Embodiment Construction
[0030] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0031] The invention discloses a finned tube. The finned tube includes a base tube and transverse fins arranged on the base tube. The cross section of the base tube is rectangular, and the shape of the fins is rectangular.
[0032] By arranging rectangular fins and rectangular base tubes, the base tubes and fins have the same shape, so that the heat exchange field is coordinated, and the heat distribution direction and the amount of heat transfer are basically the same in the circumferential direction, thereby further enhancing heat transfer.
[0033] As a preference, figure 1 A schematic cross-sectional view of an H-shaped finned tube is shown. Such as figure 1 As shown, the H-shaped finned tube includes a base tube 1 and fins 4, 5, the fins 4, 5 are multiple groups, and the multiple groups of fins 4, 5 are along the axis direction of t...
