High temperatures can also cause hot spots within the capacitor and can lead to its failure. The most common cooling methods include self-cooling, forced ventilation and liquid cooling. The simplest method for cooling capacitors is to provide enough air space around the capacitor so it will stay sufficiently cool for most applications.
In higher power cases, the larger heat load may require additional cooling by means of an external heat dissipator or heat sink (not unknown, but not common with capacitors since they take up a lot of space); a fan, which can forcefully direct cooling air over the capacitor; or liquid cooling.
Cooling a capacitor helps to enhance its performance as well as its reliability. Cooling will extend its life; taking away more heat from the capacitor can also give it more power-carrying ability. Murray Slovick dig into more details of methods and principles how to cool capacitors in his article published by TTI Market Eye.
There are many other methods to remove capacitor heat. Some are as simple as ensuring a good conduction path between the closed end of the part and a large thermal conductor. Folded fin material wrapped around the capacitor and attached with a clamp is another innovative way to increase cooling surface area.
Folded fin material wrapped around the capacitor and attached with a clamp is another innovative way to increase cooling surface area. The folded fin material is flexible, and is available in many fin thicknesses and densities. This additional cooling surface area can make a big difference in capacitor lifetime.
However, such methods of cooling (which only bring the cooling medium into contact with the external case of the capacitor) are not as efficient thermally as the designs of water-cooled capacitors where water is passed through the interior of the capacitor so that heat is extracted as close as possible to its where it is generated.
Capacitor heat loads are small: typically 5 to 10 Watts in a 3 inch diameter capacitor. One way to cool these capacitors is to attach the part to an aluminum chassis or panel.
