Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
The drawings and specific embodiments, the present invention is further explained.
Embodiment
As shown in Figure 1 to Figure 3, a kind of radiator of steam turbine, including turbine 1 and heat emission fan 2, the turbine 1
Casing includes shell 3 and inner casing 4, and the inner casing 4 is surrounded by the shell 3, and the fixation of inner casing 4 is located at 3 cavity of shell
Interior, the upper casing of the inner casing 4 is fixedly connected with the upper casing of the shell 3, the lower casing of the lower casing of the inner casing 4 and the shell 3
It is fixedly connected, the rotor 6 of the steam turbine is rotatably installed in the cavity of the inner casing 4；The left side wall of the shell 3 is equipped with
Heat emission fan 2, the left side wall are equipped with air inlet hole 5, and the right side wall of the shell 3 is equipped with heat release hole 7.
The forward and backward side wall of the shell 3 is equipped with arc convex at the inner casing 4, so that the radiating airflow at the inner casing 4
Runner become smaller.
The inner casing 4 is equipped with cooling line 10, and the top that the water inlet pipe of the cooling line 10 passes through the inner casing 4 passes through
Water pump is connect with the top of cooling tank 9, bottom and the cooling tank of the outlet pipe of the cooling line 10 across the inner casing 4
9 bottom connection.
4 outer surface of inner casing is equipped with wavy cooling fin 8, and it is logical to form heat dissipation between the adjacent cooling fin 8
Road.
In the present embodiment, the cooling pot bottom is equipped with condenser, and the outlet pipe of the cooling line is through the condensation
Device is passed through in the tank body of the cooling tank.
The course of work and principle: when turbine needs to radiate, cooling tank is opened, so that coolant liquid is flowed into cooling line, takes away
The partial heat of turbine, while heat emission fan is opened, extraneous cooling gas is filled in the cavity of shell, when by inner casing,
The heat of inner casing is taken away, is then flowed out from the heat release hole opposite with heat emission fan；Cooling gas is in the high spot for flowing to shell, meeting
Because channel narrows are so that air pressure herein increases, flow velocity is speeded, so that radiating rate is speeded.
