Heat Pipes & Vapor Chamber / Integrated Vapor Chamber Heat Sinks BACK
A vapor chamber is a high-end thermal management device that can rapidly spread heat from a small source to a large platform of area. A properly designed vapor chamber with heat sink can improve the thermal performance by 10- 30% over copper, and heat pipe based solutions. A vapor chamber is much lighter than solid copper, due to its internal chamber structure. In many cases, a vapor chamber based heat sink weighs the same as an extruded aluminum heat sink, but works much better than a copper heat sink.
Vapor Chamber Design Guidelines,
-Size : 400x400 mm (maximum)
-Thickness: 3.0 mm (minimum)
-Shape limitation : Base on stamping technology
-Heat Source : ≧ 15x15 mm
-Q-max : ≦ 150W
-Force Loading : ≦60 lb
A vapor chamber consists of a sealed vacuum vessel, with an internal wicking structure, and a small amount of working fluid. Rego’s Vapor Chamber is multi-layered copper mesh wick bonded. Mesh wick structure is similar to sinter powder wick structure but with better pore size uniformity. Compound Multi-layer Mesh Wick performs better than simplex sinter wick structure.
Rego’s vapor chambers are very reliable thermal devices. They are well tested in production line according to the following tests,
-100% Helium leakage test
-Water Quality Inspection, on line detecting.
-100% Weight filling quantity
-100% Thermal aging
-100% Thermal Performance test
