Abstract

The invention discloses a heating pipe, and the heating pipe consists of an innermost heating body, a central composite layer, and an outermost heat dissipating layer. The central composite layer wraps the heating body, and is wrapped by the heat dissipating layer. The heat dissipating layer employs No.50 engine oil as a solvent, and the components and mass fraction are as follows: 100 parts of ethylene-propylene diene copolymer, 12-14 parts of medroxyprogesterone acetate, 0.4-0.6 parts of sulphur, 5-7.5 parts of dicumyl peroxide, 1-2 parts of stearic acid, 23-27 parts of graphite, 4-6 parts of carbon black, 4-6 parts of Vaseline, 1-2 parts of inhibitor, 1-2 parts of accelerant M, 4-6 parts of zinc oxide, 9-11 parts of polyphenylene sulfide, and 4-6 parts of antimonous oxide. The tensile strength of the heating pipe is greater than 12.5 Mpa, and the break elongation rate of the heating pipe is greater than 150%, thereby enabling the heating pipe to be not liable to be broken, and fully guaranteeing the safety during installation and use. Moreover, the heating pipe is good in heat dissipating efficiency, and the heat conductivity coefficient is 65W / m.K.

Description

technical field [0001] The invention relates to a heating element, in particular to a heating tube. Background technique [0002] At present, in terms of indoor heating, electric heating equipment is more and more popular due to its advantages of simple and intelligent operation, low environmental pollution, and low cost. The heating methods of traditional electric heating equipment mainly include liquid heating and conductor heating. The tubes are heated in two ways. [0003] Liquid heating uses a circulating pump body as the power to make the superconducting heat flow through the radiator continuously, and the superconducting liquid is continuously heated while flowing to realize the circulating heat dissipation of the superconducting liquid. The disadvantage of using liquid heating is that the noise of the pump body is relatively high. Large, especially at night, it is easy to affect people's sleep. After a period of time, the superconducting liquid needs to be added aga...

[0003] Liquid heating uses a circulating pump body as the power to make the superconducting heat flow through the radiator continuously, and the superconducting liquid is continuously heated while flowing to realize the circulating heat dissipation of the superconducting liquid. The disadvantage of using liquid heating is that the noise of the pump body is relatively high. Large, especially at night, it is easy to affect people's sleep. After a period of time, the superconducting liquid needs to be added again to replenish the evaporated part of the superconducting liquid. This is not only time-consuming and laborious, but also not conducive to saving costs, especially the increase of the pump This further increases the cost of heating equipment. When liquid-heated heating equipment is used for floor heating, once the pipeline transporting superconducting liquid breaks, it needs to be demolished and repaired, and the maintenance cost is relatively high.

[0004] Conductor heating tubes mainly use heatable conductive wires. In recent years, with the development of carbon fibers, heating tubes using carbon fibers as conductors have appeared. The diameter of carbon fiber heating tubes is generally 4cm, and the laying of 10m 2 Underfloor heating requires about 100m of carbon fiber heating tubes to achieve the heating effect, so carbon fiber heating tubes are used more, which is also not conducive to cost reduction, and the outer skin covered with carbon fibers is easy to break and cause electric leakage, which poses a great safety hazard
