Abstract
Description
- The present invention relates to a heat unit and a heat module including the same, and more particularly, to a heat unit configured to generate heat when a current is applied thereto and a heat module including the same.
- Recently, heating yarn which generates heat when a current is applied thereto has been manufactured.
- The heating yarn is a fiber impregnated with carbon (hereinafter referred to as 'carbon-impregnated fiber') and generates heat by generating resistance when electricity is applied thereto.
- Heating fabric woven from the carbon-impregnated fiber serving as heating yarn may be heated to a desired temperature within a short time period due to a high electric resistance property of the heating yarn, does not generate electromagnetic waves unlike existing electric mats, and has a constant temperature characteristic in which a temperature thereof is not increased any more when the heating fabric reaches a certain temperature. Accordingly, power consumption may be minimized, a user may be prevented from being burned, and thus much attention has been paid to the heating fabric as a healthy product.
- However, in the case of the carbon-impregnated fiber, it is very difficult to uniformize a distribution of carbon when fiber is impregnated with carbon, and a deviation in energy efficiency is very high according to carbon mixing and dispersion ratios.
- As the distance between the carbon-impregnated fiber and a current source increases, the amount of generated heat becomes reduced and thus heat is not uniformly generated.
- Furthermore, since carbon is a resistor, a large amount of power is needed to generate heat from the whole carbon-impregnated fiber.
- To address the above-described problems, the present invention is directed to uniformizing a distribution of carbon, uniformly generating heat, and generating a large amount of heat from a small amount of power.
- However, the present invention is not limited thereto, and additional aspects will be apparent to those of ordinary skill in the art from the present disclosure and the appended drawings.
- One aspect of the present invention provides a heat unit including a conductor configured to cause electricity to flow therethrough in a lengthwise direction, and a heating element configured to generate heat from the electricity transferred thereto from the conductor. The heating element surrounds the conductor in the lengthwise direction to prevent occurrence of electric shock.
- Another aspect of the present invention provides a heat module including the heat unit, an insulator configured to insulate the heat unit, and a fixing part configured to fix the heat unit at a certain location on the insulator.
- According to a heat unit and a heat module including the same according to an embodiment of the present invention, a distribution of carbon can be uniformized, heat can be uniformly generated, and a large amount of heat can be generated from a small amount of power.
- The effects of the present invention are not, however, limited thereto, and additional effects will become apparent and more readily appreciated by those of ordinary skill in the art to which the present invention belongs from the following description and the appended drawings.

FIGS. 1 and 2 , aheat unit 10 according to an embodiment of the present invention may be configured to generate heat by resistance when electricity is applied thereto. - That is, the
heat unit 10 may be configured to generate heat by converting electric energy into heat energy. - Here, the
heat unit 10 may include aconductor 100 configured such that electricity flows therethrough in a lengthwise direction, and aheating element 200 configured to generate heat from the electricity transferred thereto from theconductor 100. - For example, the
conductor 100 may have a cylindrical shape extending lengthily in the lengthwise direction. - For example, an electric current may flow through the
conductor 100 in the lengthwise direction when a positive (+) electrode and a negative (-) electrode are connected to opposite ends thereof. - For example, the
conductor 100 may be a metal or a composite formed of one or more metals selected from among aluminum, silver, bronze, iron, and copper. - For example, the
heating element 200 may be a resistor having a certain resistance. - That is, the
heating element 200 may be a resistor which resists an electric current transferred from theconductor 100 and may generate heat using electric resistance. - For example, the
heating element 200 may include a heating agent generating heat by electricity, and a softening agent increasing moldability. - The heating agent may be a resistor which generates heat through electric resistance, and may be, for example, carbon.
- The softening agent is configured to increase moldability, and may be, for example, polyethylene.
- For example, the softening agent may be melted at a certain temperature and fused, mixed, or polymerized with the heating agent. When cooled to normal temperature, the softening agent may have a certain degree of strength and thus may be prevented from being broken even when a certain tensile force is applied thereto and may be bent in various forms by an external force.
