Abstract:
1. A cooling method for a heated body, comprising: providing a double-acting device, said double-acting device comprising a chamber divided into at least two sub-chambers by a separating element; providing an input system connected to said chamber for passing a fluid into said chamber; providing an output system including a passive asymmetric element and at least two sets of passages respectively connected to said at least two sub-chambers for outputting the fluid to the heated body; controlling said separating element of said double-acting device to act reciprocatingly for antiphasely passing said fluid out of each of said at least two sub-chambers so that two oscillating jets and a train of vortices of said fluids are generated by the antiphase passing of said fluid; and allowing said fluid to flow through the passive asymmetric element for enhancing said train of vortices, wherein an enhancement of heat exchange of said heated body is induced by said two oscillating jets directing to a surface of said heated body and said train of vortices driving a surrounding fluid with a relatively low temperature rolling thereinto.
