How do you cool a capacitor?

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.

How does a water cooled capacitor work?

In most modern water-cooled capacitors, the cooling medium passes through the interior of the component. The cooling conditions in place will help determine the performance and operating lifespans of these water-cooled capacitors.

Why do capacitors need to be cooled?

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.

Are water cooled capacitors more efficient?

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.

Does a capacitor need a heat dissipator?

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.

What are water cooled capacitors used for?

These water–cooled capacitors are specially designed for use in inductive heating and melting plants for power factor improvement and also for tuning of the circuits for varying inductive loads. The liquids that are commonly used in such systems are water, a mixture of water and chemical solutions, and de-ionized water.
