An air turbulent motion simulation micro device is characterized in that: the bottom of a straight cylinder B is connected with a cone, the lateral lower wall of the cone is connected with a support by a convex edge, the upper part of the straight cylinder B is connected with a straight cylinder A, the lateral upper wall of the straight cylinder B is connected with an air inlet curve along a circumferential tangential direction, one end of an air inlet tube is connected with the air inlet curve, the other end is connected with an outlet of a blower fan through a hose, a power supply end of the blower fan is connected with a blower fan controller, and an air outlet of the blower fan is connected with the air inlet tube by a hose. The air inlet tube is connected with the straight cylinder B by a support stiffened plate, and a heater or a refrigerator is arranged in the air inlet tube and connected with a temperature controller outside the air inlet tube by cables. A power supply is connected with the blower fan controller and the temperature controller. The air flow is realized by adjusting blower fan power through the blower fan controller, and the air temperature is realized by adjusting the power of the heater or the refrigerator through the temperature controller. The air turbulent motion simulation micro device has the advantages of simple structure, adjustable parameters and microminiature.
