　従来、特許文献１に記載されたヒータ装置がある。この装置は、複数の放熱部と、複数の放熱部を挟むように配置された発熱部と、発熱部および放熱部よりも伝導率の低い低熱伝導部と、を有している。また、この装置は、低熱伝導部が発熱部および放熱部を囲うように構成され、物体が接触した際に接触した部位の温度が低下するよう構成されている。 Conventionally, there is a heater device described in Patent Document 1.

　上記特許文献１に記載された装置は、複数の放熱部を挟むように配置された発熱部がそれぞれ直線形状を成している。発明者の検討によれば、このような直線形状を成す発熱部は、緊張状態で張られたワイヤーの様にみなすことができ、発熱部に外力が加わったときの強度を十分に確保できない。本開示は、発熱部に外力が加わったときの強度をより確保できるようにすることを目的とする。 In the device described in Patent Document 1, the heat generating portions arranged so as to sandwich the plurality of heat radiating portions each have a linear shape. According to the study of the inventor, the heat generating portion having such a linear shape can be regarded as a wire stretched in a tense state, and sufficient strength cannot be secured when an external force is applied to the heat generating portion. An object of the present disclosure is to make it possible to secure more strength when an external force is applied to a heat generating portion.
　本開示の１つの観点によれば、ヒータ装置は、絶縁基材の一面に隣り合うように形成され通電により発熱する発熱部と、隣り合う発熱部の間に配置され発熱部の熱を放熱する放熱部と、を備え、隣り合う発熱部は、それぞれ曲線状を成す曲線部を有している。 According to one aspect of the present disclosure, the heater device is arranged so as to be adjacent to one surface of the insulating base material and generates heat by energization, and is arranged between the adjacent heat generating parts to dissipate the heat of the heat generating part. A heat radiating portion and a heat radiating portion are provided, and adjacent heat generating portions each have a curved portion forming a curved shape.
　このような構成によれば、隣り合う発熱部は、それぞれ曲線状を成す曲線部を有しており、このような曲線状を成す曲線部は、湾曲するように緩く張られたワイヤーのようにみなすことができる。したがって、直線形状を成す発熱部を用いた場合と比較して発熱部に外力が加わったときの強度をより確保することができる。 According to such a configuration, the adjacent heat generating portions each have a curved portion forming a curved shape, and the curved portion forming such a curved shape is like a wire loosely stretched so as to be curved. Can be regarded. Therefore, it is possible to secure more strength when an external force is applied to the heat generating portion as compared with the case where the heat generating portion having a linear shape is used.

The heater device 20 generates heat when electric power is supplied. As shown in FIG. 2, the heater device 20 has a surface having a heat generating surface 20a that radiates radiant heat H mainly in a direction perpendicular to the surface in order to warm an object positioned in a direction perpendicular to the surface thereof. It can be called a state heater.
　次に、ヒータ装置２０の構成について説明する。図３～図４に示すように、ヒータ装置２０は、発熱部２１、放熱部２２、絶縁基材２５およびカバー部材２６を備えている。なお、図３は、ヒータ装置２０の正面図であって、カバー部材２６を透過した図となっている。 Next, the configuration of the heater device 20 will be described. As shown in FIGS. 3 to 4, the heater device 20 includes a heat generating portion 21, a heat radiating portion 22, an insulating base material 25, and a cover member 26. Note that FIG. 3 is a front view of the heater device 20 and is a view through which the cover member 26 is transmitted.
　絶縁基材２５は、軸Ｘと軸Ｙによって規定されるＸ－Ｙ平面に沿って広がる板状部材によって構成されている。絶縁基材２５は、軸Ｚの方向に厚さをもつ。絶縁基材２５は、ほぼ四角形の薄い板状に形成されている。絶縁基材２５は、高い絶縁性を有し、かつ、高温に耐える樹脂材料、例えば、ポリイミドフィルムによって構成されている。絶縁基材２５における乗員側の面に、発熱部２１、放熱部２２およびカバー部材２６が形成されている。 The insulating base material 25 is composed of a plate-shaped member extending along an XY plane defined by an axis X and an axis Y. The insulating base material 25 has a thickness in the direction of the axis Z. The insulating base material 25 is formed in a substantially quadrangular thin plate shape. The insulating base material 25 is made of a resin material having high insulating properties and withstanding high temperatures, for example, a polyimide film. A heat generating portion 21, a heat radiating portion 22, and a cover member 26 are formed on the surface of the insulating base material 25 on the occupant side.
