Product Feature

Features densely spaced fins with narrow fin gaps, and offers flexible customization in height and width to suit various spatial constraints. Compact in size and lightweight, it is an ideal cooling solution for high-power components.

Processing

Bonded fin heat sinks are typically chosen for small-batch production or large single-unit heat sinks. The selection of materials and manufacturing processes significantly impacts heat sink performance, affecting device lifespan and overall system reliability.

Material & Manufacturing Quality:The thermal conductivity of bonded fin heat sinks is heavily influenced by material purity, thickness, and alloy type (e.g., 1060 aluminum, known for strong corrosion resistance and excellent heat dissipation). Poor material quality or defective processes (e.g., casting cracks, shrinkage voids from machining) will degrade heat transfer efficiency.

Surface Finish & Flatness:The surface roughness and flatness of the contact interface directly affect thermal contact resistance and pressure drop.

Assembly Integrity:The riveted joints between the base plate and fins must be secure and smooth to prevent fin loosening or dust accumulation, which could impair functionality or cooling performance.
