Abstract: The PCB wind tunnel test device includes: a flow-stabilizing structure, which includes: a box used to provide flow channels for air entering the flow-stabilizing structure; flow-stabilizing plates, which are inserted into the cavities of the box in a layered manner; a wind source, arranged at an air inlet of the flow-stabilizing structure; a test device, arranged at the outlet of the flow-stabilizing structure. When the flow-stabilizing structure receives the wind energy provided by the wind source, the state of the air flow is adjusted by flow stabilization, so that the test device tests the air passing through the flow-stabilizing structure. The present invention solves the problem that conventional wind tunnels cannot test at low air volumes and enables PCB testing at different ambient temperatures.
