Description

Technical Field

[0001] This utility model belongs to the field of temperature compensation technology, and in particular relates to a heat tracing device for new energy heating pipelines. Background Technology

[0002] In new energy heating systems, heating pipelines are a crucial link in heat transfer, and their stable operation directly affects the efficiency and reliability of the entire heating system. However, in cold regions or low-temperature environments, heating pipelines are prone to internal water freezing or insufficient heating due to excessively low temperatures, severely affecting the heating effect and potentially causing pipeline damage and system failure.

[0003] Traditional methods of heat supply pipeline insulation rely primarily on the design of the pipeline's own insulation layer. However, this method often fails to meet insulation requirements under extreme low-temperature conditions. To address this issue, the industry has begun using electric heat tracing technology to provide auxiliary heating for heat supply pipelines. Electric heat tracing technology involves laying electric heating tape along the pipeline, converting electrical energy into heat energy to directly heat the pipeline, thereby effectively preventing pipeline freezing and improving heating efficiency.

[0004] However, existing electric heat tracing devices still have some shortcomings in application. On the one hand, traditional electric heat tracing devices often have few temperature monitoring points and inaccurate temperature pickup, making it impossible to quickly adjust the working state of the heat tracing cable according to the actual temperature of the pipeline, resulting in insufficient matching between electric heat tracing devices and new energy heating systems.

[0005] The installation location and method of the temperature sensor may also affect the accuracy of temperature monitoring, and thus the control effect of the heat tracing cable.

[0006] To address the aforementioned problems, it is particularly important to develop a new energy heating pipeline heat tracing device that can intelligently monitor pipeline temperature, automatically adjust the working status of the heat tracing cable, and is easy to install and highly adaptable. The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this utility model is to provide a heat tracing device for new energy heating pipelines. Through the staggered arrangement of electric heating modules and temperature monitoring modules, combined with an intelligent temperature control system, it can realize real-time monitoring of pipeline temperature and automatic adjustment of the heat tracing cable. It has the characteristics of rapid heat replenishment, high efficiency and energy saving, convenient installation and strong adaptability, effectively improving the reliability and stability of the heating system.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a heat tracing device for a new energy heating pipeline, comprising a temperature controller, a relay switch, and an electric heating module and a temperature monitoring module arranged alternately on the outside of the heating pipeline. The electric heating module includes a heat-conducting film layer, an electric heating tape, and an insulation layer arranged sequentially from the inside out. Several electric heating tapes are connected to the relay switch via wires. The temperature monitoring module includes a temperature sensor and a sensor mounting strap. The sensor mounting strap is fixedly installed on the outer wall of the heating pipeline, and the temperature sensor is inserted between the sensor mounting strap and the outer wall of the heating pipeline. Several temperature sensors are connected to the temperature controller via wires. The temperature controller is connected to the relay switch.

[0009] As a preferred technical solution of this utility model, the heat-conducting film layer is made of copper foil or aluminum foil, which has good thermal conductivity and can quickly conduct the heat generated by the electric heating tape to the heating pipe.

[0010] As a preferred technical solution of this utility model, the electric heating cable is spirally wound on the heat-conducting film layer. This design can increase the contact area between the electric heating cable and the heat-conducting film layer and improve the heat conduction efficiency.

[0011] As a preferred embodiment of this utility model, the sensor mounting strip includes a strip; two through holes are symmetrically opened at one end of the strip, and two pairs of mushroom-shaped nails are fixedly arranged on the outer surface near the end of the strip; a pair of tightening strips are symmetrically arranged at the other end of the strip, and a row of positioning holes that cooperate with the mushroom-shaped nails are opened on the tightening strips; a rectangular through hole for mounting the temperature sensor is opened in the middle of the strip; a tightening cover is integrally formed on the outer wall of the strip and disposed above the rectangular through hole, and one end of the tightening cover communicates with the rectangular through hole. This design facilitates the installation and fixation of the temperature sensor, and at the same time protects the temperature sensor from the influence of the external environment.

[0012] As a preferred technical solution of this utility model, the sensor mounting strip is made of rubber, which has good elasticity and corrosion resistance, can adapt to heating pipelines of different diameters, and ensure long-term stable operation.

[0013] This utility model has the following beneficial effects: When any temperature sensor in the temperature monitoring module detects that the temperature of the heating pipe is lower than the set value, the temperature controller can quickly control the relay switch to turn on, so that all electric heating tapes can start heating synchronously. Under the thermal conductivity of the heat-conducting film layer, heat is quickly transferred to the heating pipe, indirectly heating the water inside, realizing rapid heat replenishment when the new energy heating is insufficient, and ensuring the stable operation of the heating system.

