摘要： The present invention is directed to a cooling system (1) for electronic components (4). The cooling system (1) comprises means (7) for producing cyclic air pressure fluctuations, wherein the electronic components (4) are distanced from the pressure producing means (7). In the vicinity of the electronic components (4) are situated means (5), preferably restrictions like holes, which are affected by the cyclic air pressure fluctuations, and which produce cyclic air jets (6). The air jets (6) affect the surface of the electronic component (4), and since the air jets (6) originate directly in the vicinity of the electronic components (4), an efficient heat transfer is affected. Preferably, the pressure producing means (7) actuate a pressure Pc inside a chamber (2), and turbulent air jets (6) are produced through holes (5) of a substrate (3), onto which electronic components (4) are mounted.

摘要： A system and method for loading gases or other soluble fuel or catalyst materials into a liquid cavitation medium such as a liquid metal, which may be cavitated under static pressure so as to cause a desired energetic reaction in the dissolved gaseous fuel substance at the cavitation sites. Examples of liquid cavitation media can include liquid metals such as liquid gallium, and examples of dissolved gaseous fuel substances can include deuterium. Sufficiently intense cavitation (for example carried out under high static pressures) may provide energetic reactions in the fuel that release subatomic particles therefrom such as neutrons. The present system and method may be used to load such gaseous fuels into other liquid metal systems, including systems that are non-cavitation-based or that cause cavitation in the liquid by means other than the acoustical drivers described in the preferred embodiments.
