330) communicating with the inlet (310) and the low temperature section (430) may be greater than the distance between one end of the second bypass pipe (340) communicating with the inlet (310) and the low temperature section (430).

[0056] In addition, a plurality of third heat dissipation fins (434) may be formed on one side of the low temperature part (430) facing the inlet (310). The thermoelectric module (400) may be disposed inside the housing (300) such that the high temperature part (420) faces the combustion hole (320) of the housing (300) and the low temperature part (430) faces the inlet (310) of the housing (300).

[0057] Also, as shown in FIG. 2, the thermoelectric module (400) may be disposed inside the housing (300) such that a mixing flow path (30) is formed between the outer peripheral surface of the thermoelectric module (400) and the housing (300).

[0058] Next, the operation of the thermoelectric power generating gas burner (2) will be described.

[0059] When gas flows into the inlet (310), a portion of the gas flows into the first bypass pipe (330) and is transferred to the gas flow passage (432), and the gas transferred to the gas flow passage (432) cools the low temperature section (430) while passing through the inside of the low temperature section (430). The gas is discharged from the gas flow passage (432) and flows into the second bypass pipe (340) and is discharged to the inlet (310).

[0060] Meanwhile, the gas discharged from the second bypass pipe (340) to the inlet hole (310) absorbs heat while passing through the gas passage (432) and is therefore at a higher temperature than the gas flowing into the inlet hole (310) from outside the housing. When such high-temperature gas flows into the first bypass pipe (330) and is transferred to the gas passage (432), the cooling efficiency of the low-temperature section (430) may decrease. To prevent this, one end of the first bypass pipe (330) communicating with the inlet hole (310) is located farther from the low-temperature section (430) than one end of the second bypass pipe (340) communicating with the inlet hole (310), so that the gas discharged from the second bypass pipe (340) to the inlet hole (310) does not flow into the first bypass pipe (330).

[0061] The remaining gas that does not flow into the first bypass pipe (330) among the gas flowing into the inlet (310) and the gas discharged from the second bypass pipe (340) are both transferred to the low temperature section (430) and come into direct contact with the low temperature section (430) to cool the low temperature section (430). Since the gas flows into the inlet (310) at a high speed, the low temperature section (430) can come into contact with a large amount of gas per unit time and be cooled.

[0062] At this time, since a plurality of third heat dissipation fins (434) are formed on one side of the low temperature portion (430) that comes into contact with the gas, the low temperature portion (430) can dissipate a larger amount of heat and cool when it comes into contact with the gas.

[0063] In addition, the low temperature portion (430) and the housing (300) may be connected by a second heat transfer member 40 capable of transferring heat, and when the low temperature portion (430) and the housing (300) are connected by the second heat transfer member 40, the heat transferred from the low temperature portion (430) to the housing (300) may be dissipated by the fourth heat dissipation fin (350) of the housing (300) described above.

[0064] The gas that has cooled the low temperature section (430) is transferred to the high temperature section (420) while being mixed with air along the mixing flow path (30). Since the high temperature section (420) is disposed opposite the combustion hole (320), the gas transferred to the high temperature section (420) can be mixed with the air flowing in from the combustion hole (320) and completely combusted.

[0065] Hereinafter, a thermoelectric gas burner 3 according to a third embodiment of the present invention will be described. Fig. 3 is a cross-sectional view showing a thermoelectric gas burner according to the third embodiment of the present invention.

[0066] 3, the thermoelectric power-generating gas burner (3) mainly includes a housing (500), a burner (600), and a thermoelectric module (700). That is, in the first and second embodiments, the high temperature part of the thermoelectric module also serves as the burner, but in this embodiment, the burner and the high temperature part of the thermoelectric module are formed separately.

[0067] First, the housing (500) will be described. The housing (500) may have an inlet hole (510) and a combustion hole (520). The inlet hole (510) may be formed on one side (lower side as viewed in the drawing) of the housing (500), and gas may be introduced into the inlet hole (510). The combustion hole (520) may be formed on the other side (upper side as viewed in the drawing) of the housing (500), and air may be introduced into the housing (500) through the combustion hole (520). The air introduced into the combustion hole (520) may be mixed with gas and combusted in a burner (600) described below.

