（Core Technologies）
1. Dual-mode cooling system: Supports "pre-cooling mode" (quickly cool down to the target temperature before treatment) and "real-time cooling mode" (continuous temperature control during treatment). The cooling head has a contact area of 50cm², suitable for different treatment parts; 2. Precise temperature control technology: Adopts semiconductor refrigeration + phase change energy storage technology, with a temperature control accuracy of ±0.5℃. The touch screen can preset 3 groups of commonly used temperature parameters to meet the needs of different laser equipment; 3. High-efficiency heat transfer material: The cooling head is made of medical-grade sapphire, whose thermal conductivity is 30% higher than that of metal, with good biocompatibility to avoid skin irritation; 4. Intelligent adaptation design: Built-in equipment identification module, which can automatically match the model of the connected laser equipment and adjust the cooling intensity synchronously without manual setting; 5. Safety protection system: Equipped with a skin temperature sensor, which automatically shuts down when the temperature is lower than -6℃ or higher than 12℃. It also has an anti-condensation design to protect the equipment and skin.
（Working Principle）
Based on the "dual mechanism of heat conduction and heat insulation", it reduces skin thermal damage through active cooling, and the core principle is divided into three stages:
• Pre-cooling stage: 1-3 minutes before treatment, the cooling head contacts the skin, and the semiconductor refrigeration module cools the skin epidermis to 4-8℃ through sapphire, reducing the skin heat capacity and reserving a "thermal buffer space" for the subsequent laser energy action;
• Real-time cooling stage: During laser treatment, the cooling head fits the skin synchronously, and the phase change energy storage material absorbs the instantaneous thermal energy generated by the laser, stably controlling the epidermis temperature within a safe range (≥0℃ to avoid frostbite), while reducing the conduction of thermal energy to the dermis;
• Temperature control feedback stage: The skin temperature sensor collects temperature data in real time and transmits it to the host control system. When the temperature deviates from the preset value, the system immediately adjusts the refrigeration power to ensure stable cooling effect and avoid overcooling or insufficient cooling.
