G2 Defense Technology Co., Ltd. is a Zhengzhou-based thermal management company specializing in the design and manufacture of high-performance vapor chambers and heat exchangers. We deliver ODM thermal solutions for defense, aerospace and industrial customers who require reliable heat dissipation under extreme conditions.
Our engineering team has deep experience in two-phase heat transfer, CFD simulation and modal analysis. This allows us to co-develop products synchronously with host factories — from concept design and thermal modeling to prototype validation and mass production. Our vapor chambers are engineered to handle heat flux densities of 200+ W/cm², making them suitable for high-density thermal dissipation scenarios such as radar modules, power electronics and laser systems.
The company operates four dedicated design rooms within its Technology Research and Development Department, responsible for heat exchange, filtration, hydraulic pressure and new energy materials research. Supported by complete mechanical equipment and a professional testing laboratory, we can validate thermal performance, structural reliability and fatigue life before delivery.
