Abstract
A tube for a thermal transfer device can include a wall having a length and having an inner surface and an outer surface, wherein the inner surface forms a cavity. The tube can also include at least one first dimple pressed into the wall toward the cavity at a first location along the length of the wall, where the inner surface of the wall at the at least one first dimple is separated from itself by a first distance. The tube can further include at least one second dimple pressed into the wall toward the cavity at a second location along the length of the wall, where the inner surface of the wall at the at least one second dimple is separated from itself by a second distance. The cavity can be configured to receive a fluid that flows continuously along a length of the at least one wall.
