Effective Thermal Conductivity
Effective thermal conductivity describes the overall heat transfer capability of multilayer systems consisting of different materials. In industrial heat plates and thermal platforms, this parameter determines how efficiently heat spreads through the layered structure.
In multilayer architectures the resulting conductivity is determined by the series thermal resistance of individual layers. The interaction between material conductivity, layer thickness and thermal diffusion defines the effective heat transfer behaviour of the entire system.
Architectures such as RevoCORE®, RevoDUR® and RevoTHERM® apply defined multilayer structures in order to control heat flow, temperature homogenization and thermal system stability.
Serial Thermal Resistance Model
The total thermal resistance of a multilayer system is defined by the sum of individual layer resistances. Each layer contributes a specific thermal resistance depending on its thermal conductivity and thickness.
This model allows engineers to calculate the effective thermal conductivity of multilayer heat plates and thermal platforms used in industrial heating applications. By adjusting material combinations and layer geometry, heat flow and temperature distribution can be precisely controlled.
As a result, multilayer architectures provide predictable thermal behaviour and improved heat spreading compared to conventional monolithic metal plates.
Thermal Architecture and Conductivity Distribution
Industrial heat plates can be categorized according to their thermal architecture. The architecture defines how conductive materials are arranged within the structural stack and therefore how efficiently heat spreads across the plate surface.
Class 0 describes monolithic aluminum plates with uniform conductivity across the structure.
Class I describes monolithic stainless steel plates which provide structural stability but relatively low thermal conductivity.
Class II describes bimetal architectures such as RevoTHERM®, consisting of Active Skin and Passive Skin.
Class III introduces trimetal architectures such as RevoCORE®, where a conductive Thermal Spine controls lateral heat distribution between Active Skin and Passive Skin.
Class IV describes high conductivity architectures such as RevoDUR®, where the Thermal Spine is copper based to maximize thermal spreading.
Class V represents custom architectures such as RevoLAB®, where multilayer stacks are engineered for specific thermal systems.
