[0002] Waste heat power generation systems, as an innovative and efficient energy utilization technology, have been widely used in various industrial fields. These systems primarily utilize waste heat generated during industrial production. Through a series of energy conversion and recycling processes, these previously neglected or wasted heat energy is converted into electricity, thus achieving secondary energy utilization.

[0003] Structurally, a waste heat power generation system consists of several core components: a waste heat collection device, an energy conversion device, a power generation device, and auxiliary systems. The waste heat collection device captures waste heat generated during industrial production and then transmits it to the energy conversion device via waste heat pipes. In the energy conversion device, this waste heat is converted into high-temperature, high-pressure steam, which in turn drives the steam turbine in the power generation device, driving the generator to generate electricity.

[0004] The heat collection tubes in waste heat power generation systems maintain high temperatures for long periods of time due to the heat from the collection box. This can easily affect the temperature of surrounding components, shortening their service life. Therefore, a new technical solution is needed to address this problem. Utility Model Content
