Heat management is a critical challenge for the reliability of your systems. Are you looking to validate your cooling choices before prototyping? Saïna applies its expertise in thermal simulation to predict the temperatures of your equipment. In this way, we safeguard your designs against the risk of overheating.



The thermal phenomena involved
Conduction
Conduction is a diffusion phenomenon that allows heat to spread within a solid, liquid or gas. It is specific to each material and is expressed by thermal conductivity.
Temperature is a function of the molecular motion within the substance. Heat conduction is therefore not possible in a vacuum.
Deregistration
This mode of heat transfer is known as ‘radiation’. It is a flow of electromagnetic waves emitted by any object, regardless of its temperature. Electromagnetic radiation is temperature-dependent: the higher the temperature, the greater the radiation, and vice versa.
This phenomenon can increase the body’s temperature when it is absorbed, or conversely, decrease it when it is emitted.
Convection
When a fluid—whether liquid or gas—flows, it carries a certain amount of thermal energy with it; this phenomenon is known as convection. There are two types of convection. Natural convection occurs when the fluid is set in motion by gravity and temperature changes. Forced convection, as the name suggests, occurs when the fluid’s movement is driven by a fan or a pump, for example.
Thermal management of electronics
The increasing miniaturization of electronic components requires controlled heat dissipation. Indeed, excessively high temperatures drastically reduce the lifespan of your printed circuit boards (PCBs).
Our engineering department creates precise models of your enclosures and components. Through simulation, we optimize:
As a result, we guarantee that your junctions will remain below critical thresholds, even under severe conditions.
