Side, the connector include the first interface for connecting ozzle, the second interface for connecting external water pipe, the diameter of the second interface
Greater than the diameter of first interface, the diameter of the condenser pipe is not more than nozzle diameter, the prominent connector of the first interface, and first
Interface includes threaded area, fastening zone, and the threaded area is provided with the external screw thread to match with the internal screw thread of outer race tube, and described first
Interface is connected between the outer race tube of ozzle and inner ring pipe, and the outer race tube is provided with pinch grip at the proximal port, and described the
Two interfaces pass through clamp connection external water pipe.
Preferably, the shell is the design of undercut type, is both provided with condenser pipe in three face of shell, increases described device
Heat exchange area.
Preferably, the junction between the first interface and ozzle is provided with gasket.
Preferably, the fastening zone outer surface is provided with protrusion, increases surface roughness.
Preferably, clip includes connector, arc section, and bolt hole is provided on the connector, and two groups of clips are used cooperatively, and is led to
The bolt hole use for crossing joint is bolted.
Preferably, non-slip mat is provided in the clip.
Preferably, the condenser pipe is semicircle shape, and the straightway bottom surface of the semicircle shape condenser pipe is close to heat source.
Preferably, it is connected between the first interface and second interface by arc inner cavity.
The utility model has the advantages that being compared to traditional approach, an external cooling device does not destroy original ram's horn structure, not shadow
Beauty is rung, and heat can be taken away in time, environment temperature is reduced, guarantees the reliability of point element.Moreover, external water pipe
Diameter is greater than nozzle diameter, therefore, when condensed water enters described device, since pipeline section product becomes smaller, can make cold
Condensate in said device accelerate by flowing velocity, improves heat exchange condensation effect.

Specific embodiment
The utility model is further elaborated with reference to the accompanying drawings and examples.
As shown in Figure 1 to Figure 3, a kind of ram's horn cooling device for the cooling of steam turbine end cap, comprising: shell 1, setting exist
Condenser pipe 2 inside shell 1, the ozzle that 2 inlet and outlet of condenser pipe are set, the company for connecting ozzle and external water pipe 10
Fitting.The shell 1 is the design of undercut type, is both provided with condenser pipe 2 in 1 three face of shell, increases the heat-transfer surface of described device
Product.The condenser pipe 2 is semicircle shape, and the straightway bottom surface of the semicircle shape condenser pipe 2 is close to heat source.The ozzle includes outer ring
Pipe 3 and shorter inner ring pipe 4, the outer race tube 3 are provided with internal screw thread, are provided with bevel edge 401 at 4 port of inner ring pipe.Institute
Stating connector includes the first interface for connecting ozzle, the second interface 7 for connecting external water pipe 10, the diameter of the second interface 7
Greater than the diameter of first interface, connected between the first interface and second interface 7 by arc inner cavity.The condenser pipe 2
Diameter is not more than nozzle diameter.The prominent connector of the first interface, first interface includes threaded area 5, fastening zone 6, the spiral shell
Line area 5 is provided with the external screw thread to match with the internal screw thread of outer race tube 3, and 6 outer surface of fastening zone is provided with protrusion, increases table
Surface roughness.The first interface is connected between the outer race tube 3 of ozzle and inner ring pipe 4, between the first interface and ozzle
Junction be provided with gasket 9, the outer race tube 3 is provided with pinch grip 14 at proximal port, and first interface passes through screw thread
After connection, pinch grip 14 is screwed, equipment is entirely connected and further seals fastening.The second interface 7 is connected by clip