　発熱部２１は、線状を成しており、絶縁基材２５の一面に蛇行するように形成されている。すなわち、絶縁基材２５の一面に、波形状を成す発熱部２１が大きく蛇行するように形成されている。 The heat generating portion 21 is linear and is formed so as to meander on one surface of the insulating base material 25. That is, the heat generating portion 21 having a wavy shape is formed on one surface of the insulating base material 25 so as to meander greatly.
　発熱部２１は、高い熱伝導率を有する材料によって作られている。また、発熱部２１は、導電性を有する部材によって作られている。具体的には、発熱部２１は、銅、銅とスズとの合金（Ｃｕ－Ｓｎ）、銀、スズ、ステンレス鋼、ニッケル、ニクロムなどの金属およびこれらを含む合金を用いて構成することができる。 The heat generating portion 21 is made of a material having high thermal conductivity. Further, the heat generating portion 21 is made of a conductive member. Specifically, the heat generating portion 21 can be configured by using a metal such as copper, an alloy of copper and tin (Cu—Sn), silver, tin, stainless steel, nickel, and nichrome, and an alloy containing these. ..
　発熱部２１の両端には、それぞれ接続端子２７が形成されている。各接続端子２７は、不図示の制御部に接続されている。 Connection terminals 27 are formed at both ends of the heat generating portion 21. Each connection terminal 27 is connected to a control unit (not shown).
　放熱部２２は、発熱部２１からの熱を拡散して放熱するもので、Ｘ－Ｙ平面方向に拡がるように形成されている。放熱部２２は、矩形形状を成している。 The heat radiating unit 22 diffuses and dissipates heat from the heat generating unit 21, and is formed so as to spread in the XY plane direction. The heat radiating unit 22 has a rectangular shape.
　放熱部２２は、隣り合う発熱部２１の間に配置されている。また、放熱部２２は、絶縁基材２５の一面において格子状に配置されている。すなわち、放熱部２２は、絶縁基材２５の一面においてＸ軸方向に一定間隔毎に配置されるとともに、Ｘ軸方向と直交するＹ軸方向に一定間隔毎に配置されている。 The heat radiating unit 22 is arranged between the adjacent heat generating units 21. Further, the heat radiating portions 22 are arranged in a grid pattern on one surface of the insulating base material 25. That is, the heat radiating portions 22 are arranged on one surface of the insulating base material 25 at regular intervals in the X-axis direction and at regular intervals in the Y-axis direction orthogonal to the X-axis direction.
　また、各放熱部２２は、隣り合う一方の発熱部２１におけるＹ軸方向に凸となる波形状の山部と他方の発熱部２１におけるＹ軸方向に凸となる波形状の山部の間となる位置に形成されている。 Further, each heat radiating portion 22 is located between a wave-shaped mountain portion that is convex in the Y-axis direction in one adjacent heat generating portion 21 and a wave-shaped peak portion that is convex in the Y-axis direction in the other heat generating portion 21. It is formed in the position of.
　カバー部材２６は、発熱部２１を保護するものである。カバー部材２６は、電気絶縁性を有する部材によって構成されている。また、カバー部材２６は、発熱部２１よりも熱伝導率の低い低熱伝導部材によって構成されている。 The cover member 26 protects the heat generating portion 21. The cover member 26 is made of a member having electrical insulation. Further, the cover member 26 is composed of a low thermal conductive member having a lower thermal conductivity than the heat generating portion 21.
　制御部から各接続端子２７の間に所定の電圧が印加されると、発熱部２１に電流が流れ発熱部２１が発熱する。そして、ヒータ装置２０は、乗員１２に暖かさを感じさせる輻射熱Ｈを放射する。また、発熱部２１からの熱は放熱部２２によって拡散され放熱される。放熱部２２によって発熱部２１からの熱が拡散されることにより発熱面２０ａの温度ムラが低減される。 When a predetermined voltage is applied between the control unit and each connection terminal 27, a current flows through the heat generating unit 21 and the heat generating unit 21 generates heat. Then, the heater device 20 radiates radiant heat H that makes the occupant 12 feel warm. Further, the heat from the heat generating unit 21 is diffused by the heat radiating unit 22 and dissipated. The heat from the heat generating portion 21 is diffused by the heat radiating portion 22, so that the temperature unevenness of the heat generating surface 20a is reduced.
