With the term “thermal management” we refer to all the technologies that can be applied to modify the temperature of a specific system, using specific mechanisms such as conduction, convection and radiation.
Heat transfer mechanisms
Heat transfer consists in the transfer of thermal energy between two thermodynamic systems with different temperature.. There are three heat transfer mechanisms: conduction, convection and radiation.
Heat transfer by conduction
Conduction is enabled when there is a transfer of thermal energy between two objects that are in in direct contact , with the hottest object tranferring energy to the coldest one. Conduction can be considered the most efficient mechanism of heat transfer, as it requires the least amount of exchange surface to transfer the largest amount of thermal energy.
Heat transfer by convection
The convection mechanism, which is typical of fluids, concerns heat transfer by means of macroscopic motion of molecules, forming currents of flowing gas or fluids.
Heat transfer by radiation
Heat transfer by radiation takes place through the emission of energy in the form of photons or electromagnetic waves: unlike heat transfer by conduction or convection, radiation does not require a medium for heat transfer.
Thermal management in BeDimensional’s solutions
Thermal management is a topic of great interest for the modern industry that is always looking for innovative solutions to enhance product performance and characteristics. Thanks to their intrinsic properties, Graphene and Hexagonal Boron Nitride incorporated within a polymer matrix (liquid or solid) are able to transfer their thermal conductivity to semi-finite or finite products, transforming them from thermal insulators into thermal conductors.
Bedimensional’s solutions and products as B-LEAF coating 10001 and G-LEAF coating 00001 enable the transfer of the thermal properties of few-layers Graphene and h-BN to products such as paints and plastics.
