PURPOSE: A cooling type helmet using a thermal semiconductor is provided to continuously supply a worker with the fresh air, thus to enable the worker to effectively spray any agricultural medicines or fertilizer in a safe condition. CONSTITUTION: The cooling type helmet(A) comprises a cool air preservation gel pack(4), a cooling plate(7), a thermal semiconductor(8), a heat release plate(9), a heat release fin(10), an air suction fan motor(6), a hot air discharge fan motor(11), a filter(5), a transparent window(3), and a control device(C) for the thermal semiconductor. The control device consists of a battery(13), a power switch(14), and a speed controller(15) for adjusting the speed of the air suction fan motor. The filter and the air suction fan motor are mounted between an outer body(1) and an inner body(2) of the helmet.
