A circulating cooler is a device used to cool fluids, typically used for heat exchange in industrial production processes. According to different working principles and application scenarios, circulating coolers can be divided into the following categories:
1. Water cooler: Water cooler is one of the most common types of circulating cooler, which absorbs heat through the circulation of water and then dissipates heat through the circulation of cooling water. Water coolers are widely used in various industrial production processes, such as electricity, chemicals, metallurgy, etc.
2. Air cooler: The air cooler utilizes the principle of air convection to cool the fluid and transfer heat to the surrounding environment. Air coolers are usually suitable for situations where water cooling cannot be used, such as in dry areas or environments with poor air quality.
3. Oil cooler: The oil cooler is mainly used to cool industrial liquids such as lubricating oil or hydraulic oil. It reduces the temperature of the oil by passing hot oil through the cooling pipes in the cooler and using external media such as water or air to absorb heat.
4. Evaporative cooler: The evaporative cooler utilizes the evaporation process of liquid to absorb heat and convert it into latent heat of evaporation. Evaporative coolers are usually suitable for situations that require a large amount of cooling, such as air conditioning systems, cold storage, etc.
