Abstract

The invention provides an H-shaped heat exchange pipe which comprises a base pipe and multiple sets of fins. The multiple sets of fins are arranged on the base pipe at intervals in the axis direction of the base pipe, and each set of fins is parallel to the cross section of the base pipe. Each set of fins includes two fins, wherein the two fins are symmetric about the face where the axis of the base pipe is located. The cross section of the base pipe is rectangular. The fins are rectangular. A first opening and a second opening are formed between every two fins, wherein the first opening and the second opening are symmetric about the face where the axis of the base pipe is located. A finned pipe is provided so that the function of heat transfer strengthening can be met, and meanwhile dust accumulation can be relieved to a great extent.

Description

technical field

[0001] The invention belongs to the field of heat exchangers, and in particular relates to a heat exchanger part-H-type heat exchange 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 hea...

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...
