Vapour Chambers

Ultra-High Thermal Conductivity: Vapor chamber technology achieves exceptional two-dimensional heat spreading with thermal conductivity exceeding 5000 W/m·K-a performance far beyond that of conventional metal or heat-pipe solutions.

Passive Phase-Change Operation: Utilizes an internal working fluid’s evaporation-condensation cycle to transfer heat reliably without requiring external power, pumps, or moving parts.

Thin, Lightweight, High-Efficiency Design: Compact, flat configuration enables efficient cooling in space-constrained or lightweight applications, especially when paired with LED lighting systems.

Robust Manufacturing Integrity: Boreless construction via instantaneous hot-melt welding ensures molecular-level sealing to prevent leakage and ensure long-term durability and performance.

Wide Heat Load Compatibility: Designed to handle heat dissipation ranging from 10 W up to 10 kW and beyond, making it suitable for a wide variety of high-power applications.

Precision Thermal Performance: Offers excellent temperature uniformity-temperature difference from bottom to top plate under rated flux remains ≤ 7 °C; thermal resistance ≤ 0.14 °C/W.

Proven Reliability Standards: Operates in ambient temperatures from -50 °C to 120 °C; withstands vibration (0-200 Hz) and maintains seal integrity (< 2x10?? Pa·L/s helium leak rate).

Vapour Chambers-FAQ's

What makes vapor chamber heat sinks superior to regular heat sinks?

They offer vastly higher thermal conductivity-over 5000 W/m·K-through efficient two-dimensional heat spreading via phase-change cycles.

Do they require external power or moving parts?

No-vapor chambers are fully passive and rely on natural evaporation and condensation within sealed cavities.

What are typical thermal performance indicators?

Temperature variation across the plate is ≤ 7 °C under rated load, with thermal resistance no greater than 0.14 °C/W.

What temperature conditions can they withstand?

They function reliably in environments ranging from -50 °C to 120 °C, and endure vibration up to 200 Hz.

Is leakage a concern?

No-the unit’s hot-melt welding process achieves helium leak rates below 2x10?? Pa·L/s, ensuring long-term seal stability.

How adaptable are they in size and design?

Fully customizable in footprint, thickness, and surface treatment to match lighting components or electronics platforms.

What makes the construction robust?

The use of specialized low-boiling-point working fluid and vacuum-formed internal structure ensures high reliability and thermal efficiency.

Do you support custom branding or packaging?

Yes-we offer ODM/OEM services including branding, tailored packaging, and integrated thermal engineering support.
