The invention provides a ship
turbine cooling device and method, and relates to the technical field of ship
turbine cooling. The circulating driving module comprises a variable-frequency
circulating pump; the heat exchange module comprises a heat exchange
pipe which is wound on the outer side of a cylinder body of the ship
turbine; the
temperature control module comprises a temperature sensor and a
control unit, the temperature sensor is connected with the cylinder body, and the
control unit is used for controlling operation of the variable-frequency
circulating pump according to a detection result of the temperature sensor and controlling the variable-frequency
circulating pump to operate at a first rotating speed when the detection result is smaller than a
lower limit value of a set temperature threshold value; when the detection result is within the set temperature threshold range, the variable-frequency circulating pump is controlled to conduct temperature linear adjustment according to the detection result, and when the detection result is larger than the upper
limit value of the set temperature threshold, the variable-frequency circulating pump is controlled to operate at the second rotating speed; the problems that in the prior art, in ship turbine cooling and heat dissipation, cooling reliability is insufficient, and economical efficiency is poor are solved.
