Abstract: In a heat transporting apparatus, a cylinder is filled with a refrigerant and pistons are arranged in the cylinder, which compress and expand the refrigerant in the cylinder. A magnet unit is movably provided around the cylinder to apply a magnetic field to the cylinder, which is alternately increased and decreased in accordance with a movement of the magnet unit. A thermal accumulator is received in the cylinder, which produces heat depending on one of the increasing and decreasing of the magnetic field at the compression of the refrigerant, and absorbs heat depending on the other of the increasing and decreasing of the magnetic field at the expansion of the refrigerant. Heat exchangers are located in the cylinder, which radiates the heat from the refrigerant and thermal accumulator to an exterior of the apparatus, and absorbs external heat and transfers the heat to the refrigerant and thermal accumulator.

Abstract: One surface of a base section having an open portion forming an inlet port of a fluid is thermally connected to a target module to be cooled. Pluralities of fins arranged in parallel are mounted on the other surface of a base section in a direction substantially perpendicular to the base section. A fan is arranged to permit the fluid to flow through the clearance between the adjacent fins. A wall section open to the inlet port of the fluid is mounted on the base section. A part of the wall section constitutes a detachable lid section. A partition plate having through-holes formed therein is arranged between the base section and the lid section so as to divide the space between the base section and the lid section into two fluid flowing channels consisting of a main flowing channel and an auxiliary flowing channel.
