HEAT PIPE Russian patent published in 2010 - IPC F28D15/02 E02D3/115 

FIELD: heating systems.

SUBSTANCE: invention is intended for cooling of ground and can be used in construction industry. Heat pipe includes tubular housing, condenser of which is located above the ground surface, and evaporator - in cooled ground, which are provided with external finnings, filler pipe for vacuum treatment and filling of heat pipe with heat carrier with its further sealing. Heat pipe is provided with removable refill capacity tightly installed on the end of heat pipe condenser by means of coupling nut and by using annular seal. Filler pipe is connected to cavity of the above capacity, through end wall of which in direction of longitudinal axis of heat pipe there tightly installed is female wrench for the sealing screw installed in the edge of condenser along longitudinal line of heat pipe. From lower edge of sealing screw there made is central channel with side outlet for passage of heat carrier from cavity of removable refill capacity to cavity of heat pipe. Side outlet is located above annular seal of sealing screw when it is not completely screwed and below the above annular seal when the screw is completely tightened. Heat pipe is provided with sealing element in the form of a plug for installation instead of removable refill capacity after filling is completed.
