Description

Technical Field

[0001] The invention relates to the technical field of heat recovery of phase-change heat pipes, and in particular to a heat recovery device of a phase-change heat pipe. Background Art

[0002] Phase change heat pipe is a highly efficient thermal management device that uses the heat absorption and release process of material phase change to transfer heat. It is mainly composed of a sealed metal tube and a phase change material filled inside. When the heat source side of the phase change heat pipe is heated, the phase change material absorbs heat and undergoes a phase change, so that the heat is absorbed and stored. This process keeps the temperature on the heat source side stable or lowers, while the released heat is conducted to the cooling side through the tube wall.

[0003] Heat recovery refers to the process of using heat or thermal energy that would otherwise be wasted, recovering it and reusing it through various technical means. The application of this technology aims to improve energy efficiency, reduce energy consumption, and thus reduce costs and environmental impact. Heat recovery technology plays an important role in modern industry and life, and is one of the key technologies for achieving sustainable development and effective use of resources. With the advancement of technology and the popularization of its application, heat recovery will continue to play an important role in various fields.

[0004] When using traditional phase-change heat pipes, they will use filters to filter the incoming air to ensure that the air quality meets specific requirements or protect the internal components of the phase-change heat pipe from the influence of particulate matter. However, when using filters, traditional phase-change heat pipes are not convenient to automatically process the filters in time, resulting in increased resistance of the air filtration system of the filters, which may affect the air flow and heat transfer efficiency of the surrounding environment. Especially in applications that require efficient heat dissipation or temperature control, this may affect the thermal management performance of the equipment.
