A cooling device includes a cooler disposed inside a shell main body formed in a cylindrical shape, and having a first surface facing an inlet nozzle and an outlet nozzle, and a partition member fixed to the first surface, and partitioning a portion between the cooler and an inner peripheral surface of the shell main body into a first space communicating with the inlet nozzle and a second space communicating with the outlet nozzle. The partition member includes a main partition plate disposed between the inlet nozzle and the outlet nozzle in an axial direction, a first guide portion extending from an end portion of the main partition plate toward a first end surface of the shell main body, and a second guide portion extending from an end portion of the main partition plate toward a second end surface of the shell main body.

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.

A heat exchanger includes: a first layer including first flow channels that are microchannels and arranged to extend side by side; and a second layer that is laminated on the first layer and that includes second flow channels that are microchannels and arranged to extend side by side. A first one end-side collective flow channel is in fluid communication with first ends of the first flow channels. A first other end-side collective flow channel is in fluid communication with second ends of the first flow channels. A second one end-side collective flow channel is in fluid communication with first ends of the second flow channels. A second other end-side collective flow channel is in fluid communication with second ends of the second flow channels.

The present disclosure discloses an air conditioner based on a molecular sieve, including a first molecular sieve device, a second molecular sieve device, a reversing valve, and a balancing valve, a refrigerant includes at least one of R600A, R417A, R410C, or R407C, and a depressurization gas includes at least one of hydrogen or helium. An air flow alternately passes through the first molecular sieve device and the second molecular sieve device through the reversing valve, and then flows back through the balancing valve, so that the first molecular sieve device and the second molecular sieve device are regenerated. The first molecular sieve device and the second molecular sieve device are capable of separating a refrigerant from a depressurization gas, and the refrigerant is condensed after reaching a certain concentration to become a liquid refrigerant, and then enters an evaporator again for refrigeration.