- That is, the
heating element 200 may generate heat when an electric current is applied thereto due to the heating agent which is a resistor, and may be bent or deformed into various forms without being broken due to the softening agent even when a certain external force is applied thereto. - Similarly, the
conductor 100 may be bent or deformed into various forms when a certain external force is applied thereto. - Here, as illustrated in
FIGS. 1 and 2 , theheating element 200 may surround theconductor 100 in the lengthwise direction. - For example, the
heating element 200 may have a long pipe shape having a hollow formed in the lengthwise direction, and theconductor 100 is inserted into the hollow of theheating element 200 to be surrounded by theheating element 200. - Since an external side of the
conductor 100 is surrounded by theheating element 200 in the lengthwise direction, a user may be prevented from being shocked by an electric current flowing through theconductor 100. - Furthermore, since the
heating element 200 is in contact with an external surface of theconductor 100 in the lengthwise direction, theheating element 200 may generate heat uniformly in the lengthwise direction in which theheating element 200 is in contact with theconductor 100. - That is, heat is not generated from only a portion of the
heating element 200 in the lengthwise direction but may be uniformly generated from theheating element 200 in the lengthwise direction. - Accordingly, an effect of generating a large amount of heat from even a small amount of power may be achieved.
- For example, the
heat unit 10 according to an embodiment of the present invention may further include atemperature sensor part 300 configured to sense a temperature of generated heat. - For example, the
temperature sensor part 300 may be configured to sense a temperature change caused by heat generated by theheating element 200. - For example, the
temperature sensor part 300 may have a long pillar shape in the lengthwise direction. - For example, the
temperature sensor part 300 may be a thermocouple. - However, the
temperature sensor part 300 is not limited to the thermocouple, and may be variously changed by those of ordinary skill in the art, provided that a temperature changed by heat generated by theheating element 200 can be sensed. - For example, the
temperature sensor part 300 may be arranged adjacent to theconductor 100 surrounded by theheating element 200. - In more detail, the
heating element 200 may form another hollow in the lengthwise direction, and thetemperature sensor part 300 may be inserted into the other hollow of theheating element 200 to be surrounded by theheating element 200. - That is, the
heating element 200 may protect thetemperature sensor part 300 from an external environment by surrounding thetemperature sensor part 300 in the lengthwise direction. - The
temperature sensor part 300 may be inserted into theheating element 200 in the lengthwise direction to sense a temperature of heat generated by theheating element 200 in the lengthwise direction. - An outer side surface of the
temperature sensor part 300 may be in contact with theheating element 200 and thus may receive heat generated from theheating element 200 and sense the temperature of theheat element 200. - Thus, the
temperature sensor part 300 may not sense a temperature of heat generated from only a portion of theheating element 200 in the lengthwise direction but may sense a temperature of heat generated from thewhole heating element 200 in the lengthwise direction. - For example, the
temperature sensor part 300 may be arranged inside theheating element 200 to be spaced apart from theconductor 100. - The
heating element 200 may be formed such that a plurality of hollows are spaced apart from each other, and thus, theconductor 100 and thetemperature sensor part 300 inserted into the plurality of hollows may be located spaced apart from each other while being surrounded by theheating element 200. - As a result, the
heating element 200 may prevent an electric current flowing through theconductor 100 from directly flowing to thetemperature sensor part 300. - A
heat module 1 according to another embodiment of the present invention will be described in detail below. - As illustrated in
FIG. 3 , theheat module 1 may include theheat unit 10, aninsulator 20 configured to insulate theheat unit 10, and a fixingpart 30 configured to fix theheat unit 10 at a certain location on theinsulator 20. - The
insulator 20 may be configured to insulate theheat unit 10. - For example, when the
