High heat density alloy plate synthesis technology: the traditional sunflower radiator with pure aluminum plate, because the heat flux of aluminum is small, the impact of thermal conductivity and pure aluminum tapping teeth can not be locked, ① lead to the light source substrate can not be tight with the radiator in a long time. With the heat dissipation body from the light source substrate, loss of heat dissipation; ② optical lens ring can not be long-term effective compression which lead to not water-proof; ③ can not achieve hot-melt welding. High heat density alloy plate can solve the above defects, in the structural cooling technology is a technological breakthrough.

Instant high temperature hot melt welding technology: learn from Germany's aluminum welding technology, after repeated numerous experiments, the use of metal relative to high-speed movement to produce heat, instantaneous melting metal contact surface, and then the appropriate time parameters to complete the emergency stop welding. So that the manufacture of heat-conductive cavities without molecular-grade leakage can be achieved. The technology is the company's original technology, the traditional process can not be completed.

Low boiling point heat transfer medium synthesis technology: On the basis of the experiment, a low boiling point heat medium is synthesized, which has a boiling point of 16 ° C in the vacuum state and no corrosion in the heat conduction cavity, which greatly improves the heat transfer of the phase change medium Speed, to achieve a moment of thermal conductivity, reducing the temperature rise. Than the traditional radiator to reduce the temperature rise around 30°C.

High vacuum forming technology: the heat inside the cavity vacuum will greatly affect the phase change heat transfer medium heat transfer effect, the use of traditional vacuum is difficult to achieve a high degree of vacuum, after a long period of time to master the high vacuum forming technology, Up to 10-2.

Reasonable thermal design technology: the use of supercomputing system for thermal simulation, thermal conductivity, heat height match, to save material, reduce costs, reduce the weight of the purpose.
