Utility model content
The problems such as radiating is needed for solution is above-mentioned, the utility model devises a kind of radiator of steam turbine.
A kind of radiator of steam turbine, including turbine and heat emission fan, the casing of the turbine include shell and inner casing, The inner casing is surrounded by the shell, and inner casing fixation is located in the cavity pocket of outer cover, the upper casing of the inner casing and described outer The upper casing of shell is fixedly connected, and the lower casing of the inner casing is fixedly connected with the lower casing of the shell, and the rotor of the steam turbine turns It is dynamic to be mounted in the cavity of the inner casing;The left side wall of the shell is equipped with heat emission fan, and the left side wall is equipped with air inlet hole, described The right side wall of shell is equipped with heat release hole.
Preferably, the forward and backward side wall of the shell is equipped with arc convex at the inner casing, so that the heat dissipation at the inner casing The runner of air-flow becomes smaller.
Preferably, the inner casing is equipped with cooling line, and the top that the water inlet pipe of the cooling line passes through the inner casing is logical The top for crossing water pump and cooling tank connects, bottom and the cooling tank of the outlet pipe of the cooling line across the inner casing Bottom connection.
Preferably, the inner casing outer surface is equipped with wavy cooling fin, is formed and is dissipated between the adjacent cooling fin The passage of heat.
Preferably, the cooling pot bottom is equipped with condenser, and the outlet pipe of the cooling line is passed through through the condenser In the tank body of the cooling tank.
Compared with the prior art, the advantages of the utility model are: the utility model using hydronic cooling side Method has saved resource;The shell of the utility model, inner casing design, so that inner casing can come into full contact with cooling gas, to take away More heats, increase rate of heat dispation;The utility model uses the air-cooled method combined with water cooling, so that cooling effect is more Add.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the structure chart of the utility model;
Fig. 3 is the utility model shell mechanism schematic diagram.
Wherein, 1- turbine, 2- heat emission fan, 3- shell, 4- inner casing, 5- air inlet hole, 6- rotor, 7- heat release hole, 8- cooling fin, 9- cooling tank, 10- cooling line.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with the drawings and specific embodiments, the utility model is further described.
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.
It is described on base, the utility model using hydronic cooling means, saved resource;Outside the utility model Shell, inner casing design, so that inner casing can come into full contact with cooling gas, to take away more heats, increase rate of heat dispation;This Utility model uses the air-cooled method combined with water cooling, so that cooling effect is more.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
