Sensor cooling device

The invention provides a sensor cooling device, which comprises a box body and an upper cover plate, the upper cover plate is fixed on the box body, one side of the box body is provided with a measurement window, the inner side of the measurement window is provided with heat insulation glass, the measurement window and the heat insulation glass are spaced, and the measurement window is located in the range of the heat insulation glass on orthographic projection. Diversion trenches are distributed around the measuring window in the box body, an air inlet is formed in one side, opposite to the measuring window, of the box body, and a first stringer is arranged at the bottom of the box body; second stringers are distributed on the inner side of the upper cover plate, and the second stringers are distributed around the air inlet in a fan shape. The cooling device is simple in structure, uniform cooling of the sensor is achieved, the cooling efficiency is high, and it is guaranteed that the sensor normally works a
