HONEYCOMB STRUCTURE, ELECTRIC HEATING TYPE CARRIER, AND EXHAUST GAS CLEANING APPARATUS
To provide a honeycomb structure improved in heat generation uniformity.SOLUTION: A honeycomb structure comprises: a columnar honeycomb structure part which has an outer peripheral wall, and a partition wall which is provided at inside of the outer peripheral wall, and partitions and forms a plurality of cells forming a channel from one end face to the other end face; a first electrode layer which is provided in a belt shape in a direction where the cells extend on an outer face of the outer peripheral wall; and a second electrode layer which is provided in a belt shape in a direction where the cells extend on the outer surface of the outer peripheral wall, the second electrode layer provided facing the first electrode layer across a center axis of the honeycomb structure part. In a cross section orthogonal to a direction where the cells extend, when a coordinate axis is arranged in a radial direction, a coordinate value of a centroid O is 0, and a coordinate value of the outer surface of the outer peripheral wall is 1.00 R, an average heat capacity at 25°C per unit volume of prescribed first and second outer peripheral regions is greater than an average heat capacity at 25°C per unit volume of the first center region in the honeycomb structure.SELECTED DRAWING: Figure 2A
【課題】発熱均一性が改善されたハニカム構造体を提供する。【解決手段】外周壁と、外周壁の内側に配設され、一方の端面から他方の端面まで流路を形成する複数のセルを区画形成する隔壁と、を有する円柱状のハニカム構造部、前記外周壁の外表面においてセルの延びる方向に帯状に設けられた第一電極層、及び、前記外周壁の外表面においてセルの延びる方向に帯状に設けられた第二電極層であって、前記ハニカム構造部の中心軸を挟んで前記第一電極層と対向するように設けられた前記第二電極層、を備え、前記セルの延びる方向に直交する断面において、径方向に座標軸を取り、重心Ｏの座標値を０、前記外周壁の外表面の座標値を１．００Ｒとしたとき、所定の第一外周領域及び第二外周領域の単位体積当たりの２５℃における平均熱容量は、第一中央領域の単位体積当たりの２５℃における平均熱容量よりもそれぞれ高い、ハニカム構造体。【選択図】図２Ａ
