Description
Technical field
The present invention relates to a kind of heat-exchange device, the sink of specifically a kind of heat exchange.
Background technique
The application of gear-box in machinery widely, and is an important mechanical transmission component, and its major function has: 1, speedup or deceleration, is exactly the speed-change gear box often said.2, change transmission direction, such as we can by power vertical transmission on another rotatingshaft by two Bevel Gear Drive.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 driven shaft 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 casing and naturally cools, attaches fan cooled, subsidiary water-cooled coil pipe cooling and subsidiary 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 is run and is required the expenditure of energy, and by the impact of rotation speed of the fan, can not environmentally temperature automatic adjustment oil temperature; In addition, fan can make dust from flying, causes secondary environmental pollution.
The cooling of water-cooled coil pipe needs continuous cooling water supply, and coil pipe inner cooling water is easy to fouling in the course of the work, causes cooling effect greatly to reduce after fouling; And quality of cooling water easily corrodes coil pipe when containing corrosive ions; In addition, winter conditions temperature is lower than the heat-preserving anti-freezing problem also will considering cooling water after shutdown when 0 DEG C.
There is the use problem of similar air-cooled and water-cooled coil pipe equally 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 because of lubricating oil viscosity high-leveled and difficult to start, cause oil pump cannot normal fuel injection.
The consequence that gear-box high oil temperature causes is: 1, aggravate deterioration of lubricant 2, accelerate shaft seal aging 3, shorten bearing life 4, oil film is thinning, affects gear and bearing lubrication effect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of natural cooling heat radiator of gear box lubricating oil, and this apparatus structure is simple, reasonable, effectively can solve the cooling problem of the large gear-box of heating value.
For solving the problems of the technologies described above, the natural heat dissipation device of a kind of gear box lubricating oil of the present invention, comprises radiating fin, connecting plate, oil inlet hole, oil outlet and conduction oil, and radiating fin is rectangle, vertically arranges, is connected between radiating fin with radiating fin by bumped head; Multiple radiating fin is fixed on steelframe, forms a pack heat dissipation device; Sink is provided with an oil inlet hole and an oil outlet.
Radiating fin internal fixtion has bellows, and bellows becomes " S " type; Bellows, by connecting tube and other radiating fin UNICOMs, becomes the circulation canal of lubrication.
The gap of radiating fin and bellows adopts conduction oil to fill.
The sidewall of radiating fin has vent.
As the further improvement to technical solution of the present invention, connecting plate is provided with fixing bolt.
As the further improvement to technical solution of the present invention, radiating fin is provided with oil hole and exhaust port.
As the further improvement to technical solution of the present invention, in radiating fin, conduction oil is tiny structure to the pressure of radiating fin, ensures that positive compressive strain does not occur radiating fin steel plate, does not occur bulge phenomenon.
The natural cooling heat radiator of gear box lubricating oil of the present invention, during work, the ripple Bottomhole pressure that lubricant oil is arranged at radiating fin internal fixtion, lubricant oil transfers heat to the conduction oil outside bellows, conduction oil transfers heat to radiating fin, and like this, radiating fin is rapid thermally equivalent just, then radiating fin is by convection current and heat loss through radiation, transfers heat to air.
Beneficial effect of the present invention is: structure is simple, and volume is little, easy for installation, and long service life is easy to maintenance, does not need extra fan and cooling water, by natural convection air heat radiation and heat loss through radiation, free from environmental pollution.
Can motor-drive pump be used with the matching used oil circulation pump of this sink, when oil temperature in gear-box is lower than 60 DEG C, does not need to start oil pump, restart this sink etc. oil temperature higher than 60 DEG C.
This radiator fabricating cost is low, and operating cost is low, does not need to safeguard, becomes the new paragon at present working environment and heat radiation being had to the gear-box of particular/special requirement and other large and medium-sized hydraulic equipment, lubricant oil, hydraulic oil heat radiation.
Test data table of the present invention:
During initialization, heat is first passed to conduction oil by lubricant oil, and heat dissipating capacity is slightly larger, and after waiting conduction oil temperature to rise very soon, heat is constantly fallen apart in air by spreader surface, finally reaches thermal equilibrium.
