These technological difficulties for phase transformation heat pipe, the patent documentation that publication number is CN103075904A proposes temperature when adopting raising phase-change material to fill to ensure that it is for liquid condition, that improves phase-change material fills speed, it is possible to more accurately control the filling weight of phase-change material.But the contaminant problem of residual is not yet solved in heat pipe, working medium flows in filling process and need to ensure flow differential pressure by the pressure by improving working medium source.
For the problem not yet obtaining in heat pipe phase-change working substance filling process solving, this utility model devises and a kind of there will be solid-state under the ambient temperature of-10 DEG C to 45 DEG C, the charging device of the working medium that more than uniform temperature just can melt need to be heated to, the speed that heat pipe fills can be effectively improved, ensure the reliability of heat pipe filling weight and heat pipe, reduce heat pipe and fill the cost of manufacture.
