Abstract

The invention discloses an air cooler for nuclear power steam turbine generators. The air cooler comprises a shell, a water inlet pipe plate and a water outlet pipe plate are respectively fixed at two ends of the shell, and a plurality of cooling fins are fixed on cooling pipes; the air cooler further comprises a cathodic current protection unit which comprises a direct-current power supply and an adjustable resistor, the negative electrode of the direct-current power supply is connected with the cooling fins, cooling pipe sleeves among the cooling fins are contacted with one another to be electrically connected, a positive electrode of the direct-current power supply is connected to the water inlet pipe plate or the water outlet pipe plate, the cooling fins close to the water inlet pipe plate or the water outlet pipe plate are contacted with the water inlet pipe plate or the water outlet pipe plate to form a circuit, and the adjustable resistor is serially connected in the circuit. By the arrangement, the air cooler can adapt to cool nuclear power steam turbine generator sets in marine atmospheric environment, the air cooler is high in corrosion resistance, capable of reducing electrochemical corrosion and long in service life.

Description

technical field [0001] The invention relates to an air cooler, in particular to an air cooler for a nuclear power steam turbine generator. Background technique [0002] With the increasing depletion of ore dyestuffs such as coal, oil, and natural gas, and the limited amount, uneven distribution, and low energy density of wind energy, solar energy, and geothermal energy, nuclear power has become the preferred new energy in my country's "Twelfth Five-Year Plan" energy. Air coolers are key equipment for turbogenerators in nuclear power plants. Its performance directly affects the stability and efficiency of the generating set. Based on the comprehensive consideration of water resources, energy saving and safety of nuclear power installations, most of the reused or newly-built nuclear power plants in my country are built in coastal areas and use seawater as the medium to cool the interior of the turbogenerators in nuclear islands and conventional island systems through heat exc...
