Embodiment Construction

[0014] Specific embodiments of the present invention are described with reference to the above drawings.

[0015] As can be seen from Fig. 1 and Fig. 2, the manufacturing method of this heat exchanger tube comprises the following steps:

[0016] A. First select non-ferrous metals to make pipes, and divide them into heat exchange area and connection area;

[0017] B. Process a number of raised cooling fins on the surface of the tube heat exchange area;

[0018] C. Cover the outer surface of the heat exchange area with a thermally conductive protective layer.

[0019] The invention adopts non-ferrous metals to make heat exchanging elements. These non-ferrous metals have high thermal conductivity, and at the same time, they do not need to have extremely high heat resistance performance, which not only has good heat conduction effect, but also reduces costs. In addition, these non-ferrous metals also have excellent processing performance, can process more complex surface shapes,...

Abstract

The invention relates to a manufacturing method of a heat exchanger tube and a heat exchanger device; the heat exchanger device comprises a shell (10) and a heat exchanger tube (20); the heat exchanger tube (20) is made of non-ferrous metals, the surface of the heat exchange area (21) of the heat exchanger tube (20) is provided with raised heat radiation fins (23), the outer surface of the heat exchanger tube (20) is covered with a heat conductive insulation thin layer (30) made of inorganic materials. By adopting the technical proposal, the invention improves the traditional heating elements and heating devices, has stable and safe operating condition, prolongs the service life of heating devices, reduces production cost and application cost and enhances heating efficiency by enlarging heat radiating area; the technology can be widely applied to the industries like petroleum, chemical engineering, medicine, food, textile, printing and dyeing, rubber processing, etc.

Description

technical field [0001] The present invention relates to heating equipment, in particular to heating elements and heating devices for heating liquids. Background technique [0002] The liquid heating in the prior art generally uses stainless steel as the heat exchange pipe fittings, especially for corrosive liquids, due to the poor processing performance of stainless steel, the heat dissipation area of ​​this heat exchanger is limited. The thermal efficiency is relatively low and the cost is relatively high. Contents of the invention [0003] The invention provides a method for manufacturing a heat exchanger tube and a heat exchanger based on the heat exchanger tube. The nonferrous metal is used to make the heat exchanger tube, and protruding cooling fins are processed on the surface of the tube to increase The heat dissipation area is improved to improve thermal efficiency. At the same time, a thin heat-conducting and insulating layer of inorganic materials is laid on the...
