Problems solved by technology

[0003] Generally, the working fluid working in the 100-200K temperature range has a relatively low saturated vapor pressure at room temperature. In this case, if it is filled at room temperature, the amount of working fluid gas often cannot meet the design requirements.
The use of low-temperature filling requires constant control of the quality of the filling process, and repeated filling often leads to relatively large errors.

Description

Technical field [0001] The present invention relates to the field of working fluid filling, in particular, to a working fluid filling system and a method of working fluid filling. Background [0002] There are two common methods for filling the working fluid of the loop heat pipe: normal temperature filling and low temperature filling. Normal temperature filling is suitable for normal temperature loop heat pipes and low temperature loop heat pipes with high working fluid saturation pressure at room temperature. The low temperature filling is mainly used for low temperature loop heat pipe, it is by cooling the working medium gas that has entered the tube body, while refilling the new working medium gas, until the filling of the working mass to meet the pre-calculated requirements, low temperature filling often needs to repeatedly fill the heat pipe into the working fluid. [0003] Generally working in the 100-200K temperature zone of the working medium, its saturated vapor pressur...
