Evaporative Air Cooler

I. Overview

Evaporative air cooler, utilizing the evaporation of spray water, carries the air out of the tower for cooling and heat exchange of the circulating medium inside the tubes, ensuring complete isolation of the circulating medium from the outside environment.

Due to the vaporization of the spray water, a large amount of steam mixes with the air, increasing humidity. This requires a powerful exhaust fan, also known as a blower, to remove the saturated, high-humidity, and high-enthalpy air from the tower. On the surface, it's just air cooling, along with the evaporation of the spray water, commonly referred to as an evaporative air cooler, sometimes also called an evaporative cooler.

2. Working Principle

1. Vapor Latent Heat: Similar to closed cooling towers, it relies on the evaporation of spray water outside the heat exchange tubes to absorb the latent heat of vaporization, carrying away the thermal energy of the industrial circulating water medium inside the enclosed heat exchange tubes.

2. Interfacial Heat Exchange: Sprayed water and air are completely isolated from the circulating medium, with no contact at all, only heat exchange, no contact.

III. Main Advantages

1. No Evaporation: Only temperature reduction, no evaporation or consumption; the circulating medium is completely isolated from the external air, with no contact at all. There is no medium evaporation, consumption, or impurity entry, ensuring the stability of the internal medium composition.

2. Scale-Free: As there is no evaporation, the concentration of scaling ions like calcium, magnesium, and sulfate in the medium remains unchanged, hence scaling does not occur.

3. Easy Maintenance: All coils are fully visible, making maintenance convenient and repairs easy.

4. Equipment features four-sided air intake, low air resistance, and reduced fan power.

Section 4: Application Scenarios

Commonly used in heavy industries such as iron and steel metallurgy, casting smelting, petrochemicals, chemical light industry, machinery, and electricity. Resistant to scaling, reduces evaporation, often used for cooling demineralized water and pure water, cooling inside enclosed heat exchange tubes, completely isolated from the external atmosphere.

1. Iron and Steel Metallurgy: Blast furnaces, continuous casting and rolling, molders, air compressors, etc.

2. Large Casting: Melting furnaces, variable-frequency drives, quenching fluids, etc.

3. Petroleum Refining: Reactors, smelting furnaces, heat exchangers, etc.
