Description

Technical Field

[0002] The working principle of the one-way heat transfer electric heating tape is based on the thermal effect of electric current. That is, when the current passes through the conductor, heat is generated due to the collision between the electrons and the atomic nuclei inside the conductor. In the one-way heat transfer electric heating tape, this heat is generated by the heating wire and transferred along a specific direction (one-way) to provide heat for the object that needs to be kept warm or heated. However, if the temperature of the electric heating tape is too high or too low, it may cause safety hazards, such as equipment failure and personal injury. For example, the Chinese patent discloses "a one-way heat transfer electric heating tape", and its application number is: "20192113 2918.6", which is provided with a rain curtain, which facilitates the installation of the fixing base a and the fixing base b on the pipe to be installed on the electric heating cable body through four fixing rings. After the electric heating cable body is installed, the rain curtain is pulled from the left side of the fixing base a to the right side of the fixing base b, and the fixing rod is inserted into the fixing hole to stabilize the rain curtain, which helps to prevent rain from interfering with the electric heating cable body. However, the electric heating cable has no stable monitoring measures, and the electric heating cable may be damaged by overheating, or even cause safety accidents such as fire.

[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] Reference Figure 1-4The embodiment of the utility model is a one-way heat transfer electric heating tape, which includes: a busbar 1, which serves as the main current carrier of the electric heating tape. The side surface of the busbar 1 is provided with an insulating layer 2, which covers the surface of the busbar to provide electrical insulation, prevent current leakage or short circuit, and ensure safe use. The insulating layer 2 is formed of a rubber material. The side surface of the insulating layer 2 is provided with a heating wire 3, which is used to generate heat when current passes through. It is the main heating element of the electric heating tape. The heating wire 3 is wound around the side of the busbar 1 and the insulating layer 2 to ensure that the heat can be evenly distributed. The side surface of the heating wire 3 is provided with an inner sheath 4, which is wrapped around the outside of the heating wire 3 to provide additional protection and support to prevent the heating wire 3 from being directly exposed to the external environment. At the same time, it serves as a supporting structure for the temperature sensor 12. The heating wire 3 is wound around the side of the busbar 1 and the insulating layer 2, and is located at the center of the inner sheath 4.

[0023] A plurality of temperature sensors 12 are fixedly connected to the upper surface of the inner sheath 4 for monitoring the temperature of the electric heating tape to ensure that the temperature is controlled within a safe and effective range. A sensing wire 11 is fixedly connected to the side surface of the temperature sensor 12 for connecting the temperature sensor and the control system to transmit the temperature signal for temperature regulation. A limiting groove 13 is provided on the upper surface of the inner sheath 4 for fixing the temperature sensor and the sensing wire to ensure that their position is stable to prevent movement or damage during use. The temperature sensor 12 and the sensing wire 11 are both located inside the limiting groove 13. A woven mesh 5 is provided on the side surface of the inner sheath 4 for covering the outer side of the inner sheath 4, the temperature sensor 12, the sensing wire 11 and the limiting groove 13 to provide electromagnetic shielding and additional mechanical strength to enhance the overall durability and safety of the electric heating tape. The woven mesh 5 is made of metal and covers the temperature sensor 12, the sensing wire 11 and the limiting groove 13.

[0024] The side surface of the woven mesh 5 is provided with an outer sheath 6, which is used as the outermost protective structure. The outer sheath 6 provides comprehensive protection to prevent the external environment from eroding and damaging the internal components. The side surface of the outer sheath 6 is provided with a waterproof layer 8. The waterproof layer 8 is formed by applying a waterproof paint to prevent moisture from invading the interior of the electric heating cable and ensure its normal operation in a humid environment. The side surface of the waterproof layer 8 is provided with an anti-ultraviolet layer 9. The anti-ultraviolet layer 9 is composed of polyvinyl chloride (PVC) to resist ultraviolet radiation and aging effects and extend the service life of the electric heating cable. The side surface of the anti-ultraviolet layer 9 is provided with a wear-resistant layer 10. The wear-resistant layer 10 is composed of carbon fiber to resist friction and wear from external objects and further protect the electric heating cable. An elastic band 7 is fixedly connected to the upper surface of the outer sheath 6. The elastic band 7 passes through the waterproof layer 8, the anti-ultraviolet layer 9, and the wear-resistant layer 10 to ensure that the electric heating cable can fit tightly on the object to be heated to avoid displacement, while increasing the flexibility and adaptability of the electric heating cable.

[0025] Working principle: fit the electric heating tape to the pipe that needs to be heated, and the elastic band 7 can provide a fixed position, which makes it convenient to use the rolled tape to fix the electric heating tape to avoid its deviation, ensure that the electric heating tape is closely fitted to the heated object (such as a pipe), and improve the heating efficiency. The insulating layer 2 on the side surface of the busbar 1 is formed of a rubber material, which has good insulation performance and weather resistance, and can prevent current leakage and erosion by the external environment. When current passes through the heating wire 3, the heating wire 3 will generate heat due to its certain resistance. The heat is then gradually transferred outward through the layered structure of the inner sheath 4, the braided mesh 5, the outer sheath 6, etc., and finally heats the heated object (such as a pipe). At the same time, the temperature sensor 12 is fixed on the upper surface of the inner sheath 4 and is located inside the limit groove 13 to ensure that it can stably and accurately monitor the real-time temperature of the electric heating tape, and the temperature sensor 12 and the sensing line 11 are both made of the braided mesh 5. Cover to ensure its stable installation. The woven mesh 5 is made of metal, which provides good electromagnetic shielding and mechanical strength to protect the electric heating tape from interference and damage from the external environment. When the temperature reaches the preset upper limit, the temperature sensor transmits a signal to the control system through the sensor line 11. The control system adjusts the current or turns it on and off according to the received signal, thereby controlling the heating power of the heating wire and realizing precise temperature control. The outer sheath 6 serves as the outermost protective structure to resist erosion and wear from the external environment. The waterproof layer 8 thereon is formed by applying a waterproof coating to prevent moisture from invading the interior of the electric heating tape. The anti-ultraviolet layer 9 is made of polyvinyl chloride (PVC) to resist ultraviolet radiation and aging, and protect the electric heating tape from damage by direct sunlight. The wear-resistant layer 10 is made of carbon fiber, which has excellent wear resistance and mechanical strength, resists friction and wear from external objects, and further extends the service life of the electric heating tape.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
