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.
Some types of capacitors perform worse in cold weather. The extent of this worsening is inversely proportional to the quality of the capacitor. For example, '99%' of electrolytic capacitors 'work less' in the cold. This issue might be more perceptible on cheaper products.
In the context of your question, 'work less' in the cold refers to electrolytic capacitors performing less effectively. Approximately 99% of electrolytic capacitors exhibit this behavior, and it might be more noticeable on cheaper products.
Every 10° C increase in internal temperature halves the component lifetime. The structure and materials used in the capacitor make heat dissipation more difficult. To operate properly, the case must be electrically isolated from the core where heat is generated. The voltage breakdown of the insulation materials is often in excess of 350 volts DC.
Capacitors are used in lighting to smooth signals, suppress interference and in some instances provide burst power. They can be either plastic film, ceramic, or aluminum, and often use a combination of all three dielectrics in a single ballast.
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.
