A flat plate micro heat pipe phase change heat storage and release system

Abstract

The invention discloses a flat-plate micro heat pipe phase-change heat storage and release system. The flat-plate micro heat pipe phase-change heat storage and release system is characterized by comprising a flat-plate micro heat pipe heat storage device, a first four-way valve, a heat exchanger, a second four-way valve and a pipeline, wherein a heat exchange flat plate is arranged in the heat storage device; a plurality of micro heat pipes are arranged in the heat exchange flat plate; heat exchange working media are contained in the heat pipes; the upper end of the heat exchange flat plate is a heat-extracting end, and the lower end of the heat exchange flat plate is a heating end; the heat-extracting end is attached to a heat release pipe; the heating end is attached to a heat charging pipe; at least the heat exchange flat plate is wrapped by a heat storage box; and inner gaps of the heat storage box are filled with heat storage materials. When a heat source (waste heat of factories, solar energy and the like) generates redundant heat which is not completely consumed by a user, a heat storage stage of the system is started, the heat source transfers heat to the heat exchanger through a heat source heat charging loop, then the heat exchanger supplies the heat to the heat storage device through a system heat release loop, and therefore the heat can be stored; and when an external heat source cannot meet the requirement of the user, a heat release stage of the system is started, finally the user side temperature is raised, and the heating requirement is met.
