Description

technical field [0001] The invention relates to the technical field of pulsating heat pipes, in particular to a pulsating heat pipe with a variable heat insulation section. Background technique [0002] Energy management is a topic of general concern in the field of global energy and environment. In terms of thermal management, the development of environmentally friendly heat transfer systems with low energy consumption is one of the important research directions in the field of thermal management. As a new type of heat transfer device, the pulsating heat pipe has higher heat transfer efficiency, higher resistance to dry burning, and strong environmental adaptability than traditional heat pipes. At the same time, it has the characteristics of simple structure, small volume and low cost. The structure of the pulsating heat pipe is mainly composed of three parts: evaporation section, condensation section and adiabatic section. In actual use, the evaporating section is usual...
