Honeycomb structure

摘要

A cylindrical honeycomb structure 1 has a partition wall 3 forming A channels 5 and B channels 6. The A channels 5 are open at a first end surface 1a and closed at a second end surface 1b. The B channels 6 are closed at the first end surface 1a and open at the second end surface 1b. The B channels 6 include a first B channel 11 and a second B channel 13 extending substantially in parallel to each other. The A channels 5 include first A channels 10, which surround the first B channel at the first end surface, and second A channels 12, which surround the second B channel at the first end surface. The partition wall 3 has a first group partition wall 18, which separates adjacent channels of the first A channels 10 and the second A channels 12 from each other.

1. A honeycomb structure comprising:
a first end surface and a second end surface facing each other; and partition walls that form a plurality of A channels and a plurality of B channels extending in a facing direction between the first end surface and the second end surface, wherein the plurality of A channels are open at the first end surface and closed at the second end surface, the plurality of B channels are closed at the first end surface and open at the second end surface, the plurality of B channels include a first B channel and a second B channel extending substantially parallel to each other, the plurality of A channels include a plurality of first A channels that surround the first B channel at the first end surface and a plurality of second A channels that surround the second B channel at the first end surface, the plurality of first A channels are adjacent to the first B channel but are not adjacent to the second B channel at the first end surface, the plurality of second A channels are adjacent to the second B channel but are not adjacent to the first B channel at the first end surface, and the partition walls include a first standard wall that separates the plurality of first A channels and the first B channel from each other, a second standard wall that separates the plurality of second A channels and the second B channel from each other, a first common wall that separates adjacent two of the first A channels from each other, a second common wall that separates adjacent two of the second A channels from each other, and a first partition wall that separates adjacent channels of the first A channels and the second A channels from each other, wherein the first partition wall is thinner than the first standard wall and the second standard wall.
