Description
Technical Field
The present invention relates to a heating element, and more particularly, to a heating element having a fusing function and a heating unit including the same.
Background
Heaters using common nichrome wire have a concern of ignition when overheated. Accordingly, the electric vehicle is equipped with a heating unit using the PTC element for heating.
However, the heating unit using the PTC element as the heat generating element has a limitation in enlarging the size of the PTC element, and thus cannot obtain a large amount of heat generation.
In addition, in the heating unit using the PTC element, since the conductive carbon mixture as the conductor is bonded only to a part of the heat generating surface of the PTC element, there is a problem that temperature distribution is not uniform depending on the conductor portion and the temperature transmitted to the heat sink is different.
Accordingly, development of a heating element and a heating unit that have a uniform temperature distribution and can obtain a large amount of heat generation has been demanded.
In addition, since the heating unit using the PTC element uses a method of heating air in contact with the heat sink by transferring heat generated in the heat generating element to the heat sink, thermal resistance is generated in the process of transferring heat from the heat generating element to the heat sink, and there is a structural problem of greatly reducing the heat density.
Disclosure of Invention
(problem to be solved)
The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a heating element having a fusing function and a heating unit including the same, which can reduce thermal resistance to increase heat density and prevent ignition due to overheating that may occur during heat generation.
Another object of the present invention is to provide a heat generating element having a fusing function and a heating unit including the same, which can obtain a uniform temperature distribution and can secure a large amount of heat generation.
(means for solving the problems)
In order to achieve the above object, the present invention provides a heating element having a fusing function, comprising: a plurality of heat sources that generate heat when current is applied; a fusing member physically connected at both end portions to two heat sources arranged at a distance from each other to connect the two heat sources in series, and fused at a set temperature or higher to cut off electrical connection of the two heat sources; and an insulating member wrapping the plurality of heat sources and the fusing member.
In addition, the heat source may be a plate-shaped conductive member having a predetermined area. As an example, the heat source may be a plate-shaped gasket including at least one of an amorphous ribbon sheet, a metal sheet, an iron-chromium-aluminum alloy, and an iron-carbon alloy.
In addition, the fusing member may be a plate-shaped conductive member having a predetermined area. As an example, the fusing member may be formed of lead, tin, zinc, cadmium, copper, and one or more metal materials combining them with each other.
Both end portions of the fusing member may be connected to upper or lower surfaces of two heat sources disposed at a distance from each other.
In addition, the fusing part may include: first fusing members, both end portions of which are connected to the upper surfaces of two heat sources arranged at a distance from each other; and a second fusing member having both end portions connected to lower surfaces of the two heat sources arranged at a distance from each other. At this time, at least a part of the first fuse member and the second fuse member may be contacted between the two first heat sources and the second heat source.
The insulating member may be a thin film member having insulating properties.
In addition, the heating element may be bent a plurality of times along a longitudinal direction to form a flow passage through which a fluid passes. In this case, the heat generating element may be formed by bending a plurality of times to alternately form crests and troughs along the longitudinal direction, and the flow path may be a space formed by the crests and troughs.
In addition, the heating element may further include a metal sheet attached to one surface of the insulating member by an adhesive layer.
The present invention provides a heating unit including the above-described heating element having a fusing function.
(Effect of the invention)
In the present invention, since the heat generating element itself has a fusing function, the fusing function is performed when a plurality of heat sources generating heat when power is applied generate heat at a high temperature equal to or higher than a predetermined temperature, and the current flow is cut off, thereby preventing an ignition phenomenon due to overheating. Accordingly, even if a controller failure occurs, the heater itself can be protected.
In addition, the heating element of the present invention is realized in a surface shape, and further, the heat resistance is reduced, the heat generation efficiency can be improved, and the reactivity can be improved.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those having ordinary knowledge in the art to which the present invention pertains can easily carry out the embodiments. The present invention can be realized in various forms, and is not limited to the embodiments described herein. In order to clearly explain the present invention, portions that are not related to the description are omitted in the drawings, and the same reference numerals are given to the same or similar constituent elements throughout the specification.
