Abstract:
1. A heat transport apparatus comprising: a heat source having a generally planar plate surface; a heat transport member defining therein a continuously provided heat-transport passage in which a fluid is sealed, the heat transport member having a heat exchange portion configured to absorb heat from the heat source; and an oscillating member configured to oscillate the fluid in the heat-transport passage, wherein: the heat exchange portion has a contact surface that contacts the planar plate surface of the heat source the heat transport member has approximately an L shape in cross-section, which includes a perpendicular portion extending from the contact surface to be generally perpendicular to the planar plate surface, a parallel portion extending generally parallel with the planar plate surface, and a bent portion bent from the perpendicular portion to the parallel portion; and the heat-transport passage is U-turned at the heat exchange portion to have adjacent passage portions directly communicating with the heat exchange portion, and the adjacent passage portions are configured in contact with each other to perform a heat exchange therebetween; the heat transfer member includes a plurality of the heat transport members having L-shapes in cross section that have different dimensions in the perpendicular portions and the parallel portions and are stacked with each other in the L-shapes to define plural heat-transport passages, the heat exchange portion of each of the heat transport members is configured to contact the planar plate surface at the contact surface; and the passage portions of adjacent heat-transport passages are in contact with each other.
