The invention discloses a refrigerating helmet. The refrigerating helmet comprises a helmet body, wherein a liquid refrigerating module and an air refrigerating module, wherein the liquid refrigerating module and the air refrigerating module are connected with a control module and a power supply module, the liquid refrigerating module is communicated with liquid refrigerating pipes respectively mounted on a surrounding neck of the helmet body and in the helmet body, a low-temperature liquid is guided to flow out of a liquid refrigerator by virtue of natural circulation, enters the liquid refrigerating pipes to circularly flow and absorbs heat generated by the neck of a human body and reenters the liquid refrigerator by virtue of natural circulation after temperature rise, thereby cooling the neck and the head of a wearer; and the air refrigerating module is mounted in front of the helmet body, air is introduced to an air cooler by virtue of a mini-sized fan, and cold air blows to the face of the wearer after being returned by a wind board in front of the helmet body, thereby realizing the cooling or perspiration of the face.
