Embodiment Construction

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Such as figure 1 As shown, the high-performance special-shaped toothed spiral fin tube provided in this embodiment includes a base tube 1 and fins 2 arranged on the outer surface of the base tube 1, and the fins 2 are provided with several notches 3 , the edge of the notch 3 is provided with grooves, and the fins 2 are spiral fins.

[0018] Such as figure 2 As shown, the shape of the groove is wavy.

[0019] A plurality of notches 4 are provided on the groove, and the notches are one of semicircle, triangle, rectangle and trapezoid. Such as image 3 As shown, the shape of the notch is trapezoidal.

[0020] The high-performance special-shaped toothed spiral fin tube provided in this embodiment uses a special tool to process the flat steel strip with a certain thickness into teeth of different shapes and angles, and then uses a high-frequency welding process t...

Abstract

The invention discloses a high-performance irregular toothed spiral finned tube which comprises a base tube and fins arranged on the outer surface of the base tube. A plurality of notches are formed in the fins, and grooves are formed in the edges of the notches. The high-performance irregular toothed spiral finned tube has the advantages that the contact area between the side faces of the fins and smoke is increased, accordingly heat exchange is enhanced, and a heat exchange device can achieve the purposes of saving space and cost. Due to the fact that the fins have a certain thickness themselves, turbulent flow produced by the fins and the smoke can be strengthened, and accordingly the purposes of improving the heat exchange efficiency and strengthening the heat transfer effect are achieved. Irregular teeth are machined through a specially-manufactured cutter, so that the high-performance irregular toothed spiral finned tube has the advantages of being few in machining process modification, high in machining efficiency and the like and can meet the large-scale and industrial application requirements.

Description

technical field [0001] The invention belongs to the technical field of industrial waste heat utilization, energy saving and emission reduction, in particular to a high-performance special-shaped toothed spiral fin tube. Background technique [0002] With the increasing shortage of energy resources, how to rationally utilize energy and reduce energy consumption per unit of output value has become an urgent problem to be solved in various production fields, especially high-energy-consuming departments. According to relevant data, my country's energy consumption accounts for 21.5% of the global total, but only creates about 12.3% of the global GDP. The reason is, on the one hand, the high proportion of high-energy-consuming industries in my country's industrial structure; on the other hand, the low level of energy utilization in my country's industrial sector, which is far behind the international advanced level. According to statistics, nearly 50% of industrial energy consump...
