Introduction: In the history of the development of closed cooling
towers, other coatings coated on carbon steel cannot be compared
with the galvanizing process under the normal cooling tower water
quality conditions defined on the left. No matter how peculiar,
other coating layers and electrostatic coatings are not as
successful as galvanizing.

can be added according to user requirements. (All electrical
components are used in Chint products)
Industrial Cooling Tower Introduction:
Cooling towers are divided into: open-type FRP cooling towers,
closed water circulation cooling towers, industrial chillers, etc.,
the cooling methods are different, but the purpose of the final
purchase is consistent, through the equipment to reduce the
temperature of the water, thereby achieving The purpose of water
recycling. The closed cooling tower complete equipment consists of
a main engine, an expansion water tank, a circulation pump and an
electric control cabinet. The main engine is composed of shell,
heat exchanger, fan, sprinkler system, water eliminator, water tank
and pipeline valve.
Working principle and mode
During operation, the heat carrier medium (cooling water, oil or
other liquid) is driven by the system circulation pump, circulating
between the heat exchanger coil and the cooling equipment (such as
power supply, furnace body, etc.), and the heat of the heat carrier
medium conducts to the coil tube wall . The spray water is evenly
sprayed on the heat exchanger to form a uniform water film on the
outer surface of the heat exchanger coil. Under the action of the
fan, the cold air enters the tower from the air inlet below the
tower body, and flows back through the surface of the heat
exchanger with the spray water, fully contacts, and carries out
latent heat and sensible heat exchange, and some water evaporates,
so that the spray water temperature is lowered. The saturated hot
and humid air after the heat is absorbed by the fan to the
atmosphere, the low-temperature spray water absorbs the heat of the
coil and then flows into the lower tank of the tower body, and then
is sent to the spray system by the spray pump. In this way, the
cooling medium in the heat exchanger is cooled and cooled. During
the heat exchange process, the heat transfer medium in the coil is
not in direct contact with the air, so that the quality
characteristics are maintained without contamination,
concentration, moisture absorption and volatilization.
The closed cooling tower has two modes of operation, namely: air
cooling, air cooling + spraying. The switching of the two modes is
automatically carried out by the electronic control system
according to the working conditions to achieve energy saving.
Features:
1. Fully enclosed circulation cooling, no debris enters the cooling
pipeline system resulting in pipeline blockage.
2. Soft water circulation cooling, no water scale is formed at high
temperature, causing fouling of the cooling pipeline system, and
the pipeline is overheated and damaged.
3. Small footprint, no need to excavate the pool, easy to access,
save water and reduce energy consumption.
4. Air cooling + evaporation endothermic double cooling method,
high cooling efficiency.
5. It can directly cool water, oil, alcohol, quenching liquid, salt
water and chemical liquid. The medium has no loss and stable
composition.
6. Due to the closed cycle, the medium is not affected by the
environment and will not pollute the environment.
7. Automatic digital control temperature, automatic liquid level
control, energy saving, high precision, easy to operate.
8. The cooling water does not come into contact with the outside
world, and the heat is dissipated by the coil;
9. When the wet bulb drops to a certain temperature, the cooling
host can be stopped to provide a cold source;
Advantage:
1. High-efficiency airfoil type axial flow fan: airfoil type
aluminum alloy fan blade, galvanized ring plate wheel hub, its
design shape conforms to aerodynamic principle, low speed under
high efficiency ensures low noise operation of the fan, angle can
be free Adjust to achieve maximum horsepower and optimum
performance.
Features: high efficiency, low speed, low energy consumption, low
noise and low vibration.
2. Filler and water collector: The filler is in the form of a film.
The filling process is vacuum-absorbed by UV-resistant and
chemical-resistant PVC. The louver remover is a component of the
filler. Formed integrally to confine water to the filler layer.
Other manufacturers may use exterior louvers so that water can
easily freeze due to the outflow of the packing layer and is
difficult to detect due to the proximity of the cooling tower. If
you want to continue using the cooling tower in the winter,
especially with natural cooling, then using integrated louvers can
eliminate your concerns. Compact design, strong hydrophilicity,
high heat dissipation efficiency, easy to disassemble and clean,
easy to replace, water collector is PVC material, triple process
design. The drift water can reach 0. 005% or less of the water flow
rate, and there is no splash on the air inlet surface.
3. Coil tube: The serpentine coil tube is connected to the
all-welded box-shaped header, and the coil tube and the header are
welded to the hot-dip zinc. The design of the coil tube is to
discharge all the refrigerant at the time of shutdown.
The core design: the upper part is the heat dissipation coil, the
lower part is the heat dissipation filler, and the spray water and
the fresh air simultaneously cool the heat exchange tube. The heat
transfer driving force of the coil heat exchanger is enhanced, and
the heat exchange capacity per unit coil area is greatly improved.
Each coil manufacturing has undergone a pressure leak test to
ensure its perfect quality.
Coil tube integrated design, easy to handle and repair, cleaning.
