Product Introduction

Our philosophy is to serve our customers, not only to provide the high quality Anodized Heatsink, Vapor Chamber Heat Sink, Cooling Plate Heat Sinks they need, but also the attentive service they require. We adhere to people-oriented, employee interests first, investor interests second, that talent is the company's most valuable property. We believe that companies should think about the impact of their activities on society from a long-term perspective. We aim at product diversification, price rationalization and internationalization of sales.

Vapor chambers (VC heat sink) offer superior thermal spreading performance over traditional solid metal heat spreaders by taking advantage of two-phase liquid/vapor transport. Their lower weight and height over traditional solutions couples with their high thermal conductivity to give extremely low thermal resistance in-plane as well as through the thickness of the vapor chamber. Vapor Chambers (VC heat sink) are best suited for components with high heat densities (larger TDP in small chip sizes) which need to spread their heat to a larger area heat exchanger to achieve safe operating temperatures, thereby providing extended life and reliability for components and applied products.

Vapor chamber features

Ø Heat spreading effect of vapor chamber is better than copper block when transferring high heat load through small distance path.

Ø Sintering Cu powder can have flexibility in different heat sink design. Wick structure have to be optimized for the different heat flux input and multi heat sources.

Ø Diffusion Bonding can get vapor chamber more reliable due to better joint.

Ø The process of tube type vapor chamber, thin vapor chamber and traditional vapor chamber can be integrated.
