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.

Cooling device

A cooling device cools an electronic component using a plasma actuator provided with a dielectric, a first electrode arranged on one surface of the dielectric to generate an induced flow, and a second electrode arranged on the other surface of the dielectric, in which the electronic component and a third electrode are arranged in a flow direction of the induced flow, and a voltage applied to the third electrode is a voltage that generates a potential difference, which is capable of attracting the induced flow, between the first electrode and the third electrode.

A cooling apparatus including a heat sink to which a heat generating body is joined, a main flow generation device configured to generate a main flow for cooling the heat sink, and an induced flow generation device configured to electrically generate an induced flow. The induced flow generation device is provided to a support member facing the heat sink.
