Cooling device with air shower

摘要

A cooling device (10) with an air shower (20) is disclosed. The cooling device (10) includes a heat mass (11) with a plurality of spaced apart fins (17) connected therewith. An air shower (20) including an injector face (23) with a plurality of disrupter orifices (25) is positioned over the fins (17) so that the disrupter orifices (25) direct a second air flow (A2) into slots (S) between adjacent fins (17). A first air flow (A1) flowing through the slots (S) is impinged upon and is disrupted by the second air flow (A2) resulting in the generation of turbulence (D) in the first air flow (A1) . Consequently, a thermal boundary layer in the first air flow (A1) is disrupted and a rate of heat transfer from the fins (17) and the heat mass (11) are increased.
