Reduce the mobility of cooling water, can thus deteriorate cooling effect of the cooling water to cooling oil；If water-cooling muscle (3b-2)
Number is very few, although can increase the mobility of cooling water, but can reduce connecing for cooling water and water-cooling muscle (3b-2) again
Contacting surface is accumulated, and so equally can also deteriorate cooling effect of the cooling water to cooling oil, so the number of water-cooling muscle (3b-2) is needed
Especially to consider.It is also desirable to the matching problem of oil cooling radiating ribs (3a-2) and water-cooling muscle (3b-2) be considered, so as to allow
Cooling water preferably cools down cooling oil, consequently facilitating cooling oil cools down engine chamber.
In the present case, it is respectively provided with an inlet nozzle (7) in two mounting holes in outer panel (1) outer plate surface and goes out
Oil nozzle (8), wherein inlet nozzle (7) are connected with the kidney-shaped fuel feed hole (J) on interior plate (2) and coldplate (3) body, and it is described go out
Oil nozzle (8) is connected with the kidney-shaped oil outlet (C) on interior plate (2) and coldplate (3) body.
, can be by inlet nozzle (7) from external world's input lubricating oil using said structure, the lubricating oil passes through interior plate (2)
After the kidney-shaped fuel feed hole (J) on coldplate (3) body, into engine gearbox, and from interior plate (2) and coldplate (3)
Kidney-shaped oil outlet (C) on body flows to oil outlet (8), finally flows to the cooling device in the external world, and this cyclic process is referred to as outer
Circulation, its effect is cooling engine gearbox.
For the ease of manufacture, the body of the oil cooling labyrinth (3a) and water cooling labyrinth (3b) and coldplate (3) is monoblock type
Structure.
Beneficial effect：Main cool down coldplate by original one side of the invention is adjusted to present two-sided cooling, and this is cold
But plate integrates the design for employing reduction oil cooling radiating ribs height and increase water cooling labyrinth, and wherein oil cooling radiating ribs height can be protected
The contact area of cooling oil and oil cooling radiating ribs is demonstrate,proved, the mobility of cooling oil is can guarantee that again, so as to reduce the temperature of cooling oil；Together
When, this cooling system cools down cooling oil by cooling water, so can more reduce the temperature of cooling oil, so as to improve cooling oil
To the cooling effect of engine chamber, and the present invention is simple in construction, it is easy to implement.
