An internal air adjustment device that includes a first composition adjustment unit and a second composition adjustment unit. The first composition adjustment unit separates supply air from external air, the supply air having a composition that differs from a composition of the external air, and supplies the supply air into a transport container. The second composition adjustment unit separates discharge air from internal air, the discharge air having a composition that differs from a composition of the internal air, and discharges the discharge air to outside of the transport container. The internal air adjustment device is capable of properly controlling the composition of the internal air in the transport container.

Low Reynolds number forced convection heat transport within the fin channels enhanced by deliberate formation of unsteady, small-scale vortical motions using elastically fluttering thin-film reeds. The vortical motions substantially increase the local heat transfer coefficient at the channel walls and mixing between the wall thermal boundary layers and the cooler core flow. The flow mechanisms associated with production, advection and dissipation of these small-scale motions are investigated in a modular, high aspect ratio channel using micro-PIV, video imaging of the reed motion, and hot-wire anemometry. The global heat transfer enhancement in a modular heat sink prototype shows that the reed-induced small scale motions increase the turbulent kinetic energy of the flow even when the base flow undergoes transition to turbulence, leading to an increase in the local and global Nusselt number that is sustained at higher Re and a minor relative increase in losses.
