Abstract
The invention 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 arranged in the finned tube, and a fin arranged on the finned tube, the finned inner tube is provided with a corrugated inner tube which is disposed at the center of the finned inner tube, and the outer surface of the corrugated inner tube and the inner surface of the finned inner tube form an oil guide passage. The device is simple in structure, stable in running, good in heat-radiating effect and suitable for heat radiation of the gearbox lubricating oil and hydraulic oil of other large-and-medium-sized hydraulic equipment; when the gearbox lubricating oil flows in the finned tube of the finned tube radiator, high-viscosity lubricating oil can be realized to form turbulent flow.
Description
Technical field
The present invention 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 is in the cooling of heat radiator fin Bottomhole pressure, and can not realize the Turbulence Flow of the higher lubricant oil of viscosity in pipe in cooling runs, heat transfer effect is low.
Summary of the invention
It is simple that the technical problem to be solved in the present invention is to provide a kind of 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 is in the fin Bottomhole pressure of finned tubular radiator, the device that the higher lubricant oil of viscosity forms a kind of Turbulence Flow can be realized.
For solving the problems of the technologies described above, of the present inventionly a kind ofly change the device of gear box lubricating oil at heat radiator fin Bottomhole pressure, comprise fin tube, be arranged on pipe in the fin in fin tube, be arranged on the fin on fin tube, in fin, pipe is provided with corrugated inner tube, and corrugated inner tube is placed in tube hub in fin, and in the outer surface of described corrugated inner tube and fin, the internal surface of pipe forms Oil Guide passage.
As the further improvement to the technical program, corrugated inner tube is connected on the internal surface of pipe in fin by connection end, and connection end is in " 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 corrugated inner tube.
As the further improvement to the technical program, a lateral section of connection end is arcuation.Cross section is that arcuation reduces Oil Guide resistance.
As the further improvement to the technical program, one end of corrugated inner tube conically, can effectively reduce Oil Guide resistance.
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, or turbulent flow; Re> 4000 is turbulent flow: 2000<Re<4000 or is laminar flow, or turbulent flow.Obtain fluid flow state in non-circular section runner, Re<500 is laminar flow, and Re>500 is turbulent flow.Therefore, method provided by the invention, makes lubricant oil when by Oil Guide gap, changes original flow profile, effectively can form Turbulence Flow, and the fluid particle that lubricant oil is formed, in movement process, mixes mutually, interts, effectively promote heat transfer effect.
Common fin tube with change the heat radiation comparative trial data sheet of gear box lubricating oil compared with the device of heat radiator fin Bottomhole pressure:
By above comparison of test results: the present invention's more former common tube radiating efficiency, 1. under natural cool condition, improves 15.8% and 2. improves 36.9% under additional fan cooled condition.
