The oil cooler of the utility model adopts a new arranging mode and shape, which greatly optimizes the water flow mode of a water jacket in the cooler and increases the cooling efficiency of the cooler core, water flow is optimized, the flow resistance is lowered, and the consistency of the water flow of each cylinder is increased. The oil cooler which is provided by the utility model has high heat exchange efficiency, simple and compact structure, good versatility, good manufacturability for production and processing and easy installment. The oil cooler of the utility model is suitable for inner oil coolers of heavy and medium diesel engines.
Description
Technical field
The utility model relates to a kind of diesel engine machine oil cooler, relate in particular to a kind ofly be used for, built-in machine oil cooler that large diesel engine is used.
Background technique
At present, in, the development of heavy high-speed diesel engine is more and more higher to emission request, specific power, bursting pressure, this has just proposed higher requirement to heat exchange, the heat dispersion of the lubricating and cooling system of diesel engine.In summer, in, that the situation that the water temperature height can't cruising appears in heavy truck is more and more general.Usually the settling mode that adopts all is to strengthen pump capacity, strengthens the air quantity of radiation fan, certainly will cause Mechanical Reliability to reduce like this, and engine power consumption is big, and oil consumption is risen.By analysis, usually the machine oil cooler core adopts horizontal positioned, and the water inlet direction is subjected to stopping of machine oil cooler core to cause current confusion, machine oil cooler chip chamber water velocity slow, and heat exchange efficiency reduces.Change arrangement of parts if adopt, the mode machine oil cooler of optimizing water flow field can improve radiating efficiency, reduces the water flow field pressure loss, has solved the high problem of water temperature, reduces the water pump power consumption, has reduced the oil consumption of motor indirectly.
Summary of the invention
For in satisfying, Heavy diesel oil acc power density improves day by day, to the high request that lubricating and cooling system proposes, the utility model provide a kind of in, the machine oil cooler used of large diesel engine, thereby realize the optimization of engine cooling system, reduce the water pump power consumption, and then reduce engine consumption.
The utility model provides a kind of machine oil cooler, comprise cooler head 1, cooler core 3, O shape circle 4, cooler head pad 5, the flange of cooler core 3 adopt O shape circle 4 to be connected the tilting mode of cooler core 3 employings with engine body, preferred included angle is for being 15～45 degree with horizontal sextant angle, and cooler head 1 is fixed on the motor machine by cooler head pad 5.
In the utility model machine oil cooler, the preferred flow guide type cooler head that adopts of cooler head 1 is provided with on cooler head 1 from the but guide plate of water inlet to the cooler core 3 of conduction cooling, and the guide plate from cooler core 3 to each cylinder liner.Preferably guide plate is set at engine body and cooler head 1 guide plate relevant position.
In the utility model machine oil cooler, bypass valve 2 is arranged on the engine body, is installed in the cross-over connection oil duct between body filler opening flange (docking with the flange of cooler core 3) and the main oil gallery.If cooler core 3 inner blockage phenomenon, machine oil can not be smoothly by entering the main oil gallery of body, and at this moment bypass valve 2 is opened, and part enters main oil gallery without the machine oil bypass of cooling, plays the effect of a protection main oil gallery oil flow rate.
Owing to adopt technique scheme, the utlity model has following beneficial effect:
1, cooler core 3 adopts tilting mode, has optimized the direction of current, has improved the flow velocity of cooling water on the cooler central layer, has improved heat exchange efficiency.
2, the reasonable use of cooler head 1 and body guide plate improves the cylinder uniformity of engine cooling water greatly.
3, the resistance of current reduces greatly, and power and lift requirement decline to water pump have reduced the oil consumption of motor indirectly.
4, the fluororubber O shape circle of technology maturation is adopted in cooler core 3 sealings, the reliability height, and maintenance cost is also low.
5, bypass valve 2 is arranged on the engine body, has simplified the design of cooler.

Among the figure: 1-cooler head, 2-bypass valve, 3-cooler core, 4-O shape circle, 5-cooler head pad.
Embodiment
Below in conjunction with accompanying drawing embodiment is illustrated:
As shown in Figure 1, fluororubber O shape circle 4 is inserted in the O shape ring recess of cooler core 3 upper flanges, cooler head pad 5 is installed, be connected with engine body with 4 bolts, cooler head 1 is installed then, last bypass valve 2 is installed in the corresponding hole of body and gets final product.
The utility model relates to the machine oil cooler of diesel engine, its cooler core 3 adopts the tilting structure of proper angle, cooler head 1 adopts the flow guide type cooler head, realize that the cooling water inlet is to the middle cooling water guide functions of cooler core, and the cooling water guide functions from cooler core 3 to each cylinder liner, guide cooling water is from cooler core middle (shown in Fig. 2 arrow) athwart.Obtain maximum heat exchange efficiency with this, the cooling water overwhelming majority can be conducted through cooler core, walked around the oil inlet and outlet at cooler core two ends, cooling water flow by the guiding of engine body and cooler head, enters each cylinder liner equably after cooler core.Thereby optimized water flow field, and can improve radiating efficiency, reduce the water flow field pressure loss, reduce the water pump power consumption, reduced the oil consumption of motor indirectly.Its compact structure is simple, heat exchange efficiency is high, and versatility is good, has reduced cost.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