　本実施形態のヒータ装置２０の発熱部２１は、絶縁基材２５の一面に隣り合うように形成され、通電により発熱する。図５に示すように、隣り合う発熱部２１は、それぞれ曲線状を成す曲線部２１１および直線状を成す直線部２１２を有している。発熱部２１は、絶縁基材２５の一面に、波形状を成すように曲がって形成されている。 The heat generating portion 21 of the heater device 20 of the present embodiment is formed so as to be adjacent to one surface of the insulating base material 25, and generates heat when energized. As shown in FIG. 5, the adjacent heat generating portions 21 have a curved portion 211 having a curved shape and a straight portion 212 having a linear shape, respectively. The heat generating portion 21 is formed on one surface of the insulating base material 25 by being bent so as to form a wave shape.
　隣り合う発熱部２１は、それぞれ一方向（すなわちＹ方向）に突出する波形状の山部２１Ｍと、Ｙ方向と反対方向に突出する波形状の谷部２１Ｖと、を有している。そして、隣り合う一方の発熱部２１の山部２１Ｍと、隣り合う他方の発熱部２１の山部２１Ｍとが対向するように形成されている。 The adjacent heat generating portions 21 have a wave-shaped peak portion 21M protruding in one direction (that is, the Y direction) and a wave-shaped valley portion 21V protruding in the direction opposite to the Y direction. The mountain portion 21M of one adjacent heat generating portion 21 and the mountain portion 21M of the other adjacent heat generating portion 21 are formed so as to face each other.
　放熱部２２は、隣り合う一方の発熱部２１の山部２１Ｍと、隣り合う他方の発熱部２１の山部２１Ｍとの間に配置されている。 The heat radiating portion 22 is arranged between the mountain portion 21M of one adjacent heat generating portion 21 and the mountain portion 21M of the other adjacent heat generating portion 21.
　図６の（ａ）部は、本実施形態の波形状の発熱部２１のＸ－Ｙ平面および発熱部２１が形成された部位の絶縁基材２５の断面形状を表している。また、図６の（ｂ）部は、比較例としての直線状の発熱部２１のＸ－Ｙ平面および発熱部２１が形成された部位の絶縁基材２５の断面形状を表している。 Part (a) of FIG. 6 shows the cross-sectional shape of the insulating base material 25 in the XY plane of the wave-shaped heat generating portion 21 of the present embodiment and the portion where the heat generating portion 21 is formed. Further, the portion (b) of FIG. 6 represents the cross-sectional shape of the insulating base material 25 at the portion where the linear heat generating portion 21 and the heat generating portion 21 are formed as a comparative example.
　図６の（ａ）部に示すように、発熱部２１が波形状を成している場合、発熱部２１にＺ方向の外力がかかった際に、発熱部２１が比較的柔軟に動くことができる。これに対し、図６の（ｂ）部に示すように、発熱部２１が直線状を成している場合、発熱部２１にＺ方向の外力がかかった際に、発熱部２１が柔軟に動くことができない。 As shown in the part (a) of FIG. 6, when the heat generating part 21 has a wavy shape, the heat generating part 21 may move relatively flexibly when an external force in the Z direction is applied to the heat generating part 21. can. On the other hand, as shown in the portion (b) of FIG. 6, when the heat generating portion 21 has a linear shape, the heat generating portion 21 flexibly moves when an external force in the Z direction is applied to the heat generating portion 21. Can't.
　直線状を成している発熱部２１は、緊張状態で張られたワイヤーのようにみなすことができる。このような発熱部２１は、外力がかかると切れやすい。 The linear heat generating portion 21 can be regarded as a wire stretched in a tense state. Such a heat generating portion 21 is easily cut when an external force is applied.
　これに対し、波形状を成している発熱部２１は、湾曲するように緩く張られたワイヤーのようにみなすことができる。このような発熱部２１は、外力がかかると、この外力がかかった部位が変位して切れにくい。 On the other hand, the heat generating portion 21 having a wavy shape can be regarded as a wire loosely stretched so as to be curved. When an external force is applied to such a heat generating portion 21, the portion to which the external force is applied is displaced and difficult to cut.
　したがって、波形状を成している発熱部２１の方が、直線状を成している発熱部２１よりも外力が加わったときの強度を大きくすることができる。 Therefore, the wave-shaped heat generating portion 21 can have a higher strength when an external force is applied than the linear heat generating portion 21.
　また、図６の（ａ）部におけるＡ点とＢ点の間の直線距離は、図６の（ｂ）部のＡ点とＢ点の間の距離と同じになっている。なお、図６の（ａ）部における発熱部２１の線幅と、図６の（ｂ）部における発熱部２１の線幅は同一となっている。 Further, the linear distance between the points A and B in the part (a) of FIG. 6 is the same as the distance between the points A and B in the part (b) of FIG. The line width of the heat generating portion 21 in the portion (a) of FIG. 6 and the line width of the heat generating portion 21 in the portion (b) of FIG. 6 are the same.
