Abstract

The invention provides a rectangular transverse-section finned tube. The finned tube comprises a base tube and transverse fins arranged on the base tube, wherein the base tube and the transverse fins are rectangular. According to the finned tube, by arranging the rectangular fins and the rectangular base tube, the base tube and the fins have the same shape, the heat exchange field can be synergetic, the heat distribution direction and the transmission amount can be basically identical in the circumferential direction, and therefore heat transfer can be further improved.

Description

technical field

[0001] The invention belongs to the field of heat exchangers, in particular to a heat exchanger part-finned tube. Background technique

[0002] With the rapid development of modern society and economy, the human demand for energy is increasing. However, the reserves of traditional energy such as coal, oil, and natural gas continue to decrease and become increasingly scarce, resulting in rising prices. At the same time, the environmental pollution caused by conventional fossil fuels is also becoming more and more serious. These greatly limit the development of society and the improvement of human life quality. . Therefore, in order to save energy, enhanced heat transfer technology is constantly developing, and finned tubes are also widely used in the field of heat exchange. At present, the fins in the prior art are all arranged on the base tube as a whole. Therefore, although the use of finned tubes has the function of enhancing heat transfer, under certain ...

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...
