Frequently asked questions
What support does Phoenix Contact provide in the area of thermal management?
Phoenix Contact supports you with catalog values, online simulations, personal consultation including simulation services, and (individually adapted) heatsinks.
How are components of different heights and sizes ideally connected to the heatsink?
The optimum thermal connection is implemented by individual adjustments of the heatsink. This is usually done by a milling operation on the heatsink.... View more

The graphs of the diagrams provide information on which power the components may supply in the respective housing in order not to exceed a temperature difference to the environment. The slope of the straight line describes the thermal conductance of the system. The cases shown differ, on the one hand, in that one features full-surface heating while the other features heating of a hotspot of 20 x 20 mm and, on the other hand, in that one has a printed circuit board installed in the housing and one does not have a housing.

The integrated heatsinks from Phoenix Contact dissipate heat from the hotspot by means of heat conduction via thermally conductive material (TIM). The heatsink releases this heat in the form of radiant energy and via convection between the slats to the environment. The stack effect is utilized, during which the heated air rises and is displaced by cold air.
View lessWhat other options are there for thermal optimization?
In many cases, rearranging the hotspots or installing vents is sufficient. A simulation of the thermal conditions provides information on which option is best suited.... View more
