發明說明： 【發明所屬之技術領域】 [0001] 本發明涉及一種面熱源，尤其涉及一種基於奈米碳管的 面熱源。 【先前技術】 [0002] 熱源在人們的生產、生活、科研中起著重要的作用。面 熱源係熱源的一種，其特點為面熱源具有一平面結構， 將待加熱物體置於該平面結構的上方對物體進行加熱， 故，面熱源可對待加熱物體的各個部位同時加熱，加熱 面廣、加熱均勻且效率較高。面熱源已成功用於工業領 域、科研領域或生活領域等，如電加熱器、紅外治療儀 、電暖器等。 [0003] 先前面熱源一般包括一加熱層和至少兩個電極，該至少 兩個電極設置於該加熱層的表面，並與該加熱層的表面 電連接。當連接加熱層上的電極通入低電壓電流時，熱 量立刻從加熱層釋放出來。現在市售的面熱源通常採用 金屬製成的電熱絲作為加熱層進行電熱轉換。然而，電 熱絲的強度不高易於折斷，特別係彎曲或繞折成一定角 度時，故應用受到限制。另，以金屬製成的電熱絲所產 生的熱量係以普通波長向外II射的，其電熱轉換效率不 高不利於節省能源。 [0004] 非金屬碳纖維導電材料的發明為面熱源的發展帶來了突 破。採用碳纖維的加熱層通常在碳纖維外部塗覆一層防 水的絕緣層用作電熱轉換的元件以代替金屬電熱絲。由 於碳纖維具有較好的韌性，這在一定程度上解決了電熱 09712826#單編號 A〇101 第3頁/共20頁 1013399291-0 1380733 101年.10月18曰修正替換頁 絲強度不高易折斷的缺點。然而，由於碳纖維仍係以普 通波長向外散熱，故並未解決電熱轉換率低的問題。為 解決上述問題，採用碳纖維的加熱層一般包括多根碳纖 維熱源線鋪設而成。該碳纖維熱源線為一外表包裹有化 纖或者棉線的導電芯線。該化纖或者棉線的外面浸塗一 層防水阻燃絕緣材料。所述導電芯線由多根碳纖維與多 根表面黏塗有遠紅外塗料的棉線纏繞而成。導電芯線中 加入黏塗有遠紅外塗料的棉線，一來可增強芯線的強度 ，二來可使通電後碳導纖維發出的熱量能以紅外波長向 外輻射8 [0005] 然而，採用碳纖維紙作為加熱層具有以下缺點：第一， 碳纖維強度不夠大，柔性不夠好，容易破裂，需要加入 棉線提高碳纖維的強度，限制了其應有範圍；第二，碳 纖維本身的電熱轉換效率較低，需加入黏塗有遠紅外塗 料的棉線提高電熱轉換效率，不利於節能環保；第三， 需先製成碳纖維熱源線再製成加熱層，不利於大面積製 作，不利於均勻性的要求，同時，不利於微型面熱源的 製作。 [0006] 有鑒於此，提供一種具有強度大，電熱轉換效率較高， 有利於節省能源且發熱均勻，大小可控，可製成大面積 或者微型的面熱源實為必要。 【發明内容】 [0007] —種面熱源，該面熱源包括一第一電極、一第二電極和 一加熱層。所述第一電極和第二電極間隔設置於該加熱 層上，並與該加熱層電接觸。該加熱層包括複數個線狀 ό麵26产單编號A〇101 第4頁/共20頁 1013399291-0 1380733 101年10月18日修正替換頁 奈米碳管結構。 [0008] 相較於先前技術，所述之面熱源具有以下優點：第一， 由於奈米碳管具有較好的強度及韌性，線狀奈米碳管結 構的強度較大，柔性較好，不易破裂，使其具有較長的 使用壽命。第二，線狀奈米碳管結構中的奈米碳管均勻 分佈，因此具有均勻的厚度及電阻，發熱均勻，奈米碳 管的電熱轉換效率高，故該面熱源具有升溫迅速、熱滯 後小、熱交換速度快的特點。第三，奈米碳管的直徑較 小，使得線狀奈米碳管結構具有較小的厚度，可製備微 型面熱源，應用於微型器件的加熱。 【實施方式】 [0009] 以下將結合附圖詳細說明本技術方案面熱源。 [0010] 請參閱圖1及圖2，本技術方案實施例提供一種面熱源10 ，該面熱源10包括一基底18、一反射層17、一加熱層16 、一第一電極12、一第二電極14和一絕緣保護層15。所 述反射層17設置於基底18的表面。所述加熱層16設置於 所述反射層17的表面。所述第一電極12和第二電極14間 隔設置於所述加熱層16的表面，並與該加熱層16電接觸 ，用於使所述加熱層16中流過電流。所述絕緣保護層15 設置於所述加熱層16的表面，並將所述第一電極12和第 二電極14覆蓋，用於避免所述加熱層16吸附外界雜質。 [0011] 所述基底18形狀不限，其具有一表面用於支撐加熱層16 或者反射層17。優選地，所述基底18為一板狀基底，其 材料可為硬性材料，如：陶竞、玻璃、樹脂、石英等， 亦可選擇柔性材料，如：塑膠或柔性纖維等。當為柔性 1013399291-0 09712826#單編號A〇1〇l 第5頁/共20頁 1380733 r—- 101年.10月18日核正替换頁 材料時，該面熱源10在使用時可根據需要彎折成任意形 狀。其中，基底18的大小不限，可依據實際需要進行改 變。本實施例優選的基底18為一陶瓷基板。另，當加熱 層16具有一定的自支撐性及穩定性時，所述面熱源10中 的基底18為一可選擇的結構。 [0012] 所述反射層17的設置用來反射加熱層16所發的熱量，從 而控制加熱的方向，用於單面加熱，並進一步提高加熱 的效率。所述反射層17的材料為一白色絕緣材料，如： 金屬氧化物、金屬鹽或陶瓷等。本實施例中，反射層17 為三氧化二鋁層，其厚度為100微米~0. 5毫米。該反射層 17可通過濺射或其他方法形成於該基底18表面。可以理 解，所述反射層17也可設置在基底18遠離加熱層16的表 面，即所述基底18設置於所述加熱層16和所述反射層17 之間，進一步加強反射層17反射熱量的作用。所述反射 層17為一可選擇的結構。所述加熱層16可直接設置在基 底18的表面，此時面熱源10的加熱方向不限，可用於雙 面加熱。 [0013] 所述加熱層16包括複數個線狀奈米碳管結構160。所述複 數個線狀奈米碳管結構160平行鋪設，或者交叉鋪設於所 述支撐體18表面。其中，線狀奈米碳管結構160之間交叉 的角度不限。所述相鄰兩個平行的線狀奈米碳管結構160 之間的距離為0微米〜30微米。本實施例中，優選相鄰兩 個平行的線狀奈米碳管結構160間隔的距離為20微米。可 以理解，所述複數個線狀奈米碳管結構160排列或者鋪設 的方式不限，只需確保形成一均勻的加熱層16即可。進 _282一單编號 A〇101 第6頁/共20頁 1013399291-0 1380733 101年10月18日梭正替換頁 一步地，所述加熱層16中至少部分線狀奈米碳管結構160 沿從所述第一電極22向第二電極24延伸的方向鋪設於所 述支撐體18表面，以確保流經線狀奈米碳管結構160的電 流最大。所述交叉鋪設的線狀奈米碳管結構160具有很好 的韌性與自支撐性，無需基底18。當面熱源10不包括基 底18時，所述反射層17可直接設置於所述加熱層16的表 面。所述加熱層16的厚度為3毫米〜25毫米。 [0014] 所述線狀奈米碳管結構160包括至少一根奈米碳管長線 161。諳參閱圖3及圖4，優選地所述線狀奈米碳管結構 160係由多根奈米碳管長線161組成的束狀結構或者由多 根奈米碳管長線161組成的絞線結構。所述線狀奈米碳管 結構160的直徑為20微米〜2毫米，其大小由奈米碳管長線 161的根數及直徑大小決定，奈米碳管長線161的直徑越 大，根數越多，線狀奈米碳管結構160的直徑越大，反之 ，線狀奈米碳管結構160的直徑越小。所述線狀奈米碳管 結構160的長度大小由奈米碳管長線161的長度大小決定 。