Interface Plate: Thickness 3-10 mm, Flatness ≤0.05 mm

Component Specifications

Definition

An interface plate is a precision-engineered component used in thermal management systems to create a reliable thermal interface between heat-generating elements (e.g., processors, power modules) and cooling devices (e.g., heat sinks, cold plates). It ensures efficient heat dissipation by minimizing thermal resistance through proper surface contact and material conductivity.

Working Principle

Operates on thermal conduction principles, transferring heat from a source to a sink via direct contact. The plate's flatness and material properties optimize thermal impedance, while mounting pressure ensures minimal air gaps for maximum heat transfer efficiency.

Materials

Typically aluminum 6061-T6 or copper C11000 for balance of conductivity and cost; may include thermal interface materials (TIMs) like graphite pads or phase-change compounds on surfaces.
