Description

Technical Field

[0001] The utility model relates to an electromagnetic heating tube. Background Art

[0002] Heating water is a common and important need in industrial and domestic applications. Traditional water heating technologies usually rely on resistance heating or burning fuel. Although these methods are widely used, they have problems such as low efficiency, complex equipment maintenance, and environmental pollution. For example, resistance heaters convert electrical energy directly into thermal energy, which has limited efficiency, and the life and performance of resistance wires will be affected at high temperatures. At the same time, combustion heaters will produce harmful gases during the combustion process, posing a threat to the environment and human health.

[0003] In the prior art, there are instant water heaters, which heat water immediately when it flows through the water heater to provide hot water. Instant water heaters generally use electric heating elements, such as heating wires or heating tubes, to directly heat the water flowing through. Although this design is simple in structure, it is easy to cause low heat transfer efficiency and large energy waste because the electric heating element is in direct contact with water. Utility Model Content

[0004] The utility model aims to provide an electromagnetic heating tube with high energy utilization rate and fast response speed.

[0005] The purpose of the utility model is achieved in this way:

[0006] An electromagnetic heating tube comprises a hollow magnetic conductive tube for water to pass through, a heat preservation and insulation layer, an insulating layer and an electromagnetic coil.

[0007] The thermal insulation layer is arranged on the periphery of the hollow magnetic conductive tube;

[0008] The insulating layer is arranged on the periphery of the thermal insulation layer;

[0009] The electromagnetic coil is wound on the insulating layer;

[0010] The electromagnetic coil is energized to generate a changing magnetic field that penetrates the hollow magnetic tube and induces eddy currents. The eddy currents in the hollow magnetic tube generate heat due to the resistance of the metal to heat the water passing through the hollow magnetic tube.

[0011] High-efficiency heating: The electromagnetic coil generates heat directly in the water channel by generating a changing magnetic field, inducing eddy currents in the hollow magnetic tube. This heating method has almost no energy loss because the heat is generated directly in the water flow, and the thermal efficiency is greatly improved compared to traditional heating elements.

[0012] Fast response: Electromagnetic induction heating can achieve almost instant heating effect, which makes the system respond quickly and can quickly adjust the heating temperature and intensity to meet different usage requirements. This is especially beneficial for industrial applications that require fast heating.

[0013] Improve energy utilization: Due to the directness and high efficiency of electromagnetic heating, the energy utilization of the entire system is significantly improved. This not only reduces energy consumption, but also helps to reduce operating costs and reduce environmental impact.

[0014] Good thermal insulation effect: Setting a thermal insulation layer around the hollow magnetic tube can effectively reduce the loss of heat energy during the transmission process. Good thermal insulation performance not only further improves energy efficiency, but also ensures the stable operation of the heating system in a low temperature environment.

[0015] The purpose of the utility model can also be solved by the following technical measures:

[0016] Furthermore, the insulating layer includes a hollow mica tube, the hollow magnetic tube is placed in the hollow mica tube, the hollow magnetic tube and the hollow mica tube form a filling gap, and the filling gap is filled with thermal insulation cotton and heat insulation cotton to form the thermal insulation layer.

[0017] Enhanced insulation performance: Mica, as a natural insulating material, has extremely high electrical insulation and heat resistance. Using hollow mica tubes as an insulating layer can effectively prevent the current generated by the electromagnetic coil from directly contacting any conductive material, thereby improving the safety and stability of the entire system.

[0018] Reduce heat loss: The thermal insulation cotton and heat-insulating cotton filled between the hollow magnetic tube and the hollow mica tube can significantly reduce the loss of heat energy. This structural design optimizes the heat retention effect, ensures the thermal efficiency during the heating process, and helps maintain the water temperature and reduce energy consumption.