　ここで、Ａ点とＢ点の間の発熱部２１を形成するのに必要とされる導電性部材の量は、直線状のものよりも波形状のものの方が多くなる。したがって、波形状の発熱部２１の方が、直線状の発熱部２１よりも外力が加わったときの強度が大きくなる。 Here, the amount of the conductive member required to form the heat generating portion 21 between the points A and B is larger in the wavy shape than in the linear shape. Therefore, the wave-shaped heat-generating portion 21 has a higher strength when an external force is applied than the linear heat-generating portion 21.
　このような観点からも、波形状の発熱部２１の方が、直線状の発熱部２１よりも外力が加わったときの強度を大きくすることができるといえる。 From this point of view, it can be said that the wave-shaped heat generating portion 21 can have a higher strength when an external force is applied than the linear heat generating portion 21.
　以上、説明したように、本実施形態のヒータ装置は、絶縁基材２５の一面に隣り合うように形成され、通電により発熱する発熱部２１と、隣り合う発熱部２１の間に配置され、発熱部２１の熱を放熱する放熱部２２と、を備えている。そして、隣り合う発熱部２１は、それぞれ曲線状を成す曲線部２１１を有している。 As described above, the heater device of the present embodiment is formed so as to be adjacent to one surface of the insulating base material 25, and is arranged between the heat generating portion 21 that generates heat by energization and the adjacent heat generating portion 21, and generates heat. A heat radiating unit 22 that dissipates heat from the unit 21 is provided. The adjacent heat generating portions 21 each have a curved portion 211 having a curved shape.
　このような構成によれば、隣り合う発熱部２１は、それぞれ曲線状を成す曲線部２１１を有しており、このような曲線状を成す曲線部２１１は、湾曲するように緩く張られたワイヤーのようにみなすことができる。 According to such a configuration, the adjacent heat generating portions 21 each have a curved portion 211 forming a curved shape, and the curved portion 211 forming such a curved shape is a wire loosely stretched so as to be curved. Can be regarded as.
　したがって、直線形状を成す発熱部を用いた場合と比較して発熱部２１に外力が加わったときの強度をより確保することができる。 Therefore, it is possible to secure more strength when an external force is applied to the heat generating portion 21 as compared with the case where the heat generating portion having a linear shape is used.
　また、隣り合う発熱部２１は、それぞれＹ方向に突出する波形状の山部２１Ｍと、Ｙ方向と反対方向に突出する波形状の谷部２１Ｖと、を有している。 Further, the adjacent heat generating portions 21 have a wave-shaped peak portion 21M protruding in the Y direction and a wave-shaped valley portion 21V protruding in the direction opposite to the Y direction, respectively.
　また、隣り合う一方の発熱部２１の山部２１Ｍと、隣り合う他方の発熱部２１の山部２１Ｍとが対向するように形成されている。 Further, the mountain portion 21M of one adjacent heat generating portion 21 and the mountain portion 21M of the other adjacent heat generating portion 21 are formed so as to face each other.
　そして、放熱部２２は、隣り合う一方の発熱部２１の山部２１Ｍと、隣り合う他方の発熱部２１の山部２１Ｍとの間に配置されている。 Then, the heat radiating portion 22 is arranged between the mountain portion 21M of one adjacent heat generating portion 21 and the mountain portion 21M of the other adjacent heat generating portion 21.
　このように、隣り合う一方の発熱部２１の山部２１Ｍと、隣り合う他方の発熱部２１の山部２１Ｍとが対向するように形成し、隣り合う一方の発熱部２１の山部２１Ｍと、隣り合う他方の発熱部２１の山部２１Ｍとの間に放熱部２２を配置することができる。 In this way, the mountain portion 21M of one adjacent heat generating portion 21 and the mountain portion 21M of the other adjacent heat generating portion 21 are formed so as to face each other, and the mountain portion 21M of one adjacent heat generating portion 21 is formed. The heat radiating portion 22 can be arranged between the mountain portion 21M of the other adjacent heat generating portion 21 and the mountain portion 21M.
　（第２実施形態）
　第２実施形態に係るヒータ装置について図７を用いて説明する。本実施形態のヒータ装置２０は、上記第１実施形態のヒータ装置２０と比較して放熱部２２の配置が異なる。 (Second Embodiment)
The heater device according to the second embodiment will be described with reference to FIG. The heater device 20 of the present embodiment has a different arrangement of the heat radiating unit 22 than the heater device 20 of the first embodiment.
