Abstract
The utility model discloses a device for changing flowing of gearbox lubricating oil in a radiator finned tube. The device comprises the finned tube, a finned inner tube and fins, wherein the finned inner tube is arranged in the finned tube, and the fins are arranged on the finned tube. A corrugated inner tube is arranged in the finned inner tube and located in the center of the finned inner tube, and an oil guide channel is formed by the outer surface of the corrugated inner tube and the inner surface of the finned inner tube. The device is simple in structure, stable in operation, good in radiating effect and suitable for radiating gearbox lubricating oil and hydraulic oil of other large and middle-sized hydraulic devices, and in flowing of the gearbox lubricating oil in the finned tube of a finned tube radiator, turbulent flowing can be formed by the lubricating oil with high viscosity.
Description
Technical field
The utility model relates to a kind of parts of device of heat exchange, the parts of the sink of specifically a kind of heat exchange.
Background technique
Existing gear box lubricating oil flows cooling in heat radiator fin pipe, cooling, in servicely can not realize lubricant oil that viscosity the is higher Turbulence Flow in pipe, and heat transfer effect is low.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, stable, good heat dissipation effect, be applicable to the heat radiation to gear box lubricating oil and other large and medium-sized hydraulic equipment hydraulic oil, and during gear box lubricating oil flows in the fin tube of finned tubular radiator, can realize the device that lubricant oil that viscosity is higher forms a kind of Turbulence Flow.
For solving the problems of the technologies described above, a kind of gear box lubricating oil mobile device in heat radiator fin pipe that changes of the present utility model, comprise fin tube, be arranged on the fin inner tube in fin tube, be arranged on the fin on fin tube, fin inner tube is provided with ripple inner tube, and ripple inner tube is placed in tube hub in fin, and the internal surface of the outer surface of described ripple inner tube and fin inner tube forms Oil Guide passage.
As the further improvement to the technical program, ripple inner tube is connected to by connection end on the internal surface of fin inner tube, and connection end is " one " font.The connection end of yi word pattern can effect increase Oil Guide passage effectively pass through space.
As the further improvement to the technical program, connection end is two and mutually vertical.Orthogonal connection end can play good fixation to ripple inner tube.
As the further improvement to the technical program, a lateral section of connection end is arcuation.Cross section is arcuation and reduces Oil Guide resistance.
As the further improvement to the technical program, it is conical that one end of ripple inner tube is, and can effectively reduce Oil Guide resistance.
Reynolds process great many of experiments, and adopt dimensional analysis and principle of similitude method, found out fluid and occurred laminar flow or turbulent critical flow velocity: the fluidised form Re<2000 of pipe inner fluid has been laminar flow, or turbulent flow; Re> 4000 is turbulent flow: 2000<Re<4000 or is laminar flow, or turbulent flow.For obtaining fluid flow state in non-circular section runner, Re<500 is laminar flow, and Re>500 is turbulent flow.Therefore, the method that the utility model provides, makes lubricant oil when by Oil Guide gap, changed original flow profile, can effectively form Turbulence Flow, the fluid particle that lubricant oil forms is in movement process, mix mutually, intert, effectively promote heat transfer effect.
Common fin tube and the heat radiation comparative trial data sheet that changes gear box lubricating oil mobile device in heat radiator fin pipe and compare:
By above comparison of test results: 1. the more former common tube radiating efficiency of the utility model under natural cool condition, has improved 15.8% and 2. improved 36.9% under additional fan cooled condition.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Known in conjunction with Fig. 1, Fig. 2, Fig. 3, change gear box lubricating oil of the present utility model mobile device in heat radiator fin pipe, comprise fin tube 5, be arranged on the fin 2 on fin tube 5, be arranged on the fin inner tube 3 in fin tube 5, fin inner tube 3 is provided with ripple inner tube 4, and ripple inner tube 4 is placed in fin inner tube 3 centers, and the internal surface of the outer surface of described ripple inner tube 4 and fin inner tube 3 forms Oil Guide passage 1.
Ripple inner tube 4 is connected to by connection end 6 on the internal surface of fin inner tube 3, and connection end 6 is " one " font.Connection end 6 is two and mutually vertical.One lateral section of connection end 6 is arcuation.It is conical that one end of ripple inner tube 4 is.
Of the present utility model simple in structure, stable, good heat dissipation effect, be applicable to the heat radiation to gear box lubricating oil and other large and medium-sized hydraulic equipment hydraulic oil, and gear box lubricating oil can be realized the lubricant oil that viscosity is higher and form a kind of Turbulence Flow in flowing in the fin tube of finned tubular radiator.
Above embodiment is not done any pro forma restriction to invention technological scheme; if do not departing within the scope of technical solution of the present invention; utilize technical solution of the present invention institute disclosure to do the technical local equivalence of changing or modifying and implement, all still belong in the scope of protection of the invention.