[0019] Improve overall structural strength: The hollow mica tube not only provides excellent insulation performance, but also enhances the mechanical strength of the overall structure. The physical stability of the mica tube protects the internal metal tube from direct impact from the external environment, such as physical impact or chemical corrosion, thereby extending the service life of the equipment.

[0020] Strong environmental adaptability: Due to the good chemical stability of mica, the hollow mica tube can withstand the erosion of different chemicals. This makes the electromagnetic heating tube suitable for a variety of environments, including industrial applications where corrosive substances may exist.

[0021] Improved energy efficiency: By combining the insulation of the mica tubes with the thermal insulation effect of the filling material, the energy efficiency of the entire system is further improved.

[0022] Furthermore, the insulating layer also includes a hollow plastic bracket, the outer wall of the hollow plastic bracket is provided with wire grooves at intervals along its length direction, the hollow mica tube is placed in the hollow plastic bracket, and the wire core of the electromagnetic coil is sleeved on the corresponding wire groove.

[0023] Enhanced structural stability: As part of the insulation layer, the hollow plastic bracket provides additional support and structural stability for the entire system. The bracket can effectively fix and support the hollow mica tube, reducing the risk of deformation and damage caused by temperature changes or external forces.

[0024] The layout of the electromagnetic coil is more stable: the design of the hollow plastic bracket allows the wire core of the electromagnetic coil to be placed in the wire groove on the bracket. This layout ensures the stable fixation of the electromagnetic coil, preventing it from shifting or shaking, thereby ensuring the stability and reliability of the heating process.

[0025] Improved electrical safety: As part of the insulation layer, the hollow plastic bracket can effectively isolate the electromagnetic coil and other conductive parts, reducing the probability of electrical safety accidents. The insulation performance of the bracket ensures the stable operation of the electromagnetic heating system and the safe use of users.

[0026] Improve the overall durability of the system: The hollow plastic bracket has good corrosion resistance and wear resistance, and can work stably for a long time under harsh environmental conditions. This durability enhances the overall reliability and service life of the electromagnetic heating tube and reduces maintenance and replacement costs.

[0027] Optimize heating effect: The use of brackets not only helps to maintain a stable layout of the electromagnetic coils, but also optimizes the heating effect. By correctly arranging the electromagnetic coils, more uniform and efficient heating can be achieved, improving the quality of heated water and the accuracy of temperature control.

[0028] Furthermore, the hollow magnetic conductive tube is a hollow metal tube.

[0029] The beneficial effects of the utility model are as follows:

[0030] The utility model utilizes electromagnetic coils to generate a changing magnetic field and directly heats the water flow through eddy currents. This heating method is more efficient than traditional electric heating wires because it can directly convert electrical energy into thermal energy, reducing energy loss. In addition, this method does not require direct contact between the heating element and the water, thereby reducing energy loss and improving heating efficiency, providing a more efficient, more economical and more reliable instant hot water solution.

[0031] The utility model can achieve almost instant heating effect by electromagnetic induction heating, which makes the system respond quickly and can quickly adjust the heating temperature and intensity to meet different usage requirements. This is particularly beneficial for industrial applications that require rapid heating.

[0032] In the utility model, mica, as a natural insulating material, has extremely high electrical insulation and heat resistance. Using the hollow mica tube as an insulating layer can effectively prevent the current generated by the electromagnetic coil from directly contacting any conductive material, thereby improving the safety and stability of the entire system.

[0033] In the utility model, the heat preservation cotton and thermal insulation cotton filled between the hollow magnetic tube and the hollow mica tube can significantly reduce the loss of heat energy. This structural design optimizes the heat retention effect, ensures the thermal efficiency during the heating process, and helps maintain the water temperature and reduce energy consumption.

[0034] The design of the hollow plastic bracket of the utility model allows the wire core of the electromagnetic coil to be sheathed in the wire groove on the bracket. This layout ensures the stable fixation of the electromagnetic coil and prevents it from shifting or shaking, thereby ensuring the stability and reliability of the heating process.
