A cylindrical member for cooling and heating comprises: a plate-like section body (1) bending around an axis to form a cylinder. Two end surfaces of the plate-like section body (1) are welded and fixed. The plate-like section body (1) is provided with a fluid channel group formed by a plurality of through holes (2) parallel along the axis, and the fluid channel group is provided with a fluid channel group inlet (3) and a fluid channel group outlet (4), such that the member improves cooling effect, facilitates processing, and reduces processing costs and material costs. When cylinder wall thicknesses are the same, stiffening of an entire member is increased, thus using a simple bending mold to complete processing by stretching out a corresponding section. |
