Description
Technical field
The present invention relates to a kind of heat-exchange device, specifically a kind of heat abstractor of heat exchange.
Background technology
Application in plant equipment for the gear-box widely, and is an important mechanical transmission component, and it is main
Function has：1st, speed or slow down it is simply that the change gear box often said.2nd, change transmission direction, for example we are with two circular cone teeth
Wheel transmission can be by power vertical transmission to another rotary shaft.3rd, change rotating torque.When transmitting same power, speed is fast
Axle transmitting torque little, slow-footed axle transmitting torque is big.4th, clutch function：We can be engaged originally by separately two
Gear, reach electromotor and the purpose separated of load.Such as brake clutch etc..5th, distribute power.For example we are permissible
With an electromotor, multiple driven shafts are driven by gear-box main shaft, thus realizing the work(of the multiple load of driven by engine
Energy.
The cooling of gear-box at present mainly has casing natural cooling, subsidiary fan coolling, subsidiary water-cooled coil pipe to cool down and attached
Band is air-cooled or water-cooled lubricating oil station cools down.
Casing natural cooling is limited in one's ability, and existing the natural type of cooling is generally used for the little gear-box of caloric value, uncomfortable
Close the cooling problem of the big gear-box of caloric value.
Fan coolling is run and is required the expenditure of energy, and is affected it is impossible to be automatically adjusted according to ambient temperature by rotation speed of the fan
Oil temperature；In addition, fan can make dust from flying, cause secondary environmental pollution.
The cooling of water-cooled coil pipe needs continuous cooling water supply, and in coil pipe, cooling water is easy to fouling in the course of the work, knot
Cooling effect is led to substantially reduce after dirt；And quality of cooling water contains and easily corrodes coil pipe during corrosive ions；In addition, winter conditions temperature
It is also contemplated that the heat-preserving anti-freezing problem of cooling water after shutting down when degree is less than 0 DEG C.
Air-cooled equally exist similar air-cooled and water-cooled coil pipe use problem with water-cooled petrol station, and petrol station is supplied using oil pump
When oily, once oil temperature is less than 5 DEG C, oil pump because lubricating oil viscosity high-leveled and difficult to start, cause the oil pump cannot normal fuel injection.
The consequence that gear-box high oil temperature causes is：1st, aggravation deterioration of lubricant 2, accelerate that axle envelope is aging 3, shorten the bearing longevity
Life 4, oil film are thinning, affect gear and bearing lubrication effect.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of natural cooling heat abstractor of gear box lubricating oil, this device
Simple and reasonable for structure, the cooling problem of the big gear-box of energy effectively solving caloric value.
For solve above-mentioned technical problem, a kind of natural heat dissipation device of gear box lubricating oil of the present invention, including fin,
Connecting plate, fuel feed hole, oil outlet and conduction oil, fin is rectangle, vertically arranges, passes through punching press between fin and fin
End socket connects；Multiple fin are fixed on steelframe, form a pack heat dissipation device；Heat abstractor is provided with a fuel feed hole and one
Oil outlet.
It is fixed with corrugated tube, corrugated tube becomes " S " type in fin；Corrugated tube passes through connecting tube and other fin UNICOMs,
Become the circulation canal of lubrication.
Fin adopts conduction oil to fill with the gap of corrugated tube.
Passage is had on the side wall of fin.
As the improvement further to technical solution of the present invention, connecting plate is provided with fixing bolt.
As the improvement further to technical solution of the present invention, fin is provided with oil filler point and steam vent.
As the improvement further to technical solution of the present invention, in fin, conduction oil is micro- negative to the pressure of fin
Pressure, it is ensured that fin steel plate does not occur positive compressive strain, occurs without bulge phenomenon.
The natural cooling heat abstractor of the gear box lubricating oil of the present invention, during work, lubricating oil fixation in fin sets
The ripple Bottomhole pressure put, lubricating oil transfers heat to the conduction oil outside corrugated tube, and conduction oil transfers heat to fin,
So, fin passes through convection current and heat loss through radiation with regard to rapid thermally equivalent, then fin, transfers heat to air.
The beneficial effects of the present invention is：Structure is simple, small volume, and easy for installation, long service life is easy to maintenance, no
Need extra fan and cooling water, by natural convection air radiating and heat loss through radiation, free from environmental pollution.
Matching used oil circulation pump can use electrodynamic pump with this heat abstractor, when in gear-box, oil temperature is less than 60
DEG C when, be not required to start oil pump, restart this heat abstractor etc. oil temperature higher than 60 DEG C.
This radiator low manufacture cost, operating cost is low, is not required to safeguard, become at present working environment and radiating are had special
The gear-box requiring and other large and medium-sized hydraulic test, lubricating oil, the new paragon of hydraulic oil radiating.
The test data table of the present invention：
During initialization, heat is first passed to conduction oil by lubricating oil, and heat dissipation capacity is slightly larger, waits heat conduction oil temperature to go up quickly
After rising, heat is constantly scattered in the air by spreader surface, finally reaches thermal balance.

Specific embodiment
The present invention is further detailed explanation for connection with figures below：
A kind of natural heat dissipation device of gear box lubricating oil of the present invention, including fin 7, connecting plate 5, fuel feed hole, goes out
Oilhole 8 and conduction oil 2, fin 7 is rectangle, vertically arranges, multiple fin 7 are fixed on steelframe, fin 7 and fin
Connected by bumped head 9 between 7；Form a pack heat dissipation device.Heat abstractor is provided with a fuel feed hole 10 and an oil outlet
8.
It is fixed with corrugated tube 1, corrugated tube 1 becomes " S " type in fin 7；Corrugated tube 1 passes through connecting tube and other fin 7
UNICOM, becomes the circulation canal of lubrication.
The gap of fin 7 and corrugated tube 1 is filled using conduction oil 2.
Passage 3 is had on the side wall of fin 7.
Connecting plate 5 is provided with fixing bolt 6.Fin 7 is provided with oil filler 4 and steam vent 11.Conduction oil in fin 7
The pressure of 2 pairs of fin 7 occurs without bulge phenomenon for tiny structure it is ensured that fin 7 steel plate does not occur positive compressive strain.
The natural cooling heat abstractor of the gear box lubricating oil of the present invention, during work, lubricating oil is being flowed by fuel feed hole 10
Enter heat abstractor, heat abstractor is flowed out by oil outlet 8.Flow in the corrugated tube 1 that lubricating oil is fixedly installed in fin 7,
Lubricating oil transfers heat to the conduction oil 2 outside corrugated tube 1, and conduction oil 2 transfers heat to fin 7, so, fin 7
With regard to rapid thermally equivalent, then fin 7 passes through convection current and heat loss through radiation, transfers heat to air.Oil filler 4 and steam vent
11 match in that context it may be convenient to fill radiating oil.