heating element 200 of theheat unit 10 partially peels off or a thickness thereof decreases, an electric current flowing through theconductor 100 may flow to a user and thus the user may be shocked by the current. - To prevent this problem, the
insulator 20 may cover at least one side of theheat unit 10 to insulate theheat unit 10. - For example, the
insulator 20 may be a nonconductor, e.g., a nonmetal, plastic, fiber, or the like. - The fixing
part 30 may be configured to restrict theheat unit 10 to be fixed at a certain location with respect to theinsulator 20. - The
heat unit 10 may be arranged and fixed at a certain location at a side of theinsulator 20 by the fixingpart 30. - Here, the
insulator 20 may include a through-space S1 configured such that theheat unit 10 is prevented from passing therethrough and the fixingpart 30 is allowed to pass therethrough. - The through-space S1 may have a width less than that of the
heat unit 10 so that theheat unit 10 located at one side of theinsulator 20 cannot pass through another side of theinsulator 20. - Here, the fixing
part 30 may include a fixingexposure part 31 located at the other side of theinsulator 20, a fixingpass part 32 extending from one end of the fixingexposure part 31 to pass through the through-space S1, and a fixing and surroundingpart 33 extending from the fixingpass part 32 to surround theheat unit 10 located at the one side of theinsulator 20. - The fixing
exposure part 31 may be supported on the other side of theinsulator 20. The fixingpass part 32 may extend from the fixingexposure part 31 and be located in the through-space S1. The fixing and surroundingpart 33 may extend from the fixingpass part 32 to surround theheat unit 10, thereby fixing theheat unit 10 at a certain location. - In
FIG. 3 , if an external force which moves theheat unit 10 downward is applied to theheat unit 10, the external force may be transferred to the fixing and surroundingpart 33 from theheat unit 10. The external force transferred to the fixing and surroundingpart 33 may be transferred to the fixingexposure part 31 via the fixingpass part 32, and the fixingexposure part 31 may transfer the external force to theinsulator 20 while being supported at the other side of theinsulator 20. - Accordingly, the
heat unit 10 may be fixed at the one side of theinsulator 20 by the fixing and surroundingpart 33, the fixingpass part 32, and the fixingexposure part 31 even when the external force which moves theheat unit 10 downward is applied to theheat unit 10. - Here, the fixing
part 30 may further include a fixingextension part 34 extending from another end of the fixingexposure part 31. - The fixing
pass part 32 may extend from the one end of the fixingexposure part 31, and the fixingextension part 34 may extend from the other end of the fixingexposure part 31. - Here, the
insulator 20 may further include a pass-space S2 configured to allow the fixingextension part 34 to pass therethrough. - The pass-space S2 may be formed spaced apart from the through-space S1.
- Here, the fixing
extension part 34 may extend from the other end of the fixingexposure part 31, pass through the pass-space S2, and be exposed to the one side of theinsulator 20 at which theheat unit 10 is disposed. - The fixing
extension part 34 exposed to the one side of theinsulator 20 may be directly or indirectly supported on the one side of theinsulator 20. - In
FIG. 3 , if the fixingexposure part 31 is pulled upward by an external force, the external force applied to the fixingexposure part 31 is transferred to the fixing and surroundingpart 33 via the fixingpass part 32. The external force applied to the fixing and surroundingpart 33 may be transferred to theheat unit 10 and thus theheat unit 10 may be pressurized upward by the external force. - In this case, the
heat unit 10 may be pressurized between the fixing and surroundingpart 33 and theinsulator 20 and be thus broken, or theheating element 200 of theheat unit 10 may peel off. - To solve this problem, the external force applied to the fixing
exposure part 31 in an upward direction may be transferred to the fixingextension part 34 and be then directly or indirectly transferred to the one side of theinsulator 20 by the fixingextension part 34, thereby dispersing or decreasing the external force applied to theheat unit 10. - Accordingly, the
heat unit 10 may be stably located and fixed at the one side of theinsulator 20 without being broken by the external force applied in the upward direction by the fixingextension part 34. - For example, the fixing
