PASSIVE COOLING HEAT EXCHANGE SYSTEM USING CAPSULE-TYPE PHASE CHANGE MATERIAL

摘要

The present invention relates to a piping system including an inlet portion communicating with the inside of a cooling object and a discharge portion communicating with the outside and containing a fluid and a capsule inside / outside; An internal heat exchanger connected to a pipe provided inside the cooling object; And an external heat exchanger connected to the piping provided outside the object to be cooled, wherein a phase change material (PCM) is stored in the capsule, and the phase change is converted into a liquid state or a solid state, The heat inside the cooling object is discharged to the outside while being circulated to the inside and the outside of the cooling object due to the difference in density in the pipe.
