Description
Technical Field
The utility model relates to a marine diesel engine, specifically speaking are diesel engine oil pan cooling device.
Background
The internal combustion engine is an important power machine and is widely applied to many fields of industrial production and social life. Among them, the diesel engine is an important branch of the internal combustion engine, and has an irreplaceable position in the aspects of power of transportation vehicles, agricultural machinery and engineering machinery.
The oil sump has the function that the closed crankcase can prevent other impurities from entering, collects and stores lubricating oil flowing back from the moving pairs of the diesel engine, dissipates part of heat and prevents the lubricating oil from being oxidized and denatured.
Along with the continuous improvement of the strengthening degree of the engine, the thermal load is higher and higher, the lubricating oil temperature is extremely easy to be overhigh, so that the lubricating effect of the engine is influenced, and even the lubricating failure is caused, so that the power economy, the reliability and the like of the engine are influenced.
In the oil pan of the diesel engine, hot lubricating oil is reduced in density due to temperature rise and is concentrated on the upper layer, cold oil is on the lower layer, and the existing cooling device of the oil pan of the diesel engine is only concentrated on the lower part of the oil pan of the diesel engine for cooling, so that lubricating oil in the oil pan cannot be effectively cooled. The hidden trouble caused by the over-high temperature of the lubricating oil still exists.
Disclosure of Invention
An object of the utility model is to provide a marine low-speed engine oil pan cooling device is reinforceed to the commonality strong, the cooling effect is showing.
The purpose of the utility model is realized like this:
the utility model discloses marine low-speed engine oil pan intensive cooling device, characterized by: including the oil pan, set up the oil inlet on the outer wall of oil pan upper end, set up the oil drain port on the outer wall of oil pan lower extreme, set up the cooling water pipeline in the oil pan, the cooling water import of cooling water pipeline is located the outside of oil pan one side, and the cooling water export of cooling water pipeline is located the outside of oil pan opposite side, and the cooling water pipeline is located the bottom surface inner wall of oil pan, sets up condenser tube annular fin on the outer wall of condenser tube, and the bottom surface inner wall of oil pan sets up the intensive heat transfer recess.
The utility model discloses can also include:
1. and a diversion turbine for guiding the upper layer lubricating oil into the lower part of the oil pan and sending the lower layer lubricating oil to the upper part is arranged at the bottom inside the oil pan.
2. The upper part of the oil pan is provided with a wind wave prevention baffle plate along the longitudinal direction of the oil pan.
The utility model has the advantages that:
1. the flow guide turbine is additionally arranged, so that the hot lubricating oil can be effectively cooled. The current situation that the hot lubricating oil cannot be cooled at the upper layer in the existing cooling mode, and the lubricating oil with lower temperature is cooled at the bottom is avoided.
2. The annular fins are arranged outside the water cooling pipeline, so that equipment is not added in a limited space, and heat exchange is effectively enhanced.
3. The oil pan bottom plate groove is arranged, so that lubricating oil at the bottom of the oil pan can be cooled by surrounding air.
Drawings
FIG. 1 is a schematic view of an annular fin and heat exchange groove;
FIG. 2 is a schematic view of an oil pan with a inducer added thereto;
fig. 3 is an overall schematic view of the present invention.
Detailed Description
The invention will be described in more detail below by way of example with reference to the accompanying drawings:
with reference to fig. 1-3, the cooling device for the bottom shell of the marine low-speed engine of the present invention mainly comprises: the oil-cooling oil pan comprises an oil inlet 1, an oil discharge port 2, a cooling water inlet 3, a cooling water outlet 4, a wave-proof ring groove 5, an oil pan reinforcing rib 6, an oil pan bolt hole 7, a diversion turbine 8, a reinforced heat exchange groove 9 and cooling water pipe annular ribs 10.
The oil pan upper portion is equipped with storm-proof baffle 5, sets up on the oil pan floor and strengthens heat transfer recess 9, and the two combines each other, prevents to bump because of sea stormy waves and makes the lubricating oil in the oil pan incline to leak.
The rectangular groove 9 on the lower part of the oil pan becomes fins for heat exchange between the lower part of the oil pan and air, and the convective heat exchange and the radiant heat exchange between the lower bottom plate of the oil pan and the air are enhanced.
The water cooling pipeline at the lower part of the oil pan reasonably utilizes sea water at sea for heat exchange, and a circle of annular fins are additionally arranged outside the heat exchange pipeline, so that the heat exchange between the water cooling pipeline and lubricating oil is facilitated to be strengthened.
The utility model discloses set up two water conservancy diversion turbines bottom traditional diesel engine oil pan, utilize these two turbines to concentrate the cooling with the lower part of the leading-in oil pan of the higher lubricating oil of upper strata temperature in the oil pan, send the oil pan upper strata with the oil pan lower floor already refrigerated lubricating oil again.
The utility model discloses reform transform the bottom plate design of traditional oil pan, set up the multichannel recess on the bottom plate of oil pan bottom, the interpolation of recess, the deepening of liquid level in the oil pan that becomes prevents to rock because the marine stormy waves the lubricating oil that arouses in the oil pan and spills over and arouse the lubricating oil loss. In addition, the recesses form heat-dissipating ribs outside the oil pan bottom plate, so that the oil pan bottom plate can dissipate heat with the aid of the surrounding air.
For the effect of realizing above-mentioned intensive heat transfer, except above-mentioned action, the utility model discloses still set up sea water cooling water pipeline bottom the oil pan to set up the annular fin outside cooling water pipeline, strengthen the heat transfer between cooling water and the hot lubricating oil.
As shown in fig. 3, hot lubricant enters the oil pan from the oil inlet 1 and is then sucked into the bottom of the oil pan by the guide turbine 8. The hot lubricant is cooled at the bottom of the oil pan by the cooling water pipe with the annular ribs 10 together with the rectangular grooves 9 at the bottom of the oil pan. Cooling seawater in the cooling water pipeline enters from a cooling water inlet 3, and flows out from a cooling water pipeline 4 after the lubricating oil is cooled. The cooled oil flows out from the oil drain port 2.
The specific principle of the utility model is that:
the higher lubricating oil of temperature is because the lower gathering of density is on the upper strata of oil pan, can not obtain the effective cooling that is located the cooling device of oil pan, then the utility model discloses a two water conservancy diversion turbines inhale hot lubricating oil from upper portion down to carry out the cooling device with the lower part and add the rib and strengthen, reach the more powerful lubricating oil cooling effect.