extension part 34 may be directly or indirectly fixed to theinsulator 20. - Thus, the external force applied to the fixing
extension part 34 may be directly or indirectly transferred to theinsulator 20. -
FIG. 4 is a schematic block diagram of theheat module 1. - As illustrated in
FIG. 4 , theheat module 1 may further include adisplay unit 40 configured to display certain information to a user, aninput unit 50 configured to receive input information from the user, and acontroller 60 configured to control thedisplay unit 40, theinput unit 50, theconductor 100, and thetemperature sensor part 300. - For example, the
controller 60 may adjust intensity of an electric current applied to theconductor 100 according to the input information input to theinput unit 50. - Furthermore, the
controller 60 may calculate a temperature sensed by thetemperature sensor part 300, and adjust the intensity of the electric current applied to theconductor 100 according to the temperature sensed by thetemperature sensor part 300. - For example, when the temperature sensed by the
temperature sensor part 300 is higher than a reference temperature, thecontroller 60 may decrease the intensity of the electric current applied to theconductor 100 or may not supply an electric current to theconductor 100. - In contrast, when the temperature sensed by the
temperature sensor part 300 is lower than the reference temperature, thecontroller 60 may increase the intensity of the electric current applied to theconductor 100. - As a result, the
controller 60 may prevent the occurrence of fire caused by high-temperature heat generated by theheating element 200, and may maintain an appropriate temperature which a user wants. - A
heat unit 10A according to another embodiment of the present invention will be described in detail with reference toFIGS. 5 to 10 below. - As illustrated in
FIGS. 5 to 8 , theheat unit 10A according to another embodiment of the present invention may be configured to generate heat through resistance when electricity is applied thereto. - That is, the
heat unit 10A may be configured to generate heat by converting electric energy into heat energy. - Here, the
heat unit 10A according to another embodiment of the present invention may include apositive electrode conductor 1000 connected to a positive electrode and extending in a lengthwise direction, anegative electrode conductor 2000 connected to a negative electrode and extending in the lengthwise direction, and aheating element 3000 configured to generate heat from a flow of electrons generated by thepositive electrode conductor 1000 and thenegative electrode conductor 2000. - For example, the
positive electrode conductor 1000 and thenegative electrode conductor 2000 may be components of theconductor 100 of theheat unit 10 described above. - For example, the
positive electrode conductor 1000 and thenegative electrode conductor 2000 may each have a cylindrical shape extending lengthily in the lengthwise direction. - For example, one end of the
positive electrode conductor 1000 may be connected to a positive electrode of a controller (not shown) generating a flow of electrons, and one end of thenegative electrode conductor 2000 may be connected to a negative electrode of the controller. - For example, each of the
positive electrode conductor 1000 and thenegative electrode conductor 2000 may be a metal or a composite formed of one or more metals selected from among aluminum, silver, bronze, iron, and copper. - For example, the
heating element 3000 may be a resistor having a certain degree of resistance. - That is, the
heating element 3000 may be a resistor resisting an electric current and may generate heat by resisting a flow of electrons. - For example, the
heating element 3000 may include a heating agent generating heat from electricity, and a softening agent increasing moldability. - The heating agent may be a resistor configured to generate heat through electric resistance, and may be, for example, carbon.
- The softening agent is configured to increase moldability and may be, for example, polyethylene.
- For example, the softening agent may be melted at a certain temperature and fused, mixed, or polymerized with the heating agent. When cooled to normal temperature, the softening agent may have a certain degree of strength and thus may be prevented from being broken even when a certain tensile force is applied thereto and may be bent in various forms by an external force.
