Using Natural and Forced Convection to Cool Control Panels

In the quest to find the most energy and space efficient cooling units for advanced electrical control panels, Noren’s clients often benefit from the simplest solutions. In many cases, that means utilizing natural or forced convection to eliminate the need for clunky, power-hungry air conditioning solutions. Deciding on natural convection cooling units depends on a number of factors. If forced convection is recommended, then the exact specifications, including amount of flow, will also depend on the specific application. Therefore, the first step to choosing the right option is to perform a comprehensive analysis and design a thermal management system that meets your application’s unique needs.

Natural Convection vs. Forced Convection

Natural convection occurs when a fluid changes density at various temperatures. In a heat exchanger, the fluid closest to electrical waste heat absorbs the heat and becomes less dense, rising up so that more fluid can replace it. The less dense fluid is allowed to release its heat into a heat sink, which dissipates it as the fluid cools and returns repeat the process. The consistent motion of the fluid creates a natural convection current that prevents heat spots from developing within an electrical enclosure.

Natural convection can help save a significant amount of energy by eliminating the need to run air conditioning or compressing equipment continuously. However, some applications may require the assistance of an external source, such as a fan, to accelerate the transfer of heat. Known as forced convection, the process must be carefully designed to ensure maximum heat transfer according to variations in pressure across the heat sink.
