After 40 days of unremitting efforts, the composite evaporative air cooler produced by GH Cooling for Mengxi Coking Plant arrived at the customer's site on time and completed installation.

An air cooler is a heat exchange equipment that uses air in the surrounding environment as the cooling medium to cool high-temperature working fluids. It is widely used in various departments such as petrochemical, oil refining, chemical, metallurgical, electric power, refrigeration, etc. Composite high-efficiency air cooler is a new type of cooling and exchange equipment that integrates latent heat and sensible heat exchange mechanisms and optimizes the combination of evaporative cooling (condensation) and wet air cooling. Compared to air cooler, composite high-efficiency air cooler is not only safe, reliable, water-saving, and energy-saving, The development of composite high-efficiency air coolers will become a trend to adapt to the overall trend and environment of national energy-saving and economic development, as they have environmentally friendly performance and are more economical in the early stages of investment and use.

Structural characteristics of composite evaporative air cooler:

1. The optimized combination of "evaporation+air cooling" is used for cooling, which reuses the saturated wet air and residual energy of the fan, improving the cooling efficiency to a certain extent. Most importantly, the actual energy consumption is minimized The cooling effect of a composite high-efficiency air cooler is equivalent to the effective combination of a wet air cooler and water cooling. Through the evaporation coil, it can enter the saturated wet air of the air-cooling fins. In this case, the cooling process medium has the same actual effect as a wet air cooler, and the surface of the evaporation coil is covered with spray water. Its cooling effect will be more obvious than that of a water cooler.

2. The equipment is formed through the combination of many modules, and the modules can be effectively replaced. Through modular structural design, the manufacturing, operation, maintenance, and repair of the equipment are further simplified. Taking the actual on-site requirements as an important reference, the free combination of modules can be achieved. In the actual maintenance process, the workload can be reduced proportionally, and some modules can also be stopped, Implement and implement online and non-stop maintenance work. If there is a leakage problem with individual tube bundles, the module should be cut off, but it does not affect the overall operating condition of the equipment and can effectively complete the module replacement task

3. The coil bundle design has obvious flexible characteristics, which can completely eliminate the thermal stress formed in the manufacturing process and operation processes of the equipment. At the same time, the coil can reasonably use a variety of special-shaped and efficient heat exchange tubes. The more common ones are corrugated pipes and spiral tubes, which can increase the Reynolds number of the fluid inside the tube and realize the overall improvement of the heat exchange coefficient. At the same time, Placing the condensing coil as a whole in an environment with a temperature of 465 degrees Celsius and conducting hot-dip zinc anti-corrosion treatment can effectively reduce the probability of scaling when the thickness of the zinc layer reaches 100mm, and ensure that the service life of the coil exceeds 10 years