- That is, the
heating element 3000 may generate heat when an electric current is applied thereto due to the heating agent which is a resistor, and may be bent or deformed into various forms without being broken due to the softening agent even when a certain external force is applied thereto. - Similarly, the
positive electrode conductor 1000 and thenegative electrode conductor 2000 may be bent or deformed into various forms when a certain external force is applied thereto. - Here, the
heating element 3000 may surround thepositive electrode conductor 1000 and thenegative electrode conductor 2000 in the lengthwise direction to prevent the occurrence of electrical shock. - For example, the
heating element 3000 may have a long pipe shape having a hollow formed in the lengthwise direction. Each of thepositive electrode conductor 1000 and thenegative electrode conductor 2000 may be inserted into the hollow of theheating element 3000 to be surrounded by theheating element 3000. - Alternatively, the
heating element 3000 may be formed by extrusion molding on outer surfaces of thepositive electrode conductor 1000 and thenegative electrode conductor 2000. - The
heating element 3000 surrounds outer sides of thepositive electrode conductor 1000 and thenegative electrode conductor 2000 in the lengthwise direction and may thus prevent a user from getting shocked by an electric current flowing through thepositive electrode conductor 1000 and thenegative electrode conductor 2000. - Here, the
positive electrode conductor 1000 and thenegative electrode conductor 2000 may not be connected to each other but may be arranged inside theheating element 3000 to be spaced apart from each other. - That is, the
positive electrode conductor 1000 may extend from the positive electrode of the controller in the lengthwise direction, and may not be in contact with thenegative electrode conductor 2000 inside theheating element 3000. - Similarly, the
negative electrode conductor 2000 may extend from the negative electrode of the controller in the lengthwise direction, and may not be in contact with thepositive electrode conductor 1000 inside theheating element 3000. - Accordingly, electrons flowing through the
negative electrode conductor 2000 may move to thepositive electrode conductor 1000 from thenegative electrode conductor 2000 via theheating element 3000 and thus implement heat generation from theheating element 3000. - That is, the electrons flowing through the
negative electrode conductor 2000 cannot directly move to thepositive electrode conductor 1000 but may move to thepositive electrode conductor 1000 via theheating element 3000 due to a voltage between thenegative electrode conductor 2000 and thepositive electrode conductor 1000. - Accordingly, even if a low voltage is applied between the
positive electrode conductor 1000 and thenegative electrode conductor 2000, all electrons move from thenegative electrode conductor 2000 to thepositive electrode conductor 1000 via theheating element 3000 and thus the efficiency of generating heat from theheating element 3000 may be maximized. - Here, as illustrated in
FIGS. 6 and7 , for example, theheat unit 10A according to another embodiment of the present invention may further include a negativeelectrode guide part 4200 connected to thenegative electrode conductor 2000 and configured to guide a direction of electrons flowing from thenegative electrode conductor 2000 to thepositive electrode conductor 1000. - For example, a plurality of negative
electrode guide parts 4200 may be formed on thenegative electrode conductor 2000 in the lengthwise direction to be spaced apart from each other. - For example, the negative
electrode guide parts 4200 may be fixed to thenegative electrode conductor 2000 while surrounding thenegative electrode conductor 2000. - Here, the negative
electrode guide parts 4200 may be conductors allowing electrons to flow therethrough. - That is, the negative
electrode guide parts 4200 may receive electrons from thenegative electrode conductor 2000 and guide the electrons to flow to thepositive electrode conductor 1000. - More specifically, distances between the negative
electrode guide parts 4200 and thepositive electrode conductor 1000 in regions of thenegative electrode conductor 2000 on which the negativeelectrode guide parts 4200 are disposed may be less than a distance between thenegative electrode conductor 2000 and thepositive electrode conductor 1000. - As a result, an amount of electrons flowing toward the
positive electrode conductor 1000 via theheating element 3000 in the regions of thenegative electrode conductor 2000 on which the negativeelectrode guide parts 4200 are disposed may be greater than that of electrons flowing toward thepositive electrode conductor 1000 via theheating element 3000 in the other regions of thenegative electrode conductor 2000 on which the negativeelectrode guide parts 4200 are not disposed. - Accordingly, the negative