本實施例中所述線狀奈米碳管結構160係由多根奈米碳 管長線161組成的束狀結構，直徑為50微米。 « [0015] 請參閱圖5及圖6，所述奈米碳管長線161係由複數個首尾 相連的奈米碳管束組成的束狀結構或者絞線結構。所述 奈米碳管長線包括沿奈米碳管長線1 61的軸向方向擇優取 向排列的奈米碳管。具體地，所述束狀結構的奈米碳管 長線161可通過有機溶劑處理所述奈米碳管薄膜，或者通 過直接拉取較窄寬度的奈米碳管陣列獲得。該奈米碳管 長線1 61中奈米碳管沿奈米碳管長線的軸向方向平行排列 097麗單編號A_ 1013399291-0 第7頁/共20頁 1380733 _ 101年10月18日修正替换頁 。所述絞線結構奈米碳管長線161可通過對束狀結構的奈 米碳管長線161施加機械外力扭轉獲得。扭轉後該奈米碳 管長線161中奈米碳管沿奈米碳管長線的軸向方向螺旋排 列。 [0016] 所述奈米碳管長線161的直徑與長度和奈米碳管陣列所生 長的基底的尺寸有關。可根據實際需求制得。本實施例 中，採用氣相沈積法在4英寸的基底生長超順排奈米碳管 陣列。所述奈米碳管長線161的直徑為1微米〜100微米， 長度為50毫米〜100毫米。 [0017] 所述線狀奈米碳管結構160中的奈米碳管為單壁奈米碳管 、雙壁奈米碳管或者多壁奈米碳管。當所述線狀奈米碳 管結構160中的奈米碳管為單壁奈米碳管時，該單壁奈米 碳管的直徑為0.5奈米~50奈米。當所述線狀奈米碳管結 構160中的奈米碳管為雙壁奈米碳管時，該雙壁奈米碳管 的直徑為1.0奈米〜50奈米。當所述線狀奈米碳管結構 160中的奈米碳管為多壁奈米碳管時，該多壁奈米碳管的 直徑為1.5奈来〜50奈米。 [0018] 所述第一電極12和第二電極14由導電材料組成，該第一 電極12和第二電極14的形狀不限，可為導電薄膜、金屬 -

[Prior Art] [0002] Heat sources play an important role in people's production, life, and research. The surface heat source is a heat source, which is characterized in that the surface heat source has a planar structure, and the object to be heated is placed above the planar structure to heat the object, so that the surface heat source can simultaneously heat various parts of the object to be heated, and the heating surface is wide. Uniform heating and high efficiency. Surface heat sources have been successfully used in industrial fields, scientific research fields or living areas, such as electric heaters, infrared therapeutic devices, and electric heaters. The front front heat source generally includes a heating layer and at least two electrodes disposed on a surface of the heating layer and electrically connected to a surface of the heating layer. When the electrode connected to the heating layer is supplied with a low voltage current, the heat is immediately released from the heating layer. Commercially available surface heat sources are usually electrothermally converted using a heating wire made of metal as a heating layer. However, the strength of the heating wire is not high and it is easy to break, especially when it is bent or folded into a certain angle, so the application is limited. In addition, the heat generated by the heating wire made of metal is emitted at a normal wavelength to the outside, and the electrothermal conversion efficiency is not high, which is disadvantageous for saving energy. [0004] The invention of non-metallic carbon fiber conductive materials has brought about a breakthrough in the development of surface heat sources. A heating layer using carbon fibers is usually coated with a water-repellent insulating layer on the outside of the carbon fibers as an electrothermal conversion element instead of the metal heating wire. Due to the good toughness of carbon fiber, this solves the electric heating to a certain extent. 