Title:
AIRFLOW CONTROL METHOD OF HEAT SINK
Document Type and Number:
Japanese Patent JP2023158719
Kind Code:
A
Abstract:
To solve a problem of high power consumption in conventional cooling devices using plasma actuators.SOLUTION: In a heat sink H in which a plurality of fins 2 are arranged, a method for controlling an airflow in a flow path 3 formed between the fins 2, includes: arranging one plasma actuator P1 and the other plasma actuator P2, respectively for one fin 2 and the other fin 2 forming the flow path 3, in a direction that generates an induced air flow F2 in a direction along a main flow F1 in the flow path 3; intermittently generating the induced air flow F2 by burst driving each of the one plasma actuator P1 and the other plasma actuator P2; and intermittently generating a vortex flow V due to interference between the main flow F1 and the induced air flow F2 in the flow path 3. Accordingly, cooling efficiency is improved and power consumption is reduced in the heat sink H using the plasma actuator P.SELECTED DRAWING: Figure 1
