Phase Change Vapor Chamber
Our Technologies – Vacuum vapor Chamber
A vapor chamber is a planar heat pipe that can spread heat in two dimensions. The benefits of vapor chambers include that they are isothermal and can be used to cool multiple components while sustaining low thermal resistance.
Two-dimensional heat transfer performance is superior to that of metal materials and heat pipes.
Thermal conductivity equivalent to 5000W/m·K or more.
Meet the heat dissipation requirements of power devices within 10W-10KW and above.
01
Super Thermal Conductivity
Vapor chamber heat sinks utilize a two-phase heat transfer mechanism that provides exceptionally high thermal conductivity, far surpassing traditional solid metal heat sinks.
02
Without Power Consumption
Vapor chambers operate passively, requiring no external power source. It relies on the natural phase change cycle of the working fluid with no pumps, fans, or moving parts required for operation
03
Light Weight and Small Size
The thin profile allows for use in space-constrained applications and reduces the overall weight of cooling solutions in portable devices
04
Cost Effective for Heat Dissipation
While initial costs may be higher than simple heat sinks, vapor chambers can be cost-effective in the long run because it reduces the need for additional cooling components like fans or liquid cooling systems

Alternative Technologies in vapor chamber Heatsink
High heat density alloy plate synthesis technology
The traditional sunflower heatsink 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. Then the traditional radiator to reduce the temperature rise around 30°C.
High vacuum forming technology
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
Reasonable thermal design technology
The use of supercomputing system for thermal simulation, thermal conductivity, heat height match, to save material, reduce costs, reducing the weight of the purpose.