As shown in fig. 1 to 7, a heating element 100, 200 with a fusing function according to an embodiment of the present invention includes: a plurality of heat sources 110, fusing members 120, 120', 120 ″, and an insulating member 130.
The plurality of heat sources 110 generate heat when power is applied, and thus may generate heat. As shown in fig. 4 to 7, the plurality of heat sources 110 may be disposed at intervals along the longitudinal direction of the heat generating elements 100 and 200, and may be electrically connected to each other through the fusing members 120, 120', and 120 ″.
That is, the plurality of heat sources 110 may be disposed at intervals along the longitudinal direction of the heat generating elements 100 and 200, and two heat sources 110 disposed at intervals along the longitudinal direction may be connected in series by the fuse members 120, 120', and 120 ″.
Accordingly, when power is applied from the outside, the plurality of heat sources 110 are electrically connected to each other through the fusing members 120, 120', and 120 ″, and thus can generate heat.
At this time, the plurality of heat sources 110 may be configured in a plate shape having a predetermined area. That is, the heat source 110 may be a plate-shaped conductive member that generates heat when power is applied.
As a non-limiting example, the heat source 110 may use amorphous ribbon sheets. Here, the amorphous ribbon may be a ribbon including at least one of an amorphous alloy and a nanocrystalline alloy. In addition, the heat source 110 may be a metal sheet having a plate shape with a predetermined area, and aluminum, copper, or the like may be used as the metal sheet.
Further, the heat source 110 may be a plate-shaped conductive member including at least one of an iron-chromium-aluminum alloy and an iron-carbon alloy to prevent crystallization due to repeated exposure to thermal fatigue.
However, the material of the heat source 110 is not limited thereto, and the linear conductive members arranged in a predetermined pattern may also realize a plate shape or a face shape, and all known heat sources used as heaters may be applied as long as the heat source can realize a face shape or a plate shape.
Here, the plurality of heat sources 110 constituting the heat generating elements 100 and 200 may be arranged to have the same area or different areas.
Accordingly, the heat generating element 100, 200 having a fusing function according to an embodiment of the present invention may be implemented as a surface-shaped heat generating element in which a plurality of heat sources 110 having a predetermined area are electrically connected to each other through the fusing parts 120, 120', 120 ″.
Therefore, the heat generating elements 100 and 200 having the fusing function according to the embodiment of the present invention can simultaneously generate heat from the heat source 110 having a predetermined area when power is applied, and thus can increase the heat generating area, and can increase the heat exchange area with air by the increased heat generating area, thereby improving reactivity.
In addition, the heat generating elements 100 and 200 having the fusing function according to an embodiment of the present invention are capable of generating heat in a predetermined area in each heat source 110, and thus even if the entire length is increased, a uniform heat generating temperature can be achieved regardless of the position.
The fusing members 120, 120', and 120 ″ may physically connect two heat sources 110 disposed at intervals along the longitudinal direction of the heat generating elements 100 and 200. Accordingly, as described above, the fusing members 120, 120', 120 ″ may connect two heat sources 110 in series.
At this time, the fusing members 120, 120', and 120 ″ are fused when the plurality of heat sources 110 generating heat when power is applied generate heat at a high temperature equal to or higher than a set temperature, and further, current flow on the plurality of heat sources 110 side can be prevented.
Accordingly, the heat generating element 100, 200 with the fusing function according to an embodiment of the present invention realizes the current interruption function by the fusing member 120, 120', 120 ″ itself, thereby preventing the fire due to overheating.
Further, since the heat generating elements 100 and 200 having the fusing function according to the embodiment of the present invention have the current interruption function in their own bodies, the self-protection function can be activated by the fusing members 120, 120', and 120 ″ even if an external controller, for example, a heater controller, fails, thereby improving stability.
Here, when the plurality of heat sources 110 connected in series generate heat at a high temperature equal to or higher than a set value, the fusing members 120, 120', and 120 ″ may be fused by heat transmitted from the heat sources 110, and may cut off current.
