Processing and customizing special-shaped temperature balancing plates1

Processing of customized special-shaped vapor chambers

Our company can process and customize various vapor chambers:

Capillary liquid absorbent core structure: sintered copper powder, sintered copper wire mesh;

Welding process: copper paste welding, diffusion welding;

Maximum size: 500*320mm;

Maximum power: 1500W;

Able to design and manufacture copper/water room temperature vapor chambers and copper/methanol low temperature vapor chambers
