The utility model relates to a negative pressure air flow cooling device. The device comprises an exhaust fan and a remote controller, wherein a signal receiver is arranged on the exhaust fan, a numerical control chip is arranged in the exhaust fan, the signal receiver is connected with the numerical control chip, a motor, a shutter and a plurality of fan blades are arranged on the exhaust fan, the motor is connected with the fan blades, the motor and the shutter are respectively connected with the numerical control chip, the exhaust fan is connected with a wind direction sensor, and the winddirection sensor is connected with the numerical control chip in the exhaust fan. Indoor and outdoor air convection is accelerated by utilizing negative pressure generated in space, so that indoor andoutdoor temperature exchange is accelerated, the use cost is low, the effect is good, and the indoor temperature can be reduced by 2-8 DEG C in different areas; the wind direction sensor can preventnatural convection of air f