electrode guide parts 4200 may be arranged at predetermined locations on thenegative electrode conductor 2000 if necessary to guide electrons to flow from thenegative electrode conductor 2000 to thepositive electrode conductor 1000 via theheating element 3000. - Furthermore, for example, the plurality of negative
electrode guide parts 4200 are fixed to thenegative electrode conductor 2000 in the lengthwise direction to be spaced apart from each other and thus a fixing force between thenegative electrode conductor 2000 and theheating element 3000 may be maximized. - Here, as illustrated in
FIGS. 6 and7 , for example, theheat unit 10A according to another embodiment of the present invention may further include a positiveelectrode guide part 4100 connected to thepositive electrode conductor 1000 and configured to guide a direction of electrons flowing from thenegative electrode conductor 2000 toward thepositive electrode conductor 1000. - For example, a plurality of positive
electrode guide parts 4100 may be formed on thepositive electrode conductor 1000 in the lengthwise direction to be spaced apart from each other. - For example, the positive
electrode guide parts 4100 may be fixed to thepositive electrode conductor 1000 while surrounding thepositive electrode conductor 1000. - Here, the positive
electrode guide parts 4100 may be conductors allowing electrons to flow therethrough. - That is, the positive
electrode guide parts 4100 may receive electrons flowing from thenegative electrode conductor 2000 to theheating element 3000 and guide the electrons to flow to thepositive electrode conductor 1000. - More specifically, distances between the positive
electrode guide parts 4100 and thenegative electrode conductor 2000 in regions of thepositive electrode conductor 1000 on which the positiveelectrode guide parts 4100 are disposed may be less than the distance between thenegative electrode conductor 2000 and thepositive electrode conductor 1000. - Thus, an amount of electrons flowing from the regions of the
negative electrode conductor 2000 on which the positiveelectrode guide parts 4100 are located toward thepositive electrode conductor 1000 via theheating element 3000 may be greater than that of electrons flowing from the other regions of thenegative electrode conductor 2000 on which the positiveelectrode guide parts 4100 are not located toward thepositive electrode conductor 1000 via theheating element 3000. - Accordingly, the positive
electrode guide parts 4100 may be arranged on predetermined locations on thepositive electrode conductor 1000 if necessary to guide electrons to flow from thenegative electrode conductor 2000 toward thepositive electrode conductor 1000 via theheating element 3000. - Furthermore, for example, the plurality of positive
electrode guide parts 4100 may be fixed to thenegative electrode conductor 2000 in the lengthwise direction to be spaced apart from each other, thereby maximizing a fixing force between thepositive electrode conductor 1000 and theheating element 3000. - Here, for example, the negative
electrode guide parts 4200 and the positiveelectrode guide parts 4100 may not overlap each other in a widthwise direction perpendicular to the lengthwise direction. - If the negative
electrode guide parts 4200 and the positiveelectrode guide parts 4100 are arranged at a location at which they overlap each other in the widthwise direction, separation distances between the negativeelectrode guide parts 4200 and the positiveelectrode guide parts 4100 are relatively small and thus electrons flowing toward thepositive electrode conductor 1000 from thenegative electrode conductor 2000 via theheating element 3000 may be concentrated in a region in which the positiveelectrode guide parts 4100 and the negativeelectrode guide parts 4200 overlap each other. - Accordingly, the negative
electrode guide parts 4200 and the positiveelectrode guide parts 4100 may be arranged not to overlap each other in the widthwise direction to uniformly generate heat from theheating element 3000 in the lengthwise direction. - Here, for example, as illustrated in
FIG. 4 , the negativeelectrode guide parts 4200 and the positiveelectrode guide parts 4100 may be nonconductors which do not allow electrons to flow therethrough. - When the negative
electrode guide parts 4200 are nonconductors, the negativeelectrode guide parts 4200 may guide electrons flowing through theheating element 3000, which is close to thenegative electrode conductor 2000, in the lengthwise direction to flow toward thepositive electrode conductor 1000. - When the positive
electrode guide parts 4100 are nonconductors, the positiveelectrode guide parts 4100 may prevent electrons flowing through theheating element 3000 from being concentrated on a specific region of thepositive electrode conductor 1000 and may disperse electrons flowing from theheating element 3000 to thepositive electrode conductor 1000. - Furthermore, fixing forces between the
positive electrode conductor 1000 and theheating element 3000 and between thenegative electrode conductor 2000 and theheating element 3000 may be increased. - A through-hole may be formed in the positive