09712826#Single number A〇101 Page 3/Total 20 pages 1013399291-0 1380733 101. October 18曰 Correction replacement page strength is not easy to break Shortcomings. However, since the carbon fiber is still radiated outward at a normal wavelength, the problem of low electrothermal conversion rate is not solved. In order to solve the above problems, the heating layer using carbon fiber generally comprises a plurality of carbon fiber heat source lines. The carbon fiber heat source line is a conductive core wire wrapped with a chemical fiber or a cotton thread. The outer surface of the chemical fiber or cotton thread is dip coated with a waterproof and flame-retardant insulating material. The conductive core wire is formed by winding a plurality of carbon fibers and a plurality of cotton wires coated with a far-infrared coating. The cotton wire coated with far-infrared coating is added to the conductive core wire to enhance the strength of the core wire. Secondly, the heat generated by the carbon fiber after the energization can be radiated outward at the infrared wavelength. [0005] However, carbon fiber paper is used as the carbon fiber paper. The heating layer has the following disadvantages: First, the carbon fiber is not strong enough, the flexibility is not good enough, and it is easy to be broken. It is necessary to add cotton wire to increase the strength of the carbon fiber, which limits its proper range; secondly, the carbon fiber itself has low electrothermal conversion efficiency and needs to be added. The cotton wire coated with far-infrared coating improves the electrothermal conversion efficiency, which is not conducive to energy conservation and environmental protection. Thirdly, it is necessary to first make a carbon fiber heat source line and then make a heating layer, which is not conducive to large-area production, which is not conducive to uniformity requirements, and at the same time, disadvantageous. The production of miniature surface heat sources. [0006] In view of the above, it is necessary to provide a surface heat source with large strength, high electrothermal conversion efficiency, favorable energy saving, uniform heat generation, and controllable size, and can be made into a large area or a miniature surface. SUMMARY OF THE INVENTION [0007] A seed surface heat source includes a first electrode, a second electrode, and a heating layer. The first electrode and the second electrode are disposed on the heating layer at intervals and are in electrical contact with the heating layer. The heating layer includes a plurality of linear surfaces. 26 Production No. A 〇 101 Page 4 / Total 20 pages 1013399291-0 1380733 October 18, 2011 Revision Replacement Page Carbon nanotube structure. Compared with the prior art, the surface heat source has the following advantages: First, since the carbon nanotube has better strength and toughness, the linear carbon nanotube structure has higher strength and better flexibility. Not easy to break, making it have a long service life. Second, the carbon nanotubes in the linear carbon nanotube structure are evenly distributed, so that the thickness and resistance are uniform, the heat is uniform, and the electrothermal conversion efficiency of the carbon nanotubes is high, so the surface heat source has rapid heating and thermal hysteresis. Small, fast heat exchange features. Third, the diameter of the carbon nanotubes is small, so