Abstract
An apparatus for acoustically cooling automotive electronics in which an acoustic driver and acoustic reflector are disposed within a hollow member, such as a cross-car-beam of a vehicle. The frequency of the acoustic driver and the distance between the acoustic driver and the acoustic reflector are selected to generate a standing acoustic wave within the hollow member. The standing acoustic wave will generate a fluid flow providing forced air convection cooling of a base or its extension on which
Claims15
An apparatus for acoustic cooling an external heat load comprising:
- a hollow member;
- a fluid filling said hollow member;
- a heat transport member connected between the external heat load and the hollow member, said heat transport member being in intimate thermal contact with said hollow member;
- an acoustic wave generator operative to generate an acoustic wave in said hollow member at a predetermined frequency;
- and
- an acoustic reflector disposed in said hollow member at a location selected to reflect said acoustic wave to produce a standing acoustic wave at a location adjacent to said heat transport member, said standing acoustic wave inducing a circulating flow of said fluid inside the hollow member transporting, by forced convection, the heat energy transported to said hollow member by the heat transport member to a remote location of hollow member acting as a heat sink.
