Description
Technical field
The utility model is related to diesel engine cooling technical field, more particularly, to a kind of lube oil cooler for diesel engine and its cold
But system.
Background technology
Diesel engines at present is to accelerate lubricating oil radiating it is kept the device of reasonable temperature by oil cooler part.
On high-performance, powerful reinforcing stimulus, because thermic load is big, it is necessary to install oil cooler.Oil cooler is arranged
In lubricant passage way, the temperature of lubricating oil is controlled using the temperature of cooling water.When lubricating oil temperature is high, dropped by cooling water
Temperature；During engine start, then absorbing heat from cooling water makes lubricating oil improve temperature rapidly.Oil cooler is cast by aluminium alloy
Housing, protecgulum, bonnet and copper core pipe composition.In order to strengthen cooling, pipe is outer to be set with fin again.Cooling water outflows in pipe
Dynamic, lubricating oil is in Bottomhole pressure, and both carry out heat exchange.
But the oil cooler that general diesel engine is used only controls lubricating oil temperature in the case of heat engine, not control is started
Lubricating oil temperature under machine initial launch low temperature condition.The frictional work of engine initial launch engine interior part motion is influenceed, just
The operation fuel consumption that begins is big.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is to provide a kind of diesel engine lubricating oil cooling
Device and its cooling system, with the purpose for the frictional work for reaching the inner part motion of reduction engine initial operation stage.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is used for：
The lube oil cooler for diesel engine, including cooler head and cooler core, the cooler core are located in cooler head,
Also include be used for control lubricating oil whether the lubricating oil temperature and Stress control by-passing valve Jing Guo cooler core, the lubricating oil temperature
Degree and Stress control by-passing valve are located on cooler head.
The cooler head is the lid being molded by die casting.
The cooler core is the core body by lead welding and shaping after copper and stainless steel assembling.
Lubricating oil temperature and the Stress control by-passing valve is to realize open and close controlling using wax temperature control and mechanical spring
By-passing valve.
The by-passing valve is located at the lubricating oil inlet on cooler head.
The diesel engine lubricating oil cooling system, including oil sump, lubricating oil pump, oil filter, main oil gallery and engine are each
Lubricating structure, in addition to the lube oil cooler for diesel engine, the lube oil cooler for diesel engine are located at lubricating oil pump and oil filtration
Between device.
The utility model compared with prior art, with advantages below：The lube oil cooler for diesel engine and its cooling system
Reasonable in design, compact conformation, integrated level is high, and improving cost is low；Rubbing for engine initial operation stage inner part motion can be reduced
Work(is wiped, so as to reduce the fuel consumption of this time.
Brief description of the drawings
The content expressed by each width accompanying drawing of this specification and the mark in figure are briefly described below：
Fig. 1 is the utility model cooling system block diagram.
Fig. 2 is the utility model cooler partial schematic diagram.
In figure：
1. cooler head, 2. lubricating oil temperatures and Stress control by-passing valve, 3. cooler cores.
Embodiment
Below against accompanying drawing, by the description to embodiment, further detailed is made to embodiment of the present utility model
Thin explanation.
As depicted in figs. 1 and 2, the lube oil cooler for diesel engine, including cooler head 1 and cooler core 3 and lubricating oil
Temperature and Stress control by-passing valve 2, cooler core 3 are located in cooler head 1, wherein, cooler head 1 be by die casting into
The lid of type, cooler core 3 is the core body by lead welding and shaping after copper and stainless steel assembling.Compact conformation, integrated level is high, cost
It is low.
Lubricating oil temperature and Stress control by-passing valve 2 are used to control whether lubricating oil is carried out lubricating oil by cooler core
Cooling.It is preferred that, lubricating oil temperature and Stress control by-passing valve are to realize open and close controlling using wax temperature control and mechanical spring
By-passing valve.
Cooler head 1 is provided with lubricating oil inlet and lubricating oil outlet, and lubricating oil temperature and Stress control by-passing valve are located at
At lubricating oil inlet on cooler head, lubricating oil outlet has two-way, all the way by cooler core, and another road is without subcooler
Core directly arrives oil filter.
The diesel engine lubricating oil cooling system, including oil sump, lubricating oil pump, lube oil cooler for diesel engine, the machine being sequentially connected
Oil rectifier, main oil gallery and each lubricating structure of engine, each lubricating structure of engine are connected with oil sump.
When oil temperature is higher than 105 DEG C, lubricating oil is largely cooled down by cooler core to lubricating oil, works as oil temperature
Lubricating oil largely directly arrives oil filter without cooler core during less than 90 DEG C.Engine initial operation stage, lubrication
Oil is not cooled, and lubricating oil is rapidly entered main oil gallery, makes lubricating oil temperature fast lifting to optimum condition temperature, and reduction is started
The frictional work of machine inner part motion, so as to reduce the fuel consumption of this time.This scheme passes through complete vehicle test, examination
Test effect preferable.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that the utility model implement not by
The limitation of aforesaid way, as long as employing the improvement for the various unsubstantialities that design of the present utility model and technical scheme are carried out,
Or it is not improved by it is of the present utility model design and technical scheme directly apply to other occasions, it is of the present utility model protect
Within the scope of shield.
