Description

TECHNICAL FIELD

[0001] The utility model relates to drawing table technical field, concretely is a kind of steam generator radiating pipe of high temperature resistance. BACKGROUND

[0002] The existing radiating pipe is directly cooled through pipe wall, and the heat conduction surface area between the radiating pipe and the external environment is limited by the direct cooling through pipe wall, so the heat dissipation capacity of the radiating pipe is limited. In a high-temperature environment requiring a large amount of heat dissipation, direct cooling through the pipe wall may not meet the heat dissipation requirement. For example, a "radiating pipe" is disclosed in Chinese Patent No. 201920624331.0. The device includes an inner pipe and an outer pipe. A plurality of connecting plates are arranged on the outer side wall of the inner pipe and uniformly distributed around the inner pipe. The outer pipe is connected to the inner pipe through the connecting plates. A plurality of fins are arranged on the inner side wall of the outer pipe and uniformly distributed along the circumferential side wall of the inner pipe. The outer pipe protects the fins and reduces the possibility of the fins being impacted, so that the fins can stably play a heat dissipation role. In addition, the connecting plates and the outer pipe increase the contact area with air and improve the overall heat dissipation effect of the radiating pipe. However, during use, heat is transferred away from the outer wall of the inner pipe. In a high-temperature environment requiring a large amount of heat dissipation, heat dissipation through the outer wall of the inner pipe may not meet the heat dissipation requirement. SUMMARY

[0003] To overcome the shortcomings of the prior art, the utility model provides a steam generator radiating pipe with high temperature resistance. The inner layer made of aluminum oxide has good thermal conductivity, which can effectively transfer the heat in the steam to the rest of the inner pipe. The bearing layer made of niobium alloy has a very high melting point and mechanical strength, which can maintain structural stability at high temperatures and withstand pressure and steam impact. The filling layer made of graphene can significantly improve the heat conduction performance of the radiating pipe and further enhance the strength of the inner pipe. The insulating layer made of ceramic fiber can effectively reduce the heat exchange between the inner pipe and the surrounding environment, thereby preventing external heat from entering the inner pipe and improving the heat dissipation efficiency. The outer layer made of ceramic can provide good corrosion resistance and wear resistance, protecting the radiating pipe from corrosion and physical damage in the environment. The heat-conducting fins fixed on the side of the inner layer send heat out from the inside to the outside, increasing the heat conduction path and improving the heat conduction efficiency. The outer pipe can receive the temperature on the heat-conducting fins and dissipate heat through the honeycomb heat dissipation holes. The honeycomb-shaped heat dissipation holes effectively increase the heat exchange surface, allowing more heat to be released from the outer pipe, enhancing the overall heat dissipation effect and enabling a large amount of heat to be effectively dissipated to the surrounding environment in a shorter time.