[0068] Next, the fire hole 600 will be described. The fire hole 600 may be disposed inside the housing 500 so as to face the combustion hole 520, and gas can be burned on one side of the fire hole 600 facing the combustion hole 520.

[0069] Also, as shown in FIG. 3, the nozzle (600) may be disposed inside the housing (500) such that a mixing flow passage (50) is formed between the outer circumferential surface of the nozzle (600) and the housing (500).

[0070] Next, the thermoelectric module (700) will be described. The thermoelectric module (700) includes a thermoelectric element (710), a high temperature part (720), and a low temperature part (730), and may be disposed outside the housing (500). The thermoelectric element (710) may be a conventional thermoelectric element using the Seebeck effect. One side (upper side as viewed in the drawing) of the high temperature part (720) may be connected to the burner (600) by a third heat transfer member (610). The third heat transfer member (610) may transfer heat generated in the burner (600) to the high temperature part (720). In addition, the other side (lower side as viewed in the drawing) of the high temperature part (720) may contact one side (upper side as viewed in the drawing) of the thermoelectric element (710) to transfer heat transferred from the burner (600) to the thermoelectric element (710). The low temperature portion (730) may be in contact with the other side (the lower side in the drawing) of the thermoelectric element (710) to cool the thermoelectric element (710), and the low temperature portion (730) may have a gas flow path (732) passing through it.

[0071] In addition, a plurality of fifth heat dissipation fins (734) may be formed on the surface of the low temperature portion (730) opposite to the surface in contact with the thermoelectric element (710).

[0072] Next, the operation of the thermoelectric power generating gas burner (3) will be described.

[0073] The gas flowing into one side of the gas passage (732) of the low temperature part (730) cools the low temperature part (730), and is then discharged to the other side of the gas passage (732) and transferred to the inlet (510) of the housing (500). At this time, a connecting pipe (760) may be provided to connect the other side of the gas passage (732) from which the gas is discharged and the inlet (510) of the housing (500). The low temperature part (730) is cooled by the gas flowing through the gas passage (732) and is cooled by dissipating heat to a fifth heat dissipation fin (734) formed in the low temperature part (730). The gas transferred to the inlet (510) flows into the housing (500) and is transferred to the burner (600) while being mixed with air along the mixing passage (50). One side of the nozzle (600) through which the gas is burned faces the combustion hole (520), so that the gas transferred to the nozzle (600) can be mixed with the air flowing in from the combustion hole (520) and completely burned.

[0074] A thermoelectric gas burner 4 according to a fourth embodiment of the present invention will now be described. Fig. 4 is a cross-sectional view showing a thermoelectric gas burner according to the fourth embodiment of the present invention.

[0075] Referring to FIG. 4, the thermoelectric power-generating gas burner (4) mainly includes a housing (800), a thermoelectric module (900), and an inlet pipe (1000).

[0076] First, the housing (800) will be described. The housing (800) may have an inlet hole (810), a combustion hole (820), and a seventh heat dissipation fin (830). The inlet hole (810) may be formed on one side (lower side as viewed in the drawing) of the housing (800), and an inlet pipe (1000) described below may be inserted into the inlet hole (810). The combustion hole (820) may be formed on the other side (upper side as viewed in the drawing) of the housing (800), and air may be introduced into the housing (800) through the combustion hole (820). The air introduced into the combustion hole (820) may be mixed with gas and combusted in a high temperature portion (920) of the thermoelectric module described below.

[0077] Meanwhile, a plurality of seventh heat dissipation fins (830) may be formed on the outer circumferential surface of the housing (800).

[0078] Next, the thermoelectric module 900 will be described. The thermoelectric module 900 includes a thermoelectric element 910, a high temperature section 920, and a low temperature section 930. The thermoelectric element 910 may be a conventional thermoelectric element using the Seebeck effect. The high temperature section 920 may be configured to burn gas and may be in contact with one side (upper side as viewed in the figure) of the thermoelectric element 910 to transfer heat to the thermoelectric element 910. The low temperature section 930 may be in contact with the other side (lower side as viewed in the figure) of the thermoelectric element 910 to cool the thermoelectric element 910, and the low temperature section 930 may be formed with an inlet passage 932 through which gas flows in and an outlet passage 934 through which gas is discharged.

