Abstract
A cooling device is provided with a heat sink having a plurality of fins, and a plasma actuator. Flow paths are formed between adjacent ones of the fins. The plasma actuator is provided away from the fins where the flow paths are formed. The plasma actuator has electrodes that are arranged offset in the flow path direction. The plasma actuator generates an induced air flow flowing in a direction of the flow path in the central region between adjacent fins.
Claims11
A cooling device comprising:
- a heat sink in which a flow path is formed between adjacent fins;
- and
- a plasma actuator,
- the plasma actuator being provided away from the fins where the flow path is formed, having electrodes arranged offset in a flow path direction, and being configured to generate an induced air flow flowing in a central region between the adjacent fins in the flow path direction.
