A micro heat pipe is evacuated and filling apparatus and methods

The present invention provides a kind of micro heat pipes was evacuated and filling apparatus and methods, including vacuum systems and filling two-part injection system. Wherein the vacuum system consists of a vacuum pump, the digital vacuum gauge, a pressure sensor and the reservoir tank connected successively composition, each portion connected through a line, the line and opened and closed by a needle valve; filling system includes a burette, micro-injection liquid, transparent silicone hoses, etc., and in different parts of transparent silicone hose disposed a plurality of Robert hose clamp may be similar switching function of the valve. This device configuration simple and economical, only through the operation of a limited step valve can achieve evacuation and filling process, injection of the working fluid amount charged in the micro heat pipes be precisely controlled, and can be micro heat inside of the tube cavity volume accurate measurement.
