Description

technical field [0001] The invention relates to the technical field of design and manufacture of heat pipes, in particular to a cold-state filling system and method for high-temperature alkali metal heat pipes. Background technique [0002] The high-temperature alkali metal heat pipe is an advanced passive heat exchange device based on the phase conversion heat of liquid alkali metal, which has the characteristics of high isothermality, high heat transfer efficiency and high reliability. High-temperature alkali metal heat pipes have broad application prospects in space nuclear reactors because of their excellent heat transfer characteristics, good safety, reliability, and passive heat transfer characteristics. The filling technology of high temperature alkali metal heat pipe is a crucial part in the manufacturing process of high temperature alkali metal heat pipe. Alkali metal purity (>99%), vacuum degree (10 -4 <), filling volume and filling technology have a signif...
