    • Provided are a honeycomb type heating device capable of causing a honeycomb substrate to come into face-contact with a heater in a wide range and of heating a target even when a part of the heater is broken and a method of using the same.
      The honeycomb type heating device includes: a pillar-shaped honeycomb substrate 2 which includes a porous partition wall defining a plurality of cells extending from one end face to the other end face and a circumferential wall 3 surrounding the partition wall; and a plurality of heaters 9 which are disposed adjacently in a circumferential direction of an outer circumferential face 8 that is an outer surface of the circumferential wall 3, on the outer circumferential face 8. Each heater 9 is a resistance heating heater which radiates heat by a current supplied thereto, each heater 9 comes into face-contact with the outer circumferential face 8, and a ratio of a total area of a portion covered by the heaters 9 of the outer circumferential face 8 with respect to the entire area of the outer circumferential face 8 is 50 to 100%.
    • 本发明提供一种蜂窝型加热装置,其能够使蜂窝状基板与宽范围的加热器进行面接触,并且即使当加热器的一部分被破坏时也对其进行加热及其使用方法。 蜂窝型加热装置包括:柱状蜂窝基板2,其包括多孔分隔壁,多孔分隔壁限定从一个端面延伸到另一端面的多个单元;以及围绕分隔壁的周壁3; 以及在外周面8上作为周壁3的外表面的外周面8的周向相邻配置的多个加热器9.每个加热器9是通过以下方式散热的电阻加热加热器 供给的电流,各加热器9与外周面8面接触,外周面8的加热器9所覆盖的部分的总面积相对于外周面8的整个面积的比例 圆周面8为50〜100%。
