Gas Turbine Generator Air Water Cooler

Generator air-water cooler is a compact heat exchanger. It consists of several sets of heat exchanger tubes and fins, water chamber, tube plate, side beams and other components. The fins and heat exchanger tubes are expanded to achieve full contact and efficient heat transfer; the two ends of the heat exchanger tubes are sealed with the tube plate at both ends by strength expansion; the sealing between the tube plate and the water chamber is realized by sealing gasket and threaded connection.

Cooling medium from the water chamber of the inlet into the heat exchanger tube, after one or more return, and then by the water chamber of the outlet back to the circulating water system, the refrigerant through the heat exchanger tube and its outside the fins will be covered by the transfer of cold heat exchange with the generator in the superheated gas, to maintain the temperature of the gas inside the generator is lower than the set value, to ensure that the equipment at a certain temperature within the normal operation of the temperature. The gas inside the generator is usually accompanied by a fan system to guide the air flow. The air-water cooler usually consists of one, two or four cooling cores, the base shape design should be adapted to the generator manufacturer's generator structure requirements.

Core Advantages
Efficient heat dissipation: the specific heat capacity of water is much higher than that of air, which can quickly take away the high heat load; the air-cooled side utilizes the ambient air and reduces the dependence on water source.
Energy saving and environmental protection: compared with the pure water cooling system, reduce the consumption of cooling water; compared with the pure air-cooled system, the heat dissipation capacity is stronger, avoiding the problem of high temperature capacity reduction.
Wide adaptability: suitable for high temperature, high humidity or dusty environment (e.g. desert power station, ship power system).

Key application scenarios
Gas turbine generator sets:
Industrial power generation (combined cycle power plant, distributed energy).
Ship power (naval gas turbine needs to adapt to salt spray environment).
Special environmental requirements:
Water-scarce areas: air-cooling-based, water-cooling-assisted peak heat dissipation.
High-temperature climate: compensation for air-cooled efficiency loss by water cooling.
