Application of Fiberglass Profiles in Cooling Tower Industry
Application of Fiberglass Profiles in Cooling Tower Industry
Cooling towers are devices that use water to transfer heat from industrial processes or buildings to the atmosphere. They are widely used in power plants, chemical plants, oil refineries, and other industries that require cooling. Cooling towers can be classified into two types: natural draught and cell type.
Fiberglass Profiles for Natural Draught Cooling Towers
Natural draught cooling towers are tall structures that rely on the natural convection of air to cool the water. They have a large diameter at the base and a smaller diameter at the top, creating a chimney effect that draws air through the tower. The water is sprayed from the top of the tower and falls down through a fill material that increases the contact surface between water and air.
Fiberglass profiles are used for structural support, fan blades, and other components in natural draught cooling towers. Fiberglass profiles have several advantages over traditional materials such as steel or wood:
- They are lightweight, which reduces the foundation requirements and transportation costs. - They have a high strength-to-weight ratio, which allows for larger spans and higher load capacity. - They are corrosion-resistant and decay-resistant, which increases the durability and reduces the maintenance costs. - They have low thermal conductivity, which reduces the heat loss and improves the cooling efficiency.
Some examples of fiberglass profiles used in natural draught cooling towers are:
Cell type cooling towers are modular units that consist of a fan, a fill material, a water distribution system, and a casing. They can be arranged in parallel or series to form a cooling tower system. Cell type cooling towers can be further divided into two types: counterflow and crossflow.
Fiberglass profiles are also used for structural support, fan blades, and other components in cell type cooling towers. They have similar advantages as in natural draught cooling towers, but also offer some additional benefits:
- They are easy to assemble and disassemble, which facilitates the installation and relocation of cooling tower systems. - They have high dimensional stability and low thermal expansion, which reduces the deformation and stress caused by temperature changes. - They have good electrical insulation and fire resistance, which enhances the safety and performance of cooling tower systems.
Some examples of fiberglass profiles used in cell type cooling towers are:
- Circular tubes, square tubes, rectangular tubes, I-beams, C-channels, angles, and flat bars for structural support. - Small size blade profiles (less than 1m of cable) for fan blades. - Rods, bars, strips, and plates for grating, decking, handrail systems, access ladders, coatings, and other components.
