The LAB-725 from Thermotive is a foil-type thermal strap engineered to provide high-conductance heat transfer for laboratory instruments, cryogenic assemblies, and precision thermal management systems. Designed with a foil width of 0.725 inches (18.4 mm), this strap typically incorporates approximately 200 ultra-thin foils, each with a thickness of 0.001 inches, enabling efficient heat transfer while maintaining flexibility to accommodate mechanical misalignment and vibration in sensitive equipment. This thermal strap utilizes stacked aluminum or copper foils to achieve excellent thermal performance.
It delivers an estimated thermal conductance of approximately 17/x W/K when constructed with aluminum foils and around 31/x W/K when copper foils are used, where x represents the heat-path length in millimeters. The layered foil structure ensures efficient heat spreading while minimizing thermal resistance across connected components. The strap can be customized in multiple geometries, including L, S, U and other modified configurations, allowing it to route thermal pathways effectively through compact or complex mechanical layouts.
The flexible design also helps reduce stress on mounting interfaces while maintaining reliable thermal coupling. Compact, adaptable, and highly conductive, the LAB-725 foil-type thermal strap is ideal for applications requiring precise thermal control, including laboratory instrumentation, cryogenic systems, precision electronics cooling, and other environments where reliable heat transfer and mechanical compliance are essential.
