Abstract
Description
Technical Field
[0001] The utility model relates to a double-circuit combined electric heating tube. Background Art
[0002] There are often some technical defects in traditional electric heating tube products, which may lead to performance degradation, shortened service life and quality problems. Some common problems include:
[0003] The current is too large or unstable: In traditional electric heating tubes with a single current of up to 13.63A, the current may be too large or unstable, resulting in broken wires and no power. At the same time, there may be safety hazards such as dry burning due to lack of water, bursting tubes and leakage, which seriously affect the reliability and safety of the equipment.
[0004] Short service life: The service life of traditional electric heating tubes is usually only about 2 years, and they need to be replaced and repaired under normal conditions, which not only increases maintenance costs, but also affects the continuous operation efficiency of the equipment.
[0005] Poor quality of pipe bending: The pipe bending machines used in traditional production processes may cause problems such as strain on the pipe surface and loose magnesium powder, which will affect the quality and durability of the pipe. Quality problems such as poor internal heat dissipation, pipe bursting, and pipe surface breakdown may occur during use, which in turn affects the stability and reliability of the equipment. Utility Model Content
[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a double-loop combined electric heating tube which can reduce the phenomena of wire breakage, dry burning due to lack of water, tube bursting and leakage caused by excessive or unstable current during use, and greatly reduce the phenomena of tube surface strain and magnesium powder loosening during tube bending.
[0007] The technical solution adopted by the utility model to solve its technical problems is:
[0008] A double-loop combined electric heating tube includes a first loop tube, a second loop tube adjacent to the first loop tube, and an electric connector connected to the ends of the first loop tube and the second loop tube. The first loop tube includes a first U-shaped section, a first bending section integrally formed with the first U-shaped section, a first loop section integrally formed with the first bending section, and a second U-shaped section integrally formed with the first loop section. The second loop tube includes a third U-shaped section, a third bending section integrally formed with the third U-shaped section, a second loop section integrally formed with the third bending section, and a fourth U-shaped section integrally formed with the second loop section.
[0009] Preferably, the first return-shaped segment and the second return-shaped segment form an angle of 90°.
[0010] Preferably, a 180° bend is formed between the first U-shaped section and the first bending section.
[0011] Preferably, a 180° bend is formed between the first bending section and the first return section.
[0012] Preferably, the first U-shaped segment and the first circular segment overlap each other.
[0013] Preferably, the first U-shaped segment and the second U-shaped segment are overlapped with each other.
[0014] Preferably, a 180° bend is formed between the third U-shaped segment and the third bending segment.
[0015] Preferably, a 180° bend is formed between the third bending section and the second loop section.
[0016] Preferably, the third U-shaped segment and the second circular segment overlap each other.
[0017] Preferably, the third U-shaped segment and the fourth U-shaped segment are overlapped with each other.
[0018] The beneficial effects of the utility model are:
[0019] The working current is reduced. The original single-branch current of 13.63A is optimized to 6.81A for the double-circuit combination, which greatly reduces the phenomenon of broken wire (no power) and dry burning due to lack of water, tube bursting and leakage caused by excessive or unstable current during use. The service life before optimization can only reach about 2 years under normal conditions, and the service life after optimization can reach more than 3 years under normal use conditions.
[0020] This product uses our company's latest computer-programmed six-axis servo motor advanced tube bending machine to bend the tube, with accurate size and uniform speed. It greatly reduces the phenomenon of tube surface scratches and magnesium powder loosening during tube bending, thereby avoiding the occurrence of quality problems such as tube explosion and tube surface breakdown due to poor internal heat dissipation during the warranty period.

[0027] See also Figure 1-3 As shown, a double-loop combined electric heating tube includes a first loop tube 1, a second loop tube 2 arranged adjacent to the first loop tube 1, and an electric connector 3 connected to the ends of the first loop tube 1 and the second loop tube 2. The first loop tube 1 includes a first U-shaped section 11, a first bending section 12 integrally formed with the first U-shaped section 11, a first loop section 13 integrally formed with the first bending section 12, and a second U-shaped section 14 integrally formed with the first loop section 13.

[0028] By optimizing the single current from 13.63A to 6.81A per branch, the problems caused by excessive or unstable current, such as broken wire, no power, dry burning due to lack of water, etc., are effectively reduced, thereby improving the safety and stability of the equipment; the optimized double-circuit combination electric heating tube can reach a service life of more than 3 years under normal use, compared with the traditional electric heating tube of about 2 years, which extends the service life, reduces the frequency of replacement and maintenance, and saves maintenance costs.
[0029] The latest computer-programmed six-axis servo motor advanced tube bending machine is used for tube forming, which has accurate size and uniform speed, effectively reducing the occurrence of quality problems such as tube surface scratches and loose magnesium powder during tube bending, and improving the quality and durability of the tube.
[0030] The original single current is divided into two currents, each current is halved, which reduces the working current of the entire electric heating tube, thereby reducing the problems caused by excessive or unstable current; the optimized double-circuit combined electric heating tube has a more compact structure and higher heat dissipation efficiency, which helps to reduce the problem of poor internal heat dissipation and reduces the incidence of quality problems such as tube burst and tube surface breakdown.
[0031] The first return-shaped segment 13 and the second return-shaped segment 23 form an angle of 90°, the first U-shaped segment 11 and the first bending segment 12 form a 180° bend, the first bending segment 12 and the first return-shaped segment 13 form a 180° bend, the first U-shaped segment 11 and the first return-shaped segment 13 overlap each other, and the first U-shaped segment 11 and the second U-shaped segment 14 overlap each other.
[0032] By forming a 90° angle between the first return section 13 and the second return section 23, and overlapping the first U-shaped section 11 and the first return section 13, and overlapping the first U-shaped section 11 and the second U-shaped section 14, this layout can utilize space more effectively, is particularly suitable for installation needs in limited space, and improves the compactness and space utilization of the overall system.
[0033] The 180° bend design and the upper and lower overlapping settings can increase the structural stability of the piping system, reduce the possibility of vibration and deformation, and thus extend the service life of the electric heating tube; the design of the 90° angle and 180° bend may affect the flow pattern of the fluid in the pipeline, help reduce the speed and pressure of the fluid, reduce energy loss, and improve the efficiency of the system.
[0034] The overlapping arrangement and 180° bend are probably based on the principles of structural engineering. Through reasonable layout and connection methods, the stability and structural strength of the system are increased. Through special configuration design, the pipeline system can be arranged more compactly in a limited space, while ensuring the function and performance of the system.
[0035] The third U-shaped section 21 and the third bending section 22 form a 180° bend, the third bending section and the second return section 23 form a 180° bend, the third U-shaped section 21 and the second return section 23 overlap each other, and the third U-shaped section 21 and the fourth U-shaped section 24 overlap each other.
[0036] The up-and-down overlapping setting and the 180° bending design can make more effective use of space, improve the compactness and space utilization of the overall system, and are especially suitable for installation needs in limited spaces. The 180° bending design and the up-and-down overlapping setting help increase the structural stability of the piping system, reduce the possibility of vibration and deformation, and thus extend the service life of the system.
[0037] The overlapping arrangement and 180° bend may be based on the principles of structural engineering. Through reasonable layout and connection methods, the stability and structural strength of the system are increased. This is proposed after considering the efficiency of space utilization. Through special configuration design, the pipeline system can be arranged more compactly in a limited space, while ensuring the function and performance of the system.