As an example, the fusing members 120, 120', 120 ″ may be formed of lead, copper, tin, zinc, cadmium, and one or more metal materials combining them with each other. However, the material of the fusing member 120, 120', 120 ″ is not limited thereto, but may be applied to all known materials that may be used as a fuse.
Further, the fusing members 120, 120', and 120 ″ may be arranged in a linear shape having a predetermined length, but may be arranged in a plate shape having a predetermined area, as with the heat source 110, in order to reduce the possibility of breakage due to an external force.
Such fusing members 120, 120', 120 ″ can physically connect two heat sources 110 arranged at a spaced distance from each other in various ways.
As an example, the fusing members 120, 120', 120 ″ may connect two heat sources 110 in series by way of fig. 4 to 6.
Specifically, the fusing part 120 may connect the same surfaces of two heat sources 110 disposed at a distance from each other. That is, as shown in fig. 4, the fusing members 120 may be connected to the upper surfaces of two heat sources 110 disposed at a distance from each other. In addition, the fusing members 120 may be connected to lower surfaces of the two heat sources 110 disposed at a distance from each other, respectively.
As another example, as shown in fig. 5 and 6, the fusing members 120 ', 120 ″ may include first fusing members 121, 121 ' and second fusing members 122, 122 '. In this case, the first fusing members 121 and 121 'may be connected to upper surfaces of the two heat sources 110 spaced apart from each other, respectively, and the second fusing members 122 and 122' may be connected to lower surfaces of the two heat sources 110 spaced apart from each other, respectively.
Accordingly, even if any one of the first and second fusing members 121 and 121 'and 122' is physically separated from the two heat sources 110, the other fusing member can maintain a state of being physically connected to the two heat sources 110. Accordingly, the stability of the current supply between the plurality of heat sources 110 electrically connected through the fusing parts 120', 120 ″ may be improved.
In this case, as shown in fig. 5, the first fuse members 121 and 121 'and the second fuse members 122 and 122' may be disposed so as not to contact each other between the two heat sources 110, or at least a part of the two heat sources 110 may contact each other as shown in fig. 6.
However, the connection method of the fusing members 120, 120', and 120 ″ and the heat source 110 is not limited thereto, and may be appropriately changed as long as the fusing members can be fused when the fusing members are physically connected to each other and the set temperature or higher.
The insulating member 130 may be configured to wrap a plurality of heat sources 110 aligned in a row at intervals in a length direction and fuse members 120, 120', 120 ″ connecting two heat sources 110 in series.
That is, the insulating member 130 may prevent the heat source 110 and the fusing members 120, 120', and 120 ″ as conductive members from being exposed to the outside.
Accordingly, the insulating member 130 may prevent the heat source 110 and the fusing member 120, 120', 120 ″ from being short-circuited due to contact when they are in contact with other members.
Here, the heat generating element 100, 200 having a fusing function according to an embodiment of the present invention may be configured with a pair of terminal members 141, 142 at both end portions for applying power supplied from the outside to the heat source 110 side, and the pair of terminal members 141, 142 may be connected to the heat source 110 at one end while exposing at least a portion of the length to the outside.
As an example, the insulating member 130 may include: a first insulating member 131 covering the heat source 110 and the upper surfaces of the fusing members 120, 120', and 120 ″; a second insulating member 132 covering the heat source 110 and the lower surfaces of the fusing members 120, 120', and 120 ″; the first insulating member 131 and the second insulating member 132 may be attached by an adhesive layer.
Further, the insulating member 130 may be configured to cover the plurality of heat sources 110 and one or more fusing members 120, 120', and 120 ″ at the same time.
However, the insulating member 130 is not limited thereto, but may be formed of one member.
On the other hand, the insulating member 130 may have an insulating property to perform electrical insulation, and may also have a heat resistance together to prevent damage due to heat generated at the heat source 110.
As an example, the insulating member 130 may be a film member made of a resin material having insulation and heat resistance. As a non-limiting example, the insulating member 130 may be a known Polyimide (PI) film, but is not limited thereto, and may be used without limitation as long as it has insulating and heat-resistant properties.
Further, the insulating member 130 may be formed of a coating layer on which a coating liquid having insulating and heat-resistant properties is applied, or may be a combination of a coating layer and a thin film member.
