Description
Technical field
The present invention relates to a kind of device of general heat exchange, the sink of specifically a kind of heat exchange.
Background technique
The application of gear-box in machinery is very extensive, and is an important mechanical part, and its major function has: 1, acceleration or deceleration, is exactly the speed-change gear box often said.2, change transmission direction, such as we can by power vertical transmission to another rotatingshaft with two cone gears.3, moment of rotation is changed.When transmitting same power, fireballing axle transmitting torque is little, and slow-footed axle transmitting torque is large.4, clutch function: we by separating two meshed gears originally, can reach the object that motor and load are separated.Such as brake clutch etc.5, distributed power.Such as we with a motor, can drive multiple from axle by gear-box main shaft, thus realize the function of a multiple load of driven by engine.
The cooling of current gear-box mainly contains that casing cools naturally, the cooling of fan cooled, water-cooled coil pipe and air-cooled or water-cooled lubricating oil station cooling.
Casing nature cooling capacity is limited, and the existing natural type of cooling is generally used for the little gear-box of heating value, is not suitable for the cooling problem of the large gear-box of heating value.
Fan cooled only blows gear case body, and radiating effect is poor, and patent of the present invention is the radiating effect that the lingering remnants of past customs of the fan utilizing gear-box to carry strengthens this device, greatly strengthen heat dissipation potential of the present invention.
Water-cooled coil pipe inner cooling water is easy to fouling in the course of the work, causes cooling effect greatly to reduce after fouling.
There is the use problem of similar air-cooled and water-cooled coil pipe in air-cooled and water-cooled petrol station, and when petrol station uses oil pump feed, once oil temperature is lower than 5 DEG C, oil pump feed difficulty, even causes oil pump to drive equally.
Summary of the invention
The technical problem to be solved in the present invention is to provide the air-cooled of a kind of gear box lubricating oil and adds water-cooling type finned tubular radiator, gear box lubricating oil Wind-cooling type finned heat exchanger can use together with the fan supporting with gear-box, the cooling effect of enhanced fin and air, improves the heat dissipation potential of heat exchanger; And realize the Turbulence Flow of the high lubricant oil of viscosity when Bottomhole pressure by arranging interior pipe, improve heat transfer effect further.
For solving the problems of the technologies described above, the air-cooled of gear box lubricating oil of the present invention adds water-cooling type finned tubular radiator, comprise water-in and water-out interface, into and out of oily interface, fin tube, described fin tube is fixedly installed on connecting plate, and fin high frequency welding, on tube outer surface, is provided with interior pipe in described fin tube; Gap between described inner tube outer surface and described fin tube internal surface forms Oil Guide passage; The hollow space of described interior pipe is cooling water passage; Cooling water passage between fin tube with fin tube by string connecting tube waterborne with go here and there connecting tube under water and be connected; Oil Guide passage between fin tube with fin tube is connected by bumped head; Described radiator is provided with wind shield in the both sides of fin tube.
As to technical solution of the present invention further improvement, cooling water center position is provided with the effect that zinc bar can realize antirust, the antiscale in Cooling Process.
As the further improvement to technical solution of the present invention, described connecting plate is arranged with pilot hole, can be fixed this device.
As the further improvement to technical solution of the present invention, zinc bar is fixed by zinc bar fixing bolt.
The air-cooled gap added between the inner tube outer surface of water-cooling type finned tubular radiator and described fin tube internal surface of gear box lubricating oil of the present invention forms Oil Guide passage; In described spiral, the hollow space of pipe is cooling water passage; Conduit pipe between fin tube with fin tube is connected by connecting tube; Oil Guide passage between fin tube with fin tube is connected by bumped head; Described radiator is provided with wind shield in the both sides of fin tube.Said structure can realize air-cooled while add water-cooled, improving radiating effect.
Reynolds through great many of experiments, and adopts dimensional analysis and principle of similitude method, have found the critical flow velocity that laminar flow or turbulent flow appear in fluid: the fluidised form Re<2000 of pipe inner fluid is laminar flow, and Re>4000 is turbulent flow; 2000<Re<4000 or be laminar flow, or turbulent flow.For the fluid flow state in non-circular section runner, Re<500 is laminar flow; Re>500 is turbulent flow.Due in fin tube pipe circle pipeline in add interior pipe, zinc bar is turn increased in the middle of interior pipe, therefore, lubricant oil and the flowing of cooling water in Oil Guide passage, conduit pipe change original pipe shape, effectively can form Turbulence Flow, the fluid particle formed in each comfortable passage of lubricant oil, cooling water, in movement process, mixes mutually, interts, effectively promote heat transfer effect.
