Abstract:
1. A phase change material heat exchanger device, comprising: at least first and second heat exchanger cells, each dimensioned for fluid flow therethrough, with fluid flow directions that alternately reverse within each cell while remaining mutually opposite, at least one of said first and second heat exchanger cells comprising a phase change material (PCM) accumulator, means for alternately reversing said fluid flow directions through said first and second heat exchanger cells, so that said fluid flow directions remain mutually opposite, a vortex tube having an inlet port, a first outlet port, and a second outlet port, and a fluid-tight chamber in which the vortex tube is located, wherein the outlet ports of the vortex tube lead to one of the following: said first heat exchanger cell, said second heat exchanger cell or outside said heat exchanger device.