that the linear carbon nanotube structure has a small thickness, and a micro-surface heat source can be prepared for heating of the micro device. [Embodiment] [0009] The surface heat source of the present technical solution will be described in detail below with reference to the accompanying drawings. Referring to FIG. 1 and FIG. 2 , the embodiment of the present invention provides a surface heat source 10 including a substrate 18 , a reflective layer 17 , a heating layer 16 , a first electrode 12 , and a second surface .

The heating layer 16 is disposed on the surface of the reflective layer 17. The first electrode 12 and the second electrode 14 are disposed on the surface of the heating layer 16 and are in electrical contact with the heating layer 16 for flowing a current in the heating layer 16. The insulating protective layer 15 is disposed on the surface of the heating layer 16 and covers the first electrode 12 and the second electrode 14 for preventing the heating layer 16 from adsorbing external impurities. [0011] The substrate 18 is not limited in shape, and has a surface for supporting the heating layer 16 or the reflective layer 17. Preferably, the substrate 18 is a plate-shaped substrate, and the material thereof may be a hard material such as ceramics, glass, resin, quartz, etc., and a flexible material such as plastic or flexible fiber may also be selected.

The size of the substrate 18 is not limited and can be changed according to actual needs. The preferred substrate 18 of this embodiment is a ceramic substrate. In addition, the substrate 18 in the surface heat source 10 is an optional structure when the heating layer 16 has a certain degree of self-supportingness and stability. [0012] The reflective layer 17 is arranged to reflect the heat generated by the heating layer 16, thereby controlling the direction of heating for single-sided heating and further improving the efficiency of heating. The material of the reflective layer 17 is a white insulating material such as a metal oxide, a metal salt or a ceramic. 5毫米。 The thickness of the layer is from 100 microns to 0. 5 mm. The reflective layer 17 can be formed on the surface of the substrate 18 by sputtering or other methods. It can be understood that the reflective layer 17 can also be disposed on the surface of the substrate 18 away from the heating layer 16, that is, the substrate 18 is disposed between the heating layer 16 and the reflective layer 17, further enhancing the reflective layer 17 to reflect heat. effect. The reflective layer 17 is an alternative structure. The heating layer 16 can be directly disposed on the surface of the substrate 18, and the heating direction of the surface heat source 10 is not limited, and can be used for double-sided heating. [0013] The heating layer 16 includes a plurality of linear carbon nanotube structures 160. The plurality of linear carbon nanotube structures 160 are laid in parallel or cross-laid on the surface of the support 18. Among them, the angle of intersection between the linear carbon nanotube structures 160 is not limited.