[0079] In addition, a plurality of sixth heat dissipation fins (936) may be formed on one side of the low temperature portion (930) facing the inlet hole (810), i.e., on the side opposite to the side of the low temperature portion (930) that contacts the thermoelectric element (910). In this case, the sixth heat dissipation fins (936) of the low temperature portion (930) may be configured so that at least a portion of the sixth heat dissipation fins (936) contacts the housing (800).

[0080] Such a thermoelectric module (900) may be disposed inside the housing such that the high temperature portion (920) faces the combustion hole (820) of the housing (800) and the low temperature portion (930) faces the inlet hole (810) of the housing (800).

[0081] Also, as shown in FIG. 4, the thermoelectric module (900) may be disposed inside the housing (800) such that a first space (60) is formed between the outer peripheral surface of the thermoelectric module (900) and the housing (800).

[0082] Next, the inlet pipe (1000) will be described. The inlet pipe (1000) may be formed of a pipe having a plurality of holes (1010) formed therein so that the gas flows in and communicates with the outside, or may be connected to the inlet passage (932) of the low temperature section (930) from the outside of the housing (800) through the inlet holes (810).

[0083] Next, the operation of the thermoelectric power generating gas burner (4) will be described.

[0084] The gas is transferred along the inlet pipe (1000) to the inlet flow passage (932) of the low temperature section (930). At this time, air flows into the inlet pipe (1000) through a plurality of holes (1010) formed in the inlet pipe (1000), so that the gas flowing through the inlet pipe (1000) can be mixed with the air.

[0085] The gas transferred to the inlet passage (932) flows into the inlet passage (932) and is discharged to the discharge passage (934) to cool the low temperature section (930). The gas discharged to the discharge passage (934) is accommodated in the first space (60) and moves to the high temperature section (920) where it can be burned. One side of the high temperature section (920) where the gas is burned faces the combustion hole (820), so that the gas transferred to the high temperature section (920) can be mixed with the air flowing in from the combustion hole (820) and completely burned.

[0086] On the other hand, since the sixth heat dissipation fin (936) of the low temperature section (930) is at least partially in contact with the housing (800), the heat of the low temperature section (930) is transferred to the housing (800) and can be dissipated by the seventh heat dissipation fin (830) formed on the housing (800).

[0087] FIG. 5 is a cross-sectional view showing a schematic overall structure of a thermoelectric power-generating gas burner according to the present invention.

[0088] As shown in FIG. 5, the thermoelectric power-generating gas burner of the present invention may be configured such that gas discharged from a gas cylinder (6) provided inside the main body (5) flows into the inside of a housing (9) in which a thermoelectric module (7) is provided.

[0089] In addition, the gas that flows into the housing (9) cools the low-temperature portion of the thermoelectric module (7), and is then transferred to the burner or the high-temperature portion of the thermoelectric module (7), where it is burned while generating a flame (11), thereby heating the high-temperature portion of the thermoelectric module (7).

[0090] However, it is not limited thereto, and it goes without saying that the thermoelectric gas burner does not need to be provided with a separate body (5) surrounding the gas cylinder (6) and the housing (9).

[0091] In this way, the thermoelectric power generating gas burner according to the present invention does not require a separate fan or cooling device for cooling the low-temperature part of the thermoelectric module, as the gas discharged from the gas cylinder comes into direct contact with and cools the low-temperature part of the thermoelectric module, and therefore the thermoelectric power generating gas burner can be manufactured to be small and lightweight.

[0092] In addition, since the low-temperature portion of the thermoelectric module is configured to come into direct contact with a large amount of gas per unit time, or gas is configured to pass through the inside of the low-temperature portion of the thermoelectric module, the temperature difference between the high-temperature and low-temperature portions of the thermoelectric module becomes large, and a larger amount of electricity can be produced.

[0093] The above description of the present invention is for illustrative purposes only, and a person having ordinary skill in the art to which the present invention pertains will understand that the present invention can be easily modified into other specific forms without changing the technical idea or essential features of the present invention. Therefore, the above-described embodiments should be understood as illustrative in all respects and not limiting. For example, each component described as a single type may be implemented in a distributed form, and similarly, each component described as a distributed type may be implemented in a combined form.

[0094] The scope of the present invention is indicated by the claims set forth below rather than by the above detailed description, and all modifications and variations that fall within the meaning and scope of the claims and their equivalent concepts should be interpreted as being included within the scope of the present invention. [Industrial Applicability]
