Description

Technical Field

[0001] This utility model belongs to the field of electric heating, specifically, it relates to an aerogel combined with an electric heat tracing device. Background Technology

[0002] In many industrial and civil fields, there are high requirements for the insulation and temperature maintenance of equipment such as pipelines and tanks. Electric heat tracing is mainly used in the following aspects: 1. Insulation: In some applications with strict temperature requirements, the temperature must be kept constant within a certain range to prevent fluctuations. When the insulation layer cannot meet these requirements, electric heat tracing can effectively achieve this purpose. 2. Anti-condensation: During pipeline transportation, as the ambient temperature decreases, heat loss from the medium inside the pipeline can cause the medium temperature to drop below its freezing point, resulting in condensation. Electric heat tracing can keep the medium above its freezing point. 3. Freezing prevention: During outdoor pipeline transportation, especially in cold northern winter regions, as the temperature decreases and time increases, the effectiveness of the insulation layer gradually reduces. For liquid media such as water and milk, the temperature can drop to its freezing point. Electric heat tracing can maintain the temperature above the freezing point, ensuring a safe temperature.

[0003] Traditional insulation materials such as rock wool and polyurethane foam offer some insulation benefits, but suffer from limitations such as limited insulation performance, large volume, and susceptibility to moisture. Aerogel, as a novel insulation material, boasts advantages such as extremely low thermal conductivity, high porosity, and low density, exhibiting superior performance in thermal insulation. However, aerogel insulation alone cannot meet the needs of scenarios requiring active heating to maintain a specific temperature. Electric heat tracing technology converts electrical energy into heat energy to heat equipment and ensure its temperature remains within a set range; however, traditional electric heat tracing systems have shortcomings in heat loss control, resulting in high energy consumption. Therefore, combining aerogel with electric heat tracing can fully leverage the advantages of both, improving insulation and heating efficiency while reducing energy consumption. Utility Model Content
