Developments

There are passive and active thermal management systems.

In passive systems, highly heat-conductive materials are used to reduce thermal resistance. There are three generations passive thermal management systems already.

Aluminum, copper, silver alloys, gold alloys, beryllium alloys belong to the first generation of high-heat-conductive materials.

Composite materials, such as AlSiC, belong to the second generation.

New generation of materials for thermal management bases on high-heat-conductive forms of carbon is being actively developed currently. 

In active heat sink systems, the heat generated is removed by supplying a cooler gas or liquid. Such heat sink systems can cope with greater thermal loads than passive ones. However, In active heat sink systems, it is assumed to use engines, valves, and piping systems, which generally reduces the reliability of such systems in severe operating conditions.

The most reliable systems will be those where heat removal is provided only by high- heat-conductive materials. However, the best high-heat-conductive materials will be ineffective if there are many interfaces with high thermal resistance on the way of heat removal.

In 2016, “Metal-Composite” entered the market of led radiators and mastered the production of several types of radiators for led lamps.

Today “HeatLab” company has competence and the practical experience:

• in mathematical modeling and optimization of the process of removing heat fluxes,

• in the design of final solutions using high-heat-conducting materials of our own design for led lamps, including special-purpose ones.

The proposed solutions can be applied in special conditions where standard lamps are not able to provide the specified service life and reliability of lighting systems. We are ready to offer our services to customers who are faced with a sharp reduction in weight, material consumption while increasing the power and reliability of led lighting devices. Such solutions require the use of special materials and devices, accurate calculation and simulation of heat dissipation in various environmental conditions, depending on the power and operating modes of the led device.