[0014] The electric heating cable of this invention is spirally wound on the heat-conducting film layer, which increases the contact area between the electric heating cable and the heat-conducting film layer, thereby improving the heat conduction efficiency and enabling heat to be transferred to the heating pipeline more quickly and evenly.

[0015] This utility model's sensor mounting strip is made of rubber, possessing excellent elasticity and corrosion resistance, and can adapt to heating pipes of different diameters. Its unique design makes the installation and fixing of the temperature sensor simple and quick, while protecting the temperature sensor from external environmental influences.

[0016] This invention achieves automatic monitoring and regulation of heating pipeline temperature through the cooperation of a temperature controller and a relay switch. When the pipeline temperature reaches the set range, the electric heating tape automatically stops working, avoiding energy waste and improving energy utilization efficiency.

[0017] This utility model of heat tracing device can effectively solve the problems of freezing or insufficient heating that may occur in heating pipelines in low-temperature environments, improve the reliability and stability of the heating system, and ensure the normal operation of new energy heating systems in cold regions.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Specific Implementation Example 1: Please refer to... Figure 1-6 As shown, this utility model is a heat tracing device for a new energy heating pipeline, including a temperature controller 1, a relay switch 2, and electric heating modules and a temperature monitoring module arranged alternately on the outside of the heating pipeline. The electric heating module includes a heat-conducting film layer 3, an electric heating tape 4, and an insulation layer 5 arranged sequentially from the inside out. Several electric heating tapes 4 are connected to the relay switch 2 via wires. The temperature monitoring module includes a temperature sensor 6 and a sensor mounting strap 7. The sensor mounting strap 7 is fastened to the outer wall of the heating pipeline, and the temperature sensor 6 is inserted between the sensor mounting strap 7 and the outer wall of the heating pipeline. Several temperature sensors 6 are connected to the temperature controller 1 via wires. The temperature controller 1 is connected to the relay switch 2.

[0029] The heat-conducting film layer 3 is made of copper foil or aluminum foil, which has good thermal conductivity and can quickly conduct the heat generated by the electric heating tape 4 to the heating pipe. It also has the function of balancing the heat and preventing localized high temperatures in the electric heating tape 4.

[0030] The electric heating cable 4 is spirally wound on the heat-conducting film layer 3. This design can increase the contact area between the electric heating cable 4 and the heat-conducting film layer 3 and improve the heat conduction efficiency.

[0031] In practical applications, when one of the temperature sensors 6 detects that the temperature of the heating pipe is lower than the set temperature, it immediately transmits the temperature signal to the temperature controller 1. Upon receiving the signal, the temperature controller 1 quickly controls the relay switch 2 to turn on, causing all the electric heating tapes 4 to start heating synchronously. Under the rapid heat conduction of the heat-conducting film layer 3, the heat generated by the electric heating tapes 4 is quickly transferred to the heating pipe, indirectly heating the water inside, thereby quickly supplementing heat when the new energy heating is insufficient, ensuring the stable operation of the heating system.

[0032] The sensor mounting strip 7 includes a strip 71. Two through holes 72 are symmetrically formed at one end of the strip 71, and two pairs of mushroom-shaped staples 73 are fixedly mounted on the outer surface near the end of the strip 71. A pair of tightening strips 74 are symmetrically formed at the other end of the strip 71, and a row of positioning holes 75 are formed on the tightening strips 74 to mate with the mushroom-shaped staples 73. A rectangular through hole 76 for mounting the temperature sensor 6 is formed in the middle of the strip 71. A tightening cover 77 is integrally formed on the outer wall of the strip 71, positioned above the rectangular through hole 76, and one end of the tightening cover 77 communicates with the rectangular through hole 76. This design facilitates the installation and fixation of the temperature sensor 6, while protecting the temperature sensor 6 from external environmental influences.

[0033] Among them, the sensor mounting strip 7 is made of rubber, which has good elasticity and corrosion resistance, can adapt to heating pipelines of different diameters, and ensure long-term stable operation.

[0034] One specific application of this embodiment is that, in a new energy heating system in a cold region, after installing this new energy heating pipeline heat tracing device, the problem of freezing or insufficient heating of the heating pipeline in a low-temperature environment can be effectively solved, thereby improving the reliability and energy utilization efficiency of the heating system.
