Heat exchange member, heat exchanger and heat conductive member

A heat exchange member, comprising:

• a hollow honeycomb structure comprising:
• an outer peripheral wall;
• an inner peripheral wall;
• and partition walls arranged between the outer peripheral wall and the inner peripheral wall, the partition walls defining a plurality of cells, each of the plurality of cells extending from a first end face to a second end face to form a flow path for a first fluid;
• and
• a covering member being configured to cover an outer peripheral surface of the outer peripheral wall,
• wherein in a cross section of the honeycomb structure orthogonal to a flow path direction for the first fluid, the partition walls comprise first partition walls extending in a radial direction and second partition walls extending in a circumferential direction,
• wherein a part of at least one of the outer peripheral wall, the inner peripheral wall and the second partition walls comprises at least one slit,
• wherein a thickness of each first partition wall is higher than a thickness of each second partition wall, and
• wherein the number of the slits in the circumferential direction is from 3 to 10.

A heat conductive member, comprising a honeycomb structure comprising:

• an outer peripheral wall;
• and partition walls arranged on an inner side of the outer peripheral wall, the partition walls defining a plurality of cells, each of the plurality of cells extending from a first end face to a second end face to form a flow path for a first fluid,
• wherein the outer peripheral wall and the partition walls comprise a Si—SiC material based on SiC particles as an aggregate, wherein a metal Si is contained between the SiC particles,
• wherein in a cross section of the honeycomb structure orthogonal to a flow path direction for the first fluid, the partition walls comprise first partition walls extending in a radial direction and second partition walls extending in a circumferential direction,
• wherein a part of at least one of the outer peripheral wall and the second partition walls comprises at least one slit,
• wherein a thickness of each first partition wall is higher than a thickness of each second partition wall, and
• wherein the number of the slits in the circumferential direction is from 3 to 10.
