Description

Technical Field

[0001] This utility model belongs to the field of thermal pipeline technology, specifically, it relates to a silicon core lubricated composite thermal pipe. Background Technology

[0002] Traditional heating pipelines often employ a single-material structure, resulting in problems such as low thermal conductivity, weak deformation resistance, and poor corrosion resistance. For example, while steel wire mesh reinforced composite pipes improve compressive strength through steel wire reinforcement, the inner polyethylene material is prone to aging at high temperatures. HDPE three-layer co-extruded pipes, although improving performance through a multi-layer structure, suffer from interlayer bonding strength limited by material compatibility. Furthermore, existing pipelines experience increased internal wall friction resistance during long-term high-temperature operation, leading to decreased energy efficiency, and lack self-lubricating properties, increasing maintenance costs.

[0003] The utility model disclosed in CN223218757U provides a silicon core tube with a thermal insulation layer, comprising a silicon core tube body and a thermal insulation sleeve fitted onto the outer wall of the silicon core tube body. The thermal insulation sleeve contains multiple thermal insulation channels arranged annularly around the axis of the silicon core tube body, and each thermal insulation channel contains multiple thermal insulation cavities, which are spaced apart along the axis of the silicon core tube body. The silicon core tube with a thermal insulation layer provided by this utility model has a thermal insulation sleeve on the outside of the silicon core tube body. Thermal insulation is achieved through the multiple thermal insulation channels within the sleeve, and each thermal insulation channel contains multiple thermal insulation cavities. This allows the thermal insulation cavity at the damaged location to be isolated by the thermal insulation cavity when the thermal insulation sleeve is damaged by external force, ensuring that the insulation effect remains largely unchanged and does not affect the overall performance of the silicon core tube. This design offers good practicality.

[0004] However, the aforementioned patents still have the following problems: In view of this, this utility model is proposed. Utility Model Content
