[0045] A high-power laser heat management device based on spray vaporization of the present invention, a laser heat sink 8 is provided on the high-power laser, and the microstructure of the heat dissipation surface of the laser heat sink 8 is a groove structure, which can enhance the heat exchange effect. Such as figure 1 As shown, the heat management device includes a high-pressure spray chamber 9 installed on the laser heat sink 8, and the high-pressure spray chamber 9 is provided with a refrigerant for converting liquid refrigerant into mist liquid droplets and spraying it on the laser heat sink 8. The spray nozzle array 7 and an air pressure sensor 13 on the upper surface, the mist-like liquid droplet refrigerant sprayed on the laser heat sink 8 is partially vaporized to form a gas refrigerant, which can increase the pressure in the high-pressure spray chamber 9, and the air pressure sensor 13 can measure in real time The pressure in the high-pressure spray chamber 9 is fe...