On the other hand, as shown in fig. 7, the heating element 200 with a fusing function according to an embodiment of the present invention may further include a metal sheet 150, and the metal sheet 150 is attached to one surface of the insulating member 130 by an adhesive layer.
The metal sheet 150 may be a plate-shaped spacer having a predetermined area, and may be disposed on at least one surface of the insulating member 130 covering the heat source 110 and the fusing members 120, 120', and 120 ″, and further may form an exposed surface exposed to the outside on the heat generating element 200.
Accordingly, the metal sheet 150 protects the heat source 110 from an external force, can maintain the shape of the heat source 110, and can rapidly disperse heat generated from the heat source 110.
As an example, copper or aluminum having excellent thermal conductivity may be used as a material of the metal sheet 150. However, the material of the metal sheet 150 is not limited thereto, and may be used without limitation as long as it is a material having excellent thermal conductivity.
Furthermore, the heating element 200 with a fusing function according to an embodiment of the present invention includes the metal sheet 150, and in a case where the metal sheet 150 is formed with an exposed surface exposed to the outside, the metal sheet 150 may be a hollow tube having a hollow interior. In this case, the plurality of heat sources 110, the fusing members 120, 120', 120 ″ and the insulating member 130 may be formed in a form of being inserted into the hollow type pipe, which may be realized in a plate shape by pressurization.
The drawings show that the metal sheet 150 is provided to the heating element shown in fig. 4, but the present invention is not limited thereto, and may be equally applied to the heating elements shown in fig. 5 and 6.
On the other hand, as shown in fig. 1 and 2, the heat generating elements 100 and 200 having a fusing function according to an embodiment of the present invention may be bent a plurality of times along the length direction, and further, a channel 102 for passing a fluid such as air may be formed.
That is, the heat generating elements 100 and 200 may be bent several times to alternately form the crests 104 and the troughs 106 along the longitudinal direction.
Accordingly, the heat generating element 100, 200 having a fusing function according to an embodiment of the present invention may form a channel 102 through which a fluid such as air may pass by the peak portions 104 and the valley portions 106, and the fluid may be directly heated by the heat generating element 100, 200 in the process of passing through the channel 102.
Accordingly, unlike the conventional art in which heat generated in the heat generating element is transferred to the heat sink and heated by contacting air to be heated with the heat sink, the heat generating element 100 or 200 having the fusing function according to an embodiment of the present invention can directly heat air to be heated by the heat generating element 100 or 200, thereby minimizing a heat transfer process, reducing thermal resistance that may be generated during the heat transfer process, and further improving heat density.
In addition, in the heating elements 100 and 200 having the fusing function according to the embodiment of the present invention, the contact area and the heating area with the fluid to be heated are enlarged by the channels 102 repeatedly formed along the longitudinal direction, and the heat exchange area is enlarged, so that a large amount of heat generation can be secured.
On the other hand, the heat generating elements 100, 200 having the fusing function described above may be implemented as a heating unit 300 for heating fluid.
As an example, as shown in fig. 8, the heating unit 300 may include a frame 310 for fixing the plurality of heat generating elements 100, 200. In this case, the plurality of heat generating elements 100 and 200 may be arranged at intervals in the height direction of the frame 310, and both end portions may be fixed to the frame 310.
In this case, a separate supporting member 320 may be disposed between the two heat generating elements 100 and 200 disposed along the height direction of the frame 310, and a controller 330 for controlling the overall driving of the heating unit 300 may be disposed outside the frame 310.
Here, the heat generating elements 100 and 200 may have all the structures described above.
Accordingly, the fluid to be heated can be directly heated by the heat generating element 100 in the process of passing through the passage 102 formed in the heat generating elements 100 and 200, and thus the temperature rise time can be shortened.
The above-described heat generating elements 100, 200 and heating unit 300 may also be applied to an automotive air conditioning heater provided on an air conditioner side of an automobile for heating air sucked into the air conditioner side. However, the use of the heating element and the heating unit is not limited thereto, and any product may be used as long as the temperature of the fluid is increased by heat exchange.