electrode guide part 4100 into which thepositive electrode conductor 1000 may be inserted to pass therethrough, and a through-hole may be formed in the negativeelectrode guide part 4200 into which thenegative electrode conductor 2000 may be inserted to pass therethrough. - The positive
electrode guide part 4100 and the negativeelectrode guide part 4200 may each have a plate shape or may be respectively compressed onto thepositive electrode conductor 1000 and thenegative electrode conductor 2000 to be fixed onto thepositive electrode conductor 1000 and thenegative electrode conductor 2000. - Here, for example, as illustrated in
FIGS. 7 and 8 , a thickness D2 of a portion of thenegative electrode conductor 2000 which is in contact with the negativeelectrode guide part 4200 may be less than a thickness D1 of the other portions of thenegative electrode conductor 2000 which are not in contact with the negativeelectrode guide part 4200. - That is, an inwardly recessed step D may be formed at the portion of the
negative electrode conductor 2000 which is in contact with the negativeelectrode guide part 4200. - Thus, an area of the negative
electrode guide part 4200 which is in contact with thenegative electrode conductor 2000 may be increased to more firmly fix the negativeelectrode guide part 4200 to thenegative electrode conductor 2000. - Similarly, a thickness of a portion of the
positive electrode conductor 1000 which is in contact with the positiveelectrode guide part 4100 may be less than a thickness of the other portions of thepositive electrode conductor 1000 which are not in contact with the positiveelectrode guide part 4100. - A negative
electrode guide part 4200A and a positiveelectrode guide part 4100A which are another embodiment of the negativeelectrode guide part 4200 and the positiveelectrode guide part 4100 will be described with reference toFIGS. 9 and 10 below. - Parts of the negative
electrode guide part 4200A and the positiveelectrode guide part 4100A which are the same as those of the negativeelectrode guide part 4200 and the positiveelectrode guide part 4100 described above in terms of technical features thereof will not be described again here. - For example, the negative
electrode guide part 4200A may include a negativeelectrode contact part 4210A which is in contact with and connected to thenegative electrode conductor 2000, and a negativeelectrode extension part 4220A extending from the negativeelectrode contact part 4210A. - Here, for example, the negative
electrode extension part 4220A may extend from the negativeelectrode contact part 4210A toward thepositive electrode conductor 1000. - The negative
electrode extension part 4220A may be arranged toward thepositive electrode conductor 1000 if necessary to reduce a separation distance between negativeelectrode extension part 4220A and thepositive electrode conductor 1000, so that a flow of electrons moving through theheating element 3000 may be more actively guided using the negativeelectrode guide part 4200A. - Similarly, for example, the positive
electrode guide part 4100A may include a positiveelectrode contact part 4110A which is in contact with and connected to thepositive electrode conductor 1000, and a positiveelectrode extension part 4120A extending from the positiveelectrode contact part 4110A. - Here, for example, the positive
electrode extension part 4120A may extend from the positiveelectrode contact part 4110A toward thenegative electrode conductor 2000. - Thus, the positive
electrode extension part 4120A may be arranged toward thenegative electrode conductor 2000 to reduce a separation distance between the positiveelectrode extension part 4120A and thenegative electrode conductor 2000. - Furthermore, the positive
electrode extension part 4120A and the negativeelectrode extension part 4220A may be arranged not to overlap each other in the widthwise direction. - As described above, the
heat unit 10A according to another embodiment of the present invention may generate high-temperature heat even from a relatively low voltage, and may further guide a flow of electrons flowing through theheating element 3000 to uniformly generate heat from thewhole heating element 3000. - The
heat units temperature sensor part 300 which is a component of theheat unit 10 described above is applicable to theheat unit 10A. - Furthermore, it will be apparent that the
heat module 1 may be embodied as including theheat unit 10A. - That is, for example, it will be apparent that the
heat module 1 may be embodied by, for example, coupling theheat unit 10A to theinsulator 20 and the fixingpart 30. - While the structure and features of the present invention have been described above with respect to embodiments thereof, the present invention is not limited thereto and it will be apparent to those of ordinary skill in the art that various changes or modifications may be made in the present invention without departing from the idea and scope of the present invention. Accordingly, such changes or modifications should be understood as falling within the scope of the invention defined in the claims appended herein.
