Which way is better for high temperature cold storage, water cooling and air cooling? Please explain in detail, such as one-time input cost, electricity fee, maintenance fee, refrigeration energy efficiency, etc.

If the investment cost is 3P, 1W, the electricity fee is 500/ month, the maintenance fee is 200 yuan, and the refrigeration efficiency is 3.

Air cooling is a cooling method, that is, air is used as the medium to cool the objects that need to be cooled. Usually, it is to increase the surface area of the cooled object, or to speed up the rate of air flowing through the object per unit time, or to use both methods. The former can be realized by adding fins on the surface of the object, which are usually hung outside or fixed on the object to make the heat dissipation more efficient. The latter can use a fan (electric fan) to enhance the ventilation and cooling effect. In most cases, adding fins can greatly improve the cooling efficiency.

According to the principle of water cooling, it can be divided into active water cooling and passive water cooling. In addition to all accessories of water-cooled radiator, active water cooling needs to install a cooling fan to assist heat dissipation, which can greatly improve the heat dissipation effect. This water-cooling method is suitable for DIY overclocking players with fever. Passive water cooling does not install any cooling fan, but only relies on the water-cooled radiator itself to dissipate heat. At most, add some cooling fins to assist heat dissipation. This water cooling method is worse than active water cooling, but it can achieve the effect of complete silence, which is suitable for mainstream DIY overclocking users.
