Claim 0:
1. A tube body for a heat exchanger, in particular in a motor vehicle or in a building, the tube body comprising:
an outer cover, which extends in a longitudinal direction and limits an inner volume in a circumferential direction, and which can be flowed through in the longitudinal direction;
two outer intermediate walls, which are arranged located opposite in the outer cover in a width direction running transversely to the longitudinal direction, wherein the respective outer intermediate wall of the outer cover is next-adjacent in the width direction; and
at least one inner intermediate wall, which is arranged in the outer cover in the width direction between the outer intermediate walls,
wherein the intermediate walls are spaced apart relative to one another in the width direction and limit passages that are separated from one another within the outer cover, which can each be flowed through in the longitudinal direction,
wherein a wall thickness of at least one of the at least one inner intermediate walls running in the width direction is greater than the wall thickness of the two outer intermediate walls, and
wherein the at least one inner intermediate wall with the greater wall thickness has the greater wall thickness merely in a longitudinal end portion of the tube body on the end side in the longitudinal direction.
