The mixing pipeline 4 is a place where the cooling liquid is vaporized, and the safety helmet is distributed on the mixing pipeline 4, so that the heat of the safety helmet is uniformly absorbed, and the heat absorption effect is good.

The main function of safety helmet is the protection head, and connecting support 5 connects the cap body 1 and heat-conducting plate 7, has left the space for hybrid tube 4 to because there is the clearance between the connecting support 5, be not inseparable entity, provide certain buffering for the bearing impact of safety helmet again, improved the security of safety helmet. The heat conducting plate 7 is made of a material with good heat conductivity, and is made of an alloy material with good buffering performance in consideration of the protection characteristic of the safety helmet. The heat exchange module 6 is located at the ear-covering part 101 of the cap body 1 and comprises a heat exchange block 602 and a structure for accommodating the heat exchange block 602. In this embodiment, the heat exchange block 602 is placed in a drawer type structure, and the heat exchange block 602 can be conveniently replaced by arranging the horizontal pull drawer 601.

Heat exchange block 602 refers to a solid or liquid having a high specific heat capacity, which can absorb a large amount of heat and has a less large temperature variation. For directly using heat transfer piece 602 to come the safety helmet cooling, the radiating mode of coolant liquid vaporization is directed at heat-conducting plate 7, and heat-conducting plate 7 is inside the safety helmet, takes place heat exchange with external world fewly for the radiating mode of coolant liquid vaporization concentrates the radiating effect inside the safety helmet better more, and directly use heat transfer piece 602 can lead to on external heat exchange to heat transfer piece 602, leads to the efficiency of heat transfer piece 602 to be extravagant, has shortened the live time simultaneously greatly. The casing is made of a heat insulating material, which has a heat insulating effect to prevent external heat from being exchanged to the heat exchange block 602. And the heat radiation effect of directly using heat exchange block 602 is uncontrollable, the safety helmet contacts with the head, and the temperature is too low to lead to the safety helmet being unable to wear. The wind power driving module 2 and the cooling circulation module 3 are both connected with a controller, the controller can control the air supply rate of the fan 201, the supply amount of the cooling liquid and the supply speed of the cooling liquid, the temperature inside the safety helmet is adjusted to be suitable in real time, and the comfort is improved.
