A curvature/wavy/bubble shaped periodic unevenness is arranged at base (6) and/or the side panel (2) with the fluid in contact. The curved thinner and thicker walls are interconnected at junction points (11a, 11b, 12a, 12b) by welding and arranged to the fluid area. An arrangement comprises an agitator or a pumping device for motion of the fluid along the contact area. The junction points are diagonally arranged to the direction of the fluid motion.
